摘要 |
In a power supply device of the invention, when the state of charge SOC1 of a low-voltage battery is lower than a discharging reference value Shi1 below a full charge level and when the state of charge SOC2 of a high-voltage battery is not lower than a discharging reference value Slow2 at a system-off time, the low-voltage battery is charged close to its full charge level with the electric power supplied from the high-voltage battery. The lead acid battery used for the low-voltage battery has the high potential for deterioration in the continuously low state of charge SOC. The lithium secondary battery used for the high-voltage battery has the high potential for deterioration in the continuously high state of charge SOC. The charge of the low-voltage battery in combination with the discharge of the high-voltage battery enables both the low-voltage battery and the high-voltage battery to have respective favorable states of charge with little potentials for deterioration. The technique of the invention thus effectively prevents quick deterioration of both the low-voltage battery and the high-voltage battery. |
