Description

Technical Field

[0001] This invention relates to the field of vehicle connectivity technology, and in particular to a method, apparatus, device, and medium for synchronizing information at charging stations. Background Technology

[0002] With the increasing popularity of electric vehicles, the construction and improvement of charging infrastructure has become crucial. Automotive OEMs' charging aggregation platforms need to connect to charging stations from numerous different manufacturers to provide users with a wide range of charging options. However, due to uncontrollable factors, such as charging station information push failures, some charging station companies may be unable to promptly notify the charging aggregation platform about the offline status of their charging stations. This can lead to users arriving at charging stations only to find they cannot charge normally, causing inconvenience and potentially impacting user trust in the brand.

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

[0004] While the charging aggregation function has been implemented, it lacks a management method for charging stations that need to be taken offline when data synchronization issues arise. Furthermore, it doesn't incorporate user habits into its early warning notifications for charging station shutdowns. Therefore, there is an urgent need for a method to enable autonomous monitoring and offline processing of charging stations. Additionally, sending offline notifications to potential users can prevent them from arriving at a station only to find it unavailable for charging, thereby improving user experience and trust in the charging platform. Summary of the Invention

[0005] The main purpose of this application is to provide a method, device, equipment and medium for synchronizing charging station information, aiming to solve the technical problem of how to realize the synchronous update of charging station information so as to provide users with early warning notifications.

[0006] To achieve the above objectives, this application proposes a method for synchronizing charging station information, the method comprising:

[0007] Obtain charging station configuration information;

[0008] When the charging station configuration information meets the preset offline conditions, the charging station status is set to offline status. The preset offline conditions are obtained from the charging station risk assessment and charging station management strategy.

[0009] The charging station status is sent to the cloud based on the charging station configuration information so that users within the preset offline notification range can simultaneously receive the charging station status.

[0010] In one embodiment, the step of setting the charging station status to offline when the charging station configuration information meets preset offline conditions includes:

[0011] The charging station usage conditions are obtained by comparing the charging station configuration information with the preset configuration parameters.

[0012] When the charging station meets the preset offline conditions, the charging station status is set to offline.

[0013] In one embodiment, the charging station configuration information includes the charging station enterprise code, the charging station offline date, the station range distance, and the station historical usage time threshold. The preset configuration parameters include the charging station offline date threshold, the detection cycle, the charging station offline notification station range, and the historical usage time threshold.

[0014] In one embodiment, the step of setting the charging station status to offline when the charging station's usage conditions meet preset offline conditions includes:

[0015] Based on the charging station's usage conditions, the latest usage date and frequency are obtained;

[0016] When the latest usage date exceeds the charging station's offline date threshold or the usage frequency exceeds the historical usage time threshold, the charging station's status will be set to offline.

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

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

[0019] The determination is made based on the distance, the user's usage time, and the charging station configuration to obtain the determination result.

[0020] When the determination result is that the distance is less than a preset distance, or when the determination result is that the distance is greater than a preset distance and the user's usage time is less than a preset time, the status of the charging station is sent to the cloud.

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

[0022] When the distance is greater than a preset distance and the user's 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 the updated distance and the updated time.

[0023] Based on the new distance and the new time, a warning notification is sent to users who meet the criteria.

[0024] In one embodiment, the step of adjusting the preset distance and the preset time according to a preset algorithm and a preset model to obtain the updated distance and the updated time includes:

[0025] The preset distance is adjusted using a weighted average algorithm to obtain the updated distance;

[0026] The preset time is updated by adjusting the parameters of the time series analysis model to obtain the updated time.

[0027] Furthermore, to achieve the above objectives, this application also proposes a charging station information synchronization device, which includes:

[0028] The acquisition module is used to acquire configuration information of multiple charging stations;

[0029] The judgment module is used to set the charging station status to offline status when the charging station configuration information meets the preset offline conditions. The preset offline conditions are obtained from the charging station risk assessment and the charging station management strategy.

[0030] The sending module is used to send the status of the charging station to the cloud according to the charging station configuration information, so that users within the preset offline notification range can simultaneously receive the charging station status.

[0031] In addition, to achieve the above objectives, this application also proposes a medium, which is a computer-readable medium, on which a computer program is stored, and which, when executed by a processor, implements the steps of the charging station information synchronization method described above.

[0032] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the charging station information synchronization method described above.

[0033] This application obtains charging station configuration information and sets the charging station status to offline when the configuration information meets preset offline conditions. These preset conditions are derived from charging station risk assessment and management strategies. Based on the charging station configuration information, the charging station status is sent to the cloud so that users within the preset offline notification range can simultaneously receive the charging station status. By dynamically assessing charging station risks, setting offline conditions according to management strategies, updating status, and synchronizing to the cloud, the accuracy of charging station information is improved, and the user experience is optimized.

