AC charging supplies alternating current to an electric vehicle, whose onboard charger converts it to direct current for the battery at up to about 22 kW.
A charging curve shows how an electric vehicle's charging power changes with battery state of charge, and it decides real DC fast charging times.
DC fast charging feeds direct current from an off-board charger straight into an EV battery, adding hundreds of kilometers of range in about half an hour.
