Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric vehicle charging, in particular to an electric vehicle orderly charging system. BACKGROUND

[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 an electric vehicle non-inductive orderly charging method, which collects historical occupation information of each schedulable charging pile in each period and performs optimal charging coefficient analysis, sorts the schedulable charging piles according to the optimal charging coefficient YC, and selects the appropriate target charging pile for charging. The orderly charging method does not have a supporting vehicle charging device, and when many vehicles are charging, it completely relies on software support, which also makes it difficult for electric vehicles to charge. For example, patent document 2 (CN118544855A) discloses an intelligent charging pile for new energy vehicles, which is provided with a suspended charging gun on the charging space. The charging gun can dynamically adjust the position of the charging gun according to the position of the vehicle on the charging space, so that the charging gun can well adapt to the charging port of the new energy vehicle. However, it can only charge a single vehicle on a single parking space, and if the vehicle is not timely after charging, the charging gun cannot be well utilized, causing charging waste. Finally, for example, patent document 3 (CN114248648A) discloses a self-service gun pulling and moving vehicle charging station for electric vehicles, which is provided with an electric vehicle charging position and an electric vehicle standby position. The transmission belt structure is used to move the electric vehicle from one parking space to another. When the electric vehicle is not timely after charging, the transmission belt structure is used to charge the next electric vehicle. However, this method can only charge a few vehicles, and when there are many vehicles, it cannot well achieve orderly charging of multiple vehicles. In addition, it does not consider how to arrange efficient and reasonable charging plans for multiple vehicles.

[0003] In summary, the prior art has addressed the orderly charging of electric vehicles by optimizing the relevant parameters of charging piles. However, there is no charging system that can efficiently charge a large number of vehicles in conjunction with orderly charging, nor is there a system that can intelligently charge a charging gun in one parking space by changing the shape of the charging rail. In addition, there is no consideration of quickly retrieving a vehicle when a car owner urgently needs to use the vehicle during charging. To this end, the present invention provides a charging gun travel rail whose shape can be deformed according to the charging situation, so that the vehicle in the charging parking space can be fully charged without leaving and affecting charging. By changing the charging gun travel rail from a circular shape to an elliptical shape, the charging gun can be extended into an adjacent parking space, thereby converting the adjacent parking space into a charging space. In addition, considering the timely retrieval of the vehicle during charging, three layers of vehicle retrieval layers are provided accordingly, thereby diverting vehicles and preventing vehicles from concentrating on a certain layer and causing congestion. In addition, combined with a conveyor belt structure, an orderly charging system for electric vehicles with a reasonable layout for charging a large number 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; 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. 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 manual service or replace the charging pile. Otherwise, return to the electric vehicle or the owner to submit the connection request. If it is determined whether there is no response for more than 1s and the answer 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 pay later. If it is to charge first and pay later, 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 to charge first and pay later, 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 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.

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

[0009] If there is no response, contact the manual customer service or request again. If the system responds, it determines whether the payment is made after charging. If so, the owner is asked to pay. If not, it determines whether the vehicle is unlocked and drives 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, and it is determined whether the payment is completed after charging. If so, it is determined whether the payment is completed. After the payment is completed, it is determined whether the vehicle is unlocked. If it is determined that the payment is not completed 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 determines 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 it is charging first and then paying. 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 from the locking device. If the result of determining whether it is charging first and then paying is no, it also enters the step of notifying the charging pile to disconnect the cable or disconnect from the locking device, and then determines whether to disconnect. After disconnection, the vehicle drives away, the charging pile goes into sleep, and finally updates the log.

[0012] Preferably, the charging pile of the electric vehicle orderly charging system is installed on the charging parking space, and also includes a general parking space adjacent to the charging parking space.

The charging gun ring rail can be switched between circular and elliptical. When the charging ring rail is elliptical, the charging gun can slide along the charging gun ring rail to the position of the 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 the general parking space.

[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 at intervals between adjacent closed loops, and the charging loops include three layers: from top to bottom, there is a layer to be charged, 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.

