[0058] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0059] Reference below Figure 1-Figure 12 A battery device 101 according to an embodiment of the present invention is described.

[0060] Reference Figure 8 According to the first embodiment of the utility model, the battery device 101 includes: a device housing 10, at least one battery module 21 and a first spoiler structure 31. The first spoiler structure 31 is arranged in the device housing 10 and is arranged on at least one side of the battery module 21. The first spoiler structure 31 can spoil the heat exchange medium. For example, the device housing 10 is formed with a liquid inlet 11 and a liquid outlet 12 for the heat exchange medium to enter and exit. The liquid heat exchange medium of the battery device 101 can enter the device housing 10 from the liquid inlet 11. After the heat exchange medium entering the device housing 10 exchanges heat with the battery module 21, it can flow out from the liquid outlet 12, thereby realizing the temperature regulation of the battery module 21.

[0061] Optionally, the battery device 101 may further include a fixing frame 15 , which is disposed on the device housing 10 to fix the battery module 21 .

[0062] Among them, the temperature regulation of the battery module 21 by the heat exchange medium may include cooling the battery module 21 to avoid the battery device 101 from being too hot when it is working. Optionally, the heat exchange medium is a coolant. During the operation of the battery device 101, the temperature of the battery module 21 rises. Excessive temperature may cause the diaphragm to melt through and short-circuit, and ultimately lead to dangers such as explosion and fire. By arranging a coolant in the battery device 101, the battery module 21 can exchange heat with the coolant during operation. After the heat is transferred to the coolant, the coolant leaves the battery device 101 through the liquid outlet 12. During operation, the battery module 21 exchanges heat with the coolant to continuously dissipate heat, thereby ensuring that the operating temperature of the battery device 101 is not too high and avoiding danger to the battery.

[0063] The temperature regulation of the battery module 21 by the heat exchange medium may include heating the battery module 21 so that when the external ambient temperature is too low, the temperature of the battery module 21 is within a temperature range where it can be started and operated. Optionally, the heat exchange medium is an antifreeze liquid. When the battery is in an extremely cold environment, it may not be able to operate normally due to the low temperature, and preheating is required before starting. By providing antifreeze liquid in the battery device 101, the battery module 21 exchanges heat with the antifreeze liquid, and the temperature of the battery module 21 is increased, the battery device 101 can be started quickly and operate normally in a low temperature environment.

[0064] Furthermore, a first spoiler structure 31 is provided in the device shell 10. When the heat exchange medium flows in the device shell 10, the heat exchange medium is in direct contact with the first spoiler structure 31. The first spoiler structure 31 can disturb the heat exchange medium in the device shell 10, so that the heat exchange medium flowing through the device shell 10 is turbulent. Compared with the laminar flow of the heat exchange medium, the heat exchange efficiency of the heat exchange medium forming turbulent flow and the battery module 21 is higher, the heat exchange rate is faster, and the heat exchange effect between the heat exchange medium and the battery module 21 is better.

[0065] According to the battery device 101 of the embodiment of the utility model, by providing a first spoiler structure 31 for spoiling the heat exchange medium on at least one side of the battery module 21 inside the battery device 101, the heat exchange medium can form turbulent flow. Compared with laminar flow, the formed turbulent flow can enhance the heat exchange effect between the heat exchange medium and the battery module 21, improve the heat exchange efficiency, and thus enhance the temperature regulation effect of the battery module 21.

[0066] According to some embodiments of the present invention, reference Fig.10The first spoiler structure 31 includes a spoiler plate 32 and a spoiler protrusion 33 provided on the spoiler plate 32, and the spoiler protrusion 33 is located on at least one side of the spoiler plate 32 along the first direction. The spoiler protrusion 33 being located on at least one side of the spoiler plate 32 along the first direction includes the following situations: for example, the spoiler protrusion 33 is located on one side of the spoiler plate 32 along the first direction, or the spoiler protrusion 33 is provided on both opposite sides of the spoiler plate 32 along the first direction. By making the spoiler protrusion 33 located on at least one side of the spoiler plate 32 along the first direction, the spoiler of the first spoiler structure 31 can be made more sufficient, so that the heat exchange medium forms turbulence and the heat exchange rate is faster.

[0067] The spoiler convex blocks 33 located on the same side of the spoiler 32 along the first direction may be multiple and spaced apart. For example, there may be ten spoiler convex blocks 33 located on the same side of the spoiler 32 along the first direction. By arranging multiple spoiler convex blocks 33 on the same side of the spoiler 32 along the first direction, the first spoiler structure 31 can more fully spoil the heat exchange medium, thereby increasing the heat exchange rate of the heat exchange medium.

