[0002] A battery module typically contains or includes multiple batteries. Multiple batteries can be connected in series or parallel via a busbar or other structures to deliver electrical energy. To effectively monitor the battery temperature, a temperature sensing unit can be provided in the battery module. Typically, the temperature sensing unit indirectly detects the battery temperature based on the battery heat transferred via the busbar or other structures. Because the battery heat is affected by the busbar or other structures, the temperature detected by the temperature sensing unit may not accurately reflect the battery temperature. SUMMARY

Unless otherwise defined or described, the terms "connect" and "fix" should be interpreted broadly; for example, the term "connect" can mean "firmly connect," "removably connect," "integrally connect," "electrically connect," or "signal." The term "connect" can also mean "directly connect" or "indirectly connect via a medium."

[0011] In describing the present disclosure, it should be noted that spatially relative terms such as "top," "bottom," "inside," "outside," and the like are described based on the orientations depicted in the figures, but are not intended to limit the exemplary embodiments of the present disclosure.

[0012] In this context, it should also be understood that an element or features provided "outside" or "inside" another element or elements may be provided directly "outside" or "inside" the other element or elements, or may be provided indirectly "outside" or "inside" the other element or elements through an intermediate element.

[0013] In order to enable those skilled in the art to better understand the technical solutions of the disclosure, the embodiments of the disclosure will be described in detail below with reference to the accompanying drawings.

[0014] As in Fig. 1, one embodiment of the disclosure provides a battery module 10 comprising a battery 11 and a temperature sensing unit 12. Referring to Fig. 2, the temperature detection unit 12 includes a support plate 121 and a thermal element 122. The thermal element 122 is disposed on an upper surface of the support plate 121 (see the direction shown in the drawings). A lower surface of the support plate 121 is firmly attached or fixed to a casing of the battery 11. The temperature of the battery 11 can be directly transferred to the thermal element 122 via the support plate 121. Accordingly, heat transfer between the battery 11 and the thermal element 122 can be effectively reduced, so that the thermal element 122 can more accurately reflect the temperature of the battery 11.

[0015] In practical applications, the battery module 10 can be used in various fields. For example, the battery module 10 described above can be used in vehicles, ships, drones, and the like. For example, a vehicle can be equipped with the battery module 10 described above. The battery 11 in the battery module 10 can provide electrical power to a drive device (e.g., a motor) in the vehicle, and the vehicle can perform driving and other functions when the drive device is operated. In practical applications, the temperature detection unit 12 can effectively monitor the temperature of the battery 11 to ensure that the battery 11 is within an appropriate temperature range.For example, if the temperature detection unit 12 detects that the temperature of the battery 11 is relatively low, a heater in the vehicle may heat the battery 11 to improve the efficiency of the battery 11. Or, if the temperature detection unit 12 detects that the temperature of the battery 11 is relatively high, the heater in the vehicle may cool the battery 11 to improve the safety of the battery 11.

[0016] In the actual implementation, the types of thermal element 122 may be different.

[0017] The thermal element 122 is an element made of a thermosensitive material whose physical properties change with temperature changes. This type of element can be installed on a printed circuit board (PCB) or a flexible circuit board. Thermal elements are typically packaged in a form similar to metal film resistors, small ceramic capacitors, and surface-mount solder elements. In this case, they are often referred to as thermistors. The resistance of some thermistors decreases with increasing temperature, such as an NTC (Negative Temperature Coefficient) thermistor. The resistance value of the NTC thermistor can decrease with increasing temperature. Due to its large temperature coefficient, it can detect small temperature changes, so it accurately reflects the temperature value of the battery 11.For temperature sensing applied to the surface of specific objects or a specific ambient temperature, the thermal element is typically manufactured in a variety of packaging forms according to the specific application, commonly known as thermal sensors, to adapt to the sensing environment and facilitate installation. In the disclosure, the thermistor and thermal sensor are collectively referred to as an NTC thermistor. It should be understood that in some embodiments, the thermal element 122 is not limited to including only the NTC thermistor. The disclosure is not limited in this regard.

[0018] In addition, the types of carrier plate 121 can also be different in the concrete implementation.

