PROBLEM TO BE SOLVED: To provide a regenerative energy storage system which enables the enhancement of regeneration to a second storage.SOLUTION: A regenerative energy storage system uses only a route running through a DC-DC converter 3 when a difference Vs between a voltage of a first power-storage part 2 and a voltage of a second power-storage part 5 is larger than a first predetermined value V1, uses only a route running through a fifth switch element S5 when the difference Vs is over a second predetermined value V2 up to the first predetermined value V1, and uses both of the route running through the DC-DC converter 3 and the route running through the fifth switch element S5 when the difference Vs is equal to or smaller than the second predetermined value V2 to change, according to a change of the difference Vs, a regenerative quantity from the route running through the DC-DC converter 3 and a regenerative quantity from the route running through the fifth switch element S5, to cause the second power-storage part 5 and thus, store a regenerative energy.SELECTED DRAWING: Figure 1

    【課題】セカンドストレージへの回生強化をする回生エネルギー蓄電システムを提供する。【解決手段】第一の蓄電部2の電圧と第二の蓄電部5の電圧との差分Vsが、第一の所定値V1より大きい場合、DC−DCコンバータ3を介するルートのみを介し、差分Vsが、第一の所定値V1以下で且つ第二の所定値V2より大きい場合、第五のスイッチ素子S5を介するルートのみを介し、差分Vsが、第二の所定値V2以下の場合、DC−DCコンバータ3を介するルートと第五のスイッチ素子S5を介するルートとを併用し、差分Vsの変動に応じてDC−DCコンバータ3を介するルートからの回生量を変動させるとともに第五のスイッチ素子S5を介するルートからの回生量を変動させて第二の蓄電部5に回生エネルギーを蓄電させる、回生エネルギー蓄電システムである。【選択図】図1
