[0038] Firstly, please combine Figure 1 This application provides a battery pack 10, which may include a housing 101 and a cover 103. The cover 103 is connected to the housing 101 and forms a mounting cavity 104, in which a battery module 100 may be installed.

[0039] Please combine Figure 2 as well as Figure 3 The battery pack 10 includes: a battery module 100, a first BMS 210, an adapter 300, and a wiring harness assembly 500. Please refer to... Figure 4 as well as Figure 5 The battery module 100 is provided with a first wiring portion 110; the first BMS 210 and the battery module 100 are arranged along a first direction, the first BMS 210 is provided with a second wiring portion 230, the second wiring portion 230 and the first wiring portion 110 are arranged along a second direction, the second direction and the first direction have an angle; along the second direction, at least a portion of the adapter 300 is disposed between the first wiring portion 110 and the second wiring portion 230; the wiring harness assembly 500 includes a first wiring harness 510 and a second wiring harness 530 that are electrically connected, the first wiring harness 510 is used to connect the first wiring portion 110 and the adapter 300, and the second wiring harness 530 is used to connect the adapter 300 and the second wiring portion 230, so that the battery module 100 is electrically connected to the first BMS 210.

[0040] The battery module 100 and the first BMS 210 are electrically connected via a wiring harness assembly 500. However, due to the considerable distance between the battery module 100 and the first BMS 210, and the potential presence of copper busbars and other electrical components between them, connecting the wiring harness presents difficulties. To facilitate assembly, in this embodiment, an adapter 300 is provided, with at least a portion of the adapter 300 positioned between the first wiring portion 110 and the second wiring portion 230 along the second direction. During assembly, the first wiring harness 510 can be used to connect the first wiring section 110 to the adapter 300, and the second wiring harness 530 can be used to connect the adapter 300 to the second wiring section 230, thereby enabling the battery module 100 to be electrically connected to the first BMS 210. The second wiring section 230 and the first wiring section 110 are arranged along a second direction. Along the second direction, at least part of the adapter 300 is disposed between the first wiring section 110 and the second wiring section 230, resulting in a shorter wiring distance and simpler operation.

[0041] In these embodiments, the battery module 100 may include multiple battery cells, which can be combined in series or in parallel. In some examples, a battery cell may include two opposite sides along a first direction, a first end and a second end along a second direction, the bottom surface of the battery cell may be located on the side of the first end facing away from the second end, and the second end may have a terminal post. Multiple battery cells may be stacked along the first direction. The battery module 100 has a length direction, a width direction, and a height direction. The length direction of the battery module 100 is the stacking direction of the multiple battery cells, i.e., the first direction. The width direction of the battery module 100 is the width direction of the battery cells, and the height direction of the battery module 100 is the height direction of the battery cells, i.e., the second direction. When the battery module 100 is installed in a battery pack, the length direction of the battery module 100 may be consistent with the length direction of the battery pack, the width direction of the battery module 100 may be consistent with the width direction of the battery pack, and the height direction of the battery module 100 may be consistent with the height direction of the battery pack.

[0042] Please combine Figure 5 The battery module 100 is provided with a first wiring portion 110. In some embodiments, the first wiring portion 110 may include the terminals of a plurality of battery cells.

[0043] In some embodiments, the battery pack (10) may further include a CCS (Cell Connection System) 400, which may be connected to the first wiring part 110. The CCS 400 may be installed on one side of the battery module 100, specifically on the side where the terminals of the battery modules 100 cells are located. The CCS 400 (Cell Connection System) is connected to the terminals of the battery modules 100 cells. The CCS 400 can connect the battery modules 100 cells into a whole, ensuring that the current flows smoothly between the cells, thereby realizing the effective storage and release of electrical energy.

[0044] In some examples, the first BMS210 may be arranged with the battery module 100 along a first direction, which may be the length direction of the battery module 100.

[0045] Please combine Figure 5 The first BMS 210 is provided with a second wiring portion 230, which is arranged along a second direction with the first wiring portion 110. The second direction forms an angle with the first direction. In some examples, the angle between the second direction and the first direction can be a right angle. In some examples, the first direction can be a horizontal direction and the second direction can be a vertical direction.

