Each charging module will take at most 10 kW; in addition, the maximum current is the lower of 40 Amps or the current offered by the EVSE. Also, the taper will limit power draw near 100% SoC.
That means that a single charger Model S will take the following max powers if offered these currents and Voltages.
- 30A/208V J1772 — 30A x 208V = 6.24 kW
- 48A/208V J1772 — 40A x 208V = 8.32 kW
- 64A/240V J1772 — 40A x 240V = 9.60 kW
- 80A/265V HPWC — 37.7A x 265V = 10 kW
A dual charger car will accept up to 80 Amps and 20 kW, whichever comes first.
