[0003] Batteries are widely applied in electronic devices such as mobile phones, notebook computers, battery vehicles, electric vehicles, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes and electric tools.

[0004] In the development of battery technology, how to improve the cycle performance of batteries is an important research direction in battery technology.

Summary of the Invention

[0005] This application provides a thermal management member, a battery and a power consumption device that can improve the cycle performance of the battery.

[0006] According to a first aspect, this application provides a thermal management member, which includes a housing and a support member. An accommodation space is provided inside the housing, and the housing includes a first wall and a second wall located on both sides of the accommodation space respectively. The support member is installed in the accommodation space and supported between the first wall and the second wall, and the support member is configured to be deformable when receiving the pressing of the first wall.

[0007] The supporting member can support the first wall and the second wall and reduce the risk of collapse of the first wall or the second wall. The supporting member is deformable when the first wall is pressed, so that when expansion occurs during the charge and discharge cycle of the battery cell, the first wall deforms along with the deformation of the supporting member under the pressing action of the battery cell, extrudes and secures space due to the expansion of the battery cell, reduces the acting force between the battery cell and the thermal management member, and reduces the reduction range of the heat exchange area between the battery cell and the thermal management member, thereby improving the cycle performance of the battery cell.

[0008] In some embodiments, the first wall and the second wall are installed opposite to each other along the first direction, and the supporting member includes an inclined portion at least partially installed inclined with respect to the first direction.

[0009] When the thermal management member receives a pressing force along the first direction of the battery cell, the inclined portion can deform, and the size of the deformed inclined portion along the first direction is compressed, thereby reducing the acting force between the battery cell and the thermal management member, so that the heat exchange area between the battery cell and the thermal management member meets the requirements and improves the cycle performance of the battery cell.

[0010] In some embodiments, a plurality of inclined portions are installed, and the plurality of inclined portions are arranged along a second direction perpendicular to the first direction.

[0011] By installing a plurality of inclined portions, the supporting force for the first wall and the second wall can be increased, and the risk of damage when the thermal management member receives a relatively large concentrated stress can be reduced.

[0012] In some embodiments, the directions in which two adjacent inclined portions incline are opposite, which can increase the resilience ability after the supporting member deforms, increase the contact area between the housing and the battery cell, and improve the thermal management ability of the thermal management member for the battery cell.

[0013] In some embodiments, a flow path is formed between adjacent inclined portions in the second direction.

[0014] The plurality of inclined portions can partition the accommodation space into a plurality of flow paths. When the heat exchange medium enters the accommodation space, the heat exchange medium can be divided into the plurality of flow paths, so that when the heat management member contacts the battery cell, the temperature of each part of the battery cell can be adjusted relatively uniformly.

[0015] In some embodiments, the support member includes a plurality of arch structures arranged along a second direction, and each arch structure includes two adjacent inclined portions.

[0016] The arch structure has relatively good elasticity, which enhances the resilience ability after the support member is deformed, further increases the contact area between the housing and the battery cell, and improves the heat management ability of the heat management member with respect to the battery cell.

[0017] In some embodiments, an end portion of the arch structure adjacent to the second wall along a first direction abuts against and is connected to the second wall.

[0018] The arch structure is connected to the second wall, which can increase the connection strength between the arch structure and the housing, reduce the risk of the support member swinging in the accommodation space, and improve the stability of the support member.

[0019] In some embodiments, the support member further includes a connecting portion that connects two adjacent inclined portions and abuts against the first wall.

[0020] The connecting portion can integrally connect the two inclined portions, increase the structural strength of the support member, the plurality of inclined portions form an entirety, increase the resilience ability after deforming in the first direction, and improve the heat management ability of the heat management member with respect to the battery cell. The connecting portion can increase the distance between the two inclined portions and increase the overcurrent area of the flow path surrounded by the connecting portion and the two inclined portions.

[0021] In some embodiments, the support member includes a plurality of arch structures arranged along a second direction, each arch structure includes two adjacent inclined portions, and adjacent arch structures are connected by a connecting portion.

[0022] Adjacent arch structures are connected by a connecting portion, which can increase the structural strength of the support member. The plurality of arch structures form an entirety, increasing the resilience after deformation in the first direction and improving the heat management ability of the heat management member for the battery cell. The connecting portion can increase the distance between two arch structures and increase the overcurrent area of the flow path surrounded by the connecting portion and the two arch structures.

[0023] In some embodiments, the connecting portion is welded to the first wall, and the arch structure is welded to the second wall.

