This electronic coolant valve (electronic water valve) is a core component of the battery thermal management system for new energy vehicles. It integrates a drive motor, position sensor, and mounting bracket to precisely control the on/off state of the coolant circuit and switch the direction of water flow. It realizes the distribution of cooling/heating flow between the battery pack, motor, electronic control, and air conditioning (HVAC) circuits, and is compatible with the thermal management systems of pure electric and hybrid vehicles.
