Abstract
A vehicle power supply system includes two drive motors, 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 that converts a voltage between these power lines, and a charging and discharging control device that controls charging and discharging of the batteries by operating the inverters and the voltage converter. In a case where a second SOC is equal to or greater than a second normal upper limit, the charging and discharging control device discharges power from the second battery to the second power line, and discharges a shortage of power from the first battery through the voltage converter to the second power line, wherein the shortage of power is obtained by excluding power discharged by the second battery from power required in the second power line.