[0019] The carrier plate 121 can be, for example, a printed circuit board. In particular, the circuit board can be a printed circuit board (PCB) or a flexible printed circuit board (FPC). The thermal element 122 can be arranged on the carrier plate 121, including, but not limited to, methods such as welding, surface mounting, or the like, and establish an electrical connection with the carrier plate 121.

[0020] Furthermore, in the specific embodiment, the battery module 10 may include a plurality of batteries 11 and the same number of temperature detection units 12 as the batteries 11. The temperature detection units 12 may be connected one-to-one to the batteries 11 to effectively monitor the temperature of each of the batteries 11. Furthermore, each of the temperature detection units 12 may be an independent structural element or a structural element with a specific integrated design. In the following description, the carrier plate 121 is, for example, the printed circuit board. As shown in Fig. 1, in one embodiment of the disclosure, a plurality of temperature sensing units 12 share a circuit board 121. Specifically, the circuit board 121 may include a main section 1211 and branch sections 1212. Each of the branch sections 1212 may be equipped with a thermal element 122. It should also be understood that a circuit board of each of the branch sections 1212 may be divided into the circuit boards of the temperature sensing units 12. This structural arrangement assists in the manufacturing and molding of the circuit board 121. Therefore, it is advantageous to improve the integrated adjustment and mass production of the temperature sensing unit 12 and reduce the manufacturing cost.

[0021] The structure of the temperature detection unit 12 is described in detail below.

[0022] As in Fig. 3 and Fig. As shown in Figure 4, the temperature sensing unit 12 in one embodiment of the disclosure includes the circuit board 121 and the thermal element 122 disposed on the circuit board 121. In order to provide a certain protective function for the thermal element 122 and prevent the thermal element 122 from being damaged by an external force, the temperature sensing unit 12 in one embodiment of the disclosure further includes a protective structure. Specifically, the protective structure may be disposed on an upper surface of the circuit board 121 and surround a periphery of the thermal element 122. When the top, left, right, front, and back sides of the circuit board 121 are impacted by foreign matter, the protective structure can effectively prevent the foreign matter from directly impacting the thermal element 122 to improve the protective performance of the thermal element 122.

[0023] In actual implementation, the types and structural forms of the protective structure may vary. In particular, the protective structure may include a rigid post 123 or a flexible post 124. That is, the protective structure may include only the rigid post 123 or only the flexible post 124. Alternatively, both the rigid post 123 and the flexible post 124 may be included.

[0024] As in Fig. 3, in one embodiment of the disclosure, the protective structure includes the rigid stator 123. In particular, the rigid stator 123 may include a lower frame 1231 and a protective claw 1232. The rigid stator 123 is fixedly connected to the circuit board 121 via the lower frame 1231. The protective claw 1232 extends upward and surrounds the thermal element 122 in a space enclosed by the lower frame 1231 and the protective claw 1232.

[0025] In concrete implementation, the rigid post 123 can be made of, but not limited to, metal, resin, polyethylene, and polypropylene materials. When the rigid post 123 is made of a metal material, in some embodiments, the rigid post 123 can be arranged on the circuit board 121 by methods such as welding, gluing, or the like. When the rigid post 123 is made of a non-metal material such as resin, the rigid post 123 can be arranged on the circuit board 121 by methods such as gluing or the like.

[0026] To improve the dustproof and waterproof properties of the thermal element 122, a sealant 120 may be attached to the periphery of the thermal element 122. Specifically, the sealant 120 may fill a gap between the thermal element 122 and the rigid post 123. This structural arrangement can also effectively improve the protection performance of the thermal element 122. For example, when the rigid post 123 is deformed by an external force, the sealant 120 can absorb a certain impact force to weaken the impact force transmitted from the rigid post 123 to the thermal element 122.

[0027] To improve the performance of the temperature sensing unit 12, in some embodiments, the sealant 120 may be made of a material with favorable thermal conductivity, such as a thermally conductive silicone, so that the heat on the circuit board 121 or the rigid post 123 can be efficiently transferred to the thermal element 122.

