Description

Technical Field

[0001] The present application relates to the field of battery technology, and more particularly, to a battery, an electrical device, and a method and system for manufacturing the battery. Background Art

[0002] Battery cells are widely used in electronic devices such as mobile phones, laptops, electric bicycles, electric cars, electric airplanes, electric boats, electric toy cars, electric toy boats, electric toy airplanes, and power tools. Battery cells can include nickel-cadmium battery cells, nickel-metal hydride battery cells, lithium-ion battery cells, and secondary alkaline zinc-manganese battery cells.

[0003] Batteries typically consist of multiple cells, electrically connected via a busbar. Each cell generates heat during operation, which can easily accumulate and cause the temperature of the cells to rise. Battery cells typically achieve optimal charge and discharge performance and a long lifespan when their operating temperature is between 20 and 40 degrees Celsius. Controlling the operating temperature of battery cells within a suitable range is a pressing technical challenge in battery technology. Summary of the Invention

[0004] The present application provides a battery, an electrical device, and a method and system for manufacturing the battery, which can improve the heat exchange effect and enable the battery cells of the battery to operate within a suitable temperature.

[0005] In a first aspect, an embodiment of the present application provides a battery, comprising:

[0006] The heat exchange component includes a first plate and two second plates, the two second plates are respectively connected to the ends of the first plate along a first direction, a preset angle is formed between the second plate and the first plate, the first plate and the two second plates enclose a receiving space, and the first plate is provided with a first flow channel for the flow of a heat exchange medium;

[0007] a battery unit, the battery unit being at least partially accommodated in the accommodation space of the heat exchange member, the battery unit comprising a plurality of battery cells sequentially arranged along a second direction, the heat exchange member being used to adjust the temperature of the battery cells, the second direction intersecting the first direction; and

[0008] The support component includes a support portion located on a side of the first plate body away from the accommodating space. The support portion is connected to the first plate body and is used to support the heat exchange component. A heat insulation structure is provided between the support portion and the first plate body.

[0009] In the above solution, the first plate can exchange heat with the battery cells, ensuring they operate at an appropriate temperature and improving their performance. The two second plates can secure the battery cells from both sides, enhancing the battery's structural strength and stability. The support portion can be directly mounted on the electrical device, eliminating the need for a traditional enclosure, improving space utilization, and reducing the number of components. The thermal insulation structure reduces heat transfer between the heat exchange component and the support member, ensuring a high heat exchange rate between the battery cells and the heat exchange component, allowing the battery cells to be adjusted to an appropriate operating temperature in a timely manner, thereby extending the battery's service life.

[0010] In some embodiments, the thermal insulation structure includes a gap provided in at least a partial area between the support portion and the first plate.

[0011] In the above solution, the gap separates at least a portion of the first plate from the support portion, thereby reducing the contact area between the first plate and the support portion and lowering the heat transfer rate between the first plate and the support portion.

[0012] In some embodiments, the thermal insulation structure further includes a thermal insulation layer, and the thermal insulation layer is disposed in the gap.

[0013] In the above solution, the heat insulating layer can hinder the heat transfer between the first plate body and the support portion, thereby reducing the influence of the support portion on the temperature of the first plate body.

[0014] In some embodiments, the first plate includes a first main portion, a first protrusion, and a second protrusion. The first and second protrusions protrude from a surface of the first main portion facing away from the receiving space. In the thickness direction of the first main portion, the first protrusion protrudes from the first main portion less than the second protrusion. The second protrusion supports the first main portion on the surface of the support portion. A gap is formed between the support portion and the first protrusion, at least partially. A first flow channel is formed within the first protrusion.

[0015] In the above scheme, by providing the first protrusion, the local thickness of the first plate can be increased, more space can be provided for the first flow channel, the flow area of ​​the first flow channel can be increased, and the heat exchange efficiency can be improved. The first protrusion protrudes toward the side away from the accommodating space, which can increase the flow area of ​​the first flow channel while avoiding the first flow channel occupying the accommodating space. The support portion is spaced apart from the first protrusion, so that the gravity load of components such as the battery cell is transferred to the support portion through the second protrusion, rather than being transferred to the support portion through the first protrusion. This can reduce the force on the first protrusion and reduce the risk of deformation and blockage of the first flow channel. The support portion is spaced apart from the first protrusion, which can increase the heat conduction path between the heat exchange medium in the first flow channel and the support portion, reduce the heat transfer rate between the heat exchange medium and the support portion, reduce the influence of the temperature of the support portion on the heat exchange medium, and ensure the heat exchange efficiency between the heat exchange component and the battery cell.

[0016] In some embodiments, the battery further includes two end plates, one located at each end of the battery cell along the second direction and clamping the battery cell. The two end plates, at their respective ends in the first direction, are connected to the two second plates. The support portion includes mounting areas at both ends along the second direction, extending outward from the end plates and configured to be secured to the external frame.

