In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] like Figure 1 As shown, this embodiment proposes a battery, which includes a battery module and a temperature acquisition component. The battery module includes a plurality of battery cells 10 arranged side by side. The temperature acquisition component is used to collect the temperature of the battery cells 10 and transmit the collected temperature to a battery management system to accurately monitor the real-time temperature of the battery cells 10.

[0041] Specifically, the battery of this embodiment is a large cylindrical battery, and the battery cell 10 of the large cylindrical battery is a cylindrical battery cell. Figure 1 As shown, in order to reduce the temperature rise of the battery cell 10, liquid cooling plates 20 are installed on both sides of the battery cell 10 in the circumferential direction. The liquid cooling plates 20 are in a serpentine structure to better fit the circumferential side of the battery cell 10 and improve the cooling effect. Due to the presence of the liquid cooling plates 20, the temperature collection component is installed on the circumferential side of the cylindrical battery cell and is located between two adjacent liquid cooling plates 20 to minimize the impact of the liquid cooling plates 20 on the collected temperature.

[0042] Due to the presence of the liquid cooling plate 20, the installation space on the battery cell 10 is limited. The temperature measuring element of the existing temperature collection assembly is generally installed on the upper surface of the negative electrode of the battery cell 10 or on the temperature measuring frame of the temperature collection assembly by bonding with thermal conductive adhesive to collect the temperature of the battery cell 10 in real time. The existing temperature collection assembly has the problem that the temperature measuring element installed by bonding is easy to loosen or fall off, and the temperature measuring element also has the problems of cumbersome disassembly and assembly operation, and inconvenient replacement and maintenance.

[0043] To solve the above problems, Figure 2 and Figure 3 As shown, this embodiment also proposes a temperature acquisition component, which includes a measuring frame 1, a tooling plate 2, a temperature measuring component 3 and an electrical connector 4. The measuring frame 1 can be snap-fitted and installed on the circumferential side of the battery cell 10. The tooling plate 2 can be detachably installed on the measuring frame 1. The temperature measuring component 3 is installed on the tooling plate 2 to measure the temperature of the battery cell 10. One end of the electrical connector 4 is electrically connected to the temperature measuring component 3, and the temperature measuring component 3 is communicated with the battery management system through the electrical connector 4. By installing the temperature measuring component 3 on the tooling plate 2, it is possible to prevent the temperature measuring component 3 from loosening and falling off, thereby achieving a stable installation of the temperature measuring component 3 and improving the protection of the temperature measuring component 3. At the same time, the tooling plate 2 and the measuring frame 1 are assembled in a detachable manner, so that the tooling plate 2 and the temperature measuring component 3 can be quickly disassembled and assembled on the measuring frame 1, which is convenient for maintenance and replacement of the temperature measuring component 3 and improves the disassembly and assembly efficiency of the temperature measuring component 3. Specifically, the measuring frame 1 is provided with a mounting groove 110, and the tooling plate 2 is plugged and installed in the mounting groove 110. The tooling plate 2 is provided with a receiving hole 21, and the temperature measuring element 3 is installed in the receiving hole 21. By installing the temperature measuring element 3 in the receiving hole 21 of the tooling plate 2, it is possible to prevent the temperature measuring element 3 from loosening and falling off. At the same time, the tooling plate 2 is plugged into the mounting groove 110 of the measuring frame 1, so that the tooling plate 2 and the temperature measuring element 3 can be quickly plugged in and installed.

[0044] like Figure 3 and Figure 4As shown, a sealant 7 is provided in the receiving hole 21, and the temperature measuring element 3 is located in the receiving hole 21 and wrapped in the sealant 7. By pouring the sealant 7 in the receiving hole 21 to wrap the temperature measuring element 3, not only a good limiting effect is provided on the temperature measuring element 3, but also the water vapor protection ability of the temperature measuring element 3 is improved. The sealant 7 of this embodiment can be a photosensitive adhesive, which has the advantages of fast curing, high strength, good transparency, etc. In other embodiments, the sealant 7 can also be other colloids, which are not specifically limited here.

[0045] It should be noted that the electrical connector 4 of this embodiment is an FPC flexible row. Since the FPC flexible row is relatively thin, easy to bend and not easily damaged, it can stably transmit the temperature of the battery cell 10 collected by the temperature measuring component 3 to the battery management system. The temperature measuring component 3 of this embodiment is a thermistor, which has the advantages of high measurement accuracy, small size, and easy disassembly and maintenance. Of course, the temperature measuring component 3 can also be other temperature measuring components such as temperature sensors, which are not specifically limited here.