[0068] By configuring the first spoiler structure 31 to include a spoiler plate 32 and a spoiler protrusion 33 disposed on the spoiler plate 32, the first spoiler structure 31 is simple and convenient to manufacture, and it is also convenient to install the first spoiler structure 31. When the heat exchange medium flows through the first flow space 22, the spoiler protrusion 33 can achieve a spoiling effect on the heat exchange medium, so that the heat exchange medium flowing through the first flow space 22 forms a turbulent flow.

[0069] According to some embodiments of the present invention, reference Figure 3 and Figure 4 , the liquid inlet 11 and the liquid outlet 12 are located on opposite sides of the device housing 10 along the second direction, and the spoiler protrusion 33 extends along the second direction. By arranging the liquid inlet 11 and the liquid outlet 12 on opposite sides of the device housing 10 along the second direction, the heat exchange medium can flow naturally along the second direction in the device housing 10 after entering the battery module 100 from the liquid inlet 11, and leave the battery module 100 from the liquid outlet 12 after fully exchanging heat with the battery module 21. At the same time, by extending the spoiler protrusion 33 along the second direction, the spoiler protrusion 33 can guide the heat exchange medium, so that the heat exchange medium can flow through all surfaces, avoiding the formation of dead zones due to insufficient turbulence at local locations. For example, when the heat exchange medium is a coolant, the spoiler protrusion 33 extends along the second direction to guide the coolant, and the coolant cools all surfaces to avoid local hot spots.

[0070] The spoiler protrusions 33 are arranged to extend along the second direction, so that when the heat exchange medium flows in the device housing 10 along the second direction, it passes through the spoiler protrusions 33 in sequence, so as to achieve a uniform spoiler distribution.

[0071] According to some embodiments of the utility model, the spoiler protrusions 33 located on the same side of the spoiler 32 along the first direction are multiple and arranged at intervals along the third direction (for example, refer to the e3 direction in the accompanying drawings), and the first flow channel 34 extending along the second direction is defined between the spoiler protrusions 33 adjacent to each other in the third direction, and the third direction, the second direction and the first direction are perpendicular to each other. By setting the spoiler protrusions 33 located on the same side of the spoiler 32 along the first direction to multiple and arranged at intervals along the third direction, the heat exchange medium can be turbulent multiple times when flowing in the first flow space 22 along the second direction, so that the turbulence is more sufficient and the heat exchange efficiency is better.

[0072] According to some embodiments of the present invention, reference Fig.10 The projection of the first flow channel 34 on the first reference plane is the first projection, the first projection extends non-linearly in the second direction, and the first reference plane is perpendicular to the first direction. By making the projection of the first flow channel 34 on the first reference plane extend non-linearly in the second direction, the heat exchange medium can make multiple turns when flowing through the first flow channel 34, change the flow direction and speed, achieve a sufficient turbulent effect, and improve the heat exchange efficiency of the heat exchange medium.

[0073] According to some embodiments of the utility model, the spoiler convex block 33 includes a long strip portion 35 and a plurality of protrusions 36, the long strip portion 35 extends along the second direction, and the plurality of protrusions 36 are connected to at least one side of the long strip portion 35 along the third direction. By connecting the plurality of protrusions 36 to at least one side of the long strip portion 35 along the third direction, the heat exchange medium can collide with the protrusions 36 multiple times when flowing along the long strip portion 35, changing the flow direction and speed, achieving a sufficient turbulent flow effect, and improving the heat exchange efficiency of the heat exchange medium.

[0074] The plurality of protrusions 36 on the same side of the long strip 35 are arranged at intervals along the second direction, and the third direction, the second direction and the first direction are perpendicular to each other. By arranging the plurality of protrusions 36 on the same side of the long strip 35 to be arranged at intervals along the second direction, the heat exchange medium can be made to bend continuously when flowing along the long strip 35, and the flow direction can be changed multiple times, so as to achieve a sufficient turbulent flow effect and improve the heat exchange efficiency of the heat exchange medium.

[0075] According to some embodiments of the present invention, reference Fig.10 A second flow channel 37 extending along the second direction is formed in the spoiler protrusion 33. By providing the second flow channel 37 in the spoiler protrusion 33, the space in the spoiler protrusion 33 can be fully utilized to provide more space for the flow of the heat exchange medium in the device housing 10, so that more heat exchange medium flows through the device housing 10, thereby improving the heat exchange effect.

