Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a control method for plug-and-charge charging piles. Background Technology

[0002] With the booming development of the new energy vehicle market and the continuous increase in the number of vehicles, photovoltaic-storage charging stations are being widely used. Existing photovoltaic-storage charging stations require users to log into an account on a mobile application to ensure sufficient balance. Users then select the charging amount and initiate charging within the application. Upon receiving the charging request, the cloud platform sends a charging command to the energy management system of the photovoltaic-storage charging station, enabling the energy management system to control the charging pile to charge the vehicle.

[0003] However, the inventors discovered that when a photovoltaic (PV) and energy storage charging station experiences a network failure, it cannot communicate with the cloud platform. This prevents the charging station from receiving charging commands from the cloud platform, affecting its normal operation. Due to the large number of PV and energy storage charging stations, maintenance personnel may not be able to promptly identify and troubleshoot stations with network failures, leading to low reliability. Furthermore, while some vehicles can sign cooperation agreements for free charging or monthly billing, existing PV and energy storage charging stations still require requests from partner vehicles to charge. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a control method for plug-and-charge charging piles, so as to solve the problems that the current photovoltaic and energy storage charging stations cannot operate normally when the network is disconnected, that maintenance personnel may not be able to troubleshoot network faults of photovoltaic and energy storage charging stations in a timely manner during the operation and maintenance process, and that the charging operation is cumbersome.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a control method for plug-and-charge charging piles, comprising the following steps:

[0006] S1: The cloud platform generates and manages the online identification code information table. The cloud platform periodically synchronizes the online identification code information table to the energy management system so that the energy management system stores the local identification code information table, and the cloud platform records the synchronization time.

[0007] S2: The energy management system obtains the vehicle identification code of the vehicle through the charging pile and determines whether the energy management system is connected to the network; if so, the cloud platform verifies the vehicle identification code according to the online identification code information table, and the cloud platform controls the charging pile to charge the vehicle; if not, the energy management system verifies the vehicle identification code according to the local identification code information table, and the energy management system controls the charging pile to charge the vehicle.

[0008] S3: When the time difference between the synchronization time and the current time exceeds the preset synchronization time range, the cloud platform generates a warning message.

[0009] Furthermore, the local identification code information table includes the receiving time and the valid time range.

[0010] Furthermore, in step S2, the energy management system verifies the vehicle identification code according to the local identification code information table, including:

[0011] The energy management system determines whether the time difference between the received time and the current time exceeds the valid time range; if so, the energy management system controls the charging pile not to charge the vehicle; if not, the energy management system verifies the vehicle identification code according to the local identification code information table.

[0012] Furthermore, in step S2, the cloud platform controls the charging pile to charge the vehicle, including:

[0013] The system determines whether the cloud platform has successfully verified the vehicle verification code. If so, the cloud platform generates an online charging order and sends a start charging command to the energy management system. The energy management system then sends a charging command to the charging pile according to the start charging command, so that the charging pile can charge the vehicle. If not, the cloud platform sends a verification failure message to the energy management system.

[0014] Furthermore, in step S2, the energy management system controls the charging pile to charge the vehicle, including:

[0015] The system determines whether the energy management system verifies the vehicle identification code. If yes, the energy management system generates an offline charging order and sends a charging command to the charging pile, which then charges the vehicle. If no, the energy management system controls the charging pile not to charge the vehicle.

[0016] Furthermore, it also includes: when the energy management system recovers from a disconnected state to a connected state, the energy management system sends the offline charging order to the cloud platform.

[0017] Furthermore, it also includes: when the energy management system recovers from a disconnected state to a connected state, the energy management system sends an update request to the cloud platform, and the cloud platform synchronizes the identification code information table to the energy management system of the charging station according to the update request.

[0018] Furthermore, in step S2, the energy management system obtains the vehicle identification number (VIN) of the vehicle through the charging pile, including: when the charging pile is connected to the charging port of the vehicle, the charging pile initiates an interaction request to the vehicle, and the charging pile obtains the interaction message of the vehicle to obtain the vehicle identification number.

[0019] Furthermore, in step S1, the cloud platform records the synchronization time, including:

[0020] Determine whether the cloud platform successfully synchronized the online identification code information table to the energy management system; if yes, the cloud platform records the synchronization time; if no, the cloud platform does not record the synchronization time.

[0021] Furthermore, in step S3, when the time difference between the synchronization time and the current time exceeds a preset synchronization time range, the cloud platform generates a warning message, including:

[0022] The cloud platform periodically checks the online identification code information table and determines whether the time difference between the synchronization time and the current time exceeds the preset synchronization time range; if so, the cloud platform generates and pushes a warning message; if not, the cloud platform waits for the next synchronization.

[0023] The beneficial effects of this invention are as follows: The control method provided by this invention simplifies the charging process. When a user's vehicle signs a relevant cooperation agreement, the cloud platform imports the vehicle identification code (VIC) of the cooperating vehicle into the VIC information table of the cloud platform. When the vehicle connects to the charging pile of the charging station, the charging pile obtains the vehicle's VIC. The cloud platform or energy management system verifies the VIC according to the VIC information table. When the VIC passes verification, the charging pile can be controlled to charge the vehicle, thereby realizing the plug-and-charge function of the charging pile. This control method is convenient and quick, eliminating the need for cumbersome operations by the user. In addition, in this control scheme, the cloud platform can periodically synchronize the VIC information table to the energy management system. Therefore, when the energy management system is offline, it can verify the vehicle VIC based on its locally stored VIC information table, thus solving the problem of the charging station not being able to operate normally when there is a network failure. Furthermore, this control method can also record the successful synchronization time of the VIC information table as the synchronization time. When the time difference between the synchronization time and the current time exceeds the preset synchronization time range, the cloud platform can generate a warning message to notify the maintenance personnel to check the network problem of the relevant charging station, thereby improving the reliability of the charging station.

[0025] Figure 2This is a flowchart of step S2 of the control method according to an embodiment of the present invention. Detailed Implementation

[0026] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] Please refer to Figure 1 as well as Figure 2 This invention provides a control method for plug-and-charge charging piles, which includes the following steps:

[0028] S1: The cloud platform generates and manages the online identification code information table. The cloud platform periodically synchronizes the online identification code information table to the energy management system so that the energy management system stores the local identification code information table, and the cloud platform records the synchronization time.

[0029] S2: The energy management system obtains the vehicle identification code of the vehicle through the charging pile and determines whether the energy management system is connected to the network; if so, the cloud platform verifies the vehicle identification code according to the online identification code information table, and the cloud platform controls the charging pile to charge the vehicle; if not, the energy management system verifies the vehicle identification code according to the local identification code information table, and the energy management system controls the charging pile to charge the vehicle.

[0030] S3: When the time difference between the synchronization time and the current time exceeds the preset synchronization time range, the cloud platform generates a warning message.

[0031] As described above, the beneficial effects of this invention are as follows: The control method provided by this invention simplifies the charging process. When a user's vehicle signs a relevant cooperation agreement, the cloud platform imports the vehicle identification code (VIC) of the cooperating vehicle into the online VIC information table of the cloud platform. When the vehicle connects to the charging pile of the charging station, the charging pile obtains the vehicle's VIC. The cloud platform or energy management system verifies the VIC according to the VIC information table. When the VIC passes verification, the charging pile can be controlled to charge the vehicle, thereby realizing the plug-and-charge function of the charging pile. This control method is convenient and quick, eliminating the need for cumbersome operations by the user. In addition, in this control scheme, the cloud platform can periodically synchronize the VIC information table to the energy management system. Therefore, when the energy management system is offline, it can verify the vehicle VIC based on its locally stored VIC information table, thus solving the problem of the charging station not being able to operate normally when there is a network failure. Furthermore, this control method can also record the synchronization time of the successful synchronization of the VIC information table. When the time difference between the synchronization time and the current time exceeds a preset synchronization time range, the cloud platform can generate a warning message to notify maintenance personnel to check the network problem of the relevant charging station, thereby improving the reliability of the charging station.

[0032] Furthermore, the local identification code information table includes the receiving time and the valid time range.

[0033] Furthermore, in step S2, the energy management system verifies the vehicle identification code according to the local identification code information table, including:

[0034] The energy management system determines whether the time difference between the received time and the current time exceeds the valid time range; if so, the energy management system controls the charging pile not to charge the vehicle; if not, the energy management system verifies the vehicle identification code according to the local identification code information table.

