To solve the dendrite precipitation problem.SOLUTION: In an AC current supply circuit for a battery, a battery 6 is connected with a power storage device 3 through a secondary coil 51 of a step-down transformer 5. A secondary AC voltage induced by the secondary coil allows AC electric power energy to reciprocate between the battery and the power storage device. The internal resistance of the battery generates resistance loss due to a secondary AC current circulating in a closed circuit composed of the secondary coil, the battery, and the power storage device. Suitably, the secondary coil connects midpoint potential points of two battery groups connected in parallel. An oscillation drive circuit applies a high-frequency voltage to a primary coil of the step-down transformer. The secondary AC voltage induced by the secondary coil allows an AC current to circulate in the closed circuit to heat the internal resistance of the two battery groups. The circulation of the AC current allows the electric power energy to reciprocate between the two battery groups.SELECTED DRAWING: Figure 1 【課題】デンドライト析出問題を改善する。【解決手段】バッテリ用交流電流供給回路において、バッテリ６は、降圧トランス５の二次コイル５１を通じて蓄電デバイス３と接続する。二次コイルに誘導された二次交流電圧は、バッテリと蓄電デバイス間に交流電力エネルギーを往復させる。バッテリの内部抵抗は、二次コイル、バッテリ及び蓄電デバイスからなる閉回路を循環する二次交流電流により抵抗損失を発生する。好適には、二次コイルは、並列接続しれた２つのバッテリグループの中間電位点を接続する。発振駆動回路は、高周波電圧を降圧トランスの一次コイルに印加する。二次コイルに誘起された二次交流電圧は、２つのバッテリグループの内部抵抗を加熱するために閉回路に交流電流を循環させる。この交流電流の循環により、２つのバッテリグループ間で電力エネルギーが往復する。【選択図】図１
