[0044] In some examples, the first BMS 210 may be arranged along the first direction with the battery module 100, and the first direction may be the length direction of the battery module 100.

[0045] Please refer to Figure 5 , 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 the second direction, and the second direction has an included angle with the first direction. In some examples, the included angle between the second direction and the first direction may be a right angle. In some examples, the first direction may be a horizontal direction, and the second direction may be a vertical direction.

[0046] Please refer to Figure 4, the wiring harness assembly 500 includes a first wiring harness 510 and a second wiring harness 530.

The second wiring harness 530 is used to connect the adapter 300 and the second connection part 230. The adapter 300 is mainly used to connect the first wiring harness 510 and the second wiring harness 530, so as to electrically connect the battery module 100 and the first BMS 210. The first BMS 210 can collect the status information of multiple battery cells in the battery module 100, such as parameters like temperature, voltage, current, etc., and can evaluate the overall health status of the battery module.

[0047] The adapter 300 can achieve electrical connections between different components or devices, and can also have functions such as signal transmission. In some examples, the adapter 300 can include contact parts, and the contact parts can be made of metal materials with good electrical conductivity, such as copper alloy, gold, silver, etc., to ensure low-resistance contact and support high current-carrying capacity. The contact parts can be divided into two forms: male and female, corresponding to male terminals and female terminals respectively, and can transmit electrical signals or power through physical contact.

[0048] Please refer to Figure 8 , Figure 9 and Figure 11 , in some embodiments, the adapter 300 includes a first adapter module 301 and a second adapter module 303 that are connected to each other. The first adapter module 301 and the second adapter module 303 are arranged along the second direction. One end of the first adapter module 301 facing away from the second adapter module 303 forms a third connection part 310, and one end of the second adapter module 303 facing away from the first adapter module 301 forms a fourth connection part 330.

[0049] In these embodiments, the adapter 300 includes a first adapter module 301 and a second adapter module 303 that are connected to each other. The first adapter module 301 and the second adapter module 303 are arranged along the second direction. One end of the first adapter module 301 facing away from the second adapter module 303 forms a third connection part 310, and one end of the second adapter module 303 facing away from the first adapter module 301 forms a fourth connection part 330. In this way, the third connection part 310 and the fourth connection part 330 of the adapter 300 are arranged along the second direction.

[0050] In some examples, there may be an electrical connection between the first adapter module 301 and the second adapter module 303. In this way, the wire harness of the third wiring part 310 of the first adapter module 301 is connected to the first wiring part 110, and the wire harness of the fourth wiring part 330 of the second adapter module 303 is connected to the second wiring part 230, realizing the electrical connection between the first wiring part 110 and the second wiring part 230.

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

[0052] In some embodiments, the adapter 300 further includes an installation module 304. The installation module 304 faces the first sub-bracket 670 on the side of the second adapter module 303 and is connected to the first sub-bracket 670.

[0053] The connection between the installation module 304 and the first sub-bracket 670 may be a detachable connection, such as a snap connection.

[0054] Among them, the first BMS 210, as the battery management system in the battery pack, may have one or more of the following functions. For example: In the first aspect, it can be used to continuously collect the status information of each battery cell in the battery module, such as parameters like temperature, voltage, and current, and evaluate the overall health status of the battery module accordingly. In the second aspect, 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). In the third aspect, it can prevent problems such as overcharging, over-discharging, and overheating of the battery. For example, when an abnormal situation is detected, it can cut off the circuit or send an alarm signal to the external control system. In the fourth aspect, it can balance the power levels between each battery cell by active or passive methods, thereby extending the service life of the entire battery pack. In the fifth aspect, it can also be equipped with a standardized communication protocol such as the CAN bus to exchange data with other in-vehicle electronic devices.

[0055] Please combine Figure 6, in some embodiments, the adapter 300 includes a third wiring portion 310 and a fourth wiring portion 330 that are connected to each other. Along the second direction, the third wiring portion 310 is located between the fourth wiring portion 330 and the first wiring portion 110, or rather, the fourth wiring portion 330 is located on the side of the third wiring portion 310 away from the first wiring portion 110. The first wire harness 510 is respectively connected to the first wiring portion 110 and the third wiring portion 310, and the second wire harness 530 is respectively connected to the fourth wiring portion 330 and the second wiring portion 230.

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

[0057] Please refer to Figure 7 and Figure 8 , in some embodiments, the battery pack 10 includes a mounting bracket 600. The mounting bracket 600 includes a first support portion 610 and a second support portion 630 arranged along the second direction. At least part of the adapter 300 is disposed on the side of the first support portion 610 facing away from 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 can achieve arranging the adapter 300 and the first BMS 210 along the second direction.

[0058] The connection between the first BMS 210 and the second support portion 630 can be in a screwed connection, snap connection or other ways.

[0059] In some embodiments, the adapter 300 can be directly mounted on the side of the first support portion 610 facing away from the second support portion 630, and the connection between the adapter 300 and the first support portion 610 can be in a screwed connection, snap connection or other ways.

[0060] Please refer to Figure 8 , in some embodiments, at least part of the adapter 300 can be disposed on the side of the first support portion 610 facing away from the second support portion 630 through a first auxiliary bracket 670. The battery pack further includes the first auxiliary bracket 670. One end of the first auxiliary bracket 670 is connected to the first support portion 610, and the opposite end extends along the side facing away from the second support portion 630. The adapter 300 is mounted on the side of the first auxiliary bracket 670 facing the first BMS 210.

