Detailed Implementation

[0040] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0041] Figure 1 An exploded view of a parking power supply provided as an exemplary embodiment of this application. Figure 2 This is a schematic diagram of the parking power supply provided in an exemplary embodiment of this application after removing its outer casing. Figure 1 and Figure 2 As shown, the parking power supply 100 provided in this application embodiment may include a housing 110 and at least two sets of battery modules 120. The at least two sets of battery modules 120 are disposed inside the housing 110. The housing 110 can protect the battery modules 120 and prevent the battery modules 120 from being damaged by external foreign objects.

[0042] In one embodiment, the number of battery modules 120 can be two, three, four, etc.

[0043] like Figure 1 and Figure 2 As shown, the battery module 120 includes a first end 121 and a second end 122 that are disposed opposite to each other.

[0044] In one embodiment, the first end 121 and the second end 122 are along a first direction (reference). Figure 1 At least two battery modules 120 are arranged relative to each other along the second direction (reference direction). Figure 1 The Y-axis direction is distributed in the middle, and the first and second directions are perpendicular to each other.

[0045] In one embodiment, the aforementioned first and second directions can also be set at acute or obtuse angles.

[0046] like Figure 1 and Figure 2As shown, the parking power supply 100 may further include a battery management system 140, which is located inside the housing 110 and connects to the first terminals 121 of two adjacent battery modules 120. This facilitates, firstly, the battery management system 140 electrically connecting to the electrical components in the two adjacent battery modules 120, enabling convenient control of the charging and discharging processes of the two adjacent battery modules 120; secondly, by integrating the battery management system 140 onto the first terminal 121, and integrating the two adjacent battery modules 120 and their corresponding battery management system 140 within the same housing 110, the space utilization rate inside the housing 110 can be effectively improved, as can the integration level, making it more convenient to carry and transfer.

[0047] In one embodiment, the battery management system 140 can also be connected to the second end 122 of two adjacent battery modules 120. This also achieves the aforementioned technical effects. That is, firstly, it facilitates the electrical connection of the battery management system 140 to the electrical components in the two adjacent battery modules 120, making it easier to control the charging and discharging process of the two adjacent battery modules 120; secondly, the battery management system 140 can be integrated on the second end 122, integrating the two adjacent battery modules 120 and the corresponding battery management system 140 into the same housing 110, which can effectively improve the space utilization rate inside the housing 110, increase the integration level, and make it more convenient to carry and transfer.

[0048] like Figure 1 and Figure 2 As shown, the parking power supply 100 may also include a first mounting plate 150, which connects to the first end 121 of two adjacent battery modules 120, and the battery management system 140 is located on the side of the first mounting plate 150 away from the battery modules 120.

[0049] It should be noted that the first mounting plate 150 can connect two adjacent battery modules 120 into a whole, which facilitates overall transfer and can effectively improve the integration.

[0050] It should be understood that the first mounting plate 150 can serve as the mounting carrier for the battery management system 140. On the one hand, it facilitates the assembly of the battery management system 140; on the other hand, it prevents the battery module 120 from being damaged during the assembly process.

[0051] In one embodiment, the battery management system 140 and the first mounting plate 150 can be positioned by a mating structure of protrusions and grooves, thereby improving the assembly efficiency and accuracy of the battery management system 140.

[0052] like Figure 1As shown, the parking power supply 100 may also include a second mounting plate 160, which connects to the second ends 122 of two adjacent battery modules 120.

[0053] It should be noted that the second mounting plate 160 can connect two adjacent battery modules 120 into a whole, which facilitates overall transfer and can effectively improve the integration.

[0054] In one embodiment, the aforementioned battery management system 140 is disposed on the side of the second mounting plate 160 away from the battery module 120. The function of the second mounting plate 160 is similar to that of the aforementioned first mounting plate 150, as described above.

[0055] In one embodiment, the first mounting plate 150 and the second mounting plate 160 have the same structure, which facilitates processing and manufacturing.

[0056] like Figure 2 As shown, the parking power supply 100 may also include a bracket 170, which is located inside the housing 110 and between two adjacent battery modules 120. The two opposite sides of the bracket 170 are respectively connected to the side walls of the two adjacent battery modules 120.

[0057] It should be understood that, firstly, the bracket 170 can isolate two adjacent battery modules 120, preventing them from directly contacting each other and thus preventing short circuit accidents; secondly, the bracket 170 can improve the assembly stability between two adjacent battery modules 120, connecting them into a whole, facilitating overall transfer, and effectively improving integration.

[0058] In one embodiment, the two opposite sides of the bracket 170 can be fixed to the sidewalls of the two adjacent battery modules 120 by means of bonding, welding or other methods.

[0059] It should be noted that a portion of the outer casing 110 abuts against the bracket 170. In this way, when the outer casing 110 is subjected to external force, the external force can be effectively released during the transmission between the outer casing 110 and the bracket 170, which is less likely to cause damage to the various components, effectively extending the service life of the various components, and effectively improving the overall shock resistance of the parking power supply 100.

[0060] Figure 3 This is a schematic diagram of the parking power supply provided in the open state of an exemplary embodiment of this application. Figure 1 and Figure 3As shown, the outer casing 110 may include a housing 111 and a top cover 113. The housing 111 has an opening 112, and the top cover 113 is located at one end of the housing 111. The top cover 113 can open or close the opening 112.

[0061] In practical applications, the top cover 113 is detached from the housing 111. Before assembly, the top cover 113 is removed from the housing 111 to open the opening 112. Then, the aforementioned battery module 120, battery management system 140, and bracket 170 can be installed into the housing 111. Then, the top cover 113 is assembled onto the housing 111 to close the opening 112.

[0062] It should be understood that both the top cover 113 and the housing 111 can protect the components inside the housing 111 and isolate the internal components from the external environment.

[0063] Figure 4 This is a schematic diagram of the structure of a top cover provided for an exemplary embodiment of this application. Figure 3 and Figure 4 As shown, the inner wall of the top cover 113 is provided with a raised rib 114. It should be understood that the raised rib 114 can enhance the overall structural strength of the top cover 113 and effectively prevent the top cover 113 from deforming.

[0064] It should be noted that after the top cover 113 is assembled with the housing 111, the protruding rib 114 can abut against the side wall of the bracket 170. In this way, when the housing 110 is subjected to external force, the external force can be effectively released during the transmission process of the top cover 113, housing 111 and bracket 170, which is less likely to cause damage to the components and can effectively extend the service life of the components.

[0065] In one embodiment, there are multiple ribs 114, which are arranged in an intersecting manner, with some of the ribs 114 abutting against the side wall of the aforementioned support 170. This not only further increases the structural strength of the top cover 113 but also achieves the aforementioned effect of effectively releasing stress.

[0066] In one embodiment, the parking power supply 100 will be subjected to varying degrees of vibration as it moves with the vehicle. Through the force transmission path between the aforementioned top cover 113, bracket 170 and housing 111, the impact of vibration on the internal battery module 120 can be effectively mitigated, reducing the probability of damage to the battery module 120 due to vibration and effectively extending the service life of the parking power supply 100.

[0067] like Figure 4As shown, the protruding rib 114 may include multiple first nodes 1141 and multiple second nodes 1142, with the multiple first nodes 1141 and multiple second nodes 1142 extending along a first direction (which can be understood as the length direction of the sidewall of the support 170, see reference for details). Figure 4 The nodes are distributed in a cross pattern along the X-axis direction, with the length of the first node 1141 along the first direction being greater than the length of the second node 1142 along the first direction.

[0068] It should be noted that the nodes on the rib 114 (including the aforementioned first node 1141 and second node 1142) can be understood as the intersection points between ribs 114, or as a thickened structure formed by a portion of the rib 114 with a larger cross-sectional area compared to other portions. Therefore, it can be understood that the structural strength of the nodes on the rib 114 is greater than the structural strength of other portions of the rib 114.

