In the rapidly evolving electric vehicle (EV) industry, the reliability and safety of high-voltage systems are critical. One of the key components ensuring this safety is the PDU Relay for EV (Power Distribution Unit Relay). This crucial device plays a significant role in managing the power distribution, protecting the vehicle’s electrical systems, and ensuring the overall safety of both the vehicle and its passengers.

What is a PDU Relay for EV? A PDU Relay for EV is an electrical relay that is used to control the flow of high-voltage current between different parts of the electric vehicle’s powertrain. The primary function of the PDU relay is to switch the power distribution units (PDU) on or off, which helps to distribute electricity from the battery to various critical components in the EV, such as the electric motor, on-board charger (OBC), and DC-DC converters. Relays like these are vital in electric vehicles because they not only enable the flow of current but also ensure that the power is distributed efficiently and safely, preventing any short circuits or damage to the electrical system. The high voltage circuits in EVs typically operate at 300V to 800V, making it essential for the PDU relay to handle these voltages without compromising the safety or performance of the vehicle.
