High Voltage Power Distribution Units (HV PDU)

High Voltage Power Distribution Units (HV PDUs) are critical components in modern electric and hybrid platforms. They ensure safe, reliable, and efficient distribution of high-voltage power across vehicle systems and industrial applications. Our portfolio of HV PDUs enables controlled power flow, protection of sub-systems, and integration of safety functions in environments where performance and uptime are essential.

What Is a High Voltage Power Distribution Unit?

A High Voltage Power Distribution Unit is an electrical assembly designed to route, protect, and monitor high-voltage circuits. It acts as the central hub for distributing power from the main battery or energy storage system to inverters, DC-DC converters, compressors, heaters, pumps, and auxiliary loads.
Typical HV PDUs operate in voltage ranges from 60 VDC to 1000 VDC, depending on system design and application requirements.

An HV PDU commonly includes:

• High-voltage fuses
• Contactors and relays
• Busbars and connection interfaces
• Pre-charge circuits
• Current or voltage measurement modules
• Safety interlock features
• Internal harnessing or PCB-based distribution

These elements ensure controlled switching, short-circuit protection, isolation, and operational safety.

Applications in Electric and Hybrid Systems

High Voltage Power Distribution Units are used across a wide range of vehicle and industrial platforms, including:

• Commercial electric vehicles
• Heavy-duty trucks and buses
• Construction, forestry, and agricultural machinery
• Material-handling equipment
• Railway and off-highway electrification
• Marine and stationary power systems

They provide a stable and predictable way to manage power distribution in demanding environments where vibration, thermal cycling, and electrical load transients are common.

Key Features of Modern HV PDUs

Selecting the right HV PDU is important for safety, system performance, and serviceability. Modern high-voltage PDUs typically offer:

• Modular or custom design adapted to platform requirements
• High short-circuit capability and integrated fuse protection
• Thermal optimization for continuous and peak load handling
• Environmental protection such as IP67 or IP6K9K ratings
• CAN-based monitoring for current, voltage, and status feedback
• Safe shutdown & isolation functionality
• Optimized packaging for tight installation spaces

Our HV PDU solutions support a wide range of architectures, from compact EV units to heavy-duty power distribution assemblies.
