What is the high-voltage electrical system?

High voltage is meant when systems in motor vehicles are operated above 25V AC / 60V DC. The system components in the vehicle electrical system must work in the specified voltage range in every driving situation.There are numerous security requirements to be observed. Factors such as contact protection, mechanics and installation guidelines play decisive roles in the operation of the HV on-board network.

All components in an electric vehicle and their interconnection make up the high-voltage on-board network. On-board network components are, for example:
  • Plug
  • Cable
  • Battery
  • PDU
  • Breakout Box
  • On-board charger
