Description

Technical Field

[0001] The present disclosure relates to the technical field of intelligent charging for electric vehicles, and particularly to a charging pile reservation method, device, system, and storage medium. Background Art

[0002] An electric vehicle refers to a vehicle that uses a power source such as a battery to provide at least part of its power. Electric vehicles need to be charged at charging piles. A charging pile is a device that supplies electrical energy to an electric vehicle. It is usually installed in places such as parking lots, gas stations, commercial areas, and residential areas. By connecting to the power grid, it converts alternating current or direct current into a current and voltage suitable for charging the battery of the electric vehicle, and connects to the electric vehicle through a charging interface to charge the battery of the electric vehicle. To facilitate users' charging, there is a charging pile reservation charging technology in the prior art.

[0003] In one prior art, before going to a charging location, the user uses an application on a mobile terminal such as a mobile phone to confirm information such as whether there are idle charging piles at the charging location, the numbers of the idle charging piles, and the idle time periods. Subsequently, the user makes a reservation for the existing idle charging piles through the application. Then, the user goes to the charging location at the reserved time and connects to the reserved charging pile to charge the vehicle. To protect the usage interests of reserved users, usually, other users are no longer allowed to make another reservation or use the reserved charging pile during a possibly conflicting time period. For example, even if a non-reserved user arrives at the reserved charging pile during this time period, the reserved charging pile is unavailable to this non-reserved user. Since the reservation operation is completed online, there is often no prompt at the scene that the charging pile has been reserved. The non-reserved user parks the vehicle at the scene, opens the application to prepare for charging, and only then learns through the application that the charging pile has been reserved and cannot be used. This causes the non-reserved user to have to find other available charging piles, which may lead to a poor user experience and low overall efficiency for the non-reserved user.

[0004] In addition, if the user parks and charges at other charging piles while having already reserved a charging pile, even if the charging pile is idle, the system often prompts that this charging pile is not the one reserved by the user and prompts the user to move to the reserved charging pile. This often makes the charging process not smooth and affects the usage experience of the reserved user.

[0005] Therefore, it is necessary to improve the charging pile reservation method to solve the above problems. Summary of the Invention

[0006] The present disclosure provides a charging pile reservation method, device, system, and computer-readable storage medium to solve the technical problem that when there are other idle charging piles in a charging station, the system cannot handle them flexibly, thus affecting the user experience.

[0007] According to a first aspect of the present disclosure, a charging pile reservation method is provided. The method includes: in response to a use request of a first user for a first charging pile at a charging station, querying whether the first charging pile is in a reserved state; if the first charging pile is in a reserved state reserved by a second user, querying whether there is an idle second charging pile in the charging station; if there is an idle second charging pile, changing the reservation of the second user to the second charging pile; and accepting the use request of the first user for the first charging pile.

[0008] Through the first aspect of the present disclosure above, even if the first charging pile has been reserved, in the case where there is an idle second charging pile, the reservation of the reserved user can be intelligently changed to the idle second charging pile. This change of reservation is shielded from the first user, or in this technical solution, the fact that the first charging pile is reserved and the reservation is changed to the second charging pile is not notified to the first user. Therefore, in the view of the first user, the first charging pile is in an available state from the beginning, so the first user can directly use the charging pile without any operation and can obtain a smooth use experience. In addition, since another idle charging pile is allocated to the second user, the use interest of the second user will not be affected. This method makes full use of the idle charging piles, improves the use experience of non-reserved users through the transfer between charging piles, does not affect the use interests of reserved users, and at the same time improves the overall efficiency.

[0009] According to a second aspect of the present disclosure, a charging pile reservation method is provided. The method includes: in response to a use request of a user who has reserved a first charging pile at a charging station for a second charging pile at the charging station, querying whether the second charging pile is in an idle state; if the second charging pile is in an idle state, canceling the reservation of the first charging pile by the user; and accepting the use request of the user for the second charging pile.

