PCB-based solutions for power distribution in high-voltage applications
Discover our HV PDU solutions – the powerful high-voltage power distribution units from 60 VDC to 1000 VDC for mobile machines and commercial vehicles. Our HV PDUs are characterized by a compact and robust design that enables flexible configuration options and the integration of a wide range of control functions. Benefit from our decades of expertise in the development of PCB-based power distribution units using press-fit technology and comprehensive service during the project phase.
Our HV PDUs ensure stable and safe connections in the voltage range from 60 VDC to 1000 VDC for optimum power distribution between the battery, on-board charger, inverter and other electrical consumers, such as heaters or DC-DC converters.
The compact power distributors are housed in carefully sealed, corrosion-proof enclosures and enable the integration of important components for switching and protecting the functions. Even parts of the battery management can be integrated into PDUs. This increases reliability and reduces the overall size of the system.
Additional control and diagnostic functions are possible by integrating controllers into the HV PDUs. Here too, we draw on our many years of expertise in electronics development and offer customized control modules for the HV PDUs on request.
Rely on our high-voltage power distribution units for optimum performance, safety and efficiency in your electric vehicle.

We understand that every vehicle has its own unique requirements. That's why we offer you industry and application-specific solutions to ensure optimum performance in your application.
You can implement many important functions in the compact high-voltage power distribution units, such as:
The compact solutions enable the integration of important components in your customized HV PDU:
High-voltage power distribution units are usually developed individually for each vehicle and adapted to the specific requirements of our customers. Our HV PDU 600 illustrates typical functions and high-voltage components in a corrosion-protected housing. It provides power distribution in the maximum range of 600 VDC and 200 A and is based on PCB technology and press-fit technology, which enables optimum integration of HV components.
Note: HV PDU 600 was developed for demonstration purposes and is not suitable for real application.
Many well-known vehicle manufacturers already rely on our high-voltage power distribution solutions – now it's your turn!
HV power distribution units (HV PDU) are ideal for a wide range of applications in electric mobility. They enable efficient and reliable power distribution in the voltage range from 60 VDC to 1000 VDC and ensure optimum performance and safety in these demanding areas. Depending on the vehicle type, energy requirements, charging infrastructure and other key factors, several HV PDUs can also be integrated in one vehicle.
Examples of vehicle types in which our HV PDU can be installed:
In addition, our HV PDUs can be adapted to a wide variety of applications and are therefore not limited to the vehicle types mentioned above. So if you are considering an HV PDU from Würth Elektronik ICS for other fields of application, please contact us!
Power distribution units in the vehicle electrical HV system are usually developed individually for the respective vehicle architecture. The components therefore vary depending on the application and customer specification. Important components and functions for efficient Power distribution units and control include
In addition to standard components, we also implement individual and function-specific modules. Parts of the battery management can also be integrated into our HV PDU. This increases reliability and reduces the overall size of the system.
All project inquiries and the requests and requirements they contain are evaluated by our experienced sales engineers and technical project managers and appropriate solutions are offered. The development time varies depending on the requirements, project scope and customer specifications and can take several weeks.
Careful planning, concept development, design iterations, testing and validation are essential elements of our development process. We attach great importance to the quality of our products and compliance with all required performance and safety standards. Our experienced engineers are at your side throughout the entire development process and support you in the realization of your tailor-made HV PDU.
The HV PDU is a central link between the main components such as the vehicle electronics, battery, charger, inverter, electric motor and other components. Depending on the vehicle architecture, one or more HV PDUs can be integrated into the respective vehicle. The placement depends largely on the available installation space and the overall architecture, including the main components of the respective vehicle.
Thanks to our expertise in PCB technology and our own portfolio of connectors and Powerelements in press-fit technology, we are able to realize compact and highly reliable, robust solutions for the smallest installation spaces and extreme operating conditions.
The plug-and-play solution with a wide range of components enables simple system integration, installation and maintenance – regardless of where the HV PDU is placed.
The control, monitoring and diagnostic functions of our HV PDU are realized by an integrated control unit. These enable the current flow, voltage, temperature and other relevant parameters to be monitored. They also allow settings to be made, protective functions to be activated and fault conditions to be detected. The communication interfaces enable connection to the vehicle's electrical system or to external control systems. This allows the operator to monitor the HV PDU in real time and make adjustments if necessary to ensure optimum performance and safety. Our Field Application Engineers are also happy to advise and support you in programming controllers, or you can create your own program using our Try & Buy Kits.
