Abstract: A battery temperature acquirer acquires a measured battery temperature of a battery module in a battery pack installed in an electric vehicle. A target temperature determination unit determines a target temperature of the battery module at the time of arrival at an installation place of a charger to which the electric vehicle is to head. A set value determination unit determines a combination of a set value for regenerative charging, a set value for output suppression, and a set value for a temperature adjustment unit such that the battery temperature becomes closer to the target temperature.

Abstract: A data acquisition unit acquires usage data of a secondary battery and battery information for specifying the type of the secondary battery. A degradation characteristic search unit searches a degradation characteristic database on the basis of the battery information and specifies a degradation characteristic information that includes a storage degradation characteristic, a charging degradation characteristic, and a discharging degradation characteristic of the secondary battery. A degradation state analysis unit estimates a storage degradation amount, a charging degradation amount, and a discharging degradation amount of the secondary battery on the basis of the usage data of the secondary battery and the specified degradation characteristic information.
