Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0061] like Figure 1 As shown in the figure, this application provides a battery cell heat treatment apparatus, including:

[0062] Multiple heating zones, each equipped with a heating component 101, with each heating zone used to heat different parts of the battery cell;

[0063] Temperature sensing component 103 is used to measure the temperature of the battery cell in the temperature sensing zone;

[0064] The controller 104 is connected to the temperature measuring component 103; it is used to output a delivery command based on the temperature of the battery cell when the temperature of the battery cell transmitted by the temperature measuring component is obtained.

[0065] The transport component 105 is connected to the controller 104 and is used to transport the battery cell between multiple heating zones and temperature measuring zones according to the transport mode corresponding to the transport instruction.

[0066] Exemplarily, the transport assembly may include a tray for carrying the battery cells and a moving component that drives the tray to move. The moving component may be a common component for transmitting, supporting, and controlling motion, such as a cylinder, bearing, gear, connector, slider, or guide rail; this application does not limit the specific form of the moving component. The moving component drives the tray to move between the heating zone and the temperature measuring zone, and the battery cells, carried on the tray, move with the tray between the heating zone and the temperature measuring zone.

[0067] Specifically, the transport component moves the battery cell between multiple heating zones and temperature measuring zones according to the transport mode corresponding to the transport instruction. In some examples, the transport component may also be called a transmission mechanism. The transport instruction is generated by the controller based on the temperature of the battery cell in the temperature measuring zone. Specifically, the controller obtains the temperature of the battery cell transmitted by the temperature measuring component and determines the heating mode for the battery cell based on the temperature. The heating mode may include transporting the battery cell to a certain heating zone, heating it for a preset time, and then transporting it to the next heating zone (heating for a preset time), or transporting it to the temperature measuring zone to remeasure the temperature. Based on the heating mode corresponding to the battery cell, the corresponding transport instruction and the corresponding transport mode are obtained. The transport mode may include transporting the battery cell to a certain heating zone, staying there for a preset time, and then transporting it to the next heating zone (staying there for a preset time), or transporting it to the temperature measuring zone.

[0068] The heating zone is equipped with heating components, and different heating zones are used to heat different parts of the battery cell. In some examples, the heating components may also be called heating modules. Exemplarily, the heating components can be components used to provide heating power, converting electrical energy, chemical energy, or other forms of energy into heat energy to achieve the purpose of heating or warming the battery cell. Optionally, the heating components can be electromagnetic heating coils.

[0069] The temperature measurement zone is equipped with a temperature measuring component for measuring the temperature of the battery cell located within the zone. Exemplarily, the temperature measuring component can be a temperature sensor capable of acquiring the battery cell temperature. Optionally, the temperature sensor employs a non-contact temperature acquisition function to obtain the workpiece's temperature data. In a specific embodiment, the temperature sensor can be an infrared temperature sensor.

[0070] This application provides a battery cell heat treatment device, which includes multiple heating zones equipped with heating components. Each heating zone heats different parts of the battery cell. A temperature measuring component measures the temperature of the battery cell in the measuring zone. A controller, connected to the temperature measuring component, outputs a transport command based on the battery cell temperature transmitted by the temperature measuring component. A transport component, connected to the controller, transports the battery cell between the multiple heating zones and the temperature measuring zone according to the transport mode corresponding to the transport command. This ensures that the battery cell temperature does not drop during long-term line shutdowns, avoiding impact on production line efficiency.

[0071] In one embodiment, the heating zone includes a first heating zone and a second heating zone, wherein the first heating zone is used to heat the edge portion of the battery cell, and the second heating zone is used to heat the center portion of the battery cell.

[0072] Specifically, taking a rectangular battery cell as an example, such as... Figure 2 As shown, different parts of the battery cell can be heated by adjusting the relative positions of the heating components and the battery cell. For example, the first heating zone has two heating components, respectively located at the edges of the battery cell, which in some examples may also be referred to as the two wings of the battery cell. The second heating zone has one heating component located at the center of the battery cell. In specific application scenarios, those skilled in the art can adjust the positions of the heating components to heat different parts of the battery cell, depending on the shape and size of the battery cell and the specific heating requirements of the battery cell.