[0046] Please combine Figure 4The wiring harness assembly 500 includes a first wiring harness 510 and a second wiring harness 530. The first wiring harness 510 is used to connect the first terminal 110 and the adapter 300. In some examples, the first wiring harness 510 can be connected to the CCS 400, and the CCS 400 can be connected to the first terminal 110, thereby enabling the connection between the first terminal 110 and the first wiring harness 510. The second wiring harness 530 is used to connect the adapter 300 and the second terminal 230. The adapter 300 is mainly used to connect the first wiring harness 510 and the second wiring harness 530, thereby electrically connecting the battery module 100 to the first BMS 210. The first BMS 210 collects status information of multiple cells in the battery module 100, such as parameters like temperature, voltage, and current, and can assess the overall health status of the battery module.

[0047] The adapter 300 enables electrical connections between different components or devices and can also perform signal transmission functions. In some examples, the adapter 300 may include contacts made of a highly conductive metallic material, such as copper alloy, gold, or silver, to ensure low-resistance contact and support high current carrying capacity. The contacts can be either male or female, corresponding to male terminals and female terminals respectively, and can transmit electrical signals or power through physical contact.

[0048] Please combine Figure 8 , Figure 9 as well as Figure 11 In some embodiments, the adapter 300 includes a first adapter module 301 and a second adapter module 303 connected to each other. The first adapter module 301 and the second adapter module 303 are arranged along a second direction. The end of the first adapter module 301 opposite to the second adapter module 303 forms a third wiring portion 310, and the end of the second adapter module 303 opposite to the first adapter module 301 forms a fourth wiring portion 330.

[0049] In these embodiments, the adapter 300 includes a first adapter module 301 and a second adapter module 303 connected to each other. The first adapter module 301 and the second adapter module 303 are arranged along a second direction. The end of the first adapter module 301 opposite to the second adapter module 303 forms a third wiring portion 310, and the end of the second adapter module 303 opposite to the first adapter module 301 forms a fourth wiring portion 330. Thus, the third wiring portion 310 and the fourth wiring portion 330 of the adapter 300 are arranged along the second direction.

[0050] In some examples, the first adapter module 301 and the second adapter module 303 can be electrically connected. In this way, the first adapter module 301 is connected to the wiring harness of the first adapter module 110 through the third wiring portion 310, and the second adapter module 303 is connected to the wiring harness of the second adapter module 230 through the fourth wiring portion 330, thereby realizing the electrical connection between the first adapter module 110 and the second adapter module 230.

[0051] In some examples, the first adapter module 301 and the second adapter module 303 may be mechanically connected, serving only to fix the first wire harness 510 and the second wire harness 530. The first wire harness 510 is fixed by the third wiring portion 310 of the first adapter module 301, and the second wire harness 530 is fixed by the fourth wiring portion 330 of the second adapter module 303, which facilitates the electrical connection of the first wire harness 510 and the second wire harness 530.

[0052] In some embodiments, the adapter 300 further includes a mounting module 304, which is connected to the first sub-bracket 670 on the side of the second adapter module 303 facing the first sub-bracket 670.

[0053] The mounting module 304 and the first auxiliary bracket 670 can be detachably connected, for example, by snap-fit.

[0054] The first BMS210, as the battery management system in the battery pack, can have one or more of the following functions: First, it can continuously collect status information about each cell in the battery module, such as temperature, voltage, and current, and assess the overall health of the battery module accordingly. Second, based on the collected data, the BMS can calculate key indicators such as SOC (State of Charge), SOH (State of Health), and SOP (State of Power). Third, it can prevent problems such as overcharging, over-discharging, and overheating of the battery. For example, when an abnormality is detected, it can cut off the circuit or send an alarm signal to the external control system. Fourth, it can balance the charge levels between individual cells through active or passive methods, thereby extending the lifespan of the entire battery pack. Fifth, it can also be equipped with standardized communication protocols such as CAN bus to exchange data with other vehicle electronic devices.

[0055] Please combine Figure 6In some embodiments, the adapter 300 includes a third connector 310 and a fourth connector 330 connected to each other. Along the second direction, the third connector 310 is located between the fourth connector 330 and the first connector 110, or in other words, the fourth connector 330 is located on the side of the third connector 310 away from the first connector 110. A first wiring harness 510 is connected to both the first connector 110 and the third connector 310, and a second wiring harness 530 is connected to both the fourth connector 330 and the second connector 230.

