The Flawed Volkswagen Dieselgate Settlement & How to Fix it


While I typically keep a narrow focus on the content of this blog, that being to obsessively cover the BMW i3 electric car, occasionally I'll post something if I feel it has particular importance to the electric vehicle industry as a whole. Such is the case with this entry. For those of you unfamiliar with the Volkswagen "Clean Diesel" scandal, it basically amounts to the fact that Volkswagen cheated the emission testing in place and flooded the market with highly-polluting vehicles that were improperly called "Clean Diesel".

As a result, the Volkswagen Group was fined a record amount of money and forced to buy back or fix nearly half a million cars in the US which were operating in conflict with US emission laws. As part of the penalty, Volkswagen was ordered to pay a 2 billion dollar penalty, which would be used to fund zero emission infrastructure, and improve access to ZEVs.

On face value, the proposed Dieselgate settlement initially seemed like it might provide the monumental boost to public electric vehicle charging infrastructure that many have been waiting for. The Volkswagen Group has agreed to pay $14.7 billion for intentionally deceiving the public, and selling “Clean Diesel” vehicles that emit up to 40 times the legal limit of certain pollutants. There are three parts to the settlement:

• Buybacks and financial settlements to owners of 466,000 affected vehicles: $10.0 billion

• Compensation for the illegal cars' environmental impact: $2.7 billion

• Fund new infrastructure and access for zero-emission vehicles: $2.0 billion

However, as the October 18th court date approaches at which time U.S. District Judge Charles Breyer is set to decide whether to grant final approval to the settlement, the details of the infrastructure part of the settlement are, to say the least, concerning.

As it stands now, the Volkswagen Group will have little oversight as to how they spend the 2 billion dollars earmarked for infrastructure and improving access to ZEVs. (CARB will be reviewing and approving the California projects and the EPA will be doing the same for the rest of the country) I question why Volkswagen will have ANY discretion as to how the penalty funds are spent, let alone near complete control over it. Volkswagen isn’t in the electric vehicle infrastructure business. In fact, they are barely in the electric vehicle business as it is today. The only OEM that I’d actually trust to do infrastructure implementation properly would be Tesla, because their business model depends on it, and they’ve been doing it very successfully for half a decade already.

What if Volkswagen decides to start their own EV infrastructure company and use the funds to pay their own subsidiary to manufacture and install the equipment? (*EDIT: I've since read the full proposed transcript and I don't believe they could actually do this, so that's one good thing) We could end up with substandard equipment, and a network that has poor customer service, inadequate repairs and outrageous pricing models. Even if they were to do it right, and the company was successful, why should Volkswagen benefit from the penalty? What if they offered free charging for the first couple years so they could put all the competition out of business and then raised the prices to unreasonable levels? Indeed, you could do a lot of damage with 2 billion dollars and this settlement doesn’t provide any safeguards against that in its current form.

Last week ChargePoint asked the courts to intervene, and Judge Breyer accepted the plea. It’s ChargePoint’s position that the way the settlement is currently constructed, Volkswagen is “solely responsible for every aspect of selecting the National (ZEV) investments…including timing and locations”. Among concerns that Volkswagen isn’t experienced enough in the electric vehicle infrastructure business to have sole discretion over sure a large fund, Chargepoint is also concerned that Volkswagen will have too much say over the future of electric vehicle charging. Since the amount of funds available in the fund is so great, Volkswagen could dictate the fate of many of the existing companies and decelerate advancements, often fostered by fair competition: “If the settling defendants become the sole source for electric vehicle infrastructure, it will stifle innovation in industries designed to support electric vehicle recharging.”

I have to agree with Chargepoint on this issue. I don’t believe it’s in the best interest of the electric vehicle industry to allow Volkswagen to have sole discretion over how to spend these funds.

Personally I’m not rooting for ChargePoint over Car Charging Group, or for EVGo over Greenlots, etc. I believe the market will sort that out, and eventually the stronger networks which provide the best equipment and customer service will emerge as the dominant forces. However, the enormity of this settlement could have the opposite effect, and allow VW to crush the competition before the natural evolution and survival of the fittest has time to take effect. If the stronger companies of today aren’t even allowed to bid on projects funded by this penalty, they could end up dying before they have the chance to flourish and provide the marketplace with superior products and services.

I’d like to see an independent council appointed to oversee the infrastructure fund implementation, so as to not skew the marketplace. There should be appointees from various industry stakeholders, EV advocacy groups, like Plug in America, The Sierra Club, Clean Cities Coalitions, etc. Let the council decide how the money is spent and always offer open, competitive bidding taking in consideration more factors than simply the lowest bid. The council will be much more effective than Volkswagen could ever be, and we'll probably get more robust equipment and better customer service as a result.

Volkswagen should not have near complete control over the money they were fined. They’ve proven beyond any reasonable doubt that they cannot be trusted when it comes to clean air initiatives. There’s too much at stake here. We have an opportunity to really advance the proliferation of electric vehicle charging infrastructure in the US, and provide the industry with a much-needed boost. This settlement should be modified to allow competitive bidding for all projects, to follow a master plan for national electric vehicle DC fast charging, and to add proper oversight and transparency.

BMW i3 Life Hack: Charge Port Snow Cover

Charging in the snow can be problematic when the charge port ices up and won't close
Charge ports on electric cars are similar to the fuel tank filler openings on gasoline and diesel cars in that the fuel or energy is transferred into the vehicle through an opening that is typically concealed by a small door or flap. However, since electric vehicles take much longer to recharge than conventionally powered vehicles take to refuel, the charge port is open much longer than a fuel filler door would be. While a gasoline stop may mean the filler door is open for two or three minutes, an EV's charge port will likely be open for many hours, and even all night long. In adverse weather conditions that may cause problems.

I'm just about through my second winter with my i3. This winter hasn't been too bad, as it has only snowed a couple times here in Northern New Jersey. Last winter was much worse and we had about a dozen snowfalls. Most of my charging is done at home, with my car nestled safely in a heated garage, so it isn't exposed to the elements while charging. However I also charge at work when I need to, and that's outside in the parking lot of my restaurant. So I do have plenty of experience charging outside in inclement weather.

