Description

Technical Field

[0001] The present invention relates to a battery replacement upper frame and a battery replacement battery assembly, belonging to the technical field of battery replacement. Background Art

[0002] New energy battery-swap heavy-duty trucks are in a period of rapid development, and there is no unified technical standard. Various structural forms from different companies have sprung up and are being promoted for use, which has led to incompatibility issues such as structural dimensions and functional interfaces. Limited by the differences in various specifications and standards, it is not conducive to the full utilization of resources and invested infrastructure. Each company has repeatedly invested in construction and competed with each other, which makes it difficult to form a unified and mutually beneficial market promotion and development model, and is not conducive to users reducing procurement costs and improving the convenience of use, maintenance, repair and interchangeability.

[0003] The battery swap assembly is usually divided into a top hoisting part, a battery part and a bottom support part. The total height of the battery swap assemblies of different manufacturers is different, and the required reserved space for the top hoisting part and the bottom support part is also different. If the height of the battery part can be compressed to reserve more top hoisting space and bottom support space, the compatibility of battery swap assemblies between different companies will be greatly improved.

[0004] The existing technology usually adopts direct stacking to reduce the height of the battery part, but this form often requires lifting for installation or disassembly, which easily leads to maintenance difficulties. When the battery pack at the bottom fails, it is often necessary to remove all battery packs above the failed battery pack and a large number of high and low voltage cables and cooling pipes. Summary of the invention

The present invention can achieve the coexistence of a low floor height and a battery tray structure by adding a reinforced bottom plate, a reinforced bottom support and a tray upright support as a reinforcing structure at the connecting position of the tray cross beam and the tray longitudinal beam. During maintenance, the battery can be pulled out from the side with the battery tray structure as a support and guide for targeted disassembly and maintenance without the need to remove them one by one from the top layer, so as to achieve the purpose of reserving more top hanging space and bottom support space and facilitating disassembly and maintenance.

After the cross brace is disassembled and removed, the battery pack can slide out of the wide side area of ​​the frame to the outside of the frame; the ends of the cross brace can be detachably installed on the brace fixing seat on the frame.

[0014] Optionally, the frame further includes a supporting beam, and the supporting beam is arranged at the bottom of the frame along the long side direction of the frame; the battery replacement upper frame further includes: A column diagonal brace, obliquely supported between the supporting crossbeam and the frame column or the reinforcing column; A column reinforcement plate, provided at the connection position between the reinforcement column and the support beam; A compatible pad is used to lock and cooperate with the battery replacement base, and the compatible pad includes: A base, disposed on the supporting beam; A compatible pad is installed on the base, and a groove is formed in the middle of the compatible pad.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example 1

[0024] Combination Figure 1 The present embodiment provides a battery exchange upper frame 1, which includes a square frame body, wherein frame columns 11 are provided at the corners of the frame body, and reinforcing columns 12 are provided in the long side area of ​​the frame body; the frame columns 11 and the reinforcing columns 12 jointly support the frame body, and the reinforcing columns 12 are usually arranged in plurality between the frame columns 11 on both sides, and the plurality of reinforcing columns 12 are distributed in the long side area.

[0025] A top hoisting longitudinal beam 14 is provided in the top area of ​​the frame, and the top hoisting longitudinal beam 14 is used to cooperate with an external hoisting mechanism to hoist the battery swap upper frame 1. Usually, the battery swap upper frame 1 is fixedly connected to the battery swap base 10 by hoisting to achieve locking. A battery area is formed below the top area of ​​the frame, and the battery area is used to place the battery pack. In this embodiment, a plurality of battery tray structures 2 are fixed in the frame, and the plurality of battery tray structures 2 are arranged at intervals along the height direction of the frame to form a plurality of battery layers distributed vertically.

