[0031] With the continuous development of battery technology, battery packs are being used more and more widely. In order to ensure the normal operation of the battery pack, the battery management system needs to detect parameters such as voltage and temperature of the battery pack. Typically, the voltage of the battery pack is collected through a voltage sampling harness, and the temperature of the battery pack is detected through a temperature sensor.

[0032] In related technologies, there are generally two ways to connect the voltage sampling harness and temperature sensor to the battery pack. One method is that the voltage sampling harness and temperature sensor are each connected to the battery pack through independent components. For example, the voltage sampling harness can be connected to the conductive part of the battery pack, such as a busbar, through independent metal terminals, while the temperature sensor is fixed in a slot on the blister pack bracket of the battery pack. However, this method of installing the voltage sampling harness and temperature sensor separately involves the installation of multiple different components, resulting in more installation steps and increased production costs. The other method is to install the voltage sampling harness and temperature sensor through sampling terminals. These sampling terminals are usually of a split structure, typically including a connecting piece and a mounting piece. The connecting piece is used to connect to the conductive part of the battery pack, such as a busbar, and the mounting piece is used to install the temperature sensor and voltage sampling harness. The specific installation process can be that the temperature sensor and voltage sensor are first installed on the mounting piece, and then the mounting piece is connected to the connecting piece, thus realizing the installation of the sampling terminal with the temperature sensor and voltage sampling harness. However, this also involves the installation of multiple different components, resulting in more installation steps and increased production costs.

[0033] Based on this, embodiments of this application provide a sampling terminal. In practical applications, the sampling terminal can be used to sample the temperature and voltage of a battery pack. The sampling terminal of this application will be described in detail below with reference to the accompanying drawings.

[0034] This application also discloses a battery pack, which includes the sampling component described in the above embodiments.

[0035] Reference Figures 1-4 The sampling terminal provided in this application embodiment has a first direction X and includes: a terminal body 1, which is used to connect to a battery pack. A first mounting groove 10 and a second mounting groove 11 are provided on the terminal body 1 at intervals along the first direction X. The first mounting groove 10 is used to install a temperature sensor, and the second mounting groove 11 is used to install a voltage sampling wire harness. The terminal body 1, the first mounting groove 10 and the second mounting groove 11 are integrally formed structures.

[0036] Specifically, the first direction X is as follows: Figure 1 The X-axis direction shown can be specifically the length direction of the terminal body 1. The terminal body 1 is made of a metal material with good thermal and electrical conductivity, such as copper or nickel. The terminal body 1 is connected to the conductive part of the battery pack, and can transmit the voltage and temperature of the battery pack.

[0037] The first mounting groove 10 is disposed on the terminal body 1. The shape and size of the first mounting groove 10 are adapted to the shape and size of the temperature sensor. The temperature sensor is disposed in the first mounting groove 10. The temperature of the battery pack can be transmitted to the temperature sensor through the first mounting groove 10, so that the temperature sensor can detect the temperature of the battery pack.

[0038] The second mounting slot 11 is disposed on the terminal body 1 and is spaced a certain distance from the first mounting slot 10 along the first direction X. This distance can be specifically set according to the actual situation, as long as there is no interference when the temperature sensor and the voltage sampling harness are installed. The shape and size of the first mounting slot 10 are adapted to the shape and size of the voltage sampling harness, so that the voltage sampling harness can be connected in the second mounting slot 11. The voltage of the battery pack can be transmitted to the voltage sampling harness through the second mounting slot 11, so that the voltage sampling harness can collect the voltage of the battery pack.

[0039] The terminal body 1, the first mounting groove 10, and the second mounting groove 11 can be integrally formed using die-casting or other integral molding processes. In this embodiment, by providing the first mounting groove 10 and the second mounting groove 11 on the terminal body 1, and making the terminal body 1, the first mounting groove 10, and the second mounting groove 11 an integral structure, during installation, only the temperature sensor needs to be directly installed into the first mounting groove 10, and the voltage sampling harness needs to be installed into the second mounting groove 11, without assembling the separate components of the sampling terminal. This simplifies the installation process and reduces production costs. Furthermore, by directly placing the temperature sensor in the second mounting groove 11, the terminal body 1 can act as a heat conduction medium to directly transfer the temperature of the battery pack to the temperature sensor, thereby improving the accuracy of temperature sampling.

[0040] Optionally, the first mounting slot 10 is a cylindrical mounting slot.