[0017] In this solution, the heat exchange component is connected to the end plate via the second plate, which improves the stability of the first plate and reduces the risk of separation between the first plate and the battery cells during battery shaking. The mounting area of ​​the support extends beyond the end plate, allowing the support to be directly secured to the external frame. This prevents the end plate from interfering with the connection between the support and the external frame, simplifying the battery structure.

[0018] In some embodiments, the battery further includes a connector, at least a portion of the first plate protrudes outward from the end plate and is used to mount the connector, and the connector is in communication with the first flow channel.

[0019] In the above solution, the connector is installed on the outside of the end plate, so the external liquid supply pipeline does not need to pass through the end plate, which can simplify the structure of the battery and make the layout of the external liquid supply pipeline more flexible.

[0020] In some embodiments, the mounting area has a through mounting hole for allowing an external connector to pass through so as to be fixed to the external frame through the external connector; in the thickness direction of the support portion, the mounting hole is not covered by the heat exchange component.

[0021] In the above solution, the mounting hole is not covered by the heat exchange component, which can prevent the heat exchange component from interfering with the installation of the external connector and simplify the installation process of the battery and the external frame.

[0022] In some embodiments, the end plates and the second plates extend beyond the battery cells in a direction away from the support portion, and the two end plates and the two second plates form an opening at one end away from the support portion. The battery further includes a cover plate located on a side of the battery cell away from the support portion and connected to the end plates and the second plates to close the opening.

[0023] In the above solution, the cover plate, end plates, and heat exchange components enclose a liquid-enclosed space for the battery cells, preventing liquids or other foreign matter from affecting the charging or discharging of the battery cells. The battery cells do not require the protection of a housing; the battery of this embodiment can be directly installed on the electrical device, thereby improving space utilization and reducing the number of components.

[0024] In some embodiments, the support member further includes two limiting portions, which are located on a side of the support member facing the heat exchange member and connected to the support member; in the first direction, the two second plates are located between the two limiting portions.

[0025] In the above solution, the limiting portion can limit the heat exchange component and the battery unit from both sides in the first direction. When the battery shakes, the limiting portion can reduce the shaking amplitude of the heat exchange component and the battery unit, thereby improving the overall stability of the battery.

[0026] In some embodiments, the second plate includes a second main body, a third protrusion, and a fourth protrusion. The third and fourth protrusions protrude from a surface of the second main body facing away from the receiving space. In the thickness direction of the second main body, the third protrusion protrudes from the first main body less than the fourth protrusion does, so that the fourth protrusion presses against the stop. The interior of the third protrusion forms a second flow channel that communicates with the first flow channel.

[0027] In the above solution, the provision of a third protrusion increases the local thickness of the second plate, providing more space for the second flow channel, increasing the flow area of ​​the second flow channel, and improving heat exchange efficiency. The third protrusion protrudes toward the side away from the storage space. This increases the flow area of ​​the second flow channel while preventing the second flow channel from occupying the storage space. Because the dimension of the third protrusion protruding from the second main body is smaller than the dimension of the fourth protrusion protruding from the second main body, the fourth protrusion can act as a stop when the battery shakes, reducing the possibility of components outside the second plate squeezing the third protrusion and reducing the risk of deformation and blockage of the second flow channel. The two limiters clamp the heat exchange component from both sides through the fourth protrusion to increase the connection strength between the heat exchange component and the support component and improve stability. In this embodiment, the provision of the fourth protrusion separates the third protrusion and the second main body from the limiter, reducing the contact area between the limiter and the second plate, thereby hindering heat transfer between the second plate and the limiter and reducing the impact of the limiter on the temperature of the second plate.

[0028] In some embodiments, a second flow channel communicating with the first flow channel is provided inside the second plate.

[0029] In the above solution, the first plate can exchange heat with the battery cells from below, and the second plate can exchange heat with the battery cells from the side. This increases the heat exchange area of ​​the battery cells, improves heat exchange efficiency, reduces the temperature difference between the battery cells along the thickness direction of the first plate, improves the temperature consistency of the battery cells, and enhances the operating performance of the battery cells. In this embodiment of the application, the first and second flow channels are connected, eliminating the need to connect the first and second flow channels to the external liquid supply pipeline separately, thereby simplifying the connection structure between the heat exchange component and the external liquid supply pipeline.

[0030] In some embodiments, the first flow channel and the second flow channel are connected at the connection between the first plate body and the second plate body; or, the heat exchange component further includes a connecting pipe to connect the first flow channel and the second flow channel.

[0031] In a second aspect, an embodiment of the present application provides an electrical device, comprising a battery according to any embodiment of the first aspect, wherein the battery is used to provide electrical energy.

[0032] In a third aspect, an embodiment of the present application provides a method for manufacturing a battery, comprising:

[0033] A heat exchange component is provided, comprising a first plate and two second plates, the two second plates being respectively connected to both ends of the first plate along a first direction, a preset angle being formed between the second plates and the first plate, the first plate and the two second plates forming a receiving space, and the first plate being provided with a first flow channel for a heat exchange medium to flow;

It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0064] The term "plurality" used in this application refers to two or more (including two).

