Charging Pile PDU Module

The PDU (Power Distribution Unit) in a charging station refers to the integrated power distribution and control module within a new energy vehicle charging station. It primarily distributes the main power supply to various core components according to functional requirements while monitoring and protecting against current and voltage fluctuations. As a critical component within the charging station system, it handles power routing, high-voltage control, load isolation, and safety protection.

In DC fast-charging or AC charging stations, the PDU typically integrates modules such as high-voltage DC relays, fuses, voltage sampling, current monitoring, busbar connections, and CAN communication interfaces. This enables intelligent management of the charging process and fault protection.
