Therefore, the battery module needs to be regularly or irregularly balanced. During the battery module balanced maintenance, electrode extraction is a very important process. Balancing maintenance requires connecting the positive and negative poles of the battery cell. Usually, the battery cells of the battery module do not have poles and the pole pieces are small, which cannot effectively connect the positive and negative poles of the cell. Currently, in order to connect the pole pieces, the pole piece pins need to be tilted up and then clamped with a wire harness clamp. This method will cause deformation of the battery pole piece and may cause damage to the battery electrode.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] The present invention is described in further detail below with reference to the accompanying drawings:

[0032] A battery electrode lead-out tool 2, such as Figure 1-6 As shown, it includes a crossbeam 21, and a clamping assembly 22 and a sliding assembly 3 installed on the crossbeam, the clamping assembly 22 includes a fixed end plate 221 and a movable end plate 223 that cooperate with the battery module 1; the lead-out mechanism 32 is slidably installed on the crossbeam 21, the lead-out mechanism 32 includes a sliding block 31 and a lead-out mechanism 32 installed on the sliding block 31, the lead-out mechanism 32 includes a probe 326 installed on the sliding block 31, and the inner end of the probe 326 cooperates with the electrode 12 of the battery 11 of the battery module 1.

[0033] The lead-out tooling is fixed to the battery module 1 through the clamping assembly 22. The inner end of the probe of the lead-out mechanism contacts the electrode 12 of the battery, and the outer end is connected to the external device as the connection end to realize the lead-out and exposure of the battery electrode. The electrode lead-out can be performed on battery modules of different specifications, and the versatility is high.

[0034] like Figure 4 、 Figure 5 and Figure 6The probe 326 includes an inner probe 321 and an outer probe 323. The lead-out mechanism 32 also includes a collar 322 and a spring 325. The collar 322 is mounted on the sliding block 31, and the inner probe 321 is slidably mounted on the collar 322. One end of the spring 325 is connected to the contact at the lower end of the inner probe 321, and the other end is connected to the collar 322. The outer probe 323 is mounted on the outer end of the inner probe 321. The pressure of the spring 325 ensures effective contact between the probe and the electrode.

[0035] More specifically, the diameter of the outer probe 323 is larger than the inner diameter of the ring sleeve 322; the outer diameter of the contact is larger than the inner diameter of the ring sleeve 322. The displacement of the probe is limited. The probe can be made of copper.

[0036] like Figure 2 and Figure 3 The lead-out fixture 2 includes two spaced-apart beams 21. A slide rail 211 is positioned on one side of the beam 21. The rail serves as a guide for a sliding block 31, guiding its movement. A bolt 312 is positioned on one side of the sliding block 31, the inner end of which engages with the slide rail 211. The position of the sliding block 31 can be easily adjusted to ensure contact between the probe and the electrode. The two beams 21 ensure smooth movement of the sliding block. The overall shape of the sliding block is similar to an M.

[0037] like Figure 3 A gap 212 is provided between the two crossbeams 21; a boss 313 is provided on the sliding block 31, and the lead-out mechanism is mounted on the boss 313. Slide grooves 311 are provided on both sides of the boss 313 to cooperate with the crossbeams 21. The cross-sectional area of ​​the two crossbeams is not limited to a rectangle and can also be other shapes.

[0038] like Figure 1 and Figure 3 , the fixed end plate 221 cooperates with a side wall of the battery module 1. Figure 2 The movable end plate 223 is provided with a second hand-tightening bolt 225 that engages with the other side wall of the battery module 1. The second hand-tightening bolt 225 secures the movable end plate 223 to the battery module. The movable end plate 223 is slidably mounted on the crossbeam 21. The movable end plate 223 is provided with a first hand-tightening bolt 224 that engages with the crossbeam. The first hand-tightening bolt 224 secures the sliding block 31 to the crossbeam. A gasket 226 is provided on the inner side of the movable end plate 223 to provide a buffering effect.

[0039] The crossbeam 21 and the sliding block 31 are made of bakelite, which is non-conductive, lightweight, insulated, and portable. They are highly versatile, cost-effective, and easy to manage. This new design allows for electrode extraction without damaging the original electrode sheets on the battery module, and facilitates easy clipping and quick assembly and disassembly.

[0040] The steps are as follows:

[0041] Step 101: Check whether the battery modules are placed horizontally and neatly.

[0042] Step 102: Check whether the lead-out fixture is complete and whether the movable end plate and the slider block move normally.

[0043] Step 103: Clamp the fixed end plate of the lead-out fixture on one side of the module, and fix the movable end plate on the other side.

[0044] Step 104: Move the slider so that the probe inside the slider is aligned with the electrode.

[0045] Step 105: While tightening the probe, rotate the first hand-tightening bolt and the second hand-tightening bolt of the movable end plate to clamp the battery module.

[0046] Step 106: Plug the banana plugs of the external equalization harness into the external probes. The external device begins testing.

[0047] The multiple components of the present invention have been optimized and designed many times, and the current structure is relatively convenient and easy to operate.

[0048] This new lead fixture can stably clamp battery modules of varying sizes. The lead fixture and slider block can be quickly assembled and disassembled, and the slider block can be quickly moved to provide a stable connection between electrodes. The measurement range of the electrode lead fixture and the number of sliders can be calculated based on the battery module's external dimensions, allowing the shapes of the fixed and movable end plates to be designed.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
