Abstract

The invention provides a device for managing battery temperature. The invention can be used for allowing the air passing through a battery to come back to a vehicle chamber, thus preventing the air conditioner efficiency from being worsened and the subpressure in the vehicle chamber; wherein, the device for managing battery temperature is provided with a passage (A7) for the air passing through the battery (12) to come back to the vehicle chamber and a valve (V4); besides, when the temperature of the battery (12) reaches to the utmost temperature, the valve (V4) is closed, thus discharging the air passing through the battery to the outside of the vehicle through a discharging port (1c).

Description

technical field [0001] The invention relates to a battery temperature management device. Background technique [0002] Conventionally, a battery for supplying electric power to a running motor etc. is mounted in a hybrid vehicle or the like, and studies have been carried out to adopt a secondary battery such as a nickel-cadmium battery, a nickel-metal hydride battery, or a lithium battery that can be repeatedly charged and discharged as the battery. Battery. However, since the charging and discharging efficiency of this type of battery decreases at high temperatures, there is known technology for cooling the battery using cold air from a rear-seat air-conditioning unit (see Patent Documents 1 and 2). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-1674 [0004] Patent Document 2: Japanese Patent Laid-Open No. 2007-185997 [0005] However, in the conventional invention, since the air passing through the battery is exhausted to the outside of the vehicle or t...
