For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0054] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0055] In the embodiments of the present application, the term “electrically connected” may refer to a direct electrical connection between two components, or may refer to an electrical connection between two components via one or more other components.

[0056] It will be apparent to those skilled in the art that various modifications and variations can be made in this application without departing from the spirit or scope of this application. Therefore, this application is intended to cover modifications and variations of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the examples of this application can be combined with each other without contradiction.

[0057] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the related art:

[0058] As the power supply component of electric vehicles, batteries play a decisive role in the vehicle's range, cost, and lifespan. However, the current integration of internal circuits in batteries is low, resulting in high costs.

[0059] With the development of technology, vehicle battery swapping has become a key area of ​​battery technology development. For example, in a battery swapping application, the battery (or battery pack) of a vehicle entering a battery swap station can be removed and then replaced with the battery from the station. Therefore, the battery can also be called a battery swap cabinet or battery swap box.

[0060] Figure 1 is a structural diagram of a battery in the related art. As shown in Figure 1, in the related art, a battery box 110', a junction box 120' and a control box 130' may be provided in the battery (or battery exchange cabinet) 10'. The battery box 110' may be provided with a battery. The junction box 120' may be provided with a busbar ML' and a voltage sampling module 121'. Exemplarily, the voltage sampling module 121' may include a high voltage sampling board (High Voltage Board, HVB). ​​The busbar ML' in the junction box 120' may be electrically connected to the battery box 110'. In addition, a relay may be provided in the junction box 120', and the relay is connected to the busbar ML'. For the sake of simplicity, the relay is not shown in Figure 1. The control box 130' may be provided with a battery management unit (Battery management Unit, BMU) 131'. The junction box 120' and the control box 130' may be connected by a connector 140'.

[0061] As can be seen, the battery 10' in the related art is equipped not only with a junction box 120' but also with a control box 130'. The busbar ML' and voltage sampling module 121' are located in the junction box 120', while the battery management unit 131' is located in the control box 130'. This results in a low level of integration within the battery 10''s internal circuitry, requiring more and / or longer wiring harnesses, resulting in higher wiring harness costs. Furthermore, communication between the junction box 120' and the control box 130' requires a connector 140', increasing connector costs and the risk of communication failure.

[0062] In view of the above research findings of the inventors, the embodiments of the present application provide a battery, a vehicle-mounted connection device, a topology architecture and an electrical device, which can solve at least one of the above technical problems existing in the related art.

[0063] The technical concept of the embodiment of the present application is as follows: on the one hand, the busbar, the first battery management unit and the first voltage sampling module are all integrated into the first shell of the first control component, which is conducive to reducing the length of the wiring harness between the first voltage sampling module and the first battery management unit, and / or reducing the length of the wiring harness between the first voltage sampling module and the busbar, thereby reducing the wiring harness cost; on the other hand, since the first battery management unit and the first voltage sampling module are all integrated into the first shell of the first control component, the connector between the first voltage sampling module and the first battery management unit can be reduced, saving the cost of using connectors, and at the same time helping to reduce the risk of communication failure. On the other hand, by improving the integration of the first control component in the battery, that is, improving the integration of the battery, it is conducive to reducing the volume and occupied space of the battery.

[0064] The following first introduces the battery provided in the embodiments of the present application.

[0065] FIG2 is a schematic diagram of the structure of a battery provided in an embodiment of the present application. As shown in FIG2 , the battery 100 provided in an embodiment of the present application may include a battery module 10 and a first control component 20, and the first control component 20 may be electrically connected to the battery module 10. The battery 100 may also be referred to as a battery pack. The battery 100 may include one or more battery modules 10. The number of battery modules 10 may be flexibly adjusted according to actual conditions, and the present application does not limit this. A battery module 10 may include multiple single cells connected in series, in parallel, or in mixed connection. Mixed connection refers to multiple single cells connected in series and in parallel. The first control component 20 may include a first shell 201, a busbar ML, a first battery management unit 202, and a first voltage sampling module 203. The first battery management unit 202 may be referred to as a slave battery management unit, or SBMU for short. The first battery management unit 202 can be used to manage the first control component, such as receiving data such as battery voltage, current and / or temperature, calculating the battery state of charge (SOC) and battery state of health (SOH), and completing battery pre-charging and charge and discharge management.

[0066] The busbar ML, the first battery management unit 202 and the first voltage sampling module 203 may be located inside the first housing 201 , that is, inside a cavity (or space) formed by the first housing 201 .