[0024] The connecting portion and the first wall, and the arch structure and the second wall are all connected by welding, which can increase the connection fastening property between the support member and the housing, increase the supporting force of the support member on the first wall and the second wall, and reduce the risk of damage when the heat management member receives a relatively large concentrated stress. Moreover, the support member is connected to both the first wall and the second wall. The first wall covers the opening of the arch structure. Therefore, the arch structure and the first wall are peripherally arranged to form a flow path. The second wall covers the side away from the arch-shaped openings of the connecting portion and two adjacent inclined portions. Therefore, the connecting portion, the back sides of two adjacent arch structures, and the second wall are also peripherally arranged to form a flow path. Therefore, the support member, the first wall, and the second wall are peripherally arranged to form a plurality of mutually independent flow paths. When the heat exchange medium enters the accommodation space, the heat exchange medium can be divided into the plurality of flow paths, so that when the heat management member contacts the battery cell, the temperature of each part of the battery cell can be adjusted relatively uniformly.

[0025] In some embodiments, the material of the support member is an elastic material.

[0026] The support member is made of an elastic material, and the elastic material is easy to deform and has a high repulsive ability after deformation. Therefore, when the heat management member receives a pressing force along the first direction, the support member is relatively easy to deform, significantly reducing the acting force between the battery cell and the heat management member, and not only can the cycle performance of the battery cell be improved, but also the relatively good repulsive ability can further increase the contact area between the heat management member and the battery cell, and improve the heat management ability of the heat management member for the battery cell.

[0027] In some embodiments, the support member has a porous structure. Since the support member adopts a porous structure and there are relatively many voids due to the porous structure, it is easy to deform. Therefore, when the heat management member receives a pressing force along the first direction, the support member is relatively easy to deform, significantly reducing the acting force between the battery cell and the heat management member, and the cycle performance of the battery cell can be improved.

[0028] In some embodiments, a liquid inlet and a liquid outlet communicating with the accommodation space are provided in the housing. The heat exchange medium enters from the liquid inlet, flows through the accommodation space, and then exits from the liquid outlet.

[0029] In some embodiments, the accommodation space includes a first bus bar region and a second bus bar region. The liquid inlet communicates with the first bus bar region, and the liquid outlet communicates with the second bus bar region. The support member, the first wall, and the second wall surround to form a plurality of flow paths, and the plurality of flow paths are used to communicate the first bus bar region and the second bus bar region.

[0030] By providing the first bus bar region and the second bus bar region, if the plurality of flow paths are communicated with the first bus bar region and the second bus bar region, they can be communicated with the liquid inlet and the liquid outlet. Therefore, by providing one liquid inlet and one liquid outlet, a plurality of mutually independent flow paths can be communicated, so that the heat exchange medium can flow through all of the plurality of flow paths in the support member.

[0031] In some embodiments, the first bus bar region and the second bus bar region are located on both sides along the third direction of the support member.

[0032] The first bus bar region and the second bus bar region are installed on both sides along the third direction of the support member. Further, the heat exchange medium flows through a plurality of flow paths from the first bus bar region along the third direction and reaches the second bus bar region. The heat exchange medium generally flows through the entire support member along the third direction to perform heat exchange on the battery cell. The running path of the heat exchange medium is relatively flat, and the heat exchange effect is relatively high.

[0033] In some embodiments, the support member includes a main body portion and a partition portion protruding from one end of the main body portion along the third direction. The accommodation space further includes a third bus bar region. The third bus bar region is located on a side away from the partition portion of the main body portion. The first bus bar region and the second bus bar region are located on the same side facing the partition portion of the main body portion. And the partition portion is used to partition the first bus bar region and the second bus bar region. The plurality of flow paths include a first flow path and a second flow path. The first flow path is used to communicate the first bus bar region and the third bus bar region. The second flow path is used to communicate the second bus bar region and the third bus bar region.

[0034] The liquid inlet and the liquid outlet of the embodiment of the present application are located on the same side facing the partition portion of the main body portion. The distance between the liquid inlet and the liquid outlet is relatively close, which is convenient for laying pipes.

[0035] In some embodiments, the housing includes a first case and a second case. The first case and the second case are connected to enclose the accommodation space. The first case includes a first wall, and the second case includes a second wall.

[0036] In some embodiments, a first recess is provided on a side of the first case facing the second case, a second recess is provided on a side of the second case facing the first case, the accommodation space includes the first recess and the second recess, the bottom wall of the first recess is the first wall, and the bottom wall of the second recess is the second wall.

[0037] Both the first case and the second case are recessed outwardly, which can relatively increase the volume of the accommodation space, accommodate more heat exchange medium, and enhance the cooling effect on the battery cells.

