Description

Heat exchange components, batteries and electrical equipment Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a heat exchange component, a battery, and an electrical device. Background Art

[0002] Heat is generated during battery operation. When multiple battery cells are installed at the same time, the temperatures of the multiple battery cells are uneven due to the different temperature rises of the multiple battery cells, which in turn makes the battery prone to thermal runaway and affects power safety.

[0003] Summary of the Invention

[0004] The main purpose of this application is to propose a heat exchange component to solve the current problem of thermal runaway of battery cells.

[0005] To achieve the above objectives, the heat exchange component proposed in the example of this application includes at least two flow channels, including a first flow channel and a second flow channel. The first flow channel is provided with a first inlet, and the second flow channel is provided with a second inlet. The first inlet and the second inlet are provided independently of each other.

[0006] In this example, at least two flow channels are set up, and the first inlet and the second inlet corresponding to the two flow channels are set independently of each other, so that the heat exchange medium can be input through different inlets respectively, and then the first flow channel and the second flow channel can realize different refrigerant input, so that the areas corresponding to the first flow channel and the second flow channel can realize different temperature management, thereby reducing the risk of thermal runaway of the battery.

[0007] In some examples, the first flow channel further includes a first outlet, and the second flow channel further includes a second outlet, and the first outlet and the second outlet are configured to be independent of each other or integrally provided.

[0008] In this example, the first and second outlets are provided on the first and second flow channels, respectively, to facilitate the output of the heat exchange medium. When the first and second outlets are provided independently, the heat exchange medium of the two flow channels can be independently output. When the first and second outlets are provided as a single unit, the outlet configuration of the pipeline can be simplified, improving the simplicity of the overall structure.

[0009] In some examples, the heat exchange assembly includes a first plate and a second plate, the second plate is arranged adjacent to the first plate and at an angle to the first plate, a first branch channel is formed in the first plate, a second branch channel is formed in the second plate, and the first branch channel and the second branch channel are connected to form a first channel.

[0010] In this example, a first plate and a second plate are used in conjunction, corresponding to the first and second branch channels, respectively. This extends the total length of the flow path of the heat exchange medium transported by the first channel through the heat exchange assembly, thereby fully utilizing the heat of the heat exchange medium in the first channel and improving its utilization efficiency. Because the first plate and the second plate can be combined to form an area for mounting multiple battery cells, independent thermal management can be achieved for the battery cells installed in this area.

[0011] In some examples, the heat exchange assembly also includes a third plate, which is adjacent to the first plate and arranged at an angle to the first plate. A third branch channel is also formed in the first plate, and a fourth branch channel is formed in the third plate. The third branch channel and the fourth branch channel are connected to form a second channel.

[0012] In this example, a third branch channel is formed on the first plate, and a fourth branch channel is formed on the third plate and connected to the third branch channel to form a second channel, so that the third plate and the first plate are combined to form another area for installing multiple battery cells, which can realize independent thermal management of multiple battery cells in another area.

[0013] In some examples, the first inlet is located on the second plate, the first outlet is located on the first plate, and the second inlet is located on the third plate and the second outlet is located on the first plate; in other examples, the first inlet may be located on the second plate and the first outlet may be located on the first plate; in still other examples, the second inlet may be located on the third plate and the second outlet may be located on the first plate.

[0014] In this example, the first inlet is located on the second plate, allowing the heat exchange medium to flow through the second plate toward the first plate, thereby extending the length of the heat exchange medium's flow path. In this example, the second inlet is located on the third plate, allowing the heat exchange medium in the second flow channel to flow through the third plate toward the first plate, thereby extending the flow path of the heat exchange medium in the second flow channel and improving the efficiency of the heat exchange medium.

[0015] In some examples, the first inlet is located at an end of the second plate away from the first plate, and the second inlet is located at an end of the third plate away from the first plate; in other examples, only the first inlet may be located at an end of the second plate away from the first plate; in still other examples, only the second inlet may be located at an end of the third plate away from the first plate.

[0016] In this example, the first inlet is arranged at an end of the second plate away from the first plate, so that the flow path of the heat exchange medium is extended. When the second plate is arranged upward, the first inlet can be arranged at the upper end of the second plate, thereby allowing the heat exchange medium to flow downward under the action of gravity, thereby reducing the flow resistance of the heat exchange medium.

[0017] In this example, the second inlet is arranged at the end of the third plate away from the first plate, so that the flow path of the heat exchange medium is extended. When the third plate is arranged upward, the second inlet can be arranged at the upper end of the third plate, thereby allowing the heat exchange medium to flow downward under the action of gravity, thereby reducing the flow resistance of the heat exchange medium.

[0018] In some examples, the first and second runners are connected at the intersection of the angle between the first and second plates, and the third and fourth runners are connected at the angle between the first and third plates. In other examples, only the first and second runners are connected at the angle between the first and second plates, or only the third and fourth runners are connected at the angle between the first and third plates.

[0019] In some examples of this application, the first and second diverter channels intersect at the angle between the first and second plates, so that the connection between the two channels is located inside the heat exchange assembly, thereby reducing external connectors and simplifying the overall structure. In some examples of this application, the third and fourth diverter channels are located at the angle between the first and third plates, so that the connection between the third and fourth diverter channels is located inside the heat exchange assembly, reducing external connecting structures, facilitating splicing, and facilitating the flow channel molding of the heat exchange assembly.

[0020] In some examples, the first plate is provided in a split configuration, and the split first plate includes a first portion and a second portion, and the first portion and the second portion are used to arrange the first branch channel and the third branch channel, respectively.

[0021] Since the first plate is arranged separately, when the first part of the first plate and the second plate form a first flow channel, and the second part of the first plate and the third plate form a second flow channel, two independent heat exchange parts are formed on the heat exchange component, which can be used to install two groups of battery cells, thereby facilitating zoned thermal management.

[0022] In some examples, the first portion and the second portion are connected and fixed along a first direction. In this example, the first portion and the second portion are independently provided and connected and fixed along the first direction, so that the first portion and the second portion maintain a preset position to facilitate pipe connection and fixation.

[0023] In some examples, the second plate and the third plate are located on both sides of the first plate along the first direction, and the second plate is connected to the first portion, and the third plate is connected to the second portion.

[0024] In this example, the second plate and the first portion of the first plate can form a generally L-shaped structure, and the third plate and the second portion of the first plate can form a generally L-shaped structure to facilitate positioning of the battery and to be compatible with the surface of the battery cell.

[0025] In some examples, the first portion is integrally provided with the second plate, and the second portion is integrally provided with the third plate; in other examples, the first portion may be integrally provided with the second plate; in still other examples, the second portion may be integrally provided with the third plate.

