A discharge controller includes secondary battery, a switch section for opening/closing a discharge path from the secondary battery to a load, a voltage detector for detecting a terminal voltage of the secondary battery, and a cut-off voltage control section for controlling the switch section to be opened when the terminal voltage as detected by the voltage detector is not more than a predetermined cut-off voltage of discharge V E , while measuring an amount of decrease per unit time of the terminal voltage as detected by the voltage detector to set the cut-off voltage of discharge V E to a lower voltage, for a larger amount of decrease per unit time of the terminal voltage as detected by the voltage detector. |
