Charging Station PDU Module | Safe · Efficient · Intelligent Power Distribution
The charging station PDU module serves as the core power distribution unit within electric vehicle charging infrastructure. It reliably distributes input power to various subsystems while providing overload, short-circuit, and leakage protection, ensuring the stability and safety of the entire charging system.
What is a Charging Station PDU Module?
The PDU module (Power Distribution Unit) is one of the core components within a charging station. Its functions include:
- Distributing externally supplied electrical power efficiently to various functional units within the charging station (such as the billing module, charging gun, monitoring system, etc.);
- Providing protection and monitoring for current and voltage to prevent faults like overloads, short circuits, and leakage;
- Enabling intelligent management through communication interfaces (e.g., RS485, CAN) to interact with host computers, BMS, or EMS systems for remote monitoring and data acquisition.

Magnetic Latching Relay PDU Module Solution
The Magnetic Retention Relay PDU Module (Bistable Relay PDU) is a power distribution unit that employs a magnetic retention relay as its core switching component. Compared to traditional PDU modules, its most distinctive feature is:
- It maintains its state without requiring continuous power after being opened or closed.
- This significantly reduces energy consumption and heat generation.
- It is better suited for application in new energy vehicle charging stations and energy storage systems that demand high energy efficiency and reliability.
