Abstract
A battery controller that controls a battery for supplying power to a load apparatus, includes a current detection unit that detects a discharge current and a charge current of the battery, a malfunction detection unit that detects malfunction of a voltage detector for detecting a voltage of the battery, and a contactor control unit that is provided on a power supply line through which the discharge current and the charge current flow to open/close a contactor. The contactor control unit integrates the charge and discharge current when the malfunction of the voltage detector is detected, calculates an actual charge current amount obtained by subtracting an integrated value of the discharge current from an integrated value of the charge current, and prohibits charging/discharging of the battery by controlling the contactor when the actual charge current amount is equal to or more than a predetermined value.
