How can I charge an electric vehicle? Charging an electric vehicle is as easy as charging other electric devices. Once you make sure that your car is parked and the engine is not running, just plug the charging cable of the electric vehicle to the charging unit. Open the charging port of your car and plug the other end of the cable to your car. The charging will start automatically. During the process, the cable locks itself both to the charging unit and the car. Thus, the car is charged safely. When the process is complete, you can unlock your car to remove the charging cable from the connection point.