[0046] like Figure 2 and Figure 3 As shown, the electrical connector 4 includes a first connecting portion 41 and a second connecting portion 42 connected by bending, the first connecting portion 41 extends along the axial direction of the battery cell 10, the first connecting portion 41 is electrically connected to the temperature measuring component 3, the first connecting portion 41 and the second connecting portion 42 are connected at an angle, and the second connecting portion 42 is connected to the battery management system for communication. The electrical connector 4 is a bent structure, which reduces the length of the electrical connector 4 along the axial direction of the battery cell 10, thereby reducing the space occupied by the electrical connector 4 along the axial direction of the battery cell 10, avoiding interference between the electrical connector 4 and the CCS assembly at the top of the battery cell 10, and realizing reliable installation of the electrical connector 4.

[0047] Furthermore, the second connecting portion 42 (the other end away from the temperature measuring component 3) is electrically connected to a connector 8. The connector 8 is used to plug and unplug the external connector to achieve communication connection between the electrical connector 4 and the battery management system, thereby improving the wiring efficiency and stability of the electrical connector 4. Since the electrical connector 4 (FPC soft row) is easy to bend, a second reinforcement plate 9 is also installed at one end of the electrical connector 4 where the connector 8 is installed, and the second reinforcement plate 9 and the connector 8 are respectively located on opposite sides of the electrical connector 4. By providing the second reinforcement plate 9, the structural strength of the end of the second connecting portion 42 where the connector 8 is installed is enhanced, thereby improving the connection stability between the electrical connector 4 and the connector 8. Since the electrical connector 4 and the connector 8 are connected by welding, the second reinforcement plate 9 can provide support for the electrical connector 4, and the welding equipment positions the electrical connector 4 by clamping and fixing the second reinforcement plate 9, thereby improving the welding quality and welding efficiency between the electrical connector 4 and the connector 8.

[0048] like Figure 5As shown, the measuring frame 1 includes a base 11 and an arm plate 12, and the tooling plate 2 is detachably mounted on the base 11. The arm plate 12 extends outward from at least one side of the base 11, and the base 11 and the arm plate 12 form a card slot 120 that can be snap-fitted with the battery cell 10. Specifically, the arm plates 12 extend outward from the opposite sides of the base 11, and the base 11 is provided with a mounting groove 110. The top of the mounting groove 110 has an opening, and the tooling plate 2 is installed in the mounting groove 110 through the opening or pulled out from the mounting groove 110 through the opening, so that the tooling plate 2 can be quickly disassembled and assembled.

[0049] Specifically, since the battery cell 10 is a cylindrical battery cell, the arm plate 12 includes an arc plate that elastically hugs the circumferential side of the battery cell 10. The arm plate 12 of this embodiment is a long arc plate, so that the arm plate 12 can be clamped in the narrow space between the top of the negative pole of the battery cell 10 and the top of the liquid cooling plate 20. The measuring frame 1 is installed on the circumferential side of the battery cell 10 along the radial direction of the battery cell 10, so that the battery cell 10 enters the card slot 120 from the notch, and the two arm plates 12 elastically hug the battery cell 10, so that the measuring frame 1 is firmly installed on the battery cell 10.

[0050] As a preferred solution, Figure 5 As shown, the center angle α corresponding to the notch is 120° to 160°. For example, the center angle α of the present embodiment can be 120°, 130°, 140°, 150° or 160°, etc. Setting the center angle α to the above value can ensure that the notch has sufficient spacing, which is convenient for the battery cell 10 to enter the slot 120 from the notch, while also ensuring that the two arm plates 12 hold the battery cell 10 tightly, thereby achieving reliable installation of the measuring frame 1. When the center angle α is too small, the spacing of the notch is small, and it is difficult for the battery cell 10 to enter the slot 120, which increases the difficulty of installing the measuring frame 1; when the center angle α is too large, the extension length of the arm plate 12 is small, and it is impossible to hold the battery cell 10 tightly, thereby reducing the stability of the measuring frame 1.

[0051] like Figure 5 As shown, the seat body 11 includes a bottom plate 111, a first side plate 112 and a second side plate 113, and the first side plate 112 and the second side plate 113 are respectively arranged on opposite sides of the bottom plate 111, so that the bottom plate 111, the first side plate 112 and the second side plate 113 surround the installation groove 110. The first side plate 112 has arm plates 12 extending outward on opposite sides thereof. Since the battery cell 10 is a cylindrical battery cell, the first side plate 112 is in an arc shape and is concentric with the arm plate 12, so that the first side plate 112 and the two arm plates 12 are closely fitted with the circumferential side of the battery cell 10, thereby improving the stability of the installation of the measuring frame 1, and at the same time making the temperature measuring component 3 as close to the battery cell 10 as possible, so as to improve the measurement accuracy.

[0052] It should be noted that the inner side surface of the first side plate 112 is provided with an adhesive layer 6, and the adhesive layer 6 can be bonded to the battery cell 10. When the measuring frame 1 is installed on the circumferential side surface of the battery cell 10 along the radial direction of the battery cell 10, the adhesive layer 6 is bonded to the circumferential side surface of the battery cell 10, further improving the connection strength and installation stability of the measuring frame 1 and the battery cell 10. Specifically, double-sided tape can be bonded to the side surface of the first side plate 112 to form the adhesive layer 6. Double-sided tape has good bonding strength, is easy to use and has low cost.

