The present invention relates to a control method of battery charging for an electric vehicle for increasing battery charging performance when an abnormal deterioration cell occurs inside the battery. The control method of battery charging for an electric vehicle sequentially performs a CP or CC charging step, an abnormal deterioration cell determination and CV charging step and a battery diagnosis and charging end step, and prevents the deterioration of the battery charging performance by preventing a CV entry by the abnormal deterioration cell during the CP or CC charging. According to the present invention, the control method of battery charging for an electric vehicle is capable of charging without the deterioration of the battery charging performance by preventing a CV entry by the abnormal deterioration cell. Accordingly, the battery can be efficiently used not to decrease the performance and fuel efficiency of the vehicle.

    본 발명은 배터리 내 이상 열화셀 발생시 배터리 충전성능을 확보하기 위한 전기차용 배터리 충전 제어방법에 관한 것으로, CP 또는 CC 충전 단계, 이상 열화셀 판단 및 CV 충전 단계, 배터리 진단 및 충전 종료 단계를 순차적으로 수행하며, CP 또는 CC 충전 중 이상 열화셀에 의한 CV 진입을 방지하여 배터리의 충전성능이 저하되지 않도록 한 것을 특징으로 한다. 본 발명에 따른 전기차용 배터리 충전 제어방법은 이상 열화셀에 의한 CV 진입을 방지함으로써 배터리의 충전성능 저하없이 충전이 가능하도록 한다. 이에 따라, 차량의 성능 및 연비가 저하되지 않도록 유효하게 배터리를 사용할 수 있다.
