An electric car runs, surprisingly, quite simply. When attached to an electricity source, the rechargeable battery within the car (usually at the front) charges and saves energy to be converted to move the car. Most modern electric cars can 'trickle-charge' on a 120V battery, but call for a 240V outlet to charge efficiently. It takes a modern electric car, on average, five hours to fully charge. Charging time depends on the manufacturer and model of the car, as well as the voltage of the power source. Once the battery is charged, and the driver pushes the pedal to move the car, the controller gathers energy from the battery. This delivers an appropriate amount through the converter, which converts the energy to mechanical energy, to the motor. This causes the wheels to turn, and the car to move.
