Tesla: We have a single 50 amp circuit to the Teslas. Last night, the Model S was finishing up, and the Model X charge time rolled around. The resulting 80 amp spike caused the breaker to trip. All good. But, Tesla, please help! Option one: make the cars communicate to each other to avoid charging at the same time. Option two: instead of setting start times for charge, make it so the end time can be scheduled. That way, we can start a car charging, and know it will end before the other car starts. This may result in some decrement in the number of miles charged if the charge ends before the desired mileage is reached, but that is better than overloading the system even if it is circuit protected.
