Problems solved by technology

[0005] However, if the number of single cells included in the single cell group is too large, mounting errors of the electrode terminals and the like accumulate, and the distance between the electrode terminals of the opposite electrodes may become wider or narrower beyond the allowable range.
In this case, if the above-mentioned battery wiring module is used, it may be difficult to install the bus bar between the electrode terminals.

Embodiment approach 1

[0041] (battery module)

[0042] Below, refer to Figure 1 to Figure 18 Embodiment 1 of the present invention will be described. figure 1 It is a plan view of the battery module 1 including the bus bar 2 with a cover according to the first embodiment. figure 1 The illustrated battery module 1 is used as a driving source for vehicles such as electric vehicles and hybrid vehicles. like figure 1 As shown, the battery module 1 is formed by a first battery module 1A and a second battery module 1B connected to each other via a bus bar 2 with a cover. figure 1 The first battery module 1A is shown on the left, and the second battery module 1B is shown on the right. also, figure 1 The lower side in corresponds to the front side (front side) of the battery module 1, figure 1 The upper side in corresponds to the rear side (rear side) of the battery module 1 . in addition, figure 1 The left-right direction in corresponds to the left-right direction of the battery module 1 .

Embodiment approach 2

[0131] Next, refer to Figure 19 Embodiment 2 will be described. Figure 19 It is a plan view of the bus bar 2A with a cover of Embodiment 2. Covered bus bar 2A of the second embodiment is formed by attaching a bus bar cover 5A to the same bus bar 21 as in the first embodiment. The basic structure of this bus bar cover 5A is the same as that of the bus bar cover 5 of the first embodiment. However, the bus bar cover 5A of the present embodiment has a structure in which the engaging portion 531 and the engaged portion 54 included in the bus bar cover 5 of the first embodiment are removed.

[0132] In the bus bar cover 5A of the present embodiment, the respective cover portions 53A, 53B are attached to the housings 512A, 512B with adhesive tape or the like, respectively. In this way, each cover part 53A, 53B can also be attached to each frame body 512A, 512B with an adhesive tape etc., respectively.

Abstract

This insulating bus bar cover (5) is attached to a bus bar (21), and both ends (23A, 23B) of the bus bar cover (5) are secured to positive and negative electrode terminals (32A, 32B) in order to provide an electrical connection between the counter electrode terminals (32A, 32B), between a group of electric cells (3B) comprising a plurality of electric cells (31), which contains the positive and negative electrodes (32A, 32B), arranged in a line, and a group of the same type of electric cells (3C), which are adjacent to the aforementioned group of electric cells (3B). The bus bar cover (5) is provided with: a body part (51) that covers the bus bar (21) in such a manner that both ends (23A, 23B) of the bus bar (21) are exposed; hinges (52A, 52B) disposed at the ends of the body part (51);and lids (53A, 53B) that are attached to the body part (51) via the hinges (52A, 52B), and are swung by the hinges (52A, 52B) in such a manner as to cover the ends (23A, 23B) and to expose the ends (23A, 23B).

Description

technical field [0001] The invention relates to a bus bar cover and a bus bar with a cover. Background technique [0002] A battery module for a vehicle in an electric vehicle, a hybrid vehicle, or the like includes a battery pack in which a plurality of battery cells are arranged in a row. Each unit cell constituting the unit cell group has an electrode terminal on the positive electrode side and an electrode terminal on the negative electrode side, respectively, and the electrode terminals on opposite electrodes of adjacent single cells are electrically connected by a metal bus bar. [0003] The bus bars are respectively mounted between the electrode terminals at multiple positions on the cell group. With such a bus bar, the cells constituting the cell group are electrically connected in series with each other. [0004] In addition, if the bus bars are installed one by one between the electrode terminals of the battery cells, the installation work takes time. Therefore,...
