Abstract
The present invention reduces the possibility that parallel connection is not allowed at the time of reactivation. A plurality of battery packs () connected in parallel each include a chargeable-dischargeable battery string (), relays () provided in series to the battery string (), and a detection unit that detects the state of the battery string. A master control unit () that controls the battery packs turns off the relays of the battery packs when a circulating current falls below a cancel-allowing current and, on the basis of a result obtained by the detection unit, makes the cancel-allowing current smaller as the SOC-equivalent value of the battery pack into which the largest amount of the circulating current flows increases.
