A few weeks ago I had some time on my hands and decided to try ChargePoint so I would be prepared to use that as a backup to EA. It did not go well.
I went to the nearest one showing in my Nav system. The Nav system said the charger was "in use", but I figured I'd just wait until I could plug in. It was at a Harley dealer, and no one else was charging when I arrived. That was fortunate, as the charge cable was not long enough to reach the car unless I straddled two parking spaces to bring the left side of the car into perfect alignment with the cable outlet. I then loaded the ChargePoint app and set up an account with my credit card information.
When I tried to initiate charging nothing happened. After several tries I called the Customer Service number on the charging station. After a lengthy hold, I hung up and tried again to charge. No luck, so I sat through another hold to get a service rep on the line. When she finally came on line, she worked with me almost 15 minutes trying to initiate the charge. I finally asked her why she couldn't initiate the charge from her end, as she had my account information. She said she could and would do so. (Trying not to be rude, I didn't ask her why she didn't tell me that 15 minutes earlier.) She put me on hold. After a couple of minutes she came back to tell me that I was having problems because the charging station was out of service.
A friend who just bought a Chevy Bolt and is in queue to get his garage rigged for home charging is having to use CCS stations frequently right now. He has download five apps and opened five charging accounts (EA, ChargePoint, EVgo, Blink, and FP&L). The DCFC charging he finds to be working most consistently is at a City Mattress charging station operated by our local utility, Florida Power & Light.
