BATTERY AND BATTERY MANAGEMENT APPARATUS

摘要

The present invention relates to a battery managing device which comprises: a temperature sensing unit for sensing a temperature of a battery; a current sensing unit for sensing a current of the battery; an operation unit for calculating a first deterioration capacity by using the temperature of the battery at every unit time in case of vehicle driving and calculating a second deterioration capacity by using the temperature and an SOC of the battery sensed at every unit time in case of vehicle parking; and a determination unit for calculating an SOH of the battery by using the first and second deterioration capacities and determining when to exchange the battery according to the calculated SOH. The battery managing device accurately predicts lifetime of the battery by calculating an SOH of the battery in case of vehicle driving and parking in real time.