[0067] The first voltage sampling module 203 can be electrically connected to the bus ML and the first battery management unit 202. The first voltage sampling module 203 can be mainly used to collect the voltage of the bus ML and perform insulation testing. The first voltage sampling module 203 can include a high voltage sampling board (HVB).

[0068] In the battery provided by the embodiment of the present application, on the one hand, the busbar, the first battery management unit, and the first voltage sampling module are all integrated into the first housing of the first control component, which is conducive to reducing the length of the wiring harness between the first voltage sampling module and the first battery management unit, and / or reducing the length of the wiring harness between the first voltage sampling module and the busbar, thereby reducing the wiring harness cost; on the other hand, since the first battery management unit and the first voltage sampling module are both integrated into the first housing of the first control component, the connector between the first voltage sampling module and the first battery management unit can be reduced, saving the cost of using connectors and helping to reduce the risk of communication failure. On the other hand, by improving the integration of the first control component in the battery, that is, improving the integration of the battery, it is conducive to reducing the volume and occupied space of the first control component.

[0069] 1 , in the related art, the busbar ML' of the junction box 120' and the conversion connector 150' need to be connected via a high-voltage line GL', which further increases the cost of the wiring harness.

[0070] Figure 3 is another structural schematic diagram of the battery provided in an embodiment of the present application. As shown in Figure 3, according to some embodiments of the present application, optionally, the battery module 10 can be electrically connected to the busbar ML. The first control component 20 can also include a first connector 301. The first control component 20 can be electrically connected to other devices (such as charging equipment or the vehicle-mounted connection device below) through the first connector 301. Each first control component 20 can have only one first connector 301, based on which charging at the battery swap station and discharging outside the station can be performed. The busbar ML and the first battery management unit 202 can be electrically connected to the first connector 301.

[0071] In some examples, the first connector 301 may include a quick-change connector.

[0072] As shown in Figure 3, according to some embodiments of the present application, a first connector 301 may optionally be provided on the first housing 201. This application does not limit the connection method between the first connector 301 and the first housing 201. For example, the first connector 301 may be fixedly connected to the first housing 201 or detachably connected. In other words, the first connector 301 may also be integrated into the first housing 201.

[0073] In this way, the busbar ML can be directly connected to the first connector 301 , thereby reducing the high-voltage line GL′ between the busbar ML′ and the conversion connector 150 ′ shown in FIG. 1 , thereby further reducing the cost of the first control assembly 20 .

[0074] As shown in Figure 3, according to some embodiments of the present application, optionally, at least one side of the first shell 201 of the first control component 20 (such as the side where the first connector 301 is located) can be connected to the shell K of the battery 100 to facilitate the electrical connection of the first connector 301 with other devices (such as a charging device or the vehicle-mounted connection device mentioned below).

[0075] As shown in FIG3 , according to some embodiments of the present application, optionally, the first connector 301 may include a main circuit interface ZJ, a low voltage interface DJ, and a ground interface PE.

[0076] The main circuit interface ZJ can be electrically connected to the busbar ML, the low-voltage interface DJ can be electrically connected to the first battery management unit 202, and the ground interface PE can be electrically connected to the ground terminal GND. For example, the ground terminal GND includes, but is not limited to, the vehicle ground or the charger ground in the battery swap station. In some examples, the main circuit interface ZJ and the low-voltage interface DJ can each include one or more interfaces, which is not limited in this application.

[0077] Figure 4 is a circuit diagram of a battery provided in an embodiment of the present application. As shown in Figure 4, according to some embodiments of the present application, optionally, the low-voltage interface DJ may include a communication interface 41. The communication interface 41 may be electrically connected to the first battery management unit 202. The first battery management unit 202 can communicate with other devices through the communication interface 41 of the first connector 301. The present application does not limit the type of the communication interface 41. For example, in some examples, the communication interface 41 may include a controller area network bus (CAN) communication interface, such as a CAN_H communication interface and a CAN_L communication interface. The first connector 301 may include one or more communication interfaces 41. The number of communication interfaces 41 can be flexibly adjusted according to actual conditions, and the present application does not limit this.

[0078] As shown in FIG4 , according to some embodiments of the present application, the low-voltage interface DJ may optionally include a first connector connection state detection interface 42. The first connector connection state detection interface 42 may be electrically connected to the first battery management unit 202. The first battery management unit 202 may detect the connection state of the first connector 301 through the first connector connection state detection interface 42.