[0073] This application provides a battery cell heat treatment device that heats the center and edge of the battery cell by setting a first heating zone and a second heating zone, respectively, and uses a conveying component to move the battery cell between the first heating zone and the second heating zone, thereby achieving heating of each part and achieving the effect of heat preservation of the battery cell.

[0074] In one embodiment, the first heating zone is provided with two sets of heating components located on both sides of the battery cell, or one set of heating components located on one side of the battery cell; each set of heating components includes at least two heating components for heating the edge portion of the battery cell.

[0075] Specifically, taking a transport component including a tray and a thin-film battery cell as an example, the battery cell moves between a first heating zone and a second heating zone as the tray moves. The first heating zone may be equipped with two sets of heating components located on both sides of the battery cell, for example, such as... Figure 3 As shown, the two sets of heating components can be located on the upper and lower sides of the battery cell, respectively. When the battery cell has other shapes, or the transport component is a different type of part, the two sets of heating components can also be located on the left and right sides, front and rear sides, etc., of the battery cell. Optionally, the first heating zone can also be provided with a set of heating components located on one side of the battery cell. Figure 4 and Figure 5 As shown, the heating element can be located on the upper or lower side of the battery cell. When the battery cell has other shapes, or the transport assembly is a different type of component, the heating element can also be located on the left, right, front, or rear side of the battery cell.

[0076] Furthermore, each group of heating components in the first heating zone includes at least two heating components for heating the edge portion of the battery cell. Specifically, the distance between the two heating components is set according to parameters such as the shape and size of the battery cell being heated, so as to achieve the purpose of heating the edge portion or the two wings of the battery cell.

[0077] In one embodiment, the second heating zone is provided with two sets of heating components located on both sides of the battery cell, or one set of heating components located on one side of the battery cell; each set of heating components includes at least one heating component for heating the central part of the battery cell.

[0078] Specifically, taking a transport component including a tray and a thin-film battery cell as an example, the battery cell moves between a first heating zone and a second heating zone as the tray moves. The second heating zone may be equipped with two sets of heating components located on both sides of the battery cell, for example, such as... Figure 3 As shown, the two sets of heating components can be located on the top and bottom sides of the battery cell, respectively. When the battery cell has other shapes, or the transport components are other types of parts, the two sets of heating components can also be located on the left and right sides, front and back sides, etc., of the battery cell. Optionally, the second heating zone can also be provided with a set of heating components located on one side of the battery cell. Figure 4 and Figure 5 As shown, the heating element can be located on the upper or lower side of the battery cell. When the battery cell has other shapes, or the transport assembly is a different type of component, the heating element can also be located on the left, right, front, or rear side of the battery cell.

[0079] Furthermore, each group of heating components in the second heating zone includes at least one heating component for heating the central portion of the battery cell. Specifically, the position of the heating component is set according to parameters such as the shape and size of the battery cell being heated, in order to achieve the purpose of heating the central portion of the battery cell.

[0080] The battery cell heat treatment equipment provided in this application embodiment can flexibly set the number and position of heating components in the first heating zone and the second heating zone according to the shape, material, size and other parameters of the battery cell to be heated, so as to better achieve uniform heating of the battery cell.

[0081] In one embodiment, such as Figure 6 As shown, a method for controlling the heat treatment of battery cells is provided. This embodiment illustrates the application of this method to the battery cell heat treatment equipment described above. It is understood that this method can also be applied independently to a terminal or server, or to a system including both a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0082] Step 602: Obtain the cell temperature in the temperature measurement area.

[0083] Specifically, the controller obtains the cell temperature in the temperature measurement zone through a temperature sensing component. For example, in response to receiving an instruction to enter the heat preservation mode, the controller begins executing the cell heat treatment control method provided in this application embodiment. The heat preservation mode instruction can be manually triggered; when a production line malfunctions, leading to unexpected situations such as prolonged line stoppage, the battery cell heat treatment equipment can be manually instructed to enter the heat preservation mode.

