[0040] As mentioned in the background, in related technologies, the temperature of the electrode on the surface of the battery module is generally collected through nickel sheets to reflect the temperature of the entire battery module, or the temperature of the battery body is collected by fixing the temperature sensor on a blister tray or injection molding tray. However, the collected electrode temperature may differ greatly from the actual temperature of the battery module, and the blister tray is weak, causing the temperature sensor to easily jump. The injection molding tray is too expensive and requires re-molding for batteries of different sizes, resulting in poor applicability, which leads to the problem of being unable to stably collect the temperature of the battery module.

[0041] In response to the above technical problems, an embodiment of the present application provides an integrated cover plate and a battery module, which includes a blister tray, a fixing component and a temperature collection component. The blister tray is provided with a limiting groove, and the limiting groove is provided with a first through hole. The limiting groove can ensure that the fixing component remains in a stable position to reduce movement and vibration. The fixing component is provided with a second through hole, and the thickness of the fixing component is greater than the thickness of the blister tray, thereby increasing the overall thickness and compensating for the problem of insufficient strength of the blister tray. The temperature collection component is passed through the fixing component through the first through hole and the second through hole, and is connected to the battery cell module through the first through hole and the second through hole. Therefore, the temperature of the battery cell module can be directly measured to prevent inaccurate temperature collection, thereby improving the stability and reliability of temperature measurement.

[0042] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments 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 making creative work are within the scope of protection of this application.

[0043] See Figures 1 to 4 , Figure 1 This is a schematic structural diagram of the integrated cover plate in an embodiment of the present application; Figure 2 This is a schematic diagram of the connection structure between the blister tray and the fixing assembly in an embodiment of the present application; Figure 3 This is a schematic diagram of the connection structure between the fixing component and the temperature acquisition component in the embodiment of the present application; Figure 4This is a schematic diagram of the structure of the temperature acquisition component in an embodiment of the present application.

[0044] In the first aspect, the embodiment of the present application provides an integrated cover plate, please refer to Figure 1 and Figure 3 , including: a blister tray 100, a fixing assembly 200, and a temperature collection assembly 300. The blister tray 100 is made of polycarbonate (PC), which is generally 0.5 mm thick and weak in strength. The fixing assembly 200, as an auxiliary component of the blister tray 100, can be made of a combination of polycarbonate and ABS plastic (Acrylonitrile Butadiene Styrene plastic), thereby having high impact resistance and hardness, as well as good heat resistance, cold resistance, oil resistance, and good processing performance. At the same time, the thickness of the fixing assembly 200 is greater than that of the blister tray 100, which can increase the overall thickness and improve the overall strength. At the same time, the fixing assembly 200 is used to fix the temperature collection assembly 300, which can prevent the temperature collection assembly 300 from jumping due to the blister tray 100 being too thin, and ensure that the fixing assembly 200 can provide sufficient support and fixation when the temperature collection assembly 300 is installed.

[0045] In this embodiment, the blister tray 100 is provided with a retaining groove 101. There is at least one retaining groove 101, which is not limited in this embodiment. The size and shape of the retaining groove 101 can be designed according to actual needs to accommodate different sizes of fixing assemblies 200 and different types of battery modules 400. A first through hole 102 is provided within the retaining groove 101. The size of the first through hole 102 is slightly larger than the size of the temperature collection assembly 300 to facilitate the insertion of the temperature collection assembly 300. Exemplarily, the size of the limiting groove 101 matches the size of the fixing component 200, so that the fixing component 200 can be embedded in the limiting groove 101 and fixedly connected to the blister tray 100, wherein the fixing component 200 and the blister tray 100 can be fixedly connected by other fixing methods such as hot riveting, adhesive backing, or screws. Furthermore, a second through hole 201 is provided on the fixing component 200, and the position of the second through hole 201 is aligned with the first through hole 102 in the limiting groove 101 to facilitate the setting of the temperature collection component 300.

[0046] As an example, the temperature acquisition component 300 may include a temperature sensor and a connecting wire. The temperature sensor is installed on the fixing component 200 through the first through hole 102 and the second through hole 201, and is connected to the battery cell module 400 through the connecting wire. The temperature sensor can monitor the temperature of the battery cell module 400 in real time and transmit the temperature data to an external monitoring system to realize temperature monitoring and management of the battery cell module 400.

