Abstract
[Task] It is an object of the present invention to provide a vehicle battery cooling device even if a situation that cannot be compensated by ordinary cooling means occurs, the efficient cooling is performed and a battery temperature can be stabilized.[Means for Solving] A cooling system of a heat exchanger 18 and a cooling system of a sub radiator 12 are provided to perform the cooling of high-power battery 6. A battery controller 31 which processes the information such as a temperature sensor 33 and so forth switches the device to perform the cooling of high-power battery 6 from the cooling system of heat exchanger 18 to the cooling system of sub radiator 12.
