Zusammenfassung:To provide an equalization device capable of suppressing cost and reducing possibility of an apparatus failure without requiring complicated control.SOLUTION: An equalization device 2 comprises single charge/discharge means Ce and control means 30. A first switch Sa connects a cathode side of the charge/discharge means Ce with any one of a plurality of contacts Sa1-Sa5 connected to cathodes of a plurality of batteries B1-B5, and a second switch Sb connects an anode side of the charge/discharge means Ce with any one of a plurality of contacts Sb1-Sb5 connected to anodes of the plurality of batteries B1-B5. The control means 30 executes control for connecting with the contacts Sa1-Sa5 and Sb1-Sb5 communicating to the cathode and the anode of one of the batteries B1-B5 selected for the first switch Sa and the second switch Sb and successively switches the batteries B1-B5 to be selected.SELECTED DRAWING: Figure 1 【課題】複雑な制御を要することなく、コスト増加を抑え、且つ、機器故障の可能性を低減することができる均等化装置を提供する。【解決手段】均等化装置2は、単一の充放電手段Ceと、制御手段30とを備え、第1スイッチSaは、充放電手段Ceの正極側と、複数のバッテリB1~B5それぞれの正極に接続される複数接点Sa1~Sa5のいずれか1つとを接続するものであり、第2スイッチSbは、充放電手段Ceの負極側と、複数のバッテリB1~B5それぞれの負極に接続される複数接点Sb1~Sb5のいずれか1つとを接続するものであり、制御手段30は、第1スイッチSa及び第2スイッチSbについて選択された1つのバッテリB1~B5の正極及び負極につながる接点Sa1~Sa5,Sb1~Sb5と接続させる制御を実行し、選択されるバッテリB1~B5を順次切り替えていく。【選択図】図1