[0047] As another example, the temperature acquisition component 300 may include multiple temperature sensors, each of which is disposed on the fixing component 200 through an independent first through-hole 102 and second through-hole 201 and connected to different locations of the battery module 400. This allows for multi-point temperature monitoring at different locations of the battery module 400, thereby improving the accuracy and reliability of temperature monitoring.

[0048] Furthermore, to further enhance the ease of installation and maintenance of the temperature acquisition assembly 300, multiple mounting holes can be provided on the fixing assembly 200, into which the temperature sensor can be fixed using screws or other fixing means. This allows for easy and convenient replacement or maintenance of the temperature sensor by simply removing the corresponding screws.

[0049] The integrated cover provided in the embodiment of the present application is provided with a limiting groove on the blister tray, a first through hole in the limiting groove, and an additional fixing component. The fixing component is provided with a second through hole and has a large thickness. The overall structure is simple and easy to install. Therefore, the fixing component is embedded in the limiting groove, which can increase the overall thickness, solve the problem of weak strength of the blister tray, and can effectively improve the safety and reliability of the battery module. The temperature acquisition device is further provided on the fixing component through the first through hole and the second through hole, which can ensure that the temperature acquisition device remains in a stable position and is not easy to slip. At the same time, the temperature acquisition component can directly monitor the temperature of the battery module through the first through hole and the second through hole, thereby improving the accuracy and stability of temperature detection, and having good scalability and convenient maintenance.

[0050] Please refer to Figure 1 and Figure 2 In one possible embodiment, the temperature acquisition component 300 includes: a temperature detection component and a heat conducting device 306. The temperature detection component can be a thermocouple, a thermistor, or other suitable temperature sensors. The temperature detection component is arranged on the heat conducting device 306. The heat conducting device 306 is connected to the battery cell module 400. The temperature information of the battery cell module 400 can be quickly obtained through the heat conducting device 306. The size of the contact surface between the heat conducting device 306 and the battery cell module 400 is smaller than the size of the first through hole 102, which facilitates the installation and removal of the heat conducting device 306 and facilitates maintenance.

[0051] Illustratively, the heat-conducting device 306 can be made of a high thermal conductivity material, such as copper or aluminum, which has good thermal conductivity and compressibility to ensure that the temperature can be quickly transferred to the temperature detection element. Furthermore, the heat-conducting device 306 can also be a thermally conductive silicone, which has an interference fit with the battery cell, adapts to the height difference of the battery cell, and further improves the thermal conductivity efficiency.

[0052] The contact surface between the heat conducting device 306 and the battery cell module 400 is small, which can ensure that the heat conducting device 306 can quickly respond to the temperature change of the battery cell module 400 while reducing physical interference with the battery cell module 400 .

[0053] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the temperature acquisition assembly 300 further includes a circuit board 302 and a reinforcement plate. The circuit board 302 may be a flexible printed circuit (FPC), a type of flexible circuit board that enables circuit connections to the battery module 400 and saves space. The reinforcement plate may be made of a high-strength material, such as stainless steel or carbon fiber, to enhance the stability and reliability of the entire temperature acquisition assembly and prevent deformation of the circuit board 302 due to mechanical stress during operation.

[0054] Furthermore, the reinforcing plate may include an upper reinforcing plate 301 and a lower reinforcing plate 303, which are respectively arranged on both sides of the circuit board 302 to provide additional support for enhancing the mechanical strength of the circuit board 302 and preventing it from being damaged due to bending or stretching during installation and use.

[0055] The reinforcing plate and circuit board 302 are stacked on the heat conducting device 306, and the temperature detection element is electrically connected to the circuit board 302. With this arrangement, when the heat conducting device 306 transfers the heat of the battery cell module 400 to the temperature collection element to obtain the temperature information of the battery cell module 400, the heat is transferred sequentially through the lower reinforcing plate 303, the circuit board 302, and the upper reinforcing plate 301. The circuit board 302 can also integrate functional modules such as signal processing circuits and data transmission modules to process and transmit the temperature data collected by the temperature detection element, thereby accurately obtaining the temperature information of the battery cell module 400 and facilitating temperature monitoring and management of the battery cell module 400.

[0056] Because circuit board 302 may contain heat-generating components, such as processors and power modules, placing circuit board 302 on mounting assembly 200 facilitates heat management and promotes the natural dissipation of heat. In some embodiments, this also facilitates the installation of heat dissipation devices such as heat sinks or cooling fans. Furthermore, technicians can more easily disassemble and inspect circuit board 302, reducing maintenance time and complexity and improving the maintainability of the energy storage system.

