Charging curve: power the car accepts against state of charge. This car can use its full curve on a 500 A cabinet, because 800V means the same power at less current.

On a Tesla SuperchargerThis is an 800V pack and a V3 cabinet stops at 500 V, so it cannot be charged directly. The car splits its pack or runs a boost converter and accepts about 150 kW, against 350 kW on a high-voltage cabinet. SeeSupercharger reality.

Pack voltage

Modelled from 620 V at 0% state of charge to 840 V at 100%, so roughly 642–796 V across this session. On a 500 A cabinet that is 321–398 kW of headroom, against a curve that peaks at 350 kW. The pack's own taper arrives first, which is the comfortable way round.
