If I am doing the math correctly and current (I) is equal to the power (P) divided by the voltage (V), 350kw at 240 volts would be about 1,458 amps. Correct me if I've got that wrong but that's going to require an upgrade to the service provided to the house. Maybe even a separate transformer!Right now the superchargers consume power at a rate of 150 to 350 kW depending on the version.
