Battery pack air cooling structure provided with thermoelectric element and control method thereof

A method of controlling a battery pack air cooling structure, the method comprising:

• measuring, by a controller, a temperature of a plurality of cell module assemblies;
• determining, by the controller, a cell module assembly, a temperature of which is to be controlled, from the plurality of cell module assemblies;
• comparing, by the controller, the temperature of the determined cell module assembly with temperatures of the remaining cell module assemblies;
• sequentially comparing, by the controller, the temperature of the determined cell module assembly with the temperatures of the remaining cell module assemblies;
• cooling, by the controller, a plurality of thermoelectric elements disposed at a cooling passageway of the determined cell module assembly when the temperature of the determined cell module assembly is greater than the temperatures of the remaining cell module assemblies;
• and
• heating, by the controller, the plurality of thermoelectric elements when the temperature of the determined cell module assembly is lower than the temperatures of other cell module assemblies.

A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

• program instructions that measure a temperature of a plurality of cell module assemblies;
• program instructions that determine a cell module assembly, a temperature of which is to be controlled, from the plurality of cell module assemblies;
• program instructions that compare the temperature of the determined cell module assembly with temperatures of the remaining cell module assemblies;
• program instructions that sequentially compare the temperature of the determined cell module assembly with the temperatures of the remaining cell module assemblies;
• program instructions that cool a plurality of thermoelectric elements disposed at a cooling passageway of the determined cell module assembly when the temperature of the determined cell module assembly is greater than the temperatures of the remaining cell module assemblies;
• and
• program instructions that heat the plurality of thermoelectric elements when the temperature of the determined cell module assembly is lower than the temperatures of other cell module assemblies.
