[0002] Battery packs in related technologies typically include a battery pack and a battery control management system. The battery pack usually has a total positive or total negative output terminal and connects to the battery control management system via an adapter, facilitating monitoring of the battery pack by the system. However, because this adapter connects to the total positive or total negative terminal, it needs to carry the current of the entire battery pack and connect the partitioned battery pack and battery control management system. This necessitates a thicker adapter, resulting in a longer length and heavier weight. This can lead to excessive stress at the connection point between the adapter and the battery pack, resulting in poor connection reliability. Utility Model Content

[0049] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0050] In a first aspect, according to an embodiment of the present invention, a battery pack 1 is provided. The battery pack 1 has a first direction Z, a second direction X and a third direction Y that intersect each other in pairs. The battery pack 1 includes a first housing 100, a cover plate 110, a second housing 120, a battery pack 300, an electrical module 200, a first adapter 823, a second adapter 824 and a slave control module 500.

[0051] The cover plate 110 is connected to the first housing 100 along one side of the first direction Z, forming a first receiving cavity 101 with the first housing 100. The cover plate 110 is connected to the second housing 120 along the other side of the first direction Z, forming a second receiving cavity 102 with the second housing 120. The first receiving cavity 101 and the second receiving cavity 102 are stacked along the first direction Z. The first housing 100, the cover plate 110, and the second housing 120 are stacked along the first direction Z.

[0052] The battery pack 300 is located in the first receiving cavity 101, and the electrical module 200 is located in the second receiving cavity 102. That is to say, the battery pack 300 and the electrical module 200 are located on opposite sides of the cover plate 110 along the first direction Z.

[0053] The battery pack 300 includes multiple battery cells 301, which are electrically connected to each other. The battery pack 300 has a first output terminal 311 and a second output terminal 312 with opposite polarities. The first output terminal 311 and the second output terminal 312 are located on opposite sides of the first receiving cavity 101 along a third direction Y. That is, the first output terminal 311 can be a positive output terminal, and the second output terminal 312 can be a negative output terminal.

[0054] At least a portion of the first adapter 823 and the second adapter 824 are located within the first receiving cavity 101, and the first adapter 823 and the second adapter 824 are disposed on one side of the battery pack 300 along the second direction X. One end of the first adapter 823 is connected to the first output terminal 311, and the other end of the first adapter 823 is electrically connected to the electrical module 200. One end of the second adapter 824 is connected to the second output terminal 312, and the other end of the second adapter 824 is electrically connected to the electrical module 200.

[0055] The slave control module 500 is disposed in the first receiving cavity 101, and the slave control module 500, the first adapter 823 and the second adapter 824 are located on the same side of the battery pack 300 along the second direction X, that is, the slave control module 500 is located on the side of the battery pack 300 facing the first adapter 823 and the second adapter 824. The slave control module 500 is electrically connected to the electrical module 200. At least a portion of the first adapter 823 and at least a portion of the second adapter 824 are disposed on the side of the slave control module 500 facing the cover plate 110 along the first direction Z.

[0056] Multiple battery cells 301 can be connected in series or parallel. The battery control management system typically includes a battery management system (BMS) and a battery distribution unit (BDU). The SYSTEM (BMS) can be divided into a main control module and a slave control module as needed. In this embodiment, the electrical module 200 may include the main control module of the battery management system and the battery distribution unit. The slave control module 500 may refer to the slave control module of the battery management system. The main control module of the battery management system is electrically connected to the slave control module 500. The slave control module 500 is used to collect the working data of at least one battery cell 301. The battery management system manages and maintains multiple battery cells 301 according to the feedback results from the slave control module 500, prevents the battery cells 301 from overcharging and over-discharging, extends the service life of the battery cells 301, and monitors the status of the battery cells 301. The main control module of the battery management system is connected to the battery distribution unit. The battery distribution unit is connected to the first output terminal 311 and the second output terminal 312. The battery distribution unit is used to connect to the high-voltage load of the vehicle and the fast charging harness through the high-voltage electrical interface to realize the distribution and management of the energy of the battery cells 301.

[0057] Of course, electrical module 200 may also include only the battery power distribution unit, and slave module 500 may refer to the battery management system, wherein the battery power distribution unit is electrically connected to slave module 500.

