Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and in particular to an orderly charging system for electric vehicles. Background Art

[0002] With the increasing number of electric vehicles, electric vehicle charging has also brought great impact on the power grid, so orderly charging has gradually become a research hotspot. For example, patent document 1 (CN115648995A) discloses a method for non-conductive orderly charging of electric vehicles, which collects the historical occupancy information of each reservable charging pile in each time period and analyzes the optimal charging coefficient, and sorts the reservable charging piles according to the size of the optimal charging coefficient YC, so that the owner can choose a suitable target charging pile for charging. Its orderly charging method does not have a matching vehicle charging device. When charging many vehicles, it completely relies on software support, which will also make the charging of electric vehicles more difficult; for example, patent document 2 (CN118544855A) discloses a smart charging pile for new energy vehicles, which is equipped with a suspended charging gun on the charging parking space, and the charging gun can dynamically adjust the charging according to the position of the car on the charging parking space. The position of the gun enables the charging gun to adapt well to the charging port of new energy vehicles. However, it can only charge a single car in a single parking space. If the car is not driven out in time after being charged, the charging gun cannot be well utilized, resulting in charging waste; finally, as disclosed in Patent Document 3 (CN114248648A), a self-service gun-pulling and car-moving charging station for electric vehicles is provided, which is provided with an electric vehicle charging position and an electric vehicle standby position, and realizes the movement of the electric vehicle from one parking space to another through a conveyor belt structure. When the electric vehicle is not moved out in time after being charged, the conveyor belt structure can be used to charge the next electric vehicle. However, this method can only charge a small number of vehicles. When there are many vehicles, it is not possible to realize orderly charging of multiple vehicles. In addition, it does not take into account how to make efficient and reasonable charging plan arrangements for multiple vehicles.

[0003] In summary, in the prior art, orderly charging of electric vehicles has been achieved by optimizing relevant parameters of charging piles. However, there is no charging system that can efficiently charge more vehicles and is matched with orderly charging, nor is there a system that can achieve intelligent charging of a charging gun on a parking space for vehicles in adjacent parking spaces by changing the shape of the charging rail. In addition, it is not considered that when a car owner is in an emergency and needs to use the car urgently during charging, the vehicle can be quickly taken. For this reason, the present invention provides a charging gun running rail whose shape can be deformed accordingly according to the charging situation, so that the vehicle in the charging parking space can be fully charged without leaving and affecting the charging. By changing the charging gun running rail from a circle to an ellipse, the charging gun can be extended into the adjacent parking space, so that the adjacent parking space is also converted into a charging parking space. Considering that the vehicle can be taken away in time during charging, three layers of vehicle taking layers are set accordingly, so that the vehicles can be diverted to prevent the vehicles from being concentrated on a certain layer and causing congestion. In addition, combined with a conveyor belt structure, an orderly charging system for electric vehicles with reasonable arrangement for charging of large quantities of vehicles can be realized. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an orderly charging system for electric vehicles, which is composed of a power grid, an orderly charging management system, a charging pile, an electric vehicle and a car owner's mobile phone APP. The orderly charging management system is communicated with the power grid, the charging pile and the car owner's mobile phone APP. The orderly charging management system generates an orderly charging control strategy based on the vehicle information of the electric vehicle, the power grid regulation information, and the charging pile operation information, controls the start and stop time of the orderly charging equipment and the output power of the charging process, and carries out orderly charging operations.

[0005] Preferably, the charging process of the orderly charging management system and the charging pile is as follows: the orderly charging management system controls the vehicle to lock and send charging parameters, and determines whether no feedback is received for more than 1s. If so, the charging pile loss status is recorded and a fault is notified for troubleshooting; if not, it is determined whether the charging status is received on time. If not, the charging pile loss status is recorded and a fault is notified for troubleshooting. If so, it is determined whether charging is completed. If charging is not completed, it returns to determine whether the charging status is received on time. If charging is completed, it determines whether there is a queued charging application. If so, it returns to the orderly charging management system to control the vehicle to lock the concurrent charging parameters, and performs log processing when determining whether charging is completed. If there is no queued charging application, it enters the sleep process.

[0006] Preferably, the connection process between the orderly charging management system and the vehicle is as follows: the electric vehicle or the owner submits a connection request and determines whether there is no response for more than 1s. If so, further determine whether the connection is more than 5 times. If so, change to manual service or replace the charging pile. Otherwise, return to the electric vehicle or the owner to submit the connection request. If the judgment is no whether there is no response for more than 1s, the electric vehicle or the owner selects the charging pile in the APP, and then continues to determine whether to charge first and then pay. If it is charging first and then paying, the vehicle is connected to the charging pile, and it is determined whether the connection is completed. After the connection is completed, the charging process is entered; if it is not charging first and then paying, it is determined whether the payment is completed, until the payment is completed, the vehicle is connected to the charging pile.

