[0053] The embodiments of the present application provide an electronic CAM data table generation method, a winding battery cell processing method and an electronic device, which solve the technical problems of the existing electronic CAM data table generation method, which has low calculation efficiency and causes waste of pole pieces.

[0054] In order to enable those skilled in the art to better understand the method of the present application, the technical method in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] For easier understanding, see Figure 1 , Figure 1 This is a flow chart of Example 1 of a method for generating an electronic cam data table in an embodiment of the present application.

[0056] A method for generating an electronic cam data table in this embodiment includes:

[0057] Step 101: Obtain the material thickness corresponding to the battery core material to be analyzed.

[0058] It is understandable that different battery cells may correspond to different battery cell materials, and in this application, an electronic CAM data table is generated based on the material thickness in the battery cell. Therefore, when generating the electronic CAM data table in this application, the material thickness corresponding to the battery cell material to be analyzed is obtained first.

[0059] Step 102: Based on the material thickness, calculate the increase in the diameter of the corresponding battery cell when the battery cell material to be analyzed is wound one circle.

[0060] The wound battery cell is processed by winding, so in this application, after obtaining the material thickness corresponding to the battery cell material to be analyzed, the increase in the single-turn diameter of the battery cell after the material to be analyzed is wound one turn corresponding to the material thickness can be determined.

[0061] Step 103: Calculate the cell diameters of the cells at different times based on the increase in diameter per single turn.

[0062] After determining the single-turn diameter increase corresponding to the battery material to be analyzed, the battery diameter of the battery at different times can be calculated. It can be understood that the battery diameter in this embodiment is the winding needle diameter and the winding diameter increase, and the winding needle diameter is fixed. In this embodiment, the battery diameter is determined by first determining the winding diameter increase at different times. After calculating the winding diameter increase, the winding diameter increase at different times and the winding needle diameter are summed to obtain the battery diameter at the corresponding time.

[0063] Step 104 : Calculate the winding needle linear speed corresponding to each battery cell diameter using the winding needle angular speed, so as to generate an electronic cam data table when winding the battery cell material to be analyzed.

[0064] When winding a battery cell, the angular velocity of the winding needle is generally fixed over time, so the winding needle linear velocity can be calculated based on the fixed winding needle angular velocity at different times, and then an electronic cam data table for winding the battery cell material to be analyzed is generated. It can be understood that the electronic cam data table in this embodiment includes a number of electronic cam data, wherein the electronic cam data is in the form of: time, winding needle angular velocity, winding needle linear velocity and battery cell diameter, that is, the battery cell diameter and winding needle linear velocity at different times under a fixed winding needle angular velocity.

[0065] In this embodiment, when generating the electronic cam data table, the material thickness of the material to be analyzed is determined. According to the material thickness, the increase in the single-turn diameter of the battery cell when the battery cell material to be analyzed is wound one circle can be known, and based on the single-turn diameter increase, the battery cell diameter at different times can be determined, and then the corresponding winding needle line speed under different battery cell diameters can be calculated based on the battery cell diameter, thereby generating an electronic cam data table for winding the battery cell material to be analyzed. From the above description, it can be seen that the present application no longer generates an electronic cam data table by means of pole piece simulation. Compared with the existing method of generating an electronic cam data table by pole piece simulation, the present application has higher calculation efficiency and will not cause pole piece waste, thereby solving the technical problem of the existing electronic cam data table generation method having low calculation efficiency and causing pole piece waste.

[0066] The above is Example 1 of a method for generating an electronic cam data table provided in an embodiment of the present application. The following is Example 2 of a method for generating an electronic cam data table provided in an embodiment of the present application.

[0067] See also Figure 2 , Figure 2 This is a flow chart of Embodiment 2 of a method for generating an electronic CAM data table in an embodiment of the present application.

[0068] A method for generating an electronic cam data table in this embodiment includes:

[0069] Step 201: When it is determined that the battery cell material on the winding machine has changed, the battery cell material to be analyzed is determined based on the changed battery cell material.

[0070] The electronic CAM data table generation method in the present application is applied to the winding machine, and the corresponding triggering method in the present application is when the battery cell material on the winding machine changes, that is, when the battery cell material on the winding machine changes, it is considered that the battery cell model has changed. At this time, the battery cell material to be analyzed is determined based on the changed battery cell material.

[0071] Changes in battery cell materials refer to changes in the models and specifications of the battery cell materials. However, for conventional battery cell material replenishment (i.e. replenishing the used battery cell materials with the same battery cell materials), there is no change in the battery cell materials.

[0072] It should be noted that the battery cell materials to be analyzed include: anode sheet materials, cathode sheet materials and diaphragm materials. It is understandable that the battery cell materials wound on the winding machine also include anode sheet materials, cathode sheet materials and diaphragm materials. When at least one of the three is changed, it is considered that the battery cell materials have changed. At this time, the changed battery cell materials and the unchanged battery cell materials are both used as the battery cell materials to be analyzed, that is, when only the cathode sheet material is changed, the changed cathode sheet material and the unchanged anode sheet material and diaphragm material are used as the battery cell materials to be analyzed.

[0073] Step 202: Obtain the input thickness of the battery material to be analyzed input by the user.

[0074] After the cell material to be analyzed is determined in step 201, the input thickness of the cell material to be analyzed is determined. It can be understood that since the cell material to be analyzed includes multiple cell materials, the input thickness corresponding to each cell material is obtained at this time.

[0075] Step 203: Obtain the actual thickness of the battery material to be analyzed.

