Abstract
A charge and discharge control device includes a storage charge level determining unit that selects one range from a first charge level range lower than a second charge level range and a third charge level range higher than the second charge level range, and determines a charge level at storage during which charge and discharge of a battery are not performed. The second charge level range can be a range of charge level including a maximum value of storage degradation, and the storage degradation can be degradation of the battery over time. The charge and discharge control device can further comprise a charge and discharge control unit that controls charge and discharge of the battery on the basis of the charge level at storage.
