There is a big learning curve and a lot of apps to using DCFC. I would be completely screwed without plugshare, as navigation programs are lousy at finding EV charging. Come on Google, you are usually good at stuff like this. ABRP is used by others. I so far have 9 frickin' charging network apps. I hear of people using networks I have yet to encounter... Many charging stations have lousy network connections and need an RFID card that the networks seem reticent to send out. A working phone is essential for both payment at most DCFC and finding them. I don't like this. If I lose my phone, I am in big trouble.
Stations are sometimes just powered down, with no warning in their own apps.
EvGo plug and charge has worked brilliantly.
I'm in China right now, almost all payments are done here via alipay or WeChat. QR code is scanned either with or from phone, enter your password, and ping, money is sent. It works really well.