[0079] For example, in some examples, the first connector connection status detection interface 42 may include a connection status detection input interface 421 and a connection status detection output interface 422. The connection status detection input interface 421 and the connection status detection output interface 422 can be electrically connected to the first battery management unit 202. The first battery management unit 202 can provide a voltage signal of a first preset voltage value to the connection status detection input interface 421, and receive a voltage signal fed back by the connection status detection output interface 422. When the voltage value of the voltage signal fed back by the connection status detection output interface 422 is within a preset voltage range, it is determined that the first connector 301 is connected to other devices. When the voltage value of the voltage signal fed back by the connection status detection output interface 422 is not within the preset voltage range, it is determined that the first connector 301 is not connected to other devices. The first preset voltage value and the preset voltage range can be flexibly adjusted according to actual conditions, and this application does not limit this.

[0080] As shown in Figure 4, according to some embodiments of the present application, optionally, the low-voltage interface DJ may include a first connector temperature status detection interface 43. The first connector temperature status detection interface 43 may be electrically connected to the first battery management unit 202. The first battery management unit 202 may detect the temperature status of the first connector 301 through the first connector temperature status detection interface 43. For example, the first battery management unit 202 may receive a signal reflecting the temperature of the first connector fed back by the first connector temperature status detection interface 43, and by processing the signal, the temperature of the first connector 301 may be obtained. In some examples, when the temperature of the first connector 301 is greater than a preset temperature threshold, an overtemperature warning may be issued. The preset temperature threshold may be flexibly adjusted according to actual conditions, and this application does not limit this.

[0081] As shown in Figure 4, according to some embodiments of the present application, optionally, the low-voltage interface DJ may include a position identification signal interface 44, and the position identification signal interface 44 may be electrically connected to the first battery management unit 202. The first battery management unit 202 can determine the location of the battery 100 or the vehicle where the battery 100 is located through the position identification signal interface 44. For example, in some examples, when the first battery management unit 202 detects that the position identification signal interface 44 feedback is a first level, it can be determined that the battery 100 or the vehicle where the battery 100 is located is in a battery swap station. When the first battery management unit 202 detects that the position identification signal interface 44 feedback is a second level, it can be determined that the battery 100 or the vehicle where the battery 100 is located is not in a battery swap station, that is, outside the battery swap station. Exemplarily, the first level may include a high level, and the second level may include a low level.

[0082] It should be noted that Figure 4 shows the low-voltage interface DJ as an example, which includes a communication interface 41, a first connector connection status detection interface 42, a first connector temperature status detection interface 43 and a position identification signal interface 44. In other embodiments, the low-voltage interface DJ may also include any one or more of the communication interface 41, the first connector connection status detection interface 42, the first connector temperature status detection interface 43 and the position identification signal interface 44.

As shown in FIG5 , according to some embodiments of the present application, the first control component 20 may optionally further include an adapter connector 51. The first battery management unit 202 may be electrically connected to the first connector 301 via the adapter connector 51.

[0084] As shown in FIG5 , in some specific embodiments, the adapter connector 51 may optionally include a first adapter connector 511 and a second adapter connector 512, and the first adapter connector 511 may be electrically connected to the second adapter connector 512. The first adapter connector 511 and the second adapter connector 512 may each include multiple interfaces. The multiple interfaces of the first adapter connector 511 may be electrically connected to the multiple interfaces of the second adapter connector 512 in a one-to-one correspondence.

[0085] In some embodiments, the first adapter connector 511 and the second adapter connector 512 can be compatible. For example, in some examples, the first adapter connector 511 can be a male connector, and the second adapter connector 512 can be a female connector. In other examples, the first adapter connector 511 can be a female connector, and the second adapter connector 512 can be a male connector.

[0090] In this way, the first control assembly 20 can be connected to the cloud platform through the first networking module 52. Furthermore, since the first networking module 52 is integrated into the first housing 201, the wiring harness length between the first networking module 52 and the first battery management unit 202 is reduced, thereby lowering wiring harness costs. Furthermore, the space within the first housing 201 can be fully utilized to install the first networking module 52, which helps reduce the volume and space occupied by the first control assembly, and thus the volume and space occupied by the battery.

[0094] In this way, the positioning module 53 can be used to locate the battery 100. Furthermore, since the positioning module 53 is integrated into the first housing 201, the length of the wiring harness between the positioning module 53 and the first battery management unit 202 is reduced, thereby reducing wiring harness costs. Furthermore, the space within the first housing 201 can be fully utilized to install the positioning module 53, which helps reduce the volume and space occupied by the first control assembly, thereby reducing the volume and space occupied by the battery.
