OK let's be honest here, a big part of this complaint we have about EVgo is actually about the Bolt and it's VERY early charge rate taper. If it could run 80KW all the way up to 80%, this point would be mostly moot, but that's not the case. The real issue here is that EVgo isn't charging for the energy consumed, like at a gas pump. There are too many variables, and right now with session based pricing, it seems that charging a Bolt at an EVgo station is a gamble as to whether you'll get your money's worth, and the odds are mostly against you.
I have to say, when people park their C-max or Prius at a DC station, it's some BS. Unfortunately, session fees and cut-offs do nothing to prevent that. I don't condone bad behavior, but a spilled root beer sends a clear message.
As for a Bolt tying up stations for over an hour, that's completely true, to get a full-ish charge anyway, BUT for the next two or three stations, the cars with the smaller packs won't have to contend with said Bolt drivers, as they'll be zooming past. At the end of the day, it's all even. Roughly speaking, everybody spends the same amount of time on a charger for the miles driven. This is cold comfort to somebody stuck last in line somewhere (never actually seen more than 1 car in line at a DC station) but it's pretty much true. As others have pointed out, the solution is to just put in more chargers, period, and not all of them need to be massive 50, 80, or one of these insane "power-cube" things with 400KW. Maybe putting up a mess of the piddly (ha) little 24KW units would be better and be an easier pill to swallow financially, but would make more sense at shopping centers where people typically spend more time than a half hour, and save the big units for when people are legitimately in a hurry. Because lets face it, it's wishful thinking that you'll be able to get seated, order, and eat that sandwich in 30 minutes.
I'm glad we're having this discussion. If there's one thing we can take away from this, it's that there are many different ways to price fast charging, and EVgo's session based system is NOT POPULAR.
