[0057] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0058] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0060] In the description of the embodiments of the present application, the term "plurality" refers to more than two (including two).

[0061] In the description of the embodiments of the present application, the orientations or positional relationships indicated by technical terms such as "up", "down", "front", "back", "left", "right", "horizontal", "bottom", "inside", and "outside" are based on the orientations or positional relationships shown in the accompanying drawings.

Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0062] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0063] Currently, market developments indicate that power batteries are becoming increasingly widespread. They are used not only in energy storage systems such as hydropower, thermal, wind, and solar power plants, but also in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing. Lithium-ion batteries are increasingly accounting for a larger share of the power batteries currently in use.

[0064] The heat exchange components in the battery are usually cold plate structures, cold pipe structures, etc. After the heat exchange components are arranged in the battery box, the positions of the water inlet and outlet structures of the heat exchange components remain fixed. The joint structure in the battery used to connect with the external liquid supply equipment and the water inlet and outlet of the heat exchange component is greatly restricted by the position of the water inlet and outlet structure when arranged on the battery. The arrangement position is relatively fixed and the arrangement flexibility is poor. When the battery is used in different electrical devices, the position of the interface structure of the external liquid supply equipment is different, which makes it difficult to flexibly adjust the joint structure according to different interface structures.

[0065] In a battery, when the space at the water inlet and outlet structure of the heat exchange component is relatively narrow and cramped, since the joint structure is usually installed on the side wall of the battery box, the water inlet and outlet structure and the joint structure are in different horizontal planes, and there is a certain distance between the water inlet and outlet structure and the joint structure, making it inconvenient to connect the water inlet and outlet structure and the joint structure.

[0066] Based on the above considerations, the present application proposes a battery, which is equipped with an adapter, which is connected to the heat exchange component and the liquid inlet joint and liquid outlet joint, so that the liquid inlet joint and liquid outlet joint can be conveniently connected to the heat exchange component through the adapter.

[0067] The batteries disclosed in the embodiments of the present application can be used as power sources for electrical devices, or in various energy storage systems that use batteries as energy storage elements. The electrical devices may include, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, battery-powered vehicles, electric vehicles, ships, spacecraft, and the like. Electric toys may include fixed or mobile electric toys, such as game consoles, electric vehicle toys, electric ship toys, and electric airplane toys, and spacecraft may include airplanes, rockets, space shuttles, and spacecraft, among others.

[0068] refer to Figure 1 As shown, Figure 1 In a specific embodiment of the present application, the power consumption device 1000 is a schematic diagram of a vehicle. The vehicle can be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle. The battery 100 can be provided at the bottom, head, or tail of the vehicle. The battery 100 can be used to power the vehicle. For example, the battery 100 can serve as the operating power source of the vehicle. The vehicle can also include a controller 300 and a motor 200. The controller 300 is used to control the battery 100 to power the motor 200, for example, to meet the power requirements of the vehicle during startup, navigation, and driving.

[0069] In some embodiments of the present application, the battery 100 can serve not only as the operating power source of the vehicle, but also as the driving power source of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0071] Figure 9 is an exploded view of a battery 100 according to an embodiment of the present application; Figure 101 is a schematic diagram of a battery 100 according to an embodiment of the present application without the adapter 30 , the liquid inlet connector 40 , and the liquid outlet connector 50 ; Figure 11 FIG. 1 is an exploded view of the battery 100 according to an embodiment of the present application from another angle.

[0072] like Figure 2 and Figure 7 As shown, the battery 100 according to the embodiment of the first aspect of the present application includes: a box body 10, a heat exchange component 20, an adapter 30, a liquid inlet connector 40 and a liquid outlet connector 50.

[0073] Specifically, the box body 10 has a receiving cavity 101, and the box body 10 includes an expansion beam 122. The expansion beam 122 is arranged in the receiving cavity 101 and extends along a first direction (such as Figure 7 The heat exchange assembly 20 is provided in the accommodating cavity 101 and is arranged in the expansion beam 122 in the second direction (as shown in the left and right directions); Figure 7 On one side of the front-to-back direction shown in the figure, the heat exchange component 20 has a liquid inlet and a liquid outlet, and the second direction intersects with the first direction; the adapter 30 is arranged in the accommodating cavity 101 and is arranged on the other side of the expansion beam 122 in the second direction, the adapter 30 has a first flow cavity and a second flow cavity that are not connected to each other, the first flow cavity is connected to the liquid inlet, and the second flow cavity is connected to the liquid outlet; one end of the liquid inlet joint 40 is connected to the adapter 30 and is connected to the first flow cavity, and the other end of the liquid inlet joint 40 extends out of the outside of the box body 10, one end of the liquid outlet joint 50 is connected to the adapter 30 and is connected to the second flow cavity, and the other end of the liquid outlet joint 50 extends out of the outside of the box body 10.

