1)From what I have read about NEC (electric codes), a continuous load is classified as thee hours or more. Why doesn't Tesla allow you to draw 50 amps from a 50 amp outlet for three hours and then ramp down, or maybe cycle something like five minutes at 50 amps, two minutes at 40 amps? Perhaps more importantly, when using a household outlet or a 20 amp outlet, an arrangement life this could make a meaningful difference as a percentage, and at 50 amps you are around six miles more per hour of charge. 2) Can someone explain to me why the motor's inverter cannot be used as the onboard charger? It can operate as an AC to DC converter, can it not? I can get up to 60kw of regen, sure would be nice to be able to charge 60kw AC and not have chargers. ( I believe during regen the AC motor is putting DC back into the battery). Thanks.