[0026] Combination Figure 1 and Figure 2 The battery tray structure 2 includes a tray crossbeam 21 arranged along the long side of the frame; the number of the reinforcing columns 12 corresponds to the number of the tray longitudinal beams 22. The side of the tray crossbeam 21 away from the reinforcing column 12 is welded with a tray longitudinal beam 22, and the tray longitudinal beam 22 and the tray crossbeam 21 are connected in a T-shape, so that the battery pack can be placed on the top surface of the tray longitudinal beam 22 and the tray crossbeam 21. In order to enhance the structural strength, a reinforcing bottom plate 23, a reinforcing vertical plate 231, a reinforcing bottom bracket 4 and a tray vertical support 3 are added in this embodiment.

[0027] The present embodiment achieves structural reinforcement of the pallet support structure through an additional structure, effectively improving the welding strength at the junction of the pallet crossbeam 21 and the pallet longitudinal beam 22. The pallet uprights 323 angle steels on both sides are then welded and reinforced along the height direction, thereby being able to reduce the height dimensions of the pallet crossbeam 21 and the pallet longitudinal beam 22 while ensuring structural strength. The height of the entire pallet support structure is thin enough, and the height of the entire battery part can reach the layer height achieved by the battery pack stacking form in the prior art. It also has the function of supporting, placing and slidingly guiding the bottom of the battery pack. Each layer of battery packs can be pulled out and slid out along the extension direction of the pallet crossbeam 21 to facilitate the repair of the determined faulty battery pack.

[0028] The following is a specific description of the installation structure. The reinforcing bottom plate 23 is provided at the T-shaped intersection of the pallet cross beam 21 and the pallet longitudinal beam 22. The reinforcing bottom plate 23 is fixedly connected to the pallet cross beam 21 and the pallet longitudinal beam 22. In this embodiment, the reinforcing bottom plate 23 is fixedly connected to the pallet cross beam 21 and the pallet longitudinal beam 22. The reinforcing bottom plate 23 is capable of reinforcing the connection between the pallet cross beam 21 and the pallet longitudinal beam 22. In a specific embodiment, a reinforcing vertical plate 231 is integrally connected to the reinforcing bottom plate 23. The reinforcing vertical plate 231 is provided in the right angle area formed by the T-shaped connection between the pallet cross beam 21 and the pallet longitudinal beam 22. The two sides of the reinforcing vertical plate 231 are respectively welded to the side walls of the pallet cross beam 21 and the pallet longitudinal beam 22.

[0029] In this embodiment, the connection plate formed by the reinforcement bottom plate 23 and the reinforcement vertical plate 231 is a three-sided T-shaped welded reinforcement plate, which can cover the connection area of ​​the pallet cross beam 21 and the pallet longitudinal beam 22 from the bottom. The pallet cross beam 21 and the pallet longitudinal beam 22 can be made of common rectangular tubes, and the three-sided T-shaped welded reinforcement plate can strengthen the structure of the bottom surface and the triangular areas on both sides of the rectangular tube welding structure arranged in a T shape.

[0030] Furthermore, a reinforcing bottom bracket 4 is supported between the reinforcing bottom plate 23 and the reinforcing column 12, and the reinforcing bottom bracket 4 is welded to the reinforcing bottom plate 23 and the reinforcing column 12. The reinforcing bottom bracket 4 is a closed triangular reinforcing bottom bracket, and the reinforcing bottom bracket 4 provides an overall bearing effect by relying on the bottom force-bearing surface of the reinforcing bottom plate 23. The reinforcing bottom plate 23 and the triangular reinforcing bottom bracket 4 can improve the overall welding strength, relieve stress concentration and improve the bearing effect.

[0031] The two sides of the reinforcing base 4 are provided with a pallet support 3, the pallet support 3 has a first vertical surface and a second vertical surface perpendicular to each other, and the pallet support 3 can be made of a common angle steel. The first vertical surface is connected to the side surface of the pallet beam 21 close to the reinforcing column 12, and the second vertical surface is connected to the side surfaces of the two sides of the reinforcing base 4. The connection between the structures is all welding connection.

