To provide a cell balance control device which equalizes charge states of three or more battery cells, capable of reducing a power loss at the equalization with the prevention of the deterioration of the battery cells.SOLUTION: A cell balance control device 1 includes change control units 511a-51na which are provided for respective three or more battery cells 111-11n to switch the connection destinations of radio power transmission units 301-30n between the battery cells 111-11n and capacitors 601-60n. When each of the battery cells 111-11n corresponding to each of the change control units 511a-51na is either a supply cell which supplies power or a supply target cell which receives the supply of the power, each of the change control units 511a-51na switches the connection destination of each of the radio power transmission units 301-30n to the battery cells 111-11n side. When each of the battery cells 111-11n is a relay cell which relays power, each of the change control units switches the connection destination of each of the radio power transmission units 301-30n to the capacitors 601-60n side.SELECTED DRAWING: Figure 1

    【課題】3個以上の電池セルの充電状態を均等化するセルバランス制御装置であって、均等化時の電力ロスを低減でき、かつ、電池セルの劣化を防止することが可能なセルバランス制御装置を提供する。【解決手段】セルバランス制御装置1は、3個以上の電池セル111〜11nそれぞれに対応して設けられ、無線電力伝送部301〜30nの接続先を、電池セル111〜11nと、蓄電器601〜60nとの間で切替える切替制御部511a〜51naを備える。各切替制御部511a〜51naは、当該切替制御部511a〜51naに対応する電池セル111〜11nが、電力を供給する供給セル、又は、電力の供給を受ける被供給セルの場合には、無線電力伝送部301〜30nの接続先を電池セル111〜11n側に切替え、電力を中継する中継セルの場合には、無線電力伝送部301〜30nの接続先を蓄電器601〜60n側に切替える。【選択図】図1
