전기자동차용 양방향 직렬 DC-DC 컨버터의 SOC 밸런싱 알고리즘

This paper presents SOC balancing algorithm of series-connected DC-DC converter system for electric vehicle. A difference between SOC values causes a problem reducing the time of battery usage in the series-connected configuration. Therefore, the proposed balancing algorithm can improve the difference of SOC values effectively and is verified by software to prove the validity.
