Abstract
A thermal management system for an electrified vehicle includes a high voltage battery pack assembly, a low voltage battery, a cooling system and a low voltage heating system. The high voltage battery pack assembly comprises a battery module assembly that houses a plurality of battery cells within a high voltage battery case. The cooling system includes a cold plate that is configured to cool the high voltage battery pack assembly. The low voltage heating system comprises a heating assembly having a resistive heating element. The low voltage heating system is powered by the low voltage battery and attached to the cold plate.

A thermal management system for an electrified vehicle, the thermal management system comprising:
- a high voltage battery pack assembly comprising a battery module assembly that houses a plurality of battery cells within a high voltage battery case;
- a low voltage battery;
- a cooling system including a cold plate that is configured to cool the high voltage battery pack assembly;
- and
- a low voltage heating system comprising a heating assembly having a heating element, the low voltage heating system powered by the low voltage battery and attached to the cold plate.
A method of operating a thermal management system for an electrified vehicle, the thermal management system comprising a high voltage battery pack assembly comprising a battery module assembly that houses a plurality of battery cells within a high voltage battery case, a low voltage battery, a cooling system including a cold plate that is configured to cool the high voltage battery pack assembly, and a low voltage heating system comprising a heating assembly having a heating element, the low voltage heating system powered by the low voltage battery and attached to the cold plate, the method comprising:
- receiving, at a low voltage heating system controller, at least one input indicative of a temperature measurement;
- determining, at the low voltage heating system controller, whether the at least one input satisfies a cold temperature threshold;
- and
- activating the heating assembly based on the at least one input satisfying the cold temperature threshold.
