I too had a bad experience with EVgo ... I didn't have much of a choice but it turns out that that was the first charging station that I was directed to closest to where I was. Since I have found out that most of the other charging stations don't charge per minute but they charge per kilowatt hour. Also EVgo send you a card to try to join their Network and at those prices I would discourage you from doing that. Chargepoint and electrify America are the two best ones both of which have free Livewire access electrify America has 500 kilowatt hours available and charge point is free charging at Harley-Davidson if they actually have the charger.I've visited three EVGo level 3 DC fast charging stations so far. Aside from the total price gouging ($0.23/min), I've had two out of three seamless, successful charges. The third one was similar to your experience @Michelle. It shut off, saying there was an internal error. But I reconnected it and started it again and it completed no problem.
Ideally I'd be using Electrify America because of the testing that's taken place and the two free years of charging. Unfortunately I live in San Diego, where there are almost ZERO Electrify America stations. The "coming soon" grayed out map icons are almost comical. It's the largest "coming soon" charging network in there country for sure
