Description

Technical Field

[0001] This utility model belongs to the field of battery pack testing technology, specifically relating to an auxiliary tooling for battery pack aging testing. Background Technology

[0002] Battery pack aging testing refers to a testing process that simulates the operating conditions of batteries under long-term use or extreme environments to evaluate their performance degradation, lifespan changes, and safety. Typically, during aging testing, the battery pack's electrical energy is collected. By collecting this data, the battery's performance changes, aging characteristics, and reliability can be assessed.

[0003] Currently, common battery packs have multiple data acquisition terminals. When collecting energy data from the battery pack, alligator clips and acquisition cables are typically used. The alligator clips are tightened onto the battery pack's acquisition terminals, and the acquisition cables connect the alligator clips to external testing equipment, such as ammeters, voltmeters, and temperature detectors. While this structure allows for energy data acquisition using alligator clips and acquisition cables, the lack of constraint during cable installation leads to tangling and knotting between the multiple acquisition cables during installation. This affects the installation and removal of the alligator clips and acquisition cables, ultimately impacting testing efficiency. Utility Model Content

The insulating plate has multiple through holes arranged in a matrix. The insulating plate is used to install onto the upper surface of the battery pack. The upper surface of the battery pack has multiple acquisition terminals that extend into the through holes, and the multiple acquisition terminals correspond one-to-one with the multiple through holes. There are multiple acquisition wires and multiple acquisition clamps. The insulating plate also has multiple wire grooves or multiple wire tubes. The multiple acquisition wires are fixed in the multiple wire grooves or wire tubes respectively. One end of the acquisition wire is connected to the acquisition clamp, and the other end is used to connect to external testing equipment. The number of acquisition wires and acquisition clamps is equal to the number of through holes. The acquisition clamps are set in the through holes and clamped to the acquisition terminals. The multiple acquisition clamps correspond one-to-one with the multiple through holes, and each acquisition clamp is connected to one acquisition wire.

[0006] In one embodiment of this utility model, the through holes are arranged in N rows and M columns, and the wire grooves or wire tubes are distributed along the length of the insulating plate. Each row of through holes has a wire groove or a wire tube on its lower side.

[0007] In one embodiment of this utility model, the through holes are arranged in 5 rows and 9 columns, and the number of wire grooves or wire tubes is 5.

[0008] In one embodiment of this utility model, when the insulating plate is provided with a conduit, the acquisition line is inserted into the conduit. The auxiliary tooling also includes a support member, which includes a base rod and a ring. The base rod is fixedly connected to the insulating plate, and the ring is fixedly connected to the base rod. The conduit is sleeved in the ring.

[0009] In one embodiment of this utility model, multiple support members are provided, and the multiple support members are distributed sequentially along the length direction of the conduit.

[0010] In one embodiment of this utility model, the spacing between any two adjacent support members is equal along the length direction of the conduit.

[0011] In one embodiment of this utility model, the side wall of the conduit is provided with multiple perforations, and one end of the acquisition line extends through the perforations and is connected to the acquisition clip.

[0012] In one embodiment of this utility model, when the insulating plate is provided with a wire groove, the acquisition line is embedded in the wire groove. The auxiliary tooling also includes a U-shaped limiting member. The U-shaped limiting member includes a left rod, an upper rod and a right rod connected in sequence. The left rod and the right rod are respectively arranged on both sides of the wire groove. The left rod and the right rod are both fixedly connected to the insulating plate. The acquisition line is located between the U-shaped limiting member and the wire groove.

[0013] In one embodiment of this utility model, the insulating board is further provided with multiple labels, which are respectively disposed on the sides of multiple through holes.

