[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0045] This application provides a battery pack; please refer to [link / reference]. Figure 1 and Figure 2The battery pack 1 includes a housing 10, which has a receiving cavity 11 for housing the battery module 20. The housing 10 serves as the overall frame structure of the battery pack 1, supporting the various components within the battery pack 1 and providing sealing protection to prevent interference from the external environment, thereby ensuring the stability of the battery pack 1 during use.

[0046] The battery pack 1 includes a drive control module 30, which is located within the receiving cavity 11. The drive control module 30 is used to control the rotation of the power module 2 within the vehicle. The drive control module 30 can be electrically connected to the battery module 20, which provides electrical energy to the drive control module 30. The drive control module 30 controls the current and voltage input to the power module 2 to control its speed, torque, etc. The power module 2 then converts the electrical energy into mechanical energy to drive corresponding vehicle components.

[0047] The drive control module 30 mainly includes a control board and a power board, which can be connected and communicate with each other through plug-ins.

[0048] In this embodiment, by placing the drive control module 30 within the housing cavity 11 of the battery pack 1, the space within the battery pack 1 can be fully utilized, thereby improving the integration of the battery pack 1. When the battery pack 1 is applied to a vehicle, it also allows for more space in the vehicle cabin, facilitating the arrangement of other vehicle components.

[0049] Furthermore, by placing the drive control module 30 within the housing cavity 11 of the battery pack 1, the drive control module 30 can be sealed and protected by the battery pack 1 itself, without the need to separately set up a sealing and protective support structure for the drive control module 30. This helps to save space and reduce production costs while achieving dust prevention and sealing.

[0050] In some embodiments, the battery pack 1 includes a plurality of drive control modules 30, which are spaced apart in the receiving cavity 11, i.e., the plurality of drive control modules 30 are dispersed in the receiving cavity 11 to avoid the heat generated by the drive control modules 30 during operation being too concentrated, thereby helping to reduce the heat dissipation requirements of the drive control modules 30 and thus reducing the overall production cost of the battery pack 1.

[0051] It should be noted that the position of the drive control module 30 within the housing cavity 11 can be adjusted according to specific drive requirements, i.e., the specific position of the corresponding power module 2, thereby making the position setting of the drive control module 30 within the battery pack 1 more flexible, which is beneficial for power distribution to the power modules 2 in different positions of the vehicle.

[0052] In some embodiments, multiple drive control modules 30 are connected in parallel, meaning that the power delivery on the multiple drive control modules 30 is independent of each other, thereby enabling each drive control module 30 to independently control and supply power to the corresponding power module 2, thus ensuring that the power module 2 can provide sufficient power output.

[0053] It should be noted that multiple drive control modules 30 can be connected in series, or partially in parallel and partially in series. The specific connection method between multiple drive control modules 30 can be designed and adjusted according to actual drive requirements, and no special limitation is made here.

[0054] In some embodiments, the battery pack 1 includes a plurality of drive control modules 30 and a plurality of first connection bars 50. Each first connection bar 50 is used to connect at least two drive control modules 30, and the at least two drive control modules 30 are connected in parallel through the first connection bar 50. By using the first connection bars 50 to connect the drive control modules 30 within the battery pack 1, compared to placing the drive control modules 30 outside the battery pack 1 and using wire harnesses for connection, the use of wire harness protection structures such as corrugated pipes can be reduced, thereby reducing the space occupation and lowering production costs.

[0055] In some embodiments, the receiving cavity 11 includes a plurality of first sub-receiving cavities 111, the drive control module 30 is disposed in the first sub-receiving cavity 111, and the housing 10 includes a first crossbeam 12, which is disposed between two first sub-receiving cavities 111. That is, the two drive control modules 30 can be separated by the first crossbeam 12 to reduce the risk of mutual interference between the two drive control modules 30, thereby improving the stability of the use of the drive control module 30.