[0076] For example, the spoiler protrusion 33 is located on one side of the spoiler plate 32 along the first direction, or the spoiler protrusions 33 are provided on two opposite sides of the spoiler plate 32 along the first direction.

[0077] According to some embodiments of the present invention, reference Fig.10 At least one side of the spoiler protrusion 33 along the third direction is formed with a turbulence hole 38 connected to the second flow channel 37. The third direction, the second direction and the first direction are perpendicular to each other. For example, the turbulence hole 38 is located on one side of the spoiler protrusion 33 along the third direction, or the spoiler protrusion 33 is provided with turbulence holes 38 on both sides along the third direction. The turbulence hole 38 has the function of turbulence, changes the flow direction of the fluid, and makes the heat exchange effect of the heat exchange medium better. For example, the turbulence hole 38 can be set on one side of the spoiler protrusion 33 along the third direction, or on both sides along the third direction.

[0078] According to some embodiments of the utility model, the turbulence holes 38 located on the same side of the spoiler protrusion 33 along the third direction are multiple and are arranged at intervals along the second direction. For example, the turbulence holes 38 located on the same side of the spoiler protrusion 33 along the third direction can be ten and are arranged at intervals along the second direction. By setting the turbulence holes 38 to be multiple and arranged at intervals along the second direction, during the process of the heat exchange medium flowing along the first flow channel 34 and the second flow channel 37, the turbulence effect can be further enhanced by the action of the turbulence holes 38, which can increase the effect of turbulence, make the turbulence more sufficient, and improve the heat exchange effect.

[0079] According to some embodiments of the utility model, the spoiler protrusions 33 located on the same side of the spoiler plate 32 along the first direction are multiple and arranged at intervals along the third direction, and the first flow channel 34 extending along the second direction is defined between the spoiler protrusions 33 adjacent to each other in the third direction, and the third direction, the second direction and the first direction are perpendicular to each other, and the turbulence holes 38 connect the second flow channel 37 with the first flow channel 34. By connecting the turbulence holes 38 with the second flow channel 37 and the first flow channel 34, the first spoiler structure 31 can be completely connected along the third direction, the heat exchange medium has more flow direction options, the turbulence is more sufficient, and the heat exchange efficiency is higher.

[0080] According to some embodiments of the present invention, reference Fig. 9, the projection of the spoiler 32 on the second reference plane is the second projection, the second projection extends in a zigzag shape, and the second reference plane is parallel to the first direction. By setting the projection of the spoiler 32 on the second reference plane to be a zigzag shape, the contact area between the spoiler 32 and the heat exchange medium can be increased when the size of the device housing 10 in the third direction is constant, and the heat exchange efficiency and heat exchange effect can be improved. In addition, by extending the spoiler 32 in a zigzag shape, the spoiler 32 itself can also have a spoiler effect under the spoiler protrusion 33 having a spoiler effect, increasing the spoiler area, further improving the spoiler effect and spoiler effect of the first spoiler structure 31, making the turbulence more sufficient and the heat exchange effect better.

[0081] According to some embodiments of the present invention, reference Figure 4 and Figure 8 , the liquid inlet 11 and the liquid outlet 12 are located on opposite sides of the device housing 10 along the second direction, and the spoiler 32 extends in a zigzag shape in the third direction, and the third direction, the second direction and the first direction are perpendicular to each other. By extending the spoiler 32 in a zigzag shape in the third direction, the spoiler 32 can guide the heat exchange medium, and the heat exchange medium entering the first flow space 22 from the liquid inlet 11 can naturally flow along the second direction along the spoiler 32, and then flow to the liquid outlet 12. The spoiler 32 guides the heat exchange medium to flow completely through the first flow space 22 along the second direction, avoiding dead corners in the flow, resulting in poor local heat exchange effect of the battery module 21, and the difference between the local temperature and the overall temperature, which may cause danger.

[0082] According to some embodiments of the present utility model, the battery device 101 includes at least two battery modules 21, at least two battery modules 21 are arranged along the first direction, and a first spoiler structure 31 is provided between two adjacent battery modules 21. By providing the first spoiler structure 31 between two adjacent battery modules 21, a turbulent flow can be formed when the heat exchange medium flows through the two adjacent battery modules 21, thereby enhancing the heat exchange effect between the heat exchange medium and the battery module and improving the heat exchange efficiency.