[0026] In this example, part of the first plate is integrally formed with the second plate to facilitate overall molding; the second part of the first plate is integrally formed with the third plate so that the second part of the first plate and the third plate form a generally L-shaped structure to enhance the stability of the structure while facilitating the molding of the flow path.

[0027] In some examples, the first and third flow channels are arranged along a first direction. In this example, by arranging the first and third flow channels along the first direction, the first and second flow channels corresponding to the first and third flow channels are arranged along the first direction, thereby forming two areas arranged along the first direction for mounting battery cells, thereby achieving zoned thermal management of battery cells in different areas.

[0028] In some examples, the first outlet and the first inlet are located at opposite ends in the second direction, and the second outlet and the second inlet are located at opposite ends in the second direction, and the second direction intersects with the first direction; in some examples, the first outlet and the first inlet are located at opposite ends in the second direction, and the second direction intersects with the first direction; in some examples, the second outlet and the second inlet are located at opposite ends in the second direction, and the second direction intersects with the first direction.

[0029] In some examples, the first outlet and the first inlet are located at both ends in the second direction, so that the first inlet and the first outlet are staggered with each other, thereby extending the flow path of the heat exchange medium and improving the heat utilization rate of the heat exchange medium; in some examples, the second outlet and the second inlet are located at opposite ends in the second direction, so that the flow path of the heat exchange medium in the second flow channel is extended, thereby improving the heat utilization rate of the heat exchange medium.

[0030] In some examples, the heat exchange assembly further includes a first input connector and a second input connector, which are mounted on the first inlet and the second inlet, respectively. In this example, the first input connector and the second input connector are mounted on the first inlet and the second inlet, respectively, to facilitate the input of the heat exchange medium.

[0031] In some examples, the heat exchange assembly further includes an input manifold including a water inlet and multiple water outlets connected to the water inlet, two of the multiple water outlets are respectively connected to the first input connector and the second input connector.

[0032] In this example, a single input manifold is used to realize centralized input of the heat exchange medium, which makes it easy to install the heat exchange component on the electrical equipment, thereby simplifying the input structure of the heat exchange medium and improving the space utilization of the electrical equipment.

[0033] In some examples, the input manifold is provided with a flow control switch, which is used to control the rate at which the heat exchange medium enters the first flow channel and the second flow channel. By setting the flow control switch to control the rate at which the heat exchange medium enters the first flow channel and the second flow channel, the input amount of the heat exchange medium into the first flow channel and the second flow channel can be controlled, thereby achieving temperature control of battery cells in different areas as needed.

[0034] In some examples, the flow control switch is used to control the rate at which the heat exchange medium enters the first flow channel to be greater than the rate at which the heat exchange medium enters the second flow channel. Because the rate of the first flow channel is greater than the rate of the second flow channel, the flow rate of the heat exchange medium in the battery cells corresponding to the first flow channel is greater than the flow rate of the heat exchange medium in the second flow channel, thereby achieving thermal management at different temperatures and ensuring that the heat exchange efficiency of the heat exchange medium is consistent with the heat exchange requirements of the battery cells in the corresponding area.

[0035] In some examples, the first outlet and the second outlet are configured to be independently provided on the first plate, and the heat exchange assembly further includes a first output connector and a second output connector, which are connected to the first outlet and the second outlet, respectively. In this example, the first outlet and the second outlet are independently provided to achieve independent output of the heat exchange medium. By providing the first output connector and the second output connector separately, it is convenient to connect to external pipelines, thereby achieving rapid docking and stable output.

[0036] In some examples, the heat exchange assembly further includes an output manifold, which includes multiple water inlets and a water outlet connected to the multiple water inlets, with two of the multiple water inlets correspondingly connected to the first output connector and the second output connector, respectively. The output manifold facilitates centralized output of the heat exchange medium from the first and second flow channels, thereby reducing the number of piping in the heat exchange assembly and improving the efficiency of heat exchange medium output.

[0037] In some examples, the heat exchange component further includes a first input connector and a second input connector as described in any of the above examples, and a first output connector and a second output connector as described in any of the above examples, and the first input connector, the second input connector, the first output connector and the second output connector are all located at the same end of the heat exchange component along a third direction, and the third direction is perpendicular to the first direction and the second direction in pairs.

[0038] In this example, the first input connector, the second input connector, the first output connector, and the second output connector are all located at the same end of the heat exchange component along the third direction, so that the connector parts are all located on the same side of the heat exchange component, thereby facilitating the arrangement of pipelines. When the heat exchange component is used for electrical equipment, external pipelines can be conveniently connected to improve space utilization.

[0039] In some examples, the heat exchange assembly has a first end and a second end disposed opposite each other along a third direction, and a limit member is provided at the first and second ends of the heat exchange assembly. In other examples, a limit member may be provided at the first end of the heat exchange assembly; in still other examples, a limit member may be provided at the second end of the heat exchange assembly. The limit member in this example can be used to prevent movement of the battery cell, thereby maintaining the battery cell in a preset position and reducing the possibility of displacement of the battery cell.

[0040] In some examples, the first flow channel and the second flow channel each include a plurality of sub-flow channels connected in parallel, and the first flow channel and the second flow channel are configured to differ in at least one of the number of sub-flow channels, the total width of the sub-flow channels, and the total area of ​​the sub-flow channels.

[0041] In this example, by controlling the difference in parameters between the first flow channel and the second flow channel, the flow rates of the heat exchange medium in the first flow channel and the second flow channel are adjusted, thereby achieving regional thermal management according to the needs of specific battery cells.

[0042] The present application also proposes an example of a battery, which includes a battery cell and a heat exchange component as described in any of the above examples, and the heat exchange component is used for heat exchange with the battery cell.

[0043] In some examples, the heat exchange assembly includes a first plate and a second plate, the second plate being disposed adjacent to and at an angle to the first plate. The first plate has a first flow channel formed therein, the second plate has a second flow channel formed therein, and the first and second flow channels are interconnected to form a first flow channel. The battery also includes a base plate, the first plate being fixedly connected to the base plate. In this example, the first plate is fixed to the base plate to achieve overall positional restraint of the heat exchange assembly, thereby reducing the possibility of displacement of the heat exchange assembly.

[0044] In some examples, the first outlet and the first inlet are located at opposite ends in the second direction, and the second outlet and the second inlet are located at opposite ends in the second direction, with the second direction intersecting the first direction. In other examples, the first outlet and the first inlet may be located at opposite ends in the second direction; in still other examples, the second outlet and the second inlet may be located at opposite ends in the second direction. The first and third flow channels extend along the first direction to form two mounting positions, each of which contains at least one battery cell. In this example, two mounting positions are formed so that two independent mounting positions can be used to mount corresponding battery cells, respectively. Thermal management of the battery cells in the two mounting positions is achieved through the first and second flow channels.

