Description

Technical Field

[0001] The present invention relates to the field of new energy vehicle charging, and in particular to a charging control method and a charging control device for a rail-mounted vehicle charging device. Background Art

[0002] By the end of 2023, China will have the world's largest number of new energy vehicles on the road. However, due to the current state of domestic parking, new energy vehicles will continue to rely on shared charging stations for recharging. With the country's vigorous promotion of public charging stations, the ratio of charging stations to parking spaces in public parking lots will continue to increase. However, due to the current structure and distribution of charging stations, the cost per parking space is increasing. For example, the floor space occupied by charging stations, the number of charging stations, and standby power consumption are all factors that lead to high costs and energy consumption per parking space, and low turnover rates. Therefore, there is an urgent need for low-cost, low-resource-intensive, and high-efficiency charging stations.

[0003] The structural and site characteristics of existing public charging piles determine that various problems will arise when car owners (vehicle users) charge their cars, such as too few dedicated charging parking spaces, gasoline vehicles occupying parking spaces, charging overtime occupying parking spaces, and queuing for charging, which makes the charging experience of car owners poor and wastes public resources.

[0004] While new energy-recharging solutions, such as battery swap stations and wheeled charging robots, have emerged on the market to address these issues, their inherent characteristics hinder widespread adoption. Specifically, battery swap stations require large floor space, have limited battery backup per station, support limited vehicle models, and preclude the construction of underground parking lots. Wheeled charging robots, all of which are self-contained, utilize charging piles. The high cost of each pile also creates safety and legal risks when operating in large areas, as they must navigate numerous obstacles.

[0005] Currently, there are also rail-mounted charging robots that attempt to solve the problems of existing pile-type charging equipment, such as the rail-mounted charging equipment and charging method described in the Chinese invention patent application with publication number CN114954079A. However, if the ratio of charging piles is insufficient, it will cause car owners to wait too long in the parking space or fail to charge. Summary of the Invention

[0017] In summary, the beneficial effects of the present invention are at least in the following aspects:

[0018] 1. The present invention utilizes the high mobility of rail-mounted charging equipment (charging robot) to solve the problems of low utilization rate of traditional charging facilities and large workload of ground modification of parking spaces. It can effectively reduce the ratio of charging piles to parking spaces while improving the efficiency and convenience of new energy vehicles in finding charging piles, thereby improving the asset utilization rate of charging piles.

[0019] 2. This invention can cover all parking spaces in a large parking lot, eliminating the need for dedicated parking spaces for new energy vehicles. It can also accommodate mixed parking for gasoline and electric vehicles.

After completing the plug-in and confirming the parking space on the system, he can leave the scene. There is no need to wait in the parking space for the charging host to arrive, which saves the owner's time. In particular, when there are not enough charging hosts and the previous ones are still charging and need to queue for charging, the owner does not need to wait on site. When there is an idle host, the system will automatically drag the charging host to this parking space and automatically connect with the charging base station to power the charging gun and replenish the vehicle, thereby improving the user's charging convenience and improving asset utilization.

DETAILED DESCRIPTION

[0032] The exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement of components, numerical representations, and numerical values ​​described in these embodiments does not limit the scope of the present invention. For simplicity, the same symbols or numbers are used for the same structural parts or steps, and their descriptions are omitted.

[0033] [Structure of the automobile charging system of the present invention]

[0034] The following reference Figure 1A and 1B The structure of the rail-mounted vehicle charging system of the present invention will be described. This vehicle charging system comprises: a frame-type guide rail structure 1 arranged on top of a parking lot; a rail-mounted vehicle charging device 10; multiple charging base stations 4 suspended above parking spaces via the guide rail structure 1 in a manner corresponding to the parking spaces; and charging terminals 5 arranged corresponding to the parking spaces and capable of accommodating charging guns. The vehicle charging device 10 comprises a charging host mounting platform 2 that can be mounted and operated on the running guide rails; and a charging host 3 that is removably mounted below the charging host mounting platform.

[0035] like Figure 1A and Figure 1B As shown, the charging terminal 5 includes a charging gun holder 501, which is fixed on the charging terminal for receiving the charging gun, and preferably the charging terminal 5 can be mounted on a column 502 on the charging base station 4 in a hanging manner (such as Figure 1B as well as Figure 6A and 6B In addition, the charging terminal 5 can be installed on the ground of the parking lot, for example, it can be installed on the ground column type on the column 502, or it can also be installed on the wall.