[0007] Preferably, after receiving the owner's connection request, the orderly charging management system sends the latest charging pile information to determine whether the owner's selection result has been received. After receiving it, it determines whether the charging pile is in sleep mode. If the charging pile is in sleep mode, it enters the wake-up process to wait for the vehicle to connect. If the charging pile is not in sleep mode, it waits for the vehicle to connect and determines whether the vehicle and the charging pile are correctly connected. If they are correctly connected, it enters the charging process. If they are not correctly connected, it further determines whether 10 minutes have passed. If so, it enters the sleep process. Otherwise, it returns to wait for the vehicle to connect.

[0008] Preferably, the forced disconnection process between the orderly charging management system and the vehicle is as follows: the vehicle owner sends a forced disconnection request, and determines whether the system responds.

[0009] If there is no response, contact the manual customer service or request again. If the system responds, determine whether to charge first and pay later. If so, let the owner pay. If not, determine whether the vehicle is unlocked and drive away after the vehicle is unlocked.

[0010] Preferably, the orderly charging management system receives a disconnection request and sends a notification to the charging pile to stop charging. After the charging pile is ready, the high-voltage relay is powered off to determine whether charging is done before payment. If so, it determines whether the payment is completed. After the payment is completed, it determines whether the vehicle is unlocked. If it is not done after charging, it also enters the process of determining whether the vehicle is unlocked, and then notifies the owner to update the log and enter the sleep process.

[0011] Preferably, the process of completing charging is as follows: after the orderly charging management system receives the charging completion notification, it connects to the car owner's APP and enters the step of determining whether there is no response for more than 1s. If so, it determines whether the connection exceeds 5 times. If not, it enters the step of sending the charging result status to the car owner. When it is determined that the connection exceeds 5 times, it contacts the manual customer service. If not, it continues to enter the step of connecting to the car owner's APP. After entering the step of sending the charging result status to the car owner, it determines whether the payment is made after charging. If so, it determines whether the payment is successful. After the payment is successful, it enters the step of notifying the charging pile to disconnect the cable or disconnect the locking device. If the result of determining whether the payment is made after charging is no, it also enters the step of notifying the charging pile to disconnect the cable or disconnect the locking device, and then determines whether to disconnect. After disconnection, the vehicle drives away, the charging pile goes into sleep, and finally the log is updated.

[0012] Preferably, the charging pile of the orderly charging system for electric vehicles is installed on the charging parking space, and also includes a general parking space adjacent to the charging parking space. There are several charging parking spaces and general parking spaces, and the charging parking spaces and general parking spaces are arranged adjacent to each other in an alternating manner. The charging pile includes a charging gun ring rail, and several charging guns are slidably arranged on the charging gun ring rail. The charging gun ring rail can be switched between a circle and an ellipse. When the charging ring rail is an ellipse, the charging gun can slide along the charging gun ring rail to the position of an adjacent general parking space, so that the general parking space is also turned into a charging parking space, thereby realizing orderly charging of electric vehicles in general parking spaces.

[0014] Preferably, it also includes several charging loops, each charging loop is centered on the charging parking space, and the general parking spaces on the left and right sides of the charging parking space are endpoints to form a closed loop, and a charging parking space is arranged between adjacent closed loops, and the charging loops include three layers: from top to bottom, there are a charging layer, a vehicle full layer, and an emergency vehicle retrieval layer, and the charging loops include an upper charging loop line 1 and a lower charging loop line 2, the upper charging loop line 1 includes a first vertical lane, a first horizontal lane, and a second vertical lane, the lower charging loop line 2 includes a third vertical lane, a second horizontal lane, and a fourth vertical lane, the first vertical lane, the first horizontal lane, and the second vertical lane are connected in sequence, the lower end of the first vertical lane is connected to the general parking space on the left side of the charging parking space, the lower end of the second vertical lane is connected to the general parking space on the right side of the charging parking space, and the third vertical lane is connected to the general parking space on the right side of the charging parking space.

Electric vehicles can be transported from the charging layer to the vehicle filling layer and the emergency pick-up layer through the first vertical transport position, the second vertical transport position, the third vertical transport position, the fourth vertical transport position, the fifth vertical transport position and the sixth vertical transport position.

[0015] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0016] 1. The orderly charging system of electric vehicles of the present invention includes an orderly charging management system, which can realize the orderly charging control strategy formulation, the downstream and power grid load information collection, and the charging monitoring function. The orderly charging management system is connected with the charging pile, the power grid and the owner's mobile phone APP. It can generate corresponding control commands according to the status information of the power grid, the charging pile, etc., and can also perform corresponding control according to the vehicle information sent by the owner's mobile phone APP to form corresponding log processing. In addition, it can perform charging operations on related vehicles according to whether there is a queuing charging application. It also has a forced power-off function, which can well perform the power-off operation of the charging pile when the owner needs to forcibly cut off the power. According to the corresponding charging operation, an adaptive connection protocol is also defined, so that the orderly charging of electric vehicles becomes reliable.