[0014] In one embodiment of this utility model, the insulating board is an epoxy resin board.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the above-mentioned solution of this application, the auxiliary tooling includes an insulating plate, acquisition wires, and acquisition clamps. The insulating plate has multiple through holes arranged in a matrix. The insulating plate is used to install onto the upper surface of the battery pack. The upper surface of the battery pack has multiple acquisition terminals that extend into the through holes. Each acquisition terminal corresponds to one through hole. There are multiple acquisition wires and multiple acquisition clamps. The insulating plate also has multiple wire grooves or wire conduits. Multiple acquisition wires are fixed in the multiple wire grooves or wire conduits. One end of the acquisition wire is connected to the acquisition clamp, and the other end is used to connect to external testing equipment. The number of acquisition wires and acquisition clamps is equal to the number of through holes. The acquisition clamps are set in the through holes and clamped to the acquisition terminals. Each acquisition clamp corresponds to one through hole, and each acquisition clamp is connected to one acquisition wire. With this structure, during aging tests of the battery pack, an insulating plate can be placed on the upper surface of the battery pack, with multiple data acquisition terminals on the upper surface of the battery pack positioned within multiple through holes. The data acquisition clips are then clamped onto the data acquisition terminals, allowing the battery pack's electrical energy to be conducted to external testing equipment via the clips and acquisition lines, thus enabling aging tests. This application utilizes multiple wire grooves or conduits on the insulating plate to constrain multiple acquisition lines, reducing the likelihood of tangling or knotting between the acquisition lines during clip installation. This makes the installation and removal of the clips and acquisition lines more convenient, improving testing efficiency. Furthermore, the acquisition lines and clips can be pre-installed on the insulating plate. When the battery pack undergoes aging tests, only the clips need to be clamped onto the data acquisition terminals. Since the acquisition lines are pre-fixed to the insulating plate, tangling or knotting will not occur during clip installation, further improving the ease of installation and removal of the clips and acquisition lines, and consequently, further improving testing efficiency. In addition, each data acquisition clip in this application corresponds to a through hole on the insulating plate, thereby preventing accidental contact and arcing during installation of the data acquisition clip.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides an auxiliary tooling for battery pack aging testing, including an insulating plate 1, acquisition wires 2, and acquisition clamps 3. The insulating plate 1 has multiple through holes 4 arranged in a matrix. The insulating plate 1 is used to install onto the upper surface of the battery pack 8. The upper surface of the battery pack 8 has multiple acquisition terminals that extend into the through holes 4, and the multiple acquisition terminals correspond one-to-one with the multiple through holes 4. There are multiple acquisition wires 2 and multiple acquisition clamps 3. The insulating plate 1 also has multiple wire grooves or multiple wire tubes 5. The multiple acquisition wires 2 are respectively fixed in the multiple wire grooves or wire tubes 5. One end of the acquisition wire 2 is connected to the acquisition clamp 3, and the other end is used to connect to external testing equipment. The number of acquisition wires 2 and acquisition clamps 3 is equal to the number of through holes 4. The acquisition clamps 3 are set in the through holes 4 and clamped to the acquisition terminals. The multiple acquisition clamps 3 correspond one-to-one with the multiple through holes 4, and each acquisition clamp 3 is connected to one acquisition wire 2.

[0026] In some embodiments of this application, the battery pack 8 is composed of multiple battery modules, each battery module including multiple arrayed battery cells, and multiple battery cells are connected by busbars. The acquisition terminal is fixed on the busbar and electrically connected to the busbar.

[0027] In some embodiments of this application, the insulating plate 1 is a rectangular plate and the through hole 4 is a rectangular hole.

[0028] In some embodiments of this application, the acquisition line 2 is a wire, the acquisition clip 3 is a conductive clip, and the acquisition line 2 and the acquisition clip 3 are electrically connected.

[0029] In the above-mentioned scheme of this application, the auxiliary tooling includes an insulating plate 1, a data acquisition line 2, and a data acquisition clamp 3. The insulating plate 1 has multiple through holes 4 arranged in a matrix. The insulating plate 1 is used to install onto the upper surface of the battery pack 8. The upper surface of the battery pack 8 has multiple data acquisition terminals that extend into the through holes 4. Each of the multiple data acquisition terminals corresponds to one of the multiple through holes 4. There are multiple data acquisition lines 2 and multiple data acquisition clamps 3. The insulating plate 1 also has multiple wire grooves or multiple wire conduits 5. The multiple data acquisition lines 2 are fixed in the multiple wire grooves or wire conduits 5. One end of the data acquisition line 2 is connected to the data acquisition clamp 3, and the other end is used to connect to external testing equipment. The number of data acquisition lines 2 and data acquisition clamps 3 is equal to the number of through holes 4. The data acquisition clamps 3 are set in the through holes 4 and clamped to the data acquisition terminals. Each of the multiple data acquisition clamps 3 corresponds to one of the multiple through holes 4. Each data acquisition clamp 3 is connected to one data acquisition line 2. With this structure, during aging tests of the battery pack 8, the insulating plate 1 can be placed on the upper surface of the battery pack 8, with the multiple acquisition terminals on the upper surface of the battery pack 8 positioned within the multiple through holes 4. Then, the acquisition clamp 3 is clamped onto the acquisition terminals, allowing the electrical energy of the battery pack 8 to be conducted to external testing equipment via the acquisition clamp 3 and the acquisition wires 2, thus enabling aging tests of the battery pack 8. Furthermore, this application uses multiple wire grooves or multiple wire conduits 5 on the insulating plate 1 to constrain the multiple acquisition wires 2, reducing the likelihood of tangling or knotting between the acquisition wires 2 during the installation of the acquisition clamp 3. This makes the installation and removal of the acquisition clamp 3 and the acquisition wires 2 more convenient, improving testing efficiency. Furthermore, the data acquisition line 2 and the data acquisition clip 3 can be pre-installed on the insulating plate 1. When the battery pack 8 undergoes aging testing, the data acquisition clip 3 can simply be clamped onto the data acquisition terminal. Since the data acquisition line 2 is pre-fixed to the insulating plate 1, the data acquisition lines 2 will not become tangled or knotted during the installation of the data acquisition clip 3, thereby further improving the ease of installation and removal of the data acquisition clip 3 and the data acquisition line 2, and thus further improving testing efficiency. In addition, each data acquisition clip 3 in this application corresponds to a through hole 4 on the insulating plate 1, thereby preventing accidental contact and arcing during the installation of the data acquisition clip 3.