[0038] According to a second aspect, the present application provides a battery, which includes a battery cell and the above-mentioned heat management member for heat exchange with the battery cell.

[0039] In some embodiments, there are a plurality of battery cells, and at least a part of the heat management member is located between adjacent battery cells. The heat management member can perform heat exchange with the battery cells on both sides thereof simultaneously, improving the heat exchange efficiency.

[0040] According to a third aspect, the present application provides a power consumption device, which includes the above-mentioned battery, and the battery is used to provide electrical energy.

It should be understood that the dimensions such as the thickness and aspect of various members in the embodiments of the present application shown in the drawings, and the dimensions such as the thickness and aspect of the entire integrated device are only exemplary descriptions and do not constitute any limitation to the present application.

[0048] "A plurality" as used in the present application refers to two or more (including two).

[0051] Batteries exhibit different electrical cycle performances at different ambient temperatures. When the ambient temperature is too high or too low, both will cause a decrease in the cycle performance of the battery, and ultimately lead to a shortening of its service life. In order to ensure the safety, stable performance, and good operation of new energy vehicles, it is necessary to perform effective thermal management on the battery to control the battery to always operate within an appropriate temperature range.

[0052] The inventor installs a thermal management member in the battery. The thermal management member can be used to perform heat exchange with the battery cells of the battery and perform effective thermal management on the battery, so as to operate the battery cells within an appropriate temperature range.

[0053] The inventor has discovered that during the charging and discharging process, the battery cells of the battery are prone to swelling. After swelling and deforming, the heat conduction area between the battery cells and the heat management member decreases, reducing the heat exchange efficiency and affecting the cycle life of the battery cells.

[0054] Based on the above considerations, as a result of intensive research, the inventor has designed a heat management member, installed a support member inside the housing of the heat management member, and the support member can deform when receiving pressure. In this way, the supporting force of the support member on the first wall and the second wall can be appropriately weakened, so that the heat management member can be correspondingly compressed and slightly deformed when the outer shape of the battery cell expands, thereby reducing the reduction range of the heat exchange area between the two and improving the cycle performance of the battery cell.

[0055] The battery cells described in the embodiments of the present application are applicable to batteries and power-consuming devices using the battery cells.

[0056] The power-consuming device may be a vehicle, a mobile phone, a portable device, a notebook computer, a steamship, a spacecraft, an electric toy, and an electric tool, etc. The vehicle may be a fuel-powered vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or a range extender vehicle, etc. The spacecraft includes airplanes, rockets, space shuttles, and spaceships, etc. The electric toy includes stationary or mobile electric toys, such as game machines, electric vehicle toys, electric steamship toys, and electric airplane toys, etc. The electric tool includes metal cutting electric tools, grinding electric tools, assembly electric tools, and railway electric tools, such as electric drills, electric grinders, electric wrenches, electric drivers, electric hammers, electric impact drills, concrete vibrators, and electric shears, etc. The embodiments of the present application do not particularly limit the above power-consuming devices.

[0057] In the following embodiments, for the sake of convenience of explanation, the case where the power-consuming device is a vehicle will be taken as an example for explanation.

[0058] FIG. 1 is a schematic structural diagram of a vehicle according to some embodiments of the present application.

[0059] As shown in FIG. 1, a battery 2 is installed inside the vehicle 1, and the battery 2 may be installed at the bottom, head, or tail of the vehicle 1. The battery 2 may be used for power supply of the vehicle 1. For example, the battery 2 may be used as an operating power source of the vehicle 1.

[0060] 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, for starting the vehicle 1, navigation, and power consumption requirements during driving.

[0061] In some embodiments of the present application, the battery 2 can not only be used as an operating power source of the vehicle 1, but also as a driving power source of the vehicle 1 to provide driving power to the vehicle 1 instead of gasoline or natural gas, or instead of a part of them.

[0062] FIG. 2 is a schematic exploded view of a battery according to some embodiments of the present application.

[0063] As shown in FIG. 2, the battery 2 includes a housing 5 and a battery cell (not shown), and the battery cell is housed inside the housing 5.

[0064] The housing 5 is used to accommodate battery cells, and the housing 5 may have various structures. In some embodiments, the housing 5 may include a first housing part 5a and a second housing part 5b. The first housing part 5a and the second housing part 5b may be overlapped with each other, and the first housing part 5a and the second housing part 5b together define an accommodation space 5c for accommodating battery cells. The second housing part 5b may have a hollow structure with one end open. The first housing part 5a may have a plate-like structure. The first housing part 5a is placed on the opening side of the second housing part 5b, thereby forming the housing 5 having the accommodation space 5c. Both the first housing part 5a and the second housing part 5b may have a hollow structure with one side open. The opening side of the first housing part 5a is placed on the opening side of the second housing part 5b to form the housing 5 having the accommodation space 5c. Of course, the first housing part 5a and the second housing part 5b may have various shapes, such as a cylindrical body, a rectangular parallelepiped, etc.

