Description

Technical Field

[0001] This utility model relates to the field of retired lithium battery technology, and in particular to a rapid sorting device for retired lithium batteries. Background Technology

[0002] With increasing global energy consumption and severe environmental pollution, green transportation tools, represented by electric vehicles, have gained significant attention due to their high efficiency and low pollution. Lithium-ion batteries are a crucial power source for electric vehicles. When the performance of an electric vehicle's power battery drops to 80% of its original performance, it is considered a retired battery and no longer suitable for use in electric vehicles. However, retired batteries can still exhibit good performance at lower rates. Recycling these retired batteries would result in substantial waste; therefore, a tiered recycling system could be considered. Due to variations in self-discharge rates and ambient temperatures among individual cells in a power battery pack, retired power batteries exhibit inconsistencies in capacity, internal resistance, and voltage, as well as differences in the degree of aging among individual cells. Therefore, it is necessary to screen each individual cell within the power lithium-ion battery pack to efficiently utilize each cell.

[0003] To improve the sorting efficiency of lithium-ion power batteries and adapt to grouping under different operating conditions, the following methods are currently used for sorting and reorganizing retired lithium batteries: Firstly, based on thermal behavior, a self-organizing map (SOM) model belonging to an artificial neural network is built to sort nickel-metal hydride batteries, classifying them into high-heat, medium-heat, and low-heat batteries. Secondly, a convolutional neural network based on two-step time series clustering (TTSC) is used to sort individual cells. Thirdly, maximum capacity and equivalent impedance spectrum are selected as sorting indicators. However, these methods are time-consuming and costly, have low sorting efficiency, and are not suitable for the rapid sorting of large batches of retired lithium batteries. Utility Model Content

[0051] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0052] like Figure 1-2 As shown, the rapid sorting device for retired lithium batteries proposed in this embodiment includes a support platform 1, and further includes components mounted on the support platform 1:

[0053] Adjustment component 2, used to support the lithium battery, is slidably connected to the upper surface of support platform 1 via movable component 3;

[0054] Information acquisition device 4, located above adjustment component 2, collects surface information of lithium battery and determines the positive and negative electrode positions of lithium battery;

[0055] The testing device 5 is connected to the positive and negative terminals of the lithium battery, measures the current in the lithium battery, calculates the charging and discharging speed of the lithium battery, and compares the internal capacity with the sample set.

[0056] Both the information acquisition device 4 and the detection device 5 are fixed to the support platform 1 by an inverted L-shaped fixing bracket 6, ensuring the stability of the information acquisition device 4 and the detection device 5.

[0057] The storage component 7 includes multiple storage plates 702 for storing batteries of different capacities after sorting.

[0058] In this way, by adjusting component 2, the position of the lithium battery can be adjusted so that the positive and negative terminals of the lithium battery correspond to the detection device 5, avoiding manual adjustment and reducing the workload of the staff. At the same time, it avoids the problem of incorrect connection of the detection device 5 to the positive and negative terminals of the lithium battery (incorrect connection will not only cause the current direction to be reversed, and the detection device will not be able to measure the current value of the battery correctly, resulting in inaccurate measurement results, but will also cause short circuit or overload, thereby damaging the detection device, and in severe cases, even causing safety risks such as short circuit and fire).

[0059] The testing device 5 is connected to the positive and negative terminals of the lithium battery, measures the current in the lithium battery, calculates the charging and discharging speed of the lithium battery, and compares the internal capacity with the sample set. Based on the obtained internal capacity of each lithium battery, lithium batteries with the same charging and discharging speed and the same internal resistance are placed on the corresponding storage plate 702 for recombination, completing the rapid sorting and recombination of retired lithium batteries. This not only avoids the problem of inconsistent capacity, internal resistance, and voltage of retired power batteries due to differences in self-discharge levels, ambient temperature, and other factors during use, which can lead to local overheating of the battery pack, accelerate battery aging and damage, and increase the risk of fire, but also eliminates the need for manual sorting, making it suitable for the rapid sorting of large batches of retired lithium batteries and improving sorting efficiency.

[0060] Furthermore, a movable compartment 101 extending along its length is provided in the center of the support platform 1, and the moving component 3 includes:

[0061] The first driving component 301 is fixed to the inner wall of the end of the movable compartment 101;

[0062] The threaded rod 302 is connected to the output shaft of the first driving component 301;

[0063] The movable block 303 is provided with internal threads and is threadedly connected to the threaded rod 302.