[0035] As described above, the local identification code information table in this control method is valid within a preset effective time range. Once the local identification code information table exceeds the effective time range, it is discarded, thus ensuring the timeliness and reliability of the local identification code information table. The effective time range can be configured on the cloud platform. When the cloud platform synchronizes the online identification code information table to the energy management system, the effective time range is also synchronized to the local identification code information table accordingly.

[0036] Furthermore, in step S2, the cloud platform controls the charging pile to charge the vehicle, including:

[0037] The system determines whether the cloud platform has successfully verified the vehicle verification code. If so, the cloud platform generates an online charging order and sends a start charging command to the energy management system. The energy management system then sends a charging command to the charging pile according to the start charging command, so that the charging pile can charge the vehicle. If not, the cloud platform sends a verification failure message to the energy management system.

[0038] As described above, since the online identification code information table of the cloud platform is updated in real time, the reliability of verifying the vehicle identification code through the cloud platform is higher when the energy management system is connected to the network. This can avoid the problem of unsuccessful vehicle identification code verification due to the local identification code information table not being updated.

[0039] Furthermore, in step S2, the energy management system controls the charging pile to charge the vehicle, including:

[0040] The system determines whether the energy management system verifies the vehicle identification code. If yes, the energy management system generates an offline charging order and sends a charging command to the charging pile, which then charges the vehicle. If no, the energy management system controls the charging pile not to charge the vehicle.

[0041] As described above, when the vehicle identification number can be verified by the local identification number information table stored locally in the energy management system, the energy management system can control the charging pile to charge the vehicle in the offline state and generate a corresponding offline charging order to record the vehicle information and the charging pile charging parameter information.

[0042] Furthermore, it also includes: when the energy management system recovers from a disconnected state to a connected state, the energy management system sends the offline charging order to the cloud platform.

[0043] As described above, the energy management system reports offline charging orders generated during the network outage to the cloud platform so that the cloud platform can settle or compile statistics on the orders.

[0044] Furthermore, it also includes: when the energy management system recovers from a disconnected state to a connected state, the energy management system sends an update request to the cloud platform, and the cloud platform synchronizes the online identification code information table to the energy management system according to the update request.

[0045] As described above, the cloud platform synchronizes the online identification code information table to the energy management system according to the update request, so that the energy management system can update the local identification code information table, thereby ensuring the reliability of the local identification code information table.

[0046] Further, in step S2, the energy management system obtains the vehicle identification number (VIN) of the vehicle through the charging pile, including: when the charging pile is connected to the charging port of the vehicle, the charging pile initiates an interaction request to the vehicle, and the charging pile obtains the interaction message of the vehicle to obtain the vehicle identification number.

[0047] As described above, when a user plugs the charging plug of the charging pile into the charging port of the vehicle, the charging station control system using this control method can automatically complete the process of obtaining the vehicle identification code, verification, and startup. This control method is convenient and fast.

[0048] Furthermore, in step S1, the cloud platform records the synchronization time, including:

[0049] Determine whether the cloud platform successfully synchronized the online identification code information table to the energy management system; if yes, the cloud platform records the synchronization time; if no, the cloud platform does not record the synchronization time.

[0050] As described above, this control method records the synchronization time only when the cloud platform and the energy management system are successfully synchronized. Therefore, it can identify whether the energy management system of the charging station has been offline for a long time based on the synchronization time. When the energy management system is offline for a long time, the cloud platform can send a warning message to the operation and maintenance personnel to notify them to check the network problem of the charging station.

[0051] Furthermore, in step S3, when the time difference between the synchronization time and the current time exceeds a preset synchronization time range, the cloud platform generates a warning message, including:

[0052] The cloud platform periodically checks the online identification code information table and determines whether the time difference between the synchronization time and the current time exceeds the preset synchronization time range; if so, the cloud platform generates and pushes a warning message; if not, the cloud platform waits for the next synchronization and ends the process.

[0053] As described above, the cloud platform periodically checks the online identification code information table to ensure the accuracy of the information. Additionally, the cloud platform records the time of the last successful synchronization, designating this as the synchronization time. Since the cloud platform records the synchronization time after successful synchronization in both periodic synchronization and when the energy management system requests an update to restore network connectivity, using the synchronization time and its range to determine whether the energy management system has been in a prolonged network outage is highly reliable.

[0054] This invention provides a plug-and-charge control method for charging piles. This control method is applicable to charging station control systems. Applying this control method can ensure that the charging station can at least charge cooperative vehicles normally when the network is disconnected, and eliminates the cumbersome login verification operation for users. The following is a description of specific implementation methods.

[0055] Example 1

[0056] Please refer to Figures 1 to 2 Embodiment 1 of the present invention provides a control method for plug-and-charge charging piles, the control method comprising the following steps:

[0057] S1: The cloud platform generates and manages the online identification code information table. The cloud platform periodically synchronizes the online identification code information table to the energy management system so that the energy management system stores the local identification code information table, and the cloud platform records the synchronization time.

[0058] S2: The energy management system obtains the vehicle identification code of the vehicle through the charging pile and determines whether the energy management system is connected to the network; if so, the cloud platform verifies the vehicle identification code according to the online identification code information table, and the cloud platform controls the charging pile to charge the vehicle; if not, the energy management system verifies the vehicle identification code according to the local identification code information table, and the energy management system controls the charging pile to charge the vehicle.

[0059] S3: When the time difference between the synchronization time and the current time exceeds the preset synchronization time range, the cloud platform generates a warning message.

[0060] In step S1 of this embodiment, when a user's vehicle signs a relevant cooperation agreement, the cloud platform imports the vehicle identification code of the cooperating vehicle into the cloud platform's online identification code information table.

[0061] In this embodiment, the local identification code information table includes the receiving time and the valid time range.

[0062] When the energy management system is connected to the network, the cloud platform will periodically synchronize the online identification code information table to the energy management system of the charging station through the IoT gateway. At the same time, the cloud platform will also configure the effective time (in hours) of the online identification code information table after it is synchronized to the energy management system of the charging station. That is, during synchronization, the energy management system records the effective time range of the local identification code information table according to the effective time configured by the cloud platform. In addition, the energy management system records the time when it receives the online identification code information table as the reception time.

[0063] Therefore, in step S2, the energy management system verifies the vehicle identification code according to the local identification code information table, including: the energy management system determining whether the time difference between the received time and the current time exceeds the valid time range; if yes, the energy management system controls the charging pile not to charge the vehicle; if no, the energy management system verifies the vehicle identification code according to the local identification code information table.

[0064] Please refer to Figure 2 In step S2 of this embodiment, the energy management system controls the charging pile to charge the vehicle, including:

[0065] The system determines whether the energy management system verifies the vehicle identification code. If yes, the energy management system generates an offline charging order and sends a charging command to the charging pile, which then charges the vehicle. If no, the energy management system controls the charging pile not to charge the vehicle.

[0066] In detail, in step S2, when the energy management system is in a state of network disconnection, the energy management system verifies the validity of the local identification code information table based on the reception time and the valid time range, so as to improve the credibility of the local identification code information table. This can prevent the charging station from using an expired local identification code information table to verify the vehicle identification code after being in a state of network disconnection for a long time.

[0067] When the energy management system determines that the time difference between the received time and the current time exceeds the valid time range, the local identification code information table expires. That is, the local identification code information table stored by the energy management system at the current time is invalid, and the energy management system cannot verify the vehicle identification code based on the invalid local identification code information table.

[0068] When the energy management system is offline, if the local identification code information table stored in the energy management system is within its validity period, the energy management system compares the local identification code information table with the vehicle identification code. If the vehicle identification code passes the verification of the local identification code information table, the charging pile can charge the vehicle. At the same time, the energy management system can generate a corresponding offline charging order to record the vehicle information and the charging pile's charging parameters.

[0069] Preferably, when the energy management system is offline, if the local identification code information table is invalid or the vehicle identification code verification fails, the energy management system can send an invalid command to the charging pile so that the charging pile notifies the user that the current charging station cannot charge the vehicle.

[0070] When the energy management system recovers from a disconnected state to a connected state, the energy management system sends an update request to the cloud platform. The cloud platform synchronizes the identification code information table to the energy management system of the charging station according to the update request, and the energy management system sends the offline charging order to the cloud platform.

[0071] The cloud platform synchronizes the online identification code information table to the energy management system based on update requests, enabling the energy management system to update its local identification code information table and thus ensuring its reliability. The energy management system reports offline charging orders generated during network outages to the cloud platform for order settlement and statistics.

