| description | 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.
본 발명은 배터리 관리 장치에 관한 것이다. 본 발명은 배터리의 온도를 감지하는 온도 감지부, 배터리의 전류를 감지하는 전류 감지부, 차량의 주행 시 단위 시간마다 감지된 배터리의 온도를 이용하여 제1 열화 용량을 연산하고, 차량의 주차 시 단위 시간마다 감지된 상기 배터리의 온도 및 SOC를 이용하여 제2 열화 용량을 연산하는 연산부, 및 제1 및 제2 열화 용량을 이용하여 배터리의 SOH를 산출하고, 산출된 SOH에 따라 배터리의 교체 시기를 판단하는 판단부를 포함한다. |
