Description

Technical Field

[0001] The present application relates to the technical field of charging piles, and particularly to a mobile charging pile for new energy vehicles and a control method therefor. Background Art

[0002] With the increasing emphasis on environmental issues, the development and popularization of clean energy have also been regarded as one of the important strategies for the sustainable development path by countries around the world. Among them, with the continuous development of new energy vehicles, various supporting facilities for new energy vehicles are also undergoing frequent iterative updates. In particular, the charging equipment for supplementing electric energy for new energy vehicles, including various charging guns, charging piles, charging stations, vehicle-mounted batteries, and various charging schemes with different strategies.

[0003] The charging pile for new energy vehicles is used to supplement the driving electric energy for new energy vehicles, so as to provide traveling electric energy, lighting electric energy, multimedia electric energy, etc. for new energy vehicles. Therefore, the charging pile for new energy vehicles and new energy vehicles are interdependent and inseparable.

[0004] Generally speaking, the charging piles for new energy vehicles are configured at fixed positions around the new energy vehicle parking spaces in the charging station. That is to say, the vehicle owner can only supplement the electric energy for the new energy vehicle by parking the new energy vehicle in the parking space with an idle charging pile. Once the new energy vehicle that has been charged does not leave this parking space, then the charging pile in this parking space will not be able to supplement the electric energy for the next new energy vehicle, greatly reducing the use efficiency of the charging pile, also reducing the charging experience of new energy vehicle users, and at the same time prolonging the time period for the recovery of the investment funds of the charging station. Summary of the Invention

[0005] In order to improve the use efficiency of the charging pile for new energy vehicles, the present application provides a mobile charging pile for new energy vehicles and a control method therefor.

[0006] In a first aspect, a mobile charging pile for new energy vehicles provided by the present application adopts the following technical solution:

[0007] A mobile charging pile for new energy vehicles includes a main rail, a first secondary rail, a second secondary rail, and a pile body;

[0008] The pile body can move along the main rail, the first secondary rail, and the second secondary rail;

[0009] A notch is provided on the main rail, the first secondary rail and the second secondary rail are arranged at the notch, the first secondary rail and the second secondary rail can fill the notch, and the first secondary rail and the second secondary rail move synchronously and in the same direction.

[0010] Through the above technical solution, after the vehicle owner parks the new energy vehicle in the parking space corresponding to the main rail gap, according to the charging needs of the vehicle itself, the vehicle owner sends a message to summon the charging pile through scanning the code on the mobile terminal or other means. The system of this charging pile device integrates the charging needs of the vehicle owner and various information of the charging station, generates a charging summons message for the pile body, and obtains the gap number where the vehicle with charging needs is located according to the charging summons message.

[0011] If there is no pile body in the parking space, the optimal pile body is matched for the vehicle with charging needs and the optimal pile body is driven to move along the main rail towards the vehicle. At this time, the main rail is in a closed-loop state, that is, the secondary rail two of the gap where the vehicle with charging needs is located fills the corresponding main rail gap.

[0012] After the optimal pile body travels to the secondary rail two of the gap where the vehicle with charging needs is located, it stops advancing. The system controls the secondary rail one and the secondary rail two to move synchronously in the same direction. On the one hand, the secondary rail two drives the optimal pile body to move forward and approach the vehicle, facilitating charging. On the other hand, the secondary rail one fills the corresponding main rail gap, closing the main rail again and facilitating the provision of a moving path for other pile bodies.

[0013] After the vehicle finishes charging, if the vehicle that has finished charging has not left the parking space, when the next vehicle with charging needs sends a charging summons message, at this time, not only can the pile body in the main rail be summoned for charging, but also the pile body that has finished charging and is located at the gap can be summoned, effectively improving the utilization efficiency of the charging pile, enhancing the charging experience of new energy vehicle users, and at the same time shortening the time cycle for the recovery of the investment funds of the charging station.

