Jedes aus Batteriepacks umfasst einen ersten und einen zweiten Stromdetektor, die einen durch einen Batteriestapel fließenden Strom erfassen. Wenn die erfassten Werte des ersten und des zweiten Stromdetektors in einem Batteriepack nicht übereinstimmen, wird der Austausch von elektrischer Energie zwischen diesem Batteriepack und einem anderen Batteriepack durch eine Steuervorrichtung durchgeführt, die einen zu jedem Batteriepack gehörenden DC/DC-Wandler in Betrieb setzt. Während des Betriebs des DC/DC-Wandlers vergleicht die Steuervorrichtung die erfassten Werte des ersten und zweiten Stromdetektors in dem einen Batteriepack mit dem erfassten Wert des ersten Stromdetektors in dem anderen Batteriepack und wählt einen normalen Stromdetektor aus dem ersten und zweiten Stromdetektor in dem einen Batteriepack aus.