[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 for electric vehicles of the present invention includes an orderly charging management system, which can realize the orderly charging control strategy formulation, downstream and power grid load information collection, and charging monitoring functions. The orderly charging management system is connected to 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, 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 queue 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 electric vehicle orderly charging system of the application, the charging pile of which fully considers that, in addition to being able to flexibly charge the vehicle parked in the parking space, it is also able to deform the charging pile in the charging parking space, so that the charging gun of the charging pile of the charging parking space is able to cover the adjacent non-charging parking space, thereby being able to realize charging operation in the non-charging parking space by arranging a small number of charging parking spaces, and since the omnibearing coverage of the charging gun is realized by setting the rail structure capable of deforming, compared with the prior art of simply using the charging wire of the charging parking space to charge the adjacent parking space, the arrangement of the charging wire is more secure, and in addition, since the charging wire is suspended, it is equivalent to re-installing a new charging parking space in the non-charging parking space, which is more secure, convenient and less investment.

[0018] 3、The charging pile of the application, by setting the deformable charging ring frame at the disc-shaped charging end, the charging gun ring rail provided with a plurality of charging gun guide slides is able to change between an ellipse and a circle, by setting the shape change of the charging gun ring rail, the charging gun guide slide provided with the charging gun is able to slide along the elliptical charging gun ring rail, and the long side of the ellipse extends to the half position of the adjacent parking space, so that the two elliptical charging ring rails of the two charging parking spaces cover the entire adjacent parking space, thereby being able to rotate the charging gun to perform charging operation according to the position of the charging socket of the vehicle parked in the adjacent parking space, so that a small number of charging guns are able to cover a large number of parking spaces, which reduces the arrangement cost of the charging guns and is able to 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 can still meet the charging problem of electric vehicles when there are many electric vehicles that need to be charged. A charging loop is set between multiple 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 cars to be charged. In addition, a number of vertical transport positions are set on the charging loop. In order to further alleviate the congestion problem when many vehicles are charging, the charging loop is set into three layers, namely, the charging layer, the vehicle full layer and the emergency vehicle pick-up layer. Under normal conditions, the electric vehicles that need to be charged are located at the charging layer, and the vertical transport positions are used to transport the cars to the charging layer. The transport position can vertically transport the vehicle to the vehicle full 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 full 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 many vehicles. The circular transportation charging route and the vertical transportation 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 that can cooperate with the transport roller platform around several vertical transport positions of the orderly charging system of 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 structure with a trapezoidal structure provided on the other side of the blocking plate is 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.

[0040] The present invention is further described below with reference to the following examples. However, the present invention is not limited to the following examples. The implementation conditions used in the examples may be further adjusted according to the specific requirements of the application. Unspecified implementation conditions are conventional conditions in the industry. The technical features involved in the various embodiments of the present invention may 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 consists of a power grid, an orderly charging management system, charging piles, electric vehicles and a car owner's mobile phone APP. The orderly charging management system is communicated with the power grid, charging piles 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 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] Charging piles must support orderly charging and have the ability to exchange information with an orderly charging management system. These include, but are not limited to, AC charging piles and must meet the requirements of their respective national standards. Charging piles and electric vehicles can be charged in an orderly manner using the control methods specified in Charging Mode 3 (AC charging) or Charging Mode 4 (DC charging) of GB / T 18487.1. Charging piles must also have the function of real-time adjustment of the available load current of electric vehicle power supply equipment as specified in Section 5.2.2.2 of GB / T 18487.1: For charging piles using Charging Mode 3, the duty cycle of the PWM wave output must be responsive to the control of the orderly charging management system. For charging piles using Charging Mode 4, the duty cycle must be responsive to the control of the orderly charging management system via a communication protocol. Other specific control strategies, such as sleep and wakeup, are determined through consultation between the charging equipment manufacturer and the vehicle manufacturer.

[0050] Electric vehicle owners submit charging requests to the orderly charging management system and receive feedback through a mobile phone app or their electric vehicle. The communication link can use 4G / 5G, Bluetooth, CAN bus, or other methods. When electric vehicles are orderly charged using charging mode 3 (AC charging) of GB / T 18487.1, the response time for charging power adjustment commands should be ≤ 5s.

[0051] Figure 1 In the architecture, the communication modes that can be adopted 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 be added with 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 station, electric vehicle (or the owner's mobile phone APP), can determine whether the communication is normal, and can give a prompt if the communication fails;

[0058] (2) Able to complete the functions of orderly charging equipment start and stop, function setting, equipment control strategy deployment, equipment management, etc.;

[0059] (3) It can monitor the power supply / charging load, charging equipment status, vehicle status and other information within the jurisdiction in real time, and carry out fault classification management of 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) Ability to respond to the charging needs of electric vehicle owners in a timely manner, complete information exchange with owners, and feedback 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 receive 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 pile 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, 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 controls the power 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 determines whether it has been connected 3 times. If it has been connected 3 times, it records that the charging pile is in a disconnected state and notifies 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, it sends a self-test command to the charging pile. If the self-test fails, it records that the charging pile is in a disconnected state and notifies to troubleshoot. If the self-test passes, it determines whether there is a queued charging application. If so, it enters the charging process. If not, it enters the sleep process.

[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, determine whether the self-test command is received, if not, continue to judge, if the self-test command is received, perform the self-test operation, and then send the self-test result, waiting 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 charging pile loss status 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, it records the disconnection status of the charging pile and notifies the fault investigation. If not, it makes the charging pile feedback the current status and waits 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 charging pile loss status and notifies the fault investigation; if not, it determines whether the charging status is received on time. If not, it records the charging pile loss status and notifies the fault investigation. 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 serious fault or severe fault of a charging pile 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 1 second. If so, it further determines whether the connection has been made more than 5 times. If so, it changes to manual service or replaces the charging pile. Otherwise, it returns to the electric vehicle or the owner to submit the connection request. If it is determined whether there is no response for more than 1 second and the answer 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 pay later. If it is to charge first and pay later, 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 to charge first and pay later, 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 and waits 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 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 charging process. The specific orderly charging management system and the vehicle's forced charging 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 manual customer service or requests again. If the system responds, the owner is asked to pay after charging. If not, the owner is asked to unlock the vehicle and drive away after unlocking it.

[0107] 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 de-energized and it is determined whether the payment is completed after charging. If so, it is determined whether the payment is completed. After the payment is completed, it is determined whether the vehicle is unlocked. If it is not determined that the payment is completed 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.

[0108] like Figure 8 As shown, this is the process of completing charging: after the orderly charging management system receives the charging completion notification, it connects to the owner's APP and determines 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 it is charging first and then paying. 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 from the locking device. If the result of determining whether it is charging first and then paying is no, it also enters the step of notifying the charging pile to disconnect the cable or disconnect from the locking device, and then determines whether to disconnect. After disconnection, the vehicle drives away, the charging pile goes into sleep, and finally updates the log.

[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 owner's APP or vehicle computer

[0111]

[0112]

[0113] The charging process between the charging station and the vehicle's app or vehicle computer follows the national standard GB / T 27930-2023. The entire charging process includes physical connection, low-voltage auxiliary power-up, charging handshake, charging parameter configuration, charging, and the end of charging. After the physical connection is completed and low-voltage auxiliary power-up is initiated, communication begins between the two parties. If the charging station or vehicle fails to receive each other's messages within the specified time, it is considered a timeout.

[0114] Charging pile and vehicle handshake stage: 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

[0116] like Figure 9-12 As shown in FIG19 , the charging pile 3 of the orderly charging system for electric vehicles is installed on the charging parking space 1, and also includes a general parking space 2 adjacent to the charging parking space, such as Figure 9 As shown, there are several charging parking spaces 1 and general parking spaces 2, and the charging parking spaces 1 and general parking spaces 2 are arranged adjacent to each other in an alternating manner. The charging pile 3 includes a charging gun ring rail 4, and several charging guns (not shown in the figure) are slidably arranged on the charging gun ring rail 4. The charging gun ring rail 4 can be switched between a circle and an ellipse. When the charging ring rail 4 is elliptical, the charging gun can slide along the charging gun ring rail 4 to the position of the adjacent general parking space 2, so that the general parking space 2 can also be turned into a charging parking space 1, thereby realizing orderly charging of the electric vehicles in the general parking space 2.

