Abstract: In a vehicle power supply system mounted on an electric vehicle, a vehicle controller switches a discharge power limit to a motor during travel of the electric vehicle according to degradation information of a battery module to which a plurality of cells are connected, the degradation information being calculated in advance before the travel of the electric vehicle. For example, the vehicle controller switches a limit of a maximum acceleration and/or maximum speed of the electric vehicle as the switching of the discharge power limit.

Abstract: A charge control map for chargers specifies the relationship between an upper limit current and charging conditions including at least one of the temperature of the chargers, the state of charge (SOC) of a secondary battery mounted in an electrically driven vehicle to be charged, the voltage of the secondary battery, and time. A charge control map for an electrically driven vehicle specifies the relationship between an upper limit current and charging conditions including at least one of the temperature of the secondary battery, the SOC of the secondary battery, the voltage of the secondary battery, and time. A charger selection unit (118) selects a charger used for charging any electrically driven vehicle of a plurality of electrically driven vehicles from among the plurality of chargers. The charger selection unit (118) selects at least one charger that least limits the charging performance of the electrically driven vehicle to be charged.
