Charging curve: power the truck accepts against state of charge. The dashed line is what a 500 A cabinet can physically deliver into this 1000V pack at mid-charge, which is why the curve's peak is unreachable on most CCS hardware.

On a Tesla SuperchargerThis is an 1000V 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 50 kW, against 1200 kW on a high-voltage cabinet. SeeSupercharger reality.

Worth knowingTesla quotes 70% in 30 minutes on a Megacharger. That needs a sustained ~1.2 MW, about twenty Model 3s charging at once, into one truck.

Pack voltage

Modelled from 750 V at 0% state of charge to 1000 V at 100%, so roughly 775–950 V across this session. On a 500 A cabinet that is 388–475 kW of headroom, against a curve that peaks at 1200 kW. The cabinet runs out of amps before the pack runs out of appetite.
