Abstract

A battery system is provided for a vehicle. The battery system includes, but is not limited to, comprising: a heat transfer loop, a battery cell, a thermoelectric semiconductor device coupled to the battery cell and the heat transfer loop, a variable voltage source coupled to the thermoelectric semiconductor device, and a temperature sensor coupled to the battery cell. A controller is coupled to the variable voltage source and the temperature sensor and also configured to receive a signal indicative of a temperature of the battery cell from the temperature sensor and adjust a voltage of the variable voltage source applied to the thermoelectric semiconductor device based at least in part on an evaluation of the temperature.
