1. A power supply system capable of supplying an electric power to a load device, comprising:
- first and second power storage devices capable of charging and discharging;
an electric power line configured to allow an electric power to be exchanged between the power supply system and said load device;
a first converter provided between said first power storage device and said electric power line to convert a voltage between said first power storage device and said electric power line;
a second converter provided between said second power storage device and said electric power line to convert a voltage between said second power storage device and said electric power line; and
a control device to control said first and second converters, whereinsaid control device controls the converter corresponding to the power storage device on a charge side so as to prevent a voltage of the charge-side power storage device from exceeding an upper limit value, and controls the converter corresponding to the power storage device on a discharge side so as to prevent a voltage of the discharge-side power storage device from falling below a lower limit value, during temperature rise control to raise temperature of at least one of said first and second power storage devices by exchanging the electric power between said first and second power storage devices through said first and second converters and said electric power line.

Abstract
During temperature rise control of a power storage device, a correction value calculation unit outputs a negative correction value when a voltage value exceeds an upper limit value. Thus, a duty command is corrected to be decreased. That is, duty command is corrected to increase a boost rate of a converter. Meanwhile, correction value calculation unit outputs a positive correction value when voltage value falls below a lower limit value. Thus, duty command is corrected to be increased. That is, duty command is corrected to lower the boost rate of the converter.