[0057] It should be noted that the upper reinforcing plate 301 and the circuit board 302, the circuit board 302 and the lower reinforcing plate 303, and the lower reinforcing plate 303 and the heat conducting device 306 can be bonded with adhesive to prevent the overall structure of the temperature acquisition component 300 from separating or loosening.

[0058] Please refer to Figure 1 、 Figure 2 as well as Figure 3 In this embodiment, a third through-hole 304 is provided on the reinforcement plate, and a fixing member 202 is provided on the fixing assembly 200 for fixing the temperature acquisition assembly 300. The fixing member 202 may be a screw, rivet, or other suitable fixing device. For example, the fixing member 202 may be a thermal rivet stud. The position of the thermal rivet stud can be adjusted to meet the different requirements of the width of the circuit board 302 and the resulting position of the temperature acquisition assembly 300. The thermal rivet stud fixing method can effectively reduce stress concentration, prevent component damage caused by mechanical stress, and improve the reliability of the energy storage system. This configuration enables the fixing assembly 200 to accommodate circuit boards 302 of various specifications and sizes, improving the flexibility and adaptability of the fixing assembly 200.

[0059] The fixing member 202 is passed through the third through hole 304, and can fix the temperature acquisition component 300 to the fixing component 200, so that the temperature acquisition component 300 is located in the second through hole 201 on the fixing component 200, and can be heated evenly to avoid local overheating, which is helpful for the thermal management of the energy storage system.

[0060] In this embodiment, a temperature-sensitive glue hole 305 is provided on the reinforcement plate. The shape of the temperature-sensitive glue hole 305 can be adjusted according to the shape of the temperature detection component to adapt to different types of temperature detection components. When the number of third through holes 304 is two, the position of the temperature-sensitive glue hole 305 can be located between the two third through holes 304 to ensure the stability of the temperature detection component.

[0061] The temperature sensing glue hole 305 is used to fix the temperature detection component to the reinforcement plate. By glue fixation, the temperature detection component can be maintained in the predetermined position, ensuring close contact between the temperature detection component and the reinforcement plate, and conducting heat, thereby improving the reliability and stability of the energy storage system. On the one hand, it can ensure that the heat of the battery module 400 conducted by the heat conduction device 306 is effectively conducted to the temperature detection component, ensuring that the temperature detection component can collect temperature information of the battery module 400 and improve the heat conduction efficiency. On the other hand, it can reduce the thermal resistance between the temperature detection component and the battery module 400, ensuring that the temperature detection component can quickly and accurately respond to temperature changes, thereby improving the accuracy of temperature monitoring.

[0062] The dispensing material may be thermally conductive adhesive or thermally conductive silicone grease, which can fill the gap between the temperature detection component and the reinforcement plate to ensure good thermal contact.

[0063] The integrated cover provided in the embodiment of the present application can enhance the mechanical strength and stability of the entire temperature acquisition component by optimizing the temperature acquisition component and adding a heat-conducting device, a circuit board, and a reinforcement plate, thereby ensuring that the temperature can be quickly transmitted to the temperature detection component and processing and transmitting the temperature data collected by the temperature detection component in real time. In addition, by providing a third through hole and a temperature-sensing glue hole on the reinforcement plate, the temperature acquisition component can be fixed to ensure that it will not be displaced or loosened due to vibration or other external forces during operation, so that it can quickly and accurately obtain the temperature information of the battery cell module.

[0064] Please continue to refer to Figure 1 、 Figure 2 as well as Figure 3 In one possible embodiment, both ends of the fixing assembly 200 are in a stepped structure, and the stepped structure is recessed from the middle position of the fixing assembly 200 from top to bottom in the length direction of the fixing assembly 200. The stepped design can disperse and evenly distribute the externally applied mechanical stress, reduce stress concentration, and thus improve the deformation resistance and stability of the fixing assembly 200. At the same time, the stepped structure can provide multiple positioning surfaces and support surfaces, so that the fixing assembly 200 can be more accurately aligned and fixed during the installation process, thereby ensuring that the temperature acquisition assembly 300 and other related components are accurately positioned during installation, reducing installation errors, and improving the overall accuracy of the energy storage system.

