The purpose of the present invention is to achieve low cost balance correction in a voltage difference correction device for a power storage system that is provided with a plurality of cells. A voltage difference correction device (1) according to the present invention is provided with: a determination unit (2) that selects a first correction unit (8) and/or a second correction unit (9) on the basis of the size of the voltage difference that is output by a voltage difference detection means (4) that detects at a prescribed time interval the voltage difference between a plurality of cells (21-24) that are provided to a power storage system; and a control unit (3) that drives the first correction unit (8) or the second correction unit (9) depending on which is selected by the determination unit (2) and reduces the voltage difference. |