[0064] The connecting rod 304 is fixed at one end to the moving block 303 and at the other end to the adjusting component 2.

[0065] The first driving component 301 can be a servo motor. When the servo motor is started, the threaded rod 302 is rotated. The rotational motion is converted into linear motion, which drives the moving block 303 to move along the axial direction of the threaded rod 302. This, in turn, drives the adjustment component 2 to move as a whole, so as to adjust the position of the lithium battery on the adjustment component 2, so that the information acquisition device 4 can accurately collect the surface information of the lithium battery.

[0066] Furthermore, the adjustment to component 2 includes:

[0067] The lower end of the placement platform 201 is fixed to the end of the connecting rod 304, and the upper middle part has a receiving groove 2011 that passes through the upper end surface;

[0068] Support plate 202 is rotatably mounted on placement platform 201;

[0069] The support plate 202 has a locking block 2021 fixed to its lower surface, and the placement platform 201 has a locking groove 2012 on its upper surface. The locking block 2021 is engaged in the locking groove 2012, and both the locking block 2021 and the locking groove 2012 are annular. This guides the rotation of the support plate 202 and ensures the rotational stability of the support plate 202 on the placement platform 201.

[0070] The second driving component 203 is fixed to the bottom wall of the receiving groove 2011, and its output shaft is fixed to the lower end of the support plate 202, driving the support plate 202 to rotate. Specifically, the second driving component 203 can be a drive motor. The specific structure can be referred to the existing structure, and will not be repeated in this article.

[0071] The placement plate 204 includes a first side, a connecting part, and a second side, forming a U-shaped structure, and is movably connected to the support plate 202;

[0072] Furthermore, it also includes a pushing mechanism for pushing the placement plate 204 above the storage assembly 7, the pushing mechanism comprising:

[0073] The first fixing plate 2022 is fixed on the support plate 202;

[0074] The first push rod 2023 has one end fixed to the side of the first fixed plate 2022 and the other end fixed to the outer side of the connecting part.

[0075] This facilitates the storage of the sorted lithium batteries on the corresponding storage plate 702 within the storage assembly 7. Specifically, the first push rod 2023 can be configured as an electric push rod structure; the specific structure can be referenced from existing structures and will not be repeated here.

[0076] The lower surface of the placement plate 204 is fixed with a second slider 2041, and a second groove is provided on the support plate 202. The second slider 2041 is slidably connected in the second groove. In this way, the movement of the placement plate 204 is guided, so that the placement plate 204 is smoothly pushed above the storage component 7, ensuring the stability of the movement of the placement plate 204.

[0077] The clamping assembly includes a first clamping plate 206 and a second clamping plate 209 located on a first side and a second side, respectively, a first driving mechanism and a second driving mechanism for driving the first clamping plate 206 and the second clamping plate 209 to bring the first clamping plate 206 and the second clamping plate 209 closer to or further away from each other, thereby clamping or releasing the lithium battery.

[0078] Specifically, the first driving mechanism is configured as a second push rod 207, and the second driving mechanism is configured as a third push rod 210. A second fixing plate 205 is fixed on the first side outside the first clamping plate 206, and the second push rod 207 is installed between the second fixing plate 205 and the first clamping plate 206. A third fixing plate 208 is fixed on the second side outside the second clamping plate 209, and the third push rod 210 is installed between the third fixing plate 208 and the second clamping plate 209. Thus, the second push rod 207 and the third push rod 210 can control the movement of the first clamping plate 206 and the second clamping plate 209 respectively, causing them to move closer or further apart, thereby clamping or releasing the lithium battery. This control is convenient and fast. Specifically, the second push rod 207 and the third push rod 210 can be configured as electric push rods; specific structures can be referenced from existing structures and will not be repeated here.

[0079] To ensure the stability of the adjustment component 2's movement on the support platform 1, a guide structure 8 is provided between the placement platform 201 and the support platform 1. The guide structure 8 includes a first slider 801 fixed to the lower end of the placement platform 201 and a first groove 802 formed on the upper surface of the support platform 1. The first slider 801 is slidably connected within the first groove 802. Specifically, this guide structure can be configured in two sets, symmetrically arranged on the front and rear sides of the movable compartment 101.

[0080] In this embodiment, the tail end of the support platform 1 is provided with an L-shaped groove 102. The storage component 7 is located in the L-shaped groove 102 and includes a placement slot 701. Each storage plate 702 and the bottom wall of the placement slot 701 are provided with a lifting mechanism 703. Multiple lifting mechanisms 703 correspond one-to-one with multiple storage plates 702. Multiple storage plates 702 are evenly arranged in the placement slot 701.