[0065] In order to improve the sealing performance after connecting the first housing part 5a and the second housing part 5b, a sealing material may be installed between the first housing part 5a and the second housing part 5b. For example, a sealant, a sealing ring, etc. may be installed.

[0066] Assuming that the first housing part 5a is placed on the top of the second housing part 5b, the first housing part 5a is also called an upper housing cover, and the second housing part 5b is also called a lower housing.

[0067] In the battery 2, the number of battery cells may be one or more. When there are multiple battery cells, the multiple battery cells may be connected in series, in parallel, or in series-parallel connection. Series-parallel connection means that there are both series connection and parallel connection among the multiple battery cells. The multiple battery cells may be directly connected in series, in parallel, or in series-parallel connection, and the whole composed of the multiple battery cells may be accommodated in the housing 5. Of course, the multiple battery cells may be first connected in series, in parallel, or in series-parallel connection to form a battery module 6, and the multiple battery modules 6 may be connected in series, in parallel, or in series-parallel connection to form an integral body and then be accommodated in the housing 5.

[0068] FIG. 3 is a schematic structural diagram of a battery according to some embodiments of the present application.

[0069] In some embodiments, as shown in FIG. 3, the battery 2 includes a battery cell 7 and a thermal management member 8 for performing heat exchange with the battery cell 7 to operate the battery cell 7 within an appropriate temperature range.

[0070] In some embodiments, there are a plurality of battery cells 7, and the plurality of battery cells 7 can be connected in parallel, in series, or in series-parallel by achieving electrical connection through a bus bar member.

[0071] In some embodiments, at least a part of the thermal management member 8 is located between adjacent battery cells 7, and the thermal management member 8 can perform heat exchange with the battery cells 7 on both sides simultaneously.

[0072] In some embodiments, the battery 2 includes a plurality of battery rows, and the plurality of battery rows and the plurality of thermal management members 8 are alternately arranged along a first direction X. Each battery row includes a plurality of battery cells 7, and the arrangement direction of the plurality of battery cells 7 in the battery row may be perpendicular to the first direction X. In this embodiment, each thermal management member 8 can perform heat exchange with the plurality of battery cells 7 in the battery row simultaneously.

[0073] The thermal management member of the present application will be described in detail below with reference to the drawings.

[0074] FIG. 4 is a schematic structural diagram of a thermal management member according to some embodiments of the present application. FIG. 5 is a schematic cross-sectional view of the thermal management member shown in FIG. 4. FIG. 6 is a schematic structural diagram of a support member in the thermal management member shown in FIG. 5.

[0075] As shown in FIGS. 4, 5, and 6, the heat management member 8 of the embodiment of the present application includes a housing 81 and a support member 82. An accommodation space is provided inside the housing 81, and the housing 81 includes a first wall 811 and a second wall 812 located on both sides of the accommodation space respectively. The support member 82 is installed in the accommodation space and supported between the first wall 811 and the second wall 812. The support member 82 is configured to be deformable when receiving the pressing of the first wall 811.

[0076] The housing 81 may be of an integral structure or a separate structure. Exemplarily, the housing 81 is formed by connecting a plurality of members provided separately.

[0077] The first wall 811 and the second wall 812 are heat conduction members and are used for heat exchange with the battery cell 7.

[0078] The accommodation space is used for circulating a heat exchange medium (such as water), so that when the first wall 811 contacts the battery cell 7, the temperature of the battery cell 7 is adjusted by means of heat transfer.

[0079] The embodiment of the present application does not limit whether the support member 82 and the housing 81 have a connection relationship, that is, the support member 82 only needs to be accommodated in the housing 81 and may be fixedly connected to the housing 81.

[0080] The fact that the support member 82 in the embodiment of the present application is deformable when receiving the pressing of the first wall 811 means that the support member 82 can be compressed and deformed when receiving the pressing of the first wall 811, and when the force on the first wall 811 is removed, the support member 82 can at least partially recover the deformation. Exemplarily, the support member 82 may realize the deformable function by its own shape characteristics or by its own material properties.

[0081] The support member 82 is supported between the first wall 811 and the second wall 812 and is also deformable when the support member 82 receives the pressing of the first wall 811.