[0058] By layering the first receiving cavity 101 and the second receiving cavity 102, i.e., stacking the first receiving cavity 101 and the second receiving cavity 102, and separating the first receiving cavity 101 and the second receiving cavity 102 by the cover plate 110, the number of electrical components in the first receiving cavity 101 can be reduced, the number of battery cells 301 that can be arranged in the first receiving cavity 101 can be increased, thereby achieving the purpose of increasing the capacity of the battery pack 1.

[0059] In addition, the first receiving cavity 101 can be filled with expanding foam to improve the strength of the battery pack 1. By setting the first receiving cavity 101 and the second receiving cavity 102 in layers, the electrical module 200 can be prevented from being affected by the expanding foam, and the electrical components in the second receiving cavity 102 can be adjusted and repaired in the future, thereby reducing the cost of using the battery pack 1.

[0060] By setting up the slave control module 500, it can not only acquire data information from the battery pack 300, but also support the adapter. The slave control module 500 bears at least a portion of the weight of the first adapter 823 and the second adapter 824, which can reduce the probability of separation between the adapter and the output terminal, improve the connection reliability between the adapter and the output terminal, prevent the welding of the adapter and the battery pack 300 from falling off due to stress, thus ensuring the stability of its electrical connection and ensuring the normal operation of the battery pack 1.

[0061] Furthermore, since the slave control module 500 supports the first adapter 823 and the second adapter 824, the installation stability of the first adapter 823 and the second adapter 824 is increased. Therefore, the lengths of the first adapter 823 and the second adapter 824 can be set to be longer to facilitate the connection of the internal circuits of the battery pack 1. Moreover, the slave control module 500, at least a portion of the first adapter 823, and at least a portion of the second adapter 824 are stacked along the first direction Z, which can effectively utilize the space of the first receiving cavity 101 along the first direction Z, save space in other positions of the first receiving cavity 101, improve the space utilization rate within the first receiving cavity 101, and increase the capacity of the battery pack 1 by arranging more battery cells 301.

[0062] Since the first output terminal 311 and the second output terminal 312 are located on opposite sides of the first receiving cavity 101 along the third direction Y, this can increase the distance between the first output terminal 311 and the second output terminal 312, reducing the probability of short circuit in the battery pack 1, and leave a middle area for installing the slave control module 500, making full use of the space of the first receiving cavity 101 along the third direction Y and improving space utilization.

[0063] For example, insulating foam can be provided between the slave control module 500 and the adapter. On the one hand, it can provide buffer support for the adapter, and on the other hand, it can protect the slave control module 500 from electromagnetic interference and improve the reliability of data acquisition.

[0064] like Figure 4 , Figure 5 and Figure 7 As shown, in the technical solution of this embodiment, the battery pack 1 further includes an information acquisition component 600. The information acquisition component 600 is located in the first receiving cavity 101 and is disposed between the battery pack 300 and the cover plate 110. The information acquisition component 600 extends along the second direction X. The information acquisition component 600 includes an acquisition end (not shown in the figure) and a plug-in end 610. The acquisition end and the plug-in end 610 are electrically connected. The control module 500 has a plug-in interface 510 on the side facing the battery pack 300. The acquisition end is connected to at least one of the multiple battery cells 301, and the plug-in end 610 is plugged into the plug-in interface 510.

[0065] The acquisition terminal is used to acquire at least one of the following information: voltage, current, and temperature of the battery cell 301.

[0066] In this way, while enabling the information acquisition component 600 to acquire data from the battery pack 300, interference between the plug-in terminal 610 and the adapter can be avoided, making the layout more convenient, making full use of the surface space of the slave control module 500, and improving the compactness of the layout.

[0067] like Figures 5-8 As shown, in this embodiment, the battery pack 1 further includes a pressure plate 700. The pressure plate 700 is located within the first receiving cavity 101, and at least a portion of the pressure plate 700 is located along the first direction Z on the side of the plug-in terminal 610 facing the cover plate 110. The pressure plate 700 is connected to the side of the slave control module 500 along the second direction X facing the battery pack 300. At least a portion of the pressure plate 700 is located along the first direction Z between the plug-in terminal 610 and the cover plate 110. The pressure plate 700 can be made of insulating material to prevent electrical connection between the pressure plate 700 and the plug-in terminal 610.

[0068] By setting the pressure plate 700, the position of the plug-in end 610 can be limited, reducing the probability of the plug-in end 610 of the information acquisition component 600 shaking. On the one hand, this ensures the reliability of the connection between the slave control module 500 and the information acquisition component 600, and on the other hand, it avoids interference between the information acquisition component 600 and other structures, thereby improving the reliability of the battery pack 1.