[0045] In some examples, a battery pack is placed on each of the two mounting locations. The battery pack is configured to be formed by arranging multiple battery cells along a third direction. By arranging the battery cells along the third direction to form a battery pack, the first flow channel and the second flow channel act on the corresponding battery pack, respectively, to achieve independent thermal management of each battery pack.

[0046] In some examples, the battery further includes an end plate located at an end of the battery pack along the third direction, and the end plate is located between the battery pack and the limiting member.

[0047] The end plates in this example can be used to block the battery pack to reduce the possibility of displacement of the battery pack, thereby improving the stability of the battery pack.

[0048] The present application also proposes an example of an electrical device, which includes a battery as described in any of the above examples.

[0049] In some examples, the battery is a battery as described in the above examples, the electrical device includes a mounting component, and the substrate is used for mounting with the mounting component. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0064] With the advancement of battery technology, batteries have become ubiquitous in every aspect of our lives and work. From small mobile phone batteries to large batteries for new energy vehicles, batteries are everywhere. Lithium batteries are a common battery structure. Lithium batteries are rechargeable batteries that generally use materials containing lithium as electrodes and rely primarily on the movement of lithium ions between positive and negative electrodes to function.

[0065] In order to achieve a preset voltage output, in some cases, batteries are combined to form a battery pack. An electrode assembly is provided inside a battery cell. The electrode assembly may include a current collector and an active material layer provided on the current collector. The current collector is usually made of copper foil and aluminum foil. The current collector has the function of supporting the active material layer and can collect the electrons generated by the electrochemical reaction and conduct them to the external circuit, thereby realizing the process of converting chemical energy into electrical energy. During the electrochemical reaction of the battery, the battery generates heat, causing the temperature of the battery pack to rise, affecting the safe use of the battery pack.

[0066] In order to ensure that the batteries obtain sufficient power, they are usually arranged according to a preset pattern. For example, one row of multiple columns, or multiple rows of multiple columns, are used so that the battery packs can be placed in a certain pattern, which makes it convenient to combine the batteries into a preset voltage output module through connectors.

[0067] The applicant discovered that during the use of the battery pack, the temperature rise at different locations in the battery pack varies due to differences in the amount of heat generated by battery cells at different locations. In order to improve the safety of the battery pack, it is necessary to control the temperature of the battery pack to reduce the possibility of thermal runaway. In some cases, a heat exchange device is provided on the outside of the battery pack, and the temperature of the battery pack is controlled by heat exchange with the battery pack. Since the heat required by battery cells at different locations in the battery pack is different, when the heat exchange device controls the temperature of the battery pack as a whole, it is easy to cause insufficient heat exchange of some battery cells in the battery pack, thereby affecting the safe use of the battery pack.

[0068] Based on the above considerations, in order to solve the problem of thermal runaway of the battery pack caused by insufficient heat exchange between battery cells at different positions of the heat exchange device used to control the thermal control of the battery pack, a heat exchange assembly is designed, which includes at least two flow channels, each of which has an inlet, and the inlets of the flow channels are arranged independently of each other.

[0069] In a heat exchange component of this structure, by setting the inlets of at least two flow channels independently of each other, the corresponding flow channels can be used to input heat exchange medium respectively, and the heat exchange medium can flow along the corresponding flow channels. When the battery cells are installed at the positions corresponding to the flow channels, the temperature of the battery cells at the positions where the flow channels are located can be controlled through the corresponding flow channels, thereby reducing the risk of thermal runaway caused by insufficient heat exchange of the heat exchange medium to the battery cells at different positions in the battery pack.

[0070] The batteries disclosed in the examples of this application can be used, but are not limited to, in electrical equipment such as vehicles, ships, or aircraft. A power supply system comprising the heat exchange assembly disclosed in this application and a battery can be used to construct such an electrical equipment. This helps expand the application scope of the heat exchange assembly and reduces the difficulty of assembling the heat exchange assembly.

[0071] The present application provides an example of an electric device that uses a battery as a power source. The electric device may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, etc. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc. The spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0072] For the convenience of description, the following embodiments are described by taking a vehicle as an example of an electrical device in an example of the present application.

[0073] This application provides an example of an electric device, which includes a battery 100. The electric device includes, but is not limited to, mobile phones, portable devices, laptop computers, battery cars, electric vehicles, ships, spacecraft, electric toys, electric tools, and the like.

[0074] Please refer to Figure 1. A driving device 200, a control device 300, and a battery pack 100 may be provided inside the vehicle. The driving device 200 may be a motor, etc. The control device 300 is used to control the battery pack 100 to power the driving device 200. For example, the battery pack 100 may be provided at the bottom, front, or rear of the vehicle. The battery pack 100 may be used to power other devices in the vehicle. For example, the battery pack 100 may be used as an operating power source for the vehicle and for the circuit system of the vehicle, for example, for starting, navigating, and meeting the working power requirements of the vehicle during operation. In another example of the present invention, the battery pack 100 may not only be used as an operating power source for the vehicle, but may also be used as a driving power source for the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0075] Referring to Figures 2 and 3, the battery 100 includes a heat exchange assembly 40 and a plurality of battery cells 20, and the battery cells 20 are used to be accommodated in the heat exchange assembly 40. The heat exchange assembly 40 is formed with a mounting position for assembling the battery cells 20, and the heat exchange assembly 40 can adopt a variety of structures. In some embodiments, the heat exchange assembly 40 may include a first plate 41, a second plate 42, and a third plate 43, and the second plate 42 and the third plate 43 are located on both sides of the first plate 41 in the first direction. The first plate 41 and the second plate 42 form a first flow channel 4a, and the first plate 41 and the third plate 43 form a second flow channel 4b. The first flow channel 4a has a first inlet 421, and the second flow channel 4b has a second inlet 431. The first inlet 421 and the second inlet 431 are arranged independently of each other.

[0076] In the battery 100, multiple battery cells 20 can be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to a combination of series and parallel connections within the multiple battery cells 20. Multiple battery cells 20 can be directly connected in series, in parallel, or in a hybrid configuration, and then the entire structure of the multiple battery cells 20 is housed within the heat exchange assembly 40. Alternatively, the battery 100 can be constructed by first connecting multiple battery cells 20 in series, in parallel, or in a hybrid configuration to form a battery module. The multiple battery modules are then connected in series, in parallel, or in a hybrid configuration to form a single structure, which is then housed within the heat exchange assembly 40. The battery 100 may also include other structures, such as a busbar assembly for electrically connecting the multiple battery cells 20.

[0077] Please refer to Figure 4. In some examples, a heat exchange component 40 is disclosed, including at least two flow channels, including a first flow channel 4a and a second flow channel 4b. The first flow channel 4a is provided with a first inlet 421, and the second flow channel 4b is provided with a second inlet 431. The first inlet 421 and the second inlet 431 are provided independently of each other.

