When I charge at a public charger, the kWh consumed reported by (i) the charging station is always lower than (ii) the "kWh Used" mentioned in Teslafi. The difference is about 10%.
I was expecting the 2 to be (exactly) the same.
Do you have any obvious explanation for this difference?
It could be that the public charger isn't measuring correctly the energy provided to the car. Or are the Tesla Model S readings known to incorrectly measure the kWh used?
