Charging curve: power the aircraft accepts against state of charge. This aircraft 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 aircraft splits its pack or runs a boost converter and accepts about kW, against 350 kW on a high-voltage cabinet. SeeSupercharger reality.

Worth knowingConventional take-off, so it never pays the hover penalty, which is why its miles per kWh beat every multicopter here by a factor of three or more.

Pack voltage

Modelled from 620 V at 0% state of charge to 900 V at 100%, so roughly 704–872 V across this session. On a 500 A cabinet that is 352–436 kW of headroom, against a curve that peaks at 350 kW. The pack's own taper arrives first, which is the comfortable way round.
