PROBLEM TO BE SOLVED: To provide a power controller capable of equalizing the power each other by the storage batteries, when the batteries are connected in series between the positive electrode line and the neutral line, and between the neutral line and the negative electrode line, and a DC power is supplied by means of three lines, i.e., the positive electrode line, neutral line and negative electrode line.SOLUTION: A power controller includes a comparison unit for acquiring the charging status of a first battery and a second battery therefrom and comparing them, and a power control unit for controlling the power transfer between the first and second batteries based on the comparison results from the comparison unit so that the charging status of the first battery and second battery is equalized. The power control unit controls the power transfer between the first and second batteries through a bidirectional step-up/down chopper circuit.SELECTED DRAWING: Figure 1 【課題】蓄電池を正極線と中性線との間、及び中性線と負極線との間に直列に接続して、正極線、中性線、負極線の３線で直流電力が供給される際に、蓄電池同士で電力を均等化することが可能な電力制御装置を提供する。【解決手段】第１バッテリ及び第２バッテリから、前記第１バッテリの充電状況と前記第２バッテリの充電状況とを取得して比較する比較部と、前記比較部の比較の結果に基づいて前記第１バッテリの充電状況と前記第２バッテリの充電状況とが均衡化するよう前記第１バッテリと前記第２バッテリとの間の電力融通を制御する電力制御部と、を備え、前記電力制御部は、双方向の昇降圧チョッパ回路を通じた前記第１バッテリと前記第２バッテリとの間の電力融通を制御する、電力制御装置が提供される。【選択図】図１
