No (at least not via BMW, and probably not economically from others), you can't retrofit DCFC

It does look like there are a few. I didn't realize how Plugshare different from Chargepoint. I have a question...Tesla charging stations are proprietary, right?

There's a great location (middle of the state...like smack in the middle) that has 10 spaces of "high power" chargers. But I guess maybe I can't use them because Tesla has its own connector? The only other fast chargers in my state are at Nissan dealerships.

Tesla is proprietary for Tesla only and no adapters available to their charging system. Tesla has taken the approach to sell the car and include a fast charging infrastructure for their vehicles all over North America along major corridors so that Tesla cars (Model S) can make it from supercharger to supercharger for 80% of their customer base.

Watch that Nissan is not just only CHAdeMO DC also not compatible with BMW, VW, MB, Kia and others unless of course they have a dual CHAdeMO/CCS ports on their DC chargers. Kia dealership are deploying dual CHAdeMO/CCS DC chargers on the westcoast much faster than other car dealerships and they have been welcoming to BMW's for now.

There must not be any between Boston and New York.


By April the East Coast Express charging corridor will be complete. There are currently only a few of them installed, but by April there will be a DC fast charger every 40 to 50 miles from Washington DC to Boston, so the NY to Boston drive will be no problem very soon.

I wrote a little about it in this BMW infrastructure post last month:

I live in Rhode Island. It does not seem to be the case that there are any here. The point-to-point network is great...if driving from those locations.
My experience this weekend was interesting...now that I can see PlugShare I see a lot of comments about people parking in EV spaces without EVs. When I went to a shopping plaza this weekend, both stations were blocked by regular cars not using them. DC Fast Charge is a great idea for long trips, but when I can't even find a regular station out and about for a trip to and from my HOME then it can get annoying.

how long did it take to charge with the quick charger?

I was able to charge to 80% capacity in about 15-20 minutes from 10-20%, then charging rate slows down significantly. I did not leave on DC charger longer than about 25 - 30 minutes as you can see the charging rate (speed) fall off similar to a level 2 charger after reaching the 80% mark. The DC fast chargers I used all displayed % of charge on their LCD screens plus kilowatts used during charge.

I'm not suggesting that anyone make a habit of staying connected to a DCFC while above 80%, particularly if others are waiting, but the usual point where a DCFC drops to L2 (7kW) speeds on an i3 is around 92%.

A lot of where the switch occurs, I think, depends on how hot the battery pack is and the ambient temperature.

Yes, there's potential for some variation based on those factors, but it's less of a concern with a thermally managed pack. Over many tests we've performed locally, with several different i3s and DCFC units, it has happened consistently at around 92%.

The Spark EV stays above L2 rates even beyond 92%.
