Abstract
A battery control unit includes an estimation device, a setting device, and a control device. When an open circuit voltage of the battery falls within a range of a flat region, the setting device sets the control storage amount to a first storage amount determined from the lower limit voltage of the flat region, the control device charges the battery 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 sets a storage amount estimated by the estimation device 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.
