[0050] The technical solutions of the present application will be described in detail below through specific embodiments.

[0052] As Figures 1 to 7 shown, the embodiment of the present application provides a battery assembly 10, which comprises a shell 100, an electric cell assembly 200 and an electrical assembly 400. The shell 100 has a receiving cavity 101, and the electric cell assembly 200 is arranged in the receiving cavity 101. The electric cell assembly 200 is used for storing electric energy. The electrical assembly 400 is used for managing the working state of the electric cell assembly 200, and the electric cell assembly 200 inputs and outputs electric energy through the electrical assembly 400.

[0053] The electrical assembly 400 comprises a battery management module 410 and a high-voltage plug-in 420. The battery management module 410 is arranged in the receiving cavity 101, and the high-voltage plug-in 420 is located outside the shell 100 and is electrically connected with the battery management module 410.

[0054] In some embodiments, the outer side wall of the shell 100 is provided with a sunken groove 105, and the sunken groove 105 is provided with a sunken hole 103. The sunken hole 103 is provided with a first connecting piece 140 connected with the shell 100. The high-voltage plug-in 420 is arranged in the sunken groove 105 and is connected with the first connecting piece 140.

[0055] It can be understood that the battery management module 410 is electrically connected with the electric cell assembly 200. When the battery assembly 10 is applied to a vehicle, the high-voltage plug-in 420 is electrically connected with an electric drive system on the vehicle. The battery assembly 10 can provide electric energy to the electric drive system, so that the electric drive system can drive the vehicle to run.

[0056] During the assembly of the battery assembly 10, the first connecting piece 140 can be installed into the sunken hole 103. When the high-voltage plug-in 420 is installed, the high-voltage plug-in 420 can be fixedly connected with the first connecting piece 140. Since the first connecting piece 140 is arranged in the sunken hole 103, the position of the sunken hole 103 is lower than the outer side wall of the shell 100. Therefore, the outer contour of the high-voltage plug-in 420 does not interfere with the first connecting piece 140, and the high-voltage plug-in 420 can be very stably and reliably abutted against the outer side wall of the shell 100.

[0057] In the embodiments of the present application, the cables on the electrical assembly 400 can include high-voltage cables and low-voltage cables, wherein the high-voltage cables are used for inputting and outputting electric energy of the battery cell assembly 200, and the low-voltage cables are used for transmitting detection signals on the battery cell assembly 200 and control signals of the battery assembly 10. For example, the high-voltage cables used for outputting electric energy are connected with the high-voltage plug-in 420, and the electric energy outputted by the high-voltage plug-in 420 has a voltage between 200V and 1000V, including but not limited to 200V, 220V, 380V, 500V, 800V, 1000V, etc. For example, the signals transmitted by the low-voltage cables can include but are not limited to temperature signals, voltage signals, control signals of battery charging and discharging of the battery cell assembly 200, etc., and the voltage values of the low-voltage cables can include but are not limited to 12V, 24V, 36V, 64V, etc. The embodiments of the present application are not limited in this regard.

[0058] It should be noted that in the battery assembly 10 provided by the present application, the first connecting piece 140 is arranged on the outside of the shell 100 through the sink hole 103, when the high-voltage plug-in 420 is assembled outside the shell 100, the high-voltage plug-in 420 is connected with the first connecting piece 140, and at the same time, the high-voltage plug-in 420 can directly abut on the outer side wall of the shell 100, without the need to design a avoiding structure on the high-voltage plug-in 420, which simplifies the assembly structure of the high-voltage plug-in 420 and reduces the product cost.

[0059] The connection mode of the first connecting piece 140 on the shell 100 will be described in detail below.

[0060] In a possible implementation, the end face of the first connecting piece 140 towards the outside of the shell 100 can be located inside the sink hole 103, that is, the first connecting piece 140 will not protrude outside the sink hole 103, so as to avoid interference between the high-voltage plug-in 420 and the first connecting piece 140.

[0061] For example, the end face of the first connecting piece 140 towards the outside of the shell 100 is flush with the outer side wall of the shell 100.

[0062] For example, the end face of the first connecting piece 140 towards the outside of the shell 100 is lower than the outer side wall of the shell 100.