[0061] In these embodiments, the adapter 300 and the first auxiliary bracket 670 can be connected by means such as screwing or clamping. The adapter 300 is installed on the side of the first auxiliary bracket 670 facing the first BMS 210, thereby reducing the wiring distance of the first wire harness 510 and the second wire harness 530.

[0062] By fixedly installing the adapter 300 through the first auxiliary bracket 670, 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, facilitating the connection of the first wire harness 510 to the first wiring portion 110 and the third wiring portion 310 respectively, and the second wire harness 530 to the fourth wiring portion 330 and the second wiring portion 230 respectively.

[0063] Please refer to Figure 5 and 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 away from the second support portion 630.

[0064] There are multiple battery cells in the battery module, and the number of electrical signals collected by a single BMS is limited. Multiple BMSs can be set. In these embodiments, the second BMS 250 is set. By cooperating with the first BMS 210, the second BMS 250 jointly collects the status information of multiple battery cells in the battery module 100, such as parameters such as temperature, voltage, and current, and can evaluate the overall health status of the battery module. In some examples, the second BMS 250 can be used as the main BMS, and the first BMS 210 can be used as the slave BMS. The second BMS 250 is used to manage and control the first BMS 210, and the second BMS 250 can also be used to manage and control the working status of electrical components such as relays in the battery pack 10.

[0065] The second BMS 250 is located on the side of the first support portion 610 away from the second support portion 630. At the same time, the first BMS 210 is installed on the side of the second support portion 630 facing the first support portion 610. Or rather, the first BMS 210 is located between the second support portion 630 and the first support portion 610. The first support portion 610 and the second support portion 630 are arranged along the second direction. In this way, the first BMS 210 and the second BMS 250 can be arranged along the second direction. Since the first BMS 210 is arranged along the first direction with the battery module 100, and the first BMS 210 and the second BMS 250 are arranged along the second direction, the first BMS 210 and the second BMS 250 are located on one side of the battery module 100 in the length direction, without occupying the space on both sides in the height direction of the battery module 100, enabling the battery module 100 to have a larger height, thereby increasing the number of battery cells of the battery module 100, and further increasing the endurance of the battery module 100. In addition, the first BMS 210 and the second BMS 250 are located on one side of the battery module 100 in the length direction, and the first BMS 210 and the second BMS 250 are arranged along the second direction, making the structure between the first BMS 210, the second BMS 250 and the battery module 100 more compact, enabling the battery pack to have a smaller volume. When this battery pack is applied to a vehicle, the occupation of the vehicle space can be reduced. Specifically, the length direction of the battery module 100 can correspond to the length direction of the vehicle, and the width direction of the battery module 100 can correspond to the width direction of the vehicle and be placed accordingly.

[0066] Please refer to Figure 1 and Figure 3 , in some embodiments, the battery pack 10 further includes a box body 101, a cover body 103, and a first overcurrent component 700. The cover body 103 is connected to the box body 101 and forms an installation cavity 104. The second BMS 250 is installed in the installation cavity 104, and the first overcurrent component 700 is installed on the box body 101. The second BMS 250 includes a fifth wiring portion 251 away from the cover body 103. The wiring harness assembly 500 further includes a third wiring harness 550. The third wiring harness 550 is used to connect the fifth wiring portion 251 and the first overcurrent 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 body 103 and the first overcurrent component 700. Thus, the third wiring harness 550 is not likely to interfere with the cover body 103. In these embodiments, the cover body 103 and the box body 101 can be connected by means such as screwing or clamping. The cover body 103 can be covered on the box body 101 along the second direction to shield the installation cavity 104. The mounting bracket 600 is installed in the installation cavity 104, and the second BMS 250 is installed in the installation cavity 104.

[0068] Please refer to Figure 1 and Figure 3The first flow member 700 is installed in the box 101. In some examples, the first flow member 700 can specifically be a vehicle communication interface. Part of the first flow member 700 is located outside the installation cavity 104, and part of it is installed in the box 101 and connected to the third wiring harness 550 located in the installation cavity 104.

[0069] In these examples, the vehicle communication interface can connect the second BMS 250 with other control units of the vehicle through the third wiring harness 550, so that the battery status information can be accurately transmitted to the vehicle controller (VCU), and the vehicle controller can make appropriate decisions based on this information.

[0070] Please combine Figure 8 In some embodiments, the first current flowing member 700 includes a sixth wiring portion 710.

[0071] In these embodiments, an avoidance gap 611 is provided so that the other end of the third wiring harness 550 can pass through the first support portion 610 to connect to the sixth wiring portion 710, thereby facilitating the connection between the first current-passing member 700 and the second BMS 250, while reducing the wiring distance and the space occupied by the third wiring harness 550.

[0072] Please combine Figure 9 In some embodiments, the mounting bracket 600 also includes a second sub-bracket 650, the second sub-bracket 650 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 respectively 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 avoidance gap 611.

[0073] In these embodiments, the second sub-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 installation portion 653 away from the first support portion 610. The first connecting portion 651 is located around the avoidance gap 611, which can strengthen the avoidance gap 611 and prevent it from deformation.
