1. A battery management device configured to manage a battery in an electric vehicle including the battery, a generator, and a motor, comprising:
a first switch state acquisition unit configured to acquire a state of a first switch, the first switch being turned on to start the electric vehicle;
a determination unit configured to determine to perform correction control for correcting an error in a state of charge (SOC) of the battery by controlling the SOC of the battery to a predetermined state with electric power generated by the generator when the generator of the electric vehicle is in an operable state and the first switch is operated from ON to OFF;
a correction control unit configured to perform the correction control of the SOC of the battery when the determination unit determines that the correction control is to be performed; and
a second switch state acquisition unit configured to acquire a state of a second switch for canceling execution of the correction control,
wherein, when the first switch is operated from ON to OFF while the second switch is ON, the determination unit is configured to determine that the correction control is not to be performed.