[0074] In this embodiment, the housing 10 may be a hollow structure, and the hollow structure of the housing 10 forms a housing cavity 101 of the housing 10. The housing 10 may provide a housing space for the expansion beam 122, the heat exchange assembly 20, etc. The housing 10 may adopt a variety of structures. For example, the housing 10 may include a first part and a second part, the first part and the second part covering each other, and the first part and the second part may jointly define the housing cavity 101, wherein the first part may be a plate-like structure, and the second part may be a hollow structure with one side open, and the first part covers the open side of the second part. The first part and the second part may also be hollow structures with one side open, and the open side of the first part covers the open side of the second part, thereby jointly defining the housing cavity 101. The second part may also be an annular structure, and the first part covers the opening on one side of the second part. The opening on the other side of the second part may be sealed by other sealing structures. For example, the opening on the other side of the second part may be covered and sealed by a sealing plate, etc., to form a sealed housing cavity 101 space with the housing 10.

[0075] The shape of the box body 10 can be reasonably set as needed. For example, the box body 10 can be a rectangular parallelepiped, a cylinder, etc.

[0076] The box body 10 is provided with an expansion beam 122, which can be made of aluminum, steel, aluminum alloy or composite materials. The expansion beam 122 extends along the first direction and divides the accommodating cavity 101 into two parts in the second direction. The expansion beam 122 is arranged with a heat exchange component 20 on one side of the second direction, and an adapter 30 is arranged on the other side of the expansion beam 122 in the second direction.

[0077] The heat exchange assembly 20 may include a cold plate structure, a cold pipe structure, a flow channel plate structure, etc. The heat exchange assembly 20 may also include other structures, such as a current collecting structure. The heat exchange assembly 20 is used to exchange heat with the battery assembly of the battery 100. The battery assembly and the heat exchange assembly 20 are arranged on the same side of the expansion beam 122. The battery assembly may include multiple battery cells. Specifically, the multiple battery cells may be stacked along the second direction so that the expansion beam 122 can inhibit the expansion of the multiple battery cells in the battery assembly.

[0078] In this embodiment, the second direction intersects the first direction, where the intersection is intended to illustrate that the first direction and the second direction may be perpendicular to each other or form an acute angle or an obtuse angle. Specifically, the second direction and the second direction are both in a horizontal plane.

[0079] The adapter 30 can be made of aluminum, steel, plastic or composite materials. The first flow cavity and the second flow cavity in the adapter 30 can be extended in any direction and arranged in the adapter 30 as needed. The first flow cavity is connected between the liquid inlet and the liquid inlet connector 40, and the second flow cavity is connected between the liquid outlet and the liquid outlet connector 50.

[0080] The liquid inlet connector 40 is connected to the liquid infusion line of the external liquid supply device, and the liquid outlet connector 50 is connected to the liquid return line of the external liquid supply device. During the operation of the battery 100, the coolant flows into the first circulation cavity along the liquid infusion line and the liquid inlet connector 40, and then flows along the first circulation cavity from the liquid inlet into the heat exchange pipeline, so that the heat exchange pipeline and the battery assembly perform heat exchange operations. The coolant after heat exchange flows from the liquid outlet into the second circulation cavity, and then flows along the second circulation cavity and the liquid outlet connector 50 to the liquid return line, thereby completing the circulation of the coolant.

[0081] It can be understood that in different electrical devices 1000, the layout of the infusion pipeline and the return pipeline of the liquid supply equipment is different, and the relative positions of the liquid inlet and the liquid outlet in the battery 100 after layout are also different. In this embodiment, an adapter 30 is set between the heat exchange component 20 and the liquid inlet joint 40, and between the heat exchange component 20 and the liquid outlet joint 50, so that when the liquid inlet joint 40 and the liquid outlet joint 50 are installed and arranged in the battery 100, the layout positions of the liquid inlet joint 40 and the liquid outlet joint 50 are less restricted by the positions of the liquid inlet and the liquid outlet in the heat exchange component 20. The liquid inlet joint 40 and the liquid outlet joint 50 can be flexibly installed and arranged in the battery 100 according to the connection and assembly requirements with the external liquid supply equipment, so that the battery 100 can better meet the assembly requirements in the electrical device 1000.

[0082] In this embodiment, the adapter 30 is arranged on the other side of the expansion beam 122 in the second direction, which can facilitate the abutment arrangement of the expansion beam 122 and the battery assembly, and make the adapter 30 and the side wall surface of the accommodating cavity 101 in the second direction have a smaller distance, so that the liquid inlet connector 40 and the liquid outlet connector 50 can be more conveniently connected to the adapter 30.

[0083] It can be understood that in the second direction, when the space of the accommodating cavity 101 between the heat exchange component 20 and one side of the box body 10 on which the liquid inlet joint 40 and the liquid outlet joint 50 are provided is relatively narrow and cramped, the distance between the other side of the expansion beam 122 and the side wall of the accommodating cavity 101 of the box body 10 is small. When the liquid inlet and the liquid outlet of the heat exchange component 20 are connected to the liquid inlet joint 40 and the liquid outlet joint 50, a conventional elbow structure is used for connection, and there is insufficient space for arrangement, which makes it more difficult to connect the heat exchange component 20 with the liquid inlet joint 40 and the liquid outlet joint 50.

[0084] In this embodiment, an adapter 30 is provided so that the heat exchange component 20 can be connected to the adapter 30, and the adapter 30 is further connected to the liquid inlet connector 40 and the liquid outlet connector 50, so that the heat exchange component 20 can be conveniently connected to the liquid inlet connector 40 and the liquid outlet connector 50.