My charge port was iced up after a recent snowfall and I had trouble getting the charge port door to close.
One thing I've noticed on my i3 is the charge port locking mechanism can get jammed by snow or ice, and refuse to allow the charge port door to stay closed. It's not a monumental issue, since the i3 also has rubber caps to seal the J1772 and CCS inlets so even if you can't close the door, the charge port is safe from water damage. Still, I view this as a problem since I've had it happen a couple of times and other i3 owners have reported experiencing the same issue.

"This is just so extremely bad design! That snow must be removed completely and there are all kinds of tiny areas almost impossible to get to. Cleaned a bit too sloppy the other day, and barely was able to open it again. Why on earth did they not create something better?" 
- BMW i3 owner Are Stig Larsen, Norway.

I wonder if BMW just missed this, and designed the charge port as if it was going to be used like the fuel filler ports are on their gas and diesel cars? It's particularly strange because I never had this issue on my previous EVs, which were also made by BMW (MINI-E and ActiveE). Since charge ports for electric vehicles will be open for many hours every day and exposed to all kinds of weather, I think a higher level of thought must be applied to their design. Based on the issues I've seen, I'm just not sure that was the case with the charge port for i3. To be fair, a simple internet search will reveal owners of Chevy Volts, Teslas and Nissan LEAFs lodging similar complaints, so it's not exclusively a BMW problem. The question is, should we really have to deal with this, or can EV engineers figure out a way to solve the problem without adding too much cost to he vehicle?
A few people have used the cardboard technique as their solution. Photo credit: Are Stig Larsen
Necessity is indeed the mother of invention, and I've seen various i3 owners come up with a couple of different ways to attempt to solve the problem. One person tried using a plastic shower cap with marginal success. There have also been a few cardboard cut outs used, and I think they worked pretty well. The problem is the cardboard gets ruined by the moisture and can only be used a couple times before needing to be replaced.  However there is one solution which seems to be gaining traction as the go-to life hack for this issue, and that involves using an insulated outdoor faucet cover.

Outdoor faucet covers are made to help protect an outdoor hose valve from freezing. They are typically made of styrofoam and have a plastic draw string which latches onto the spigot to keep the cover from blowing away. The higher quality covers have a plastic outer shell with a styrofoam lining on the inside. One such cover is available at Lowe's Home Improvement stores for $2.98. It's made by Creative Plastic Concepts and is a near perfect fit for the i3's charge port opening, making it an excellent choice. You'll want to get one with the hard plastic shell, like this one. The styrofoam covers don't last as long because once you cut them to make an opening for the connector, they tend to gradually crumble and break apart where you made the cut. The covers with a plastic shell are only $1.00 more than the all-styrofoam, and it's a dollar well spent.


Creative Plastic Concepts has two different models available at Lowe's. The hard plastic one is more durable and a better choice for this use. The good news is it only costs $2.98! Similar covers are also available on Amazon.
The only modification necessary is to cut out an opening for the charging connector. To do so you'll need an X-Acto knife, or similar utility knife. The opening must be cut on one of the wider sides of the cover (it's rectangular, not square) and needs to be at least 2 1/2" wide to accommodate different sized J1772 connectors. I cut mine 3" inches wide, to make sure CCS (Combo) connectors would also fit without issue. Make sure you cut the opening just about all the way to the top of the cover, and I'll explain why this is necessary later.

The loop holds the cover in place
The cover fits so snugly it will stay in place by itself under most instances. However in windy conditions, it may blow off but there are two methods to prevent this. First, the plastic draw string which was meant to hold the cover on the faucet can be used to hold the cover on the J1772 connector. Loop the end of the string onto the top of the release button on the connector and pull it through the top until it's tight. There is a small spring loaded locking mechanism on top of the cover which holds the plastic cord in place. The one problem with this is that not all J1772 connectors have the same type of release button. Some just won't accommodate the plastic loop that holds the cover in place.

My answer to this is to simply carry a rubber band with you, and use it to hold the cover in place. This eliminates the potential problem of arriving at a public charging station which uses a connector that won't allow you to loop the plastic draw cord around the release button.  Since I use this method, I no longer needed the plastic draw cord, so I removed it and in its place attached a kitchen cabinet knob which I had left over from my last kitchen renovation. I know a few people who use the plastic loop cord that comes with the cover without problem, but they haven't come across an EVSE with a release button that won't cooperate, but eventually they will.
A rubber band will secure the cover from blowing off and will work with any type of connector. The supplied plastic draw string won't work with some J1772 connectors. 
It only costs you $2.98 if your cover blows away, but it's the hassle of having to buy another one and cut the opening if it does. For that reason alone, I think it's a good idea to make sure you have a few rubber bands handy when you plan to use the charge port cover.



I gave my cover a paint job and came pretty close to matching the color of the red wrap that I have. The cover's stock drab tan color just didn't do it for me so I splurged for another $3.99 and picked up a can of spray paint.  So for under $10 I've solved the problem, and stylishly I might add! I think this is something BMW needs to take a closer look at, and perhaps rethink. Maybe a heated locking mechanism or a redesign that better prevents this icing up issue. This is just another example of how the engineers need to really rethink everything when they design an electric vehicle. The user interaction with an EV's charge port is much different than interaction an ICE owner has with their fuel port. This is just another example of how OEMs can benefit from tapping into the knowledge of existing EV owners through focus groups and surveys. I've long been advocating these methods to help the manufacturers make better EVs.
The finished product. I even found a BMW i Frozen Blue color rubber band. It's pretty amazing how well this cover fits the i3's charge port opening. It's almost as if it were designed purposely for this application.
Until they come up with a redesign or some other solution, I think BMW should make something like this and sell it alongside the other BMW i accessories that they offer. I'm sure i3 owners wouldn't mind spending $20 - $30 for an item like this which can save them a lot of aggravation, especially if they live in a cold weather region. BMW could probably just get Creative Plastic Concepts to modify and make it for them. BMW can then slap a BMW i logo on it, and they have a workable solution until a permanent modification is in place.

