[0002] With the increasing popularity of electric vehicles, the construction and improvement of charging infrastructure has become crucial. The charging aggregation platform of automobile OEMs needs to access charging piles from many different manufacturers to provide users with a wide range of charging options. However, due to uncontrollable factors, such as charging pile information push failures, some charging pile companies may not be able to promptly notify the charging aggregation platform about the offline status of charging stations, resulting in users arriving at the charging station and finding that they cannot charge normally. This not only brings inconvenience to users, but may also affect users' trust in the brand.

[0003] At present, through the community charging aggregation platform, which includes access module, management module, application module, security module and transaction module, it can effectively aggregate various charging objects and services within the community, improving management efficiency and resource utilization.

[0004] Although the charging aggregation function has been realized, the management method of the sites that need to be offline when the data synchronization of the charging station of the charging company is problematic has not been considered; at the same time, there is no early warning notification of the offline charging station based on the user's usage habits. Therefore, there is an urgent need for a method to realize the autonomous monitoring and offline processing of charging stations, and to send offline charging station notifications to potential users to avoid the situation where users find that they cannot charge after arriving at the station, thereby improving the user experience and trust in the charging platform. Summary of the invention

[0015] According to the charging station usage conditions, the latest usage date and usage frequency are obtained;

[0016] When the latest usage date exceeds a charging station offline date threshold or the usage frequency exceeds a historical usage time threshold, the charging station status is set to an offline status.

[0017] In one embodiment, the step of sending the charging station status to the cloud according to the charging station configuration information includes:

[0018] Obtain the distance between the vehicle and the charging station and the user's usage time;

[0019] Making a judgment based on the distance, the user usage time and the configuration of the charging station to obtain a judgment result;

[0020] When the judgment result is that the distance is less than the preset distance or the judgment result is that the distance is greater than the preset distance and the user usage time is less than the preset time, the charging station status is sent to the cloud.

[0021] In one embodiment, when the judgment result is that the distance is less than a preset distance or the judgment result is that the distance is greater than a preset distance and the user usage time is less than a preset time, the step of sending the charging station status to the cloud further includes:

[0022] When the distance is greater than a preset distance and the user usage time is greater than a preset time, the preset distance and the preset time are adjusted according to a preset algorithm and a preset model to obtain an updated distance and an updated time;

[0040] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0041] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0042] The main solution of the embodiment of the present application is: obtaining the charging station configuration information, and when the charging station configuration information meets the preset offline conditions, setting the charging station status to the offline status, the preset conditions are obtained by the charging station risk assessment and the charging station management strategy, and the charging station status is sent to the cloud according to the charging station configuration information, so that users who meet the preset offline notification range can obtain the charging station status synchronously.

[0043] Based on this, the embodiment of the present application provides a charging station information synchronization method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the charging station information synchronization method of the present application.

[0044] In this embodiment, the charging station information synchronization method includes steps S10 to S30:

[0045] Step S10, obtaining charging station configuration information.

[0046] It should be noted that the charging station configuration information includes the pile company code, the date of the charging station going offline, the site range distance and the site historical usage time threshold. First, it is necessary to configure the pile company code table for timed monitoring, the date threshold for the charging station going offline, and the detection cycle. By setting these parameters, the cloud system can regularly read the latest configuration files from the remote configuration warehouse and scan and check the status of the charging site accordingly. If it is found that a site has not received any update information from the pile company within the set time, the site is considered to be offline and will be removed from the list of available sites. In addition, for the charging site offline (CSO) notification after the charging station goes offline, it is also necessary to set the site range distance (in kilometers) and the time threshold parameters for users to use the site. These parameters can also be dynamically configured.

[0047] Step S20: When the charging station configuration information meets the preset offline condition, the charging station state is set to an offline state, and the preset offline condition is obtained by the charging station risk assessment and the charging station management strategy.

[0048] It should be noted that when the configuration information of the charging station meets the preset offline conditions, the status of the charging station will be set to the offline state. These preset offline conditions are jointly determined by the risk assessment and management strategy of the charging station. The risk assessment of the charging station analyzes the usage history and current status of the charging station, evaluates its operating risk, and determines whether offline measures need to be taken to prevent users from finding that they cannot charge after arriving. The management strategy is to formulate corresponding management strategies based on the configuration information of the charging station and the risk assessment results, including when the charging station should be offline and how to notify users. For example, if no update information about the charging station is received from the charging pile company within a certain period of time, this may be a signal that the charging station has stopped service. At this time, the charging station is considered to be at risk and needs to be offline to avoid users going to a station that cannot charge based on outdated information. In this case, the charging aggregation platform will decide whether to set the status of the charging station to offline based on pre-set rules, such as the charging station offline date threshold (if set to 3 days, it means that if no update information is received from the charging pile company within 3 days, the station is considered to be offline).

[0049] Furthermore, the charging station usage conditions are obtained by comparing the charging station configuration information with the preset configuration parameters. The charging station usage conditions are obtained by comparing the charging station configuration information with the preset configuration parameters. The cloud system will read the preset configuration parameters from the remote configuration database based on the pile enterprise coding table for timed monitoring, the charging station offline date threshold, the detection cycle and other parameters. The preset configuration parameters include the charging station offline date threshold, the detection cycle, the charging station offline notification site range and the historical usage time threshold. And regularly scan the status of the charging site according to these configuration parameters. For example, if the preset charging station offline date threshold is 3 days, the cloud system will check whether there are sites that have not received the information pushed by the pile enterprise for more than 3 days, and mark these sites as offline. In addition, the cloud will also perform this inspection operation regularly according to the detection cycle to ensure the real-time nature of the information.

[0050] Further, when the use conditions of the charging station meet the preset offline conditions, the status of the charging station is set to the offline state. When the use conditions of the charging station meet the preset offline conditions, the status of the charging station is set to the offline state. This process relies on the cloud dynamic configuration system. By regularly reading the latest configuration files from the remote configuration database, the cloud regularly scans the status of the charging station according to the pile enterprise coding table, the charging station offline date threshold, the detection cycle and other parameters monitored by the timer. If it is found that a site has not received the update information from the pile enterprise within the predetermined time, the site is deemed to meet the offline conditions, and then the system will automatically remove the site from the list of available sites and set it to the offline state. In addition, the system also sets CSO notification parameters, including the site range distance and the time threshold parameters for the user to use the station, which are dynamically configured. The cloud will adjust these parameters according to the vehicle charging information and the user's usage preferences to ensure the accuracy of the notification. For example, if a user often charges at a specific charging station, the user's APP will receive a notification that the site has been offline, so that the user can plan the charging plan in advance to avoid the situation where it is impossible to charge after arriving.

[0051] Specifically, according to the use conditions of the charging station, the latest use date and the use frequency are obtained. In the process of determining the use conditions of the charging station, the system will evaluate the status of the station based on data such as the latest use date and the use frequency of the charging station. The latest use date refers to the time when the charging station was last recorded as being used by a user, and the use frequency refers to the number of times the charging station was used within a period of time. These two indicators are crucial for determining whether the charging station is still active. If the latest use date of a charging station is very far away from now and the use frequency is very low, then the station is likely no longer frequently used and may even be offline. When the latest use date exceeds the offline date threshold of the charging station or the use frequency exceeds the historical use time threshold, the charging station status is set to the offline state. When the latest use date of the charging station exceeds the preset offline date threshold of the charging station, or the use frequency is lower than the historical use time threshold, the cloud system will set the status of the charging station to the offline state. This means that if a charging station has no new use records within a preset time period, or its use frequency drops significantly, the system will determine that the station may have stopped operating or is no longer suitable for continued use.

