Embodiment Construction

[0065] Next, the storage structure of the battery pack 20 (battery pack storage structure) and the vehicle having the battery pack 20 according to the present embodiment will be described with reference to the drawings. In the following description, in principle, the same components are numbered with the same symbols, and repeated descriptions are omitted.

[0066] figure 1 It is a perspective view of the vehicle 10 including the battery pack 20 viewed from the upper rear. Here, a rear door covering the rear end of the vehicle body 11 of the vehicle 10 is omitted from illustration. The vehicle 10 is, for example, a hybrid vehicle having an electric motor and an engine as drive sources, or an electric vehicle having only a motor as a drive source.

[0067] Rear seats 12 are arranged behind the vehicle interior of the vehicle body 11 , and a storage space 14 is formed behind it, and a battery pack 20 is arranged inside the storage space 14 . The battery pack 20 is covered by a ...

Abstract

The present invention relates to a battery-pack storage structure, and the object of the invention is to provide a battery-pack storage structure capable of inhibiting overheat of the battery due to the external heat source when an accident happens. The battery-pack storage structure includes: a battery-case upper part (31) configured to store a battery stack (21); and a cooling air path (23) through which cooling air (19) for cooling the battery stack (21) flows. The battery-case upper part (31) is disposed on the battery-case lower part (15), and a bottom-part cooling air path (24), throughwhich the cooling air flows, is formed between a bottom surface (35) of the battery-case upper part (31) and a bottom surface (33) of the battery-case lower part (15).

Description

technical field [0001] The present invention relates to a storage structure for a battery pack, in particular to a storage structure for a battery pack capable of protecting a battery pack from heat sources when an accident occurs. Background technique [0002] Electric vehicles and hybrid vehicles are equipped with a large-capacity vehicle battery that supplies electric power to an electric motor to rotate the electric motor that provides driving force to the vehicle. [0003] In order to ensure a sufficient continuous driving distance, the battery for such a vehicle is heavy and takes up a large volume. Therefore, such a vehicle battery is arranged, for example, under a seat or under a rear floor. [0004] Various structures have been proposed as a structure for housing a large battery in a vehicle. Patent Document 1 describes a vehicle battery cooling device that employs a double structure as the bottom of the battery pack case. Specifically, a duct space as a double s...
