Abstract: The degradation suppression system includes a secondary battery, a usage history acquisition unit, a degradation amount estimation unit, a degradation factor identification unit, and a suppression control unit. The usage history acquisition unit acquires usage history information indicating the usage history of the secondary battery. The degradation amount estimation unit estimates the degradation amount of the secondary battery by using the usage history information acquired by the usage history acquisition unit. The degradation factor identification unit uses the usage history information to identify multiple degradation factors relating to the degradation amount, of the secondary battery, estimated by the degradation amount estimation unit. The suppression control unit controls the secondary battery to suppress the secondary battery degradation according to the configuration of degradation factors of the secondary battery degradation.