[0078] The first flow channel 4a and the second flow channel 4b can be used to input heat exchange medium respectively. The first flow channel 4a and the second flow channel 4b can be independent of each other, wherein the heat exchange medium can enter the first flow channel 4a and the second flow channel 4b through the first inlet 421 and the second inlet 431 respectively, and flow along the preset path of the first flow channel 4a and the second flow channel 4b.

[0079] Since different battery cells 20 can be installed at the positions corresponding to the first flow channel 4a and the second flow channel 4b when installing the battery cells 20, so that the first flow channel 4a is used for heat exchange with at least one battery cell 20, and the second flow channel 4b is used for heat exchange with at least another battery cell 20, the first flow channel 4a and the second flow channel 4b can respectively correspond to different battery cells 20, or correspond to battery packs formed by different battery cell arrangements, so that the first flow channel 4a and the second flow channel 4b can respectively achieve independent thermal control of the battery cells 20 or battery packs in the corresponding areas. For the convenience of description, the following is an example in which battery packs are installed at the corresponding positions of the first flow channel 4a and the second flow channel 4b. The corresponding position of the first flow channel 4a forms an installation position for installing a battery pack, and the corresponding position of the second flow channel 4b forms another installation position for installing a battery pack, so that the two installation positions can independently install battery packs while enabling the two installation positions to perform thermal control independently of each other.

[0080] Since the first inlet 421 and the second inlet 431 are arranged independently of each other, when the heat exchange medium is input into the heat exchange component 40, it can be input through the first inlet 421 and the second inlet 431 respectively, so that the battery groups at the corresponding positions of the first flow channel 4a and the second flow channel 4b can respectively perform heat exchange, so that the battery groups at the corresponding positions of the first flow channel 4a and the second flow channel 4b can respectively perform thermal control.

[0081] In some cases, in order to achieve thermal control of multiple battery packs, a heat exchange medium circulation pipeline is set outside the battery pack so that the heat exchange medium flows through multiple battery packs along the same pipeline, resulting in a higher heat content of the heat exchange medium near the input end of the pipeline and a lower heat content of the heat exchange medium near the output end of the pipeline, resulting in low heat exchange efficiency of the heat exchange medium near the output end of the pipeline. The higher heat content mentioned in this example refers to a higher temperature difference between the preset operating temperature of the heat exchange medium and the battery cell. Taking the preset operating temperature of the battery cell as the first temperature as an example, the higher heat content of the heat exchange medium means that the difference between the temperature of the heat exchange medium and the first temperature is larger, and the lower heat content of the heat exchange medium means that the difference between the temperature of the heat exchange medium and the first temperature is reduced. In order to achieve heat exchange between the heat exchange medium and the battery cell, without considering other factors, the greater the temperature difference between the heat exchange medium and the corresponding battery cell, the better the heat exchange effect between the heat exchange device and the corresponding battery cell.

[0082] In this example, the first flow channel 4a and the second flow channel 4b are set up independently of each other, so that the first flow channel 4a and the second flow channel 4b correspond to different battery groups respectively, so that different battery groups can perform heat exchange separately. Since heat will not accumulate between the first flow channel 4a and the second flow channel 4b, the first flow channel 4a and the second flow channel 4b can be used for thermal control of the corresponding battery groups respectively, so that there is no mutual accumulation and influence of heat between different battery groups. Moreover, the first flow channel 4a and the second flow channel 4b can also realize independent thermal control of different battery groups, so that the first flow channel 4a and the second flow channel 4b can perform different thermal control according to the heat exchange requirements of the target battery group for heat exchange. Since the first flow channel 4a and the second flow channel 4b can input heat exchange medium through the first inlet 421 and the second inlet 431 respectively, the first flow channel 4a and the second flow channel 4b can have different heat exchange effects by controlling the amount or flow rate of the heat exchange medium input to the first flow channel 4a and the second flow channel 4b, and then the amount or flow rate of the heat exchange medium input to the first flow channel 4a and the second flow channel 4b can be adaptively adjusted according to the heat exchange requirements of different battery packs to achieve different thermal control of the battery packs at the corresponding positions of the first flow channel 4a and the second flow channel 4b, so as to improve the flexibility and rationality of the thermal control of the battery packs at the corresponding positions of the first flow channel 4a and the second flow channel 4b.

[0083] For the convenience of description, the following is an example in which the first flow channel 4a corresponds to the first battery group and the second flow channel 4b corresponds to the second battery group, so that the first flow channel 4a position of the heat exchange component 40 performs heat exchange with the first battery group, and the second flow channel 4b position of the heat exchange component 40 performs heat exchange with the second battery group.

[0084] The heat exchange medium described in this example can be water, transformer oil or other fluids that can achieve heat exchange.

[0085] In some examples, the first flow channel 4 a and the second flow channel 4 b are formed by two pipes disposed inside the heat exchange component 40 .

[0086] In some examples, a through hole is opened in the heat exchange component 40, and the first flow channel 4a and the second flow channel 4b are formed by the through hole.

[0087] In some examples, the heat exchange assembly 40 is composed of two pipes, and a first flow channel 4a and a second flow channel 4b are formed inside the two pipes respectively.

[0088] In some examples, the first flow channel 4a further includes a first outlet 412, and the second flow channel 4b further includes a second outlet 415. The first outlet 412 and the second outlet 415 are configured independently of each other. Since the first outlet 412 and the second outlet 415 are independently provided, the heat exchange medium output from the first flow channel 4a and the heat exchange medium output from the second flow channel 4b can be output separately, thereby facilitating the design of the outlet positions of the first flow channel 4a and the second flow channel 4b as needed, thereby improving the flexibility of the flow path design.

[0089] In some examples, the first flow channel 4a further includes a first outlet 412, and the second flow channel 4b further includes a second outlet 415. The first outlet 412 and the second outlet 415 are configured as an integrated arrangement. By integrating the first outlet 412 and the second outlet 415, the centralized output of the heat exchange medium can be facilitated, thereby simplifying the design of the output pipeline.

[0090] Referring to Figure 5, in some examples, the heat exchange assembly 40 includes a first plate 41 and a second plate 42. The second plate 42 is disposed adjacent to and at an angle to the first plate 41. A first diverter channel 5b is formed within the first plate 41, and a second diverter channel 5a is formed within the second plate 42. The first diverter channel 5b and the second diverter channel 5a are connected to form a first flow channel 4a. In this example, the first and second plates 41, 42 are generally plate-shaped structures and are disposed at an angle to conform to the outer contour of the first battery pack. The first and second plates 41, 42 can respectively correspond to two adjacent surfaces of the first battery pack, so that the first and second plates 41, 42 are respectively used to exchange heat with the two adjacent surfaces of the first battery pack, thereby improving heat exchange efficiency.