I mentioned above that it's important to cut the opening all the way up to the top of the cover and I'd explain why later. The reason is because not all J1772 connectors are created equal. If the top part of the connector is long, it will stick up higher when connected to the car. This requires a longer opening than connectors which have shorter ends. Take a look at the pictures below and compare the ChargePoint Home connector to the ITT J1772 connector used by Bosch on their Power Max 2 EVSE. You can see how much longer the connector is and if you don't extend the opening on the cover all the way to the top the longer connectors won't fit, and they'll push the cover away from the car. You can also see from the pictures how some release buttons won't work with the cover's plastic loop system to hold it in place, requiring the use of the rubber band method.

BMW EV Infrastructure Discussions from the LA Auto Show: Part 1


A few weeks ago at the LA Auto Show, BMW made news by announcing a partnership with NRG's EVgo to install an additional 500 DC Fast Charge stations in 25 major US markets. The project is called the ChergeNow DC Fast and is actually the second phase of a program started in 2014, which brought 100 DC fast charge stations to select California areas. I was there at the show for Press Preview days, and had the opportunity to sit down with basically all of the top EV infrastructure managers at BMW of North America. Seated at the table were Robert Healey, Electric Vehicle Infrastructure Manager, Idine Ghoreishian, Electric Vehicle Infrastructure Specialist, and Cliff Fietzek, Manager of Connected eMobility.

Even though the news of the ChargeNow DC Fast program had just been released, I wanted to first talk about the East and West Coast Express Charging Corridors. If you remember, this program was announced back in January at NAIAS and the press release stated that approximately 100 stations would be installed in these corridors (Washington, DC to Boston, MA on the East Coast, and San Diego, CA, to Portland, OR, on the West Coast) and it would be completed by the end of 2015. This was a joint venture between BMW, Volkswagen and ChargePoint. ChargePoint is responsible for the installations, and BMW and VW are basically telling them where they want them, and footing the vast majority of the bill. Time is running out and I knew they wouldn't hit the predicted deadline, so I asked the group what happened, and when can we expect it to be done. Here are some quotes from the discussion:
Rob Healey, BMW's top EV infrastructure manager

When asked about why they missed the predicted end of 2015 completion date, Fietzek said: "The business model for ChargePoint changed for this program. Before this they were responding to site hosts that wanted to have a charger installed. Basically the site host would call them, and say they wanted a charger. Now, ChargePoint had to go out and say to property owners, 'I need to put a charger here, because BMW and Volkswagen want me to, do you want to work with us?' This was very different from what they were accustomed to."

Ghoreishian added: "Another challenge of placement goes back to our goal of making sure they were no more than 50 miles apart. Seventy five miles just won't work."

I also learned that getting the sites in good locations was more important than just getting them in the ground and meeting a deadline. BMW knew these locations would likely be used for years to come, so it would be worth their while to take the time to make sure they got good locations. In that vein, Healey had this to say: "There is a process in place between BMW and VW; collectively we have the final (site) approval. There were a lot of sites offered to us that we rejected. For instance, we looked at the customer and said, 'Do you want to have your wife go in and charge in this area late at night?' There were sites that we rejected because we didn't think it was a safe place. We want the best sites for our customers, basically."

I then asked if they thought BMW should finish this program before they start new infrastructure projects, like the NRG EVgo program which had just been announced and Fietzek quickly said: "Different partners, different projects. I'd rather have them running in parallel than waiting for one to finish before starting another. We'll get things done much faster this way."

Finally, I asked that since it's clear the program won't be finished on time, when can we expect the two Express Charging Corridors to be completed, and Healey answered: "Yeah, we're a little delayed. We're now shooting for early spring for completion. We always knew it was going to be tight. We sat with ChargePoint, we talked to the Volkswagen people and said, 'Can we do this in one year?' We knew approximately where we wanted to install the stations, but we still needed to contact the property owners, sign site host agreements, go through permitting and that just took more time than we expected. If you look at the ramp up, we started off slow, but are now really ramping up. We should have about 52 stations active by then end of the year, with another 19 already under construction. We're looking at finishing in late March or April."

Having personally gone through the process of installing a DC fast charger on my property in Montclair, NJ, I know the challenges that can arise during the process. I'll actually be pretty impressed if they do finish by Spring. That would mean that they installed the 100 stations on two coasts in about 15 months, and the company doing all of the site host agreements, permitting and installations never really took on a project like this before. That's really not bad in my opinion.

With that progress update on the East and West Coast Express Charging Corridors finished, I turned the discussion to the announcement made just hours before, the national ChargeNow DC Fast expansion. This is actually an expansion of a program started in 2014, when BMW and NRG teamed up to install 100 DC Fast chargers to select California markets. That program was completed earlier this year, and this is the second phase. There will be an additional 500 DC Fast chargers installed in 25 markets around the country.

When I asked about why they chose these specific markets, Healey said, "One of the important points of the expansion of the NRG program is that these 25 markets cover 80% of our current i3 sales. Now, we don't want to forget about the other 20% of our customers; we're working on it, and you'll be hearing from us shortly about how we're filling in the other 20%. It's really a systematic approach."

The 25 markets covered in this second phase of the program are:
 
Atlanta, GA; Austin, TX; Boston, MA; Chicago, IL; Dallas, TX; Denver, CO; Fresno, CA; Houston, TX; Los Angeles, CA; Miami, FL; Monterey, CA; Nashville, TN; New York, NY; Orlando, FL; Philadelphia, PA; Phoenix, AZ; Portland, OR; Raleigh, NC; Sacramento, CA; Salt Lake City, UT; San Diego, CA; San Francisco, CA; Santa Barbara, CA; Seattle, WA and Washington, DC.

