Miraje, I don't need a Class A CDL to know that trucks operating on Li-Ion batteries makes NO engineering sense whatsoever. The weight of the battery alone is just too much, not to mention the astronomical cost thereof. Plus I'd sure like to see how such a truck would be charged. With a battery capacity approaching 500 kWh, that'll take a shit-ton of power to fully charge. Maybe hydrogen would make more sense, but even hydrogen has to be generated, and the efficiency of hydrogen generation is abysmal. You'd need 1500 kWh of energy (rough guesstimate) to produce enough hydrogen to match the energy capacity of said 500 kWh Li-Ion battery. But at least the energy-to-weight ratio is more sensible.