[0039] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0041] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0042] The main solution of this application embodiment is: to obtain charging station configuration information, and when the charging station configuration information meets the preset offline conditions, to set the charging station status to offline status. The preset conditions are obtained by charging station risk assessment and 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 simultaneously obtain the charging station status.

[0043] Based on this, embodiments of this application provide a method for synchronizing charging station information, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the charging station information synchronization method of this application.

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

[0045] Step S10: Obtain charging station configuration information.

[0046] It's important to note that charging station configuration information includes the charging station company code, charging station offline date, station range distance, and historical usage time threshold. First, you need to configure the charging station company code table for scheduled monitoring, the charging station offline date threshold, and the detection cycle. By setting these parameters, the cloud system can periodically read the latest configuration file from the remote configuration repository and scan the charging station status accordingly. If a station does not receive updates from the charging station company within the set time, it is considered offline and removed from the list of available stations. Furthermore, regarding charging station offline (CSO) notifications after a charging station goes offline, you also need to set the station range distance (in kilometers) and the time threshold parameters for user usage of the station. These parameters can also be dynamically configured.

[0047] Step S20: When the charging station configuration information meets the preset offline conditions, the charging station status is set to offline status. The preset offline conditions are obtained from the charging station risk assessment and charging station management strategy.

[0048] It's important to note that when a charging station's configuration information meets preset offline conditions, its status will be set to offline. These preset offline conditions are jointly determined by the charging station's risk assessment and management strategy. The risk assessment analyzes the charging station's usage history and current status to evaluate its operational risks and determine whether offline measures are necessary to prevent users from arriving to find their devices unavailable for charging. The management strategy, based on the charging station's configuration information and risk assessment results, formulates corresponding management policies, including when a charging station should be taken offline and how to notify users. For example, if no updated information about the charging station is received from the charging station provider within a certain period, this may be a signal that the charging station has ceased service. In this case, the charging station is considered risky and needs to be taken offline to prevent users from going to unavailable stations based on outdated information. In such situations, the charging aggregation platform will decide whether to set the charging station's status to offline based on pre-set rules, such as a charging station offline date threshold (e.g., if set to 3 days, it means that if no updated information is received from the charging station provider within 3 days, the station is considered offline).

[0049] Furthermore, the charging station usage conditions are determined by comparing the charging station configuration information with preset configuration parameters. The cloud system reads preset configuration parameters from the remote configuration database based on parameters such as the charging station enterprise code table monitored periodically, the charging station offline date threshold, and the detection cycle. These preset configuration parameters include the charging station offline date threshold, the detection cycle, the range of charging station offline notification sites, and the historical usage time threshold. The system then periodically scans the status of charging stations based on these configuration parameters. For example, if the preset charging station offline date threshold is 3 days, the cloud system will check if any sites have not received charging station enterprise push notifications for more than 3 days and mark these sites as offline. In addition, the cloud system will periodically perform this check according to the detection cycle to ensure the real-time nature of the information.

[0050] Furthermore, when the usage conditions of a charging station meet the preset offline conditions, the charging station's status is set to offline. This process relies on a cloud-based dynamic configuration system. The system periodically reads the latest configuration files from a remote configuration database. The cloud periodically scans the status of charging stations based on parameters such as the charging station company code table, charging station offline date thresholds, and detection cycles. If a station does not receive updated information from the charging station company within a predetermined time, the station is considered to have met the offline conditions, and the system automatically removes the station from the list of available stations and sets it to offline. In addition, the system sets CSO notification parameters, including station range distance and user usage time threshold parameters, all of which are dynamically configured. The cloud adjusts these parameters based on vehicle charging information and user preferences to ensure the accuracy of notifications. For example, if a user frequently charges at a specific charging station, their app will receive a notification that the station is offline, allowing the user to plan their charging in advance and avoid arriving to find that charging is unavailable.

[0051] Specifically, the system obtains the latest usage date and frequency based on the charging station's usage conditions. During the determination of these conditions, the system evaluates the station's status based on data such as the latest usage date and frequency. The latest usage date refers to the last time a user was recorded using the charging station, while the usage frequency refers to the number of times the charging station has been used within a given period. These two metrics are crucial for determining whether a charging station remains active. If a charging station's latest usage date is very distant and its usage frequency is low, the station is likely no longer frequently used and may even be offline. The charging station is set to offline status when the latest usage date exceeds a charging station offline date threshold or the usage frequency exceeds a historical usage time threshold. This means that if a charging station has no new usage records within a preset time period, or its usage frequency significantly decreases, the system will determine that the station may have ceased operation or is no longer suitable for continued use.

[0052] Step S30: Send the charging station status to the cloud according to the charging station configuration information so that users within the preset offline notification range can simultaneously receive the charging station status.

[0053] It's important to understand that if a charging station meets the offline criteria, it will be removed from the list of available stations and marked as offline. Simultaneously, the system will send a warning notification via the brand's app to all users whose location or charging habits meet the criteria, informing them that the charging station is offline and preventing situations where users arrive only to find they cannot charge.

