Battery Charging

Onboard Charger

I’m planning on having an on-board battery charger to allow me to take advantage of charging stations.

J1772 Combo Socket

J1772 chargers are usually called “level 1” or “level 2” chargers. These are far more common but charge cars far more slowly than CHAdeMO chargers. Level 1 chargers provide up to 16 amps at 120 volts (1.9 kW). Level 2 chargers provide up to 80 amps at 240 volts (19.2 kW). Chargers from ChargePoint are typically 6.6 kW Level 2 J1772 chargers. For comparison, a standard household outlet can provide 12 amps at 110 volts (1.4 kW).

Tesla Supercharger Socket

Tesla has it’s own proprietary charging socket design.

The Tesla Superchargers are capable of an output of 250 amps at 400 volts (100 kw). Tesla sells a CHAdeMO-to-Telsa adaptor, but no one makes an adapter the other way around.
