PDU is short for Power-Distribution-Unit
The power distribution unit has been designed for EV (electric vehicle) known as “electric vehicle high voltage distribution box”, “electric vehicle distribution box”, “electric vehicle distributor” and “electric vehicle safety box”. It is an important part of EV. For example, the unit supports function conversion and power distribution to each system unit. Such as engine control unit, battery management system, charging system, heating system, etc. The PDU can also provide short-circuit protection, leakage current protection and IP protection. The battery life is longer and the maintenance costs for EV are reduced with this device (easy maintenance, convenient installation, space-saving and reliable electrical connection).
The power distribution box allows different configurations of the battery packs to be connected in series or parallel.
The PDU also contains a master BMS unit (MMU) which communicates with the Pack BMS units.