[0053] like Figure 4 and Figure 5 As shown, the tooling plate 2 is also provided with a positioning groove 22, and the base body 11 has a first buckle 114, and the buckle head of the first buckle 114 is engaged in the positioning groove 22. The first buckle 114 extends into the installation groove 110 and engages with the positioning groove 22 of the tooling plate 2 to lock the tooling plate 2 in the installation groove 110, thereby improving the reliable fixation of the tooling plate 2 and the temperature measuring component 3.

[0054] Specifically, a positioning groove 22 is provided on both opposite sides of the tooling plate 2, and two first buckles 114 are correspondingly provided on the bottom plate 111. When the tooling plate 2 is plugged and installed in the installation groove 110, the two first buckles 114 are respectively engaged in the corresponding positioning grooves 22, thereby improving the stability of the tooling plate 2. The second side plate 113 includes two L-shaped plates arranged opposite to each other, and the L-shaped plates enclose an escape space for installing the first buckle 114, so that the first buckle 114 and the second side plate 113 are located on the same side of the bottom plate 111, and each first buckle 114 is respectively installed in the escape space enclosed by the corresponding second side plate 113.

[0055] like Figure 5 As shown, the seat body 11 is provided with a detection port 1120 (the first side plate 112 is provided with a detection port 1120), the mounting slot 110 is connected with the card slot 120 through the detection port 1120, and one end of the electrical connector 4 extends into the detection port 1120 and is electrically connected to the temperature measuring element 3. By providing the detection port 1120, the first side plate 112 is prevented from isolating the battery cell 10 from the temperature measuring element 3, so that the temperature measuring element 3 can accurately measure the temperature of the battery cell 10.

[0056] like Figure 2 and Figure 3As shown, the inner side of the first connection part 41 is electrically connected to the temperature measuring part 3, and the outer side of the first connection part 41 facing away from the temperature measuring part 3 is provided with a first reinforcing plate 5, and the first reinforcing plate 5 can be pressed against the circumferential side of the battery core 10. Since the electrical connector 4 (FPC soft row) is easy to bend, the end of the first connection part 41 welded with the temperature measuring part 3 is also installed with the first reinforcing plate 5, and the first reinforcing plate 5 and the temperature measuring part 3 are respectively located on two opposite sides of one end of the first connection part 41. By providing the first reinforcing plate 5, the structural strength of the end of the first connection part 41 welded with the temperature measuring part 3 is improved, and the stability of the connection between the electrical connector 4 and the temperature measuring part 3 is improved. Since the electrical connector 4 and the temperature measuring part 3 are connected by welding, the first reinforcing plate 5 provides support for the electrical connector 4, so that the welding equipment can weld and position the electrical connector 4 by clamping and fixing the first reinforcing plate 5, thereby improving the welding quality and welding efficiency of the electrical connector 4 and the temperature measuring part 3.

[0057] In this embodiment, the temperature measuring component 3 is connected to the circumferential side of the battery cell 10 through the electrical connector 4 and the first reinforcement plate 5. Since the thickness of the electrical connector 4 and the first reinforcement plate 5 is relatively small, the impact on the measurement accuracy of the temperature measuring component 3 is relatively small, and basically does not affect the temperature measuring component 3 from accurately measuring the temperature of the battery cell 10.

[0058] Furthermore, if Figure 5 and Figure 6 As shown, the base 11 has a second buckle 115, and the buckle head of the second buckle 115 is pressed against the side of the tooling plate 2 away from the detection port 1120, so that the other side of the tooling plate 2 close to the detection port 1120 is pressed against the side wall of the base 11. The tooling plate 2 is pressed against the side wall of the base 11 with the detection port 1120 (i.e., the inner side of the first side plate 112) through the second buckle 115, which further increases the stability of the tooling plate 2 in the installation groove 110, and makes the first reinforcement plate 5 close to the battery cell 10, avoiding the gap between the tooling plate 2 and the battery cell 10, and ensuring the measurement accuracy of the temperature measuring component 3. Specifically, two second buckles 115 are provided on the bottom plate 111, and each second buckle 115 is respectively installed in the avoidance space surrounded by the corresponding second side plate 113, and a second buckle 115 is arranged at an interval with a first buckle 114.

[0059] like Figure 5 and Figure 7 As shown, a boss 1110 is provided on the bottom plate 111, and the boss 1110 is used to support and raise the height of the tooling plate 2 to increase the height of the first clip 114 and the second clip 115, thereby ensuring that the first clip 114 and the second clip 115 have a better elastic deformation effect, thereby avoiding large obstruction or jamming of the first clip 114 and the second clip 115 when the tooling plate 2 is disassembled and assembled (that is, the clip head of the first clip 114 cannot pop out from the positioning groove 22), thereby realizing the disassembly and assembly operation of the tooling plate 2 in the installation groove 110.

[0060] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