[0041] like Figures 1-2 As shown, the first mounting groove 10 is a cylindrical mounting groove. The cylindrical shape of the mounting groove gives the inner wall of the first mounting groove 10 a certain curvature. In this way, when the temperature sensor is installed in the first mounting groove 10, the inner wall of the first mounting groove 10 can provide support for the temperature sensor, preventing the temperature sensor from slipping out of the first mounting groove 10 during installation. This reduces the need for adjustments and repetitive operations during installation, improves the work efficiency on the production line, and reduces production costs.

[0042] In some embodiments, the first mounting groove 10 includes a first side 101 and a second side 102 disposed opposite to each other along the second direction Z, the second side 102 being provided with a first opening 1021, and the second direction Z intersecting the first direction X.

[0043] Specifically, such as Figure 2 and Figure 3 As shown, the second direction Z is as follows Figure 3The Z-axis direction shown can be specifically the thickness direction of the terminal body 1. The second direction Z intersects the first direction X, and preferably, the second direction Z is perpendicular to the first direction X. The first mounting groove 10 includes a first side 101 and a second side 102 disposed opposite to each other along the second direction Z. The first side 101 is the bottom end of the first mounting groove 10 along the second direction Z, and the bottom end is closed. The second side 102 is the top end of the first mounting groove 10 along the second direction Z. The second side 102 is provided with a first opening 1021. When installing the temperature sensor, the temperature sensor can be inserted into the first mounting groove 10 through the first opening 1021. In order to further fix the temperature sensor in the first mounting groove 10, sealant can be injected into the first mounting groove 10 through the first opening 1021, so that the sealant can completely fill the gap between the temperature sensor and the groove wall of the first mounting groove 10. After the sealant cures, a sealant layer is formed, which can fix the temperature sensor in the first mounting groove 10. By providing the first opening 1021, the insertion of the temperature sensor into the first mounting groove 10 and the injection of sealant can be realized.

[0044] Optionally, it also includes a blocking block 13. The first mounting groove 10 includes a third side 103 and a fourth side 104 disposed opposite to each other along the first direction X. The fourth side 104 is close to the second mounting groove 11. The blocking block 13 is disposed in the third side 103. The fourth side 104 is provided with a second opening 1040.

[0045] Specifically, such as Figure 2 and Figure 3 As shown, the first mounting groove 10 also includes a third side 103 and a fourth side 104 disposed opposite to each other along the first direction X. The third side 103 can be a first mounting groove 10 such as Figure 3 As shown, along the right side of the first direction X, the third side 103 is away from the second mounting groove 11. The blocking block 13 is disposed within the third side 103 of the third mounting groove. The blocking block 13 is integrally formed with the first mounting groove 10. The fourth side 104 is the first mounting groove 10. Figure 3 As shown, on the left side along the first direction X, the fourth side 104 is close to the second mounting groove 11. The fourth side 104 is provided with a second opening 1040. When installing the temperature sensor, the temperature sensor can also be inserted into the first mounting groove 10 through the second opening 1040, and the temperature sampling harness can also be connected to the temperature sensor through the second opening 1040.

[0046] To further secure the temperature sensor within the first mounting groove 10, sealant can be injected into the first mounting groove 10 through the first opening 1021. This allows the sealant to completely fill the gap between the temperature sensor and the groove wall of the first mounting groove 10. After the sealant cures, a sealant layer is formed, allowing the temperature sensor to be fixed within the first mounting groove 10. In this embodiment, a blocking block 13 is provided on the second side 102 of the first mounting groove 10. During the sealing process, the blocking block 13 can prevent the sealant from flowing out of the first mounting groove 10, thereby reducing sealant outflow, improving production efficiency, and lowering production costs.

[0047] Optionally, the terminal body 1 includes a first outer side wall 141 and a second outer side wall 142 disposed opposite to each other along the third direction Y. Both the first outer side wall 141 and the second outer side wall 142 are provided with a recess 143, which is used to fix the terminal body 1. The third direction Y intersects with the first direction X.

[0048] Specifically, such as Figures 1-4 As shown, the third party directs Y as follows: Figure 1 The Y-axis direction shown is the width direction of the terminal body 1. The third direction Y, the second direction Z and the first direction X intersect each other. Preferably, the third direction Y, the first direction X and the second direction Z are perpendicular to each other.

[0049] Terminal body 1 includes a first outer side wall 141 and a second outer side wall 142 disposed opposite each other along a third direction Y. The first outer side wall 141 may be disposed with respect to the first mounting groove 10. Figure 4 As shown, the outer sidewall opposite the inner sidewall on the left side along the three directions Y, the second outer sidewall 142 can be the same as the first mounting groove 10. Figure 4 As shown, the inner sidewalls on the right side of the third direction Y, opposite to each other, have recesses 143 on both the first outer sidewall 141 and the second outer sidewall 142. The recesses 143 are recessed grooves on the first and second outer sidewalls 141 and 142, respectively, and can be symmetrically arranged. The shape and size of the recesses 143 can be specifically set according to actual needs, and can be rectangular, circular, or other suitable shapes. In practical applications, by providing the recesses 143, when the temperature sensor in the first mounting groove 10 is fixed with glue, the recesses 143 cooperate with the external fixing device to fix the terminal body 1, facilitating the glue-filling process, improving production efficiency, and reducing production costs.

