Please check my calculations. If correct, I see a hazard in charging an EV in five minutes. Using a 30kwh battery as an example, 30x1000x60/5=360000 watts. I=W/V, I=360000/220 volts(voltage supplied to residence)=1636 amps. That would require one hellofva big conductor! The cost of increasing the voltage at the residence to get the amperage down would be very costly. The connection would be very dangerous. Even if done at a charging station, it’s going to take a lot of energy to charge the batteries in a such a short time and would cause safety concerns.
What do ya think?
