Charging curve: power the car accepts against state of charge. The dashed line is what a 500 A cabinet can physically deliver into this 400V pack at mid-charge, which is why the curve's peak is unreachable on most CCS hardware.

Pack voltage

Modelled from 330 V at 0% state of charge to 430 V at 100%, so roughly 340–410 V across this session. On a 500 A cabinet that is 170–205 kW of headroom, against a curve that peaks at 205 kW. The cabinet runs out of amps before the pack runs out of appetite.
