How does Battery Thermal Management System Works

In liquid-cooled  battery packs, refrigerant flows through the battery's BMS (Battery Management system), transfering heat from the battery to the refrigerant through direct immersion or conduction through a battery plate or other structure. Then the refrigerant flows through the Battery Thermal Management System (BTMS) for conditioning. BTMS has two primary functions Heating and Cooling.

Heating: In cold environment, the battery pack need to be heated to facilitate charging/pre-conditioning and getting the pack temperature to ideal range. The BTMS heating loop includes a high voltage (HV) electric heater to warm the refrigerant to the desired set point.

Self-circulation Mode: The battery pack will generate heat during charging and when the vehicle is in operation/discharging. This heat needs to be managed to allow the battery pack to be at the desired set point.  If the ambient temperature is far enough below the battery pack temperature, a passive cooling loop can be used to reject heat from the coolant loop. This loop has a plate heat exchanger to reject heat from the coolant to ambient air to maximize heat transfer, improving co-efficient of performance of the BTMS, thus improving range of the vehicle.