[0065] In this application, battery cells may include lithium-ion secondary battery cells, lithium-ion primary battery cells, lithium-sulfur battery cells, sodium-lithium-ion battery cells, sodium-ion battery cells, or magnesium-ion battery cells, etc., and the embodiments of this application do not limit this. Battery cells may be cylindrical, flat, rectangular, or other shapes, etc., and the embodiments of this application do not limit this. Battery cells are generally divided into three types based on the packaging method: cylindrical battery cells, prismatic battery cells, and soft-pack battery cells, and the embodiments of this application do not limit this.

[0066] The battery referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. A battery generally includes a housing that encloses one or more battery cells. The housing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0067] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly includes a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell primarily operates by the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet includes a positive current collector and a positive active material layer, with the positive active material layer coated on the surface of the positive current collector. The positive current collector includes a positive current collector portion and a positive electrode tab protruding from the positive current collector portion. The positive current collector portion is coated with the positive active material layer, while at least a portion of the positive electrode tab is not coated with the positive active material layer. For example, in lithium-ion batteries, the positive current collector can be made of aluminum, and the positive active material layer includes a positive active material.

The material of the separator can be PP (polypropylene, polypropylene) or PE (polyethylene, polyethylene), etc. In addition, the electrode assembly can be a wound structure or a laminated structure, and the embodiments of the present application are not limited to this.

[0068] Battery cells generate heat during the charging and discharging process. When multiple battery cells are used in groups, this heat can accumulate. If this heat is not effectively removed, it will cause the battery cells to heat up and accelerate their aging. Furthermore, excessive temperatures can easily lead to thermal runaway, posing a safety risk. When battery cells are exposed to low temperatures, their service life is shortened and their discharge capacity is weakened.

[0069] The inventors have tried to set a heat exchange component in the battery to control the operating temperature of the battery cell within an appropriate range. Specifically, a flow channel is usually provided inside the heat exchange component. When the external heat exchange medium flows through the flow channel of the heat exchange component, the heat exchange medium exchanges heat with the battery cell through the heat exchange component to adjust the temperature of the battery cell. The heat exchange component usually needs to be set on a supporting structure, which is used to support the heat exchange component and the battery cell. However, the inventors found that the heat exchange component is easily affected by the temperature of the supporting structure. The heat exchange component exchanges heat with the battery cell and the supporting structure at the same time, resulting in a decrease in the heat exchange rate between the battery cell and the heat exchange component, making it impossible to adjust the operating temperature of the battery cell in time.

[0070] In view of this, an embodiment of the present application provides a battery, comprising: a heat exchange component, comprising a first plate and two second plates, the two second plates being respectively connected to the ends of the first plate along a first direction, the second plates being at a predetermined angle to the first plate, the first plate and the two second plates forming a storage space, the first plate being provided with a first flow channel for the flow of a heat exchange medium; a battery cell, the battery cell being at least partially accommodated in the storage space of the heat exchange component, the battery cell comprising a plurality of battery cells arranged sequentially along a second direction, the heat exchange component being configured to regulate the temperature of the battery cells, the second direction intersecting the first direction; and a support component, comprising a support portion located on a side of the first plate facing away from the storage space, the support portion being connected to the first plate and configured to support the heat exchange component, a heat insulation structure being provided between the support portion and the first plate. In this embodiment of the present application, a heat insulation structure is provided between the heat exchange component and the support component to reduce heat exchange between the heat exchange component and the support component, thereby ensuring a heat exchange rate between the battery cells and the heat exchange component, and timely adjusting the battery cells to an appropriate operating temperature.

[0071] The battery described in the embodiments of the present application is suitable for use in electrical devices that use the battery.

[0072] Electrical devices may include vehicles, mobile phones, portable devices, laptop computers, ships, spacecraft, electric toys, and electric tools, etc. Vehicles may include fuel vehicles, gas vehicles, or new energy vehicles. New energy vehicles may include pure electric vehicles, hybrid vehicles, or extended-range vehicles, etc. Spacecraft include airplanes, rockets, space shuttles, and spacecraft, etc. Electric toys include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Electric tools include metal cutting electric tools, grinding electric tools, assembly electric tools, and railway electric tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, etc. The embodiments of the present application do not impose any special restrictions on the above-mentioned electrical devices.

[0073] For the convenience of description, the following embodiments are described by taking a vehicle as an example of an electrical device.

The battery 2 can be used to power the vehicle 1, for example, the battery 2 can be used as an operating power source for the vehicle 1.

[0075] The vehicle 1 may further include a controller 3 and a motor 4 . The controller 3 is used to control the battery 2 to supply power to the motor 4 , for example, to meet the power requirements of the vehicle 1 during startup, navigation, and driving.

[0076] In some embodiments of the present application, the battery 2 can not only serve as the operating power source of the vehicle 1, but also serve as the driving power source of the vehicle 1, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1.

