Electric Water Pump




COMPONENT PARTS

Electric Water Pump






The electric water pump (1) feeds coolant by pressure, which circulates in the high voltage system cooling circuit. The high voltage system cooling circuit includes two cooling pumps. They are controlled by VCM independently so that the amount of pressure feed is adjusted according to the vehicle speed and water temperature.
The electric water pump also integrates an interface circuit that monitors the pump function for any malfunction, and it transmits a malfunction signal to VCM if necessary.