[0063] In some embodiments, the first connecting piece 140 is connected with the shell 100 by rivet connection, so as to improve the installation convenience and reliability of the first connecting piece 140.

[0064] It can be understood that the side wall of the shell 100 can be a metal sheet structure, and the first connecting piece 140 can be a rivet nut. The bottom of the sink hole 103 is provided with a hole communicating between the inside and outside of the shell 100, and the first connecting piece 140 is fixed on the hole by rivet connection, so as to improve the installation strength of the first connecting piece 140.

[0065] In some embodiments, the side wall of the shell 100 has a through hole 104, and the high-voltage plug-in 420 is opposite to the through hole 104. The high-voltage plug-in 420 is at least partially arranged in the through hole 104 and is electrically connected to the battery management module 410, so that the convenience of connecting the battery management module 410 and the high-voltage plug-in 420 can be improved when assembled.

[0066] It can be understood that the high-voltage plug-in 420 can abut against the outer side wall of the shell 100 around the through hole 104. When the high-voltage plug-in 420 is locked and fixed by the first connecting piece 140, the high-voltage plug-in 420 can be in close contact with the outer side wall of the shell 100, thereby improving the sealing performance of the high-voltage plug-in 420 and the shell 100 when cooperating.

[0067] In some embodiments, the shell 100 can have a plurality of sink holes 103, and the plurality of sink holes 103 are distributed at intervals on the circumferential side of the through hole 104, so that the installation reliability and structural strength of the high-voltage plug-in 420 on the outer wall of the shell 100 can be improved.

[0068] For example, the shell 100 can have two, three, four or more sink holes 103, and each sink hole 103 is provided with a first connecting piece 140. The specific number of the sink holes 103 and the first connecting pieces 140 is not limited in the embodiments of the present application.

[0069] In some embodiments, the outer side wall of the shell 100 is provided with a sink groove 105, and the sink hole 103 and the through hole 104 are located in the sink groove 105. The high-voltage plug-in 420 is at least partially located in the sink groove 105 and abuts against the groove bottom of the sink groove 105. In this way, the sealing performance between the high-voltage plug-in 420 and the shell 100 can be improved.

[0070] It can be understood that the sink hole 103 and the through hole 104 can be located at the groove bottom of the sink groove 105, and the groove bottom of the sink groove 105 can be a plane to ensure the installation stability of the high-voltage plug-in 420.

[0071] For example, the contour shape of the sink groove 105 matches the contour shape of the high-voltage plug-in 420, so that the assembly of the high-voltage plug-in 420 can be pre-positioned.

[0072] The specific structure of the high-voltage plug-in 420 will be described in detail below.

[0073] In a possible implementation, the high-voltage plug-in 420 can include a plug-in body 421 and a second connecting piece 422.

[0075] Exemplarily, the connecting hole 141 can be a clamping hole, the second connecting member 422 can be a clamping component, the second connecting member 422 passes through the mounting hole 4211 and is clamped in the connecting hole 141, and is in interference fit with the inner wall of the connecting hole 141, so as to improve the connection reliability.

The specific connection mode of the second connecting member 422 and the first connecting member 140 is not limited in the embodiment of the application.

[0077] Exemplarily, the mounting hole 4211 on the plug-in component body 421 is a plurality of mounting holes, the second connecting member 422 is a plurality of second connecting members, and the plurality of second connecting members 422 are respectively arranged in the plurality of mounting holes 4211 and connected with the plurality of first connecting members 140 on the shell.

[0079] It can be understood that the battery management module 410 and the high-voltage plug-in component 420 can be connected through a copper bar, the copper bar includes a positive copper bar and a negative copper bar, and the high-voltage plug-in component 420 can be provided with a positive plug-in interface and a negative plug-in interface at the end facing the outside of the shell 100.

[0080] In some embodiments, the shell 100 can include a frame, an upper cover 120 and a bottom guard plate 130, the upper cover 120 and the bottom guard plate 130 are respectively connected to the upper and lower sides of the frame and jointly surround to form the accommodation cavity 101. The high-voltage plug-in component 420 can be connected to the side wall of the frame.