[0056] In some examples, please refer to Figure 2 and Figure 3 A first through hole 121 is provided on the first crossbeam 12, extending through the first crossbeam 12 along its thickness direction. The first through hole 121 is used for the first connecting row 50 to pass through, connecting the drive control modules 30 in the two first sub-accommodating cavities 111. By providing the first through hole 121 on the first crossbeam 12 and arranging the first connecting row 50 to pass through the first through hole 121, the space utilization rate of the battery pack 1 in the height direction can be improved, thereby further improving the overall space utilization rate and integration of the battery pack 1.

[0057] In some examples, the first through hole 121 extends along the height direction of the first crossbeam 12 and forms a first opening 122 on the side of the first crossbeam 12 away from the bottom of the housing 10. By opening the first opening 122 on the first crossbeam 12, the first connecting strip 50 can be directly mounted on the first crossbeam 12 through the first opening 122 and pass through the first through hole 121, thereby helping to simplify the installation of the first connecting strip 50 and improve the overall production efficiency of the battery pack 1.

[0058] In some embodiments, please refer to Figure 1 and Figure 2 The battery pack 1 also includes a battery management module 40, which is located within the housing cavity 11. The battery management module 40 is electrically connected to the battery module 20 and the drive control module 30, thereby enabling the drive control module 30 to be electrically connected to the battery module 20. The battery management module 40 serves as the overall power output terminal of the battery pack 1, used for connection to external electrical equipment. By utilizing the battery management module 40 to achieve the electrical connection between the drive control module 30 and the battery module 20, compared to directly connecting the drive control module 30 to the battery module 20, all power output from the battery module 20 can be achieved through the battery management module 40, further improving the integration of the battery pack 1. This also helps improve the stability of power output between the battery module 20 and the drive control module 30, thereby ensuring the stability of the drive control module 30's control over the power module 2.

[0059] In some embodiments, please refer to Figure 4 and Figure 5 The battery pack 1 also includes a second connecting strip 60, which is used to connect the drive control module 30 and the battery management module 40. By using the second connecting strip 60 to connect the drive control module 30 and the battery management module 40, compared with the use of wire harness connection, the use of wire harness protection and support structure can be reduced, thereby helping to reduce the space occupation and reduce production costs. At the same time, it also helps to improve the internal orderliness of the battery pack 1 and reduce the risk of mutual interference.

[0060] In some embodiments, the receiving cavity 11 includes a first sub-receiving cavity 111 and a second sub-receiving cavity 112. The drive control module 30 is disposed in the first sub-receiving cavity 111, and the battery management module 40 is disposed in the second sub-receiving cavity 112. The housing 10 includes a second crossbeam 13, which is disposed between the first sub-receiving cavity 111 and the second sub-receiving cavity 112. That is, the drive control module 30 and the battery management module 40 can be separated by the second crossbeam 13 to reduce the risk of mutual interference between the drive control module 30 and the battery management module 40, thereby improving the overall stability of the battery pack 1.

[0061] In some examples, a second through hole 131 is provided on the second crossbeam 13, extending through the second crossbeam 13 along its thickness direction. The second through hole 131 is used for the second connecting row 60 to pass through, connecting the drive control module 30 and the battery management module 40. By providing a second through hole 131 on the second crossbeam 13 and arranging the second connecting row 60 to pass through the second through hole 131, the space utilization rate of the battery pack 1 in the height direction can be improved, thereby further improving the overall space utilization rate and integration of the battery pack 1.

[0062] In some examples, the second through hole 131 extends along the height direction of the second crossbeam 13, and a second opening 132 is formed on the side of the second crossbeam 13 away from the bottom of the housing 10. By opening the second opening 132 on the second crossbeam 13, the second connecting strip 60 can be directly mounted on the second crossbeam 13 through the second opening 132 and pass through the second through hole 131, thereby simplifying the installation of the second connecting strip 60 and improving the overall production efficiency of the battery pack 1.

[0063] In some embodiments, please refer to Figure 4 and Figure 5 The battery pack 1 also includes a third connecting strip 70, which is used to connect the battery management module 40 and the battery module 20. By using the third connecting strip 70 to connect the battery management module 40 and the battery module 20, compared with the use of wire harness connection, the use of wire harness protection and support structure can be reduced, thereby helping to reduce the space occupation and reduce production costs. At the same time, it also helps to improve the internal orderliness of the battery pack 1 and reduce the risk of mutual interference.

