Problems solved by technology

[0008] However, in the above-mentioned structure, in order to prevent the rotation of the cylindrical bolt, it is necessary to use a special-shaped bolt in which a part is formed into a box shape.
In addition, since the bolts are directly abutted to prevent rotation, an insulating structure is required to prevent undesired conduction or short circuit, resulting in the problem of a large number of parts and a complicated structure.

Embodiment approach 2

[0077] Figure 11 It is a perspective view showing the connection terminal 6 of the battery pack according to the second embodiment. In this figure, only a part of the prismatic battery cells 1 (the four rows on the left side) are shown in order to make the shape of the connecting terminal as a bus bar easy to see, and the rest are omitted. Furthermore, the illustration of the separator 2 is similarly omitted. exist Figure 11 Among them, three types of connection terminals are used. The second connection terminal 6B located on the right side of the figure is not used to connect the adjacent rectangular battery cells, but is used to connect the rectangular battery cells located at separated positions in the stacked state to each other. 6B is composed of a horizontal piece and a vertical piece. The horizontal piece has inclined surfaces arranged substantially in parallel at predetermined intervals. The vertical piece is bent at a substantially right angle and connects these h...

Abstract

The invention provides a battery array and battery array separator, the battery array can firmly connect a connecting terminal with the battery cell without damaging the member and prevent the common rotation of the electrodes with a simple structure in the connection of the connection terminal such as a bus bar and the like. The battery array is provided with a plurality of rectangular battery cells (1) having electrode terminals (3), separators (2) inserted between adjacent rectangular battery cells to insulate those rectangular battery cells, and connecting terminals to electrically connect adjacent electrode terminals of rectangular battery cells stacked with intervening separators. Connecting terminals are attached to electrode terminals by a threaded fastening system, and separators are provided with rotation prevention walls that contact connecting terminals and prevent connecting terminal rotation during threaded fastener tightening. Consequently, connecting terminal rotation during fastening is prevented, and deformation of a connecting terminal or battery cell is prevented.

Description

technical field [0001] The present invention relates to a battery pack and a battery pack separator formed by fixing a battery block formed by connecting a plurality of battery cells in a stacked state with a battery frame, and particularly to a battery having electrodes for connecting to connection terminals Separators for packs and batteries. Background technique [0002] A storage battery system in which a plurality of battery cells are stacked is used for charging and discharging a large current such as a power supply unit of a hybrid car or an electric car because the battery cells can be connected in series to increase the output voltage. The battery system discharges at a very high current when the vehicle accelerates, and charges at a relatively high current during conditions such as regenerative braking. This storage battery system achieves a desired output by connecting a large number of large-capacity battery cells in series and / or in parallel. [0003] The batt...