[0030] In some embodiments of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the through holes 4 are arranged in N rows and M columns, and the wire grooves or wire tubes 5 are distributed along the length of the insulating plate 1. Each row of through holes 4 has a wire groove or a wire tube 5 on its lower side. With this structure, each row of through holes 4 is provided with a corresponding wire groove or a wire tube 5, which can further optimize the distribution of the acquisition lines 2. The acquisition lines 2 connected to the acquisition terminals in the same row can be bundled into a wire groove or wire tube 5, which can further reduce the probability of the acquisition lines 2 getting tangled and knotted, making the distribution of the acquisition lines 2 more orderly, and further improving the convenience of assembling and disassembling the acquisition clips 3 and the acquisition lines 2.

[0031] In some embodiments of this application, the spacing between any two adjacent through holes 4 in the same row is equal, the spacing between any two adjacent rows of through holes 4 is equal, and the through holes 4 in the first column and the last column are open.

[0032] In some embodiments of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the through holes 4 are arranged in 5 rows and 9 columns, and there are 5 wire grooves or wire tubes 5. With this structure, the acquisition line 2 can be constrained by the 5 wire grooves or wire tubes 5, which improves the orderliness of the distribution of the acquisition line 2.

[0033] In some embodiments of this application, there are 45 through holes 4, 45 acquisition clips 3, and 45 acquisition lines 2. Each through hole 4 contains an acquisition clip 3, each acquisition clip 3 is connected to an acquisition line 2, and each wire groove or wire tube 5 contains 9 acquisition lines 2.

The auxiliary fixture also includes a support 6, which consists of a base rod and a ring.

Using this structure, the conduit 5 is supported by multiple support members 6, which can further improve the stability of the conduit 5 installation.

[0036] In some embodiments of this application, each conduit 5 is provided with 9 support members 6.

[0037] In some embodiments of this application, the spacing between any two adjacent support members 6 is equal along the length of the conduit 5. This structure, where the spacing between any two adjacent support members 6 is equal, can further improve the stability of the conduit 5 installation.

[0038] In some embodiments of this application, the length of the conduit 5 is less than the length of the insulating plate 1.

[0039] In some embodiments of this application, the sidewall of the conduit 5 is provided with multiple perforations, and one end of the acquisition line 2 extends through the perforations and is connected to the acquisition clip 3. With this structure, the acquisition line 2 inside the conduit 5 can extend through the perforations to facilitate connection with the acquisition clip 3. The mutual restraint between the acquisition line 2 and the inner wall of the perforation can further improve the stability of the acquisition line 2 installation.

[0040] In some embodiments of this application, when the insulating plate 1 has a wire groove, the acquisition line 2 is embedded in the wire groove. The auxiliary fixture also includes a U-shaped limiting member, which includes a left rod, an upper rod, and a right rod connected in sequence. The left rod and the right rod are respectively disposed on both sides of the wire groove, and both the left rod and the right rod are fixedly connected to the insulating plate 1. The acquisition line 2 is located between the U-shaped limiting member and the wire groove. With this structure, the acquisition line 2 is limited by the cooperation of the U-shaped limiting member and the wire groove, which can improve the stability of the installation of the acquisition line 2.

[0041] In some embodiments of this application, the wire groove includes a long groove and multiple lead wire grooves. The long groove is arranged along the length of the insulating plate 1, and one end of the lead wire groove is connected to the long groove, while the other end is connected to the through hole 4.

By adopting this structure, each data acquisition terminal is labeled with multiple labels 7, which can improve the installation accuracy of the data acquisition clip 3 and avoid installation errors that affect the accuracy of the test.