[0052] Step S30, sending the charging station status to the cloud according to the charging station configuration information, so that users who meet the preset offline notification range can obtain the charging station status synchronously.

[0053] It is important to understand that if a station is found to meet the offline conditions, it will be removed from the list of available stations and set to offline status. At the same time, the system will send an early warning notification through the brand APP to all users whose distance or usage habits meet the conditions based on the user's location information and historical charging habits, informing the user that the charging station has been offline to avoid the situation where the user finds that he cannot charge after arriving.

[0054] This embodiment provides a charging station information synchronization method, which obtains the charging station configuration information, and sets the charging station status to the offline status when the charging station configuration information meets the preset offline conditions. The preset conditions are obtained by the charging station risk assessment and the charging station management strategy. The charging station status is sent to the cloud according to the charging station configuration information, so that users who meet the preset offline notification range can obtain the charging station status synchronously. By dynamically assessing the risk of the charging station, setting the offline conditions according to the management strategy, updating the status and synchronizing it to the cloud, the accuracy of the charging station information is improved, and the user experience is optimized.

[0055] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 The charging station information synchronization method step S30 also includes steps S301 to S303:

[0056] Step S301, obtaining the distance between the vehicle and the charging station and the user's usage time.

[0057] It should be noted that the cloud can calculate the distance between the vehicle and the target charging station in real time through the vehicle's GPS data, which serves as one of the important references for whether to send a warning notification to the user. If a user's frequently used charging station is suddenly offline and the user is located close to the charging station, the system will give priority to sending a notification to the user.

[0058] At the same time, the cloud will also record the user's charging history, including the time of each charging. By analyzing the user's charging habits, it is possible to derive the time pattern of the user's use of a specific charging station. If it is found that the user tends to use a charging station during a specific time period, and the charging station happens to be offline, the system will combine distance and time factors to send the user a warning message of the charging station being offline in a timely manner through the brand APP.

[0059] Step S302, making a judgment based on the distance, user usage time and charging station configuration to obtain a judgment result.

[0060] It is important to understand that the system will make a comprehensive judgment based on the distance between the charging station and the user, the user's usage time, and the configuration information of the charging station to decide whether to set the status of the charging station to offline and send an early warning notification to the user. First, the system will obtain the distance information between the vehicle and the charging station. If the charging station that the user frequently visits is close to his current location, then the user will be included in the target user group for the early warning notification. Secondly, the system will analyze the user's charging history and identify which charging station the user most frequently uses and when. If it is found that the user has a fixed charging time and location preference, then when the status of these charging stations changes, the system will give priority to sending early warning notifications to these users.

[0061] In addition, the system will evaluate the status of the charging station based on the configuration information of the charging station, such as the offline date threshold of the charging station, the detection cycle and other parameters. If the charging station has not updated information for a long time, or its status does not meet the preset usage conditions, the system will determine that the charging station has been offline, and send a notification to users who are close to the charging station and have similar usage time preferences through the brand APP, informing them that the charging station has been offline, so as to avoid users going to a station that cannot be charged.

[0062] Step S303, when the judgment result is that the distance is less than the preset distance or the judgment result is that the distance is greater than the preset distance and the user usage time is less than the preset time, the charging station status is sent to the cloud.

[0063] It should be understood that when the judgment result is that the distance is less than the preset distance or the distance is greater than the preset distance but the user's use time is less than the preset time, the system will send the status of the charging station to the cloud for further processing. Specifically, when the distance between the user's current location and a charging station is less than the preset distance, it means that the user is likely to choose the charging station for charging. At this time, even if the status of the charging station has not been clearly displayed as offline, the system will send its status information to the cloud to confirm its availability. If the charging station has been marked as a potential offline site, the system will send an early warning notification to the user to remind the user that the site may not be used normally. On the other hand, if the distance between the user's current location and the charging station is greater than the preset distance and the user's use time is less than the preset time, the system will also send the status information of the charging station to the cloud. In this case, even if the user is not currently near the charging station, because the user has frequently used the site in the past, the system will still send an early warning notification to the user through the brand APP to inform him that the charging station may have been offline, so as to avoid the user from choosing an unavailable site when planning to charge in the future.

