A New Energy Vehicle Relay is an electrical switch that helps control the high-voltage circuits in an electric or hybrid vehicle. Relays are used to control the flow of electricity between the vehicle's various power systems, including the battery pack, charging system, electric motor, and auxiliary components like lights or climate control. These relays function by opening or closing electrical circuits, ensuring that the right amount of current is directed to the appropriate system at the right time.

    Importance of NEV Relays in Electric Vehicles

    In NEVs, relays play a pivotal role in managing the vehicle’s electrical systems. The complexity of electric and hybrid drivetrains requires precise control over high-power circuits. High-voltage systems, particularly those associated with EV batteries and the motor, need careful handling to avoid damage or risk. A malfunctioning relay could cause a short circuit or fail to disconnect the battery during charging, which could lead to severe safety issues.