[0069] It should be noted that the load on the protruding rib 114 abutting the side wall of the support 170 is usually not uniform along its length (i.e., the aforementioned first direction). Therefore, excessive stress can easily cause problems such as bending and breakage of the protruding rib 114. Therefore, as... Figure 4 As shown, the embodiments of this application employ a structure in which nodes of different sizes are combined with each other (i.e., the aforementioned multiple first nodes 1141 and multiple second nodes 1142 are distributed intersectingly along the first direction), which can improve the shear strength at different locations of the rib 114 and reduce the problem of stress concentration.

[0070] In one embodiment, along the first direction, the number of second nodes 1142 between two adjacent first nodes 1141 can be one, two, three, etc.

[0071] In one embodiment, along the first direction, the number of first nodes 1141 between two adjacent second nodes 1142 is one, two, three, etc.

[0072] It should be noted that multiple first nodes 1141 and multiple second nodes 1142 abut against the sidewall of the bracket 170. When the length of the first node 1141 along the first direction is greater than the length of the second node 1142 along the first direction, the contact area between the rib 114 and the sidewall of the bracket 170 can be effectively increased. In this way, on the one hand, the assembly stability between the rib 114 and the bracket 170 can be improved; on the other hand, during the transmission of force between the rib 114 and the sidewall of the bracket 170, the larger contact area is beneficial to dispersing the load and can reduce stress concentration between the rib 114 and the sidewall of the bracket 170.

[0073] In one embodiment, both the first node 1141 and the second node 1142 are hollow structures. By effectively increasing the contact area between the rib 114 and the side wall of the support 170, the weight of the top cover 113 can be reduced, thereby effectively reducing manufacturing costs.

[0074] Figure 5 This is an exploded view of a battery module provided as an exemplary embodiment of this application. Figure 5 As shown, the battery module 120 may include a plurality of battery cells 123. Specifically, the plurality of battery cells 123 may be arranged along the aforementioned first direction (refer to...). Figure 5 Distribution (in the X-axis direction).

[0075] like Figure 5 As shown, the battery module 120 may also include an insulating component 124. The insulating component 124 is attached to the outer wall of the outermost battery cell 123. The insulating component 124 can block the battery cell 123 from other components, prevent the battery cell 123 from conducting with other components, and avoid short circuit problems.

[0076] like Figure 5 As shown, the battery module 120 may also include a buffer 125. The buffer 125 is attached to the side of the insulating member 124 away from the cell 123. The buffer 125 can buffer external pressure, reduce the impact of external forces on the cell 123, and reduce the probability of the cell 123 being damaged by external forces.

[0077] In one embodiment, the buffer 125 may be selected from MPP (modified polyolefin) foam, silicone, EVA (ethylene-vinyl acetate) foam, etc.

[0078] like Figure 5 As shown, the battery module 120 may further include an end plate 126, which is attached to the side of the buffer 125 away from the insulating member 124. The end plate 126 can protect the battery cell 123.

[0079] It should be noted that the end plate 126 can be the aforementioned first end 121 or second end 122, that is, the aforementioned first mounting plate 150 or second mounting plate 160 can be mounted on the end plate 126.

[0080] In one embodiment, the same battery module 120 includes two insulating components 124, two buffer components 125, and two end plates 126. At the first end 121 of the battery module 120, one set of insulating components 124, buffer components 125, and end plates 126 are stacked according to the positional relationship described above. At the second end 122 of the battery module 120, another set of insulating components 124, buffer components 125, and end plates 126 are stacked according to the positional relationship described above.

[0081] like Figure 5 As shown, the battery module 120 may further include a side plate 127, which is connected to the end plate 126 and covers the sidewalls of multiple battery cells 123. The side plate 127 protects the sidewalls of the multiple battery cells 123 and prevents the battery cells 123 from being damaged by other objects.

[0082] In one embodiment, the side plate 127 is bonded to the side wall of the multiple battery cells 123, which can connect the multiple battery cells 123 into a whole, avoid the multiple battery cells 123 from being separated from each other, and improve the overall integration.