[0028] In some embodiments, the protective structure may further include the elastic stand 124. As shown in Fig. As shown in Figure 3, the elastic post 124 may be a "rectangular donut"-shaped structure (a rectangular structure with a rectangular hole or cavity) surrounding the periphery of the thermal element 122 (or the rigid post 123). The height of the elastic post 124 may be greater than the height of the rigid post 123. When an upper part of the circuit board 121 is struck by a foreign object, an impact force first acts on the elastic post 124. The elastic post 124 can effectively absorb the impact force through its own elastic deformation. Therefore, the impact force transmitted to the rigid post 123 can be effectively mitigated, so that bending deformation of the rigid post 123 due to excessive force is effectively avoided and ultimately the protection effect for the thermal element 122 is improved.

[0029] In some embodiments, the rigid post 123 may also be shaped like a "rectangular donut" or take on other shapes and structures. The disclosure is not limited in this regard.

[0030] As in Fig. As shown in Figure 4, in one embodiment of the disclosure, the rigid post 123 is a "rectangular donut," and the elastic post 124 is also a "rectangular donut." The elastic post 124 is stacked on top of the rigid post 123. In practice, the thickness (or height) of the rigid post 123 may be greater than the thickness (or height) of the thermal element 122, so that the rigid post 123 can provide a favorable protective effect for the thermal element 122. In actual implementation, the rigid post 123 and the elastic post 124 may be firmly connected to each other by gluing or the like, and the elastic post 124 may be made of elastic materials such as foam.

[0031] In the actual implementation, the way in which the temperature detection unit 12 and the battery 11 are connected may also be different.

[0032] For example, the temperature sensing unit 12 can be glued to the housing of the battery 11. In particular, as shown in Fig. 3 and Fig. 4, the lower surface of the circuit board 121 may be provided with an adhesive layer 125, and the circuit board 121 may be adhesively attached or bonded to the casing of the battery 11 by the adhesive layer 125.

[0033] In some embodiments, a reinforcement plate 126 may be attached to the bottom surface of the circuit board 121 to provide the circuit board 121 with favorable load-bearing capacity. In practice, the reinforcement plate 126 may be a structure molded integrally with the circuit board 121 or an additional structural component added later. Specifically, the reinforcement plate 126 may be attached directly to the bottom surface of the circuit board 121 during the manufacture of the circuit board 121. Alternatively, the reinforcement plate 126 may be a separate plate-shaped structure that may be later attached to the bottom surface of the circuit board 121 by methods such as gluing, welding, or the like.

[0034] On the other hand, when the temperature detection unit 12 and the battery 11 are fixed together, a positioning slot 111 may be provided on the housing of the battery 11 to ensure accurate positioning of the temperature detection unit 12 and the battery 11. As shown in Fig. 5 and Fig. 6, the depth of the positioning slot 111 may, in practice, be greater than the height of the temperature sensing unit 12. Alternatively, the depth of the positioning slot 111 may also be equal to or less than the height of the temperature sensing unit 12. In particular, an upper surface of the temperature sensing unit 12 (or the protective structure) may be lower than a surface of the positioning slot 111. Alternatively, the upper surface of the temperature sensing unit 12 (or the protective structure) may be aligned with the surface of the positioning slot 111, or the upper surface of the temperature sensing unit 12 (or the protective structure) may be higher than the surface of the positioning slot 111.With the above structural arrangement, not only can the positioning accuracy for the temperature detection unit 12 and the battery 11 be ensured, but also advantages such as improved space utilization of the battery module 10 and reduced space occupation of the battery module 10 can be achieved.

[0035] Furthermore, in some embodiments, the temperature sensing unit 12 and the battery 11 may also be mounted in other forms relative to or fixed relative to each other.

[0036] In one embodiment of the disclosure, the battery module 10 includes, for example, a wiring harness plate component (not shown in the drawings). The wiring harness plate component may be fixedly connected to the battery. A lower side of the wiring harness plate component may abut against an upper part of the protective structure (an upper part in the drawing). In the specific embodiment, the wiring harness plate component may include a wiring harness plate 13. The wiring harness plate 13 may perform a type of support or protective function for cables and other components in the battery module 10. Furthermore, in some embodiments, the wiring harness plate 13 may also provide relative fixation between the temperature sensing unit 12 and the battery 11.Specifically, a lower surface of the wire harness plate 13 may abut against an upper surface of the elastic stand 124 in the temperature detecting unit 12 to press the temperature detecting unit 12 into a space between the wire harness plate 13 and the battery 11.