[0072] In step S2 of this embodiment, the cloud platform controls the charging pile to charge the vehicle, including:

[0073] The system determines whether the cloud platform has successfully verified the vehicle verification code. If so, the cloud platform generates an online charging order and sends a start charging command to the energy management system. The energy management system then sends a charging command to the charging pile according to the start charging command, so that the charging pile can charge the vehicle. If not, the cloud platform sends a verification failure message to the energy management system.

[0074] In detail, when the energy management system is connected to the network, it sends the acquired vehicle identification number (VIN) to the cloud platform via an IoT gateway. The cloud platform compares the VIN with the online VIN information table to verify the VIN. When the VIN verification is successful, the cloud platform sends a charging start command to the charging station's energy management system via the IoT gateway. The energy management system then sends a charging pile command to the charging pile, which charges the vehicle according to the charging pile command. When the VIN verification fails, the energy management system sends a login guidance command to the charging pile. The charging pile's interactive system guides the user through the login and verification process based on the login guidance command.

[0075] In step S2 of this embodiment, the energy management system obtains the vehicle identification code of the vehicle through the charging pile, including: when the charging pile is connected to the charging port of the vehicle, the charging pile initiates an interaction request to the vehicle, and the charging pile obtains the interaction message of the vehicle to obtain the vehicle identification code.

[0076] In detail, when a user needs to use a charging station to charge their vehicle, they will plug the charging station into the vehicle's charging port. At this time, when the charging station is connected to the vehicle's charging port, the charging station automatically initiates interaction with the vehicle. Specifically, the charging station and the vehicle communicate with each other through interaction messages. The charging station can obtain the vehicle's interaction messages to obtain the vehicle identification number, and then the charging station sends the vehicle identification number to the energy management system.

[0077] In step S1 of this embodiment, the cloud platform records the synchronization time, including:

[0078] Determine whether the cloud platform successfully synchronized the online identification code information table to the energy management system; if yes, the cloud platform records the synchronization time; if no, the cloud platform does not record the synchronization time.

[0079] In step S3 of this embodiment, when the time difference between the synchronization time and the current time exceeds a preset synchronization time range, the cloud platform generates a warning message, including:

[0080] The cloud platform periodically checks the online identification code information table and determines whether the time difference between the synchronization time and the current time exceeds the preset synchronization time range; if so, the cloud platform generates and pushes a warning message; if not, the cloud platform waits for the next synchronization.

[0081] Specifically, the cloud platform records the time of the last successful synchronization with the energy management system and marks this time as the synchronization time. The cloud platform also periodically checks the online identification code information table to ensure its validity and accuracy.

[0082] Since the cloud platform records the synchronization time for both periodic synchronization and when the energy management system requests an update to restore network connectivity, the synchronization time and its range can be used to determine if the energy management system has been offline for an extended period. When the energy management system is offline for too long, the cloud platform generates a warning message and pushes it to maintenance personnel via SMS, email, etc., allowing them to intervene promptly and investigate network issues at the charging station. If the charging station is offline, on-site personnel are notified to investigate the network problem; if synchronization is not enabled or fails, cloud platform technicians are notified to investigate.

[0083] In summary, the control method provided by this invention simplifies the charging process. When a user's vehicle signs a relevant cooperation agreement, the cloud platform imports the vehicle identification number (VIN) of the cooperating vehicle into the cloud platform's online VIN information table. When the vehicle connects to the charging pile of the charging station, the charging pile obtains the vehicle's VIN. The cloud platform or energy management system verifies the VIN according to the VIN information table. When the VIN is verified, the charging pile can be controlled to charge the vehicle, thus realizing the plug-and-charge function of the charging pile. This control method is convenient and quick, requiring no cumbersome operation from the user. Furthermore, this control scheme... The cloud platform can periodically synchronize the identification code information table to the energy management system. Therefore, when the energy management system is offline, it can verify the vehicle identification code based on the locally stored identification code information table, thus solving the problem of charging stations not being able to operate normally when there is a network failure. In addition, this control method can also record the time information of the successful synchronization of the identification code information table to the energy management system online as the synchronization time. When the time difference between the synchronization time and the current time exceeds the preset synchronization time range, the cloud platform can generate a warning message to notify the operation and maintenance personnel to check the network problem of the relevant charging station, thereby improving the reliability of the charging station.

[0084] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