Arun Banskota, President and CEO of NRG's EVgo had this to say about the program:

“It is our mission to install the right charging solutions at the right places, and EV drivers have overwhelmingly told us they prefer DC Fast chargers at public spaces. Over the next 24 months EVgo will add reliable DC Fast Combo capability to what is already America’s largest DC Fast charging network. This will be the fastest and most cost effective build out of a new network ever – thanks in large part to our existing infrastructure and committed retail host partners... The only way such a massive expansion is possible is because of the purpose built, and forward looking planning behind the EVgo network...EVgo has installed infrastructure with the ability to efficiently and economically add this new DC Fast Combo standard as the number of electric vehicles have increased. EVgo owns and operates our chargers with long term agreements with premium retail hosts, and is able to provide the level of customer service, reliability, and pricing that will lead to increased EV adoption and high satisfaction among the existing base of EV drivers.”

The deployment rate of these 500 stations is expected to be aggressive. NRG is a very large company with vast resources and plenty of experience with regards to installing infrastructure. After all, they are an electric utility company. Healey told me that they have existing sites that currently have CHAdeMO stations that they'll be adding a Combo (CCS) station to, as well as many other sites already identified and ready to go. He expects to see hundreds of stations completed within the first year and the entire 500 stations in the ground and operational by the end of 2018. He even said that he's being conservative with these predictions based on the lessons learned by the previous programs they worked on, and that it is quite possible that they finish earlier than the mid 2018 prediction.

Since I had over an hour with the team, we covered a lot of infrastructure topics and there's just too much for one post. Check back next week for part two when the discussion turns to BMW's decision to offer free charging, but only for new i3 buyers, the future of DC charging and BMW's long term commitment to EV infrastructure.

First Public CCS DC Fast Charger in New Jersey Getting Action

This CCS DC Quick Charge station is located on my property at 148 Valley Road, Montclair, NJ
Back in August I posted an article that announced the opening of the first DC fast charger in the East Coast Express Charging Corridor. That station was installed in Hartford, Connecticut. The Express Charging Corridor when completed will connect Washington, DC to Boston, Massachusetts with CCS DC fast chargers, located no more than 50 miles apart, and is being funded by a joint venture between BMW, Volkswagen and ChargePoint.

About three weeks after the station in Hartford was installed, I installed one on my property in Montclair, NJ. It was the first public CCS station in the state that wasn't installed on BMW property. BMW has had a few CCS fast chargers at their North American headquarters for a few years now, as they have been testing CCS since 2012, when they were using a modified BMW ActiveE with CCS capability as a test mule for the then yet-to-be-released i3.
So far the DCQC station is getting plenty of use from i3 owners
CCS fast charge infrastructure had a slow start, frustrating many i3 owners. It was difficult to watch the Asian standard CHAdeMO stations and Tesla Superchargers continue to proliferate, while CCS stations were as rare as White Rhinos. However the pace of CCS deployment has really picked up, and with the East and West Coast Express Charging Corridors beginning to take shape, it's starting to look like CCS is finally getting some traction.

The station I installed is the smaller of the two that will be used in these corridors. I have the 24kW, CCS only DC fast charger but there is another unit that will also be deployed on many of the direct highway locations. That unit is a dual head, CCS and CHAdeMO station and is capable of delivering up to 50kW. Because of the location on my property (not situated on a highway), and the primary tenant is a restaurant where people typically spend an hour or more, the 24kW unit made more sense, and it costs a LOT less. The lower power draw will also help me to avoid or minimize demand charges from my electric provider.
The eGolf owners were very pleased when they realized the DCQC in my lot was close to the route they planned to take to Massachusetts. They only had to drive a few miles off of their route to stop by and Quick Charge
I installed the station a little over two months ago and it's definitely getting use. I've had at least a couple dozen different i3 owners stop by and use it, and I recently had an eGolf owner who was driving from Delaware to Massachusetts stop by to charge up. I was talking to them about the trip and how long it would take to stop and charge at level 2 stations and how happy there were when they saw my DCQC station pop up on the Plugshare map.

Fast charge infrastructure is monumentally important for the mass adoption of plug in cars. Tesla knew the success of the Model S, and probably even the entire company, would hinge on how quickly they could cover large swaths of the US and other key markets with Supercharger access. They have been installing them at an incredible rate, and have installed more than 500 worldwide in under 3 years.

Nissan has also done their fair share with regards to DC fast charge infrastructure and has subsidized much of the costs of hundreds of CHAdeMO installations. Personally, I'm hoping Volkswagen steps up and commits to installing even more infrastructure than the current plan in light of the current dieselgate scandal. Making a commitment to assisting the proliferation of cleaner electric cars would be a good first step in restoring public confidence at this point.

We are getting there. EV charging infrastructure, both level 2 and DC fast charge, is still really in its infancy, but we're definitely making progress in some areas of the country (mainly the coasts). I remember back to 2009 when I was driving my MINI-E and there wasn't a public charging station within a thousand miles of me. In fact, the closest one may have even been 3,000 miles away in California.  Now there are tens of thousands of them in the US. I can only imagine how things will look in another five or six years.

The Plugshare map on the left shows only CCS DC Fast charge stations on the East Coast. Just a year ago at this time there were none in this view. Within a couple of months, there will be dozens more of them as the Express Charging Corridor locations are finished. The large gap south of my restaurant (the blue dot) will hopefully be closed by year's end. The pace of CCS deployment is definitely picking up, and I believe will only continue to accelerate from here on.

ChargePoint Home: Connected EV Charging with Style

The ChargePoint Home 25 EVSE is the latest addition to my EVSE collection
When most electric vehicle owners think of ChargePoint, they likely are thinking about public charging infrastructure. That's because for the past five years, ChargePoint's focus has been on installing and maintaining the largest network of public EVSEs in the US, with well over 20,000 locations currently in use.

Back in 2012, ChargePoint did release an EVSE for home charging, the CT500 made by Coulomb Technologies, but it was priced a bit above the market at $2,495. At the time, it was the only home EVSE that was networked, so that was a major advantage. However, the price was prohibitively high and competitive units were selling for half of that, so the CT500 never sold in any serious volume.