[0010] Through the second aspect of the present disclosure above, in the case where there are other idle charging piles at the charging station, after the reserved user arrives at the charging station, the reserved user can choose the desired idle charging pile to start charging, rather than forcing the user to drive to the reserved charging pile. This improves the use experience of the reserved user.

[0011] According to a third aspect of the present disclosure, a charging pile reservation device is provided. The device includes: a receiving module configured to receive a use request of a user for a charging pile; a query module configured to query the status of the charging pile, where the status includes in use, reserved, or idle; a notification module configured to notify the user of the request processing result; and a processing module coupled to the receiving module, the query module, and the notification module, and executing instructions to cause the charging pile reservation device to execute the method of the present disclosure.

[0012] According to a fourth aspect of the present disclosure, a charging pile reservation system is provided. The system includes a client, a server, and a charging pile. Among them, the client is configured to communicate with the server, receive a usage request for the charging pile from a user and forward it to the server, and receive a request processing result from the server and notify the user; the charging pile is configured to communicate with the server, send status information to the server, and receive and execute instructions related to vehicle charging from the server; the server is configured to execute instructions to enable the charging pile reservation system to execute the method of the present disclosure.

[0013] According to a fifth aspect of the present disclosure, a computer-readable storage medium is provided, on which a computer program is stored. When the computer program is executed by a processor, the method of the present disclosure is implemented.

[0014] Through the above third, fourth, and fifth aspects of the present disclosure, technical effects and advantages similar to those of the first and second aspects of the present disclosure can be obtained.

[0023] Next, the technical solutions of the present disclosure will be clearly and completely described in conjunction with the embodiments of the present disclosure and the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments, those skilled in the art can construct or obtain other embodiments without creative efforts. Therefore, the described embodiments are only exemplary and not restrictive.

[0024] It should be noted that the terms "first", "second", etc. in the specification, claims and above-mentioned drawings of the present disclosure are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0025] According to an embodiment of the present disclosure, there are provided a charging pile reservation method, a charging pile reservation device, a charging pile reservation system, and a computer-readable storage medium.

[0026] Figure 1 is a schematic diagram of a charging pile reservation system according to an embodiment of the present disclosure. As Figure 1 shown, the charging pile reservation system 100 includes a server 120, a client 110, and multiple charging piles 132, 134, 136, 142, 144, 146, etc. in charging stations 130 and 140. The server 120 is connected to the client 110 and each charging pile through a network. The network can include various connection types, such as wired, wireless communication links, or fiber optic cables, etc.

[0027] In an exemplary embodiment, the client 110 for data transmission with the server 120 may include, but is not limited to, types of electronic devices such as smart phones, desktop computers, tablet computers, laptop computers, digital assistants, AR (augmented reality) devices, VR (virtual reality) devices, smart wearable devices, etc. Optionally, the operating systems running on the electronic devices of the client 110 may include, but are not limited to, Android system, IOS system, linux, windows, etc. The client 110 has an interaction device, such as input and output devices such as a display screen or a microphone speaker. In the case where the display screen is used as the interaction device, requests such as requests for using the charging pile are received from the user through the program interface displayed on the display screen, and notifications are sent to the user through the program interface.

[0028] Server 120 can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, and big data and artificial intelligence platforms. Server 120 can be configured to execute instructions to enable the system to perform various corresponding operations and calculations, including the charging pile reservation method, etc.

[0029] Charging piles 132, 134, 136, 142, 144, 146, etc. are configured to communicate with server 120. Charging piles 132, 134, 136, 142, 144, 146, etc. can send status information to server 120. The status information includes the current charging status information, such as being in the process of charging, reserved, idle, etc. In the charging state, information such as the estimated charging percentage and the expected remaining charging time can also be sent. The status information can also include the charging gun temperature measured by the charging gun temperature sensors of charging piles 132, 134, 136, 142, 144, 146, etc., and the ambient temperature measured by the ambient temperature sensors. In addition, charging piles 132, 134, 136, 142, 144, 146, etc. can receive instructions from server 120 and perform operations related to vehicle charging, such as starting charging, ending charging, etc.

