Powerelements in High-Voltage Power Distribution
Powerelements in High-Voltage Power Distribution
Reliable power distribution in high-voltage applications
Powerelements in the power distribution solutions for electric and hybrid vehicles from Würth Elektronik ICS
We at Würth Elektronik ICS are inventor and manufacturer of Powerelements. We have been successfully developing and selling these on the market for decades. We also use our Powerelements in our own customized power distribution solutions for mobile machines and commercial vehicles. The company's comprehensive expertise, which covers the entire value chain from development and production to the application of Powerelements, enables the optimum implementation of individual customer requirements.
Due to their robustness and ability to transport high currents, Powerlements are also ideally suited for use in high-voltage power distribution units (HV PDUs).
Powerelements can be used in the HV Power Distribution Units for a wide variety of purposes, for example for:
- Connection of HV fuses
- Connection of HV relays
- Connection sensors
- Connection of HV connectors
Find out more about the many possible applications of our Powerelements by clicking on the action areas in the application example of our HV PDU demonstrator.

Advantages of using Powerelements in HV solutions
As part of the system, Powerelements help to reduce the number of cables in the system. As a result, compact and reliable power distribution units can be realized.
They ensure robust and durable electrical and mechanical connections that can withstand extreme environmental conditions, such as vibrations. Common connection types are:
- Wire-to-board connections
- Board-to-board connections
- Component-to-board connections
- Busbar-to-Components connections
Furthermore, they can be flexibly adapted to different requirements and space conditions.
