Abstract
A vehicle power supply system is provided. The vehicle power supply system includes a first power line to which a first inverter and a first battery are connected, a second power line to which a second inverter and a second battery are connected, a voltage converter, a charging and discharging control device that operates the inverters and the voltage converter, and a second regeneration permission upper limit setting unit that sets a threshold for a second SOC of the second battery. The charging and discharging control device prohibits the second battery from being charged in a case where the second SOC is larger than the threshold during regenerative deceleration, and the second regeneration permission upper limit setting unit changes the threshold to a second regeneration permission upper limit or a second normal upper limit on the basis of a state of the first battery.
