A gallon of gasoline is around 33kWh of energy. 33.41kWh*20/1min = 40MW Diesel might be closer to 50MW? But regardless, it's not 33kWh per gallon of energy to the wheels. Most of the energy is wasted. So of course a battery electric truck wouldn't require that much energy to do the same work. I've seen that trucks and buses just use multiple charging cables. But yeah, you'll never charge a large truck from 0 to 100% in 1 minute. Overnight charging will be the norm.