[0056] In these embodiments, by positioning the third wiring portion 310 between the fourth wiring portion 330 and the first wiring portion 110 along the second direction, the first wiring harness 510 can connect the first wiring portion 110 and the third wiring portion 310 via a shorter path, and the second wiring harness 530 can connect the fourth wiring portion 330 and the second wiring portion 230 via a shorter path, thereby reducing the wiring distance of the first wiring harness 510 and the second wiring harness 530.

[0057] Please combine Figure 7 as well as Figure 8 In some embodiments, the battery pack 10 includes a mounting bracket 600, which includes a first support portion 610 and a second support portion 630 arranged along a second direction. At least a portion of the adapter 300 is disposed on the side of the first support portion 610 opposite to the second support portion 630, and the first BMS 210 is mounted on the side of the second support portion 630 facing the first support portion 610. This allows the adapter 300 and the first BMS 210 to be arranged along the second direction.

[0058] The first BMS210 and the second support 630 can be connected by means of screws, snaps, or other methods.

[0059] In some embodiments, the adapter 300 can be directly installed on the side of the first support 610 away from the second support 630, and the adapter 300 and the first support 610 can be connected by means of screw connection, snap connection or other methods.

[0060] Please combine Figure 8 In some embodiments, at least part of the adapter 300 may be disposed on the side of the first support portion 610 away from the second support portion 630 via the first sub-bracket 670. The battery pack also includes the first sub-bracket 670, one end of which is connected to the first support portion 610, and the other end of which extends along the side away from the second support portion 630. The adapter 300 is mounted on the side of the first sub-bracket 670 facing the first BMS210.

[0061] In these embodiments, the adapter 300 and the first sub-bracket 670 can be connected by screws, snaps, or other means. The adapter 300 is installed on the side of the first sub-bracket 670 facing the first BMS210, thereby reducing the wiring distance between the first harness 510 and the second harness 530.

[0062] The adapter 300 is fixedly installed by the first bracket 670, so that the third wiring portion 310 and the fourth wiring portion 330 of the adapter 300 can be installed along the arrangement direction of the first support portion 610 and the second support portion 630, so that the first wire harness 510 can be connected to the first wiring portion 110 and the third wiring portion 310 respectively, and the second wire harness 530 can be connected to the fourth wiring portion 330 and the second wiring portion 230 respectively.

[0063] Please combine Figure 5 as well as Figure 6 In some embodiments, the battery pack 10 further includes a second BMS 250, which is electrically connected to the first BMS 210 and is located on the side of the first support portion 610 opposite to the second support portion 630.

[0064] A battery module contains multiple battery cells. Since a single Battery Management System (BMS) can only collect a limited number of electrical signals, multiple BMSs can be configured. In these embodiments, a second BMS 250 is used. The second BMS 250 works in conjunction with the first BMS 210 to collect status information of the multiple battery cells in the battery module 100, such as parameters like temperature, voltage, and current, and can assess the overall health of the battery module. In some examples, the second BMS 250 can act as the master BMS, and the first BMS 210 as the slave BMS. The second BMS 250 manages and controls the first BMS 210. The second BMS 250 can also manage and control the operating status of electrical components in the battery pack 10, such as relays.

[0065] The second BMS250 is located on the side of the first support portion 610 away from the second support portion 630, while the first BMS210 is installed on the side of the second support portion 630 facing the first support portion 610. In other words, the first BMS210 is located between the second support portion 630 and the first support portion 610. The first and second support portions 610 are arranged along a second direction, thus allowing the first BMS210 and second BMS250 to be arranged along the second direction. Because the first BMS210 and battery module 100 are arranged along the first direction, and the first BMS210 and second BMS250 are arranged along the second direction, the first BMS210 and second BMS250 are located on one side of the length direction of the battery module 100, without encroaching on the space on both sides of the height direction of the battery module 100. This allows the battery module 100 to be set at a larger height, thereby increasing the number of battery cells in the battery module 100 and thus increasing the battery module 100's range. Furthermore, the first BMS210 and the second BMS250 are located on one side of the length direction of the battery module 100, and are arranged along the second direction, making the structure between the first BMS210, the second BMS250 and the battery module 100 more compact, allowing the battery pack to have a smaller volume. When this battery pack is applied to a vehicle, it can reduce the encroachment on vehicle space. Specifically, the length direction of the battery module 100 can be aligned with the length direction of the vehicle, and the width direction of the battery module 100 can be aligned with the width direction of the vehicle.

