I had Caliban on a 7 kW type 2 charger yesterday and he charged at 6.5 kW solidly for over six hours from 20%, with the rate falling off a bit just as he approached 100%. Then he balanced for half an hour and done. Nothing untoward at all. I couldn't see the power draw during balancing due to the change in app, except for a short period when the car was drawing 1.4 kW, but I could still see when it ended.
So kind of Blink Charging to install destination chargers 50 yards from my friends' house. And then somehow to lose the record that I was charging and fail to stop the charge after four hours, and fail to bill me (should be 69p which is highway robbery for an AC charger).
