SECONDARY-BATTERY CONTROL DEVICE

摘要

An overdischarge prevention unit (40) performs an overdischarge prevention control such that electric power is charged into a battery (300) when the battery (300) has not been charged for a predetermined setting period, when the remaining capacity ratio of the battery (300) is a first setting ratio or below and when the voltage of the battery (300) is a first setting voltage or below. When the battery (300) has been charged for a predetermined setting time duration, when the remaining capacity ratio of the battery (300) exceeds a second setting ratio or when the voltage of the battery (300) exceeds a second setting voltage that is higher than the first setting voltage, the overdischarge prevention unit stops the overdischarge prevention control.
