My Tesla is an early model, so charging at their stations is free. Paying a monthly usage bill would fine too. The bad thing is having to use a flaky UI every time I need to charge remotely (which is only every month or two). I think ChargePoint's fundamental problem is in order for their app to enable charging:

- the app must be installed and updated

- it must get an accurate location from GPS to look up the ID number of closest station (and often they're adjacent, so the next one is 12' away).

- my cellular data, and the base station's cellular data have to work

- all inside a concrete parking garage.

so it only works 3/4 of the time.