[0083] In one embodiment, for the same battery module 120, there are two side plates 127, and the battery module 120 is along the second direction (reference). Figure 5 Side plates 127 are provided on both sides of the battery module 120 in the Y-axis direction, which can effectively protect both sides of the battery module 120.

[0084] In one embodiment, for a bracket 170 disposed between two adjacent battery modules 120, the side plates 127 of the two adjacent battery modules 120 can be respectively bonded to the opposite sides of the bracket 170 to achieve relative fixation.

[0085] In one embodiment, such as Figure 5 As shown, the side plate 127 and the end plate 126 can be relatively fixed by fasteners 133 such as bolts and screws.

[0086] like Figure 5 As shown, each cell 123 is provided with a terminal post 128. The battery module 120 may also include a busbar assembly 129. The busbar assembly 129 is disposed on the top wall of multiple cells 123 and is electrically connected to multiple terminals 128.

[0087] In practical applications, the busbar assembly 129 can connect multiple battery cells 123 in series or in parallel to ensure uniform current distribution among the battery cells 123, prevent overload of some battery cells 123, and improve safety performance. In addition, the busbar assembly 129 can act as a heat conductor to transfer the heat generated by the battery cells 123 to the liquid cooling plate, thereby improving the heat dissipation efficiency of the battery cells 123.

[0088] like Figure 5 As shown, the battery module 120 may also include a cover plate 131 and an insulating mounting base 132. The cover plate 131 is disposed on the side of the busbar assembly 129 away from the battery cell 123. The cover plate 131 can protect the busbar assembly 129 and the battery cell 123 and prevent external objects from damaging the busbar assembly 129 and the battery cell 123.

[0089] like Figure 5As shown, the battery module 120 may also include an insulating fixing seat 132, which is sleeved on the outer wall of the terminal post 128. The insulating fixing seat 132 can fix the terminal post 128 and prevent the terminal post 128 from shaking.

[0090] It should be noted that the connection between the insulating mounting base 132 and the cover plate 131 can, on the one hand, improve the assembly stability of the insulating mounting base 132; on the other hand, the insulating mounting base 132 can isolate the pole post 128 and the cover plate 131, preventing the pole post 128 from directly contacting the cover plate 131 and avoiding short circuit problems.

[0091] The following is combined with Figures 1 to 5 Taking two battery modules 120 as an example, the assembly process of the parking power supply 100 will be introduced.

[0092] First, assemble one of the battery modules 120. Place multiple battery cells 123 on a special workbench and use structural adhesive to bond and fix the multiple battery cells 123, which are distributed along a first direction. On the outermost two battery cells 123, attach an insulating component 124, a buffer component 125, and an end plate 126 sequentially to their outer walls. Attach side plates 127 to the opposite side walls of each battery cell 123 along a second direction, and use fasteners 133 to fix both side plates 127 to the end plates 126. Then, place a busbar assembly 129 on top of the multiple battery cells 123 and fix the busbar assembly 129 to the terminal post 128. Finally, cover the module with a cover plate 131.

[0093] Repeat the above steps to assemble another battery module 120. Then, assemble the bracket 170 between the two battery modules 120, and use structural adhesive to bond both sides of the bracket 170 to the side plates 127 of the two battery modules 120 respectively.

[0094] The first mounting plate 150 is fixed to the end plate 126 of the first end 121 of the two battery modules 120 using bolts, and the second mounting plate 160 is fixed to the end plate 126 of the second end 122 of the two battery modules 120 using bolts. Then, the battery management system 140 is fixedly connected to the first mounting plate 150 or the second mounting plate 160.

[0095] The battery module 120, bracket 170 and battery management system 140 are installed into the housing 111, and then the top cover 113 is put on so that the protruding ribs 114 of the top cover 113 abut against the side wall of the bracket 170. Finally, the top cover 113 is fixed to the housing 111 with bolts.
