Power Distribution Unit (Forklift)



 high voltage power distribution unit in high voltage system solution of new energy vehicle. The high-voltage components are electrically connected through the busbar and harness to provide charge and discharge control, power on control of high-voltage components, circuit overload and short-circuit protection, high-voltage sampling, low-voltage control and other functions for the high-voltage system of new energy vehicles, so as to protect and monitor the operation of the high-voltage system.

Technical features

 PDU can also integrate BMS main control, charging module, DC module, PTC control module and other functions. Compared with traditional PDU, PDU has more vehicle function modules, more integrated functions and more complex structure. It has cooling structures such as water cooling or air cooling. PDU has flexible configuration, can be customized and developed according to customer requirements, and can meet the needs of different customers and different models. The core concept of PDU corresponds to the whole vehicle scheme and is customized according to the needs of the depot
