You need a big battery to make a naturally inefficient class of vehicle, like a pickup, work as an EV. Ford, Rivian, and Tesla all have packs larger than 100 kilowatt-hours to give their respective trucks the range, payload, and towing capacity necessary to compete in the realm of their internal combustion counterparts.
The Silverado EV can, at least theoretically, charge even faster than its 350 kW rating. If we extrapolate how quickly we know the Cadillac Lyriq with half the battery can charge—up to 190kW—we can reasonably assume that if there was a high enough current charger to support it, mattress-equipped full-size GM EVs could juice up as fast as 380 kW. The automaker won’t reveal the actual charging buffer on each cell, i.e.