[0030] In addition, it should be noted that Figure 1 What is shown is only one embodiment of the charging pile reservation system provided by the present disclosure. Figure 1 The numbers of the client, server, and charging piles in [the figure] are only illustrative. According to actual needs, there can be any number of clients, servers, and charging piles.

[0031] Next, each step of the charging pile reservation method 200 of the present disclosure will be described in more detail in conjunction with the attached Figure 2A drawings.

[0032] In S201, in response to the use request of the first user for the first charging pile at the charging station, query whether the first charging pile is in a reserved state.

[0033] In an exemplary application scenario, the first user holding the first client comes to the charging station, parks the vehicle, picks up the charging gun of the first charging pile and inserts it into the vehicle, and sends a use request for charging with the first charging pile to the server through operations such as scanning the code with the first client and clicking on the program interface.

[0034] In another exemplary application scenario, a first user holding a first client sends a reservation request to the server to reserve a first charging pile by performing operations such as clicking on the program interface of the first client.

[0035] After receiving the usage request of the first charging pile in the charging station from the first user, the server queries the status of the first charging pile to confirm whether it is in a reserved state by another user (second user). This query can be implemented in various ways. As a non-limiting embodiment, the server can send a query request to the first charging pile and receive the response information returned by the charging pile. The status of the charging pile can include being in use, reserved, idle, etc. If the response information returned by the charging pile indicates that the charging pile is in use or idle, the server determines that the charging pile is not currently in a reserved state. If the response information returned by the first charging pile indicates that the first charging pile is in a state of being reserved by another user, the server determines that the first charging pile is currently in a reserved state by another user (second user). As another non-limiting embodiment, the server can store the status information of each charging pile. This status information is updated at a certain frequency. When querying, the server can retrieve the information stored to determine the status information of each charging pile.

[0036] In S202, if the first charging pile is in a reserved state by the second user, query whether there is an idle second charging pile in the charging station. When the first charging pile is in a reserved state by the second user, query the status of other charging piles in the charging station. This query can be carried out in the same way as in S201. As a result of the query, the query can end when an idle charging pile is found, and this idle charging pile is used as the idle second charging pile. Or, the status of all other charging piles in the charging station can be queried to obtain all idle charging piles. When there is at least one idle second charging pile, it is determined that there is an idle second charging pile among the charging piles.

[0037] In S203, if there is an idle second charging pile, change the reservation of the second user to the second charging pile. This change can be to shift the reservation content from the first charging pile to the second charging pile. The reservation content includes the reserved charging time period, etc. After the change, the changed content can be notified to the second user. The changed content includes at least the number of the second charging pile, etc., to facilitate the second user to quickly find the changed second charging pile when charging. When there are multiple idle charging piles, the charging pile closest to the first charging pile can be used as the second charging pile so that the impact on the reserved second user is minimized.

[0038] In S204, after changing the reservation of the second user to the idle second charging pile, the use request of the first user for the first charging pile is accepted. After the reservation of the second user is changed to the second charging pile, the first charging pile becomes idle, so the first user on site can use the first charging pile to charge.

[0039] The following will be combined with the attached Figure 2B to describe each step of the charging pile reservation method 200' of the present disclosure in more detail.

[0040] Figure 2B The flowchart of a charging pile reservation method 200' according to an embodiment of the present disclosure is shown. In Figure 2B the shown charging pile reservation method 200', S201' and S202' are similar to S201 and S202 of method 200 and will not be described in detail. In S203', if there is no idle second charging pile, the use request of the first user for the first charging pile is rejected and the first user is notified. By rejecting the first user, the use interests of the second user who has already made a reservation are guaranteed. In S204', the idle charging piles of other charging stations are recommended to the first user. By not only rejecting but also recommending the idle charging piles of other charging stations to the first user at the same time, the use experience of the first user can be improved. For example, the idle charging pile of the other charging station can be the nearest idle charging pile. The server determines the nearest idle charging pile of the other charging station in combination with the location information and status information of the charging pile.

