Sounds like the EVSE is at fault. It thinks the car is fully charged when it is not and you already mentioned that your car charges at public charging stations.Finally received the factory manual. When plugging charger into vehicle the blue charging light starts flashing (per manual indicates charger is "charging")
After a few seconds blue charging light goes solid blue (per manual sold blue light indicates vehicle is fully "charged"
Measured 240v at EVSE inputs. Good grounds, no leakage, dedicated circuit. I guess a visit to the dealer is next
Anyway to measure EVSE output without removing cover and voiding warranty. Any place under the hood I can measure voltage supplied to vehicle?