[0066] Please combine Figure 1 and Figure 3 In some embodiments, the battery pack 10 further includes a housing 101, a cover 103, and a first current-passing component 700. The cover 103 is connected to the housing 101 and forms a mounting cavity 104. A second BMS 250 is mounted in the mounting cavity 104, and the first current-passing component 700 is mounted in the housing 101. The second BMS 250 includes a fifth wiring portion 251 located away from the cover 103. The wiring harness assembly 500 further includes a third wiring harness 550, which is used to connect the fifth wiring portion 251 and the first current-passing component 700.

[0067] In these embodiments, the third wiring harness 550 is used to connect the fifth wiring portion 251 of the second BMS 250 away from the cover 103 and the first current-passing component 700, thereby making it less likely for the third wiring harness 550 to interfere with the cover 103. In these embodiments, the cover 103 and the housing 101 can be connected by screws, snaps, or other methods. The cover 103 can be placed over the housing 101 along the second direction, thereby covering the mounting cavity 104. The mounting bracket 600 is mounted in the mounting cavity 104, and the second BMS 250 is mounted in the mounting cavity 104.

[0068] Please combine Figure 1 and Figure 3The first current-passing component 700 is installed on the housing 101. In some examples, the first current-passing component 700 can be a vehicle communication interface. Part of the first current-passing component 700 is located outside the mounting cavity 104, and part is installed on the housing 101 and connected to the third wiring harness 550 located in the mounting cavity 104.

[0069] In these examples, the vehicle communication interface can connect the second BMS250 to other vehicle control units via the third wiring harness 550, enabling accurate transmission of battery status information to the vehicle controller (VCU), which can then make appropriate decisions based on this information.

[0070] Please combine Figure 8 In some embodiments, the first overcurrent member 700 includes a sixth wiring portion 710. Along the second direction, at least a portion of the sixth wiring portion 710 is located on the side of the first support portion 610 away from the fifth wiring portion 251. The first support portion 610 has a clearance notch 611. One end of the third wiring harness 550 is connected to the fifth wiring portion 251, and the other end passes through the clearance notch 611 for connecting to the sixth wiring portion 710.

[0071] In these embodiments, a clearance notch 611 is provided so that the other end of the third wire harness 550 can pass through the first support portion 610 to connect to the sixth wiring portion 710, which facilitates the connection between the first current-carrying component 700 and the second BMS 250, while reducing the wiring distance and also reducing the space occupied by the third wire harness 550.

[0072] Please combine Figure 9 In some embodiments, the mounting bracket 600 further includes a second auxiliary bracket 650, which includes a first connecting portion 651 and a mounting portion 653. The mounting portion 653 is located on the side of the first support portion 610 away from the second support portion 630. The first connecting portion 651 is connected to the mounting portion 653 and the side of the first support portion 610 facing the mounting portion 653, and the first connecting portion 651 is located around the clearance notch 611.

[0073] In these embodiments, the second bracket 650 can be used to install electrical components, such as a TBOX signal box. The TBOX signal box can be installed on the side of the mounting part 653 away from the first support part 610. The first connecting part 651 is located around the clearance notch 611 and can strengthen the clearance notch 611 to prevent it from deforming.

[0074] The mounting part 653 and the first support part 610 can be arranged at intervals to facilitate the passage of the third wire harness 550 through the clearance gap 611.

[0075] Please combine Figure 9In some embodiments, there are two first connecting portions 651, which are arranged along a third direction and perpendicular to the second direction. The two connecting portions 651 are respectively connected to the opposite sides of the mounting portion 653, and the clearance notch 611 is located between the two connecting portions 651.

[0076] The clearance notch 611 is located between the two first connecting parts 651, thereby reinforcing both sides of the clearance notch 611 along a third direction to prevent deformation.

[0077] Please combine Figure 9 In some embodiments, the mounting bracket 600 further includes an intermediate connecting portion 660, one end of which is connected to the side of the first support portion 610 facing the second support portion 630, and the other end is connected to the second support portion 630. The intermediate connecting portion 660 is located around the clearance notch 611.
