As the world shifts toward electric mobility, the charging infrastructure for electric vehicles (EVs) becomes more critical. Among the various components that make up an EV’s charging system, the Power Distribution Unit (PDU) relay stands out as a key player in ensuring the safe and efficient delivery of power to the vehicle’s battery. In this article, we will explore the role of the PDU relay in electric vehicle charging systems, its functionality, and why it is essential for the overall performance and safety of EVs.

What is a PDU Relay for EV? A Power Distribution Unit (PDU) relay for electric vehicles is an electrical component used to manage and control the flow of electrical power from the charging station to the vehicle’s battery. It works as an intermediary that ensures the proper distribution of power, preventing overloading, short-circuiting, and other potential issues that could harm the vehicle’s electrical systems. The PDU relay serves as a vital protection mechanism, controlling high-voltage circuits and maintaining safe charging conditions for EVs. Key Functions of the PDU Relay in EVs
