The present invention relates to a technique for balancing a battery pack. To this end, a battery cell balancing circuit using a single inductor comprises: a first access part for an electric energy path of a battery pack; a second access path; and an electric energy transmitting part. The battery cell balancing circuit controls a switching operation of a switch of the first access part, the second access part, and the electric energy transmitting part to selectively connect a strong cell or weak cell of the battery pack to a single inductor, thereby balancing a battery cell. Therefore, power efficiency of the battery cell is improved, and the size and cost of the battery pack are reduced.

    본 발명은 단일 인덕터를 이용하여 배터리 팩의 배터리를 밸런싱하는 기술에 관한 것이다. 이를 위해 본 발명은 배터리 팩의 전기 에너지 경로를 위한 제1 억세스부, 제2 억세스부, 전기에너지 전송부를 구비하되, 제1 억세스부, 제2 억세스부 및 전기에너지 전송부의 스위치의 스위칭 동작을 제어하여 배터리팩의 스트롱 셀이나 위크 셀을 단일 인덕터에 선택적으로 연결하는 것에 의해 배터리셀 밸런싱이 이루어지도록 한 것이다. 이에 따라, 배터리 팩의 전력 효율이 향상되고 사이즈 및 가격이 저감되는 효과가 있다.