[0017] 2. The orderly charging system for electric vehicles of the present invention includes a charging pile which fully considers that in addition to being able to flexibly charge the car in the parking space in all directions, it also considers that the charging pile on the charging parking space can be deformed, so that the charging gun of the charging pile in the charging parking space can cover the adjacent non-charging parking space, so that by arranging a small number of charging parking spaces, it is possible to realize charging operations in non-charging parking spaces, and because the all-round coverage of the charging gun is achieved by setting a deformable guide rail structure, compared with the existing method of simply using the charging line of the charging parking space for charging in the adjacent parking space, it can make the arrangement of the charging line safer. In addition, since the charging line is suspended, it is equivalent to reinstalling a new charging parking space in the non-charging parking space, which can be safer and more convenient, and requires less investment.

[0018] 3. The charging pile of the present invention, by providing a deformable charging ring frame at the disc-shaped charging end, realizes that the charging gun ring track provided with a plurality of charging gun guide slides can be transformed between an elliptical shape and a circular shape. Through the setting of the shape change of the charging gun ring track, it can enable the charging gun guide slide equipped with the charging gun to slide along the elliptical charging gun ring track, and the long side of the ellipse extends to the half position of the adjacent parking space. With such a setting, the two elliptical charging ring tracks of the two charging parking spaces can cover the entire adjacent parking spaces, so that which charging gun is rotated for charging operation according to the position of the charging socket of the vehicle parked in the adjacent parking space. In this way, a few charging guns can cover the majority of parking spaces, which reduces the layout cost of the charging guns and can reduce the investment in new energy charging equipment to a certain extent.

[0019] 4. The orderly charging system for electric vehicles of the present invention aims to solve the problem of charging electric vehicles when there are many electric vehicles that need to be charged. A charging loop is set between a plurality of charging parking spaces arranged side by side. The charging loop is a conveying line with a conveyor belt or a conveyor roller, which can queue up the vehicles to be charged. In addition, a plurality of vertical transport positions are set on the charging loop. In order to further alleviate the congestion problem when many vehicles are charged, the charging loop is set to three layers, namely, a charging layer, a vehicle full layer and an emergency vehicle pick-up layer. Under normal conditions, the electric vehicles that need to be charged are located at the charging layer, and the charging loop is vertically connected to the charging layer. The transport position can vertically transport the vehicle to the vehicle charging layer or the emergency pick-up layer according to the charging status of the electric vehicle. When the battery is fully charged, the vertical transport position will transport the vehicle to the vehicle charging layer. When the owner needs an emergency vehicle due to special reasons, the vehicle will be transported to the emergency pick-up layer and the vehicle information will be sent to the owner's APP. The owner then arrives at the designated location to pick up the vehicle according to the actual number of layers of the vehicle. This setting can not only charge a larger number of vehicles, but also avoid charging congestion when there are a large number of vehicles. The circular conveying charging route and the vertical transport route are combined, so that electric vehicles can be charged in an orderly manner more efficiently.

[0020] 5. The present invention is provided with blocking plates capable of cooperating with the transport roller platform around several vertical transport positions of the orderly charging system for electric vehicles. The blocking plate can be in an upright state when the transport roller platform leaves the layer to be charged, and can be in a horizontal state after the transport roller platform reaches the layer to be charged, thereby preventing surrounding vehicles from entering and ensuring charging safety. In addition, the transport roller platform includes a platform body, a left extension platform and a right extension platform. The left extension platform and the right extension platform include a plurality of trapezoidal intermediate boss structures, and the support rod structures with trapezoidal structures arranged on the other side of the blocking plate are mutually engaged, so that when the transport roller platform moves downward, the blocking plate is in an upright state, and after the transport roller platform moves upward, the blocking plate returns to a horizontal state.

DETAILED DESCRIPTION

[0040] The present invention is further described below in conjunction with the examples. However, the present invention is not limited to the following examples. The implementation conditions used in the examples can be further adjusted according to the different requirements of specific use, and the implementation conditions not specified are conventional conditions in the industry. The technical features involved in each embodiment of the present invention can be combined with each other as long as they do not conflict with each other.

[0041] The definitions of the relevant terms in the present invention are as follows:

[0042] Charging power: The instantaneous electric power output by the electric vehicle charging equipment during the charging process of the electric vehicle.

[0043] Coordinated charging: Regulating the charging behavior of electric vehicle users and the charging power of electric vehicle charging equipment according to certain strategies.

[0044] Coordinated charging equipment: Electric vehicle charging equipment capable of receiving and executing coordinated charging control strategies.

[0045] Coordinated charging management system: A system that can formulate and issue coordinated charging control strategies, collect grid load information, and monitor charging.