[0077] Figure 2 Schematic diagram of an explosion of a battery provided in some embodiments of the present application.

[0078] like Figure 2 As shown, the battery 2 includes a box 5 and a battery cell ( Figure 2 The battery cells are housed in the box body 5 .

[0079] The housing 5 is used to accommodate battery cells and can have various structures. In some embodiments, the housing 5 can include a first housing portion 51 and a second housing portion 52. The first housing portion 51 and the second housing portion 52 overlap each other and together define a storage space 53 for accommodating the battery cells. The second housing portion 52 can be a hollow structure with one end open. The first housing portion 51 is a plate-like structure, and the first housing portion 51 overlaps the open side of the second housing portion 52 to form the housing 5 with the storage space 53. The first housing portion 51 and the second housing portion 52 can also each be a hollow structure with one end open. The open side of the first housing portion 51 overlaps the open side of the second housing portion 52 to form the housing 5 with the storage space 53. Of course, the first housing portion 51 and the second housing portion 52 can have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0080] In order to improve the sealing performance after the first box body 51 and the second box body 52 are connected, a sealing member, such as a sealant, a sealing ring, etc., may also be provided between the first box body 51 and the second box body 52 .

[0081] Assuming that the first box portion 51 covers the top of the second box portion 52 , the first box portion 51 can also be referred to as an upper box cover, and the second box portion 52 can also be referred to as a lower box.

[0082] Battery 2 includes multiple battery cells. These cells can be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to a combination of series and parallel connections. Multiple battery cells can be directly connected in series, in parallel, or in a hybrid configuration, and then the entire battery module can be housed within housing 5. Alternatively, multiple battery cells can be first connected in series, in parallel, or in a hybrid configuration to form a battery module 6, and then multiple battery modules 6 can be connected in series, in parallel, or in a hybrid configuration to form a single unit housed within housing 5.

[0083] The housing 5 of the battery 2 is used to be mounted on an electrical device, for example, the housing can be mounted on the chassis of a vehicle by fasteners. The housing 5 can prevent liquid or other foreign matter from affecting the charging or discharging of the battery cells.

[0085] like Figures 3 to 6As shown, an embodiment of the present application provides a battery 2, including: a heat exchange member 20, including a first plate 21 and two second plates 22, the two second plates 22 being respectively connected to both ends of the first plate 21 along a first direction Y, with a preset angle between the second plate 22 and the first plate 21, the first plate 21 and the two second plates 22 enclosing a receiving space 23, the first plate 21 being provided with a first flow channel 211 for flowing a heat exchange medium; a battery cell 10, the battery cell 10 being at least partially received in the receiving space 23 of the heat exchange member 20, the battery cell 10 including a plurality of battery cells 11 arranged sequentially along a second direction X, the heat exchange member 20 being used to regulate the temperature of the battery cells 11, the second direction X intersecting with the first direction Y; and a support member 30, including a support portion 31 located on a side of the first plate 21 facing away from the receiving space 23, the support portion 31 being connected to the first plate 21 and used to support the heat exchange member 20, and a heat insulation structure 40 being provided between the support portion 31 and the first plate 21.

[0086] The battery cell 10 may be one or more. For example, the battery 2 includes a plurality of battery cells 10, and the plurality of battery cells 10 are arranged along a first direction Y. Optionally, the first direction Y is perpendicular to the second direction X. For example, in Figure 3 In the embodiment, there are two battery units 10 , in other words, a plurality of battery cells 11 are arranged in two rows.

[0087] The battery cell 11 is connected to the heat exchange component 20. Optionally, the battery cell 11 is bonded to the first plate 21 and the second plate 22 by heat conductive adhesive.

[0088] The multiple battery cells 11 in the battery 2 can be electrically connected via a busbar component to achieve parallel connection, series connection, or mixed connection of the multiple battery cells 11 in the battery 2 .

[0089] The heat exchange member 20 is used to regulate the temperature of the battery cells 11 so that the battery cells 11 operate at an appropriate temperature. For example, in the battery 2, the first plate 21 is located below the multiple battery cells 11 of the battery unit 10. The first plate 21 is used to support the battery cells 11 and regulate the temperature of the battery cells 11.

[0090] The first flow channel 211 is used to communicate with an external liquid supply pipeline. The heat exchange medium circulates between the first flow channel 211 and the external liquid supply pipeline to exchange heat with the battery cell 11 through the first plate 21, so that the battery cell 11 operates at a suitable temperature. The heat exchange medium can be liquid.

[0091] The first plate body 21 is made of a heat-conducting material. For example, the first plate body 21 is made of a heat-conducting metal.

[0092] In this embodiment, the first flow channel 211 can be formed on the first plate 21 by extrusion molding, inflation molding, or stamping molding.

