Abstract
A power supply systemincludes: first power lines () to which a first battery (B) is connected; second power lines () to which a second battery (B) is connected; a voltage converter () which converts voltage; a power converter which converts electric power; a management ECU () and converter ECU () which operates the voltage converter (); a smoothing capacitor connected to the first power lines (); and a motor ECU () which executes system interruption processing of determining the existence of failure of the contactors () based on a change in voltage of the smoothing capacitor. The management ECU () and converter ECU () operate the voltage converter () so that a state in which the static voltage of the first battery (B) is higher by at least the determination potential difference than the static voltage of the second battery (B).
