Abstract
A power supply system includes a first power circuit coupled to a capacity-type first battery and a drive motor, a second power circuit coupled to an output-type second battery, a voltage converter that converts a voltage between the first power circuit and the second power circuit, and a converter ECU and a management ECU that operate the voltage converter to control converter passing power in the voltage converter. The management ECU sets, when a first SOC that is a percentage of charge in the first battery is less than a predetermined lamp-on threshold and a first maximum output P_lim that is a maximum output of the first battery is more them a predetermined output threshold Pemaximum converter passing power Pcnv_max corresponding to maximum power with respect to the converter passing power toto prohibit discharging of the second battery.