That won't be the case with ChargePoint Home, ChargePoint's new entry in the home EVSE market. I've had the opportunity to test this product for a month now, before the official launch and I've been really impressed.
Options

There are two power levels offered, a 16 amp unit (The ChargePoint Home 12) and one which can deliver up to 32 amps (The ChargePoint Home 25). If you're wondering why "12" and "25" are used in the product names it is because ChargePoint is advertising that the 16 amp unit is capable of adding 12 miles of range per hour to the typical EV, and 25 miles of range per hour for the 32 amp unit. I'm not particularly fond of using that method to name them, since every EV is capable of achieving different levels of efficiency. Plus, I think it may confuse some people who think the number is the amps the EVSE is capable delivering. However, this is only the name so it's not really a big consideration.

Since I'm discussing the power delivery, this brings me to one of the few criticism I have for the new ChargePoint Home. While 32 amps is above the maximum charging limit for any currently-offered electric vehicle that isn't a Tesla or that uses a Tesla onboard charger (Mercedes B-Class ED), some of the competition is now offering 40 amp and 50 amp home charging solutions. These would be attractive for Tesla owners, and perhaps someone who wanted to future-proof their garage. I suspect ChargePoint would be ready to offer a higher powered version in the future if there are any new electric vehicles offered that can accept more than 32 amps. However, considering the current electric vehicle offerings, 32 amps is fine.

I got the optional 25' cord
After selecting whether you want the 16 amp or 32 amp EVSE, you then have the option of choosing a hard wired unit or one that plugs in. The 16 amp plug-in version uses a NEMA 6-20 outlet and the 32 amp plug-in EVSE uses a NEMA 6-50 outlet. Once that is decided you can choose the length of cable you want, but that's only if you buy the 32 amp version. For some reason, the 16 amp version only comes with a 12' cord, you cannot order it with one longer. That could be a deal breaker for some people whose garage is set up in a way that twelve feet of cable won't reach their charge port. On the other hand, the 32 amp unit comes standard with an 18' cord, and has an optional 25' cord for an additional $50. It's a bit puzzling why the lower powered unit isn't available with a longer cord, and I believe this will steer many potential customers to the higher powered EVSE, even if they originally considered the lower powered unit (maybe that's the plan!).  I did reach out to ChargePoint about this and was told that a customer can order a replacement cord of either 18' or 25' length and replace the 12' standard cord that comes with the 16 amp EVSE. I didn't get the pricing, but I assume it will cost considerably more than the $50 up-charge when you upgrade from an 18' cord to the 25'cord on a ChargePoint Home 25 (32 amp). The rep also told me that if there is demand for longer cords on the 16 amp unit, then ChargePoint will consider offering it at a later date.

Installation

Drill bit & nut driver
If you choose to go with one of the plug-in versions, you'll need to have an electrician install the appropriate outlet in your garage. The 16 amp unit requires a 20 amp, 240v dedicated circuit with a  NEMA 6-20 outlet and the 32 amp EVSE requires a 40 amp circuit with a NEMA 6-50 outlet. I chose the 32 amp hard wired one, with a 25 foot cord. Since I was replacing one of my older EVSEs with the Home unit, it was an extremely simple process, and that wasn't by accident. ChargePoint made every effort to make installing the Home EVSE as easy as possible, especially if the owner was swapping out an older EVSE for the new Home unit. In that case, it's so easy to do that the average person can probably complete the installation in less than an hour. I had mine installed in about 30 minutes. A drill bit and nut driver for the supplied wall mounting screws are even included. One aspect of the installation I found curious is that all three mounting screws run down the center of the unit, as opposed to the four corners. This could possibly cause the EVSE to rock a bit from side to side if the wall it's mounted on isn't flat. I'd prefer if the mounting screws were in the four corners, which would provide for a more secure mount on uneven surfaces.

Another great feature is how compact, lightweight and portable the ChargePoint Home is. At only 11.2" by 7" it's stylish and not bulky. It has a back-lit connector holster which swivels up and down and that helps to make returning the connector to the base easy, even in the dark. If you choose the plug in version, you can easily take this EVSE with you for charging away from home. All you would need is the appropriate outlet at your destination. The ChargePoint Home is indoor and outdoor rated and is UL listed.




















The ChargePoint app displays useful charging information such as current and cumulative energy draw. You can also set a "Remind Me to Plug in" notification, so you never wake up to an uncharged EV.

Perhaps the best feature of ChargePoint Home is that it can be integrated with your ChargePoint account which allows the user access to information from the ChargePoint mobile app. This includes viewing information on the current charging session, remotely start and schedule charging, set notification reminders so you don't forget to plug in, review data on past charging sessions, and it even works with Nest thermostat products which can help save energy.

ChargePoint Home EVSE pricing starts at $499 for the Home 12 hard wired station and goes up to $749 for the Home 25 plug in station with a 25 foot cord. Full pricing details are below. ChargePoint Home has a three year warranty and is available through Amazon.

ChargePoint Home 12: 16A Hardwire station with 12' cord$499
ChargePoint Home 12: 16A Plug station with 12' cord$549
ChargePoint Home 25: 32A Hardwire station with 18' cord$649
ChargePoint Home 25: 32A Plug station with 18' cord$699
ChargePoint Home 25: 32A Hardwire station with 25' cord$699
ChargePoint Home 25: 32A Plug station with 25' cord$749
Slim, compact design


I've been using my ChargePoint Home 25 for a few weeks now and I really like it. ChargePoint has a winner with this EVSE, and I predict it will sell very well. I've been driving electric for over six years now, and I've seen the evolution of EVSE products. It's good to see the products continue to improve just as the prices continue to go down. The ChargePoint Home delivers on size, portability, quality and ease of installation. It's stylish, competitively priced, and best of all connected to the ChargePoint Network which allows the user mobile access to effective tools which can enhance their electric lifestyle. This all adds up to great news for EV owners.



Note: I received for free, one ChargePoint Home 25 EVSE from ChargePoint for testing, feedback and product review publication before the consumer launch. No other compensation was made.

First DCQC Unit in the East Coast Express Charging Corridor Installed

An i3 sits next to a 24kW DC Fast Charge unit during the announcement of the BMW, VW & ChargePoint joint venture earlier this year. 
It's been seven months since BMW, along with Volkswagen and ChargePoint announced a joint venture which would install roughly 100 DC fast charge units on the East and West coasts. While there's been a lot of work identifying potential locations and negotiating with site managers, there hasn't really been any tangible progress that electric vehicle owners could see.  

