As has been pointed out in another post, EVgo has a policy of turning off their fast chargers after a 30 minute session, regardless of the SOC of the vehicle.
Of course, customer service says this is to "protect the battery of the car" which we all know to be some major BS. Nowhere on the chargers is this pointed out, and a customer is only left to find out that their car only took 1/3 of a charge upon returning an hour later. Since (unfortunately) the Bolt starts tapering it's charge so early, you would need at least three sessions to charge a flat battery. Also, EVgo charges PER SESSION, something like $10. I appreciate that they are offering a "premium" service, and it's within their right to be complete fuckers about the pricing, but to be fuckers about the pricing AND to be fuckers about wasting hours of my time too? especially without any warning? When I plug the car in and swipe my card, I expect the machine to charge my car. If it has to charge a lot, I have to pay a lot, and that's FINE, but if I'm expecting to take an hour to fill the battery, and I walk up 50 minutes later and my car is less than half charged because it just shut off with no advanced warning? Well, I start the charge AGAIN and then go off to watch the ducks swim around for another 45 minutes, only to find AGAIN that it shut off early.This is horse shit. And you don't get the "Your charge was interrupted" text message either. On the other had, the Greenlots charger at the McDonalds in Banning kicks ass - It charges you for the power you use, at a higher rate of course, and your car gets charged. Time-based charging is not a fair business practice, and if people want to whine about vehicles camping out at fast chargers, maybe they ought to think about how flawed the current EVgo system is and how it makes stays longer at fast chargers.
Bottom line? The current EVgo policy is a giant busted piece of crap
, and until they fix it, BOLT drivers are advised to use other vendors if at all possible. Take a minute to write a nice bitchy letter to EVgo and tell them they need to change this, ESPECIALLY since the hardware is more than capable of reading state of charge and estimating charge duration.