[0093] The first plate 21 and the second plate 22 can be integrally formed; for example, the first plate 21 and the second plate 22 can be integrally formed by bending a plate. Of course, the first plate 21 and the second plate 22 can also be separate bodies, for example, the first plate 21 and the second plate 22 can be connected by welding, bonding, clamping, or other means.

[0094] The angle between the second plate 22 and the first plate 21 can be set as needed, and this embodiment does not limit this. For example, the angle between the second plate 22 and the first plate 21 is 80°-100°. The heat exchange component 20 is generally a U-shaped structure.

[0095] In battery 2, two second plates 22 are located on either side of the battery cell 10 along the first direction Y. They secure the battery cell 10 and enhance the overall strength of battery 2. The second plates 22 also provide a heat exchange function, regulating the temperature of the battery cells 11 from the side. Of course, the heat exchange function of the second plates 22 can also be omitted.

[0096] The support portion 31 is connected to the first plate 21 to improve the structural strength of the battery 2 and prevent the heat exchange component 20 from sliding relative to the support portion 31. For example, the support portion 31 can be connected to the first plate 21 by riveting, bolting, welding, bonding or other methods.

[0097] The support portion 31 is a supporting structure of the battery 2, and is used to support components such as the heat exchange component 20 and the battery cell 11. The support portion 31 plays an important role in improving the structural strength of the battery 2, and has a relatively high strength.

[0098] The support portion 31 has high strength, so the support portion 31 can be directly mounted on the electrical device (such as the chassis of a vehicle), thereby eliminating the need for a traditional box, improving space utilization, and reducing the use of parts. Alternatively, one or more batteries 2 according to embodiments of the present application can be first assembled into the box, and then mounted to the electrical device through the box.

[0099] The support portion 31 may be in contact with the heat exchange component 20 to directly support the heat exchange component 20 , or may indirectly support the heat exchange component 20 through other components.

[0100] The thermal insulation structure 40 is used to separate at least a portion of the first plate 21 from the support portion 31 to reduce the heat transfer rate between the support portion 31 and the first plate 21. The thermal insulation structure 40 can be a solid structure made of a material with a low thermal conductivity coefficient, or it can be a spatial structure such as a gap, which is not limited in this embodiment.

[0101] In the embodiment of the present application, the first plate 21 can exchange heat with the battery cell 11 so that the battery cell 11 operates at a suitable temperature, thereby improving the performance of the battery cell 11. The two second plates 22 can fix the battery cell 11 from both sides, thereby improving the structural strength and stability of the battery 2. The support portion 31 can be directly mounted on the electrical device, thereby eliminating the need for a traditional box, improving space utilization, and reducing the use of components. The heat insulation structure 40 can reduce the heat transfer between the heat exchange component 20 and the support component 30, thereby ensuring the heat exchange rate between the battery cell 11 and the heat exchange component 20, timely adjusting the battery cell 11 to a suitable operating temperature, and extending the service life of the battery 2.

[0102] In some embodiments, the thermal insulation structure 40 includes a gap 41 , which is provided in at least a partial area between the support portion 31 and the first plate 21 .

[0103] The gap 41 may be filled with a heat insulating material or may not be filled with a heat insulating material.

[0104] The gap 41 separates at least a portion of the first plate 21 from the support portion 31 to reduce the contact area between the first plate 21 and the support portion 31 and lower the heat transfer rate between the first plate 21 and the support portion 31 .

[0105] In some embodiments, the thermal insulation structure 40 further includes a thermal insulation layer 42 , which is disposed in the gap 41 .

[0106] The heat insulating layer 42 may completely fill the gap 41 between the first plate 21 and the support portion 31 , or may only fill a portion of the gap 41 .

[0107] The heat insulating layer 42 may be a whole piece or a plurality of separate pieces.

[0108] The thermal conductivity of the heat insulating layer 42 is smaller than the thermal conductivity of the support portion 31 and the thermal conductivity of the first plate 21 .

[0109] The thermal insulation layer 42 can hinder heat transfer between the first plate 21 and the support portion 31, reducing the impact of the support portion 31 on the temperature of the first plate 21. It should be noted that the thermal insulation layer 42 does not need to be completely insulating; it can simply reduce the efficiency of heat conduction. Non-metallic materials are preferred. For example, the thermal insulation layer 42 can be made of fiberglass, asbestos, rock wool, silicate, or aerogel felt.

[0110] Optionally, the heat insulating layer 42 also has a connecting function, which can reliably fix the first plate 21 on the support portion 31, thereby improving the structural strength of the entire battery 2. For example, the heat insulating layer 42 is formed by curing an adhesive.

[0111] Optionally, the thermal insulation layer 42 also has a buffering function. The thermal insulation layer 42 has good elasticity and can act as a buffer when the battery 2 shakes, thereby reducing the impact force on the first plate 21 and reducing the risk of deformation and blockage of the first flow channel 211.

