Like radio volume control.", "Image ImageDescription": "Motor controller varies pulse width to motor. Rapidly switches battery voltage on and off. Contactors (relays) may be used to reverse motor. Other contactors used for safety disconnect. Charger recharges batteries from grid. DC-DC converter charges low voltage starter battery from high voltage pack. Charger. Traction. Batteries. DC-DC.
