I live in the Boston area and thought I'd look up the Electrify America situation around here...
Hmm. Well, let's click on one (of the two) sites and see what's what
Hang on while I clean the non-gmo pumpkin soy latte I just sprayed all over my computer. Sorry those of you in internet land who also guffawed so hard you also soiled your made-in-canada, conflict free laptops.
They don't actually describe how this charging schedule actually works; my car for instance will tickle 100+kwh for a couple minutes and then settle into a 60-80kwh charge rate for the majority of the charging, though I rarely charge the car when it has less than 30% (I rarely go on long trips and when I do charge at low rates I plug the car in and wander away not paying attention to the charge rate).
At a dieselgate charging station, are there 3 different kinds of plugs for different charge rates, and when you are charging your "turbo porsche" at the 350kwh plug you get charged $0.89 for the whole session regardless of actual charge delivery?
I agree in some senses that having more options is better than having fewer options, but it looks to me like electrocute america is much like a diesel station when you've got a gasoline car -- there are rare occasions where you might run your gasoline car out of gas and the diesel only station is the only one in range, but that's an extremely unlikely scenario.
On the other hand, I have actually been in a situation where I would have charged at a non-supercharger fast charging station -- driving to a brewery in Vermont that had
only a chargepoint CHAdeMO and CCS and it would have been worth the $4-8 to top the car off while visiting the brewery rather than be forced to spend another 20-30 minutes topping the car off en-route back home. Weirdly they didn't have an AC charging hookup.
So if the price is right, I suppose I'd buy a trinket that let me either CHAdeMO or CCS, but I don't think I'd spend $400 for such a thing. Even more so if chargepoint gets more DC fast chargers near places I'd spend time at on the road, since I already have a chargepoint card.
