METHOD AND APPARATUS FOR CALCULATING AGING DEGREE OF BATTERY

Provided is a method of calculating an aging degree of a battery, the method including obtaining a duration of the battery in a first state, when a use state of the battery is changed from the first state to a second state, determining whether the obtained duration is greater than or equal to a first reference time, calculating an average temperature of the battery based on a first algorithm when the duration is less than the first reference time, and calculating the average temperature of the battery based on a second algorithm when the duration is greater than or equal to a reference time , and calculating the aging degree of the battery based on the calculated average temperature.
