A New Energy Vehicle Relay is an electrical switch used to control high-voltage circuits in electric vehicles, particularly in systems like battery management, motor controllers, and on-board chargers. These relays are designed to handle the unique demands of EVs, which often operate on higher voltages and require precise control of electrical flows. Unlike conventional relays found in internal combustion engine (ICE) vehicles, NEV relays must be capable of managing large currents, providing safety features, and supporting advanced control systems for optimized vehicle performance.