[0046] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figure 1-8 As shown, an orderly charging system for electric vehicles is composed of a power grid, an orderly charging management system, a charging pile, an electric vehicle and a mobile phone APP for car owners. The orderly charging management system is communicated with the power grid, the charging pile and the mobile phone APP for car owners. The orderly charging management system generates an orderly charging control strategy based on the vehicle information of the electric vehicle, the power grid regulation information, and the operation information of the charging equipment (charging pile), controls the start and stop time of the orderly charging equipment and the output power of the charging process, and carries out orderly charging operations.

[0049] The charging pile is a pile that supports orderly charging and has the function of information exchange with the orderly charging management system, including but not limited to AC charging piles and other types, and the charging piles should meet the requirements of their respective national standards. The charging piles and electric vehicles can be charged in an orderly manner through the control methods specified in charging mode 3 (AC charging) or charging mode 4 (DC charging) of GB / T 18487.1. The charging pile has the function of real-time adjustment of the available load current of the electric vehicle power supply equipment in Article 5.2.2.2 of GB / T 18487.1: the PWM wave duty cycle output by the charging pile using charging mode 3 should be able to respond to the control of the orderly charging management system, and the charging pile using charging mode 4 should be able to respond to the control of the orderly charging management system through the communication protocol. Other specific control strategies such as sleep wake-up, etc., shall be determined by the charging equipment manufacturer and the vehicle manufacturer through consultation.

[0050] Electric vehicle owners submit charging requirements to the orderly charging management system through mobile phone APP or electric vehicles and obtain feedback. The communication link can use 4G / 5G, Bluetooth, CAN bus or other. When electric vehicles use charging mode 3 (AC charging) of GB / T 18487.1 for orderly charging, the time to respond to the charging power adjustment command should be ≤5s.

[0051] Figure 1 In the architecture, the communication modes that can be used by each communication link are shown in Table 1 but are not limited to those shown in Table 1.

[0052] Table 1 Communication methods between subsystems of ordered charging

[0053]

[0054] In order to complete the connection between different orderly charging management systems, charging piles and electric vehicles, the orderly charging system can add a gateway. When the communication network cannot support orderly charging, ordinary charging methods can be used for charging.

[0055] Furthermore, the data interaction functions are as follows:

[0056] The orderly charging management system has but is not limited to the following functions:

[0057] (1) It can communicate with the charging pile, electric vehicle (or the owner's mobile phone APP), determine whether the communication is normal, and give a prompt if the communication fails;

[0058] (2) Capable of starting and stopping charging equipment in an orderly manner, setting functions, deploying equipment control strategies, and managing equipment;

[0059] (3) It can monitor the power supply / charging load, charging equipment status, vehicle status and other information in the jurisdiction in real time, and perform fault classification management on charging piles. If the alarm level is reached, it can prompt an alarm and perform corresponding processing;

[0060] (4) Ability to store data on orderly charging services and provide query and analysis;

[0061] (5) Able to respond to the charging needs of electric vehicle owners in a timely manner, complete information exchange with owners, and provide feedback on charging status and cost information;

[0062] (6) It can exchange information with the power grid, including but not limited to grid dispatch information, distribution operation information, time-of-use electricity prices, load forecast information, etc.

[0063] The charging pile (charging equipment) has but is not limited to the following functions:

[0064] (1) It should be able to communicate normally with the orderly charging management system, follow the scheduling of the orderly charging management system, and execute the functions deployed by the orderly charging management system; when communication with the orderly charging management system is lost, it should be able to continue to execute the original charging operation, save the necessary charging parameters, and have the ability to respond to different levels of faults;

[0065] (2) It can communicate normally with electric vehicles, perform normal charging operations on electric vehicles as required, and collect charging status information of electric vehicles and forward it to the orderly charging management system;

[0066] (3) It can record and upload the status of the charging pile and identify the fault level of the charging pile.

[0067] Electric vehicles (owner's mobile phone APP) have but are not limited to the following functions:

[0068] (1) It can communicate normally with the orderly charging management system, send charging requirements, connect to the corresponding charging piles according to the system arrangement, and complete the selection and confirmation of electric vehicles and charging piles; in the case of premature interruption of charging, it can submit an application to the system, terminate the charging process and complete the settlement as required;

[0069] (2) It can communicate normally with the charging pile and interact correctly throughout the charging process to complete the charging process; if charging is interrupted in advance, it can correctly and safely cut off the charging connection with the charging pile;

[0070] (3) Able to handle fault classification, and report and handle charging faults.