The plan is to create "Express Charging Corridors" on both coasts, with DC Fast Charge stations placed no more than 50 miles apart. The East Coast Corridor will connect Washington DC to Boston, Massachusetts and the West Coast Corridor would extend from San Diego, California to Portland, Oregon.  There would be two kinds of DC Fast Charge stations utilized. The stations placed directly on the highway locations of the corridors would be 50kW units, most of which will be dual head CCS & CHAdeMO stations. Then, on secondary locations slightly off the direct corridors, 24kW CCS-only units will be placed. While these 24kW units aren't necessarily quite fast enough to be convenient for long distance travel of hundreds of miles, they are very useful for intercity travel and charge at three to four times the speed of standard level 2 public charging.
ChargePoint's East and West Coast Express Charging Corridor Infographic
I applied, and was recently approved under the program guidelines to have one of the 24kW units installed on my commercial property in Montclair New Jersey.  I'm currently awaiting the permits to be approved and hope to have the station installed and working before my National Drive Electric Week event on September 12th. Always the competitor, I was also hoping to be the first East Coast public location in the program to get a station installed, but I'm actually happy to report that won't be the case. That's because a friend of mine and fellow BMW i3 owner, Bruce Redman Becker has beaten me to it. Bruce, and architect and developer, is responsible for 777 Main Street in Hartford Connecticut, a newly developed 285 unit apartment building with a 250 car parking garage. In describing the location to me, Bruce had this to say:

"The site is just two blocks from exits off I-91 and off I-84.  We have one SAE combo DC fast charger and 10 level 2 chargers (3 duals in the surface lot and 2 duals up the ramp within the covered garage).  Power  for all 11 Chargepoint chargers comes from a 400kw fuel cell adjacent to the chargers that also provides renewable clean energy to heat and power the apartment tower….We have three coffee shops on our block, including a Blue State Coffee on the first floor of 777 Main opening in September.  And there are over a dozen great restaurants nearby as well as a great camera shop, CVS, banks and the Hartford Atheneum museum to enjoy while charging."

So while none of the main corridor, 50kW units have been installed yet, it seems the secondary, 24kW stations are beginning to materialize here on the East Coast, which is welcome news. I know some i3 owners have been frustrated by the seemingly lack of action with regards to the DC Fast Charge roll out, but I also know first hand that BMW and ChargePoint have been working very hard to locate potential locations, negotiate site agreements and collect bids for the installation. They've been at it for half a year now and I believe we're going to begin to see some real progress made in the next couple months. Getting the first one up and running can sometime seem like the biggest hurdle in programs like this. Well, now that that's done I'm optimistic that in the next six months we'll see dramatic progress made on both coasts. 
Three 24kW DCFC units have been up and running at BMW Headquarters in Woodcliff Lake, NJ since January. They are open to the public and free to use.

Featured EV Product: The JuiceBox Pro 40 EVSE

The latest addition to my EVSE obsession collection is the JuiceBox Pro 40, seen here charging my i3

One of the first things many first time electric car owners ask once they've bought (or are about to buy) their new car is what home charging solution should they choose. Other than asking for advice on specific plug-in cars, it's the most popular question I get from readers here.

Luckily, there are some really good choices on the market now, and the prices for home EVSEs are considerably less than they were when I first started driving electric in 2009. Back then, the only level 2 home EVSEs that I would recommend were from Clipper Creek. Clipper Creek still makes very good products, and I still recommend them, but the competition is getting better all of the time, and one company in particular, eMotorWerks has been gaining momentum in this competitive market.

Before I get into the review, I'd first like to explain some basic EV charging levels and terminology. This applies to charging in North America, as electric supply is different for most European countries.

EVSE: Electric Vehicle Supply Equipment. These are quite often called "chargers" or "charging stations." That really isn't the correct terminology though,  because they don't actually charge the car. They really just safely supply the electricity from the power source to the vehicle. The actual charging equipment is built into the electric cars. Some EVSEs are portable, while others are hard wired and permanently installed.

Level 1: Every electric car sold or leased in the US that isn't a Tesla comes with a Level 1 portable EVSE. Some manufacturers, like BMW, call it an "occasional use charger." Level 1 EVSEs can be plugged into a simple 120 volt household outlet and typically charge at 6, 8 or 12 amps. Tesla doesn't bother with Level 1, 120 volt EVSEs because their vehicles have such large batteries that they would take very long to slow charge on 120 volts. For that reason, every Tesla comes standard with a portable 240 volt EVSE for more robust charging at home or on the road.

Level 2: Level 2 EVSEs charge at 240 volts and most of the time are permanently installed in a garage or public parking lot. However, recently some manufacturers have been selling portable 240 volt EVSEs, allowing the owner the flexibility of using the equipment at home as well as on the road, provided they can find a 240 volt outlet that they can plug into. The JuiceBox Pro 40 which I'll be reviewing here today is one of those newer units, and comes with a NEMA 14-50 plug instead of requiring the owner to hard wire it to their home.

DCQC / DCFC: DC Quick Charge or DC Fast Charge. DC fast charge allows rapid charging of electric vehicles, enabling long distance travel with little inconvenience. DC Quick Charge stations can charge many EVs up to 80% full in about 30 minutes, but are not something an individual would buy for home use because of the cost and required 480 volt electric supply. These units are very expensive and are only just beginning to really proliferate. Unlike Level 1 and 2 charging, there are multiple connectors used by different manufacturers, as a single standard hasn't been established yet.

Some people live fine with their EV, charging solely with the supplied 120 volt portable EVSE. However most owners will prefer using a 240 volt EVSE, so that they can charge much faster, enabling the vehicle to be driven more miles if needed. For example, a basic 120 volt EVSE will replenish about 4 to 5 miles of range per hour, while a standard, 30 amp 240 volt unit will add 20 to 30 miles of range per hour to the typical EV. That can make the difference of being able to use the car or not on some days.