[0084] Step 604: Based on the cell temperature, output a transport command; the transport command is used to instruct the transport component to transport the cell according to the corresponding transport mode.

[0085] Specifically, the controller outputs a transport command to the transport component based on the cell temperature. This transport command instructs the transport component to transport the cell according to a corresponding transport mode. Specifically, the controller determines the heating mode for the cell based on its temperature. The heating mode may include transporting the cell to a heating zone, heating it for a preset time, and then transporting it to the next heating zone (for a preset heating time), or transporting it to a temperature measuring zone to remeasure its temperature. Based on the heating mode of the cell, the controller obtains the corresponding transport command and the corresponding transport mode. The transport mode may include transporting the cell to a heating zone, staying there for a preset time, and then transporting it to the next heating zone (for a preset stay time), or transporting it to the temperature measuring zone.

[0086] The battery cell heat treatment control method provided in this application generates a transport command based on the temperature of the battery cell to transport the battery cell to different heating zones for heating, and achieves adaptive control of the battery cell in different states to ensure that the final temperature of the battery cell meets the production requirements.

[0087] In one embodiment, the heating zone includes a first heating zone and a second heating zone, wherein the first heating zone is used to heat the edge portion of the battery cell, and the second heating zone is used to heat the center portion of the battery cell. For example, as shown... Figure 7 As shown, the first heating zone, the second heating zone, and the temperature measuring zone are arranged sequentially, and the transport component moves sequentially between these zones. Optionally, "pallet forward once" can refer to the transport component moving the battery cell from the first heating zone to the second heating zone, or from the second heating zone to the temperature measuring zone. "pallet forward twice" can refer to the transport component moving the battery cell from the first heating zone to the temperature measuring zone. "pallet backward once" can refer to the transport component moving the battery cell from the temperature measuring zone to the second heating zone, or from the second heating zone to the first heating zone. "pallet backward twice" can refer to the transport component moving the battery cell from the temperature measuring zone to the first heating zone. It is understood that the above positional relationships and transport modes are only for illustrative purposes, and this application does not limit the specific arrangement of the first heating zone, the second heating zone, and the temperature measuring zone, or the specific transport method of the transport component.

[0088] Taking the above positional relationship as an example, based on the cell temperature, outputting a transport command to the transport component may include the following steps:

[0089] If the cell temperature meets the first preset condition, a delivery command is output; such as... Figure 8 As shown, the delivery instruction is used to instruct the delivery component to perform the following steps:

[0090] Step 802: Move the battery cell from the temperature measuring area to the second heating area.

[0091] Step 804: After the second heating component completes one heating cycle, the battery cell is moved to the first heating zone.

[0092] Step 806: After the first heating component completes one heating cycle, the battery cell is moved to the second heating zone.

[0093] Step 808: After the second heating component completes one heating cycle, the battery cell is moved to the temperature measurement area.

[0094] Specifically, the first preset condition can be that the cell temperature is within a certain temperature range. Optionally, the first preset condition can also be multiple temperature ranges, and the cell temperature can be within any of these ranges. For example, if the current cell temperature is T0, the first preset condition can be T2 > T0 > or equal to T1, or T4 > T0 > or equal to T3, or T6 > T0 > or equal to T5; where T6 > T5 > T4 > T3 > T2 > T1.

[0095] For a battery cell whose temperature meets the first preset condition, perform the following operations: retract the tray once, and control the predetermined module (i.e., the heating component of the second heating zone) to heat once according to a predetermined cycle; retract the tray again once, and control the predetermined module (i.e., the heating component of the first heating zone) to heat once according to a predetermined cycle; advance the tray once, and control the predetermined module (i.e., the heating component of the second heating zone) to heat once according to a predetermined cycle; move the tray with the battery cell to the temperature measuring area and detect the battery cell temperature T0.