[0083] According to some embodiments of the present invention, reference Figure 4 and Figure 8 There is a first flow space for the flow of heat exchange medium between two adjacent battery modules, a first spoiler structure is provided in the first flow space, and the first flow space 22 connects the liquid inlet 11 and the liquid outlet 12. The first flow space 22 can be defined between two adjacent battery modules 21, or the first flow space 22 can be defined in a temperature regulating component placed between two adjacent battery modules 21. The heat exchange medium that enters the device housing 10 from the liquid inlet 11 can flow through the first flow space 22. In the process of the heat exchange medium flowing through the first flow space 22, the heat exchange medium can exchange heat with the two adjacent battery modules 21, thereby regulating the temperature of the battery modules 21.

[0084] For example, refer to Figure 4 and Figure 8 The battery module 100 includes two battery modules 21, and a first flow space 22 is arranged between the two battery modules 21. The heat exchange medium enters the battery module 100 from the liquid inlet 11, flows through the first flow space 22, exchanges heat with the battery module 21, and then leaves the battery module 100 from the liquid outlet 12.

[0085] According to some embodiments of the utility model, the first spoiler structure 31 is a flexible structure. By making the first spoiler structure 31 a flexible structure, when the first spoiler structure 31 is installed between two adjacent battery modules 21, the deformation of the flexible structure can be used to make the first spoiler structure 31 interference fit between the two adjacent battery modules 21, and the first spoiler structure 31 is installed by being clamped by two adjacent battery modules 21, so that the first spoiler structure 31 is easy to install and does not need to add additional assembly parts.

[0086] According to some embodiments of the present invention, reference Figure 4 and Figure 8 The first spoiler structure 31 is interference fit with the first flow space 22. By making the first spoiler structure 31 and the first flow space 22 interference fit, the position of the first spoiler structure 31 can be fixed, which facilitates the installation and fixation of the first spoiler structure 31 without adding additional assembly limiting components.

[0087] According to some embodiments of the present invention, reference Figure 6 and Figure 7 The device housing 10 has a first shell plate 13 and a second shell plate 14 arranged opposite to each other along a first direction; wherein a first spoiler structure 31 is provided between the battery module 21 and the first shell plate 13; and / or, a first spoiler structure 31 is provided between the battery module 21 and the second shell plate 14.

[0088] For example, when the battery device 101 includes a battery module 21 , a first spoiler structure 31 is provided between the battery module 21 and the first shell plate 13 ; and / or a first spoiler structure 31 is provided between the battery module 21 and the second shell plate 14 .

[0089] For example, when the battery device 101 includes multiple battery modules 21, a first spoiler structure 31 is provided between the battery module 21 closest to the first shell plate 13 and the first shell plate 13; and / or a first spoiler structure 31 is provided between the battery module closest to the second shell plate 14 and the second shell plate 14.

[0090] According to some embodiments of the present invention, reference Figure 6 and Figure 7A second flow space 23 for the flow of heat exchange medium is defined between the battery module 21 and the first shell plate 13, a first spoiler structure 31 is provided in the second flow space 23, and the second flow space 23 connects the liquid inlet 11 and the liquid outlet 12; and / or, a third flow space 24 for the flow of heat exchange medium is defined between the battery module 21 and the second shell plate 13, the third flow space 24 connects the liquid inlet 11 and the liquid outlet 12, and a first spoiler structure 31 is provided in the third flow space 24.

[0091] For example, when the battery device 101 includes a plurality of battery modules 21, a second flow space 23 for the flow of a heat exchange medium is defined between the battery module 21 closest to the first shell plate 13 and the first shell plate 13, and the second flow space 23 is provided with a first spoiler structure 31. A third flow space 24 for the flow of a heat exchange medium is defined between the battery module 21 closest to the second shell plate 14 and the second shell plate 14, and the third flow space 24 is provided with a first spoiler structure 31.

[0092] For example, a first spoiler structure 31 may be provided in the first flow space 22 and the second flow space 23 in the battery module 100, so that the heat exchange medium is spoiled in the first flow space 22 and the second flow space 23, and sufficient heat exchange is performed on the battery module 21. A first spoiler structure 31 may also be provided in the first flow space 22 and the third flow space 24 in the battery module 100, so that the heat exchange medium is spoiled in the first flow space 22 and the third flow space 24, and sufficient heat exchange is performed on the battery module 21. Alternatively, a first spoiler structure 31 may be provided in the first flow space 22, the second flow space 23, and the third flow space 24 in the battery module 100, so that the heat exchange medium is spoiled in the first flow space 22, the second flow space 23, and the third flow space 24, and sufficient heat exchange is performed on the battery module 21.