[0014] In a preferred example of the present application, it can be further configured as: further including a support frame, the support frame is arranged at the gap, the secondary rail one and the secondary rail two are both slidably installed on the support frame, a charging interface is arranged on the support frame, a charging plug is arranged on the pile body, and when the charging plug is inserted into the charging interface, it can provide electric energy for the pile body.

[0015] Through the above technical solution, during the process of the secondary rail two driving the pile body to move along the support frame, not only can the main rail be closed again and the pile body approach, but also the docking of the charging plug and the charging interface is completed, enabling the charging gun on the pile body to obtain power supply, so that the vehicle can be charged.

[0016] That is to say, when the charging interface and the charging plug are not docked, the charging gun of the pile body is not charged, which also improves the safety during the use of the charging gun.

[0017] In a preferred example, the present application can be further configured as follows: a first baffle is installed on the first secondary rail, a second baffle is installed on the second secondary rail, the second secondary rail is located between the first secondary rail and the charging interface, the first baffle is in abutting cooperation with the side wall of the main rail away from the charging interface, and the second baffle is in abutting cooperation with the side wall of the main rail close to the charging interface.

[0018] Through the above technical solution, during the process of the second secondary rail driving the pile body to move along the support frame, the first secondary rail and the first baffle also move synchronously and in the same direction. After the charging plug and the charging interface are docked, the first secondary rail also merges into the gap of the main rail. Under the blocking effect of the first baffle, the possibility of the main rail failing to form a closed loop due to excessive displacement of the first secondary rail and the second secondary rail is reduced, thereby improving the smoothness of the subsequent movement of the pile body.

[0019] In a preferred example, the present application can be further configured as follows: a first charging module and a second charging module are arranged in the pile body. When the charging plug is inserted into the charging interface, it can provide electric energy to the first charging module and the second charging module. The first charging module is used to provide electric energy for the movement of the pile body, and the second charging module is used to provide electric energy for the vehicle.

[0020] Through the above technical solution, after the charging plug and the charging interface are docked, the first charging module can obtain electric energy from the power grid to replenish the electric energy of the first charging module, thereby extending the distance that the pile body can travel. The second charging module can also obtain electric energy from the power grid and supply it to the vehicle.

[0021] In a preferred example, the present application can be further configured as follows: a connection module is further arranged in the pile body, and the connection module is used to control the on-off of the electric energy between the first charging module and the second charging module.

[0022] Through the above technical solution, when a power outage occurs at the charging station where the vehicle is located, at this time, the second charging module will not be able to obtain electric energy from the power grid. At this time, since the pile body itself has the first charging module, it can provide operating electric energy for the pile body. After the pile body detects that the charging of the second charging module is interrupted due to a power outage, it controls the connection module to start, realizing the conduction between the first charging module and the second charging module. At this time, the second charging module can obtain electric energy from the first charging module, that is, the second charging module acts as a charging medium, and on the premise of maintaining its own movement, it supplies the electric energy of the first charging module to the vehicle, thereby improving the vehicle's cruising range and further enhancing the user's experience.

[0023] In the second aspect, based on the above-mentioned mobile charging pile for new energy vehicles, the present application also provides a control method for a mobile charging pile for new energy vehicles, adopting the following technical solution:

[0024] A control method for a mobile charging pile for a new energy vehicle, the method comprising:

[0025] Number each notch in the main rail;

[0026] Obtain the charging call information of the pile body;

[0027] Based on the charging call information, obtain the notch number where the vehicle with charging demand is located;

[0028] If there is no pile body in the parking space corresponding to the notch number, match the optimal pile body for the vehicle corresponding to the notch number;

[0029] Generate a call instruction for the optimal pile body.

[0030] Through the above technical solution, a number of notches are provided in each main rail, and the distribution density of the number of notches on a straight line or on a curve with the same radius of curvature is the same or relatively close. Each notch is assigned a different number to distinguish the notch position.