[0050] Optionally, a plurality of recesses 143 are provided on both the first outer side wall 141 and the second outer side wall 142, and the plurality of recesses 143 are spaced apart along the first direction X on the first outer side wall 141 and the second outer side wall 142. In practical applications, by providing a plurality of recesses 143 on both the first outer side wall and the second outer side wall 142, when the temperature sensor in the first mounting groove 10 is fixed with glue, the plurality of recesses 143 are used to cooperate with the external fixing device, providing multiple support points to fix the terminal body 1, facilitating the glue-filling process, further improving production efficiency and reducing production costs. For example, the number of recesses 143 can be 2, 3, 4, etc., and this application embodiment does not specifically limit this.

[0051] Optionally, the first mounting groove 10 includes a first end 105 and a second end 106 disposed opposite to each other along the first direction X. The first end 105 is disposed at the end of the first mounting groove 10 away from the second mounting groove 11, and the first end 105 is provided with a connecting piece 15 for welding to the battery pack. The second end 106 is connected to the second mounting groove 11.

[0052] Specifically, such as Figures 1-3 As shown, the first mounting groove 10 includes a first end 105 and a second end 106 disposed opposite each other along a first direction X. The first end 105 is located at the end of the first mounting groove 10 away from the second mounting groove 11. The first end 105 can be an extension extending outward from the end of the first mounting groove 10 along the first direction X. A connecting piece 15 is disposed at the first end 105. The connecting piece 15 has a sheet-like structure and is used to weld to the conductive part of the battery pack. The shape of the connecting piece 15 can be designed according to the shape of the corresponding welding part on the battery pack, such as a rectangle or a circle. During installation, the connecting piece 15 is welded to the conductive part of the battery pack using welding processes such as spot welding or laser welding to achieve electrical connection between the sampling terminal and the battery pack.

[0053] The second end 106 is disposed at one end of the first mounting groove 10 near the first mounting groove 10. The second end 106 can be an outward extension of the other end of the first mounting groove 10 in the first direction X. The second end 106 is connected to the second mounting groove 11, and the voltage sampling harness is connected inside the second mounting groove 11.

[0054] In some alternative embodiments, the terminal body 1 may only have the first mounting slot 10, in which case the sampling terminal is only used to measure the temperature of the battery pack. Alternatively, the terminal body 1 may only have the second mounting slot 11, in which case the sampling terminal is only used to measure the voltage of the battery pack.

[0055] In some alternative embodiments, such as Figures 1-4As shown, the second mounting groove 11 has a third opening 110 on both sides along the first direction X, and a fourth opening 111 at the top of the second mounting groove 11 along the second direction Z. The voltage sampling wire harness can be inserted into the second mounting groove 11 from the third opening 110, and the second mounting groove 11 can be squeezed and deformed to close the fourth opening 111. In this way, the voltage sampling wire harness can be pressed into the second mounting groove 11, so that the voltage sampling wire harness can be electrically connected to the second mounting groove 11.

[0056] In summary, the sampling terminals of the embodiments of this application may include at least the following advantages:

[0057] In this embodiment, by providing a first mounting groove 10 and a second mounting groove 11 on the terminal body 1, and making the terminal body 1, the first mounting groove 10, and the second mounting groove 11 an integrally formed structure, during installation, the temperature sensor only needs to be directly installed into the first mounting groove 10, and the voltage sampling harness into the second mounting groove 11, without the need for assembling separate components of the sampling terminal. This simplifies the installation process and reduces production costs. Furthermore, by directly placing the temperature sensor within the second mounting groove 11, the terminal body 1 can act as a heat conduction medium to transfer the temperature of the battery pack to the temperature sensor, improving the accuracy of temperature sampling.

The voltage sampling harness can transmit the collected battery pack voltage to the BMS, enabling the BMS to monitor the battery voltage in real time and perform functions such as voltage balancing, overvoltage protection, and undervoltage protection. The temperature sampling harness can transmit the battery pack temperature information collected by the temperature sensor to the BMS, enabling the BMS to monitor the temperature changes of the battery pack, perform overheat protection and thermal management control, ensure that the battery pack operates within a suitable temperature range, and improve the safety and lifespan of the battery pack.