[0096] In one embodiment, based on the cell temperature, a transport command is output to the transport component, and the method further includes:

[0097] If the cell temperature meets the second preset condition, a delivery command is output; such as... Figure 9 As shown, the delivery instruction is used to instruct the delivery component to perform the following steps:

[0098] Step 902: Move the battery cell from the temperature measuring area to the first heating area;

[0099] Step 904: After the first heating component completes one heating cycle, the battery cell is moved to the second heating zone;

[0100] Step 906: After the second heating component completes one heating cycle, the battery cell is moved to the temperature measurement area.

[0101] Specifically, the second preset condition can be that the cell temperature is within a certain temperature range. Optionally, the second preset condition can also be multiple temperature ranges, and the cell temperature can be within any of these ranges. For example, if the current cell temperature is T0, the second preset condition can be T3 > T0 > or equal to T2, or T5 > T0 > or equal to T4, or T7 > T0 > or equal to T6; where T7 > T6 > T5 > T4 > T3 > T2.

[0102] For a battery cell whose temperature meets the second preset condition, perform the following operations: retract the tray twice and control the predetermined module (i.e., the heating component of the first heating zone) to heat once according to a predetermined cycle; advance the tray once and control the predetermined module (i.e., the heating component of the second heating zone) to heat once according to a predetermined cycle; move the tray with the battery cell to the temperature measuring area and detect the battery cell temperature T0.

[0103] In one embodiment, based on the cell temperature, a transport command is output to the transport component, and the method further includes:

[0104] If the cell temperature meets the third preset condition, a delivery command will be output; such as... Figure 10 As shown, the delivery instruction is used to instruct the delivery component to perform the following steps:

[0105] Step 1002: Move the battery cell from the temperature measuring area to the second heating area;

[0106] Step 1004: After the second heating component completes one heating cycle, the battery cell is moved to the temperature measurement area.

[0107] Specifically, the third preset condition can be that the cell temperature is within a certain temperature range. Optionally, the first preset condition can also be multiple temperature ranges, and the cell temperature can be within any of these ranges. For example, if the current cell temperature is T0, the third preset condition can be that T8 is greater than T0 and greater than or equal to T7; where T8 is greater than T7. Further, T8 can be the target heating temperature of the cell; when the cell reaches this target heating temperature, it indicates that the cell has been fully heated.

[0108] For a battery cell whose temperature meets the third preset condition, perform the following operations: retract the tray once, control the predetermined module (i.e., the heating component of the second heating zone) to heat once according to the predetermined cycle; move the tray with the battery cell to the temperature measuring zone and detect the battery cell temperature T0.

[0109] In one embodiment, based on the cell temperature, a transport command is output to the transport component, and the method further includes:

[0110] When the cell temperature meets the cell feeding conditions, a delivery command is output;

[0111] The shipping instruction is used to instruct the shipping components to unload the battery cells.

[0112] Specifically, the cell unloading condition can be that the cell temperature meets a preset target heating temperature. For example, if the current cell temperature is T0, the cell unloading condition can be T9 greater than T0 and greater than or equal to T8; where T9 is greater than T8. Further, T9 can be the cell over-temperature protection temperature, and T8 can be the cell's target heating temperature. When the cell temperature meets the cell unloading condition, a transport command is output, instructing the transport component to unload the cell.

[0113] Optionally, when T0 is greater than T9, that is, when the current cell temperature is greater than the cell over-temperature protection temperature, or when there is a fault in the temperature sensing component, the controller can also output an alarm command to indicate a machine malfunction.

[0114] The cell heat treatment control method provided in this application embodiment performs different heating modes on cells at different temperatures to ensure that the temperature of the final unloaded cells reaches the target heating temperature.