[0031] After the system obtains the charging call information, it obtains the notch number where the vehicle with charging demand is located, so as to match the pile body for the vehicle. If there is no pile body in the parking space corresponding to the notch, combined with information such as the distance and remaining power of each pile body, the optimal pile body is matched for the vehicle, and a call information for the optimal pile body is generated, so that the optimal pile body travels to the notch position where the vehicle is located.

[0032] After the pile body travels into the secondary rail two at the notch position where the vehicle is located, the secondary rail two drives the pile body to move in the direction close to the vehicle, so that the vehicle owner can take the charging pile from the optimal pile body to charge the vehicle.

[0033] In a preferred example of the present application, it can be further configured that matching the optimal pile body for the vehicle corresponding to the notch number includes:

[0034] Obtain the remaining power information of each idle pile body and the preset travel energy consumption speed of the pile body;

[0035] Based on the remaining power information of each idle pile body and the travel energy consumption speed, calculate multiple estimated travel durations;

[0036] Obtain the track distance one between the position where the notch number is located and each pile body;

[0037] Based on the multiple track distances one and the preset travel speed of the pile body, calculate multiple actual required travel durations;

[0038] Compare the estimated travel duration and the actual required travel duration of each pile body. If the estimated travel duration is greater than the actual required travel duration, add the pile body to the matching sample;

[0039] Obtain the track distance two between each pile body in the matching sample and the position where the notch number is located, and match the optimal pile body according to the multiple track distances two.

[0040] Through the above technical solution, according to the remaining power and the traveling energy consumption speed of each idle pile body (i.e., the pile body in the non-charging state in a timely manner), the duration that the pile body can still move forward can be calculated, that is, the expected traveling duration.

[0041] Then, according to the track distance one of each idle pile body (the track distance one refers to the distance that the pile body moves along the track, not the straight-line distance) and the traveling speed, the actual required traveling duration of the pile body can be calculated, that is, the duration required for the idle pile body to travel to the notch position.

[0042] Next, compare the expected traveling duration and the actual required traveling duration of each pile body. If the expected traveling duration is greater than the actual required traveling duration, it means that the current remaining electric energy of the pile body is sufficient to support it to travel to the position where the notch is located, and thus it can provide charging service for the vehicle. If the expected traveling duration is less than or equal to the actual required traveling duration, it means that the current remaining electric energy of the pile body is not sufficient to support it to travel to the position where the notch is located, and thus it is difficult to provide charging service for the vehicle.

[0043] Include the pile bodies with the expected traveling duration greater than the actual required traveling duration in the matching sample, and select the optimal pile body according to the track distance two of the pile bodies in the matching sample (the track distance one refers to the distance that the pile body moves along the track, not the straight-line distance, and the track distance one and the track distance two are only used for distinction) to perform charging for the vehicle.

[0044] This technical solution pre-evaluates the electric energy of the pile body to obtain whether the pile body can move to the vicinity of the vehicle with charging requirements, thereby reducing the possibility of the vehicle owner making the pile body calling action twice or multiple times, and further improving the user experience.

[0045] In a preferred example, this application can be further configured that the matching the optimal pile body according to the multiple track distances two includes:

[0046] Sort the pile bodies in the matching sample according to the multiple track distances two;

[0047] Set the pile body with the smallest track distance two as the optimal pile body.

[0048] Through the above technical solution, according to the track distance two of multiple pile bodies in the matching sample, the multiple pile bodies in the matching sample are sorted, and the pile body with the smallest track distance two is set as the optimal pile body. Since the preset traveling speed of the pile body is constant, the smaller the distance, the shorter the time required for the pile body to travel to the notched vehicle, and the vehicle owner can replenish the electric energy of the vehicle in the shortest time, thus further improving the user experience.

[0049] In a preferred example of the present application, it can be further configured that after setting the pile body with the smallest track distance two as the optimal pile body, it further includes:

[0050] If there are two pile bodies with the smallest track distance two, and the two pile bodies are respectively on both sides of the positions corresponding to the notch numbers, then the pile body without idle notches on the moving path is set as the optimal pile body.

[0051] Since the main track is usually a closed-loop track, there are several pile bodies on both sides of each notch. That is to say, there may be two pile bodies with the same track distance two, that is, the two pile bodies are respectively on both sides of the notch and at the same distance from the position where the notch is located.

[0052] Through the above technical solution, if there are two pile bodies with the smallest track distance two, and the two pile bodies are respectively on both sides of the positions corresponding to the notch numbers, then the pile body without idle notches on the moving path is set as the optimal pile body. The reason for setting the pile body without idle notches on the moving path as the optimal pile body is that there is a possibility that a vehicle will drive into the idle notch at any time, that is, there is a possibility that another vehicle owner will summon the next pile body before the movement of the previous optimal pile body is completed. In this way, the two summoned pile bodies move simultaneously in the main track and may interfere with each other.

[0053] Therefore, setting the pile body without idle notches on the moving path as the optimal pile body can reduce the possibility of mutual interference when multiple pile bodies move simultaneously, which is not only beneficial to improving the user experience but also can reduce the power consumption caused by the pile body's return movement.

[0054] In a preferred example of the present application, it can be further configured that if the expected travel duration of each pile body is less than or equal to the corresponding actual required travel duration, then the pile body with the smallest track distance one is set as the optimal pile body;

[0055] Drive the optimal pile body to travel into the nearest notch in the forward direction and charge;

[0056] When the remaining power in the optimal pile body reaches enough to travel to the position corresponding to the notch number, stop charging and travel to the position corresponding to the notch number.

[0057] With the above technical solution, if the expected travel time of each pile body is less than or equal to the corresponding actual required travel time, the pile body with the smallest track distance is set as the optimal pile body, and the optimal pile body is driven into the nearest idle gap in the forward direction to charge the optimal pile body, thereby extending the moving distance of the pile body. When the remaining power in the optimal pile body reaches enough to travel to the position corresponding to the gap number, the charging ends, and the pile body travels to the position corresponding to the gap number to charge the vehicle.

[0058] In the case where the electric energy of all idle pile bodies is insufficient, the optimal pile body selected by this solution is the closest to the corresponding vehicle, and at the same time, it travels to the nearest gap in the traveling direction for charging, so as to be able to replenish electric energy in the shortest time and charge the vehicle.

[0059] In summary, the present application includes the following beneficial technical effects:

[0060] 1. If the vehicle that has completed charging has not left the parking space, after the next vehicle with a charging requirement sends a charging call message, not only can it call the pile body in the main track for charging, but also can call the pile body that has completed charging and is located at the gap, effectively improving the utilization efficiency of the charging pile, enhancing the charging experience of new energy vehicle users, and at the same time shortening the time cycle for the investment funds of the charging station to return.

[0061] 2. After the pile body moves to the secondary track two at the gap, the secondary track two moves in the direction close to the vehicle. On the one hand, the secondary track two drives the optimal pile body to move forward and approach the vehicle, facilitating charging; on the other hand, it completes the docking of the charging plug and the charging interface and completes the conduction of the circuit; on the third hand, it enables the secondary track one to fill the corresponding main track gap and closes the main track again, facilitating the provision of a moving path for other pile bodies.

[0062] 3. Through the connection module set in the pile body, the on-off of electric energy between the charging module one and the charging module two is realized. When a power outage occurs at the charging station where the vehicle is located, the connection module is started to realize the conduction of the charging module one and the charging module two, and the electric energy of the charging module one is supplied to the vehicle, thereby improving the vehicle's cruising range.

[0073] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 8 diagrams.

[0074] An embodiment of the present application discloses a mobile charging pile for new energy vehicles.

[0075] Referring to the attached Figure 1 diagrams, a mobile charging pile for new energy vehicles includes a main rail 1, a secondary rail one 11, a secondary rail two 12, a pile body 2, and a support frame 3.

[0076] Referring to the attached Figure 1 and the attached Figure 2 and the attached Figure 3 diagrams, wherein, the main rail 1 is suspended and installed above the new energy vehicle parking spaces in the charging station. According to the distribution of the new energy vehicle parking spaces, the main rail 1 can be set into different shapes, such as a ring, a circle, a rounded rectangle, etc. Only one shape of the main rail 1 is shown in the attached diagrams. The main rail 1, the secondary rail one 11, and the secondary rail two 12 have the same longitudinal section. Grooves with a T-shaped longitudinal section are opened in the main rail 1, the secondary rail one 11, and the secondary rail two 12 for the pile body 2 to move. The pile body 2 can move along the main rail 1, the secondary rail one 11, and the secondary rail two 12.

[0077] Referring to the attached Figure 1 and the attached Figure 2 and the attached Figure 3As shown in the figure, a plurality of notches 13 are formed in the main rail 1. For the sake of simplicity of the accompanying drawings, only one notch 13 is shown in the relevant drawings. At each notch 13, a first auxiliary rail 11, a second auxiliary rail 12 and a support frame 3 are provided. The support frame 3 is suspended above the new energy vehicle space in the charging station and is also above the main rail 1. Both the first auxiliary rail 11 and the second auxiliary rail 12 are slidably mounted on the support frame 3. The first auxiliary rail 11 and the second auxiliary rail 12 can fill the notch 13. The lengths of the first auxiliary rail 11 and the second auxiliary rail 12 are the same as the length of the notch 13. The first auxiliary rail 11 and the second auxiliary rail 12 move synchronously and in the same direction, and the sliding directions of the first auxiliary rail 11 and the second auxiliary rail 12 are perpendicular to the length direction of the main rail 1.

[0078] Referring to the attached Figure 1 、attached Figure 3 and attached Figure 4 As shown, a charging interface 31 is provided on the support frame 3, and a charging plug 21 is provided on the pile body 2. When the charging plug 21 is inserted into the charging interface 31, it can provide electric energy for the pile body 2.

[0079] After the vehicle owner parks the new energy vehicle in the parking space corresponding to the notch 13 of the main rail 1, according to the vehicle charging demand, the vehicle owner sends a message to summon the charging pile by scanning the code on the mobile terminal or other means, controls the system of this charging pile device, integrates the vehicle owner's charging demand and various information of the charging station, generates a charging summon message for the pile body 2, and obtains the notch 13 number where the vehicle with the charging demand is located according to the charging summon message.

[0080] If there is no pile body 2 in the parking space, the optimal pile body 2 in the idle state is matched for the vehicle, and the optimal pile body 2 is driven to move along the main rail 1 towards the vehicle. Before the pile body 2 enters the notch 13, the notch 13 in the main rail 1 is closed by the second auxiliary rail 12. Therefore, the matched optimal pile body 2 moves along the main rail 1 to the second auxiliary rail 12 at the notch 13.

[0081] After the optimal pile body 2 moves to the second auxiliary rail 12 at the notch 13, it stops moving forward and maintains the optimal pile body 2 in the second auxiliary rail 12. Then, the first auxiliary rail 11 and the second auxiliary rail 12 are controlled to move along the support frame 3 towards the vehicle. On the one hand, it is convenient for the vehicle owner to take the charging gun from the pile body 2; on the other hand, the first auxiliary rail 11 fills the corresponding notch 13 of the main rail 1, closes the main rail 1 again, and is convenient for providing a moving path for other pile bodies 2; on the other hand, the charging plug 21 on the pile body 2 is inserted into the charging interface 31 to complete the conduction of the circuit.

[0082] After the vehicle finishes charging, if the vehicle that has completed charging does not leave the parking space, when the next vehicle with a charging demand sends a charging summons message, at this time, not only can the pile body 2 in the main rail 1 be summoned for charging, but also the pile body 2 located at the notch 13 and that has completed charging can be summoned, effectively improving the utilization efficiency of the charging pile, enhancing the charging experience of new energy vehicle users, and at the same time shortening the time cycle for the investment funds of the charging station to be recovered.

[0083] In addition, in the above technical solution, the wire or conductive copper bar is arranged in the support frame 3 outside the main rail 1, rather than in the track of the main rail 1, which effectively reduces the probability of safety accidents and is conducive to strengthening the protection of the charging pile-related equipment.

[0084] Refer to the attached Figure 3 and the attached Figure 4 As shown, a first baffle 111 is installed on the first secondary rail 11, a second baffle 121 is installed on the second secondary rail 12, the second secondary rail 12 is located between the first secondary rail 11 and the charging interface 31, the first baffle 111 is in abutting fit with the side wall of the main rail 1 away from the charging interface 31, and the second baffle 121 is in abutting fit with the side wall of the main rail 1 close to the charging interface 31.

[0085] During the process of the second secondary rail 12 driving the pile body 2 to move along the support frame 3, the first secondary rail 11 and the first baffle 111 also move synchronously and in the same direction. After the charging plug 21 and the charging interface 31 are docked, the first secondary rail 11 also merges into the notch 13 of the main rail 1 accordingly. Under the blocking action of the first baffle 111, the possibility of the main rail 1 failing to form a closed loop due to excessive displacement of the first secondary rail 11 and the second secondary rail 12 is reduced, thereby improving the smoothness of the subsequent movement of the pile body 2.

[0086] The function of the second baffle 121 is the same as that of the first baffle 111, and will not be elaborated here.

[0087] A first charging module and a second charging module are provided in the pile body 2. In the state where the charging plug 21 is inserted into the charging interface 31, electric energy can be provided to the first charging module and the second charging module. The first charging module is used to provide electric energy for the movement of the pile body 2, and the second charging module is used to provide electric energy for the vehicle. After the charging plug 21 and the charging interface 31 are docked, the first charging module can obtain electric energy from the power grid to replenish the electric energy of the first charging module, thereby extending the distance that the pile body 2 can travel. The second charging module can also obtain electric energy from the power grid and supply it to the vehicle.

[0088] A connection module is also provided inside the pile body 2. The connection module is used to control the on-off of the electric energy between the first charging module and the second charging module. When a power outage occurs at the charging station where the vehicle is located, at this time, the second charging module will not be able to obtain electric energy from the power grid. At this time, since the pile body 2 itself has the first charging module, it can provide operating electric energy for the pile body 2. After the pile body 2 detects that the charging of the second charging module is interrupted due to a power outage, it controls the connection module to start, realizing the conduction between the first charging module and the second charging module. At this time, the second charging module can obtain electric energy from the first charging module, that is, the second charging module acts as a charging medium. On the premise of maintaining its own movement, it supplies the electric energy of the first charging module to the vehicle, thereby improving the vehicle's cruising range and further enhancing the user's experience.

[0089] Refer to the attached Figure 5 As shown, based on the above-mentioned mobile charging pile for new energy vehicles, the present application also provides a control method for the mobile charging pile for new energy vehicles.

[0090] A control method for a mobile charging pile for new energy vehicles, the method comprising the following steps:

[0091] S101. Number each notch 13 in the main rail 1.

[0092] In implementation, a number of notches 13 are provided in the main rail 1. The distribution density of the number of notches 13 on a straight line or on a curve with the same radius of curvature is the same or relatively close. Each notch 13 is assigned a different number to distinguish the position of the notch 13.

[0093] S102. Obtain the charging call information of the pile body 2.

[0094] In implementation, the system also timely obtains the charging call information about the pile body 2. The charging call information includes the remaining battery power information of the vehicle, the charging type (such as fast charging or normal charging), the number of the notch 13 corresponding to the vehicle's location, and so on.

[0095] S103. Based on the charging call information, obtain the number of the notch 13 where the vehicle with a charging demand is located.

[0096] In implementation, obtaining the number of the notch 13 included in the charging call information not only facilitates identifying the location of the vehicle with a charging demand, but also facilitates determining the distance for the subsequent matching of the optimal pile body 2.

[0097] S104. If there is no pile body 2 in the parking space corresponding to the notch 13 number, match the optimal pile body 2 for the vehicle corresponding to the notch 13 number.

[0098] In implementation, if there is a pile body 2 in the parking space corresponding to the notch 13 number, the pile body 2 can be directly used for charging. If there is no pile body 2 in the parking space corresponding to the notch 13 number, the optimal pile body 2 is matched for the vehicle corresponding to the notch 13 number. The matching principle and process of the specific pile body 2 will be elaborated in detail later.

[0099] S105. Generate a summons instruction for the optimal pile body 2.

[0100] In implementation, after the optimal pile body 2 is matched, a summons instruction for the optimal pile body 2 is generated to summon the matched optimal pile body 2 to travel to the location of the vehicle.

[0101] Refer to the appendix Figure 6 As shown, matching the optimal pile body 2 for the vehicle corresponding to the notch 13 number may include the following processing steps:

[0102] S201. Obtain the remaining power information of each idle pile body 2 and the preset energy consumption speed of the pile body 2 during travel.

[0103] In implementation, the remaining power information can be directly obtained from the battery in the pile body 2. Since the average travel speed of the pile body 2 is fixed (the average speed mentioned here includes the starting acceleration stage, the uniform travel stage, and the deceleration stage of the pile body 2), the energy consumption speed of the pile body 2 during travel (that is, the speed at which the pile body 2 consumes electric energy per unit distance) is also fixed.

[0104] S202. Calculate multiple estimated travel durations based on the remaining power information and the energy consumption speed of each idle pile body 2 during travel.

[0105] In implementation, according to the remaining power and the energy consumption speed of each idle pile body 2 (that is, the pile body 2 in a non-charging state), the duration that the pile body 2 can still travel forward can be calculated, which is the estimated travel duration, that is, the remaining power divided by the energy consumption speed during travel to obtain the estimated travel duration.

[0106] S203. Obtain the track distance one between the location of the notch 13 number and each pile body 2.

[0107] In implementation, it should be noted that the track distance one mentioned here refers to the distance that the pile body 2 moves along the track in the direction of the notch 13 position, not the straight-line distance.

[0108] S204. Calculate multiple actual required travel durations based on the multiple track distances one and the preset travel speed of the pile body 2.

[0109] In implementation, according to the track distance one and the traveling speed of each idle pile body 2, the actual required traveling duration of the pile body 2 can be calculated, that is, the duration required for the idle pile body 2 to travel to the position of the gap 13, which is obtained by dividing the track distance one by the traveling speed to get the actual required traveling duration.

[0110] S205. Compare the predicted traveling duration and the actual required traveling duration of each pile body 2. If the predicted traveling duration is greater than the actual required traveling duration, add the pile body 2 to the matching sample.

[0111] In implementation, if the predicted traveling duration is greater than the actual required traveling duration, it means that the current remaining electric energy of the pile body 2 is sufficient to support it to travel to the position where the gap 13 is located, and thus it can provide charging service for the vehicle. At this time, the pile body 2 with the predicted traveling duration greater than the actual required traveling duration is included in the matching sample of the optimal pile body 2 for further screening.

[0112] Similarly, if the predicted traveling duration is less than or equal to the actual required traveling duration, it means that the current remaining electric energy of the pile body 2 is not sufficient to support it to travel to the position where the gap 13 is located, and thus it is difficult to provide charging service for the vehicle.

[0113] S206. Obtain the track distance two between each pile body 2 in the matching sample and the position where the number of the gap 13 is located, and match the optimal pile body 2 according to the multiple track distances two.

