Did The DC Quick-Charging 'Standards War' Just Quietly End For Electric Cars?

A BMW i3 and a Volkswagen e-Golf charge on DC fast chargers side by side at BMW Headquarters in Woodcliff Lake NJ.

I wrote this article for Green Car Reports, where it was published a few days ago. The proliferation of a robust DC fast charge network is vital to electric vehicle adoption, and I wanted to give this story as wide an audience as possible, which is way I let GCR publish it first. Now that they had it for a while, I'd like to share it with the readers here.

I was invited up to BMW NA headquarters by BMW product manager Jose Guerrero to try out the new DC fast chargers installed there. There are three of them, along with four Level 2 EVSEs, all of which are open to the public 24/7.

A couple weeks ago at the DC Auto Show, BMW, Volkswagen, and ChargePoint jointly announced they would install about 100 DC fast chargers for electric cars. Their goal is to create “Express Charging Corridors,” on both the East and West coasts, by the end of this year. The most intriguing news, however, was that the hardware will--in most cases--offer fast charging for electric cars using two different standards: CCS (used by BMW and VW) and CHAdeMO, used by Japanese and Korean automakers.

The three DC fast chargers at BMW NA HQ are CCS only. The reason being is these are not directly included in the Express Charging Corridors, but secondary locations which are more likely to support local driving, not long distance traveling.

I say “most cases” because not every single location will have a dual-standard fast charger that provides CHAdeMO, although most will. Today, CHAdeMO stations are far more widely installed in certain areas--totaling several hundred in the U.S.--than CCS stations, of which only a few dozen exist today. The "Express Charging Corridor" project will determine whether a desired location is close to an existing CHAdeMO station. If so, that location will provide only CCS cables.

I suspect this may only happen in a few locations, largely on the West Coast, since the East Coast has very few operational CHAdeMO stations to date. The East Coast corridor will connect Boston to Washington, D.C., while the West Coast corridor will extend from Portland to San Diego. Both corridors will have DC fast chargers installed at intervals of less than 50 miles, making it possible--if tedious--to do long-distance trips in electric cars with ranges of 75 to 90 miles, including the BMW i3 and the Volkswagen e-Golf.

Then, less than a week after the DC Auto Show, Kansas City Power & Light announced that it had partnered with Nissan and ChargePoint to install 1,000 electric-vehicle charging stations throughout the greater Kansas City region.


That in itself is fantastic news. But if you drill down into the press release, you will find that only 15 of the stations will be DC fast charge stations--a little disappointing. However, these 15 stations “will charge any model of electric vehicle on the market,” meaning they too will support both CHAdeMO and CCS. So BMW and Volkswagen’s project will provide CHAdeMO charging, and Nissan’s endeavor will include CCS support.

These Efacec units will be installed along the new "Express Charging Corridors" by ChargePoint and support both CHAdeMO and CCS

What just happened here?

Did the automakers all quietly agree to support both standards, so every electric-car driver can benefit? I interviewed BMW’s Electric Vehicle Infrastructure Manager, Robert Healey, on the morning of the DC Auto Show. He told me BMW has no problem with supporting dual-standard stations, because the main goal is to advance the proliferation of charging infrastructure for plug-in cars as rapidly as possible.

He went on to say that in these early stages of adoption, “a rising tide raises all boats”--and this kind of cooperation among competitors is in everyone’s best interest. While he couldn’t elaborate or speculate on the future, Healey said he would be open to similar partnerships with other automakers, should the opportunity arise.

So it's looking more and more as though the DC fast-charge standards war that everyone was predicting may be over, really before the first shot was even fired. I hope so, because if this trend continues, everybody indeed wins. Especially electric-car drivers--not only today's, but the many more to come.

BMW i3 REx Not Tax Exempt in NJ After All

My i3 REx. Will it now cost me $3,900 more than my contract calls for?