[0091] In this example, a first branch channel 5b is formed in the first plate 41, and a second branch channel 5a is formed in the second plate 42. The first branch channel 5b and the second branch channel 5a are connected to each other to form a first channel 4a, so that the first branch channel 5b corresponds to one surface of the first battery pack, and the second branch channel 5a corresponds to the other surface of the first battery pack, thereby realizing heat exchange between different parts of the first battery pack.

[0092] In some examples, the heat exchange assembly 40 also includes a third plate 43, which is adjacent to the first plate 41 and is arranged at an angle to the first plate 41. A third branch channel 5d is also formed in the first plate 41, and a fourth branch channel 5c is formed in the third plate 43. The third branch channel 5d and the fourth branch channel 5c are connected to form a second channel 4b.

[0093] The first plate 41 and the third plate 43 are plate-shaped structures as a whole, and the first plate 41 and the third plate 43 are set at an angle to adapt to the outer contour of the second battery pack. The first plate 41 and the third plate 43 can respectively correspond to two adjacent surfaces of the second battery pack, so that the first plate 41 and the third plate 43 are respectively used to exchange heat with the two adjacent surfaces of the second battery pack to improve the heat exchange efficiency.

[0094] In this example, a third branch channel 5d is formed in the first plate 41, and a fourth branch channel 5c is formed in the third plate 43. The third branch channel 5d and the fourth branch channel 5c are interconnected to form a second channel 4b, so that the third branch channel 5d corresponds to one surface of the second battery pack, and the fourth branch channel 5c corresponds to the other surface of the second battery pack, thereby realizing heat exchange between different parts of the second battery pack.

[0095] In some examples, the heat exchange assembly 40 is used in an electrical device 1000. The electrical device 1000 is provided with a battery 100, and the battery 100 may further include a substrate 10. The heat exchange assembly 40 may include the first plate 41 and the second plate 42 described in any of the above examples. The first plate 41 is fixedly connected to the substrate 10. The electrical device may further include a mounting member 11. The substrate 10 is used to be mounted with the mounting member 11, so that the mounting member 11 serves as an intermediate connector between the substrate 10 and the electrical device 1000, thereby achieving overall fixation of the battery 100 on the electrical device 1000.

[0096] In some examples, the third plate 43 is disposed opposite the second plate 42. Furthermore, the first and second battery packs can be arranged side by side on either side of the first plate 41 on the heat exchange assembly 40. In some examples, the third plate 43 and the second plate 42 are both disposed on the same side of the first plate 41. The third and second plates 43, 42 can also be arranged in other ways to determine the specific positions of the first flow channel 4a and the second flow channel 4b according to the layout requirements of the battery packs.

[0097] In some examples, the first inlet 421 is located on the second plate 42, and the first outlet 412 is located on the first plate 41. The heat exchange medium enters the first flow channel 4a through the first inlet 421 on the second plate 42, flows along the second branch channel 5a into the first branch channel 5b, and is output to the outside of the heat exchange assembly 40 through the first outlet 412. Because the first inlet 421 and the first outlet 412 are located on the second plate 42 and the first plate 41, respectively, the heat exchange medium needs to flow through the second plate 42 and the first plate 41, thereby extending the flow path of the first flow channel 4a, allowing the heat exchange medium to fully exchange heat with the first battery pack, thereby improving the use efficiency of the heat exchange medium.

[0098] In some examples, the second inlet 431 is located on the third plate 43, and the second outlet 415 is located on the first plate 41. When the heat exchange medium enters the second flow channel 4b, it enters the second flow channel 4b through the second inlet 431 on the third plate 43, flows along the fourth branch channel 5c into the third branch channel 5d, and is output to the outside of the heat exchange assembly 40 through the second outlet 415. Because the second inlet 431 and the second outlet 415 are located on the third plate 43 and the first plate 41, respectively, the heat exchange medium needs to flow through the third plate 43 and the first plate 41, thereby extending the flow path of the second flow channel 4b, allowing the heat exchange medium to fully exchange heat with the second battery pack, thereby improving the use efficiency of the heat exchange medium.

[0099] In some examples, the first inlet 421 is located at an end of the second plate 42 away from the first plate 41. After the heat exchange medium enters the first inlet 421, it needs to flow along the second branch channel 5a toward the first branch channel 5b. Since the first inlet 421 is set away from the first plate 41, the flow path of the heat exchange medium in the second plate 42 is extended, thereby enabling the heat exchange medium to fully exchange heat with the corresponding first battery group to fully utilize the heat of the heat exchange medium.

[0100] In some examples, one end of the second plate 42 is connected to the first plate 41, and the other end extends above the first plate 41. The first inlet 421 is provided at the upper end of the second plate 42 so that after the heat exchange medium enters the second plate 42, it can flow toward the first branch channel 5b of the first plate 41 under the action of gravity, thereby accelerating the input efficiency of the heat exchange medium.

[0101] In some examples, the second inlet 431 is located at an end of the third plate 43 away from the first plate 41. After the heat exchange medium enters the second inlet 431 and flows along the fourth branch channel 5c toward the third branch channel 5d, the second inlet 431 is located away from the first plate 41, thereby extending the flow path of the heat exchange medium within the third plate 43. This can further extend the heat exchange time between the heat exchange medium and the second battery pack, thereby improving the use efficiency of the heat exchange medium.

[0102] In some examples, one end of the third plate 43 is connected to the first plate 41, and the other end extends above the first plate 41. The second inlet 431 is provided at the upper end of the third plate 43 so that after the heat exchange medium enters the third plate 43, it can flow toward the third branch channel 5d of the first plate 41 under the action of gravity, thereby accelerating the input efficiency of the heat exchange medium.

[0103] Please refer to Figure 5. In some examples, the first branch channel 5b and the second branch channel 5a are connected at the intersection of the angle between the first plate 41 and the second plate 42. The first branch channel 5b extends toward the second plate 42 and is connected to the second branch channel 5a, so that the connection between the first branch channel 5b and the second branch channel 5a is located at the intersection of the angle between the first plate 41 and the second plate 42. Therefore, there is no need to separately set a connection module for connecting the first branch channel 5b and the second branch channel 5a outside the heat exchange component 40, so as to simplify the structure, reduce the layout of external pipelines, and help improve the compactness and stability of the overall structure.