[0065] In this embodiment, the blister tray 100 is covered above the battery cell module 400, the fixing component 200 is located in the limiting groove 101 in the blister tray 100, and the circuit board 302 is covered on the fixing component 200. The multiple components are closely connected, and the steps of different heights can provide support and fixed positions for components of different thicknesses and different positions, thereby realizing the close integration of multi-layer components and the modular design of the energy storage system.

[0066] The stepped structure is symmetrically provided with fourth through holes 203 for avoiding the thermal rivet studs on the pole piece 401 , reducing the complexity and interference of the wiring of the circuit board 302 , and preventing the temperature acquisition component 300 from affecting the temperature monitoring of the battery module 400 .

[0067] The integrated cover provided in the embodiment of the present application can effectively enhance the structural strength and stability of the energy storage system through the stepped structure design at both ends of the fixing component, so that the fixing component can be more accurately aligned and fixed during the installation process, thereby improving the overall accuracy of the energy storage system.

[0068] Please refer to Figure 1 and Figure 4In one possible embodiment, at least one protrusion 103 is provided within the limiting groove 101 of the blister tray 100, and the height of the protrusion 103 is the same as that of the non-limiting groove portion of the blister tray 100. The protrusion 103 is inserted into the second through hole 201 to further enhance the stability and positioning accuracy between the fixing assembly 200 and the blister tray 100.

[0069] The protrusion 103 may be in a cylindrical, square column or other suitable shape so as to be passed through the second through hole 201 of the fixing assembly 200 , thereby enabling the fixing assembly 200 to be accurately positioned during installation on the blister tray 100 to avoid displacement and loosening.

[0070] Please continue to refer to Figure 1 and Figure 4 In one possible embodiment, pole piece fixing holes 104 are symmetrically provided at both ends of the blister tray 100. The blister tray 100 provides a unified base, which facilitates the quick and accurate assembly of multiple battery cells and pole pieces 401, thereby improving work efficiency. The symmetrical arrangement of the pole piece fixing holes 104 at both ends of the blister tray 100 helps to evenly distribute the heat generated by the battery module 400 during operation, prevent local overheating, and reduce the impact of thermal stress on battery materials, thereby extending the service life of the battery. The pole piece 401 of the battery module 400 is fixedly connected to the blister tray 100 through the pole piece fixing holes 104. The pole piece 401 is the electrode of the battery module 400 and is used to conduct current. The pole piece 401 can be fixed in the pole piece fixing hole 104 by welding, screwing, or other suitable methods, thereby simplifying the assembly process of the battery module 400. As a result, it can be ensured that the battery module 400 will not be displaced or loosened due to vibration or other external forces during operation, thereby improving the stability and safety of the energy storage system.

[0071] Please refer to Figure 1 、 Figure 2 as well as Figure 4 In this embodiment, the circuit board 302 is electrically connected to the electrode 401, wherein the electrode 401 is the electrode of the battery, responsible for the input and output of current. Through the circuit board 302, the current of the electrode 401 can be conducted to other circuits or devices to realize the transmission and utilization of electric energy.

[0072] The integrated cover provided in the embodiment of the present application, through the protrusion design on the blister tray, enables the fixing component to be accurately positioned during the installation process to avoid displacement and loosening. The pole piece fixing holes designed symmetrically at both ends of the blister tray can fix the pole piece to the blister tray, ensuring that the battery cell module will not be displaced or loosened due to vibration or other external forces during operation, thereby improving the stability and safety of the energy storage system. At the same time, the circuit board is electrically connected to the pole piece, which can transmit and utilize electrical energy and realize the basic functions of the battery.

[0073] Secondly, embodiments of the present application provide a battery module comprising the integrated cover according to the first aspect and any possible implementation. The fixing assembly 200 enhances the strength of the blister tray 100, ensuring that the temperature acquisition assembly 300 does not shift or loosen due to vibration or other external forces during operation, thereby improving the reliability of the energy storage system. Furthermore, the temperature acquisition assembly 300 monitors the temperature of the battery module in real time, enabling timely detection and prevention of overheating, thereby avoiding battery failure or safety incidents caused by overheating.

[0074] The battery module provided in the embodiment of the present application makes the installation and maintenance of the battery module easier through the modular design of the integrated cover plate, and the connection and fixing methods between the various components are easy to implement, which reduces maintenance time and complexity, improves assembly efficiency, and thus improves the maintainability of the energy storage system.