JuiceBox Pro 40 EVSE
I think I've charged my EVs on every brand of EVSE on the market today, and I have a host of EVSEs in the garage at my house which I use for various testing and when I have visitors that also have cars that plug in. I had been reading a lot about how eMotorWerks has been expanding lately, and how they recently sold their 3,500th JuiceBox EVSE. So when the opportunity came for me to test out the latest offering from eMotorWerks, the JuiceBox Pro 40, I happily accepted. I want to make it clear I did receive the EVSE free of charge, however I wasn't paid to do the review, and there were no conditions or promises on what I would write. In other words, if I didn't like it, I would say so, or perhaps not even write a review.


First, I'd like to point out the JuiceBox Pro 40 can deliver up to 40 amps of power. The vast majority of Level 2 EVSEs currently on the market are limited to delivering 30 amps of power. There are a few other companies like Clipper Creek for instance, that do offer a 40 amp EVSE, but for the most part, the industry norm is 30 amps and even less in many cases. When buying any EVSE, make sure you find out what the maximum power the unit can deliver before purchasing it. I know more than one EV owner who bought an EVSE and didn't know it could only deliver 16 or 20 amps until they installed it. Why does 40 amps matter as compared to 30 amps? Well, for most EVs today, it doesn't. Only Tesla makes on board charging equipment that can accept more than 30 amps from a level 2 source, however that is going to change. I like to recommend future-proofing your garage, and if you're investing in a home charging solution which you may be using for ten or more years, why limit the charging supply to today's norm when home charging will only get faster as EV adoption increases? If your home has the capacity to add a dedicated 50 amp circuit (a 50 amp circuit is required for a continuous 40 amp load), then I say pay the few extra dollars today so you don't have to go back and upgrade in the future.

The feature I love the most about the JuiceBox Pro 40 is that is has built in WiFi and connects to eMotorWerks servers. This allows for real time charging monitoring which includes voltage and current measurement accurate to 0.2%. This is the only EVSE I know of currently available which allows you to monitor this kind of charging data. I know a lot of EV owners, and one of the things that keeps coming up is people asking how they can find out what the car is drawing during charging. ChargePoint allows the current measurement to be viewed on their app if you are charging on one of their networked EVSEs, and they used to offer a home EVSE (CT-500) which allowed the same, but that has been discontinued. Having the ability to monitor your vehicle's electric draw is particularly useful to BMW i3 owners like myself. The original i3s shipped with faulty onboard chargers, causing many of them to fail. This resulted in the car charging at half the speed than it was supposed to (15 amps instead of 30 amps). To make matters worse, while BMW engineered a new onboard charger, the dealers were instructed to de-rate the i3's current charging capabilities to about 24 amps, in an effort to keep the charger from failing. Many i3 owners didn't know if their car was de-rated, if their charger had failed or if they were charging at the full 30 amp rate. Without a way to really measure the energy the car was accepting, many were left in the dark for a few months while BMW built and installed the new, modified onboard chargers. If they had an EVSE that had the capability of displaying the rate the car was charging at, they would never have to wonder what the car was capable of drawing since they could simply look at the app when they plugged in.


If you're wondering if you can mount and use the JuiceBox outdoors, this video demonstration should satisfy any concern you have.  

The connector has a cover
As mentioned above, the JuiceBox Pro 40 doesn't need to be hardwired. Instead, it comes with a NEMA 14-50 connector. This allows the owner to take the EVSE with them, all they need to do is find a NEMA 14-50 receptacle and they can plug in. The 14-50 outlet is commonly used by RVs and thousands of RV parks across the country have 14-50 receptacles where you can plug in on the road if needed. But in my opinion, the real beauty of having a portable, plug-in EVSE is you can install 14-50 receptacles in places like your parents or friends home, or even work, and take the EVSE with you and charge at your destination. This is much less expensive than installing EVSEs in locations you may need to occasionally charge at. The JuiceBox is small and light enough to take with you when needed. You can see this on the photo above compared to the other EVSEs I have mounted on my garage wall. The connector also has a rubber cap if you do mount or use it outdoors.

The app is very easy to set up, and should take you less than ten minutes to complete. There is also a web portal which you can log into for past history charging info (it stores data from your last 20 charging sessions) and soon you'll be able to set up notifications from the site. eMotorWerks also offers 60 amp, as well as 30 amp EVSEs, with and without WiFi connectivity. The JuiceBox Pro 40 with WiFi currently costs $599.00 which is $100 more than the basic JuiceBox 40. Personally, the WiFi feature is well worth the upcharge and I highly recommend getting it. You'll really appreciate the ability to look at your past charging sessions and energy consumption and it definitely helps you to see exactly how much energy your EV car uses because you'll have a true "wall to wheels" measurement, which includes charging losses. The in-car energy use calculators don't include charging losses or the energy used from battery or cabin preconditioning while charging, but this does. The difference can be significant, especially during the winter months when the battery may needs to be warmed while charging. The JuiceBox Pro 40 comes with a 24 foot cable which is a little longer than most standard EVSE cables. The extra few feet of cable can make the difference of having to back into your garage or pull straight in, and possibly allow you to park on either side of the garage in any position and still have enough cable to plug in.  
Don't let the plain, metal box look fool you. This is a seriously good EVSE
The EVSE market is getting better all the time. The products available today are more powerful, lighter,  some are portable and overall less expensive than the products available only a few years ago, and this is welcome news to EV owners. eMotor Werks is a relative new comer to the field of EVSE manufacturers, which is mostly dominated by larger, well established companies. However, the people there seem to understand what the EV owner is looking for in an EVSE, and they have delivered it with the JuiceBox Pro 40, which is why I recommend it. The price is right, the size is right, it's powerful and portable. About the only thing you can criticize is the plain-looking metal case which houses the electronics. If that really bothers you, you can always paint it, or apply a vinyl wrap or sticker to add some pizzazz. :)

i3 Owner Explains Her 312 Mile All Electric Day

Kris charging up at an NRG Fast Charge station
One of the many things that Tesla Motors understands as well as anybody is how a robust Fast Charge network will liberate their customers from being on an "Electric Leash." Ubiquitous DC fast charging stations are, in my opinion, just as important as longer range electric vehicles. In fact, they may even be more important.

