Abstract
A power supply system includes: a first power circuit having a first battery and a first power line; a second power circuit having a second battery and a second power line; a voltage converter; a power converter; a first voltage acquisition unit which acquires a first closed circuit voltage lower limit CCVminof the first battery; a second voltage acquisition unit which acquires a second closed circuit voltage lower limit CCVminof the second battery; and a power control unit which operates the second power circuit based on a requested power, in which the power control unit isolates the second battery from the second power lines, in a case of a voltage difference between the first closed circuit voltage lower limit CCVminand the second closed circuit voltage lower limit CCVminbecoming less than a first voltage threshold value A while output limitation of the second battery is being requested.
