Charging curve: power the car accepts against state of charge. This car can use its full curve on a 500 A cabinet, because 400V means the same power at less current.

Worth knowingAir-cooled pack: a second fast charge in a row (“rapidgate”) drops it to ~25 kW.

Pack voltage

Modelled from 300 V at 0% state of charge to 400 V at 100%, so roughly 310–380 V across this session. On a 500 A cabinet that is 155–190 kW of headroom, against a curve that peaks at 50 kW. The pack's own taper arrives first, which is the comfortable way round.
