Charging curve: power the truck accepts against state of charge. This truck can use its full curve on a 500 A cabinet, because 600V means the same power at less current.

On a Tesla SuperchargerThis is an 600V pack and a V3 cabinet stops at 500 V, so it cannot be charged directly. The truck splits its pack or runs a boost converter and accepts about kW, against 270 kW on a high-voltage cabinet. SeeSupercharger reality.

Worth knowingDepot reality: overnight on a dispenser shared between trucks, not 90-minute blasts. The charger is usually the cheap part of the yard; the grid connection is not.

Pack voltage

Modelled from 520 V at 0% state of charge to 700 V at 100%, so roughly 538–664 V across this session. On a 500 A cabinet that is 269–332 kW of headroom, against a curve that peaks at 270 kW. The pack's own taper arrives first, which is the comfortable way round.