[0071] Furthermore, the data interaction protocol is as follows:

[0072] The data connection protocol between the orderly charging management system and the charging pile is shown in Table 2:

[0073] Table 2 Connection protocol of orderly charging management system → charging pile

[0074]

[0075] The data connection protocol between the charging pile and the orderly charging management system is shown in Table 3:

[0076] Table 3 Connection protocol of charging pile → orderly charging management system

[0077]

[0078] In addition, if Figure 2 As shown, the power-on connection process of the orderly charging management system is as follows: the charging pile control power is turned on, the orderly charging management system sends a connection command to the charging pile, and determines whether no feedback is received for more than 1s. If no feedback is received for more than 1s, it is determined whether it has been connected 3 times. If it has been connected 3 times, it is recorded that the charging pile is in a lost state and a notification is given to troubleshoot. If it has not been connected 3 times, the orderly charging management system sends a connection command to the charging pile. If no feedback is received for more than 1s, the orderly charging management system sends a self-test command to the charging pile. If the self-test fails, it is recorded that the charging pile is in a lost state and a notification is given to troubleshoot. If the self-test passes, it is determined whether there is a queued charging application. If so, the charging process is entered, and if not, the sleep process is entered.

[0079] The power-on connection process of the charging pile is as follows: receive the charging pile connection command, then send a connection response message to determine whether the self-test command is received. If not, continue to determine. If a self-test command is received, perform the self-test operation, then send the self-test result, and wait for the charging or sleep command.

[0080] like Figure 3As shown, the sleep process of the orderly charging management system and the charging pile is as follows: the orderly charging management system sends a sleep command to determine whether the charging pile responds, and the charging pile enters sleep when it responds; if there is no response, it is determined whether the response is three times. If it does not reach three times, it continues to determine whether the charging pile responds. If it responds three times, the loss of connection status of the charging pile is recorded and a notification is given to troubleshoot the problem.

[0081] Specifically, the sleep protocol from the orderly charging management system to the charging pile is shown in Table 4:

[0082] Table 4 Orderly charging management system → charging pile sleep protocol

[0083]

[0084] In addition, the sleep protocol from the charging pile to the orderly charging management system is shown in Table 5:

[0085] Table 5 Charging pile → Sleep protocol of orderly charging management system

[0086]

[0087] In addition, if Figure 4 As shown, the wake-up process of the orderly charging management system and the charging pile is as follows: the orderly charging management system sends a wake-up command and determines whether it has received any feedback for more than 5 seconds. If so, the charging pile is recorded as disconnected and a fault is notified for troubleshooting. If not, the charging pile is made to feedback the current status and wait for the next instruction.

[0088] Table 6 illustrates the wake-up protocol from the orderly charging management system to the charging pile:

[0089] Table 6 Orderly charging management system → charging pile wake-up protocol

[0090]

[0091] The wake-up protocol from the charging pile to the orderly charging management system is shown in Table 7:

[0092] Table 7 Charging pile → wake-up protocol of orderly charging management system

[0093]

[0094]

[0095] like Figure 5As shown, it illustrates the charging process of the orderly charging management system and the charging pile: the orderly charging management system controls the vehicle to lock and send charging parameters, and determines whether no feedback is received for more than 1s. If so, it records the disconnection status of the charging pile and notifies to troubleshoot; if not, it determines whether the charging status is received on time. If not, it records the disconnection status of the charging pile and notifies to troubleshoot. If so, it determines whether charging is completed. If charging is not completed, it returns to determine whether the charging status is received on time. If charging is completed, it determines whether there is a queued charging application. If so, it returns to the orderly charging management system to control the vehicle to lock the concurrent charging parameters, and performs log processing when determining whether charging is completed. If there is no queued charging application, it enters the sleep process.

[0096] The charging protocol from the orderly charging management system to the charging pile is shown in Table 8, and the charging protocol from the charging pile to the orderly charging management system is shown in Table 9:

[0097] Table 8 Orderly charging management system → Charging protocol of charging pile

[0098]

[0099] Table 9 Charging protocol of charging pile → orderly charging management system

[0100]

[0101] Once a charging pile's more serious fault or severe fault is reported in the form of an event trigger, the orderly charging management system will enter the fault management process and decide whether to cut off the high and low voltage relays depending on the fault level.

[0102] like Figure 6 As shown, the connection process between the orderly charging management system and the vehicle is as follows:

[0103] The electric vehicle or the owner submits a connection request and determines whether there is no response for more than 1s. If so, further determine whether the connection is more than 5 times. If so, change the manual service or replace the charging pile. Otherwise, return to the electric vehicle or the owner to submit the connection request. If the judgment of whether there is no response for more than 1s is no, the electric vehicle or the owner selects the charging pile in the APP, and then continues to determine whether to charge first and then pay. If it is charging first and then paying, the vehicle is connected to the charging pile, and it is determined whether the connection is completed. After the connection is completed, the charging process begins; if it is not charging first and then paying, it is determined whether the payment is completed, until the payment is completed, the vehicle is connected to the charging pile.

[0104] After receiving the owner's connection request, the orderly charging management system sends the latest charging pile information to determine whether the owner's selection result has been received. After receiving it, it determines whether the charging pile is in sleep mode. If the charging pile is in sleep mode, it enters the wake-up process to wait for the vehicle to connect. If the charging pile is not in sleep mode, it waits for the vehicle to connect and determines whether the vehicle and the charging pile are correctly connected. If they are correctly connected, it enters the charging process. If not, it further determines whether 10 minutes have passed. If so, it enters the sleep process. Otherwise, it returns to wait for the vehicle to connect.

[0105] Sometimes when the car owner needs to temporarily cut off the power due to an emergency, the orderly charging management system and the vehicle need to enter the forced disconnection process. The specific orderly charging management system and the vehicle's forced disconnection process are as follows: Figure 7 As shown:

[0106] The car owner sends a forced power-off request to determine whether the system responds. If not, the owner contacts the manual customer service or requests again. If the system responds, the owner determines whether to charge first and pay later. If so, the owner is asked to pay. If not, the owner determines whether the vehicle is unlocked and drives away after the vehicle is unlocked.

[0107] The orderly charging management system receives the disconnection request and sends a notification to the charging pile to stop charging. After the charging pile is ready, the high-voltage relay is powered off to determine whether the payment is made after charging. If so, it determines whether the payment is completed. After the payment is completed, it determines whether the vehicle is unlocked. If it is not charged first and then paid, it also enters the process of determining whether the vehicle is unlocked, and then notifies the owner to update the log and enter the sleep process.

[0108] like Figure 8 As shown, the process of completing charging is as follows: after the orderly charging management system receives the charging completion notification, it connects to the owner's APP and enters the step of determining whether there is no response for more than 1s. If so, it determines whether the connection exceeds 5 times. If not, it enters the step of sending the charging result status to the owner. When it is determined that the connection exceeds 5 times, it contacts the manual customer service. If not, it continues to enter the step of connecting to the owner's APP. After entering the step of sending the charging result status to the owner, it determines whether the payment is made after charging. If so, it determines whether the payment is successful. After the payment is successful, it enters the step of notifying the charging pile to disconnect the cable or disconnect the locking device. If the result of determining whether the payment is made after charging is no, it also enters the step of notifying the charging pile to disconnect the cable or disconnect the locking device, and then determines whether to disconnect. After disconnection, the vehicle drives away, the charging pile goes into sleep, and finally the log is updated.

[0109] The connection protocol between the orderly charging management system and the owner's APP or vehicle computer is shown in Table 10:

[0110] Table 10 Connection protocol between the orderly charging management system and the car owner's APP or car computer

[0111]

[0112]

[0113] The charging process between the charging pile and the car owner's APP or car computer refers to the national standard GB / T 27930-2023; the entire charging process includes physical connection completion, low-voltage auxiliary power-on, charging handshake stage, charging parameter configuration stage, charging stage and charging end stage. After the physical connection is completed and low-voltage auxiliary power-on, the two parties begin to communicate. During this period, if the charging pile and the vehicle fail to correctly receive the other party's message within the specified time, it is considered a timeout.

[0114] Handshake phase between charging pile and vehicle: After the physical connection is completed, the vehicle and charging pile are locked to each other, the low-voltage auxiliary power supply circuit is turned on, and a handshake message is sent.

[0115] Example 2

When the charging gun needs to be used for charging, the charging gun on the charging gun guide slide 18 is pulled out, and finally the charging gun is inserted into the charging port of the electric vehicle.

[0118] The charging gun ring track 4 is a deformable ring track. By adjusting the lengths of the telescopic cylinder 1 12, the telescopic cylinder 2 13, the telescopic cylinder 3 14 and the telescopic cylinder 4 15, the charging gun ring track 4 can be switched between a circle and an ellipse. Fig.12 As shown, when the charging gun ring track 4 is circular, its radius is R, and when the charging gun ring track 4 is elliptical, its major axis is a, its minor axis is b, and b <R<a。

[0119] like Fig.19As shown, the charging gun guide slide 18 includes a C-shaped slide 19 and a guide cylinder 20. The C-shaped slide 19 is covered and arranged on the outer side of the charging gun ring rail 4. The charging gun ring rail 4 and the guide cylinder 20 are respectively arranged on both sides of the C-shaped slide 19. Through the above arrangement, the charging cable on the charging cable drum 9 can be conveniently immersed in the guide cylinder 20 without interfering with the charging ring frame 10, and the cable arrangement can be flexibly realized. In addition, a driving wheel capable of sliding along the charging gun ring rail 4 is also provided on the inner side of the C-shaped slide 19 (not shown in the figure, the driving wheel structure may be a roller driven by a motor to rotate, the roller is in contact with the charging gun ring rail, and the C-shaped slide 19 is able to move freely on the charging gun ring rail 4 through the rotation of the roller), so that the parking position of the charging gun guide slide 18 can be selected according to the parking posture of the electric vehicle on the charging parking space 1 or the general parking space 2, so that the position of the charging gun can be better adjusted according to the position of the charging port of the electric vehicle, and the charging of the electric vehicle can be better realized.

[0120] Preferably, in order to facilitate the charging gun ring rail 4 to extend out of the upper disc shell 8 when it becomes elliptical, a clearance groove 62 is opened on the side wall of the upper disc shell 8.

[0122] Furthermore, the charging gun guide slide 18 can be provided in a plurality, and correspondingly, the charging gun can also be provided in a plurality, preferably, it can be provided in 2-3.

[0123] Example 3

[0124] like Figure 13-18 As shown, if the number of cars 24 to be charged far exceeds Fig. 9 If several charging parking spaces 1 and general parking spaces 2 are set, then Fig.13 As shown, it is necessary to add several charging loops 21, each charging loop 21 takes the charging parking space 1 as the center, and the general parking spaces 2 on the left and right sides of the charging parking space 1 as the endpoints to form a closed loop, and a charging parking space 1 is arranged between adjacent closed loops. The charging loop 21 is as shown in FIG. Fig.14As shown, they all include three layers: from top to bottom, there are a charging layer 37, a vehicle full layer 38 and an emergency vehicle retrieval layer 29. The charging loop 21 includes an upper charging loop 1 22 and a lower charging loop 23.

The third vertical transport position 33 is provided on the third vertical track 28, a plurality of fourth vertical transport positions 34 are provided on the second transverse track 29, a plurality of sixth vertical transport positions 36 are provided on the fourth vertical track 30, and the electric vehicles can be transported from the waiting charging layer 37 to the vehicle charging layer 38 and the emergency vehicle retrieval layer 29 through the first vertical transport position 31, the second vertical transport position 32, the third vertical transport position 33, the fourth vertical transport position 34, the fifth vertical transport position 35 and the sixth vertical transport position 36, so as to avoid charging congestion and to avoid charging congestion when the electric vehicles need to be charged. When the vehicle is full, the owner can just go to the full vehicle layer 38 to pick up the vehicle. When the vehicle is still in the queue or is charging and needs to be picked up urgently, the owner can perform corresponding operations on the APP, and then the owner can just go to the emergency pick-up layer 29 to pick up the vehicle. Through the above arrangement, the electric vehicle can be efficiently charged through the circular charging loop 21 during charging, and can also be combined with the vertical space to avoid crowding of vehicles on the same layer, so that the charging system can orderly charge electric vehicles with larger capacity and load.

[0125] like Figure 15-17As shown, the first vertical transport position 31, the second vertical transport position 32, the third vertical transport position 33, the fourth vertical transport position 34, the fifth vertical transport position 35 and the sixth vertical transport position 36 are provided with an opening 1 40 on the emergency vehicle retrieval layer 39, an opening 2 41 on the vehicle filling layer 38, and an opening 3 42 on the charging layer 37, and the opening 1 40, the opening 2 41 and the opening 3 42 overlap in the vertical direction, and a vehicle lifting and transporting platform 43 is provided at the first vertical transport position 31, the second vertical transport position 32, the third vertical transport position 33, the fourth vertical transport position 34, the fifth vertical transport position 35 and the sixth vertical transport position 36, and the vehicle lifting and transporting platform 43 can move between the opening 1 40, the opening 2 41 and the opening 3 42.

[0126] The vehicle lifting and transporting platform 43 includes a transport roller platform 45 and a scissor lift frame 44. The scissor lift frame 44 is lifted and lowered by a lifting drive mechanism such as a lifting cylinder or a lifting motor (the specific structure of the lifting cylinder or the lifting motor is common knowledge in the art and will not be described in detail here). The transport roller platform 45 includes a platform body 46 and a left extension platform 47 and a right extension platform 48 arranged on both sides of the platform body 46. A left blocking plate group 49 engaged with the left extension platform 47 and a right blocking plate group 50 engaged with the right extension platform 48 are arranged around the opening three 42. The left blocking plate group 49 and the right blocking plate group 50 can be as Fig.18 As shown in (b), it is in an upright state, so that when the vehicle lifting and transporting platform 43 is vertically lifted and transported, the charging loop 21 can be isolated from the entry of the external vehicles 24 to be charged, which can make charging safer.

[0127] The left extension platform 47 and the right extension platform 48 have the same structure, and include a first boss 51, a plurality of intermediate bosses 53 and an end boss 52 from top to bottom, a gap one is set between the first boss 51 and the intermediate boss 53, a gap two is set between the plurality of intermediate bosses 53, and a gap three is set between the intermediate boss 53 and the end boss 52. The left blocking plate group 49 and the right blocking plate group 50 have the same structure, and both include a flip plate body 54, an articulated rotating shaft 55, a locking telescopic pin one 58 and a locking telescopic pin two 61. The flip plate body 54 is rotatably arranged at the periphery of the opening three 42 through the articulated rotating shaft 55. The flip plate body 54 is bounded by the articulated rotating shaft 55, and the flip plate body 54 on the side away from the opening three 42 is defined as a blocking plate 56, and the flip plate body 54 close to the opening three 42 is defined as a support rod 57. There are several support rods 57, which can fill the gap one, the gap two and the gap three respectively.