[0104] In some examples, the third branch channel 5d and the fourth branch channel 5c are connected at the angle between the first plate 41 and the third plate 43. The third branch channel 5d extends toward the third plate 43 and is connected to the fourth branch channel 5c, so that the connection between the third branch channel 5d and the fourth branch channel 5c is located at the intersection of the angle between the first plate 41 and the third plate 43. Therefore, there is no need to separately provide a connection module for connecting the third branch channel 5d and the fourth branch channel 5c outside the heat exchange assembly 40, which facilitates the simplification of the structure, reduces the layout of external pipelines, and helps to improve the compactness and stability of the overall structure.

[0105] In some examples, the first plate 41 is provided as a split body, and the split first plate 41 includes a first portion 411 and a second portion 414, wherein the first portion 411 and the second portion 414 are used to arrange the first shunt channel 5b and the third shunt channel 5d, respectively. In this example, the first plate 41 can be provided at the bottom of the battery pack, wherein the first portion 411 is provided at the bottom of the first battery pack, and the second portion 414 is provided at the bottom of the second battery pack, so that the first shunt channel 5b and the third shunt channel 5d correspond to the first battery pack and the second battery pack, respectively, thereby improving the flexibility of battery pack installation. Since the first portion 411 and the second portion 414 are provided as separate bodies, it is convenient to drill holes or lay pipes in the first portion 411 and the second portion 414 to facilitate the formation of the first shunt channel 5b and the second shunt channel 5a.

[0106] Referring to FIG. 4 , in some examples, the first portion 411 and the second portion 414 are connected and fixed along a first direction 4A. The first portion 411 and the second portion 414 of the first plate 41 are arranged along the first direction 4A and are connected and fixed to each other so that the first portion 411 and the second portion 414 form a compact plate-like structure. By connecting and fixing the first portion 411 and the second portion 414 to each other, the first portion 411 and the second portion 414 form a whole. This facilitates the installation and positioning of the first and second battery packs during installation, and simultaneously reduces the installation space required for the overall structure on the electrical device 1000, making the overall structure more compact and stable.

[0107] In some examples, the second plate 42 and the third plate 43 are located on either side of the first plate 41 along the first direction 4A, and the second plate 42 is connected to the first portion 411, and the third plate 43 is connected to the second portion 414. In this example, the second plate 42 and the third plate 43 are respectively arranged on either side of the first plate 41 so that the second plate 42 and the third plate 43 are arranged opposite each other, the first battery group and the second battery group are arranged between the second plate 42 and the third plate 43, and the first plate 41 can be used to be arranged below the first battery group and the second battery group, thereby making the overall structure compact. Because the second plate 42 is connected to the first portion 411 of the first plate 41, the first flow channel 4a can be formed on the second plate 42 and the first plate 41, and the third plate 43 is connected to the second portion 414 of the first plate 41, and the second flow channel 4b can be formed on the third plate 43 and the first plate 41, thereby facilitating the layout of the first flow channel 4a and the second flow channel 4b.

[0108] In some examples, the first portion 411 and the second plate 42 are integrally formed. After the forming process, the integral structure is bent so that the first portion 411 is disposed at an angle to the second plate 42. By adopting an integral structure, the corresponding first and second flow channels 5b, 5a can be easily formed in the first portion 411 and the second plate 42, eliminating the need for a separate adapter for connecting the first and second flow channels 5b, 5a. This also reduces the possibility of water leakage at the connection between the first and second flow channels 5b, 5a.

[0109] In some examples, the second portion 414 is integrally formed with the third plate 43. The molding method of the second portion 414 and the third plate 43 in this example can be the same as the molding method of the first portion 411 and the second plate 42, or can be different from the molding method of the first portion 411 and the second plate 42. In some examples, the second portion 414 and the third plate 43 are integrally formed. After the molding is completed, the overall structure is bent so that the second portion 414 and the third plate 43 are arranged at an angle. By adopting an integrally arranged structure, it is convenient to form the corresponding third branch channel 5d and the fourth branch channel 5c in the second portion 414 and the third plate 43, and thus there is no need to separately set up an adapter for connecting the third branch channel 5d and the fourth branch channel 5c. At the same time, the risk of water leakage caused by the poor sealing of the connector when a connector is used at the connection between the third branch channel 5d and the fourth branch channel 5c can be reduced.

[0110] In some examples, the first and third runners 5b, 5d are arranged along the first direction 4A. In this example, the first and third runners 5b, 5d correspond to the first portion 411 and the second portion 414 of the first plate 41. By arranging the first and third runners 5b, 5d along the first direction 4A, the first runner 5b can act on the bottom of the first battery pack, and the second runner 5a can act on the bottom of the second battery pack. The first and second battery packs can be arranged along the first direction 4A, making the overall product structure more compact and fully utilizing the internal space of the heat exchange assembly 40.

[0111] In some examples, the first outlet 412 and the first inlet 421 are located at opposite ends in the second direction 4B. The heat exchange medium enters the first flow channel 4a through the first inlet 421 and flows along the first flow channel 4a to the first outlet 412. Because the first outlet 412 and the first inlet 421 are located at opposite ends in the second direction 4B, the flow path of the heat exchange medium in the first flow channel 4a can be extended, thereby improving the heat utilization efficiency of the heat exchange medium. By locating the first outlet 412 and the first inlet 421 at opposite ends in the second direction 4B, sufficient space is provided when laying out the first flow channel 4a, facilitating the desired location and direction of the first flow channel 4a, thereby aligning the first flow channel 4a with the location of the first battery pack. In some examples, the first inlet 421 is located at the end of the second plate 42 away from the first plate 41, and the first outlet 412 is located at the end of the first portion 411 of the first plate 41 away from the second plate 42, thereby extending the flow path of the first flow channel 4a.

[0112] In some examples, the second outlet 415 and the second inlet 431 are located at opposite ends in the second direction 4B, where the second direction 4B intersects the first direction 4A. The heat exchange medium enters the second flow channel 4b through the second inlet 431 and flows along the second flow channel 4b to the second outlet 415. Because the second outlet 415 and the second inlet 431 are located at opposite ends in the second direction 4B, the flow path of the heat exchange medium within the second flow channel 4b can be extended, thereby improving the heat utilization efficiency of the heat exchange medium. By locating the second outlet 415 and the second inlet 431 at opposite ends in the second direction 4B, sufficient space is provided when laying out the second flow channel 4b, facilitating the desired positioning and extension of the second flow channel 4b, thereby aligning the second flow channel 4b with the second battery pack. In some examples, the second outlet 415 is located at the end of the second portion 414 of the first plate 41 away from the third plate 43, and the second inlet 431 is located at the end of the third plate 43 away from the first plate 41, thereby extending the length of the second flow path.

[0113] In some examples, the heat exchange assembly 40 further includes a first input connector 422 and a second input connector 432, which are mounted on the first inlet 421 and the second inlet 431, respectively. The provision of the first input connector 422 and the second input connector 432 facilitates connecting the first inlet 421 and the second inlet 431 to input pipelines for the heat exchange medium, thereby facilitating access to the heat exchange medium. In some examples, the first input connector 422 and the second input connector 432 may be valves or connecting pipes to facilitate connecting the first inlet 421 and the second inlet 431 to external pipelines, respectively.