[0093] By providing the second flow space 23 and the third flow space 24, it is ensured that the battery module 21 can also obtain sufficient heat exchange on the side close to the first shell plate 13 or the second shell plate 14, avoiding danger caused by insufficient local heat exchange. By providing the first spoiler structure 31 in the second flow space 23 and the third flow space 24, the heat exchange medium can also obtain sufficient turbulence in this part, avoiding different temperatures caused by different heat exchange efficiencies at different positions of the battery module 21, damaging components or causing danger.

[0094] According to some embodiments of the present invention, reference Figure 8 and Fig.11The battery device 101 further includes: a second spoiler structure 40, which is disposed in the device housing 10 and between the liquid inlet 11 and the battery module 21. By arranging the second spoiler structure 40 between the liquid inlet 11 and the battery module 21, the heat exchange medium can be disturbed by the second spoiler structure 40 before entering the first flow space 22, the second flow space 23, or the third flow space 24, forming turbulence, so that the heat exchange is more sufficient. At the same time, the second spoiler structure 40 is combined with the first spoiler to form a secondary spoiler, so that the heat exchange medium is more fully turbulent, and the heat exchange efficiency of the heat exchange medium is improved.

[0095] According to some embodiments of the present invention, reference Figure 5 and Figure 8 The second spoiler structure 40 includes a spoiler cover 41, and a spoiler cavity 42 communicating with the liquid inlet 11 is defined between the spoiler cover 41 and the device housing 10. By defining a spoiler communicating with the liquid inlet 11 between the spoiler cover 41 and the device housing 10, the heat exchange medium can be turbulent when entering the battery device 101, so that the heat exchange is more sufficient.

[0096] For example, in some embodiments of the present invention, refer to Figure 4 and Figure 8 Two liquid inlets 11 are formed on the same side of the device housing 10, and the two liquid inlets 11 can be arranged at intervals along the third direction. The second spoiler structure 40 includes two spoiler covers 41, and the two spoiler covers 41 correspond to the two liquid inlets 11 respectively. The two spoiler covers 41 can be arranged along the third direction, and a spoiler cavity 42 connected to the corresponding liquid inlet 11 is defined between each spoiler cover 41 and the device housing 10. By setting the two liquid inlets 11, the liquid inlet speed and liquid inlet amount are increased, and the heat exchange efficiency is improved.

[0097] According to some embodiments of the utility model, the spoiler 41 is detachably connected to the device housing 10. By arranging the spoiler 41 and the device housing 10 to be detachably connected, the installation between the spoiler 41 and the device housing 10 can be made more convenient, easy to assemble, and the user can also disassemble and clean the spoiler 41 more conveniently.

[0098] According to some embodiments of the present invention, reference Fig.12 The second spoiler structure 40 further includes a spoiler filter 44, which is disposed in the spoiler cavity 42 and has a plurality of spoiler filter holes 45. The spoiler filter 44 has a plurality of spoiler filter holes 45, which not only spoils the heat exchange medium, but also filters the heat exchange medium, thereby preventing solid impurities in the heat exchange medium from entering the battery module 100 and affecting the operation and life of the battery module 100.

[0099] According to some embodiments of the present invention, reference Fig.12 The spoiler filter 44 is a porous structure. By setting the spoiler filter 44 as a porous structure, the spoiler filter 44 can have a certain adsorption capacity, can better play a filtering role, and can have a better spoiler effect.

[0100] According to some embodiments of the present invention, reference Fig.11 The spoiler cover 41 includes a cover body 46 and a limiting rib plate 47. The cover body 46 is open on one side facing the device housing 10 to form an open opening 48. A spoiler cavity 42 is defined between the cover body 46 and the device housing 10. The limiting rib plate 47 is disposed at the open opening 48 and defines an accommodation space 49 for accommodating the spoiler filter 44 between the cover body 46. The limiting rib plate 47 is used to limit the spoiler filter 44, so as to facilitate the installation and fixation of the spoiler filter 44.

[0101] According to some embodiments of the present invention, reference Fig.11 An insertion port 50 is formed on one side of the cover body 46 along the first direction, and the spoiler filter 44 is suitable for being inserted into the accommodating space 49 through the insertion port 50. By providing the insertion port 50 on one side of the cover body 46 along the first direction, it is easier to install and remove the spoiler filter 44, and it is more convenient for the user to replace the spoiler filter 44.

