A battery control unit (50) includes an estimation device (52), a setting device (53), and a control device (51). When an open circuit voltage of the battery (22) falls within a range of a flat region, the setting device (53) sets the control storage amount to a first storage amount determined from the lower limit voltage of the flat region, the control device (51) charges the battery (22) until the open circuit voltage becomes a first voltage exceeding the upper limit voltage of the flat region after a vehicle comes into a drivable state, and the setting device (53) sets a storage amount estimated by the estimation device (52) to a control storage amount until the open circuit voltage reaches the first voltage, and sets a second storage amount determined from the open circuit voltage to the control storage amount after the open circuit voltage reaches the first voltage.
