AC vs DC

The EV’s onboard charger converts an alternating current into a direct current that can charge the vehicle's battery. The actual charging speed depends on the speed of the specific charger and the condition of the vehicle’s battery. AC chargers installed on the wall are a type of power supply that provide an alternating for the onboard charger.

DC chargers are external fast chargers that convert an alternating current into a direct current outside the vehicle. The charging speed depends on the output of the charger and the capacity of the battery system. Faster chargers are usually more expensive and can take up more space.