[0082] The support member 82 may be in direct contact with the first wall 811 and directly support the first wall 811. Alternatively, the support member 82 may indirectly support the first wall 811 by other structures.

[0083] The support member 82 can be in direct contact with the second wall 812 and directly support the second wall 812. Alternatively, the support member 82 may indirectly support the second wall 812 by other structures.

[0084] The support member 82 may be one or a plurality.

[0085] The support member 82 can support the first wall 811 and the second wall 812 to reduce the risk of collapse of the first wall 811 or the second wall 812. The support member 82 is deformable when the first wall 811 is pressed. Thereby, when expansion occurs during the charge and discharge cycle process of the battery cell 7, the first wall 811 deforms along with the deformation of the support member 82 under the pressing action of the battery cell 7, extrudes and secures space due to the expansion of the battery cell 7, reduces the acting force between the battery cell 7 and the thermal management member 8, and reduces the reduction range of the heat exchange area between the battery cell 7 and the thermal management member 8, thereby improving the cycle performance of the battery cell 7.

[0086] In some embodiments, the first wall 811 and the second wall 812 are installed opposite to each other along the first direction X. The support member 82 includes an inclined portion 821 at least partially installed inclined with respect to the first direction X.

[0087] The first direction X is the arrangement direction between the first wall 811 and the second wall 812. Exemplarily, the first direction X is a direction perpendicular to the first wall 811. Optionally, the first wall 811 and the second wall 812 are parallel to each other, and the first direction X is perpendicular to the second wall 812.

[0088] The inclined portion 821 may be inclined as a whole with respect to the first direction X, or only a partial region may be inclined with respect to the first direction X.

[0089] When the heat management member 8 receives a pressing force along the first direction X of the battery cell 7, the inclined portion 821 can be deformed, and the size of the deformed inclined portion 821 along the first direction X is compressed, thereby reducing the acting force between the battery cell 7 and the heat management member 8, so that the heat exchange area between the battery cell 7 and the heat management member 8 meets the requirements and improves the cycle performance of the battery cell 7.

[0090] The embodiment of the present application does not limit the specific shape of the inclined portion 821, which may be a flat plate structure, a curved plate structure, or an irregular structure combining the flat plate structure and the curved plate structure shown in FIG. 5.

[0091] Optionally, the inclined portion 821 is a flat plate structure, and the angle formed between it and the first direction X is 15° to 75°.

[0092] When the angle formed between the inclined portion 821 and the first direction X is less than 15°, since the supporting force of the inclined portion 821 on the first wall 811 and the second wall 812 is relatively large, it is difficult for the heat management member 8 to be compressed. When the angle formed between the inclined portion 821 and the first direction X is greater than 75°, since the supporting force of the inclined portion 821 on the first wall 811 and the second wall 812 is relatively small, the heat management member 8 is easily damaged when receiving a relatively large concentrated stress, or because the compression deformation amount is relatively large, it contacts the second wall 812 and blocks the accommodation space. By setting the angle formed between the inclined portion 821 and the first direction X within the range of 15° to 75°, it can not only ensure that the heat management member 8 is compressed and slightly deformed, but also reduce the risk of damage when the heat management member 8 receives a relatively large concentrated stress, or avoid the occurrence of the situation where it contacts the second wall 812 and blocks the accommodation space due to a relatively large compression deformation amount.

[0093] Optionally, the inclined portion 821 has a flat plate structure, and the angle formed between it and the first direction X is 15°, 25°, 30°, 45°, 60°, 65°, or 75°.

[0094] In some embodiments, the inclined portion 821 has a flat plate structure, and the angle formed between it and the first direction X is between 30° and 60°.

[0095] In some embodiments, the inclined portion 821 has a curved plate structure. The angle α formed between the inclined portion 821 and the first direction X is the angle formed between the tangent line at the midpoint along the first direction X of the curved plate structure and the first direction X. α is between 15° and 75°. Optionally, α is 15°, 25°, 30°, 45°, 60°, 65°, or 75°.

[0096] In some embodiments, α is between 30° and 60°. Optionally, α is 45°.

[0097] In some embodiments, a plurality of inclined portions 821 are provided, and the plurality of inclined portions 821 are arranged along a second direction Y perpendicular to the first direction X.

[0098] Optionally, the second direction Y is parallel to the width direction of the housing 81.

[0099] In the embodiments of the present application, the shapes of the plurality of inclined portions 821 may be the same, may be different from each other, or only the shapes of some of the inclined portions 821 may be the same. When the inclined portion 821 has a flat plate structure, the angles formed between the plurality of inclined portions 821 and the first direction X may all be the same, may be different from each other, or only the angles formed between some of the inclined portions 821 and the first direction X may be the same.

