Abstract
A battery unit heating apparatus installed in a vehicle which can drive by power from at least one of an internal combustion engine and an electric motor which is driven by a battery unit as a power supply, includes: an induction unit for drawing in air for heating the battery unit; and an induction control unit for controlling the induction unit, when a temperature of the battery unit is lower than a first predetermined value, so as to generate a drawing force larger than a drawing force resulting when the vehicle is set to the other mode of two modes having different drive ratios of the internal combustion engine to the electric motor while the vehicle is running in such a state that the vehicle is set to one of the two modes in which the electric motor is employed more positively than the internal combustion engine.
