Production of High-Voltage Power Distribution Units for E-Mobility

in-Tec Bensheim develops and produces individual power distribution units (PDUs) for your high-voltage range application.

Safe Distribution of High Currents.

in-Tec Bensheim is a specialist when it comes to high-voltage cabling. We develop prototypes and assume responsibility for the serial production of your customised, high-voltage power distribution unit. You can rely on our expertise.

We offer you flexible solutions with all our products and services. We assume responsibility for the complete development of the HV PDU for your application or produce in accordance with your specifications. In this regard, we can select the required components and do the material sourcing.

PDU production is possible for voltages up to 500 V DC with components that are typically available on the market. For higher voltages, we develop power distributors as special solutions.

What is a Power Distribution Unit (PDU)?

A PDU is used to distribute currents and voltages in the power grid. As such, it is a “high-voltage power distributor”. In e-mobility, the PDU receives its power from one or more batteries. Depending on the load, fuses protect the individual outputs against surges.

The currents can be distributed either actively or passively. With passive distribution, there is a parallel connection of the output lines, whereas active distribution has contactors that control the distribution to the outputs.

Contactors are electromechanical switches. The switch is opened or closed using an excitation voltage and a built-in coil. Contactors can be used to switch both DC and AC voltages with high currents.

High-voltage plug connections ensure flexibility

The PDUs can be equipped with HV plug-in systems. Thereby, when maintenance work is needed or in case of a replacement, this allows the hassle-free separation of a load or inverter from the unit. There is no need to open the PDU, which means that tightness is ensured.

Active discharge

When a load is disconnected from the PDU, the line must discharge within 60 seconds - to lower than 60 V for direct current (DC) and to lower than 48 V for alternating current (AC). Many loads or inverters support active discharging as a standard. Should this not be the case, an active discharge system can be integrated into the PDU for the respective output.

Supply in the low-voltage range

By installing voltage transformers in the Power Distribution Unit, the supply of other low-voltage power networks, such as the vehicle's on-board power supply system, is also possible.
