Embodiment 1

[0054] A cylindrical battery pack module fixing toolkit in this embodiment includes a fixing part 100 and a fixing part 200 both of which are made of ABS, wherein the fixing part 200 can be installed in cooperation with the damaged part of the fixing part to refix the battery core.

[0055] Specifically, the fixing part 100 is two identical cuboid structures, the height and depth of which are one-third of the length of the battery cell, and are respectively used to fix the positive and negative poles of the battery cell. There are 12 fixing parts in 4 rows and 3 columns on the fixing part 100. The cell position 110 is a through hole, and the shape of the cell position 110 matches the end faces of the positive and negative electrodes of the battery cell. In the actual production process, the cell position 110 is set according to the shape of the battery cell to be assembled. This embodiment uses For fixing a cylindrical lithium battery, the battery core position 110 in this embo...

Embodiment 2

[0064] This embodiment is basically the same as Embodiment 1, except that the thickness of the limiting layer 120 is 1 cm protruding from the surface of the fixing member 100, and several first grooves 140 are arranged on the circumferential direction of the limiting layer 120. The component 100 is provided with cooling holes, and the component 200 is bonded and fixed with ABS glue.

[0065] Specific performance, such as Figure 5 , Figure 6 and Figure 7 As shown, it is a structural schematic diagram of different viewing angles of the location of the limiting layer 120 on the fixing member 100. The limiting layer 120 is a ring-shaped structure that protrudes 1 cm from the surface of the fixing member 100. The thickness is moderate, ensuring that the limiting layer 120 While being stably fixed at the cell position 110, it is also easy to use a cutter to destroy it; in addition, four first grooves 140 are uniformly provided in the circumferential direction of the limiting la...

Abstract

The invention discloses a cylindrical battery pack module fixing toolkit and a battery cell replacement method thereof, and belongs to the field of lithium batteries. The fixing tool comprises a fixing piece and a fixing part, wherein the fixed piece is provided with a plurality of battery cell positions which are inserted into the battery cells in a matching manner, and limiting layers which arearranged above the battery cell positions and used for limiting the movement of the battery cells and protrude outwards; the number of the battery cells is the same as that of the battery cell positions, a through hole is formed in the middle of each limiting layer, and the aperture of each through hole is smaller than the outer diameter of each battery cell; the fixing part comprises an annular limiting ring, the size of the limiting ring is consistent with the size of the limiting layer on the fixing piece, and a plurality of bosses are arranged on the surface of the limiting ring. The battery cell replacement method comprises the following steps: destroying the structure of the limiting layer, and forming a second groove to enable the boss to be inserted into the second groove in a matched manner to finish mounting the fixing part on the fixing piece. According to the invention, the replacement of one or more battery cells in the cylindrical battery pack module assembled by using the fixing piece can be realized.

Description

technical field [0001] The invention belongs to the field of lithium batteries, and more specifically relates to a cylindrical battery pack module fixing tool kit and a battery core replacement method thereof. Background technique [0002] Due to the emergence of the global energy crisis, energy-saving and environmentally friendly new energy vehicles have emerged as the times require. In order to increase the output current and / or output voltage of the battery module, the general practice is to use multiple batteries in series, parallel or in combination. The number of these batteries will reach as many as dozens. fixed together to form a battery pack module. However, with the widespread application of cylindrical lithium batteries in the field of new energy vehicles, the after-sales problems of lithium batteries have gradually emerged. Since the fixing part is generally an integrated structure, see Figure 12 and Figure 13 As shown, they are the structural schematic dia...
