Anyway, I think they (Ford, GM, etc) are foolish not to embrace the supercharging network and adopt a single charging interface.
They have a single charging interface - other than Nissan. (And even Nissan is switching, their next-generation EV will use the standard.)
CCS is the standard now for everything but Tesla. (Nissan's Leaf still uses the older CHAdeMO, but they're the last holdout in North America.)
And while the various charging networks out there are wildly variable in quality, having competition means prices stay low. If Tesla Superchargers were the only one out there, Tesla could set prices however they want. I will like it when two-way-data-transfer over CCS becomes standard. Right now, Tesla has the advantage that the car identifies itself to the charger, so you can put your billing information in the car, and just plug-and-go. CCS doesn't support this, so the charger unit has no way of identifying your car, so the charger unit has to handle billing itself (either with a credit card reader, RFID card linked to an account, or smartphone app.)
Personally, I think all DC quick chargers should accept credit cards, and the various chains should all work to support each other's RFID cards. It's annoying carrying three RFID cards and STILL having some that I need a separate app for.
(I own two EVs, and have a third I'll be picking up in a week.)
