Abstract

A battery cooling device includes: a rechargeable battery; an air supply unit, which cools the battery by sending external air to the battery; a battery temperature detection unit, which is used to detect the temperature of the battery; an external air temperature detection unit, which is used to detect The temperature of the external air sent by the air supply unit; and the battery control unit, if the temperature of the battery is lower than or equal to the set value, the battery control unit stops the air supply unit, wherein: the air supply unit has the function of adjusting the required air volume and during the operation of the air supply unit, if the temperature of the external air detected by the external air temperature detection unit is higher than the temperature of the battery detected by the battery temperature detection unit, the battery control unit controls the air supply unit so that the air supply unit The air volume of the air supply is less than the air volume when the temperature of the outside air is lower than or equal to the temperature of the battery.

Description

technical field [0001] The invention relates to a battery cooling device. More particularly, the present invention relates to a battery cooling device that prevents a temperature increase of a battery by controlling the operation of a cooling fan according to circumstances. Background technique [0002] An electric vehicle includes a large-capacity battery for driving. The temperature of these batteries increases during continuous use, and at a temperature higher than a predetermined temperature, the deterioration of these batteries is accelerated. Therefore, generally, in order to prevent the temperature of the battery from being higher than a predetermined temperature, a cooling system such as an air cooling system is provided and controlled, for example, during plug-in charging from a charging facility (see JP-A-2004-80914). [0003] However, in a vehicle that uses air cooling to cool the battery, if the temperature of the air that is sent is higher than the battery tem...
