1. A method of controlling a temperature of a battery, comprising:
- providing a thermoelectric device in thermally-conductive contact with said battery;
measuring an actual temperature of said battery;
comparing said actual temperature to a reference temperature for said battery;
heating said battery by operation of said thermoelectric device when said actual temperature is less than said reference temperature; and
cooling said battery by operation of said thermoelectric device when said actual temperature exceeds said reference temperature.

Abstract
A method of controlling a temperature of a battery is disclosed. The method includes providing a thermoelectric device in thermally-conductive contact with the battery, measuring an actual temperature of the battery, comparing the actual temperature of the battery to a reference temperature for the battery, heating the battery by operation of the thermoelectric device when the actual temperature is less than the reference temperature and cooling the battery by operation of the thermoelectric device when the actual temperature exceeds the reference temperature.

9. A method of controlling a temperature of a battery, comprising:
-
providing a thermoelectric device in thermally-conductive contact with said battery;
thermally insulating said battery from environmental heat;
measuring an actual temperature of said battery;
establishing a reference temperature for said battery;
calculating a temperature difference by subtracting said reference temperature from said actual temperature;
heating said battery by operation of said thermoelectric device when said temperature difference is a negative value; and
cooling said battery by operation of said thermoelectric device when said temperature difference is a positive value. - View Dependent Claims (10, 11, 12)
