Abstract

The invention provides a battery cooling structure for a vehicle (1), comprising: a battery storage space (5) formed under a trunk (3) arranged behind a rear seat (2), and having a rear The base plate (3a) covers; the battery module (11), which is accommodated in the battery storage space (5); and the cooling device (18), which cools the battery module (11) by air sucked from the vehicle compartment (6), and release the cooled air to the storage battery storage space (5). The storage battery cooling structure of the vehicle (1) further includes: a partition member (134) for the battery storage space (5) and the rear seat (2). The rear under-seat space (133) arranged below is divided; the cabin exhaust flow path (131), which passes through the exhaust holes (134a, 134b) formed on the partition member (134) and the rear under-seat space (133 ) to return the exhaust gas released to the battery storage space (5) to the vehicle compartment (6); and the trunk exhaust flow path (132), which discharges the exhaust gas to the trunk (3).

Description

technical field [0001] The invention relates to a storage battery cooling structure for electric vehicles, hybrid vehicles and other vehicles. Background technique [0002] A battery module is mounted on a vehicle such as an electric vehicle or a hybrid vehicle that uses a motor as a drive source. For example, Patent Document 1 discloses a vehicle in which a battery module is mounted in a space below a trunk. [0003] Such a vehicle is equipped with a battery cooling mechanism for maintaining the temperature of the battery within an appropriate range in order to prevent performance degradation of the battery due to an abnormal temperature rise. For example, in the vehicle described in Patent Document 1, the battery is cooled by the air taken in from the cabin, and the cooled air is distributed and discharged to the outside of the vehicle and the space below the trunk, and released to the bottom of the trunk. Exhaust air from the space is returned to the vehicle interior th...
