A power supply system and a power supply-side control unit and an electric vehicle are described. The power supply device comprises a plurality of power storage devices connected in parallel. When the temperature of any power storage device is higher than the predetermined temperature TH, the power supply-side control unit 211 performs the duty ratio control for the power storage devices. Also, the power supply-side control unit 211 transmits a temperature control notification signal indicative of the current temperature control condition to a load-side control unit 221, which in turn controls the electric power that is consumed or generated by the load 220 on the basis of the temperature control notification signal. The life of the power supply device as a whole is therefore prevented from shortening by inhibiting the temperature rise and temperature variation in each power storage device. It is also possible to prevent the power supply system from halting due to occurrence of an error.