[0100] By providing a plurality of inclined portions 821, the supporting force on the first wall 811 and the second wall 812 can be increased, and the risk of damage when the heat management member 8 receives a relatively large concentrated stress can be reduced.

[0101] In some embodiments, the plurality of inclined portions 821 are integrally formed.

[0102] In some embodiments, the directions in which two adjacent inclined portions 821 incline are opposite.

[0103] In the first direction X, each inclined portion 821 has a first end close to the first wall 811 and a second end close to the second wall 812. The fact that the directions in which two adjacent inclined portions 821 incline are opposite means that, with each first end as a reference point, the two inclined portions 821 incline in a direction approaching each other or in a direction moving away from each other.

[0104] In this embodiment, the fact that the directions in which two adjacent inclined portions 821 incline are opposite means that the directions in which at least two adjacent inclined portions 821 incline are opposite. Optionally, the directions in which any two adjacent inclined portions 821 incline are opposite.

[0105] The inventor found that when the directions in which the plurality of inclined portions 821 incline are all the same, after the heat management member 8 receives the pressing force in the first direction X, the heat management member 8 is relatively easy to deform, but the resilience after deformation is relatively weak. Therefore, a gap is likely to occur between the heat management member 8 and the battery cell 7, reducing the heat exchange area between the heat management member 8 and the battery cell 7. In view of this, the inventor reverses the inclination directions of two adjacent inclined portions 821, thereby significantly increasing the resilience after the support member 82 deforms, increasing the contact area between the housing 81 and the battery cell 7, and improving the heat management ability of the heat management member 8 with respect to the battery cell 7.

[0106] In some embodiments, in the second direction Y, a flow path 83 is formed between adjacent inclined portions 821.

[0107] The plurality of inclined portions 821 can partition the accommodation space into a plurality of flow paths 83. When the heat exchange medium enters the accommodation space, the heat exchange medium can be divided into the plurality of flow paths 83. Thereby, when the heat management member 8 contacts the battery cell 7, the temperature of each part of the battery cell 7 can be adjusted relatively uniformly.

[0108] In some embodiments, the support member 82 includes a plurality of arch structures 822 arranged along the second direction Y, and each arch structure 822 includes two adjacent inclined portions 821.

[0109] The embodiments of the present application do not limit the degree of curvature of the plurality of arch structures 822. The degrees of curvature of the plurality of arch structures 822 may be the same, may be different from each other, or only the degrees of curvature of some of the arch structures 822 may be the same. The arch structure 822 in the embodiments of the present application refers to an integral curved structure.

[0110] The opening direction of the arch structure 822 in the embodiments of the present application is not limited, and it may face the first wall 811 or the second wall 812.

[0111] The arch structure 822 has relatively good elasticity, which enhances the resilience ability after the support member 82 is deformed, further increases the contact area between the housing 81 and the battery cell 7, and improves the heat management ability of the heat management member 8 with respect to the battery cell 7.

[0112] Both of the two inclined portions 821 of the arch structure 822 are curved plate structures. Compared with the flat plate structure, the curved plate structure is easier to deform and has a higher resilience ability after deformation. Therefore, the arch structure 822 can not only reduce the acting force with the heat management member 8 during the expansion process of the battery cell 7 and improve the cycle performance of the battery cell 7, but also the relatively strong resilience ability increases the contact area between the housing 81 and the battery cell 7, and improves the heat management ability of the heat management member 8 with respect to the battery cell 7.

[0113] In some embodiments, the end portion of the arch structure 822 adjacent to the second wall 812 along the first direction X of the arch structure abuts against and is connected to the second wall 812.

[0114] The arch structure 822 may be connected to the second wall 812 by adhesion, locking, welding, or other means.

[0115] The arch structure 822 is connected to the second wall 812, which can increase the connection strength between the arch structure 822 and the housing 81, reduce the risk of the support member 82 swinging within the accommodation space, and improve the stability of the support member 82.

[0116] A plurality of arch structures 822 can partition the accommodation space into a plurality of flow channels 83. When the heat exchange medium enters the accommodation space, the heat exchange medium can be divided into multiple streams through the plurality of flow channels 83. Thereby, when the heat management member 8 contacts the battery cell 7, the temperature of each part of the battery cell 7 can be adjusted relatively uniformly.

[0117] Optionally, the opening of the arch structure 822 faces the first wall 811.