[0064] In some embodiments, the receiving cavity 11 includes a second sub-receiving cavity 112 and a third sub-receiving cavity 113. The battery management module 40 is disposed in the second sub-receiving cavity 112, and the battery module 20 is disposed in the third sub-receiving cavity 113. The housing 10 includes a third crossbeam 14, which is disposed between the second sub-receiving cavity 112 and the third sub-receiving cavity 113. That is, the battery module 20 and the battery management module 40 can be separated by the third crossbeam 14 to reduce the risk of mutual interference between the battery module 20 and the battery management module 40, thereby improving the overall stability of the battery pack 1.

[0065] In some examples, a third through hole 141 is provided on the third crossbeam 14, extending through the third crossbeam 14 along its thickness direction. The third through hole 141 is used for the passage of the third connecting row 70 to connect the battery module 20 and the battery management module 40. By providing a third through hole 141 on the third crossbeam 14 and arranging the third connecting row 70 to pass through the third through hole 141, the space utilization rate of the battery pack 1 in the height direction can be improved, thereby further improving the overall space utilization rate and integration of the battery pack 1.

[0066] In some examples, the third through hole 141 extends along the height direction of the third crossbeam 14, and a third opening 142 is formed on the side of the third crossbeam 14 away from the bottom of the housing 10. By opening the third opening 142 on the third crossbeam 14, the third connecting strip 70 can be directly mounted on the third crossbeam 14 through the third opening 142 and pass through the third through hole 141, thereby simplifying the installation of the third connecting strip 70 and improving the overall production efficiency of the battery pack 1.

[0067] In some examples, the receiving cavity 11 includes two third sub-receiving cavities 113, and a crossbeam structure is also provided between the two third sub-receiving cavities 113. The battery modules 20 in the two third sub-receiving cavities 113 can also be connected by a connecting row structure. Correspondingly, the connecting row structure can be mounted on the crossbeam structure to improve the space utilization rate of the battery pack 1 in the height direction, thereby improving the overall space utilization rate and integration of the battery pack 1.

[0068] The first sub-receiving cavity 111 can be located at the four corners of the third sub-receiving cavity 113, and the second sub-receiving cavity 112 is located on one side of the first sub-receiving cavity 111 along the length of the vehicle, so as to ensure the utilization rate of the internal space of the battery pack 1.

[0069] It should be noted that when two first sub-accommodating cavities 111, or the first sub-accommodating cavity 111 and the second sub-accommodating cavity 112, or the second sub-accommodating cavity 112 and the third sub-accommodating cavity 113 are spaced apart, that is, at least two crossbeam structures are provided between them, through holes and opening structures can be provided on each crossbeam structure to facilitate the corresponding connecting row structure to be mounted on the corresponding crossbeam structure, thereby realizing the electrical connection of the corresponding module.

[0070] In some embodiments, please refer to Figure 1 and Figure 2When the battery pack 1 is applied to a vehicle and the drive control module 30 is used to connect to the vehicle's power module 2, the power module 2 can be located on at least one side of the battery pack 1 along the length direction of the vehicle. Since the space between the battery pack 1 and the vehicle along the length direction is greater than the space between the battery pack 1 and the vehicle along the width direction, placing the power module 2 on at least one side of the battery pack 1 along the length direction of the vehicle is beneficial for the arrangement of the power module 2 and also helps to ensure the safety of the power module 2.

[0071] In some embodiments, the housing 10 includes two first side beams 15 arranged along the length direction of the vehicle. At least one first side beam 15 is provided with a connector 80, which is electrically connected to the drive control module 30 and is used for electrical connection with the power module 2. By using the connector 80 to connect the drive control module 30 and the power module 2, the connection method between the drive control module 30 and the power module 2 is simplified. Furthermore, by placing the connector 80 on the first side beam 15 arranged along the length direction of the vehicle, the safety of the connector 80 is ensured, thereby helping to ensure the connection stability between the drive control module 30 and the power module 2.

[0072] The box body 10 also includes two second side beams 16 arranged along the width direction of the vehicle. The two second side beams 16 are connected between the two first side beams 15, and the two second side beams 16 and the two first side beams 15 together enclose the receiving cavity 11 of the box body 10.

