Abstract
In a hybrid control device performing cooling control of a secondary battery of a hybrid vehicle, the hybrid control device limiting the amount of charge/discharge of the secondary battery based on an air volume flow of a cooling fan cooling the secondary battery, an operation control mode of the secondary battery cooling fan is changed from an ordinary control mode to a power mode in which an air volume flow of the cooling fan is larger than in the ordinary control mode, whereby a limiting value of the amount of charge/discharge of the secondary battery is varied to expand the usable range of the secondary battery. Accordingly, when improvement of drive power performance is desired by an operator more than low noise within the vehicle, the amount of charge/discharge of the secondary battery is not limited by the cooling fan, and larger drive power performance is thus achieved.