[0117] like Figure 10-12As shown, the charging pile 3 includes a charging pile base 5, an L-shaped charging telescopic rod 6 and a disc-shaped charging terminal 7. The charging pile base 5 is arranged on the charging parking space 1, and the vertical end of the L-shaped charging telescopic rod 6 is slidably arranged on the charging pile base 5. The lateral end of the L-shaped charging telescopic rod 6 is provided with the disc-shaped charging terminal 7, and the disc-shaped charging terminal 7 includes an upper disc shell 8, a charging cable drum 9 and a charging ring frame 10. The upper end of the disc shell 8 is arranged at the lateral end of the L-shaped charging telescopic rod 6. The interior of the disc-shaped shell 8 is sequentially provided with a charging cable drum 9 and a charging ring frame 10. The charging ring frame 10 includes a fixed seat 11, a telescopic cylinder 12, a telescopic cylinder 2 13, a telescopic cylinder 3 14, a telescopic cylinder 4 15, a charging gun ring rail 4 and a charging gun guide slide 1 8. The telescopic cylinder 1 12, telescopic cylinder 2 13, telescopic cylinder 3 14 and telescopic cylinder 4 15 are evenly arranged along the circumference of the fixed seat 11. One ends of the telescopic cylinder 12, telescopic cylinder 2 13, telescopic cylinder 3 14 and telescopic cylinder 4 15 are all set on the fixed seat 11, and the other ends of the telescopic cylinder 12, telescopic cylinder 2 13, telescopic cylinder 3 14 and telescopic cylinder 4 15 are fixedly provided with the charging ring rail 4. The charging gun guide slide 18 is slidably set on the charging ring rail 4, and the charging gun (not shown in the figure) is set on the charging gun guide slide 18. The end of the charging gun is connected to the charging line on the charging cable drum 9. 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 length of the telescopic cylinder 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. Figure 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 Figure 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 arranged on the outside of the charging gun ring rail 4, and 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 that can slide 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 can be a roller driven by a motor to rotate, the roller is in contact with the charging gun ring rail, and the rotation of the roller enables the C-shaped slide 19 to move freely on the charging gun ring rail 4), 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.

[0121] Furthermore, a guide slot 16 is provided on the charging pile base 5, and a sliding protrusion 17 is provided at the vertical end of the L-shaped charging telescopic rod 6. The sliding protrusion 17 slides within the guide slot 16. The guide slot 16 preferably has a dovetail groove structure. A lifting drive device, such as a lifting and telescopic cylinder or a motor-driven screw structure, can be provided between the charging pile base 5 and the L-shaped charging telescopic rod 6 to achieve the lifting and lowering movement of the L-shaped charging telescopic rod 6 on the charging pile base 5.

[0122] Furthermore, the charging gun guide slides 18 can be provided in a plurality, and accordingly, the charging guns can also be provided in a plurality, preferably, 2-3.

[0123] Example 3

[0124] like Figure 13-18 As shown, if the number of cars 24 to be charged far exceeds Figure 9 Several charging parking spaces 1 and general parking spaces 2 are set, then Figure 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. There is a charging parking space 1 between adjacent closed loops. The charging loop 21 is as shown in FIG. Figure 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 upper charging loop 1 22 includes a first vertical lane 25, a first horizontal lane 26 and a second vertical lane 27. The lower charging loop 23 includes a third vertical lane 28, a second horizontal lane 29 and a fourth vertical lane 30. The first vertical lane 25, the first horizontal lane 26 and the second vertical lane 27 are connected in sequence. The lower end of the first vertical lane 25 is connected to the left side of the charging parking space 1. The lower end of the second vertical lane 27 is connected to the general parking space 2 on the right side of the charging parking space 1, the third vertical lane 28, the second horizontal lane 29 and the fourth vertical lane 30 are connected in sequence, the upper end of the third vertical lane 28 is connected to the general parking space 2 on the right side of the charging parking space 1, and the upper end of the fourth vertical lane 30 is connected to the general parking space 2 on the left side of the charging parking space 1. A plurality of first vertical transport positions 31 are provided on the first vertical lane 25, a plurality of second vertical transport positions 32 are provided on the first horizontal lane 26, and a plurality of third vertical transport positions 33 are provided on the second vertical lane 27. There are several fourth vertical transport positions 34 on the third vertical lane 28, several fifth vertical transport positions 35 on the second transverse lane 29, and several sixth vertical transport positions 36 on the fourth vertical lane 30. Electric vehicles can be transported from the waiting charging layer 37 to the vehicle full 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, thereby avoiding charging congestion and ensuring that electric vehicles can be charged when they are needed. When the vehicle is fully charged, it only needs to enter the charging loop 21. When the vehicle is fully charged, it only needs to 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 the corresponding operation on the APP, and then the owner only needs to go to the emergency pick-up layer 29 to pick up the vehicle. Through the above-mentioned settings, electric vehicles can be charged efficiently through the circular charging loop 21 during charging, and can also be combined with 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 full layer 38, and an opening 3 42 on the charging layer 37. The opening 1 40, the opening 2 41 and the opening 3 42 overlap in the vertical direction. 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. 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 this field and will not be described 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 shown after the platform body 46 leaves the opening three 42. Figure 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 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, from top to bottom, a first boss 51, several intermediate bosses 53 and an end boss 52. A gap one is set between the first boss 51 and the intermediate boss 53, a gap two is set between several 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 rotation axis 55, a locking telescopic pin one 58 and a locking telescopic pin two 61. The flip plate body 54 is rotatably arranged on the periphery of the opening three 42 through the articulated rotation axis 55. The flip plate body 54 is bounded by the articulated rotation axis 55. 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, gap two and gap three respectively.

