PROBLEM TO BE SOLVED: To provide a power storage device, which can suppress deterioration due to charging of a power storage unit.SOLUTION: A power storage device comprises: a first power storage unit; a second power storage unit having more excellent deterioration resistance of chargeable capacity to the charging than that of the first power storage unit; a voltage conversion part that converts a voltage of an electric power supplied from an output voltage of the second power storage unit or an external electric power source; and a control part that controls the voltage conversion part so as to charge at least any one of the first and second power storage units. The control part controls the voltage conversion part so as to execute an electric power contribution that the electric power is supplied from the second power storage unit to the first power storage unit before the charging of at least one of the first and second power storage units by the electric power supplied from the external electric power source.SELECTED DRAWING: Figure 6
【課題】蓄電器の充電による劣化を抑制可能な蓄電装置を提供すること。【解決手段】蓄電装置は、第1蓄電器と、第1蓄電器に比べて、充電に対する蓄電可能容量の劣化耐性が優れる第2蓄電器と、第2蓄電器の出力電圧又は外部電源から供給された電力の電圧を変換する電圧変換部と、第1蓄電器及び第2蓄電器の少なくともいずれか一方を充電するよう電圧変換部を制御する制御部とを備える。制御部は、外部電源から供給された電力による第1蓄電器及び第2蓄電器の少なくともいずれか一方の充電に先立ち、第2蓄電器から第1蓄電器へ電力を供給する電力供与を行うよう電圧変換部を制御する。【選択図】図6
