High Voltage Battery Coolant Cooler Thermostatic Expansion Valve and Isolator Solenoid Valve Assembly
The high voltage battery coolant cooler Thermostatic Expansion Valve (TXV) and isolator solenoid valve assembly contains a Thermostatic Expansion Valve (TXV) with an integrated isolator solenoid valve. The isolator solenoid valve allows refrigerant flow to the Thermostatic Expansion Valve (TXV) and is controlled by the Powertrain Control Module (PCM) during A/C compressor operation requested by the Battery Energy Control module (BECM). The Thermostatic Expansion Valve (TXV) provides a restriction to the flow of refrigerant and separates the low-pressure and high-pressure sides of the refrigerant system to the high voltage battery coolant cooler, used to cool the coolant which regulates the high voltage battery system temperature.
