TonyWilliams said:Ok, it sounds like you're getting a GCFI (Ground Current Fault Interrupt). This is fairly common.
My suggestion does not involve the EVSE, since that isn't going to warm the battery much. Plus, just like a "block heater", it will work on those GCFI plugs and keep the battery at whatever temperature you have the thermostat set at. These silicone pads will just stick to the bottom of the battery and plug into 120 volts:
