Detailed Implementation

[0034] Currently, the commonly used standard battery box adopts a scheme where the integrated panel is mounted on the top cover, and all electrical components are mounted on the integrated panel. Furthermore, this integrated panel mounting method is generally an internal installation; all electrical components are pre-installed on the integrated panel, then the top cover is installed, and finally the integrated panel is mounted on the top cover.

[0035] The inventors discovered that if the internal BMS (Battery Management System) malfunctions, the entire battery pack needs to be completely disassembled, the top cover removed, and the BMS replaced.

[0042] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0043] The following describes in detail the overall structure, working principle, and technical effects of the electrical mounting plate 100 and battery box 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0044] Please refer to Figure 1 The electrical mounting plate 100 and battery box 010 provided by this utility model can be applied to new energy vehicles, such as heavy trucks, mining trucks, and buses. Of course, they can also be applied to energy storage systems.

[0045] Please refer to Figure 1 and Figure 2 The battery box 010 proposed in this embodiment includes an electrical mounting plate 100 and a front panel 200, wherein the electrical mounting plate 100 is detachably mounted on the front panel 200.

[0046] It is understandable that the electrical mounting plate 100 is detachably mounted on the front bulkhead 200, which facilitates partial disassembly during later maintenance, saving manpower and resources.

[0047] In this embodiment, please refer to Figure 1The battery box 010 includes a lower box 300, a front panel 200, a rear panel 400, an upper box 500, and a battery module 600; the front panel 200 is sealed on the front side of the lower box 300; the rear panel 400 is sealed on the rear side of the lower box 300; the lower box 300, the front panel 200, and the rear panel 400 form a mounting cavity for accommodating the battery module 600, and the battery module 600 is fixed to the top wall of the lower box 300; the upper box 500 is fixed to the lower box 300, the front panel 200, and the rear panel 400 to form the battery box 010 as a whole.

[0048] In this embodiment, the battery box 010 includes a lower box body 300.

[0049] In this embodiment, the lower housing 300 includes a bottom plate and two side beams; the bottom plate is a rectangular plate structure, and side beams are provided on both opposite sides of the bottom plate. A front panel 200 is provided on the front side of the lower housing 300, and two drainage parts 310 for mounting water nozzles 320 are provided at positions opposite to the front panel 200. The two drainage parts 310 are respectively fitted to the two side beams.

[0050] The base plate has a flow channel for circulating coolant to cool the working battery module 600; the drain section 310 has a channel that connects the water nozzle 320 and the flow channel.

[0051] Understandably, this design of the lower housing 300 results in a compact structure that doesn't waste the overall space of the battery box 010.

[0052] In this embodiment, the battery box 010 includes a front panel 200.

[0053] The front panel 200 has an opening 210, and the electrical mounting plate 100 is installed at the opening 210.

[0054] In this embodiment, please refer to Figure 1 and Figure 2 The front bulkhead 200 is located on the front side of the lower box 300; the front bulkhead 200 is located on the front side of the bottom plate of the lower box 300, and the two sides of the front bulkhead 200 are respectively connected to the side beams on both sides of the lower box 300.

[0055] Furthermore, both sides of the front bulkhead 200 are provided with flow guide installation ports, and the flow guide part is disposed in the flow guide installation port and pressed against the front bulkhead 200. The flow guide installation port is configured to match the shape of the flow guide part and is located on the lower sides of the front bulkhead 200.

[0056] Understandably, this configuration of the front panel 200 and the drainage section will not interfere with the wiring cables of the electrical mounting plate 100 when the water nozzle 320 is connected to the external liquid cooling pipeline.

[0057] In this embodiment, the battery box 010 includes an electrical mounting plate 100.

[0058] Please refer to Figure 2 and Figure 3 The present invention proposes an electrical mounting plate 100, which is connected to the front panel 200. The electrical mounting plate 100 is provided with a first mounting platform 110, which is connected to the electrical mounting plate 100. The inner side of the first mounting platform 110 is provided with a first mounting groove 111, and at least a battery management system module 120 is provided in the first mounting groove 111. The battery management system module 120 is connected to the inner wall of the first mounting platform 110.

[0059] Understandably, by setting a first mounting platform 110 on the electrical mounting plate 100, with a first mounting groove 111 on the inner side of the first mounting platform 110, and placing the battery management system module 120 in the first mounting groove 111 of the first mounting platform 110, space can be fully utilized, and the magnetic field generated by the current on other components will have minimal interference to the battery management system module 120, thereby improving the pass rate of EMC (Electromagnetic Compatibility) testing. Furthermore, by setting the electrical mounting plate 100 on the front bulkhead 200, the electrical mounting plate 100 can be detachably installed on the front bulkhead 200, facilitating partial and individual disassembly when maintenance of the battery management system module 120 is required in the future, saving manpower and resources.

[0060] In this embodiment, the electrical mounting plate 100 includes a battery management system module 120.

[0061] Please refer to Figure 6 The battery management system module 120 is the control board and related electronic components of the BMS (Battery Management System).

[0062] In this embodiment, please refer to Figure 1 The electrical mounting plate 100 is used for detachable connection with the opening 210 of the front bulkhead 200. The electrical mounting plate 100 is a plate structure, and its shape matches the shape of the opening 210 of the front bulkhead 200, for example, it is a rectangular plate. The electrical mounting plate 100 is connected and fixed to the front bulkhead 200 by connectors.

[0063] Along the inner edge of the opening 210, the front bulkhead 200 has multiple spaced first mounting holes; the electrical mounting plate 100 has multiple spaced second mounting holes around its perimeter. Connectors pass through the first and second mounting holes to connect and fix the electrical mounting plate 100 to the front bulkhead 200. Connectors can be screws, bolts, etc.

[0064] It is worth mentioning that, please refer to Figure 2 and Figure 3 The top of the front panel 200 is connected and fixed to the upper housing 500 by multiple rivet nuts 510. After the rivet nuts 510 pass through the top of the upper housing 500 and the front panel 200, when the lower end of the rivet nuts 510 extends to the electrical mounting plate 100, the lower end of the rivet nuts 510 interferes with and is incompatible with the top of the electrical mounting plate 100.

[0065] Therefore, in this embodiment, multiple notches 180 are provided on the top side of the electrical mounting plate 100 relative to the rivet nut 510 of the front panel 200. This arrangement can avoid the end of the rivet nut 510, preventing the electrical mounting plate 100 and the rivet nut 510 from interfering with each other. At the same time, the electrical mounting plate 100 can be designed to be larger, making it easier to arrange the electrical components 150.

[0066] In this embodiment, the electrical mounting plate 100 includes a first mounting platform 110.

[0067] In this embodiment, please refer to Figure 3 and Figure 4 The first mounting platform 110 is disposed on the electrical mounting plate 100. The inner side of the first mounting platform 110 is provided with a first mounting groove 111. The first mounting groove 111 is disposed relative to the first mounting platform 110. At least one battery management system module 120 is disposed in the first mounting groove 111. The battery management system module 120 is connected to the inner wall of the first mounting platform 110.

[0068] The electrical mounting plate 100 can be formed by sheet metal processing to create a first mounting platform 110 and a first mounting groove 111, thus forming an interlaced convex bulge and groove on the electrical mounting plate 100 and mounting other corresponding components, thereby making full use of space and improving space utilization.

[0069] Understandably, since the battery management system module 120 is located in the first mounting slot 111 and enclosed within the first mounting platform 110, the magnetic field generated by the current on the electrical components 150 (e.g., manual maintenance switch 151, positive terminal box 152, and negative terminal box 153) mounted on the second mounting platform 140 will have minimal interference with the battery management system module 120, thereby improving the pass rate of EMC (Electromagnetic Compatibility) tests.

[0070] Optionally, a fire detector 160 can also be installed in the first mounting slot 111, and the fire detector 160 is connected to the inner wall of the first mounting platform 110. This arrangement allows the fire detector 160 and the battery management system module 120 to share the first mounting slot 111 and the mounting bracket 130, which can save space and materials.

[0071] Alternatively, please refer to Figure 3 An explosion-proof valve 170 can also be installed on the outer wall of the first mounting platform 110.

[0072] In this embodiment, please refer to Figure 6 The battery management system module 120 is tilted within the first mounting slot 111. The battery management system module 120 can tilt downwards or upwards. This arrangement saves space within the first mounting slot 111.

[0073] In this embodiment, please refer to Figure 4 and Figure 5 The first mounting slot 111 has two oppositely arranged mounting brackets 130 inside. The mounting brackets 130 are connected to the inner wall of the first mounting platform 110. The battery management system module 120 is mounted on the two mounting brackets 130.

[0074] Alternatively, please refer to Figure 4 and Figure 5 The mounting bracket 130 includes a first connecting arm 131 and a second connecting arm 132 connected to each other. The first end of the first connecting arm 131 is connected to the inner wall of the first mounting platform 110, and the second end of the first connecting arm 131 is connected to the second connecting arm 132. The first connecting arm 131 and the second connecting arm 132 are arranged vertically.

[0075] The second connecting arm 132 is perpendicular to the first connecting arm 131, thereby forming a mounting end face 1321 on the side wall of the second connecting arm 132. This allows the battery management system module 120 to be mounted on the mounting end face 1321 of the second connecting arm 132.

[0076] Please refer to Figure 4 If the side connecting the first connecting arm 131 and the second connecting arm 132 is a hypotenuse, then the first connecting arm 131 can be a right-angled triangular plate; this allows the battery management system module 120 to be tilted within the first mounting slot 111.

[0077] Alternatively, please refer to Figure 4 and Figure 5When the fire detector 160 needs to be installed on the mounting bracket 130, the second connecting arm 132 can be extended and widened to increase the width of its mounting end face 1321, so that the second connecting arm 132 can simultaneously fix the fire detector 160 and the battery management system module 120.

[0078] Among them, the battery management system module 120 is installed on two mounting brackets 130; the battery management system module 120 is installed on one side of the mounting end face 1321 of the second connecting arm 132 of one of the mounting brackets 130, and the fire detector 160 is installed on the other side of the mounting end face 1321 of the second connecting arm 132.

[0079] This configuration allows the mounting bracket 130 to accommodate two types of components, saving materials.

[0080] Alternatively, please refer to Figure 4 The mounting end face 1321 of the second connecting arm 132 is provided with a positioning post 1322 for positioning and mounting the battery management system module 120 and the fire detector 160.

[0081] The positioning post 1322 is equipped with a nut for easy positioning.

[0082] Alternatively, please refer to Figure 4 Both mounting brackets 130 are equipped with wire harness brackets 133, and the wire harness brackets 133 are provided with mounting holes 1331 for installing wire harnesses.

[0083] The wire harness bracket 133 can extend along one side of the second connecting arm 132 and bend to form a corresponding bracket structure.

[0084] In this embodiment, the electrical mounting plate 100 includes a second mounting platform 140.

[0085] In this embodiment, please refer to Figures 2-6 The second mounting platform 140 is set on the electrical mounting plate 100, and electrical components 150 are installed on the outside of the second mounting platform 140. The second mounting platform 140 and the first mounting platform 110 are arranged side by side, and the height of the second mounting platform 140 is less than the height of the first mounting platform 110.

[0086] The second mounting platform 140 has a second mounting groove on its inner side for accommodating and mounting electrical components 150.

[0087] The electrical mounting plate 100 can be formed by sheet metal processing to create a first mounting platform 110, a first mounting groove 111, and a second mounting plate. This allows the electrical mounting plate 100 to form interlaced protrusions and grooves, and to install other corresponding components, thus making full use of space and improving space utilization.

[0088] In this embodiment, please refer to Figure 3 The electrical component 150 includes at least a manual maintenance switch 151, a positive terminal box 152, and a negative terminal box 153; the positive terminal box 152 and the negative terminal box 153 are arranged side by side, and the manual maintenance switch 151 is located on one side of the positive terminal box 152 and the negative terminal box 153.

[0089] This arrangement saves installation space for electrical components 150; at the same time, the cable terminals of the positive terminal box 152 and the negative terminal box 153 face the same side, which saves cable size and reduces overall wiring costs.

[0090] In this embodiment, please refer to Figure 2 The positive terminal box 152 and the negative terminal box 153 are positioned near the drain section 310, and the water nozzle 320 is positioned between the positive terminal box 152 and the negative terminal box 153. This prevents interference between the external liquid cooling pipes of the water nozzle 320 and the wiring cables of the positive terminal box 152 and the negative terminal box 153.

[0091] It is worth mentioning that the heights of the first mounting platform 110 and the second mounting platform 140 should be selected according to the components to be installed, so that the overall height of the second mounting platform 140 after the components are installed is less than or equal to the overall height of the first mounting platform 110 after the components are installed. This arrangement of the electrical mounting plate 100 results in high overall space utilization.

[0092] It is worth mentioning that the electrical mounting plate 100, the first mounting platform 110 and the second mounting platform 140 are integrally formed structures of metal plates (such as aluminum plates), which can be integrally formed by sheet metal.

[0093] In summary, the electrical mounting plate 100 and battery box 010 provided in this embodiment of the present invention, by setting a first mounting platform 110 on the electrical mounting plate 100 and providing a first mounting groove 111 on the inner side of the first mounting platform 110, and placing the battery management system module 120 in the first mounting groove 111 of the first mounting platform 110, can make full use of space on the one hand, and the magnetic field generated by the current on other components will have very little interference to the battery management system module 120, which can improve the pass rate of EMC (Electromagnetic Compatibility) test; and by setting the electrical mounting plate 100 on the front panel 200, the electrical mounting plate 100 can be detachably installed with the front panel 200, which facilitates partial and individual disassembly when the battery management system module 120 needs to be maintained in the future, saving manpower and resources.

[0094] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
