Abstract
A power supply apparatus includes a first battery, a second battery, and an ECU configured to determine whether the following conditions i), ii), and iii) are satisfied: i) a degree of deterioration of the second battery is lower than a first threshold; ii) a state-of-charge of the second battery is lower than a second threshold; and iii) the state-of-charge is equal to or higher than a third threshold. The second threshold is higher by a prescribed value than a lowest allowable value of the state-of-charge at which the second battery can function as a backup power supply. The third threshold corresponds to the lowest allowable value. When determining that the conditions i), ii) and iii) are all satisfied, the ECU executes single-battery-using control in which regeneration control using the regenerative electric power is executed with use of the first battery and the second battery is not used for regeneration control.
