I have found preconditioning on 120V is not as effective as on 240V. And this makes sense. The car can only draw 1.4kW on 120V due to the 12A limit on the convenience cord. Versus the full 7.2kW available to be drawn from my Level II EVSE, the 5+kW heater can be put to full use. Does anyone know if the battery is depleted by preconditioning on 120V?