[0041] Through the above charging pile reservation methods 200 and 200', even if the first charging pile has been reserved, in the case of an idle second charging pile, the reservation of the reserved user can be intelligently changed to the idle second charging pile. This change of reservation is shielded from the first user, or in other words, in this technical solution, the fact that the first charging pile is reserved and the reservation is changed to the second charging pile is not notified to the first user. Therefore, it seems to the first user that the first charging pile has been available from the beginning, so the charging pile can be directly used without any operation, and a smooth use experience can be obtained. In addition, since another idle charging pile is allocated to the second user, the use interests of the second user will not be affected. This method makes full use of the idle charging piles, improves the use experience of non-reserved users through the transfer between charging piles, does not affect the use interests of reserved users, and at the same time improves the overall efficiency.

[0042] The following will be combined with the attached Figure 3 to describe each step of another charging pile reservation method 300 of the present disclosure in more detail.

[0043] In S301, in response to a use request from a user of the first charging pile at a reserved charging station for the second charging pile at the charging station, query whether the second charging pile is in an idle state.

[0044] In an exemplary application scenario, a user who has reserved the first charging pile at a charging station inserts the charging gun of the second charging pile into the vehicle on-site to prepare for charging.

[0045] After receiving the use request from the reserved user for the second charging pile at the charging station, the server queries the status of the second charging pile to confirm whether it is in an idle state. This query can be implemented in various ways as described above for method 200 and will not be elaborated here.

[0046] In S302, if the second charging pile is in an idle state, cancel the user's reservation for the first charging pile. In S303, accept the user's use request for the second charging pile. When the second charging pile is in an idle state, that is, it is not being used or reserved by other users, then the user can be allowed to directly use the second charging pile without prompting the user that he has reserved the first charging pile. Additionally, when the second charging pile is not in an idle state, for example, when the second charging pile has been reserved by other users, reject the user's use of the second charging pile and notify the user that he has reserved the first charging pile. After seeing this notification, the user can move to the first charging pile for charging.

[0047] In the known prior art, if a user parks and charges at another charging pile after already reserving a charging pile, even if the charging pile is in an idle state, the system often prompts that the charging pile is not the one reserved by the user and prompts the user to move to the reserved charging pile. Compared with this prior art, the charging reservation method 300 of the present disclosure makes the charging process of reserved users smoother. For example, when there are idle charging piles at the charging station, the reserved user can choose a desired idle charging pile nearby to start charging after arriving at the charging station, instead of forcing the user to drive to the reserved charging pile. This improves the usage experience of reserved users to a certain extent.

[0048] The charging pile reservation methods 200 and 300 of the present disclosure make full use of the existence of idle charging piles to improve the usage experiences of both non-reserved users and reserved users.

[0049] Figure 4 It is a structural diagram of a charging pile reservation device according to an embodiment of the present disclosure. As Figure 4As shown, an embodiment of the present disclosure provides a charging pile reservation device 400. The charging pile reservation device 400 can be implemented by hardware, software, or a combination of hardware and software. The charging pile reservation device 400 can be communicatively coupled to a charging pile and / or a client. The charging pile reservation device 400 can be installed within a charging station, can be installed away from the charging station, or can be installed as software in an electronic device. The charging pile reservation device 400 includes a receiving module 404, a query module 406, a notification module 408, and a processing module 402.

[0050] The receiving module 404 is configured to receive a user's request for using a charging pile. The query module 406 is configured to query the status of the charging pile, where the status includes in use, reserved, or idle. The notification module 408 is configured to notify the user of the request processing result. The processing module 402 is coupled to the receiving module 404, the query module 406, and the notification module 408, and executes calculation instructions to cause the charging pile reservation device 400 to execute the method of the embodiment of the present disclosure.

[0051] Since the charging pile reservation device 400 executes calculation instructions to execute the method of the embodiment of the present disclosure, the charging pile reservation device 400 can also make full use of the existence of idle charging piles to improve the usage experience of both non-reserved users and reserved users.
