PROBLEM TO BE SOLVED: To provide a warming-up device for a vehicular battery capable of more efficiently raising the temperature of a battery.SOLUTION: A warming-up device for a vehicular battery includes: an engine 2; a power generator 3; a plurality of power storage sections 14; a heat exchange circuit 30 including a plurality of heat exchange flow passages 16a, b, and c performing heat exchange between coolant and the power storage sections by allowing the coolant to pass through the inside and a plurality of flow rate adjustment valves 18a, b, and c provided on coolant inflow port sides of the heat exchange flow passages; a coolant supply circuit 20 for supplying coolant heated by waste heat of the engine to the plurality of heat exchange circuits; temperature detection sections 15a, b, and c for detecting the temperatures of the plurality of heat storage sections; and a warming-up control section 40 for selectively warming up the plurality of power storage sections. When the plurality of power storage sections having lower temperatures than a lower limit value in a prescribed temperature range are detected by the temperature detection sections, the warming-up control section sequentially and separately performs warming-up on the plurality of detected power storage sections.SELECTED DRAWING: Figure 1
