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.
Claims26
A thermal management system for a vehicle with an electric drivetrain, the system comprising:
- a battery system comprising at least one battery cell having a cycle life of at least 100 cycles, and an optimal operating temperature of about 75° C. or higher;
- an internal combustion engine (ICE);
- a shared thermal circuit thermally coupling the battery system and the ICE, comprising:
- a working fluid,
- at least one switch or valve for controlling the transfer of the working fluid, and
- at least one external heat exchanger;
- and
- a control system for controlling the heat exchange between the ICE and the battery system, wherein the control system actuates the at least one switch or valve.