[0112] In some embodiments, the first plate 21 includes a first main portion 212, a first protrusion 213, and a second protrusion 214. The first protrusion 213 and the second protrusion 214 protrude from the surface of the first main portion 212 facing away from the accommodating space 23. In the thickness direction of the first main portion 212, the protrusion of the first protrusion 213 from the first main portion 212 is smaller than the protrusion of the second protrusion 214 from the first main portion 212. The second protrusion 214 supports the first main portion 212 on the surface of the support portion 31. The gap 41 is formed at least partially between the support portion 31 and the first protrusion 213. The first flow channel 211 is formed within the first protrusion 213.

[0113] The first main body portion 212 is generally a flat plate structure, and the surfaces of the first main body portion 212 opposite to each other along the thickness direction thereof are flat surfaces.

[0114] There can be one or more first protrusions 213. When there are multiple first protrusions 213, each first protrusion 213 has a first flow channel 211. The first flow channels 211 of the multiple first protrusions 213 can be directly connected or connected through other connecting structures, such as connecting pipes.

[0115] There may be one or more second protrusions 214. The second protrusions 214 may be circular, rectangular, racetrack-shaped, elliptical, or other shapes. The second protrusions 214 may be connected to the support portion 31 by riveting, bolting, welding, or bonding. Optionally, each battery cell 11 may be provided with a second protrusion 214 on its underside. This allows the heat exchange component 20 to more evenly transfer the gravity load to the support portion 31, reducing stress concentration.

[0116] The second protrusion 214 protrudes from the first main body 212 to a greater extent than the first protrusion 213 does, so the second protrusion 214 presses against the support portion 31 to spread the first main body 212 and the first protrusion 213 apart and to separate the first protrusion 213 from the support portion 31.

[0117] In the embodiment of the present application, by providing the first protrusion 213, the local thickness of the first plate 21 can be increased, providing more space for the first flow channel 211, increasing the flow area of ​​the first flow channel 211, and improving the heat exchange efficiency. The first protrusion 213 protrudes toward the side away from the accommodating space 23. This can increase the flow area of ​​the first flow channel 211 while preventing the first flow channel 211 from occupying the accommodating space 23. The support portion 31 is spaced apart from the first protrusion 213. Therefore, the gravity load of components such as the battery cell 11 is transferred to the support portion 31 through the second protrusion 214, and is not transferred to the support portion 31 through the first protrusion 213. This can reduce the force on the first protrusion 213 and reduce the risk of deformation and blockage of the first flow channel 211. The support portion 31 is spaced apart from the first protrusion 213 , which can increase the heat conduction path between the heat exchange medium in the first flow channel 211 and the support portion 31 , reduce the heat transfer rate between the heat exchange medium and the support portion 31 , and reduce the influence of the temperature of the support portion 31 on the heat exchange medium, thereby ensuring the heat exchange efficiency between the heat exchange component 20 and the battery cell 11 .

[0118] In some embodiments, the first plate 21 has a first recess 215 at a position corresponding to the second protrusion 214. The first recess 215 is recessed relative to the surface of the first main body 212 facing the accommodating space 23. The first recess 215 can reduce the weight of the first plate 21 and increase the elasticity of the second protrusion 214, thereby providing a certain cushioning effect.

[0119] In some embodiments, a second flow channel 221 is provided within the second plate 22. The second flow channel 221 is used to communicate with an external liquid supply pipeline. A heat exchange medium circulates between the second flow channel 221 and the external liquid supply pipeline to exchange heat with the battery cells 11 through the second plate 22, allowing the battery cells 11 to operate at a suitable temperature.

[0120] The second flow channel 221 may be in communication with the first flow channel 211 or may not be in communication with the first flow channel 211 , which is not limited in this embodiment.

[0121] In this embodiment, the first plate 21 can exchange heat with the battery cell 11 from the bottom, and the second plate 22 can exchange heat with the battery cell 11 from the side. This can increase the heat exchange area of ​​the battery cell 11, improve the heat exchange efficiency, reduce the temperature difference of the battery cell 11 in the thickness direction of the first plate 21, improve the temperature consistency of the battery cell 11, and improve the working performance of the battery cell 11.

[0122] In some embodiments, a second flow channel 221 communicating with the first flow channel 211 is defined inside the second plate 22 .

[0123] The second flow channel 221 may be directly connected to the first flow channel 211 or indirectly connected to the first flow channel 211 through other components, which is not limited in this embodiment.

[0124] In the embodiment of the present application, the first flow channel 211 and the second flow channel 221 are connected, so there is no need to connect the first flow channel 211 and the second flow channel 221 to the external liquid supply pipeline separately, thereby simplifying the connection structure between the heat exchange component 20 and the external liquid supply pipeline.

[0125] In some embodiments, the support member 30 further includes two limiting portions 32 , which are located on the side of the support portion 31 facing the heat exchange member 20 and connected to the support portion 31 ; in the first direction Y, the two second plates 22 are located between the two limiting portions 32 .

[0126] The limiting portion 32 may be integrally formed with the supporting portion 31 , or may be connected to the supporting portion 31 by welding, riveting, bonding, or the like.