[0081] Specifically, the lifting mechanism 703 can be set as a lifting cylinder or an electric cylinder, etc. The specific structure can be referred to the existing structure, and will not be repeated in this article.

[0082] In this way, the height of each storage plate 702 can be controlled individually, which makes it easier to store lithium batteries of the corresponding capacity of the storage plate 702 and improves the efficiency of sorting retired lithium batteries.

[0083] Working principle: First, place the retired lithium battery rapid sorting device in this embodiment in a suitable position, then connect the device to an external power supply. Then, the staff places the lithium battery on the support plate 202. Subsequently, the information acquisition device 4 collects the surface information of the lithium battery and determines the position of the positive and negative electrodes. Then, the second driving component 203 is activated to drive the support plate 202 to rotate. The support plate 202 drives the lithium battery to rotate, thereby adjusting the position of the positive and negative electrodes of the lithium battery. After the adjustment is completed, the staff can use the second push rod 207 and the third push rod 210 to drive the first clamping plate 206 and the second clamping plate 209 to move closer to each other to clamp and fix the lithium battery.

[0084] Then, the first driving component 301 is started, which drives the threaded rod 302 to rotate. The threaded rod 302 drives the moving block 303 to move. The moving block 303 drives the connecting rod 304 to move synchronously, thereby driving the adjustment component 2 holding the lithium battery to move. When the lithium battery moves to below the detection device 5, the first driving component 301 stops operating. The detection device 5 connects to the positive and negative terminals of the test lithium battery to measure the current in the lithium battery, calculates the charging and discharging speed of the lithium battery, and compares the sample set to obtain the internal capacity of the lithium battery.

[0085] Based on the obtained internal capacity of the lithium battery, it is determined that the lithium battery is placed on the surface of the corresponding storage plate 702. The first driving component 301 continues to start, driving the lithium battery to move. When the lithium battery moves to the appropriate position, the first push rod 2023 is activated to push the placement plate 204 to move. When the placement plate 204 moves above the corresponding storage plate 702, the lifting mechanism 703 is activated to drive the corresponding storage plate 702 to the lower surface of the lithium battery. At the same time, the second push rod 207 and the third push rod 210 drive the first clamping plate 206 and the second clamping plate 209 to move away from the lithium battery, thus completing the sorting of the lithium battery.

[0086] It should be noted that the method of using the retired lithium battery rapid sorting device in this embodiment is as follows;

[0087] Step 1: Select lithium batteries with capacities of 100%, 60%, 40%, and 20% as test samples. Measure the current in the test samples by connecting the positive and negative terminals of the test lithium batteries, calculate the charging and discharging speed and internal resistance of the lithium batteries under different capacities, and create a sample set.

[0088] Step 2: Place the lithium battery on the surface of the support plate 202 and clamp it with the clamping assembly. Then, the information acquisition device 4 collects the surface information of the lithium battery and marks the positive and negative positions on the surface of the lithium battery. Then, control the second driving component 203 to rotate the lithium battery so that the positive and negative terminals of the lithium battery are adjusted to the specified positions.

[0089] Step 3: Control the operation of the first driving component 301 to drive the threaded rod 302 to rotate. The threaded rod 302 drives the moving block 303 to move, and at the same time drives the connecting rod 304 to move synchronously, thereby driving the adjustment component 2 holding the lithium battery to move. When the lithium battery moves to below the detection device 5, the first driving component 301 stops operating. The detection device 5 connects to the positive and negative terminals of the test lithium battery to measure the current in the lithium battery, calculates the charging and discharging speed of the lithium battery, and compares the sample set to obtain the internal capacity of the lithium battery.

[0090] Step 4: Based on the internal capacity of the lithium battery obtained in Step 3, determine the surface of the corresponding storage plate 702 where the lithium battery is placed. The first driving component 301 continues to operate, driving the lithium battery to move. When the lithium battery moves to the appropriate position, the first push rod 2023 pushes the placement plate 204 to move. When the placement plate 204 moves above the corresponding storage plate 702, the lifting mechanism 703 drives the storage plate 702 to move to the lower surface of the lithium battery, and at the same time, the clamping component releases the lithium battery.

[0091] This allows for quick adjustment of the lithium battery's position, facilitating subsequent testing, sorting of lithium-ion power batteries, and recombination of batteries with different capacities.
