Abstract: When a use range of an SOC (State Of Charge) of a secondary battery is expanded, the use range of the SOC is expanded by increasing an upper limit value or decreasing a lower limit value of the use range of the SOC. The increasing the upper limit value or decreasing the lower limit value of the use range of the SOC is determined to a side causing a smaller increase in a degradation rate of the secondary battery, based on at least one of a cycle degradation characteristic that defines a cycle degradation rate in accordance with the use range of the SOC and a current rate of the secondary battery and a storage degradation characteristic that defines a storage degradation rate in accordance with the SOC and a temperature of the secondary battery, and a typical use condition of the secondary battery based on a use history of the secondary battery.

Abstract: An input part sets either a charge time zone or a discharge time zone. A first firmware storage part stores first firmware defining all operation contents of a power supply device. An acquiring part acquires second firmware that is firmware for update, and a second firmware storage part stores the second firmware. A controller refers to the charge time zone, the discharge time zone and the like received from the input part to extract a first time zone in which neither the charge time zone nor the discharge time zone is set. The controller preferentially sets timing for updating firmware in the first time zone.

Abstract: A path finder sets a plurality of nodes in a state of charge (SOC) zone that is between a target SOC, which is set when a secondary battery provided in an electric moving body is charged, and a present SOC, and sets a plurality of nodes in a chargeable time period that is between a charging start time and a charging end time. A cost assigner refers to at least one of storage degradation characteristics, charge cycle degradation characteristics, or a time-of-use electricity fee table to assign a cost of a degradation amount or an electricity fee to each path between nodes. The path finder finds the charging path that minimizes a total cost of the paths between the nodes. A charging plan creator creates a charging plan based on the charging path found.

Abstract: A charger information holding unit of a management system holds an identification information item and charging efficiencies of a plurality of chargers for charging an electric vehicle, the identification information item and the charging efficiencies being associated with each other. A communication unit of the management system receives an identification information item on a charger from an electric vehicle connected to the charger, via a network. A creating unit of the management system creates a charging plan for the electric vehicle, based on a required charging amount and a target charging termination time. The creating unit of the management system refers to the charger information holding unit and determines a charging efficiency of the charger connected to the electric vehicle, based on the received identification information item, and creates a charging plan with the charging efficiency of the charger. The communication unit of the management system transmits the created charging plan to the electric vehicle via the network.
