a tesla model 3 100kwh battery charges from 10% to 80% in 30min with 250kw charger, that means 70kwh for 376km autonomy in 30 min. if u want 1200km range, u need a pack of 223kwh to get that range, and a charging speed of 2390kw to do that in 10min. a pack of 223kw would weigh 1338kg. wouldn’t that affect the car autonomy ? probably. with a hydrogen car, a 5kg of h2 would give u 400km of autonomy, refillable in 10 min, so u would need 3*5kg of h2 tanks to get that charging speed, also 3 ports. are those feasible ? will see.
