To avoid the voltage drop of the onboard power supply at every start, a Voltage Stabilization System (VSS) that adopts Maxwell’s ultracapacitors as the energy storage device has been designed and implemented by Continental’s Automotive Group. The VSS is a simple addition to the existing power network. The system is installed between the negative terminal of the battery and the chassis ground of the vehicle.