[0115] To further illustrate the solutions of the embodiments of this application, a specific example is provided below. For example... Figure 11 As shown, when the cell heat treatment equipment enters the heat preservation mode, the feeding module stops working, meaning it no longer feeds new cells into the heat treatment equipment for heating; it only heat-treats the cells already in the equipment. For example, the cell heat treatment equipment can provide a heat preservation solution for a progressive cell heating device (also called a progressive heating device). This progressive cell heating device can include multiple heating modules, each heating module heating the cells to a different target temperature, with the target temperature of each module increasing along the direction of cell movement. In the progressive heating device, each stage of the cell has a different temperature. To ensure that the cell temperature of the final output device meets the requirements, different control schemes are used for cells in different temperature ranges. The modules (heating zones) mentioned in this application embodiment can exist in various forms, such as:

[0116] 1. It exists independently as a heat preservation device, containing two heating zones and a temperature measuring zone to keep the battery cell warm.

[0117] 2. The last two heating stages of the progressive cell heating device are designated as the first heating zone and the second heating zone.

[0118] Specifically, taking a progressive cell heating device comprising eight heating modules as an example, the target heating temperatures corresponding to each heating module are sequentially increasing: T1, T2, T3, T4, T5, T6, T7, and T8. T1 to T8 are all preset values ​​determined based on the specific parameters and manufacturing process of the cell to be heated. T8 is the target heating temperature of the progressive cell heating device, also known as the feeding temperature. It can be understood that T8 is also the target heating temperature, i.e., the feeding temperature, of a cell heat treatment device provided in this embodiment. Furthermore, it also includes a preset over-temperature protection temperature T9, which can be a preset value determined based on the specific parameters and manufacturing process of the cell to be heated.

[0119] For example, the battery cell heat treatment equipment provided in this application uses the last two stages of the progressive battery cell heating device as the first heating zone and the second heating zone. That is, the last two stages of the progressive battery cell heating device (named as the 7th dual module and the 8th single module, respectively) are used as the first heating zone and the second heating zone to heat the battery cell. The heating components of the first heating zone and the second heating zone can also be referred to as predetermined modules.

[0120] The final surface temperature of the battery cell can be collected through the temperature measuring components in the temperature measuring zone, that is, the current temperature T0 (detected value) of the battery cell when it is in the temperature measuring zone.

[0121] After the controller obtains the cell temperature T0, it determines the heat treatment method for the cell and the corresponding transportation method based on the relationship between T0 and T1 to T9.

[0122] Specifically, when T2 is greater than T0 and greater than or equal to T1, or T4 is greater than T0 and greater than or equal to T3, or T6 is greater than T0 and greater than or equal to T5, the following operations are performed on the battery cell: the tray retracts once, and the predetermined module (i.e., the heating component of the second heating zone) is controlled to heat once according to a predetermined cycle; the tray retracts again, and the predetermined module (i.e., the heating component of the first heating zone) is controlled to heat once according to a predetermined cycle; the tray moves forward once, and the predetermined module (i.e., the heating component of the second heating zone) is controlled to heat once according to a predetermined cycle; the tray with the battery cell is moved to the temperature measuring area, and the battery cell temperature T0 is detected.

[0123] When T3 is greater than T0 and greater than or equal to T2, or T5 is greater than T0 and greater than or equal to T4, or T7 is greater than T0 and greater than or equal to T6, the following operations are performed on the battery cell: the tray retracts twice, controlling the predetermined module (i.e., the heating component of the first heating zone) to heat once according to a predetermined cycle; the tray moves forward once, controlling the predetermined module (i.e., the heating component of the second heating zone) to heat once according to a predetermined cycle; the tray with the battery cell is moved to the temperature measuring area, and the battery cell temperature T0 is detected.

[0124] When T8 is greater than T0 and greater than or equal to T7, perform the following operations on the battery cell: retract the tray once, control the predetermined module (i.e., the heating component of the second heating zone) to heat once according to the predetermined cycle; move the tray with the battery cell to the temperature measuring zone and detect the battery cell temperature T0.

[0125] When T9 is greater than T0 and greater than or equal to T8, perform the following operations on the battery cell: unload the battery cell. Also, if all battery cells have been unloaded, exit the insulation mode.

[0126] In addition, when T0 is greater than T9, that is, when the current cell temperature is greater than the cell over-temperature protection temperature, or when the temperature measuring component (which can be an infrared detection instrument) is faulty, the controller can also output an alarm command to indicate the machine malfunction.