[0069] Furthermore, in the technical solution of this embodiment, the pressure plate 700 has a pressure strip 720 extending along a third direction Y. The pressure strip 720 is provided with a widening section 710. The dimension of the widening section 710 along the second direction X is larger than the dimension of the other positions of the pressure strip 720 along the second direction X. The widening section 710 is correspondingly arranged with the plug-in interface 510 along the second direction X, that is, the widening section 710 is correspondingly arranged with the plug-in end 610 along the second direction X. The battery pack 1 may have multiple information acquisition components 600, and the number of widening sections 710 may be multiple, with multiple widening sections 710 corresponding one-to-one with multiple plug-in ends 610.

[0070] By setting the widening section 710, the contact area between the pressure plate 700 and the plug-in end 610 can be increased, the limiting effect of the pressure plate 700 on the plug-in end 610 can be improved, and the probability of the plug-in end 610 of the information acquisition component 600 shaking can be further reduced.

[0071] For example, the control module 500 has two mounting members 530 on the side facing the battery pack 300 along the second direction X. The pressure plate 700 includes two mounting feet 730, which are connected to the opposite sides of the pressure strip 720. The two mounting feet 730 correspond to the two mounting members 530. The mounting feet 730 are located on the side of the mounting member 530 facing the cover plate 110 along the first direction Z. The mounting feet 730 are away from the cover plate 110 relative to the pressure strip 720 along the first direction Z to ensure that the pressure strip 720 limits the insertion end 610.

[0072] like Figure 6 and Figure 9 As shown, in the technical solution of this embodiment, the first box 100 includes a frame 130 and a bottom support plate 140. The cover plate 110 and the bottom support plate 140 are respectively covered on the two sides of the frame 130 opposite to each other along the first direction Z, and the cover plate 110, the frame 130 and the bottom support plate 140 together enclose the first receiving cavity 101.

[0073] The frame 130 includes a front beam 131, which is located in front of the battery pack 300. The battery pack 300 and the front beam 131 are spaced apart. The front beam 131 is located at one end of the frame 130 along the second direction X and extends along the third direction Y. The front beam 131 and the slave control module 500 are located on the same side of the battery pack 300 along the second direction X.

[0074] The first output terminal 311 and the second output terminal 312 are disposed close to the front beam 131 along the second direction X, and the slave control module 500 is installed on the side of the front beam 131 facing the battery pack 300 along the second direction X, that is, the slave control module 500 is installed between the front beam 131 and the battery pack 300. The slave control module 500 extends along the third direction Y. At least a portion of the first adapter 823 and at least a portion of the second adapter 824 extend along the third direction Y and are located on the side of the slave control module 500 facing the cover plate 110 along the first direction Z.

[0075] The slave control module 500 can be inserted between the battery pack 300 and the front beam 131 along the first direction Z. That is, the size of the slave control module 500 along the first direction Z is larger than that along the second direction X. The space occupied by the slave control module 500 in the first receiving cavity 101 along the second direction X is smaller.

[0076] In this way, the space of the first receiving cavity 101 can be fully utilized, and it is easy to realize that the slave control module 500 is located between the battery pack 300 and the front beam 131, and the slave control module 500 is connected to the frame 130, so that the installation is stable.

[0077] like Figures 8-9As shown, in this embodiment, the front beam 131 has a boss 132 on the side facing the battery pack 300 along the second direction X, and the control module 500 has a positioning rib 520 on the side facing away from the battery pack 300 along the second direction X. The positioning rib 520 is installed on the side of the boss 132 facing the cover plate 110 in the first direction Z. Bolts can pass through the positioning rib 520 and be threaded to the boss 132.

[0078] By setting the boss 132, the space between the front beam 131 and the battery pack 300 is fully utilized, and the boss 132 can support the slave control module 500 along the first direction Z, which helps to reduce the risk of damage to the connection between the slave control module 500 and the boss 132 under stress and improves the installation reliability of the slave control module 500.

