Abstract
This patent application is directed to thermal management systems of vehicles with an electric powertrain. More specifically, the battery system and one or more powertrain components and/or cabin climate control components of a vehicle share the same thermal circuit as the battery module through which heat can be exchanged between the battery module and one or more powertrain or climate control components as needed.
Claims18
A thermal management system for a vehicle, the system comprising:
- a control system;
- a shared thermal circuit comprising a fluid transfer module and one or more switches, the one or more switches being configured to operate based on signals received from the control system;
- a powertrain component thermally coupled to the shared thermal circuit;
- an external heat exchanger module comprising one or more heat rejection devices configured to dissipate heat in an operation mode;
- and
- a battery module having a cycle life of at least 100 cycles and being capable of operating at a temperature between about 40° C. and 150° C., the battery module being thermally coupled to the thermal circuit,
- wherein the control system is configured to cause the heat dissipated by the powertrain component to transfer to the battery module when the battery module is lower than a predetermined temperature, and
- wherein the vehicle does not comprise an internal combustion engine.