It what can only be categorized as a major misstep, BMW of North America has announced that the i3 with range extender is not tax exempt in the state of New Jersey as what was previously reported. Back on January 27th, BMW of North America manager of Electric Vehicle sales and strategy Jacob Harb told his client advisers on a conference call that the i3 REx would be treated as a zero emission vehicle in New Jersey, and qualify for the state's Zero Emission tax exemption. That was big news at the time for New Jersey residents including myself, and was one of the final deciding factors for me to actually choose the REx version over the BEV i3.

"The sales tax exemption in NJ only applies to zero-emission vehicles--and as such, does not apply to the i3 with range-extender as it does not apply currently to any vehicle with an internal combustion engine."... "Any assumption that the i3 with range-extender would qualify was premature" 
Dave Buchko, BMW's product and technology communications


The misinformation was further reinforced at the BMW i3 dealer training event held at BMW headquarters in Woodcliff Lake in April when the client advisers were again told that the i3 REx would be sales tax exempt in New Jersey. Now that BMW has begun delivering i3s with the range extender in the State since last week, the dealers haven't been collecting sales tax on the cars since they were instructed that they didn't have to. I'm one of the people that took delivery already and didn't pay sales tax. It's unclear if BMW is going to now ask me to go back to the dealer and pay the additional $3,900.00 I'd owe for sales tax. I'm not even sure they can do that. I have a signed contract that is paid in full and I wonder where the law stands on this. I don't even know if I'd want to keep it if I have to pay the sales tax now. Don't get me wrong; I love the car, and I think the REx is a great option, but this will double the cost of the range extender. Instead of it costing me $3,850, it will cost me about $7,750! It really is a great option and so far I have loved how well it works, but it's just not worth $7,750 in my opinion. I could buy a good used second car for less than that and use it for the long trips I need to take.

Then there are the people that have an i3 REx on order here in NJ and haven't taken delivery yet, what will they do? At the last minute they find out the car is now costing them nearly $4,000 more! My good friend Chris Neff's car just arrived at the dealer yesterday and he's planning on picking it up as soon as possible. I wonder how he's going to react to it now costing him nearly $4,000 more! My client adviser Manny Antunes of JMK BMW has nine i3s with the REx options on order for customers. How many will cancel their order when they find this out? I bet at least half of them. What happens to the people like me that have signed contracts, and paid for the car already? I wonder where the law stands on this? Can we now be forced to pay more than our contracts stipulate? Personally I'm not sure what I'll do if I'm told I have to pay the $3,900 now. Will BMW NA eat the extra cost for the few people that already took delivery of their REx in NJ? Will they push it on the dealers? Perhaps this was a sign that I was really meant to get the BEV i3 after all. I've already tinted the windows and now my car is being wrapped a new color at Designer Wraps down in Millville, NJ. Will JMK BMW end up with a custom-colored, Electronaut Edition i3 REx to sell as I wait another few months for a new i3 BEV to be made and delivered? This is going to be very interesting, stay tuned!

More Range Extender Details Uncovered At BMW i Dealer Training

BMW has been hosting i3 training events to get their client advisers up to speed and ready to sell the car. I'm very happy to hear they are doing this because I was really beginning to get concerned that they wouldn't properly prepare their sales staff for this unique vehicle. I even dedicated a post a few months ago to this very topic. I've now talked to a few client advisers that have done the training and they reported that they did indeed get a lot of useful information which will help them service their clients.

The i3's tiny fuel tank is seen here at right in front of the battery pack in the center of the car.  This is where the heat pump is located and why you cannot get the heat pump if you have an i3 REx

This week the latest round of training sessions are being held up at BMW headquarters in Woodcliff Lake, NJ and details of what is being taught are starting to leak out from some of the client advisers that are there. A couple things of interest shared were details about the range extender the i3 will offer as an option.

