Abstract
A battery pack thermal management system includes a plurality of battery cells connected to at least one DC power bus. At least one thermoelectric device is operatively disposed in thermal contact with the plurality of battery cells. At least one temperature measuring device is operatively connected to the thermal management system, and configured to measure a temperature of a predetermined portion of the plurality of battery cells. A cell balancing circuit is operatively connected to the plurality of battery cells, and configured to selectively divert a portion of electric current from at least one of the plurality of battery cells to the at least one thermoelectric device. An electronic controller is operatively connected to the cell balancing circuit, and configured to control a flow of electric current to the at least one thermoelectric device.