[0127] There is a certain angle between the limiting portion 32 and the supporting portion 31. Optionally, the angle between the limiting portion 32 and the supporting portion 31 is 80°-100°.

[0128] The limiting portion 32 can limit the heat exchange component 20 and the battery cell 10 from both sides of the first direction Y. When the battery 2 shakes, the limiting portion 32 can reduce the shaking amplitude of the heat exchange component 20 and the battery cell 10, thereby improving the overall stability of the battery 2.

[0129] The limiting portion 32 can be connected to the second plate 22 by riveting, bolting, welding, bonding, etc., so as to increase the overall structural strength of the battery 2 and improve stability.

[0130] In some embodiments, a heat insulating structure may be provided between the stopper 32 and the second plate 22 to hinder heat transfer between the second plate 22 and the stopper 32, thereby reducing the effect of the stopper 32 on the temperature of the second plate 22. The heat insulating structure between the stopper 32 and the second plate 22 includes, but is not limited to, a gap, a heat insulating layer (not shown), and other structures.

[0131] In some embodiments, the second plate 22 includes a second main body 222, a third protrusion 223, and a fourth protrusion 224. The third protrusion 223 and the fourth protrusion 224 protrude from the surface of the second main body 222 facing away from the accommodating space 23. In the thickness direction of the second main body 222, the protrusion of the third protrusion 223 from the first main body 212 is smaller than the protrusion of the fourth protrusion 224 from the first main body 212, so that the fourth protrusion 224 presses against the stopper 32. The interior of the third protrusion 223 forms a second flow channel 221 that communicates with the first flow channel 211.

[0132] The second main body portion 222 is substantially a flat plate structure, and the surfaces of the second main body portion 222 that are opposite to each other along the thickness direction thereof are flat surfaces.

[0133] There can be one or more third protrusions 223. When there are multiple third protrusions 223, each third protrusion 223 has a second flow channel 221. The second flow channels 221 of the multiple third protrusions 223 can be directly connected or connected through other connecting structures, such as connecting pipes.

[0134] There may be one or more fourth protrusions 224. The fourth protrusions 224 may be circular, rectangular, racetrack-shaped, elliptical, or other shapes.

[0135] The fourth protrusion 224 protrudes from the second main body portion 222 to a greater extent than the third protrusion 223 protrudes from the second main body portion 222 .

[0136] In the embodiment of the present application, by providing the third protrusion 223, the local thickness of the second plate body 22 can be increased, providing more space for the second flow channel 221, increasing the flow area of ​​the second flow channel 221, and improving the heat exchange efficiency. The third protrusion 223 protrudes toward the side away from the accommodating space 23. This can increase the flow area of ​​the second flow channel 221 while preventing the second flow channel 221 from occupying the accommodating space 23. Since the size of the third protrusion 223 protruding from the second main body 222 is smaller than the size of the fourth protrusion 224 protruding from the second main body 222, when the battery 2 is shaken, the fourth protrusion 224 can act as a stop, reducing the possibility of the components outside the second plate body 22 squeezing the third protrusion 223, and reducing the risk of deformation and blockage of the second flow channel 221.

[0137] The two stoppers 32 clamp the heat exchange component 20 from both sides via the fourth protrusion 224, thereby increasing the connection strength and stability between the heat exchange component 20 and the support member 30. In this embodiment, the fourth protrusion 224 separates the third protrusion 223 and the second main body 222 from the stoppers 32, reducing the contact area between the stoppers 32 and the second plate 22. This hinders heat transfer between the second plate 22 and the stoppers 32, thereby reducing the impact of the stoppers 32 on the temperature of the second plate 22.

[0138] In the first direction Y, the limiting portion 32 may or may not overlap with the third protrusion 223. Even if the limiting portion 32 and the third protrusion 223 overlap in the first direction Y, the fourth protrusion 224 can still prop up the limiting portion 32 to separate the limiting portion 32 and the third protrusion 223, thereby preventing the third protrusion 223 from being squeezed by the limiting portion 32 and reducing heat transfer between the third protrusion 223 and the limiting portion 32.

[0139] In some embodiments, the second plate 22 is provided with a second recess 225 at a position corresponding to the fourth protrusion 224. The second recess 225 is recessed relative to the surface of the second main body 222 facing the accommodating space 23. The second recess 225 can reduce the weight of the second plate 22 and increase the elasticity of the fourth protrusion 224, thereby providing the fourth protrusion 224 with a certain cushioning effect.

[0140] Figure 7 A schematic structural diagram of a heat exchange component of a battery provided in some embodiments of the present application.

[0141] like Figure 7 As shown, the first flow channel and the second flow channel are connected at the connection between the first plate 21 and the second plate 22. In this embodiment, the first flow channel and the second flow channel inside the heat exchange component 20 are directly connected, without the need for other structures to connect the first flow channel and the second flow channel, thereby simplifying the structure of the heat exchange component 20.