First, it was learned that the range extender is automatically activated once the state of charge drops below 6.5%. At that moment, it turns on and it's function is to bring the state of charge back up to 6.5% and to maintain that level of charge. It will not charge the car much above 6.5%, and it will not run if the car is stopped, unless the state of charge is critically low. Therefore you can't it in a stationary i3 and wait for the state of charge to increase. I knew the automatic turn on point was around 5% to 6%, but now we have an exact level when it engages.

US i3 REx customers wish they had the European "hold" feature available

You cannot manually turn the range extender off. This is contrary to what I was told by an i3 product manager at the i3 debut in New York City last July. I remember asking this specific question by saying "What if I knew I'd make it home on electric, say I only had a mile or two to go and the REx was about to turn on, could I just turn it off so it's doesn't fire up?" I was told yes, there will be a setting that will allow you to turn it off before it engages, but that setting will reset once you turn the car off. The reason for that is so that the next time you get in the car you won't forget that you had turned off the REx and you may end up needing it. I would have definitely preferred to be able to turn it off manually, and honestly can't see why that isn't going to be allowed.

The range extender exhaust is tucked away under the car so you can't see the tailpipe unless you crawl underneath to look

We also found out that the client advisers have been told that while the range extender is in operation the speed of the car will be electronically limited to 70mph. I'm not buying that; I think they were misinformed. I really think there was a miscommunication on this one because I have had conversations with people at BMW that know a lot about this and even very recently they assured me that there isn't an electronically governed speed limit while the range extender is in operation. I believe the confusion about 70mph is based on the fact that 70mph is basically the top speed that the range extender can comfortably maintain the 6.5% state of charge at while driving on relatively flat ground. The people I've talked to in Europe that have i3's with the range extender say they can drive on the highway at just about 120 km/hr (75mph) and maintain the SOC, but anything higher and the SOC will gradually diminish. It's my contention that the people running the training sessions either aren't 100% clear on this, or they really meant for the client advisers to warn the customers that 70mph is really the fastest they should drive at if they need to drive for a long distance. In any event, I believe they got this one wrong and there isn't an electronic limit, we'll find out pretty soon since the US i3 launch should be in about two weeks.

The BMW i3 range extender is located next to the electric motor and power electronics, over the rear axle.

I saved the biggest news for last. It was learned that the US version of the i3 REx will have not have a 2.4 gallon gas tank as the European version does. Instead it will have only a 1.9 gallon gas tank. I'm going to pause for a moment to let everybody scream bloody murder now...... I know it's only half a gallon, but in the case of the i3, that just reduced the gas tank by 21%! For me this is a non-issue, but I know there are a lot of people that will not like this at all. 99% of the time I use the added range of the REx it will likely be for less than 40 miles. Yes, this does reduce the utility of long range trips even more, as you will now probably have to stop for gas every 40 or 50 miles. There was no reasons given for the smaller gas tank but as far as I can imagine, this comes down to one of two things. Since BMW wants needs the i3 REx to qualify as a BEVx and one of the qualifications of the BEVx is that the car has a smaller gasoline range than it does electric range, my thinking is that one of these two things led to the smaller gas tank:

1) The EPA rating for all electric range on the REx came out lower than they believed it would. If they used the 2.4 gallon gas tank, the gas range would be slightly longer than the all electric range, therefore causing it to be disqualified for the BEVx designation. The only simple way to make the gas range less than the electric range was to reduce the gas range by using a smaller gas tank.

2) The EPA rating for the MPG while in range extender mode came out higher than expected, creating the same problem cited above; a longer range in REx mode than in all electric mode. I've heard it gets anywhere from 36mpg to 46mpg from people driving REx's in Europe so this is a possibility. If the range extender got rated at 40mpg, and was using a 2.4 gallon gas tank, then the electric range would need to be 96 miles per charge, which is highly unlikely. If they cut the tank down to 1.9 gallons, then the electric range would only need to be greater than 79 miles per charge, which I believe is attainable, even considering that the REx version will have 6.5% less battery to use than the BEV i3 does, as this is held in reserve as a buffer.
