BATTERY DEVICE AND COOLING CONTROL METHOD THEREFOR

A battery apparatus may measure a temperature of the battery apparatus, determine an estimated naturally-decreasing temperature based on information including a difference between the temperature of the battery apparatus and an atmospheric temperature in response to the temperature of the battery apparatus being higher than the atmospheric temperature, determine a stop temperature based on a reference temperature of the stop temperature and the estimated naturally-decreasing temperature, and stop a cooling operation of the battery apparatus in response to the temperature of the battery apparatus being lower than the stop temperature.
