These chargers are more commonly seen in motorway service stations, retail parks, and other similar locations. They convert the AC electric to DC before delivering it to the car. As a result, the vehicle’s convertor is bypassed, allowing for a faster ‘Rapid’ charge. Rapid and Ultra-Rapid chargers can supply up to 350kW DC and charge from 0 to 80 percent in as little as 30 minutes, depending on your car.