[0114] In implementation, the specific steps for matching the optimal pile body 2 in the matching sample are described later.

[0115] Refer to the appendix Figure 7 As shown, matching the optimal pile body 2 according to the multiple track distances two includes the following processing steps:

[0116] S301. Sort the pile bodies 2 in the matching sample according to the multiple track distances two.

[0117] S302. Set the pile body 2 with the smallest track distance two as the optimal pile body 2.

[0118] In implementation, since the preset traveling speed of the pile body 2 is constant, the smaller the distance, the shorter the time required for the pile body 2 to travel to the vehicle at the gap 13, and the vehicle owner can replenish the electric energy of the vehicle in the shortest time, thereby further improving the user experience.

[0119] After setting the pile body 2 with the smallest track distance two as the optimal pile body 2, the following processing steps are further included:

[0120] If there are two pile bodies 2 with the smallest track distance two, and the two pile bodies 2 are respectively on both sides of the position corresponding to the number of the gap 13, set the pile body 2 without an idle gap 13 on the moving path as the optimal pile body 2.

[0121] Since the main track 1 is usually a closed-loop track (considering the case where the notch 13 forms a closed loop), there are several pile bodies 2 on both sides of each notch 13. That is to say, there may be two pile bodies 2 with a track distance of two, namely, the two pile bodies 2 are respectively on both sides of the notch 13 and at the same distance from the position where the notch 13 is located.

[0122] Through the above processing method, if there are two pile bodies 2 with the smallest track distance of two, and the two pile bodies 2 are respectively on both sides of the positions corresponding to the notch 13 numbers, then the pile body 2 without idle notch 13 on the moving path is set as the optimal pile body 2. The reason for setting the pile body 2 without idle notch 13 on the moving path as the optimal pile body 2 is that there is a possibility that a vehicle will drive into the idle notch 13 at any time. That is, there is a possibility that another vehicle owner summons the next pile body 2 before the movement of the previous optimal pile body 2 is completed. In this way, the two summoned pile bodies 2 move simultaneously in the main track 1, and mutual interference may occur.

[0123] Therefore, setting the pile body 2 without idle notch 13 on the moving path as the optimal pile body 2 can reduce the possibility of mutual interference when multiple pile bodies 2 move simultaneously, which is not only beneficial to improving the user experience but also can reduce the power consumption caused by the pile body 2's return movement.

[0124] Refer to the appendix Figure 8 As shown, after comparing the estimated travel time and the actual required travel time of each pile body 2, the following processing steps can also be included:

[0125] S401: If the estimated travel time of each pile body 2 is less than or equal to the corresponding actual required travel time, then set the pile body 2 with the smallest track distance of one as the optimal pile body 2.

[0126] In implementation, if the estimated travel time of each pile body 2 is less than or equal to the corresponding actual required travel time, it means that the current remaining power in each idle pile body 2 is not enough to support the pile body 2 to travel to the position of the notch 13 where the vehicle is located. At this time, set the pile body 2 with the smallest track distance of one as the optimal pile body 2 to find the nearest charging notch 13 position.

[0127] S402: Drive the optimal pile body 2 to travel into the nearest notch 13 in the forward direction and charge.

[0128] In implementation, the system controls the optimal pile body 2 to travel into the nearest notch 13 in the forward direction to supplement the power of the optimal pile body 2, thereby extending the moving distance of the pile body 2.

[0129] S403: When the remaining power in the optimal pile body 2 reaches enough to travel to the position corresponding to the notch 13 number, end the charging and travel to the position corresponding to the notch 13 number.

[0130] In implementation, when the remaining power in the optimal pile body 2 is sufficient to support the pile body 2 to travel to the position corresponding to the number of the notch 13, the charging of the pile body 2 is stopped, and then the pile body 2 is driven to travel to the position corresponding to the number of the notch 13, that is, the position where the charging summons information is sent, so as to charge the vehicle.

[0131] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