[0114] In some examples, the heat exchange assembly 40 further includes an input manifold 45, which includes a water inlet and multiple water outlets connected to the water inlet, two of the multiple water outlets being respectively connected to the first input connector 422 and the second input connector 432. The input manifold 45 is used to connect to an external heat exchange medium pipeline, so that the input manifold 45 can serve as an intermediate adapter between the external heat exchange medium pipeline and the first input connector 422 and the second input connector 432, thereby achieving centralized input of the heat exchange medium.

[0115] Since the first flow channel 4a and the second flow channel 4b can be centrally input through the input collecting member 45, the external input pipeline can be simplified to improve the integration of the external input pipeline and facilitate the centralized input of the heat exchange medium.

[0116] In some examples, the input manifold 45 is provided with a flow control switch, which is used to control the rate at which the heat exchange medium enters the first flow channel 4a and the second flow channel 4b. In this example, the flow control switch is used to control the output of the water outlet of the input manifold 45, thereby controlling the flow rate of the heat exchange medium in the first flow channel 4a and the second flow channel 4b. The flow control switch can be a valve or other structure that can control the flow rate and flow velocity.

[0117] In this example, a flow control switch is used to control the rate of the heat exchange medium in the first flow channel 4a and the second flow channel 4b so that the heat exchange medium in the first flow channel 4a and the second flow channel 4b is adapted to the heat required by the corresponding first battery group and the second battery group, thereby realizing zoned thermal control of battery groups in different areas.

[0118] In some examples, the flow control switch is used to control the rate at which the heat exchange medium enters the first flow channel 4a to be greater than the rate at which the heat exchange medium enters the second flow channel 4b. In this example, by ensuring that the heat exchange medium enters the first flow channel 4a at a greater rate than the rate at which the heat exchange medium enters the second flow channel 4b, the heat volume of the heat exchange medium in the first flow channel 4a is greater than that in the second flow channel 4b. This increases the heat exchange efficiency of the first battery pack in the first flow channel 4a compared to the heat exchange efficiency of the second battery pack in the second flow channel 4b, thereby achieving zoned thermal management of the first and second battery packs.

[0119] In some examples, the first outlet 412 and the second outlet 415 are configured to be independently arranged on the first plate 41, and the heat exchange assembly 40 also includes a first output connector 413 and a second output connector 416, which are respectively connected to the first outlet 412 and the second outlet 415.

[0120] The first output connector 413 serves as an intermediate connector between the first outlet 412 and the external pipeline, while the second output connector 416 serves as an intermediate connector between the second outlet 415 and the external pipeline, thereby enabling the first outlet 412 and the second outlet 415 to connect to the external pipeline. In this example, the provision of the first output connector 413 and the second output connector 416 facilitates the connection of the corresponding first flow channel 4a and the second flow channel 4b to the external pipeline, thereby facilitating the output of the heat exchange medium.

[0121] In some examples, the heat exchange assembly 40 further includes an output manifold 417, which includes multiple water inlets and water outlets connected to the multiple water inlets. Two of the multiple water inlets are respectively connected to the first output connector 413 and the second output connector 416. The manifold is used to connect to an external heat exchange medium pipeline, so that the output manifold 417 can serve as an intermediate adapter between the external heat exchange medium pipeline and the first output connector 413 and the second output connector 416, thereby achieving centralized output of the heat exchange medium.

[0122] Since the first flow channel 4a and the second flow channel 4b can be collectively output through the output collecting member 417, the external output pipeline can be simplified to improve the integration of the external output pipeline and facilitate the centralized output of the heat exchange medium.

[0123] In some examples, the heat exchange component 40 also includes a first input connector 422 and a second input connector 432, which are respectively installed at the first inlet 421 and the second inlet 431, and the first outlet 412 and the second outlet 415 are configured to be independently arranged on the first plate 41. The heat exchange component 40 also includes a first output connector 413 and a second output connector 416, which are respectively connected to the first outlet 412 and the second outlet 415, and the first input connector 422, the second input connector 432, the first output connector 413 and the second output connector 416 are all located at the same end of the heat exchange component 40 along the third direction 4C, and the third direction 4C is perpendicular to the first direction 4A and the second direction 4B.

[0124] By locating the first input connector 422, the second input connector 432, the first output connector 413 and the second output connector 416 at the same end of the heat exchange component 40 along the third direction 4C, multiple connector modules are located on the same side of the heat exchange component 40, thereby facilitating the layout of the pipelines. At the same time, the pipelines only occupy the space on the same side of the heat exchange component 40 to reduce interference with the battery pack.

[0125] In some examples, the heat exchange assembly 40 has a first end and a second end disposed opposite each other along a third direction 4C, and at least one of the first and second ends of the heat exchange assembly 40 is provided with a limit member 44. The limit member 44 is disposed at the end of the heat exchange assembly 40 in the third direction 4C to reduce the possibility of movement of the battery pack along the third direction 4C, thereby limiting the position of the battery pack. In this example, there can be one limit member 44, which can be disposed on any one of the first plate 41, the second plate 42, and the third plate 43. In some examples, there can be multiple limit members 44, which can all be disposed on any one of the first plate 41, the second plate 42, and the third plate 43, or at least one limit member 44 can be disposed on each of the second plate 42 and the third plate 43.

[0126] In some examples, the first flow channel 4a and the second flow channel 4b each include multiple sub-flow channels connected in parallel, and the first flow channel 4a and the second flow channel 4b are configured to differ in at least one of the number of sub-flow channels, the total width of the sub-flow channels, and the total area of ​​the sub-flow channels. The sub-flow channels of the first flow channel 4a and the second flow channel 4b are used to expand the coverage area of ​​the corresponding first flow channel 4a and the second flow channel 4b, so that the heat exchange medium can act on different parts of the battery pack, thereby achieving thermal management of different parts of the battery pack. By adjusting parameters such as the number of sub-flow channels, the total width of the sub-flow channels, and the total area of ​​the sub-flow channels, the heat at the corresponding position of the heat exchange component 40 is controlled, so that the heat exchange component 40 can be adapted to the battery pack and temperature gradient control can be achieved at different positions.

[0127] Referring to Figures 1 to 3, the present application also proposes an example of a battery 100, which includes a battery cell 20 and a heat exchange component 40 as described in any of the above examples. The heat exchange component 40 is used for heat exchange with the battery cell 20.

[0128] The battery cells 20 are mounted on the heat exchange assembly 40 so that the heat exchange assembly 40 can be used to perform heat exchange with the battery cells 20 , thereby achieving thermal management of the battery cells 20 and reducing the possibility of thermal runaway of the battery cells 20 .

