Abstract:
A charge control device (40A, 40B, 50) is provided that controls charging and discharging of a storage battery (10) in which a plurality of storage blocks (12A to 12N), each including a plurality of cells (11), are connected in series. The charge control device includes voltage sensors (40A, 40B) that detect voltage values of the storage blocks (12A, 12B), respectively, wherein a charge and discharge process is performed in which a charge mode, in which the storage battery is charged, and a discharge mode, in which the storage battery is discharged, are alternately selected, and in which one of the charge mode and the discharge mode is switched to the other mode based on the amount of difference between the voltage values detected by the voltage sensors (40A, 40B).