[0036] When the vehicle to be charged is parked in a parking space (charging space or target parking space) on the side of any idle charging base station 4, the user (such as the car owner) can remove the charging gun from the charging terminal 5 and insert it into the charging port of the vehicle to prepare for charging. The user can issue a charging instruction by operating a user terminal or an on-board terminal such as a mobile phone, or the car charging system receives a charging instruction issued by the user by operating a user terminal or an on-board terminal after detecting that the charging gun is inserted into the charging port of the vehicle. After receiving the charging instruction, the charging host mounting platform 2 mounts the adjacent idle charging host 3, and transports the charging host 3 to the charging base station (target charging base station) 4 corresponding to the target parking space, and electrically connects the charging host 3 to the target charging base station 4, so that the charging host 3 can supply power to the vehicle through the charging base station 4 and the connected charging gun 407.

[0037] The following reference Figure 1A The specific structure of the guide rail structure 1 is described. Figure 1A As shown, the guide rail structure 1 comprises: a running guide rail 101 arranged above the parking spaces of the parking lot and suspended in a through-type manner; and a suspension frame 103 for fixing the running guide rail 101 on the top of the parking lot, and the suspension frame 103 is installed above the covered parking spaces. As an example, the cross section of the running guide rail 101 shown in the present invention is an I-shaped (such as Figure 1A 、 Figure 3 as well as Figure 6B As shown), other shapes or structures can obviously be used.

[0038] The charging base stations 4 can be arranged in a one-to-one correspondence with the parking spaces, above each parking space along the running rails. Other arrangements are also possible, such as a two-to-one arrangement between two parking spaces with vehicles parked rear-to-rear, or a three-to-one or four-to-one arrangement depending on the specific parking space layout, or a combination of two or more of the above arrangements.

[0039] The charging host mounting platform 2 of the vehicle charging device 10 can be mounted on the travel rail of the rail structure 1 and can communicate with the server via a network to travel between the charging base stations along the travel rail 101 according to the server's instructions.

[0040] The specific structures of the charging base station and the vehicle charging device included in the vehicle charging system of the present invention are described in detail below.

[0041] [Structure of the Charging Base Station of the Present Invention]

[0042] The following reference Figure 6A and Figure 6B , the structure of the charging base station according to the present invention is described. The charging base station 4 includes: a support frame 400, a static plug-in module 401, a locking track 402, a parking fixed beam 403, and a communication and power supply module 404. Among them, the support frame 400 adopts a frame structure, and the side frame 400W of the support frame 400 away from the walking track 101 extends downward, and the static plug-in module 401 is installed on the extended part of the side frame 400W. As a preferred example, Figure 6B The static plug-in module 401 is located in the center of the side frame 400W. Obviously, the static plug-in module 401 can also be located on one side of the side frame 400W close to the edge, as long as it can correspond to the position of the matching dynamic plug-in.

[0043] The axis of the locking rail 402 is perpendicular to the travel rail 101 and is arranged at the bottom of the support frame 400 to carry and limit the charging host. The locking rail 402 has a locking hole 402H opened in the axial direction close to one end of the travel rail 101, which can be docked with the positioning module of the charging host (which will be described later) to form a locking state between the charging host and the charging base station, thereby ensuring that the host will not detach from or fall from the base station. The parking fixed beam 403 can adopt a straight beam column structure, which is arranged at the top of the support frame 400 in a manner parallel to the locking rail 402, and extends to one side of the travel rail 101 and is fixedly connected to the travel rail 101 above the travel rail 101. The parking fixed beam is used as a locking mechanism when the charging mounting platform is parked.

[0044] The communication and power supply module 404 is fixed to the bottom surface of the parking fixed beam 403 and close to the travel track 101. It can cooperate with the positioning module of the charging host mounting platform 2 to form a locked state. In this state, the communication and power supply module 404 of the charging base station 4 and the communication and power supply module of the charging host mounting platform 2 are docked to form an electrical connection and enable mutual communication. In addition, the static plug-in module 401 is docked with the dynamic plug-in module on the charging host to form an electrical connection.

[0045] The charging base station 4 also includes a charging gun terminal socket 405 arranged on the side frame 400W. The charging base station 4 is connected to the charging line 406 through the charging gun terminal socket 405 to provide power supply, communication control and other capabilities for the charging gun 407.