[0073] In some examples, the connector 80 is located on the side of the first side beam 15 away from the receiving cavity 11 to further ensure the safety of the connector 80, thereby ensuring the connection stability between the drive control module 30 and the power module 2.

[0074] In some examples, the first side beam 15 is also equipped with an AC charging / discharging interface, a cold plate flow channel inlet, and a DC charging / discharging interface to facilitate the connection design between the battery pack 1 and other external devices. By placing the connection port between the battery pack 1 and other external devices on the first side beam 15 arranged along the length of the vehicle, it is not only beneficial to connect the connection port to other external devices, but also helps to ensure the safety and stability of the connection port.

[0075] In some embodiments, the power module 2 is connected to the vehicle's wheels 3 and drives the wheels 3 to rotate. Specifically, the battery module 20 provides electrical energy to the drive control module 30, which controls the current and voltage input to the power module 2 to control its speed, torque, etc. The power module 2 then converts electrical energy into mechanical energy to drive the wheels 3 to rotate, thereby enabling the vehicle to turn or make a U-turn.

[0076] In some examples, the vehicle includes four power modules 2, and the battery pack 1 includes four drive control modules 30, with each drive control module 30 connected to a power module 2 in a one-to-one correspondence. That is, each power module 2 is connected to one wheel 3 of the vehicle and is controlled by a drive control module 30 to improve the stability of the drive control module 30's steering control of the wheel 3.

[0077] When the four drive control modules 30 are connected in parallel, the four power modules 2 can independently drive the corresponding wheels 3, so as to achieve separate control of the steering, speed and torque of the wheels 3, thereby making the control precision of the power modules 2 higher, so as to realize more steering strategies such as turning on the spot and reducing the turning radius, and improve the driving stability of the vehicle and reduce tail-swing accidents.

[0078] In some examples, the four drive control modules 30 are located at the four corners of the housing 11, and the four power modules 2 are located at the four corners outside the battery pack 1. That is, the distribution of the four drive control modules 30 and the four power modules 2 is consistent with the distribution of the four wheels 3 of the vehicle. This distribution allows the distance between the power modules 2 and the wheels 3 to be closer, thereby helping to reduce the size of the transmission structure between the power modules 2 and the wheels 3, and thus improving the transmission efficiency between the power modules 2 and the wheels 3.

[0079] Furthermore, by placing the four drive control modules 30 at the four corners of the receiving cavity 11 and the four power modules 2 at the four corners outside the battery pack 1, it is helpful to reduce the distance between the drive control module 30 and the power module 2, thereby helping to shorten the size of the connection structure between the drive control module 30 and the power module 2. This not only helps to save layout space but also reduces the overall production cost of the battery pack 1.

[0080] Correspondingly, when the four drive control modules 30 are respectively located at the four corners of the receiving cavity 11, and the four power modules 2 are respectively located at the four corners outside the battery pack 1, wireless communication can be used between the drive control modules 30 and the power modules 2. This arrangement reduces the distance between the drive control modules 30 and the power modules 2, thus minimizing the impact of external interference on their communication. This helps ensure the accuracy of the sampling signals between the drive control modules 30 and the power modules 2, as well as the implementation of wireless communication. Furthermore, wireless communication saves the space required for the support structure and wiring path of wire harness communication.

[0081] It should be noted that the power module 2 in this embodiment includes a wheel-side motor or a wheel hub motor. Since the arrangement of this type of motor is more flexible, it is beneficial to shorten the distance between the drive control module 30 and the power module 2, thereby helping to shorten the wireless communication between the drive control module 30 and the power module 2.

[0082] In some examples, the drive control module 30 and the power module 2 can also use wire harness communication to ensure the stability of communication between the drive control module 30 and the power module 2 and reduce the risk of communication interruption between the drive control module 30 and the power module 2.

[0083] It should be noted that the specific communication method between the drive control module 30 and the power module 2 can be designed and adjusted according to actual usage requirements. It is only necessary to ensure the accuracy and stability of the sampling signal between the drive control module 30 and the power module 2. No special restrictions are imposed here.
