1. A power supply system, comprising:

  • a power supply device comprising a plurality of power storage devices connected in parallel, a plurality of temperature detection units operable to detect respective temperatures of the power storage devices, and a plurality of switch elements respectively connected in series to the plurality of power storage devices;

    a load electrically connected to the power supply device;

    a power supply-side control unit operable to control the on-state and off-state of the switch elements;

    a load-side control unit operable to control the electric power that is consumed or generated by the load,wherein the power supply-side control unit performs a temperature control for the plurality of power storage devices by controlling a time ratio of the on-state and off-state of each switch element based on the temperatures detected by the plurality of temperature detection units,wherein the power supply-side control unit transmits a notification signal indicative of the execution condition of the temperature control to the load-side control unit, andwherein the load-side control unit controls the electric power that is consumed or generated by the load based on the notification signal received from the power supply-side control unit.