[0032] In this embodiment, the tray support 3 can achieve a smaller battery layer spacing while ensuring strength, so as to leave reserved space at the bottom and top of the frame, thereby facilitating battery replacement and hoisting compatibility with other battery replacement assemblies. The tray support 3 in this embodiment, by welding angle steel, plays a role of vertical series connection and support for the middle part of the tray beam 21 of each battery tray structure 2 away from the frame column, increasing the force-bearing area of ​​the tray beam 21 and the vertical structural strength and rigidity, and reducing the vibration frequency of the overall structure. The surface of the tray support 3 is regularly perforated, which can be used for integrated routing of pipelines and reasonable bundling and fixing, and plays a role of limiting the movement guidance for the disassembly and assembly positioning action of the battery pack when it is pulled and disassembled along the frame horizontally.

[0033] This embodiment can further improve the load-bearing effect through the tray support 3, so that the overall strength is sufficient when the cross-section of the tray beam 21 is thin enough. After the CAE analysis, the strength is greatly improved, and the anti-resonance effect is also greatly improved. This strengthening will not affect the layered side withdrawal of the battery pack, and the battery part in the frame is low enough to reserve as much space as possible at the bottom and top of the frame to meet the compatibility requirements. At the same time, the overall strength is sufficient, and the strength is greatly improved after the CAE analysis, and the anti-resonance effect is also greatly improved. The workload is smaller during maintenance and repair. There is no need to disassemble and assemble one by one from the top layer to obtain the faulty battery pack, nor is there any need to completely dismantle the top equipment and a large number of pipelines. It is only necessary to disassemble the local pipeline plugs of the corresponding battery pack. This embodiment can make the reserved space at the bottom and top of the frame larger without increasing the height of the battery replacement assembly, has better compatibility, and can also implement a side withdrawal method that is easy to repair. Furthermore, with respect to the test and extraction of the battery pack, in this implementation: Combination Figure 2 A fixing hole 211 is provided on the lower end surface of the tray cross beam 21, and the fixing hole 211 is used to screw in a fastener to fix the battery pack; a welding nut used to connect the battery pack and the tray cross beam 21 is welded in the fixing hole 211 to save the gap between each layer of batteries and maximize the rational use of space.

[0034] When the fixed connection between the battery pack and the pallet cross beam 21 is released, the battery pack can slide on the top surface of the pallet cross beam 21 and the pallet longitudinal beam 22 along the length direction of the frame; Figure 3A guide limit plate 25 is erected on the side wall of the tray cross beam 21 near the reinforcing column 12. The guide limit plate 25 is used to guide the battery pack when the battery pack slides. During the side-drawing process of the battery pack, the guide limit plate 25 can play a limiting role perpendicular to the disassembly and assembly movement direction when the battery pack is pulled out, which simplifies the operation of the construction personnel and allows them to concentrate on the pulling and pulling actions to improve efficiency. The bottom welding edge of the guide limit plate 25 adopts a concave-convex spacing layout to provide a lateral load-bearing effect and improve the welding firmness.

[0035] In order to achieve stable placement and sliding pulling of the battery pack, the first problem is the connection strength of the battery tray structure 2. The structure added in this embodiment has been described in the previous text of this embodiment. The added structure can ensure the structural strength of the battery tray structure 2 and can also reduce the height of the battery layer. In addition, the second problem with pulling out the battery layer is that the battery layer cannot interfere with the structure in the frame when it is pulled out, especially for the frame structure. Most of the structures are connected by welding, and the welds produced by welding can easily hinder the movement of the battery pack.

[0036] In this embodiment, the top surfaces of the pallet crossbeam 21 and the pallet longitudinal beam 22 serve as the placement surface and sliding surface of the battery pack. To avoid sliding interference, no weld seams should be left on the top surfaces of the pallet crossbeam 21 and the pallet longitudinal beam 22. In order to connect the pallet crossbeam 21 and the pallet longitudinal beam 22 in a T-shape, it is usually necessary to weld the two together at the junction of the top surfaces of the pallet crossbeam 21 and the pallet longitudinal beam 22 and leave a weld seam. If you want to avoid the interference of the weld seam with the sliding of the battery pack, you need to perform additional processing on the welding lines after welding, which is inconvenient to operate. In this embodiment, the three-sided T-shaped welded reinforcement plate composed of the reinforced bottom plate 23 and the reinforced vertical plate 231 supports the connection position of the pallet crossbeam 21 and the pallet longitudinal beam 22 from the bottom, so that the welding strength of the structure can be ensured without welding the top surfaces of the pallet crossbeam 21 and the pallet longitudinal beam 22.

[0037] The side surface of the pallet beam 21 close to the reinforcing column 12 is connected to the first vertical surface through a plurality of welding points distributed at vertical intervals. The pallet beam 21 and the pallet support 3 are connected through vertical three-dimensionally distributed welding points instead of welding on the top surface through this staggered welding method. This not only improves the structural strength, but also avoids the need for welding on the top surface through the side staggered welding method. Therefore, without the need for additional processing of the welding lines on the top surfaces of the pallet beam 21 and the pallet longitudinal beam 22, the battery pack will not be affected by irregular welding lines when being pushed and pulled.

[0038] Specifically, the battery tray structure 2 also includes a tray side beam 24, which is connected between the two frame columns 11 in the wide side area of ​​the battery exchange upper frame 1; the two ends of the tray cross beam 21 in the extension direction are connected to the tray side beam 24. In order to enable the tray cross beam 21 to play a supporting and guiding role when the battery is pulled sideways, the tray cross beam 21 cannot be connected close to the reinforcing column 12. There is a certain distance between the tray and the reinforcing column 12. Therefore, the tray cross beam 21 needs to be connected to the tray side beam 24 by welding, and the design reinforcement of the tray cross beam 21 and the tray longitudinal beam 22 away from the column is realized through the welding connection of the aforementioned tray support 3 and the reinforcing support block and the three-sided T-shaped welded reinforcement plate.

[0039] To ensure that the battery pack can slide out of the frame smoothly, Figure 4 In this embodiment, the cross brace 5 arranged on the side of the frame is detachably arranged. In the normal state, the cross brace 5 is fixed to the side of the frame to limit the battery pack in the battery layer to prevent it from slipping; in the disassembled state, the cross brace 5 is removed, and the battery pack in the battery layer can slide out of the frame from the wide side area of ​​the frame. The ends of the cross brace 5 can be detachably mounted on the brace fixing seat 6 on the frame.

[0040] In this embodiment, the cross brace 5 is a detachable X-shaped structure, which can be easily disassembled from the side during the pulling operation. In conjunction with the specific maintenance process, it is only necessary to remove the outer skin of the frame and the cross brace 5 of the X-shaped structure, and then loosen the wires and pipe joints of the battery pack corresponding to the faulty part, so that it can be accurately removed, and then repaired and replaced, and other structures are not affected. The entire frame is also more integrated than the structure of the top layer hoisting in the prior art.

[0041] In a specific embodiment, the cross diagonal brace 5 is fixed to the diagonal brace fixing seat 6 at the corners of the wide side area of ​​the frame by a detachable bolt method, and the cross diagonal brace 5 is fixed to the diagonal brace fixing seat 6 by a detachable bolt structure, thereby improving the overall structural strength and rigidity of the upper frame and reducing the vibration frequency.

[0042] The frame in this embodiment also includes a supporting beam 13, which is arranged at the bottom of the frame along the long side direction of the frame; the battery exchange upper frame 1 also includes a column diagonal brace 7 and a column reinforcement plate 9, and the column diagonal brace 7 is obliquely supported between the supporting beam 13 and the frame column 11 or the reinforcement column 12, and the column reinforcement plate 9 is arranged at the connection position between the reinforcement column 12 and the supporting beam 13 to enhance the structural strength.

[0043] Combination Figure 5 and Figure 6The battery swap upper frame 1 also includes a locking pad 8, which is used to lock and cooperate with the battery swap base 10 of the battery swap assembly. The locking pad 8 includes a base 81 arranged on the supporting beam 13; the base 81 in this embodiment is made of metal and can be firmly fixed to the supporting beam 13 by welding or bolting. The height of the base 81 is designed as needed, which plays a compatible and matching adjustment function for the differences caused by the height dimensions of different supporting beams 13.

[0044] A compatible pad 82 is installed on the base 81. A groove is formed in the middle of the compatible pad 82. The groove surface of the groove can be used as a first matching surface 83 to lock and cooperate with the telescopic lock tongue type mechanism; the surfaces of the compatible pad 82 located on both sides of the groove can be used as a second matching surface 84 to lock and cooperate with the clamping pliers mechanism. The main dimensions of the compatible pad 82 are designed as required and are not limited to a single limit. The second matching surface 84 on the upper surface of the compatible pad 82 is an inclined surface. The inclination or the shape of the surface matches the shape of the lower surface of the pressure mouth of the clamping pliers and the locking movement path. In this case, the middle part of the compatible pad 82 is designed with a locking matching surface for the telescopic lock tongue type locking mechanism as the first matching surface 83. The size, inclination and accurate position of the locking matching surface match the size of the lock tongue structure and the locking positioning position, and it is usually an inclined surface in the opposite direction of the second matching surface 84. The shape of this compatible locking block is only one example. The structural position adjustment changes and shape changes made to meet the same requirements are all within the scope of protection. The design of compatible locking blocks for other different locking structures that meet this idea is also within the scope of protection of this patent.

[0045] The compatible pad 82 is fixed to the base 81 by locking with the fixing bolt 88 through the first bolt hole 85 and the second bolt hole 86. The base 81 can be designed with a weight-reducing cavity structure 87, but the bolt hole needs to avoid the weight-reducing cavity structure 87. When the compatible pad 82 is damaged, the bolt can be removed and then replaced with a good compatible pad 82, or when the compatible locking method changes, it can be replaced with another one to achieve the change of the compatible type. When the size adjustment ability of a base 81 is not enough for compatibility due to the difference in size specifications of the supporting beams 13 of multiple different battery-swap upper frames 1, the height of the locking block can be adjusted by changing the design value of the height of the base 81, or by adding or reducing the middle adapter pad to achieve flexible compatibility with battery-swap mechanisms of different heights and sizes. The battery-swap upper frame 1 also includes grouped flat fixtures for cables and pipelines, single fixtures for wiring harnesses, pipeline line forward layout fixtures, and charging station line fixtures. Each fixture is arranged at various locations of the frame according to the pipeline layout requirements. Example 2

[0046] This embodiment provides a battery swap assembly, which includes the battery swap upper frame 1 described in Embodiment 1, and also includes a battery swap bottom bracket 10, combined with Figure 7The battery replacement base 10 is used to lock and cooperate with the bottom of the battery replacement upper frame 1; in a specific embodiment, combined with Figure 8 The battery exchange base 10 includes a telescopic locking tongue type locking mechanism 101, a guide positioning pin 102, a battery exchange connector support beam 103, a base longitudinal beam 104, an iron pad 105, a shock absorber 106, a locking mechanism size adapter 107, a base cross beam 1010 reinforcement 108, a base subbeam 109, a base cross beam 1010 and a base diagonal brace 1011.

[0047] The bottom support crossbeam 1010 supports the main beam of the battery exchange upper frame 1 and bears the lateral, longitudinal and torsional forces. The specific size is designed as needed and is not limited. Two bottom support longitudinal beams 104 are set at both ends of the two bottom support crossbeams 1010 of the battery exchange bottom support 10. The width size of its cross section can be set according to the actual matching requirements to ensure that the positions of the locking positioning piles at both ends or the positioning piles at the four corners meet the positioning accuracy requirements of the actual matching battery exchange system. The bottom support subbeam 109 is used to be installed on the upper surface of the frame beam, support the bottom support crossbeam 1010, and connect the diagonal braces on both sides on the side. The battery exchange bottom support 10 is firmly fixed to the frame beam through the connecting plate and the connecting bolts. The inner side of the bottom support subbeam 109 has a large opening as a process hole to facilitate the fixing operation of the side bolts. The specific size of this component is not limited. The bottom support diagonal brace 1011 supports the part of the bottom support crossbeam 1010 that exceeds the two sides of the bottom support subbeam 109, and plays a role in auxiliary load-bearing and providing support during lateral tilt and torsion.

[0048] The telescopic lock tongue type locking mechanism 101 includes a guide structure pile (first-level rough guiding and positioning), a telescopic lock tongue mechanism arranged in the pile, and a lock tongue driving structure. The driving structure is divided into various driving forms such as electric, pneumatic, and connecting rod types. The driving type is not limited to a single type. The locking mechanism in this schematic diagram is only used as a case schematic structure.

[0049] The guide positioning pin 102 includes a positioning pin base and a positioning pin pile (second-level precision guide positioning). The size and layout of the positioning pin pile can be adjusted according to the actual matching battery swap upper frame 1 to avoid structural interference with the battery swap upper frame 1. The specific shape and size of the guide positioning pin 102 and the positioning pin base are not uniquely restricted.

[0050] Between the two base cross beams 1010 of the battery swap base 10, there is an array of battery swap connector support beams 103. The positioning size and quantity are determined according to the layout position and fixing method requirements of the battery swap connector. The upper space is used to install the battery swap connector installation system of the base (the battery swap connector has a third-level plug-in precise positioning guide). The installation system maintains consistency in model, pin function definition and positioning size with the actual battery swap system. The battery swap connector installation system can be matched according to the actual battery swap system. This embodiment does not make a unique limitation on size specifications, models and function definitions.

[0051] The iron pad 105 is arranged at corresponding positions on the upper surface of the battery exchange base 10 and the lower surface of the battery exchange upper frame 1 and is fixed by welding. It is mainly responsible for limiting the lower limit of the compression range of the shock absorber 106 and providing gap structural support for the locking part.

[0052] The shock absorber 106 is mostly made of hard rubber or polyurethane and is fixed with bolts to provide vibration and pressure buffering between the battery swap upper frame 1 and the battery swap base 10 as well as dimensional error and dimensional compatibility when locked under force. The designed compression amount = the total thickness of the shock absorber 106 - the sum of the thicknesses of the iron pads 105 on the battery swap upper frame 1 and the battery swap base 10.

[0053] The locking mechanism size adapter 107 is positioned according to the structural dimensions of the supporting beam 13 and its locking pad of the battery swap upper frame 1, so as to serve as the welding adjustment adapter structure required for the adaptation and adjustment of the locking mechanism positioning dimensions of the battery swap base 10. This embodiment does not impose a sole limitation on the specific structural form of the locking mechanism size adapter 1077, thereby achieving the ability to adjust the dimensions as needed to achieve matching compatibility.

[0054] The bottom support cross beam 1010 reinforcement 108 is used for covering and welding the bottom support cross beam 1010, and supplementing welding through plug welding holes, so as to locally reinforce the structure of the bottom support cross beam 1010 at the position of the bottom support sub-beam 109. The thickness of the bottom support cross beam 1010 reinforcement 108 does not exceed the total thickness of the iron pad 105 of the battery exchange bottom support 10 and the battery exchange upper frame 1, so as to ensure that the compression shock absorption and structural adaptation effects of the shock absorber 106 are not affected.