[0102] According to some embodiments of the utility model, the battery device 101 includes at least two battery modules 21, at least two battery modules 21 are arranged along the first direction, and a first flow space 22 for the flow of heat exchange medium is provided between two adjacent battery modules 21, a first spoiler structure 31 is provided in the first flow space 22, the first flow space 22 is connected to the liquid inlet 11 and the liquid outlet 12, a through hole 43 is formed on the spoiler cover 41, and the first flow space 22 is connected to the spoiler cavity 42 through the through hole 43. When the heat exchange medium flows into the battery device 101 from the liquid inlet 11, the heat exchange medium passes through the spoiler cavity 42, and then enters the first flow space 22 through the through hole 43 to exchange heat with the battery module 21. By providing a through hole 43 connection between the first flow space 22 and the spoiler cavity 42, the heat exchange medium can smoothly enter the first flow space 22 from the spoiler cavity 42 to exchange heat.

[0103] According to some embodiments of the present invention, reference Figure 5 The through hole 43 on the spoiler 41 is arranged opposite to the first flow space 22. Since the first flow space 22 is located between two adjacent battery modules 21, the first flow space 22 has a greater demand for heat exchange. By arranging the through hole 43 opposite to the first flow space 22, more heat exchange medium can flow into the first flow space 22, thereby enhancing the heat exchange efficiency of the battery module 21.

[0104] According to some embodiments of the utility model, the through hole 43 on the spoiler 41 is staggered with the liquid inlet 11. By staggering the through hole 43 with the liquid inlet 11, the heat exchange medium entering the spoiler 41 from the liquid inlet 11 can enter the first flow space 22 through the through hole 43 after sufficient turbulence, so that the flow path of the heat exchange medium in the process of flowing from the liquid inlet 11 to the through hole 43 is not a straight line, thereby increasing the turbulence effect.

[0105] According to some embodiments of the utility model, at least one battery module 21 is immersed in a heat exchange medium. By immersing multiple battery modules 21 in a heat exchange medium, the battery module 21 can be in direct contact with the heat exchange medium, and the heat exchange is more direct and the heat exchange efficiency is higher. At the same time, the contact area between the battery module 21 and the heat exchange medium can be increased, so that all parts of the battery module 21 can be in contact with the heat exchange medium, increasing the efficiency of the heat exchange of the heat exchange medium, and avoiding different temperatures caused by different heat exchange efficiencies at different positions of the battery module 21 or between different battery modules 21, which may damage components or cause danger.

By stacking multiple battery modules 100 and arranging them along the first direction, the assembly of the multiple battery modules 100 is facilitated and the overall structure is relatively compact.

[0108] According to some embodiments of the present invention, reference Figure 1 The liquid inlets 11 of the multiple battery modules 100 are located on the same side, and the liquid outlets 12 of the multiple battery modules 100 are located on the same side. By locating the liquid inlets 11 of the multiple battery modules 100 on the same side, the installation of the liquid inlet pipeline is facilitated. Similarly, by locating the liquid outlets 12 of the multiple battery modules 100 on the same side, the installation of the liquid outlet pipeline can also be facilitated.

[0109] According to some embodiments of the present invention, reference Figure 1The liquid inlet 11 of each battery module 100 is connected to a liquid inlet branch pipe 71, and the liquid outlet 12 of each battery module 100 is connected to a liquid outlet branch pipe 72. The battery device 101 also includes a liquid inlet main pipe 73 and a liquid outlet main pipe 74. Each liquid inlet branch pipe 71 is connected to the liquid inlet main pipe 73, and each liquid outlet branch pipe 72 is connected to the liquid outlet main pipe 74. By connecting each liquid inlet branch pipe 71 to the liquid inlet main pipe 73, and each liquid outlet branch pipe 72 to the liquid outlet main pipe 74, the heat exchange medium of each battery module 100 can be uniformly inlet and uniformly recovered, which is convenient for management and recovery of heat exchange medium.

[0110] According to some embodiments of the present invention, reference Figure 1 The liquid inlet manifold 73 has a liquid inlet connector 75 for connecting to an external device, and the liquid outlet manifold 74 has a liquid outlet connector 76 for connecting to an external device, and the liquid outlet connector 76 and the liquid inlet connector 75 are located on the same side of the battery device 101.