[0128] The support rod 57 is an isosceles trapezoid 1 that is small at the top and large at the bottom. The first boss 51 is a trapezoidal structure with a straight side on the left and a hypotenuse on the right. The middle boss 53 is an isosceles trapezoid 2 that is large at the top and small at the bottom and is connected to the support rod 57. The end boss 52 is a trapezoidal structure with a hypotenuse on the left and a right-angled side on the right.

In addition, in order to facilitate the resetting of the flip plate body 54, a resetting torsion spring or a resetting spring is further provided on the hinged rotation axis 55, which can be reset after the locking telescopic pin 2 61 is unlocked.

[0130] Specifically, the actions of the locking telescopic pin 1 58 and the locking telescopic pin 2 61 are adapted to the actions of the vehicle lifting and transporting platform 43. Before the vehicle lifting and transporting platform 43 descends and leaves the opening 3 42, the locking telescopic pin 1 58 is retracted. After the locking telescopic pin 1 58 is disengaged from the locking groove 1 59, the flip plate body 54 can freely rotate along the hinged rotation axis 55. When the transport roller platform 45 is driven to descend by the scissor lift 44, the left extension platform 47 and the right extension platform 48 drive the support rod 57 to rotate downward. The baffle plate 56 is finally in an upright state. At this time, the locking telescopic pin 2 61 is extended and inserted into the locking groove 2 60, thereby locking the baffle plate 56. At this time, the baffle plate 56 can form a safe working space to ensure the safety of vehicle charging. After the transport roller platform 45 is lifted and returned to the opening 3 42, the locking telescopic pin 2 61 is driven to retract and leave the locking groove 2 60. The reset torsion spring or reset spring is actuated to drive the flip plate body 54 back to a horizontal position, and then the locking telescopic pin 1 58 is extended and inserted into the locking groove 1 59.

[0131] Preferably, the first vertical track 25, the first transverse track 26 and the second vertical track 27, the lower charging loop line 23 includes a third vertical track 28, a second transverse track 29 and a fourth vertical track 30, the first vertical track 25, the first transverse track 26 and the second vertical track 27 are provided with conveyor belts or conveyor rollers, so as to realize the transportation of vehicles, and the platform body 46 is also provided with conveyor rollers or conveyor belts, and the conveyor rollers or conveyor belts are provided with driving sources, such as a rotary drive motor or a rotary drive motor, so that the horizontal transportation of the vehicle can be controlled.

[0132] In order to facilitate technicians in the field to better understand the charging process of the charging parking space with a charging loop, Fig.13The charging method is described as follows: when there are many cars 24 to be charged, which are obviously more than the charging parking space 1 and the general parking space 2, and it is necessary to queue for charging, the cars 24 to be charged are made to queue outside the charging loop 21. The position of the cars 24 to be charged can be achieved by setting a parking robot (the specific parking robot is common knowledge in the art, such as the parking robot in CN209924535U). The cars 24 to be charged preferably enter the upper charging loop 1 22 from the first transverse lane 26 and / or the second vertical lane 27, and the cars 24 to be charged preferably enter the lower charging loop 2 23 from the second transverse lane 29 and / or the fourth vertical lane 30. In addition, when the electric car in the general parking space 2 on the left side of the charging parking space 1 in the charging loop 21 is fully charged, it is moved to the first vertical transport position 31 by the parking robot or by the drive roller set on the general parking space 2, and then transported to the first vertical transport position 31. The vehicle lifting and transporting platform 43 transports the electric vehicle to the vehicle filling layer 38, and at the same time, the blocking plate 56 located at the charging layer 37 is erected to isolate other vehicles and prevent vehicles from entering by mistake. After the vehicle arrives at the vehicle filling layer 38, the parking robot moves the vehicle to the designated position, and then sends it to the car owner APP to notify the car owner to pick up the car; preferably, the first vertical transport position 31 is rotated to the first vertical lane 25 close to the general parking space 2, and the parking robot moves the car 24 to be charged to the first horizontal lane 26, the second vertical lane 27, the second horizontal lane 29 and the fourth vertical lane 30 according to the charging sequence according to the instruction. When the car owner suddenly has an emergency and does not need to charge and needs to use the car immediately, the second vertical transport position 32 and / or the third vertical transport position 33 is activated to transport the electric vehicle to the emergency pick-up layer 39, and then the parking robot is also used to stop the vehicle to the designated position, and then the vehicle is sent to the car owner APP to notify the car owner to pick up the car.

[0133] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them.