[0118] In some embodiments, the support member 82 further includes a connection portion 823. The connection portion 823 connects two adjacent inclined portions 821 and abuts against the first wall 811.

[0119] The embodiments of the present application do not limit the shape of the connection portion 823, which may be a flat plate structure, a curved plate structure, or an irregular structure formed by a combination of a flat plate structure and a curved plate structure.

[0120] Optionally, the connection portion 823 and the two adjacent inclined portions 821 are of an integral structure.

[0121] Install the connecting part 823, integrally connect the two inclined parts 821 by the connecting part 823, increase the structural strength of the support member 82, the plurality of inclined parts 821 form the whole, increase the resilience ability after deforming in the first direction X, and improve the heat management ability of the heat management member 8 for the battery cell 7. The connecting part 823 can increase the distance between the two inclined parts 821 and increase the overcurrent area of the flow path surrounded by the connecting part 823 and the two inclined parts 821.

[0122] In some embodiments, the support member 82 includes a plurality of arch structures 822 arranged along the second direction Y. Each arch structure 822 includes two adjacent inclined parts 821, and the adjacent arch structures 822 are connected by the connecting part 823.

[0123] The arch structure 822 of the embodiment of the present application includes one curved top end and two free ends facing the top end. The connecting part 823 of the embodiment of the present application is connected to the adjacent free ends of the two arch structures 822.

[0124] The embodiment of the present application does not limit the shape of the connecting part 823, which may be a flat plate structure, a curved plate structure, or an irregular structure formed by a combination of a flat plate structure and a curved plate structure.

[0125] Optionally, the arch structure 822 and the connecting part 823 are an integral structure.

[0126] The adjacent arch structures 822 are connected by the connecting part 823, the structural strength of the support member 82 can be increased, the plurality of arch structures 822 form the whole, the resilience ability after deforming in the first direction X can be increased, and the heat management ability of the heat management member 8 for the battery cell 7 can be improved. The connecting part 823 can increase the distance between the two arch structures 822 and increase the overcurrent area of the flow path surrounded by the connecting part 823 and the two arch structures 822.

[0127] In some embodiments, the connecting part 823 is welded to the first wall 811, and the arch structure 822 is welded to the second wall 812.

[0128] The opening of the arch structure 822 in the embodiment of the present application faces the first wall 811, and the curved top of the arch structure 822 is welded to the second wall 812.

[0129] The connecting portion 823, the first wall 811, the arch structure 822, and the second wall 812 are all connected by welding, which can increase the connection fastening property between the support member 82 and the housing 81, increase the supporting force of the support member 82 against the first wall 811 and the second wall 812, and reduce the risk of damage when the heat management member 8 receives a relatively large concentrated stress. Moreover, the support member 82 is connected to both the first wall 811 and the second wall 812, and the first wall 811 covers the opening of the arch structure 822. Therefore, the arch structure 822 and the first wall 811 are peripherally arranged to form a flow path 83. The second wall 812 covers one side away from the connecting portion 823 and the arch-shaped openings of the two adjacent inclined portions 821. Therefore, the connecting portion 823, the back sides of the two adjacent arch structures 822, and the second wall 812 are also peripherally arranged to form a flow path 83. Therefore, the support member 82, the first wall 811, and the second wall 812 are peripherally arranged to form a plurality of mutually independent flow paths 83. When the heat exchange medium enters the accommodation space, the heat exchange medium can be divided into the plurality of flow paths 83, so that when the heat management member 8 contacts the battery cell 7, the temperature of each part of the battery cell 7 can be adjusted relatively uniformly.

[0130] In some embodiments, a liquid inlet 813 and a liquid outlet 814 communicating with the accommodation space are provided in the housing 81. The heat exchange medium enters from the liquid inlet 813, flows through the accommodation space, and then exits from the liquid outlet 814.

[0131] In some embodiments, the housing 81 includes a first case 818 and a second case 819, and the first case 818 and the second case 819 are connected to surround the accommodation space. The first case 818 includes the first wall 811, and the second case 819 includes the second wall 812.

[0132] In the first case 818 and the second case 819 of the embodiments of this application, a heat-conducting material is used. Optionally, in the first case 818, an iron-carbon alloy is used.

[0133] In some embodiments, a first recess 8181 is provided on one side of the first case 818 facing the second case 819, and a second recess 8191 is provided on one side of the second case 819 facing the first case 818. The accommodation space includes the first recess 8181 and the second recess 8191. The bottom wall of the first recess 8181 is the first wall 811, and the bottom wall of the second recess 8191 is the second wall 812.

