Yes, nickel based LiON cells have the energy density but how much better than diesel must an EV truck be? My thinking is LFP chemistry may be an acceptable answer combined with truck specific charging network. My experience with our Tesla Model 3 has shown an improved density of SuperChargers easily compensates for the battery loss, 240 -> 220 mile range (new -> current.) So it makes sense: depot charging for overnight destination charging for known routes truck stop charging for more flexible routes Yes, the truck chargers will need battery buffering away from the depot. They can even be grid 'peaking' services to earn when no EV trucks are on the way. So they can make income while reducing peak grid demand. But the main advantage is allowing LFP chemistry in large trucks. Bob Wilson