[0037] In practice, the temperature sensing unit 12 may rely only on the pressing force of the wiring harness plate 13 to ensure the relative position with the battery 11, or it may be combined with the above-described connecting layer 125 to improve the stability of the relative position between the temperature sensing unit 12 and the battery 11, thus preventing the relative position between the temperature sensing unit 12 and the battery 11 from being changed. Specifically, the temperature sensing unit 12 may be firmly connected to the battery 11 through the connecting layer 125, or a more stable connection may be established between the temperature sensing unit 12 and the battery 11 through the pressing force of the wiring harness plate 13 to prevent the relative position between the temperature sensing unit 12 and the battery 11 from being changed due to external vibrations or collisions.

[0038] To ensure that the temperature sensing unit 12 is effectively pressed onto the battery 11 by the wiring harness plate 13, the elastic stand 124 in the temperature sensing unit 12 may protrude slightly from the positioning slot 111 in the casing of the battery 11; or the upper surface of the temperature sensing unit 12 (or the protective structure) may be higher than the surface of the positioning slot 111.

[0039] In addition, in practice, the positional relationship between the circuit board 121 and the wiring harness board 13 may also be different.

[0040] For example, the entire circuit board 121 may be entirely housed in the space between the wiring harness plate 13 and the battery 11. Alternatively, the main portion 1211 of the circuit board 121 may be located on top of the wiring harness plate 13, and the branch portion 1212 (or the temperature sensing unit 12) of the circuit board 121 may be located in the space between the wiring harness plate 13 and the battery 11.

[0041] As in Fig. 1 and Fig.6, in one embodiment of the disclosure, the main portion 1211 of the circuit board 121 is located on the top surface of the wiring harness plate 13, and the branch portion 1212 (or the temperature sensing unit 12) of the circuit board 121 is located in the space between the wiring harness plate 13 and the battery 11. Specifically, a receiving slot 131 for receiving the temperature sensing unit 12 is provided on a lower side of the wiring harness plate 13. A side wall of the receiving slot 131 is provided with a cable passage 132. The branch portion in the circuit board 121 can protrude from the cable passage 132 into the receiving slot 131, thus facilitating assembly.

[0042] When assembling the battery module 10, a bus bar (not shown in the drawing, the bus bar may be a conductive plate-like structure such as an aluminum plate) and the battery 11 may be mounted first. Specifically, a plurality of batteries 11 may be arranged in predetermined positions. Subsequently, the bus bar may be mounted over the batteries 11, and the bus bar and a terminal 112 of the battery 11 may be connected by methods such as welding or the like, thereby establishing electrical and mechanical connections between the bus bar and the batteries 11. Then, the wire harness plate 13 and the circuit board 121 may be assembled. Specifically, the main portion 1211 of the circuit board 121 may be first mounted on top of the wire harness plate 13.Subsequently, the branch portions 1212 (or the temperature sensing unit 12) of the circuit board 121 can be inserted into the receiving slot 131 of the wiring harness board 13, so that the wiring harness board 13 and the circuit board 121 can be joined together. Then, the wiring harness board 13, the circuit board 121, and the batteries 11 can be assembled. Specifically, a component consisting of the wiring harness board 13 and the circuit board 121 can be placed over the batteries 11. Next, the wiring harness board 13 is pressed down so that a lower surface of the branch portion 1212 of the circuit board 121 is fixed to the housing (or the positioning slot 111) of the battery 11. Subsequently, the wiring harness board 13 and the batteries 11 can be firmly connected to each other using adhesives, screws, or other fasteners, thereby achieving the assembly process for integrating the battery module 10.

[0043] Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the disclosure. These variations, uses, or adaptations follow the general principles of the disclosure and incorporate common knowledge or conventional technical means not disclosed in the present disclosure.