[0055] Combination Figure 8 The battery swap base 10 in this embodiment can be compatible with a variety of actual battery swap systems through the arrangement of the telescopic lock tongue type locking mechanism 101. Specifically, the telescopic lock tongue type locking mechanism 101 of the battery swap base 10 and the locking mechanism of the target battery swap system can form same-position compatibility with the same corresponding arrangement positions, staggered compatibility with some arrangement positions staggered without structural interference, redundant compatibility covering all arrangement positions of the locking mechanism of the target battery swap system and adding extra arrangement positions, or a combination of the aforementioned multiple situations. Example 3

[0056] The present embodiment provides a battery swap method using the battery swap assembly in Embodiment 2. The battery swap upper frame 1 lowers the height of the battery part by adding a reinforcement structure. The bottom and top spaces reserved in the battery swap upper frame 1 are sufficient, so that different types of vehicles or batteries can be compatible through different adaptive arrangements.

[0057] In addition, one car can use multiple types of batteries, but another type of incompatible car can only use the original or individual compatible batteries; some compatible swap stations can be compatible with multiple batteries, but not all types; some battery types are not compatible or cannot be swapped to certain types of vehicles. Therefore, it is necessary to identify and manage compatibility and related control strategies to ensure that the correct car can enter the compatible swap station and provide services, and the battery in the station can be correctly captured and swapped to a compatible matching vehicle.

[0058] Specifically, the method comprises: Step S1, the vehicle's battery replacement controller will collect the vehicle VIN code sent by the VCU or related controller or written by itself as the vehicle identification code; Step S2, collecting the battery assembly code sent by the battery BMS as the battery identification code; Step S3, inputting the compatibility relationship table between the vehicle and the battery assembly into the management platform and the relevant programs of the vehicle and the BMS in advance, and can be updated, expanded or modified in real time as needed; the compatibility relationship table is used to indicate which types of battery swapping battery assemblies the vehicle is compatible with, and at which battery swapping stations the battery swapping battery assemblies can achieve battery swapping compatibility; Step S4: When the vehicle needs to replace the battery, the mobile phone's battery replacement station navigation or other software platforms or channels are used to query. The relevant app or software platform will retrieve the matching information in the compatibility relationship table through the management platform, and determine the nearby battery replacement station that is compatible with the current vehicle and the battery assembly to be replaced according to the battery range that is compatible with the current vehicle, and ensure that the station has a battery replacement battery assembly that can be used for the vehicle and is in a fully charged state. If the battery that can be matched is not fully charged, the current charging progress and completion time will be prompted; Step S5: When the vehicle enters the signal range of the battery swap station, the on-board battery swap controller transmits the vehicle VIN code to the battery swap station through the communication between the vehicle and the battery swap station, or the battery swap station extracts data through various labels identifiable by license plates or scannable codes, and learns the battery type that the vehicle can adapt to and the type of battery currently in use on the vehicle to be replaced; Step S6: When the battery swap station determines through the query system that it is compatible with the vehicle and its currently used battery swap battery assembly, and there is a fully charged battery assembly that can be used for the vehicle in the station, the battery swap is started, the battery assembly on the vehicle is grabbed and placed in the corresponding charging station that is compatible with the battery assembly, and a fully charged compatible battery assembly suitable for the vehicle is grabbed and replaced with the vehicle, and the battery type, status and other related information in the station are updated; the compatible matching data of the battery assembly can be updated as needed, and new compatible types and vehicle and battery coding data can be added; Step S7: The remaining power reminder of the vehicle can be calculated and matched with the local applicable battery swap station and the distance with the corresponding compatible battery to ensure that the vehicle still has enough mileage to go to the appropriate battery swap station when the reminder is given, avoiding the risk of the vehicle stopping due to low power; Step S8: If the driver does not query the compatible battery swap station through any channel and only selects it temporarily, or the battery swap station currently does not have the correct compatible battery for the vehicle, the battery swap station will refuse the vehicle to enter the station and give a specific reason to prompt the driver to go to other stations for replacement; Step S9: When the applicable battery in the station has not been fully charged, but the battery in the vehicle is not enough to go to other stations, the battery swap station allows the vehicle to enter for emergency battery swapping to ensure that the vehicle has enough power to go to the next suitable battery swap station.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
