A battery system includes a battery cell, a thermoelectric cooler (TEC) that cools the battery cell, a temperature sensor that detects a temperature of the battery cell, and a battery management unit (BMU) controller. The BMU controller activates the TEC to cool the battery cell in response to determining that a state of charge (SOC) of the battery cell is greater than a threshold SOC and the temperature of the battery cell is greater than a threshold temperature.
