An electrical energy storage device is constituted by connecting together a plurality of battery cells. Each of the battery cells includes a transformer forming unit constituted by a first inductor, a second inductor, a first core member, and a second core member, and which is capable of forming a transformer between itself and an adjacent battery cell, and a potential detection unit that detects the potential of the battery cell. A control unit compares the potentials of the adjacent battery cells based on measurement results of a potential detection unit. Furthermore, the control unit performs an equalization control to equalize the potentials of the plurality of battery cells, by supplying electrical charge from the battery cell having a higher potential to the battery cell having a lower potential.