[0142] For example, in Figure 7 In the embodiment, the first flow channel is located inside the first convex portion 213, and the second flow channel is located inside the third convex portion 223; the first convex portion 213 and the third convex portion 223 are connected so that the first flow channel and the second flow channel are directly connected.

[0143] Figure 8 Schematic diagram of the structure of the heat exchange component of the battery provided in other embodiments of the present application.

[0144] like Figure 8 As shown, in some embodiments, the heat exchange component 20 further includes a connecting pipe 24 to connect the first flow channel and the second flow channel.

[0145] In this embodiment, the connection pipe 24 can make the communication between the first flow channel and the second flow channel more flexible.

[0146] For example, in Figure 8 In the embodiment, the first flow channel is located inside the first convex portion, and the second flow channel is located inside the third convex portion 223.

[0147] Figure 9 for Figure 3 An enlarged schematic diagram of the battery shown at circle A.

[0148] Please refer to Figure 3 and Figure 9 In some embodiments, the battery 2 further includes two end plates 50, which are located at both ends of the battery cell 10 along the second direction X and clamp the battery cell 10. The end plates 50 are connected to the two second plates 22 at their respective ends in the first direction Y. The support portion 31 has mounting areas 311 at both ends along the second direction X. The mounting areas 311 extend outside the end plates 50 and are used to be fixed to the external frame.

[0149] Both ends of the end plate 50 in the first direction Y can be connected to the two second plates 22 by welding or the like. The two end plates 50 and the two second plates 22 form a frame structure to fix the battery cells 11 .

[0150] In this embodiment, the heat exchange member 20 is connected to the end plate 50 via the second plate 22. This improves the stability of the first plate and reduces the risk of separation between the first plate and the battery cell 11 when the battery 2 is shaken. The mounting area 311 of the support portion 31 extends outside the end plate 50, allowing the support portion 31 to be directly fixed to an external frame (such as a vehicle chassis), preventing the end plate 50 from interfering with the connection between the support portion 31 and the external frame, and simplifying the structure of the battery 2.

[0151] In some embodiments, the battery 2 further includes a connector 60 . At least a portion of the first plate protrudes outward from the end plate 50 and is used to mount the connector 60 . The connector 60 is in communication with the first flow channel.

[0152] The connector 60 is used to connect to an external liquid supply pipeline. The connector 60 may include a liquid inlet connector and a liquid outlet connector. The heat exchange medium flows into the first flow channel through the liquid inlet connector and then flows out through the liquid outlet connector.

[0153] For example, the first plate body may include two protruding areas 216, each protruding area 216 protruding outward from the end plate 50 and being used to mount a liquid inlet connector and a liquid outlet connector, respectively. The two protruding areas 216 may be located at either end of the first plate body along the second direction X, or at the same end of the first plate body along the second direction X.

[0154] In this embodiment, the connector 60 is installed on the outside of the end plate 50, so the external liquid supply pipeline does not need to pass through the end plate 50, which can simplify the structure of the battery 2 and make the layout of the external liquid supply pipeline more flexible.

[0155] In some embodiments, the mounting area 311 has a through mounting hole 312 for an external connector to pass through so as to be fixed to the external frame. In the thickness direction of the support portion 31 , the mounting hole 312 is not covered by the heat exchange member 20 .

[0156] Alternatively, the external connection member may be a fastener, such as a bolt.

[0157] There can be one or more mounting holes 312. The mounting holes 312 can be threaded holes or through holes without threads.

[0158] In this embodiment, the mounting hole 312 is not covered by the heat exchange component 20 , which can prevent the heat exchange component 20 from interfering with the installation of external connectors and simplify the installation process of the battery 2 and the external frame.

[0159] In some embodiments, the protruding area 216 and the mounting hole 312 are spaced apart in the first direction Y, which can reduce the risk of interference between the connector 60 and external connectors.

[0160] In some embodiments, the end plates 50 and the second plates 22 extend beyond the battery cells 11 in a direction away from the support portion 31 , and the two end plates 50 and the two second plates 22 form an opening at one end away from the support portion 31 .

[0161] Figure 10 This is a schematic diagram of the structure of the battery provided in some other embodiments of the present application. Figure 10 As shown, in some embodiments, the battery 2 further includes a cover plate 70 , which is located on a side of the battery unit away from the support portion 31 and is connected to the end plate 50 and the second plate body 22 to close the opening.

[0162] The cover plate 70 may be a plate-shaped structure or a hollow structure with one side open.

[0163] The cover plate 70 may be connected to the end plate 50 and the second plate body 22 by welding, riveting, bonding or other methods.

[0164] The cover plate 70, end plate 50, and heat exchange member 20 form a liquid-enclosed space for accommodating the battery cells, preventing liquids or other foreign matter from affecting the charging or discharging of the battery cells. The battery cells do not require the protection of a housing; the battery 2 of this embodiment can be directly mounted on an electrical device, thereby improving space utilization and reducing the number of components.