[0128] The support rod 57 is an isosceles trapezoid 1 that is smaller at the top and larger 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 larger at the top and smaller 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.

[0129] like Figure 18 As shown, a locking groove 1 59 is provided at the end of the flip plate body 54 away from the hinged rotation axis 55, and a locking groove 2 60 is provided at the side end of the flip plate body 54. The locking retractable pin 1 58 can extend into the locking groove 1 59, and the locking retractable pin 2 61 can extend into the locking groove 2 60. The locking retractable pin 1 58 and the locking retractable pin 2 61 are both disposed around the opening 3 42. In addition, to facilitate the resetting of the flip plate body 54, a return torsion spring or return spring is provided on the hinged rotation axis 55 to reset the locking retractable pin 2 61 after it 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 transport platform 43. Before the vehicle lifting transport platform 43 descends and leaves the opening 3 42, the locking telescopic pin 1 58 retracts. After the locking telescopic pin 1 58 disengages from the locking groove 1 59, the flip plate body 54 can rotate freely 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 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 56. At this time, the baffle 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 the 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 lane 25, the first horizontal lane 26 and the second vertical lane 27, the lower charging loop line 23 includes a third vertical lane 28, a second horizontal lane 29 and a fourth vertical lane 30, and the first vertical lane 25, the first horizontal lane 26 and the second vertical lane 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 a driving source, 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 those skilled in the art to better understand the charging process of the charging parking space with a charging loop, Figure 13The charging method is described as follows: when there are more 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 this field, such as the parking robot in CN209924535U can be selected to achieve it). The cars 24 to be charged preferably enter the upper charging loop 1 22 from the first horizontal 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 horizontal lane 29 and / or the fourth vertical lane 30. In addition, when the electric car in the general parking space 2 to the left 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 transmission roller provided on the general parking space 2, and then transported from the first vertical transport position 31 to the lower charging loop 23. The vehicle lifting and transporting platform 43 transports the electric vehicle to the vehicle full 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 full layer 38, the parking robot moves the vehicle to the designated position, and then sends it to the owner APP to notify the owner to pick up the vehicle; 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 to be charged 24 to the first horizontal lane 26, the second vertical lane 27, the second horizontal lane 29 and the fourth vertical lane 30 in the order of charging according to the instructions. When the owner suddenly has an emergency and does not need to charge but needs to use the car immediately, the second vertical transport position 32 and / or the third vertical transport position 33 will be 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 at the designated position, and then send it to the owner APP to notify the owner to pick up the vehicle.

[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. It does not limit the scope of protection of the present invention. Any equivalent changes or modifications made based on the spirit of the present invention should be included in the scope of protection of the present invention.

If it is not determined that the payment is completed 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.

7. The orderly charging system for electric vehicles according to claim 6, characterized in that: 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 determines 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 it is charging first and then paying. 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 from the locking device. If the result of determining whether it is charging first and then paying is no, it also enters the step of notifying the charging pile to disconnect the cable or disconnect from the locking device, and then determines whether to disconnect. After disconnection, the vehicle drives away, the charging pile goes into sleep, and finally updates the log.
