Abstract: A battery warming-up system includes a main battery, an electric heating portion, and a control device. The main battery is mounted to a vehicle to supply an electric power to drive the vehicle, and is warmed by a heat generation of an inner resistance of the main battery according to an input and output of the electric power. The electric heating portion heats a compartment of the vehicle by using the electric power supplied from the main battery. The control device controls a temperature of the main battery by controlling a power supply from the main battery to the electric heating portion. The output of the main battery is increased by increasing the power supply from the main battery to the electric heating portion, and the main battery can be suitably warmed. Therefore, since a power loss due to a decrease of the inner resistance of the main battery is improved or the battery output becomes sufficient, the driving power of the vehicle can be properly ensured.

Abstract: A warm-up control unit determines that a fuel-consumption improving effect cannot be obtained or it is not necessary to facilitate a warm-up operation of an engine, when a manual switch, for example, an ECO-switch, is turned on, when an accelerator opening degree is smaller than a predetermined degree and a variation of the accelerator opening degree for a unit time is smaller than a predetermined variation value, or when an ambient temperature is lower than a predetermined temperature and there is no demand for a heating operation. Then, the warm-up control unit lowers a priority for preferentially carrying out the warm-up operation of the engine, so that an adverse effect for improving fuel consumption ratio which may be caused by facilitating the warm-up operation can be avoided.
