Description

Technical Field

[0001] This utility model relates to the technical field of batteries, and in particular to an integrated module acquisition unit. Background Technology

[0002] Integrated module acquisition units are commonly used to monitor the status of battery module cells inside the battery. They can detect the voltage and temperature information of the cells and establish a high-voltage tight connection between the cells. In existing battery module acquisition units, blister trays or injection-molded brackets are commonly used as support components. The electrode plates are fixed by heat fusion or riveting. The wiring harness is generally connected and fixed with cable ties in conjunction with the support components or brackets. The excess part of the cable ties needs to be removed later. These processes increase the assembly process of the entire battery module, affect efficiency, and increase the difficulty of battery repair. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an integrated module acquisition unit to solve the problem of battery module assembly process affecting production efficiency.

[0004] Based on the technical problems existing in the background art, this utility model proposes an integrated module acquisition unit, including a battery module with multiple cells. Both ends of the battery module are equipped with bracket assemblies. Multiple sets of electrode plates connected to the cell terminals are fixed in the bracket assemblies by buckles. An acquisition unit capable of detecting electrode plate voltage information and cell temperature information is installed in the bracket assembly.

[0005] In the above solution, the bracket assembly is equipped with multiple clips, which facilitates the fixing of the electrode plates during installation and the connection of the wire harness. This reduces the use of cable ties and rivets, and avoids complicated installation.

[0006] Preferably, the support assembly includes a frame, an insulating sheet, and a mica sheet. The insulating sheet is fixedly connected to the frame by screws and forms a cavity to protect the electrode. The mica sheet is bent and adhered to the insulating sheet and the battery module. The mica sheet has an opening that allows the acquisition unit to be exposed.

[0007] Preferably, the frame is provided with multiple mounting slots for mounting electrode plates. Adjacent mounting slots are isolated by limiting ribs. Each mounting slot has a connection hole in the middle that communicates with the battery module. The electrode post of the battery cell extends through the connection hole into the mounting slot. Each mounting slot is equipped with an electrode plate that abuts against the electrode post.

[0008] In the above scheme, the mounting slots within the frame provide mounting space for the electrodes, which can organize the mounting positions of the electrodes and facilitate the fixing of the electrodes to the terminals of the battery cell.

[0009] Preferably, each mounting slot has a locking buckle on its limiting rib, which can be used to lock and limit the electrode when it is installed in the corresponding mounting slot.

[0010] In the above solution, each mounting slot is provided with multiple clips. When the electrode is installed in the corresponding mounting slot, it can be fixed by the clips, avoiding the use of rivets, which facilitates the disassembly or installation of the electrode and reduces maintenance costs.

[0011] Preferably, each set of frames is provided with a set of acquisition slots, and the limiting ribs of each set of mounting slots have a passageway communicating with the acquisition slots. Each electrode is connected to a voltage acquisition nickel sheet, and the voltage acquisition nickel sheet is connected to the acquisition unit through a voltage acquisition wire harness, which passes through the passageway.

[0012] Preferably, a clamp is provided on the passage, and multiple limiting clamps are provided in the acquisition slot, so that the voltage acquisition cable bundle can be managed through the clamp and the limiting clamp.

[0013] In the above solution, the voltage acquisition harness can be clamped and organized using clips and limit clips, reducing the use of cable ties and improving assembly efficiency.

[0014] Preferably, the frame is provided with a pressure relief hole that connects to the collection slot.

[0015] Preferably, each electrode has a welding groove on the side away from the battery cell for welding a corresponding electrode post. The welding groove has a welding hole that penetrates the electrode. When the back of the mounting groove of the electrode post and the electrode post of the battery cell are in contact, the electrode post and the battery cell can be connected by laser welding from the mounting groove.

[0016] In the above scheme, the welding holes in the welding groove facilitate personnel to connect the electrode post, and the electrode post also has holes corresponding to the welding holes, which can be matched one by one to adjust the position of the electrode.

[0017] Preferably, a temperature sensing groove is also provided inside the frame, and the acquisition unit is connected to a temperature sensor through a temperature sensing acquisition harness. The temperature sensor is located inside the temperature sensing groove.

[0018] In the above scheme, the temperature sensing slot can provide an installation position for the temperature sensor, which facilitates the sensor to detect the temperature inside the battery cell in real time, and then transmits the temperature to the acquisition unit through the temperature sensing acquisition harness.

[0019] Preferably, the thickness of the electrode is less than the depth of the mounting groove.

[0020] In the above scheme, after the electrode is installed, the flatness of the mounting groove needs to be maintained to avoid the electrode protruding from the mounting groove and affecting the flatness of the battery.

[0021] Compared with existing technologies, the integrated module acquisition unit proposed in this utility model adopts the above-mentioned technical solution and achieves the following technical effects:

[0022] This invention simplifies the installation of electrode plates and wiring harnesses, improving the efficiency of the entire battery module installation. In this invention, the electrode plates can be fixed by snap-fit, reducing the use of rivet tools and allowing for planned fixing of the wiring harness, which improves internal cleanliness and facilitates cell maintenance.