[0076] In order to ensure the accuracy of the material thickness of the battery cell material to be analyzed in this embodiment, the material thickness is clarified by comparing the actual thickness with the input thickness. Therefore, the actual thickness is determined while determining the input thickness of the battery cell material to be analyzed. It can be understood that the actual thickness in this embodiment is also the actual thickness corresponding to each battery cell material.

[0077] It can be understood that the actual thickness can be obtained by actually calculating after taking an image of the battery cell material to be analyzed by a camera; or the actual thickness corresponding to different battery cell materials can be stored in a storage module in the winding machine, and the corresponding actual thickness can be directly retrieved through the material signal of the battery cell material during specific use.

[0078] Step 204 , determining whether the actual thickness is consistent with the input thickness, if so, taking the input thickness as the material thickness corresponding to the battery material to be analyzed, if not, taking the actual thickness as the material thickness corresponding to the battery material to be analyzed.

[0079] Specifically, when comparing the actual thickness and the input thickness, if the actual thickness and the input thickness are consistent, the input thickness is used as the material thickness corresponding to the battery cell material to be analyzed; if the actual thickness and the input thickness are inconsistent, the actual thickness is used as the material thickness corresponding to the battery cell material to be analyzed.

[0080] Step 205: Based on the material thickness corresponding to each material, calculate the increase in the single-turn diameter of the corresponding battery cell when the material is wound one turn.

[0081] Specifically, in this embodiment, based on the material thickness corresponding to each material, the increase in the single-turn diameter of the corresponding battery cell when the material is wound one turn can be calculated as follows:

[0082] Based on the material thickness d1 of the anode sheet material, the increase in the diameter of the corresponding battery cell when the anode sheet material is wound one circle is calculated to be 2d1;

[0083] Based on the material thickness d2 of the cathode sheet material, the increase in the diameter of the corresponding battery cell when the cathode sheet material is wound one circle is calculated to be 2d2;

[0084] Based on the material thickness d3 corresponding to the diaphragm material, the increase in the single-turn diameter of the corresponding battery cell when the diaphragm material is wound one turn is calculated to be 4d3.

[0085] It can be understood that the thickness of each material in the battery cell material to be analyzed will increase by two times after winding one circle when it is a single layer, and the layer ratio of the anode sheet material, cathode sheet material and separator material in the battery cell material to be analyzed is 1:1:2, so the increase in the single-circle diameter of each material in the battery cell material to be analyzed after winding one circle is 2d1, 2d2, and 4d3.

[0086] Step 206: Determine the number of windings of each material in the battery core material at different times.

[0087] In this embodiment, determining the number of windings of each material in the battery core material at different times specifically includes:

[0088] Determine the initial winding angle corresponding to each material in the battery core material to be analyzed;

[0089] Obtain the rotation angle of each material in the battery material to be analyzed at different times;

[0090] According to the initial winding angle and the rotation angle corresponding to each material in the materials to be analyzed, the number of winding turns of each material at different times is calculated.

[0091] Specifically, the number of winding turns N is = (rotation angle - initial winding angle) / 360°.

[0092] Step 207: Calculate the increase in winding diameter of each material at different times according to the number of winding turns and the increase in diameter per turn corresponding to each material.

[0093] After clarifying the increase in diameter of each material after winding one circle and the number of winding circles at different times, the increase in winding diameter of each material at different times can be determined. For example, if the number of winding circles corresponding to the anode sheet material at time t1 is 2 circles, then the corresponding increase in winding diameter is: 2*2d1. It can be understood that the increase in winding diameter corresponding to the cathode sheet material and the diaphragm material can also be calculated by the aforementioned example, which will not be repeated in this embodiment.

[0094] Step 208: Calculate the cell diameters of the cells at different times by comprehensively considering the winding needle diameter and the increase in the winding diameter of each material at different times.

[0095] After determining that at different times, the increase in winding diameter corresponding to the anode sheet material is D1, the increase in winding diameter corresponding to the cathode sheet material is D2, and the increase in winding diameter corresponding to the diaphragm material is D3, the total increase in winding diameter can be determined by combining the sum of the three, and then the sum of the three and the winding needle diameter are added to obtain the cell diameter of the battery cell at different times.

[0096] Step 209: Obtain the angular velocity of the winding needle when winding the material to be analyzed.

[0097] Step 210: Calculate the winding needle linear velocity corresponding to each cell diameter using the first relationship corresponding to the winding needle angular velocity.

[0098] Among them, the first relationship is:

[0099] Winding needle angular velocity = 360° × winding needle linear velocity / (actual diameter of battery cell × π).

[0100] Step 211, comprehensively consider the winding needle angular velocity, the cell diameter at different times, and the winding needle linear velocity to generate an electronic CAM data table when winding the cell material to be analyzed.

[0101] In this embodiment, when generating the electronic cam data table, the material thickness of the material to be analyzed is determined. According to the material thickness, the increase in the single-turn diameter of the battery cell when the battery cell material to be analyzed is wound one circle can be known, and based on the single-turn diameter increase, the battery cell diameter at different times can be determined, and then the corresponding winding needle line speed under different battery cell diameters can be calculated based on the battery cell diameter, thereby generating an electronic cam data table for winding the battery cell material to be analyzed. From the above description, it can be seen that the present application no longer generates an electronic cam data table by means of pole piece simulation. Compared with the existing method of generating an electronic cam data table by pole piece simulation, the present application has higher calculation efficiency and will not cause pole piece waste, thereby solving the technical problem of the existing electronic cam data table generation method having low calculation efficiency and causing pole piece waste.

[0107] In this embodiment, when processing the battery cell to be wound, the electronic cam data table corresponding to the battery cell to be wound can be determined, and then the battery cell to be wound can be processed using the electronic cam data table.