[0046] [Structure of the vehicle charging device of the present invention]

[0047] The following reference Figure 1A 、 Figure 1B as well as Figure 2 and Figure 3 The structure of the vehicle charging device of the present invention will now be described. The vehicle charging device 10 according to the present invention comprises a charging unit mounting platform 2 and a charging unit 3 removably mounted below the charging unit mounting platform 2. In operation, the charging unit mounting platform 2 is suspended below the frame's running rails 101. The charging unit mounting platform 2 can move between various charging base stations 4 along the running rails 101 of the frame's rail structure 1, either with or without the charging unit 3. The mounted charging unit 3 can be pushed to a charging base station 4 to be unloaded.

[0048] The specific structures of the various parts of the vehicle charging device of the present invention are described in detail below.

[0049] [Structure of the charging host mounting platform of the present invention]

[0050] The following reference Figure 4A and Figure 4B , describing the structure of the charging host mounting platform. Specifically, the charging host mounting platform 2 includes a platform body 200. Two walking modules 201 are arranged on the top surface of the platform body 200. As a preferred example, two walking modules 201 (201A and 201B) are arranged on the top surface of the platform body 200 in a symmetrical manner along the longitudinal direction of the platform body 200 (a direction parallel to the walking guide rail 101 in the mounted state). Obviously, the number and arrangement of the walking modules 201 are not limited to this, and other numbers and arrangements may also be used.

[0051] As a preferred example, in this embodiment, each traveling module 201 utilizes roller assemblies symmetrically arranged along the transverse direction of the platform body 200 (in the direction perpendicular to the traveling rails 101 when mounted). In the mounted state, the traveling rails 101 are tightly held in the center of each wheel assembly. Obviously, the number of roller assemblies is not limited to two; for example, more than two can be used. The arrangement of the roller assemblies is also not limited to the above arrangement.

[0052] The travel module 201 also includes a travel motor 201C. The wheels connected to the travel motor 201C are the driving wheels 201B, while the wheels not connected to the travel motor are the driven wheels 201A. As a preferred example, the travel modules 201 on both sides of the longitudinal front are equipped with motors. In operation, the driving and driven wheels of the travel modules each clamp the travel rails between them. Driven by the travel motor, the driving wheels move forward and backward along the travel rails 101, carrying the charging unit mounting platform 2.

[0053] The charging host mounting platform 2 also includes a positioning module 203 located on the top surface of the platform body 200 and a communication and power supply module 202 arranged on top of the positioning module 203. When the positioning module 203 is locked with the parking beam 403 of the charging base station 4, the communication and power supply module 202 connects with the communication and power supply module on the parking beam of the charging base station to draw power and communicate. The positioning module 203 is a clamping mechanism that uses a screw drive to extend and retract to clamp the parking beam 403, thus locking the charging host mounting platform 2 with the charging base station 4.

[0054] The platform body 200 may be equipped with components such as a rechargeable battery, a processor, and memory. When the charging host mounting platform 2 is not connected to the charging base station 4, the rechargeable battery can provide power for the charging host mounting platform 2 to operate on the track, send and receive commands and information, detect obstacles, perform obstacle avoidance control, and perform positioning. The memory may store computer programs for various operations or processes of the charging host mounting platform 2, such as track travel, power supply, communication, mounting and unmounting a charging host, and locking the charging base station. The processor executes the computer programs stored in the memory to implement the corresponding processing.

[0055] The charging host mounting platform 2 also includes a push-and-retract module 205 and a travel track 206 disposed at the bottom of the platform body 200. Furthermore, a limiter assembly 204, a movable mechanism, is provided at the end of the push-and-retract module 205 facing away from the charging base station. In this embodiment, the limiter assembly 204 is a spring-loaded structure, but other limiter structures are readily acceptable.

[0056] Furthermore, the limit assembly 204 matches the positioning module of the charging host 3. When the limit assembly 204 is opened (by ejecting the latch in a protruding manner), it pushes the positioning assembly 303 of the charging host 3 outward and locks it, causing the push-and-receive module 205 to enter a locked state with the charging host 3. As the push-and-receive module 205 continues to push the charging host 3 from the charging host mounting platform 2 toward the charging base station 4 (or retract it from the charging base station 4 toward the charging host mounting platform 2), the charging host 3 can be unlocked from the charging host mounting platform 2 (or the charging base station 4). When the charging host mounting platform 2 and the charging base station 4 are locked, the running track 206 mates with the locking track 402 of the charging base station 4 to form a horizontal track, allowing the push-and-receive module 205 to move the charging host 3 between the charging host mounting platform 2 and the charging base station 4.

[0057] To release the locking state between the push-and-retract module 205 and the charging host 3 , the limiting assembly 204 is released and the positioning assembly 303 of the charging host is retracted inwardly along the longitudinal direction, so that the limiting assembly 204 is released from the locking state between the positioning assembly 303 of the charging host 3 .

[0058] In addition, the charging host mounting platform 2 also includes a charging base station location identifier 207 and an obstacle detector 208 mounted on the outer periphery of the platform body 200. The base station location identifier 207 can be placed on the side of the platform body 200 of the charging host mounting platform 2 facing the charging base station. The base station location identifier 207 can identify the QR code on the charging base station side to determine the location of the charging base station, thereby performing a relative positioning operation between the charging host mounting platform 2 and the base station. When the charging host mounting platform 2 moves on the walking track, the base station location identifier 207 is used to perform a rough positioning relative to the charging base station to assist in its own positioning on the track, as well as to perform a preliminary relative positioning relative to the target charging base station. The obstacle detector 208 can be a sensing device mounted on the outer surface of the platform body. The sensing device can be, for example, a camera, a distance sensor, etc. As a preferred method, for example, the obstacle detector 208 can be arranged on the end faces on both sides of the longitudinal direction of the platform body (the direction parallel to the walking track 101 in the mounted state) and on the bottom surface of the platform body near the outer edge, so as to perform environmental sensing and obstacle avoidance control when the platform moves on track through the perception results of the environment by the sensing component.

[0059] In summary, since the charging host mounting platform capable of mounting a charging host can move along the guide rails above each parking space and between charging base stations in the parking lot, the charging host can not only act as a mobile charging pile, moving between charging base stations and charging itself when idle, but can also respond to vehicle charging requests at each parking space and power vehicles at different charging base stations corresponding to different target parking spaces. Therefore, the vehicle charging equipment of the present invention has high mobility, can effectively reduce the charging host to parking space ratio, improve the efficiency and convenience of new energy vehicles in finding charging piles, and improve the utilization rate of the charging host.

[0060] [Structure of the charging host of the present invention]

[0061] The following reference Figure 5A and Figure 5B, describing the structure of the charging host. The charging host 3 includes a positioning component 303, which is located at the top of the charging host and is facing away from the side of the charging base station in the lateral direction (the direction perpendicular to the walking guide rail in the mounted state). As a preferred example, it adopts a latch structure that matches the limit component 204, but it is obviously not limited to this, and other interlocking structures that match the limit component 204 can also be adopted. The positioning component 303 is operable to cooperate with the limit component 204 of the charging host mounting platform 2. When the limit component 204 is opened (extended outward), the positioning component 303 is pushed outward, so that the positioning component 303 is locked with the limit component 204 to achieve the locking of the pushing and receiving module 205 and the charging host 3; and when the limit component 204 is released and retracted, it is unlocked with the positioning component 303, so that the charging host and the locking track on the charging host mounting platform 2 or the charging base station form a locked state. The positioning module of the charging host cooperates with the limiting component of the charging host mounting platform to form a locking fixation between the charging host and the pushing and receiving module, the locking track on the charging base station, and the charging host mounting platform.

[0062] The charging host 3 also includes: two sets of walking modules 302 installed on its left and right sides, which enable the charging host to move on the walking track, so that the charging host can run back and forth between the mounting platform and the charging base station; a dynamic plug-in module 301 that docks with the static plug-in module on the charging base station to form an electrical connection, and draws AC power from the grid side of the charging base station to power the charging host; at the same time, it provides the charging base station with power converted by the charging host, which is used to charge the vehicle via the charging cable and gun. As a preferred example, the dynamic plug-in module and the static plug-in module can adopt a pin structure, in which some pins are connected to signal lines. Therefore, when the dynamic plug-in module and the static plug-in module are docked and connected to each other, the multiple signal lines of the charging gun are connected to the charging host, so that various states of the new energy vehicle can be read and fed back, for example.

[0063] In addition, the charging host includes core AC / DC conversion modules, billing modules, communication modules, safety switches and other modules.

[0064] In summary, the scheduling of aerial rails can provide power to multiple parking spaces in an orderly manner in a queuing manner. When the number of charging hosts does not match the existing charging demand, the hanging rail charging hosts can be flexibly and conveniently increased or decreased to meet the charging demand, thereby achieving a dynamic balance between the charging operator's revenue, charging demand, and cost reduction.

[0065] In addition, in the automobile charging equipment / system of the present invention, when the car owner places a charging request, the idle charging host can be automatically transported to the designated parking space (target parking space) to charge the car. After being fully charged, the charging host can autonomously leave the current parking space to provide services to other car owners, thereby solving the parking space occupation problem.

[0066] At the same time, through the full parking lot coverage of the aerial rail, it can be possible to park gasoline and electric vehicles together in the parking lot at a controllable cost. As new energy vehicles gradually replace fuel vehicles, charging hosts can be added flexibly and conveniently to meet the needs of more car owners without the need for additional infrastructure investment.

[0067] In order to better understand the operation process of the automobile charging system and the automobile charging device of the present invention, the control method thereof is described in detail below.

[0068] [Charging Control Method of the Automobile Charging System / Automobile Charging Device of the Present Invention]

[0069] During the charging preparation phase, a vehicle user (hereinafter referred to as the user) parks their vehicle in a parking space (target parking space) next to any available charging base station (target charging base station), removes the charging gun 407 from the charging terminal 5, and inserts it into the vehicle's charging port. Once the charging gun is locked with the vehicle's charging port and ready for charging, the user operates the control program on the user terminal to issue a charging request to the target charging base station.

[0070] The user terminal includes but is not limited to a vehicle terminal, a mobile terminal, etc. The charging control program can be an independent mobile terminal app, a mobile terminal mini-program, etc. installed on the user terminal. The charging request at least includes the identification information of the target charging base station corresponding to the target parking space where the vehicle to be charged is parked.

[0071] The vehicle charging system of the present invention can receive the charging request through a server, or directly through the vehicle charging device of the present invention (such as the host mounting platform or the idle charging base station corresponding to the target parking space). The following description uses the case where the charging request is received by the server as an example.

[0072] After receiving a charging request, the server identifies and locks onto an idle charging host near the target charging base station based on the identification information of the target charging base station included in the charging request. It then dispatches a nearby idle charging host mounting platform to transport the idle charging host to the target charging base station to perform the charging task. After charging is completed, the charging host mounting platform returns to its initial state and begins processing the next round of charging instructions. Obviously, the functions of dispatching charging host mounting platforms and sending charging instructions are not limited to being performed by the server and can also be performed by any one of the charging base station, charging host, or charging host mounting platform, or a combination of more than two.

[0073] Below, refer to Figures 7 to 9 The charging control method of the vehicle charging device / system of the present invention is described in detail. Specifically, the charging control method of the present invention includes the following processing steps. When the vehicle charging system of the present invention receives a charging request ( Figure 9After S901 and S902), a charging instruction is sent to the idle charging host mounting platform to carry the idle charging host to the target charging base station to perform the charging task, thereby starting the following pile-taking process (including Figure 7 Steps S710 to S750 in FIG.

[0074] First, the idle charging host mounting platform receives a charging instruction to transport the idle charging host to a target charging base station to perform a charging task (charging instruction receiving step S710 ).

[0075] Then, the charging host mounting platform that receives the charging instruction performs a pile search process (pile search step S720 ), that is, the charging host mounting platform 2 that receives the charging instruction runs to the idle charging host 3 and mounts the charging host 3 .

[0076] Specifically, the pile search process in step S720 includes the following sub-processes: Figure 8 First, the charging host mounts the platform to leave the current charging base station (S810). The leaving step S810 specifically includes Figure 9 The following sub-steps S903 to S904 are as follows: the positioning module 203 of the charging host mounting platform 2 retracts (releasing the parking fixed beam 403) to end the locked state with the parking fixed beam 403 of the charging base station 4 (S903); the travel module 201 of the charging host mounting platform 2 drives the charging host mounting platform 2 along the travel guide rail 101 to the charging base station 4 where the nearest idle charging host 3 is located (S904). The base station position identifier 207 can calibrate the relative position of the charging host mounting platform 2 and the charging base station 4.

[0077] Next, step S820 is entered, and the charging host mounting platform performs parking processing for the charging base station where the idle charging host is located. Specifically, the parking processing includes Figure 9 In step S905, the charging host mounting platform 2 opens its positioning module 203 so that it grips the parking beam 403, thereby locking it with the parking beam 403 of the charging base station 4. In this locked state, the communication and power supply module 202 above the positioning module 203 is docked with the communication and power supply module 404 on the parking beam 403, allowing the charging base station 4 to supply power to the charging host mounting platform 2 and communicate with each other.

[0078] Then, step S830 is entered, and the charging host mounting platform performs the mounting process of mounting the charging host. Specifically, the mounting process in step S830 includes the following sub-steps S906 to S914. First, the push-and-receive module 205 pushes toward the charging base station 4 (S906). The proximity sensor 209 of the charging host mounting platform 2 senses the distance between the push-and-receive module 205 and the charging host 3 (S907), and determines whether it reaches the predetermined position (S908). If the predetermined position is reached, the limit assembly 204 opens to lock the charging host 3 and the push-and-receive module 205 (S909), and the push-and-receive module 205 carries the charging host 3 through the walking module 302 from the locking track 402 to the walking track 206 side (S910).

[0079] The proximity sensor 209 senses the position of the push-and-retract module 205 ( S911 ) and determines whether the push-and-retract module 205 has reached the predetermined position ( S912 ). After determining that the charging host 3 has been received at the predetermined position, the stopper assembly 204 is released ( S913 ). The positioning assembly 303 of the charging host 3 locks with the stopper assembly 204 of the charging host mounting platform 2, locking the charging host 3 and the charging host mounting platform 2 ( S914 ). This concludes the pile search process ( S720 ).

[0080] Next, the process proceeds to step S730, where the charging host mounting platform, which carries the charging host, executes a charging host transport process to transport the charging host to the target charging base station according to the received charging instruction. The charging host transport process specifically includes sub-steps S915 to S917.

[0081] First, the positioning module 203 of the charging host mounting platform 2 is released, releasing the locked state with the parking fixed beam 403 (S915). Then, the charging host mounting platform 2, carrying the charging host 3, moves along the running rails 101 to the target charging base station 4 (S916). The base station position identifier 207 calibrates the relative position of the charging host mounting platform 2 and the charging base station 4. The positioning module 203 then grips the parking fixed beam, locking it with the parking fixed beam 403 of the target charging base station (S917).

[0082] Next, the unloading and host docking step S740 is entered, where the charging host mounting platform 2 unloads the charging host 3 and docks the charging host with the target charging base station. Specifically, the unloading and host docking process in step S740 includes the following sub-steps S918 to S927.

[0083] First, the limiting assembly 204 of the charging host mounting platform 2 opens (S918), locking the charging host 3 with the push-and-receive module 205 (S919). Then, the push-and-receive module 205 pushes the charging host 3 toward the target charging base station 4 (S920), causing the charging host 3 to move along the running track 206 of the charging host mounting platform 2 to the locking track 402 of the charging base station 4. The proximity sensor 209 senses the position of the push-and-receive module 205 (S921) and determines whether it has reached the predetermined position (S922). If the limiting assembly 204 is released (S923), the positioning assembly 303 of the charging host 3 is locked with the locking track 402 (S924), and the dynamic plug-in module 301 of the charging host 3 is electrically connected to the static plug-in module 401 of the charging base station 4 (S925). In this electrically connected state, the charging host 3 can draw AC power from the charging base station 4 to power the charging host, and can also supply DC power converted by the charging host 3 to the charging base station 4, so that the charging host 3 can charge the vehicle through the charging gun connected to the charging base station 4. Thus, the charging host 3 completes the charging protocol handshake with the vehicle through the charging gun 407 (S927).

[0084] As a result, the charging host 3 completes the charging protocol handshake with the vehicle through the charging gun 407 ( S927 ).

[0085] After step S740, the process proceeds to initialization step S750 and charging and billing step S760. In step S750, the charging host mounting platform is initialized to an idle state. Initialization step S750 further includes steps S928 to S932. Specifically, the push-and-receive module 205 is retracted toward the charging host mounting platform 2 (S928), the position of the push-and-receive module 205 is sensed (S929), and a determination is made as to whether the predetermined position has been reached (S930). If the predetermined position has been reached, the push-and-receive module 205 returns to its initial state (S931), and the state of the charging host mounting platform 2 is changed to an idle state (S932), thereby completing the charging pile removal process.

[0086] In the charging and billing step S760, the charging host 3 starts to supply power to the vehicle and starts billing (S927), and the charging control process ends here.

[0087] In summary, the technical solution of the present invention effectively solves the problem of parking space timeout during energy replenishment for new energy vehicles, improves parking space utilization, and enhances the user's charging experience.

[0088] Although the present invention has been described above with reference to exemplary embodiments, the above embodiments are intended only to illustrate the technical concepts and features of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent variations or modifications made based on the spirit and essence of the present invention shall be included within the scope of protection of the present invention.
