Thermoelectric-based thermal management system
First Claim
1. A thermoelectric battery thermal management system configured to manage temperature in a temperature-sensitive region of a battery cell, the system comprising:
- a battery management controller configured to control charging and discharging of a battery cell;
a thermoelectric management controller configured to control electric power delivered to a thermoelectric device, wherein the thermoelectric device is configured to transfer thermal energy between a main surface and a waste surface upon application of electric power to the thermoelectric device, wherein the main surface of the thermoelectric device is attached to a bus bar, wherein the bus bar is in substantial thermal communication with an electrical conductor of the battery cell, wherein the electrical conductor is configured to deliver electric power to or from the battery cell, and wherein the electrical conductor serves as a conduit for conducting thermal energy between a temperature-sensitive region of the battery cell and the thermoelectric device;
a battery enclosure that encloses the battery cell; and
a printed circuit substrate comprising the battery management controller, the thermoelectric management controller, and a data connection between the battery management controller and the thermoelectric management controller, wherein the printed circuit substrate is positioned within the battery enclosure and comprises a power connection for supplying electric power to the thermoelectric device.

Abstract
Disclosed embodiments include thermoelectric-based thermal management systems and methods configured to heat and/or cool an electrical device. Thermal management systems can include at least one electrical conductor in electrical and thermal communication with a temperature-sensitive region of the electrical device and at least one thermoelectric device in thermal communication with the at least one electrical conductor. Electric power can be directed to the thermoelectric device by the same electrical conductor or an external power supply, causing the thermoelectric device to provide controlled heating and/or cooling to the electrical device via the at least one electrical conductor. The thermoelectric management system can be integrated with the management system of the electrical device on a printed circuit substrate.
