To provide a technique for charging a high-capacity vehicular power supply system efficiently in a short time.SOLUTION: Positive-side switches S1-S4 are connected between a positive power line of a power storage unit 11 and positive electrode terminals of multiple power storage modules M1-M4. Negative-side switches S8-S11 are connected between a negative power line of the power storage unit 11 and negative electrode terminals of the multiple power storage modules M1-M4. Serial connection switches S5-S7 are connected between a positive electrode terminal of one of two adjacent power storage modules among the multiple power storage modules M1-M4 and a negative electrode terminal of the other power storage module. A management unit 12 connects the multiple power storage modules M1-M4 in parallel when driving a vehicle 1 with power discharged from the power storage unit 11, and connects the multiple power storage modules M1-M4 in series/in series-parallel when charging the power storage unit 11 from a battery charger 4.SELECTED DRAWING: Figure 1
【課題】高容量の車両用電源システムを、短時間で効率的に充電する技術を提供する。【解決手段】正側スイッチS1−S4は、蓄電部11の正の電力線と、複数の蓄電モジュールM1−M4の正極端子との間にそれぞれ接続される。負側スイッチS8−S11は、蓄電部11の負の電力線と、複数の蓄電モジュールM1−M4の負極端子との間にそれぞれ接続される。直列接続用スイッチS5−S7は、複数の蓄電モジュールM1−M4の隣接する2つの蓄電モジュールの一方の正極端子と他方の負極端子間にそれぞれ接続される。管理部12は、蓄電部11から放電される電力により車両1を駆動する場合、複数の蓄電モジュールM1−M4を並列接続させ、充電器4から蓄電部11を充電する場合、複数の蓄電モジュールM1−M4を直列/直並列接続させる。【選択図】図1
