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.
Claims15
A vehicle battery cooling device comprising:
- first cooling means;
- and
- second cooling means, wherein a switching is made from the first cooling means to the second cooling means when a determination is made that the battery becomes equal to or higher than a predetermined temperature by battery temperature estimating means.
A vehicle battery cooling device, the vehicle switching an operation of an engine and a driving motor, a first power supply system being a high voltage power supply for an application to a vehicle drive apparatus, a second power supply system being a low-voltage power supply system for an accessory, the first power supply system having an output to be interrupted when some abnormality is detected in the battery to be switched to an engine drive, a refrigeration cycle compressor being operated in the first power supply system, second cooling means being operated in a second power supply system, and the operation of the first cooling means being switched to the operation of the second cooling means when an interruption of the first power supply system is detected.