[0081] It can be understood that the upper cover 120 and the upper surface of the frame are connected by fasteners such as bolts, and the contour shape of the upper cover 120 can match the contour shape of the frame. The bottom guard plate 130 and the lower surface of the frame are connected by fasteners such as bolts, and the contour shape of the bottom guard plate 130 can match the contour shape of the frame.

[0083] It should be noted that the materials of the frame, the upper cover 120 and the bottom guard plate 130 can be metal or alloy materials such as iron and aluminum, and the embodiments of the present application do not make specific limitations.

[0084] In a possible implementation, the frame can include a frame 110 and a partition beam 113, and the two ends of the partition beam 113 are respectively connected to the opposite sides of the frame 110. The partition beam 113 is configured to divide the accommodation cavity 101 into a first chamber 101a and a second chamber 101b arranged along the length direction of the shell 100. The battery cell assembly 200 is located in the first chamber 101a. The battery management module 410 is arranged in the second chamber 101b.

[0085] The length direction of the shell 100 is defined as the X direction, and the width direction of the shell 100 is defined as the Y direction. The partition beam 113 extends along the Y direction and divides the accommodation cavity 101 into the first chamber 101a and the second chamber 101b arranged along the X direction. The high-voltage plug-in component 420 is located on the outer side wall of the first chamber 101a at one end of the shell 100 along the X direction.

[0086] It can be understood that the two ends of the partition beam 113 can be connected to the inner edges of the two sides of the frame by fasteners such as bolts, or the two ends of the partition beam 113 can be respectively welded to the inner edges of the two sides of the frame, and the embodiments of the present application do not limit the specific connection mode of the partition beam 113 and the frame.

[0087] For example, the first chamber 101a can include a plurality of accommodation areas 102, and one or more battery cell modules 210 can be arranged in each accommodation area 102.

[0088] For example, the first chamber 101a can be provided with a cross beam 111 and a longitudinal beam 112, and the cross beam 111 and the longitudinal beam 112 are perpendicular to each other and divide the first chamber 101a into four accommodation areas 102.

[0089] In the embodiment of the present application, the battery assembly 10 comprises a thermal management module 300, and the thermal management module 300 comprises a cooling assembly and a heating assembly. When the battery assembly 10 is in a high-temperature environment, or the temperature of the cell assembly 200 continuously rises, the cooling assembly is used to cool the cell assembly 200, absorb and take away the heat of the cell assembly 200, and reduce the temperature of the cell assembly 200. When the battery assembly 10 is in a low-temperature environment, or the vehicle is just started, in order to make the cell assembly 200 quickly reach the working temperature, the heating assembly is used to generate heat and increase the temperature of the cell assembly 200.

[0090] In some embodiments, the cooling assembly comprises a cold plate 310 arranged at the bottom of the accommodating cavity 101. The heating assembly comprises a heating film 320 bonded to one side of the cold plate 310 facing the cell assembly 200, and the side of the heating film 320 facing the cell assembly 200 is in contact with the bottom side of the cell assembly 200.

[0091] It can be understood that the heating film 320 is bonded between the cold plate 310 and the cell assembly 200, and the upper and lower surfaces of the heating film 320 are bonded with the cold plate 310 and the cell assembly 200 respectively. When the cell assembly 200 needs to be cooled, the cold plate 310 can absorb the heat transferred by the cell assembly 200 through heat conduction, at this time, the heating film 320 does not work. When the cell assembly 200 needs to be heated, the heating film 320 generates heat through electric heating and transfers the heat to the cell assembly 200 to increase the working temperature of the cell assembly 200, at this time, the cold plate 310 does not work.

[0092] For example, the cold plate 310 can adopt the form of refrigerant cooling, that is, the cold plate 310 is filled with refrigerant, and the cooling is realized through the phase change of the refrigerant and the heat of the cell assembly 200 is absorbed.

[0093] It should be noted that in the battery assembly 10 provided in the embodiment of the present application, the heating film 320 is on the bottom side of the cell assembly 200, has a larger contact area, and quickly increases the temperature of the cell assembly 200, thereby improving the internal space utilization of the battery assembly 10 and improving the thermal management efficiency of the battery assembly 10.

[0094] The embodiment of the present application also provides a vehicle, which can comprise the battery assembly 10 in the above technical solutions.