[0129] In the heat exchange component 40 in this example, battery cells 20 are installed at positions corresponding to the first flow channel 4a and positions corresponding to the second flow channel 4b, respectively, so that the positions corresponding to the first flow channel 4a and the positions corresponding to the second flow channel 4b are respectively used for zoned thermal management of different battery cells 20, and then zoned thermal control is achieved as needed, so that the heat exchange component 40 can adapt to the heat requirements of the corresponding positions, thereby reducing the possibility of thermal balance not being achieved when the heat requirements of different positions inside the battery 100 are different.

[0130] Referring to Figures 4 and 5 , in some examples, the heat exchange assembly 40 includes a first plate 41 and a second plate 42. The second plate 42 is disposed adjacent to and at an angle to the first plate 41. A first branch channel 5b is formed in the first plate 41, and a second branch channel 5a is formed in the second plate 42. The first branch channel 5b and the second branch channel 5a are connected to form a first flow channel 4a. The battery 100 also includes a substrate 10, to which the first plate 41 is fixedly connected. In this example, the substrate 10 is used to support and position the first plate 41, thereby constraining the heat exchange assembly 40 to a predetermined position.

[0131] When installing the battery 100 , the substrate 10 can serve as an intermediate connector between the heat exchange component 40 and the external structure to achieve docking between the heat exchange component 40 and the external structure.

[0132] In some examples, the first plate 41 and the base plate 10 are fixed to each other by means of clipping, welding or threaded connection. When the first plate 41 and the base plate 10 are connected and fixed to each other, the relative position of the heat exchange component 40 on the base plate 10 is also determined.

[0133] In some examples, the first outlet 412 and the first inlet 421 of the heat exchange assembly 40 are located at opposite ends in the second direction 4B, and / or the second outlet 415 and the second inlet 431 are located at opposite ends in the second direction 4B. The second direction 4B intersects the first direction 4A. The first branch channel 5b and the third branch channel 5d extend along the first direction 4A to form two mounting positions, each of which contains at least one battery cell 20. The first branch channel 5b and the second branch channel 5a correspond to two mounting positions, respectively, so that at least a first battery pack and a second battery pack can be mounted on the heat exchange assembly 40. The first battery pack or the second battery pack has at least one battery cell 20. The first flow channel 4a and the second flow channel 4b are used to respectively control the thermal performance of the first and second battery packs, thereby achieving zoned thermal management of the two battery packs.

[0134] In some examples, battery packs are placed on two mounting positions, each configured to be formed by a plurality of battery cells 20 arranged along a third direction 4C. In this example, the two mounting positions correspond to a first battery pack and a second battery pack, wherein the first battery pack and the second battery pack are both formed by a plurality of battery cells 20 arranged along a third direction 4C, and thermal control is performed on the first battery pack and the second battery pack respectively through the first flow channel 4a and the second flow channel 4b. Because the first flow channel 4a and the second flow channel 4b are independent of each other, zoned thermal control can be achieved at the corresponding positions of the first battery pack and the second battery pack, so that the heat delivered to the first battery pack and the second battery pack by the heat exchange component 40 is adapted to the heat required by the corresponding mounting area, thereby better achieving thermal control.

[0135] Please refer to Figures 2 and 3. In some examples, the battery 100 also includes an end plate 30, which is located at the end of the battery pack along the third direction (i.e., the 2a-2a direction in Figure 2), and the end plate 30 is located between the battery pack and the limiter 44. The end plate 30 is used to block the end of the battery pack in the third direction to reduce the possibility of displacement of the battery pack along the third direction, thereby improving the stability of the battery pack. The position of the battery pack in the first direction 4A in this example is limited by the second plate 42 and the third plate 43. The displacement of the battery pack in the third direction is limited by the end plate 30, and the battery pack is confined to the two mounting positions of the heat exchange assembly 40 to improve the overall stability of the battery 100. In this example, the 2a-2 direction in Figure 2 can be parallel to the above-mentioned third direction 1C direction.

[0136] In some examples, a structure for fixing the end plate 30 is provided on the battery 100. For example, the end plate 30 can be connected and fixed to the first plate 41 or the base plate 10 by screw connection, clamping, or pinning.

[0137] Referring to Figures 1 to 7 , in some examples, a battery 100 for an electric device 1000 is disclosed. The battery 100 includes a heat exchange assembly 40 and a battery cell 20 mounted on the battery assembly. The heat exchange assembly 40 is configured to exchange heat with the battery cell 20 to achieve thermal control of the battery cell 20. The heat exchange assembly 40 includes a first flow channel 4a and a second flow channel 4b. The first flow channel 4a and the second flow channel 4b are independently arranged so that positions corresponding to the first flow channel 4a and the second flow channel 4b can be used to mount a first battery pack and a second battery pack, respectively. The first flow channel 4a exchanges heat with the corresponding first battery pack, and the second flow channel 4b exchanges heat with the corresponding second battery pack, to achieve independent thermal control of the first and second battery packs. Furthermore, a heat exchange medium is provided to the corresponding positions of the first and second battery packs based on their heat requirements, so that the heat provided by the heat exchange medium matches the heat requirements of the corresponding positions, thereby achieving zoned temperature control of the corresponding positions and reducing the possibility of thermal runaway caused by unreasonable heat distribution in the first and second battery packs. In this example, the first inlet 421 of the first flow channel 4a and the second inlet 431 of the second flow channel 4b are located at the upper end of the heat exchange assembly 40, allowing the heat exchange medium to flow toward the outlet under the action of gravity, thereby reducing the heat exchange medium's transport resistance and improving the heat exchange medium's transport efficiency, thereby rapidly transporting heat to the corresponding first and second battery packs. In this example, the first inlet 421 and the second inlet 431 are respectively provided with a first input connector 422 and a second input connector 432. The heat exchange medium is transported to the first and second input connectors 422 and 432 through the input manifold 45, achieving centralized input of the heat exchange medium. This simplifies the heat exchange medium input piping on the electrical device 1000 and fully utilizes the internal space of the electrical device 1000. In this example, the flow parameters of the first flow channel 4a and the second flow channel 4b are different. The flow parameters include but are not limited to the rate of the input heat exchange medium, the number of sub-flow channels, the total width of the sub-flow channels, and the total area of ​​the sub-flow channels. By controlling the flow parameters of the first flow channel 4a and the second flow channel 4b, the heat of the heat exchange medium transported by the first flow channel 4a and the second flow channel 4b can be adjusted, and then the total amount of heat transported to the first battery group or the second battery group can be determined according to specific needs, so that the heat corresponds to the heat requirements of the first battery group and the second battery group.
