[0026] Such as Figure 1 to Figure 3 As shown, the battery pack device 1 according to this embodiment is a stationary type battery pack device used in general houses, factories, and the like. Specifically, the battery pack device 1 includes a casing 2, a battery module 3, an air inlet 5, an air outlet 6, an air passage (air passage) 7, an upper end fixing device 8, a lower end fixing device 9, a support 10 and a control part storage equipment 12,14.

[0027] In the battery module 3, a plurality of battery cells 15 stacked on each other such as Figure 1 to Figure 3 arrangement shown. Such as Figure 4 As shown, each battery cell 15 is formed in a substantially rectangular parallelepiped shape (thin rectangular box shape). Each battery cell 15 has a pair of terminals 15c, 15d protruding from the end face 15b of the battery cell body 15a. Each battery unit 15 is a storage battery, for example, a lithium-ion battery, a nickel-metal hydride battery, or the like.

Abstract

A battery pack device of an embodiment includes a battery module, a casing, an air inlet, an air outlet, and a ventilation channel. In the battery module, a plurality of battery cells stacked one on another are disposed. The casing is installed while housing the battery module therein. The air inlet is provided in the casing and lets an outside air into the casing. The air outlet is provided in the casing, disposed at a position higher than a position of the air inlet, and lets the air out of the casing. The ventilation channel, in the casing, connects the air inlet and the air outlet, and inclines with respect to a horizontal direction.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2010-260287 filed on Nov. 22, 2010; the entire contents of which are incorporated herein by reference. technical field [0003] In general terms, embodiments described herein relate to battery pack devices. Background technique [0004] There are known battery packs, the battery modules of which are accommodated in a case for battery storage, wherein, in the battery module, a plurality of battery cells substantially in the shape of a rectangular parallelepiped are divided between their thicknesses via an insulator or the like. direction is stacked. [0005] Batteries of this type generally require improvements in energy density (the output power per unit volume of the battery). Therefore, restrictions on component layout, such as dense arrangement of various types of components, are imposed on this type of battery p...
