Problems solved by technology

[0004] However, when the battery module is installed on a member extending in the vertical direction, the battery module may be separated from the rear panel due to the influence of weight.
When cooling the battery module by conducting the heat generated in the battery module to the back plate, the heat dissipation of the battery module may decrease due to separation of the battery module from the back plate.

Embodiment Construction

[0014] Hereinafter, an embodiment in which the battery pack is embodied as a battery pack mounted on a forklift will be described. In the following description, "front", "rear", "left", "right", "up" and "down" are based on a state in which the driver of the forklift is facing the front of the forklift.

[0015] like figure 1 As shown, a forklift 10 as an industrial vehicle has a body 11, a driving wheel 12 positioned at the front lower portion of the body 11, a steering wheel 13 positioned at the rear lower portion of the body 11, and a loading and unloading device positioned at the front of the body 11. The loading and unloading device includes a mast 14 erected in front of the vehicle body 11 , and a pair of left and right forks 16 attached to the mast 14 via a lift bracket 15 . Further, the forks 16 are raised and lowered together with the lift bracket 15 by the drive of a lift cylinder (lift cylinder) 17 connected to the mast 14 . In addition, the fork 16 tilts together...

Abstract

The present invention relates to a battery pack in which at least one of a battery module and an electronic component is installed on an installation object, and an industrial vehicle including the battery pack. The battery pack includes: a battery module having a plurality of secondary batteries; an electronic component that contributes to charge and discharge of the secondary batteries; and an installation body having an extending portion extending in a vertical direction. . The object to be installed has a mounting portion protruding from the extension portion in a direction intersecting the vertical direction. At least one of the battery module and the electronic component is installed on the extension portion in a state of being placed on the placement portion.

Description

technical field [0001] The present invention relates to a battery pack in which at least one of a battery module and an electronic component is installed on an installation object, and an industrial vehicle including the battery pack. Background technique [0002] As a battery pack in which battery modules are provided on members extending in the vertical direction, for example, the secondary battery device described in Patent Document 1 is mentioned. The secondary battery device described in Patent Document 1 includes a plurality of stacked battery modules. The battery stack assembly has a bottom plate, a back plate erected from the bottom plate, and a base plate fixed to the bottom plate. The battery module is mounted on the base plate. The battery module abuts against the back panel. Side panels are erected on the base plate so as to sandwich the battery modules. A packing is arranged on the battery module, and another base plate is arranged on the packing. Further, ...
