Document Type and Number:
Japanese Patent JP7413242
Kind Code:
B2
Abstract:
A power supply system includes a load circuit containing a drive motor coupled to a drive wheel; a first battery of capacity type; a second battery of output type; a power circuit connecting the load circuit, first battery and second battery; and a management ECU which controls flow of power between the first and second batteries and the drive motor, as well as flow of power from the first battery to the second battery, by operating the power circuit. The management ECU, in the case of a second SOC corresponding to the charge rate of the second battery being less than a second SOC lower limit value A, permits execution of power path control to supply the power outputted from the first battery to the second battery, and sets the second SOC lower limit value A to a greater value as the first SOC of the first battery becomes smaller.