BMW apparently shares that opinion and has recently announced that they are getting into the DC fast charge game with a partnership that includes Volkswagen and ChargePoint, and will be installing fast chargers at 50 mile intervals on the East and West coasts to create "Express Charging Corridors." However it won't end with there. BMW is going to continue to invest in DC fast charge infrastructure here in the US, as they realize that they need to participate in creating the foundation for BMW i to succeed.

As with most things EV-related, California is ahead of most of the US when it comes to DC fast charge infrastructure. While the SAE Combo (CCS) fast charge units are only beginning to be installed, there are some already in the ground there, and they are allowing people to take their i3s further in a shorter period of time than they could if they were relying on 240v Level 2 public charging.

Kris & I at a recent i3 meet
Which brings me to the story below that I found interesting.  My friend Kris Kluzak, a former ActiveE Electronaut, offered to write a guest post for this blog detailing a day when she drove her i3 312 miles using public charging infrastructure.  It shows that even a medium-range EV, like the i3, can easily cover hundreds of miles in a day if the appropriate infrastructure is in place.

Here's how it went down, in Kris's words:
 



A 312 mile, all electric day in a BMW i3 REx:

On November 11th, 2014 I was scheduled for a research study for my car in Sherman Oaks, California. From my house in East San Diego County, it is about 160-mile trip one-way.

On any given day this “normal” trip would take approximately 3-4+ hours in any vehicle with an engine (ICE) as the main power source. Those of us living in Southern California know the different routes to take to avoid traffic blunders, and are often looking for the carpool lane when it’s an option.

In order to arrive on time for my 2pm appointment, my husband and I had to build in a few charge/food stops; this set us to leave right after 8am. First, we stopped 39 miles away at the Carlsbad Premium Outlets to charge and grab coffee at Starbucks. *We charged for 30 minutes knowing we had enough range to reach our next stop in Santa Ana. 
 
Like me, Kris's previous electric car was a BMW ActiveE
We next stopped at Crevier BMW, 58 miles from Carlsbad. Just days prior they had installed four DCQC (SAE Combo) stations and we were on a mission to check them out. Normally we would not choose this route through Los Angeles, but since it was a Federal holiday we took advantage of the “lighter” traffic. We charged for an hour while our SOC (state of charge) reached 99%. While we didn’t plan to stay that long, we enjoyed talking to the "iGenius" in the new "iBuilding".  There was also a Starbucks and restroom on site for us to use.  We left there with our next intended stop in Sherman Oaks, not knowing for sure where we would charge, but would look once we got up there.  I was fully prepared to have my range extender kick in if needed, but I really was trying to do this trip without it.

We found that the local KIA dealership claimed to have an ABB charger, which is the same unit that NRG eVgo uses (yes, CHAdeMO and SAE Combo). We called to see if - 1) the charger exists, which it does, and 2) to see if we could charge, which we were told yes, to come on by.  It was a few miles from the Sherman Oaks location, so off we went.  The charger was blocked, but they immediately moved a car and allowed us to charge.  Unfortunately, the charger was so new, that it hadn’t been provisioned yet, and did not work.  At this point I had 22 miles of range, and 27 miles to the next, known Freedom Station in Hermosa Beach.  So we set off, knowing my range extender would probably kick in.

With some luck, and HEAVY Los Angeles traffic on the 405, we managed to get to Hermosa Beach with 6 miles to spare, and no REx usage.  I drove **83.3 miles on that one charge from Crevier. Once at Hermosa Beach, we managed to find the charger, a nearby bar offering Taco Tuesday, and managed to do all of this while just getting a 30 minute charge. Next stop, the Westminster Shopping Mall ***27 miles away.  We arrived at the mall with no range issues, and were able to charge again for just 30 minutes.  FroYo and a potty stop…and away to Carlsbad for the last stop.

We arrived in Carlsbad, once again hit the Starbucks and charged for only 20 minutes, enough charge to get home.  We were there about 30 minutes, but the charger faulted and stopped early.  We arrived home at just before 10pm.  312 total miles driven, all electric, no REx used, and all charges were free.  We spent a few dollars at Starbucks and for the dinner, but overall, did the whole trip for less than $50, all-inclusive.



Some key points to this trip:


I did not use any climate control until the last leg, there was no need for heating or cooling, but I had to run the defrosters a few times for the last 30 miles.

I ran the entire trip in Eco Pro driving mode.

I preconditioned the car that morning prior to leaving, hoping to warm the batteries before the trip for maximum range.

I purposely did not use the carpool lane. While this might have been necessary in another situation where time was an issue, I preferred to stay in the traffic in order to get maximum range. 

The total time spent portal to portal was 14 hours. I was at the research facility for almost 3 hours, and then we spent almost another 45 minutes to an hour at the Kia dealership talking to the manager about the charger, and looking at their Soul EVs.

Charging added 3 hours, which by using the DC quick charging options, made this a very reasonable trip.  If we had stopped in an ICE for breakfast and dinner, and potty stops, the total stoppage time would have been less, but not significantly, maybe an hour less, overall.

My Personal Records:

312 all electric miles in one day (previously 187 in my Active E, which did not have L3 charging)

83.3 all electric miles in one charge (previously 80 miles, in the summer, while hypermiling and drafting behind a truck for 20+ miles)

Cheapest day EVER to drive 312 miles, food and energy included.

*These outlets have two NRG eVgo charging options: level 2 and level 3. The level 2 option has one universal J1772 plug, and the level 3 option has a CHAdeMO (for Nissan Leaf’s, Kia Soul’s, and other Asian brand EVs) as well as a SAE combo (CCS) (for BMW’s, VW eGolf, etc.). This Freedom Station powered by NRG eVgo is part of free fast charging offered by BMW. 

**This car will definitely do better on range with slower speeds, ie: bumper-to-bumper traffic, and city stop-and-go vs full, freeway speeds.

***The mileage between Hermosa Beach and Carlsbad is 87.1 miles.  While we could have easily avoided a stop and used the REx, I would have been forced to charge longer at Hermosa to get a bigger charge, thus not saving any time AND using gasoline.