Support assemblies 2 are installed at both ends of the battery module 1. Multiple sets of electrode plates 3 connected to the terminals of the battery cells 100 are fixed within the support assembly 2 via buckles 5. An acquisition unit 4 is installed within the support assembly 2 to detect the voltage information of the electrode plates 3 and the temperature information of the battery cells 100. In this solution, the battery module 1 contains multiple battery cells 100, and one electrode plate 3 can correspond to the terminals of multiple battery cells 100. Each electrode plate 3 has an individual voltage, which can be collected by the acquisition unit 4. In this solution, the electrode plates 3 are fixed by buckles 5, reducing the use of rivets, improving convenience, and thus improving efficiency.

[0034] In the specific factual manner, refer to Figure 1 , Figure 2 The support assembly 2 includes a frame 21, an insulating sheet 22, and a mica sheet 23. The insulating sheet 22 is fixedly connected to the frame 21 by screws 24 and forms a cavity to protect the electrode 3. The mica sheet 23 is bent and adhered to the insulating sheet 22 and the battery module 1. The mica sheet 23 has an opening 15 that allows the acquisition unit 4 to be exposed. In this solution, the frame 21 is made of insulating material, such as plastic. The acquisition unit 4 and the electrode 3 are installed in the frame 21 and then sealed and protected by the insulating sheet 22 and the mica sheet 23. The opening 15 on the mica sheet 23 facilitates the acquisition unit 4 to make electrical connections to transmit temperature and voltage signals.

[0035] In the specific factual manner, refer to Figure 4 The frame 21 has multiple mounting slots 211 for mounting the electrode 3. Adjacent mounting slots 211 are separated by limiting ribs 212. Each mounting slot 211 has a connection hole 213 in the middle that communicates with the battery module 1. The electrode post of the cell 100 extends through the connection hole 213 into the mounting slot 211. Each mounting slot 211 has an electrode 3 that abuts against the electrode post. In this solution, the mounting slot 211 can isolate each electrode 3 and provide an installation position for the electrode 3. The length and width of each mounting slot 211 are slightly larger than the length and width of the electrode 3. After the electrode 3 is installed, it can keep the electrode 3 stable. At the same time, the depth of the mounting slot is greater than the thickness of the electrode 3, which can keep the side of the frame 21 away from the cell 100 flat after the electrode 3 is installed.

[0036] In the specific factual manner, refer to Figure 4 , Figure 5Each mounting slot 211 has a locking rib 212 with a buckle 5.

The electrode 3 is square. Each mounting slot 211 has four sides and four locking ribs 212. The middle part of the locking rib 212 with the buckle 5 can be more stable when locking the electrode 3.

[0037] In the specific factual manner, refer to Figure 4 , Figure 5 Each frame 21 has a set of acquisition slots 214. The limiting ribs 212 of each set of mounting slots 211 have a passage 215 that communicates with the acquisition slots 214. Each electrode 3 is connected to a voltage acquisition nickel sheet 41. The voltage acquisition nickel sheet 41 is connected to the acquisition unit 4 through a voltage acquisition wire harness 42. The voltage acquisition wire harness 42 passes through the passage 215. In this scheme, the voltage acquisition nickel sheet 41 needs to be welded and fixed to the surface of the electrode 3 to achieve a stable connection. The voltage acquisition nickel sheet 41 can transmit data to the acquisition unit 4 through the voltage acquisition wire harness 42, and then the acquisition unit 4 transmits the data.

The voltage acquisition wire harness 42 can be managed through the clip 216 and the limiting clips 217. In this scheme, multiple limiting clips 217 and clips 216 with planned paths are set between the voltage acquisition nickel sheet 41 and the acquisition unit 4, which can facilitate the clamping and management of the wire harness.

[0039] In the specific factual manner, refer to Figure 4 The frame 21 is provided with a pressure relief hole 218 that connects to the collection slot 214; in this solution, the pressure relief hole 218 provides pressure relief for the entire cell 100, so as to prevent the battery module 1 from exploding when the cell 100 is in a deflagration.

[0040] In the specific factual manner, refer to Figure 5 Each electrode 3 has a welding groove 31 for welding a corresponding electrode post on the side away from the battery cell 100. The welding groove 31 has a welding hole 32 that penetrates the electrode 3. When the electrode post is in contact with the back of the mounting groove 211 of the electrode 3, the welding hole 32 can be passed through the mounting groove 211 to weld the electrode post and the electrode 3 together. In this solution, the welding groove 31 of the electrode 3 facilitates the positioning of personnel. Personnel can use the welding groove 31 and the welding hole 32 to match the round hole on the electrode post for positioning, which facilitates the adjustment of the position of the electrode 3 and makes it convenient for personnel to use laser welding to weld the electrode 3 and the electrode post.

[0041] In the specific factual manner, refer to Figure 6The frame 21 also has a temperature sensing groove 219. The acquisition unit 4 is connected to a temperature sensor 44 through a temperature sensing acquisition harness 43. The temperature sensor 44 is located in the temperature sensing groove 219.