[0079] like Figure 3 , Figure 6 and Figure 10 As shown, in the technical solution of this embodiment, the cover plate 110 has an opening 111 extending along a first direction, and the first receiving cavity 101 and the second receiving cavity 102 are connected through the opening 111. The battery pack 1 also includes an insulating base 810, which is disposed in the first receiving cavity 101. The insulating base 810, the slave control module 500, the first adapter 823, and the second adapter 824 are disposed on the same side of the battery pack 300 along the second direction X. The insulating base 810 is disposed along the first direction Z on the side of the slave control module 500 facing the cover plate 110. The insulating base 810 is disposed at the opening 111 and is located between the first output terminal 311 and the second output terminal 312. The first adapter 823... 3. The second adapter 824 extends along the third direction Y. One end of the first adapter 823 along the third direction Y is connected to the first output terminal 311. One end of the second adapter 824 along the third direction Y is connected to the second output terminal 312. The other end of the first adapter 823 and the other end of the second adapter 824 are connected to the insulating base 810. That is, the first adapter 823 and the second adapter 824 extend along the third direction Y towards the insulating base 810 and pass through the insulating base 810 and are connected to the electrical module 200.

[0080] For example, after the first adapter 823 and the second adapter 824 extend to the insulating base 810, they can be bent in the first direction Z toward the cover plate 110 to achieve electrical connection between the first adapter 823 and the second adapter 824 and the electrical module 200.

[0081] The insulating base 810 can support the ends of the first adapter 823 and the second adapter 824. That is, the insulating base 810 and the slave control module 500 jointly support the first adapter 823 and the second adapter 824. Most of the weight of the first adapter 823 and the second adapter 824 can be borne by the insulating base 810 and the slave control module 500, which can more effectively fix the first adapter 823 and the second adapter 824, ensure the positional reliability of the first adapter 823 and the second adapter 824, reduce the probability of the adapter and the output terminal separating, and improve the circuit reliability of the battery pack 1.

[0082] like Figure 6 and Figure 11 As shown, in the technical solution of this embodiment, the side of the frame 130 facing the battery pack 300 is provided with a first support base 150 and a second support base 160. The connection between the first output end 311 and the first adapter 823 is supported on the first support base 150, and the connection between the second output end 312 and the second adapter 824 is supported on the second support base 160.

[0083] By setting the first support base 150 and the second support base 160, the connection between the first output terminal 311 and the first adapter 823, as well as the connection between the second output terminal 312 and the second adapter 824, can be supported, avoiding excessive force on the connection between the output terminal and the adapter, reducing the probability of separation between the output terminal and the adapter, improving the stability of the relative position of the output terminal and the adapter, and thus improving the working reliability of the battery pack 1.

[0084] Since the first support 150 supports the end of the first adapter 823 and the second support 160 supports the end of the second adapter 824, the stability of the first adapter 823 and the second adapter 824 is increased. Therefore, the lengths of the first adapter 823 and the second adapter 824 can be set to be longer to facilitate the connection of the internal circuit of the battery pack 1.

[0085] In the technical solution of this embodiment, an insulating layer 825 is covered between the two ends of the first adapter 823, that is, the outer peripheral surface of the first adapter 823 is provided with an insulating layer 825, the first adapter 823 extends the insulating layer 825 at both ends along the third direction Y, one end of the first adapter 823 extending out of the insulating layer 825 is connected to the first output terminal 311, and the other end of the first adapter 823 extending out of the insulating layer 825 is electrically connected to the electrical module 200.

[0086] An insulating layer 825 is wrapped between the two ends of the second adapter 824, that is, the outer peripheral surface of the second adapter 824 is provided with an insulating layer 825. The insulating layer 825 extends out of both ends of the second adapter 824 along the third direction Y. One end of the second adapter 824 extending out of the insulating layer 825 is connected to the second output terminal 312, and the other end of the second adapter 824 extending out of the insulating layer 825 is electrically connected to the electrical module 200.

[0087] The insulating layer 825 can be formed by means of heat shrink tubing or insulating material coating.

[0088] In this way, the adapter is only electrically connected to the output terminal and the electrical module 200, which can prevent the adapter from being electrically connected to other electrical structures in the battery pack 1, thereby improving the electrical safety of the battery pack 1.

[0089] Secondly, according to an embodiment of the present invention, an electrical device is provided, which includes the aforementioned battery pack 1. The electrical device can be a vehicle or an energy storage device.

[0090] The electrical equipment of this utility model, through the battery pack 1, can utilize the slave control module 500 to support the first adapter 823 and the second adapter 824, thereby improving the connection reliability between the first adapter 823 and the first output terminal 311, and improving the connection reliability between the second adapter 824 and the second output terminal 312.

[0091] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