[0064] Further, when the distance is greater than the preset distance and the user's use time is greater than the preset time, the preset distance and preset time are adjusted according to the preset algorithm and preset model to obtain the updated distance and updated time; according to the new distance and updated time, a judgment is made, and an early warning notification is sent to the user who meets the conditions. When the user's current location is greater than the preset distance from the charging station, and the user's use time also exceeds the preset time, the cloud system will adjust the preset distance and preset time according to the preset algorithm and model to obtain the updated distance and time parameters. The preset algorithm is based on the time series analysis model, considering the user's historical charging behavior, travel mode and other relevant factors, and dynamically adjusts the distance and time thresholds. For example, if the user's charging frequency is low and the travel distance is large, the preset distance may be appropriately increased to search for potentially available charging stations in a larger range. At the same time, the preset time will also be adjusted accordingly to ensure that the notification is closer to the user's actual charging needs. After the adjustment, the system will re-evaluate the user's charging station usage conditions based on the updated distance and time parameters. If the new distance parameter and time parameter indicate that the user may still need the charging station, the system will send an early warning notification to the user who meets the conditions to remind them of the change in the status of the charging station to avoid future inconvenience.

[0065] Specifically, the preset distance is adjusted through a weighted average algorithm to obtain an updated distance. The system will use a weighted average algorithm to calculate a new distance threshold based on the last driving distance before the user arrived at the charging station several times recently. The specific formula is:

[0066]

[0067] The vehicle side will record the last distance x of the user's vehicle to the charging station. i Report to the cloud platform for record, N is the number of data included in the weighted average calculation, y i Represents the weighted value of the calculated data, and the calculation result a is the unweighted average of N data. Specifically, the cloud will collect the user's driving distance data before arriving at the charging station for the last few times, and assign a weight value to each data point. The weight value reflects the degree of influence of the driving distance on the calculation result. For example, the most recent driving distance may be assigned a higher weight, while the earlier driving distance is assigned a lower weight. Through weighted average calculation, the cloud can obtain an updated distance threshold, which is more in line with the user's actual travel mode.

[0068] By adjusting the parameters of the time series analysis model to update the preset time, the updated time is obtained. The parameters of the time series analysis model include fitting parameters, which are determined through model training. The specific formula is:

[0069]

[0070] Among them, μ0,∈0, is the model fitting parameter, T t-i is the time threshold for the i-th time point in the configuration sequence. When the user's usage habits change, for example, the user starts charging at different time periods or the charging frequency changes, the cloud system will capture these changes and adjust these parameters by retraining the model. The adjusted parameters enable the model to more accurately reflect the user's current behavior pattern, thereby updating the preset time threshold.

[0071] This embodiment obtains the distance between the vehicle and the charging station and the user's usage time, and makes a judgment based on the distance, user's usage time and charging station configuration to obtain a judgment result. When the judgment result is that the distance is less than a preset distance or the judgment result is that the distance is greater than a preset distance and the user's usage time is less than a preset time, the charging station status is sent to the cloud. By making a judgment, the charging station status is updated and synchronized to the cloud, thereby optimizing the user experience.

[0072] This application also provides a charging station information synchronization device, please refer to Figure 3 , the device comprises:

[0073] The acquisition module 10 is used to acquire multiple charging station configuration information.

[0074] The judgment module 20 is used to set the charging station status to an offline state when the charging station configuration information meets a preset offline condition, and the preset condition is obtained by the charging station risk assessment and the charging station management strategy.

[0075] The sending module 30 is used to send the charging station status to the cloud according to the charging station configuration information, so that users who meet the preset offline notification range can obtain the charging station status synchronously.