[0134] The embodiments of this application do not limit either the shape or the depth of the recess of the first recess 8181 and the second recess 8191. The cross-section in the longitudinal direction of the first recess 8181 and the second recess 8191 themselves may be trapezoidal, rectangular, or other shapes.

[0135] Both the first case 818 and the second case 819 are recessed outward, and the volume of the accommodation space can be made relatively large, so that more heat exchange medium can be accommodated, and the cooling effect on the battery cell 7 can be enhanced. In some embodiments, the liquid inlet 813 and the liquid outlet 814 may be installed on the first case 818 simultaneously, may be installed on the second case 819 simultaneously, or may be installed on the first case 818 and the second case 819 respectively.

[0136] FIG. 7 is a schematic diagram of a local structure of a heat management member according to some other embodiments of this application.

[0137] As shown in FIG. 7, in some embodiments, the material of the support member 82 is an elastic material.

[0138] The elastic material of the embodiments of this application needs to have the ability to generate a certain deformation and at least partially recover the deformation when the external force is removed. For example, the material of the support member 82 may be rubber or silica gel.

[0139] The embodiments of the present application do not limit the shape of the support member 82, which may be cylindrical, cuboid or spherical.

[0140] In some embodiments, the number of support members 82 is plural.

[0141] The support member 82 is made of an elastic material, and the elastic material is easy to deform and has a high repulsion ability after deformation. Therefore, when the heat management member 8 receives a pressing force along the first direction X, the support member 82 is relatively easy to deform, which can significantly reduce the acting force between the battery cell 7 and the heat management member 8, and not only can improve the cycle performance of the battery cell 7, but also the relatively good repulsion ability can further increase the contact area between the heat management member 8 and the battery cell 7, and improve the heat management ability of the heat management member 8 for the battery cell 7.

[0142] In some embodiments, the support member 82 has a porous structure.

[0143] The porous structure of the embodiments of the present application may be a sponge or a structure having other relatively many voids.

[0144] The support member 82 adopts a porous structure. Due to the relatively many voids in the porous structure, it is easy to deform. Therefore, when the heat management member 8 receives a pressing force along the first direction X, the support member 82 is relatively easy to deform, which can significantly reduce the acting force between the battery cell 7 and the heat management member 8, and improve the cycle performance of the battery cell 7.

Two adjacent connecting portions 823 are connected in a one-to-one correspondence to both ends on the opposite side of the inclination direction of the inclined portion 821.

[0156] The plurality of flow paths 83 communicate with the first bus bar region 815 and the second bus bar region 816. The heat exchange medium enters the first bus bar region 815 from the liquid inlet 813, flows through the plurality of flow paths 83, enters the second bus bar region 816, and then flows out from the liquid outlet 814. By providing the first bus bar region 815 and the second bus bar region 816, if the plurality of flow paths 83 are communicated with the first bus bar region 815 and the second bus bar region 816, they can be communicated with the liquid inlet 813 and the liquid outlet 814. Therefore, by providing one liquid inlet 813 and one liquid outlet 814, the plurality of independent flow paths 83 can be communicated, and thereby the heat exchange medium can flow through all of the plurality of flow paths 83 in the support member 82.

[0157] In some embodiments, the first bus bar region 815 and the second bus bar region 816 are located on both sides along the third direction Z of the support member 82.

[0158] The third direction Z of the embodiments of the present application intersects the first direction X.

Further, the heat exchange medium flows from the first bus bar region 815 along the third direction Z through the plurality of flow paths 83 and reaches the second bus bar region 816.

The running path of the heat exchange medium is relatively flat, and the heat exchange effect is relatively high.

[0161] FIG. 13 is a schematic diagram of the internal flow path of the heat management member according to some other embodiments of the present application.

[0162] As shown in FIG. 13, in some embodiments, the support member 82 includes a main body portion 824 and a partition portion 825 protruding from one end along the third direction Z of the main body portion 824.

Optionally, the area of the third bus bar region 817 is larger than the area of either the first bus bar region 815 or the second bus bar region 816.

[0165] Optionally, the plurality of flow paths 83 are independent of each other. That is, the heat exchange medium in each flow path 83 does not flow into other flow paths 83.

[0166] The heat exchange medium enters the first flow path 831 from the first bus bar region 815, then flows into the third bus bar region 817 along the third direction Z, enters the second flow path 832 from the third bus bar region 817, and then flows into the second bus bar region 816 along the third direction Z again, and flows out from the liquid outlet 814.

[0167] The liquid inlet 813 and the liquid outlet 814 of the embodiment of the present application are located on the same side facing the partition portion 825 of the main body portion 824.