[0054] This embodiment provides a method for synchronizing charging station information. It obtains charging station configuration information and, when the configuration information meets preset offline conditions, sets the charging station status to offline. These preset conditions are derived from charging station risk assessment and management strategies. The charging station status is then sent to the cloud based on the configuration information, ensuring that users within the preset offline notification range are simultaneously notified of the charging station status. By dynamically assessing charging station risks, setting offline conditions according to management strategies, updating the status, and synchronizing it to the cloud, the accuracy of charging station information is improved, and the user experience is optimized.

[0055] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 The charging station information synchronization method step S30 further includes steps S301 to S303:

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

[0057] It's important to note that the cloud can calculate the distance between the vehicle and the target charging station in real time using the vehicle's GPS data, serving as a key reference for deciding whether to send a warning notification to the user. If a user's frequently used charging station suddenly goes offline, and the user is located relatively close to that charging station, the system will prioritize sending a notification to that user.

[0058] Meanwhile, the cloud also records the user's charging history, including the time of each charge. By analyzing the user's charging habits, it is possible to determine the timing patterns of the user's use of specific charging stations. If it is found that a user tends to use a certain charging station during a specific time period, and that charging station happens to be offline, the system will combine distance and time factors to promptly send a warning message to the user via the brand's app that the charging station is offline.

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

[0060] It's important to understand that the system comprehensively assesses factors such as the distance between the charging station and the user, the user's usage time, and the charging station's configuration information to determine whether to set the charging station's status to offline and send a warning notification to the user. First, the system obtains the distance information between the vehicle and the charging station. If a user frequently visits a charging station that is close to their current location, that user will be included in the target user group for warning notifications. Second, the system analyzes the user's charging history to identify which charging station the user most frequently uses, and when and where. If it finds that the user has fixed charging time and location preferences, the system will prioritize sending warning notifications to these users when the status of these charging stations changes.

[0061] In addition, the system will also evaluate the status of charging stations based on their configuration information, such as the offline date threshold and detection cycle. If a charging station has not updated its information for an extended period of time, or if its status does not meet the preset usage conditions, the system will determine that the charging station has been taken offline and will send a notification through the brand's app to nearby users with similar usage time preferences, informing them that the charging station has been taken offline and preventing them from going to stations that cannot be used for charging.

[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's usage time is less than the preset time, the charging station status is sent to the cloud.

[0063] It's important to understand that when the distance to a charging station is less than a preset distance, or the distance is greater than a preset distance but the user's usage time is less than a preset time, the system will send the charging station's status to the cloud for further processing. Specifically, when the user's current location is less than a preset distance from a charging station, it means the user is likely to choose that station. In this case, even if the charging station's status is not explicitly marked as offline, the system will still send its status information to the cloud to confirm its availability. If the charging station has been marked as a potentially offline station, the system will send a warning notification to the user, reminding them that the station may not be usable. On the other hand, if the user's current location is greater than a preset distance from the charging station and the user's usage time is less than a preset time, the system will also send the charging station's status information to the cloud. In this case, even if the user is not currently near the charging station, because the user has frequently used the station in the past, the system will still send a warning notification to the user through the brand's app, informing them that the charging station may be offline, preventing the user from choosing an unavailable station when planning to charge in the future.

[0064] Furthermore, when the distance exceeds a preset distance and the user's usage time exceeds a preset time, the preset distance and time are adjusted according to a preset algorithm and model to obtain updated distance and time. Based on the updated distance and time, a warning notification is sent to users who meet the criteria. When a user's current location is greater than the preset distance to a charging station, and the user's usage time also exceeds the preset time, the cloud system adjusts the preset distance and time according to a preset algorithm and model to obtain updated distance and time parameters. The preset algorithm is based on a time series analysis model, considering the user's historical charging behavior, travel patterns, and other relevant factors to dynamically adjust the distance and time thresholds. For example, if a 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 over a wider area. Simultaneously, the preset time is also adjusted accordingly to ensure that the notification is closer to the user's actual charging needs. After adjustment, the system reassesses the user's charging station usage conditions based on the updated distance and time parameters. If the new distance and time parameters indicate that the user may still need the charging station, the system will send a warning notification to users who meet the criteria, reminding them of the charging station's status change and avoiding future inconvenience.

[0065] Specifically, the preset distance is adjusted using a weighted average algorithm to obtain the updated distance. The system uses a weighted average algorithm to calculate a new distance threshold based on the user's last driving distance before reaching the charging station in the most recent few instances. The specific formula is as follows:

[0066]

[0067] The vehicle-side system will calculate the final distance the user's vehicle traveled to the charging station using x. i The records reported to the cloud platform, N is the number of data points included in the weighted average calculation, and y i This represents the weighted value of the calculated data, where the result 'a' is the unweighted average of N data points. Specifically, the cloud collects the user's driving distance data before reaching a charging station several times and assigns a weight value to each data point. The weight value reflects the degree of influence of that driving distance on the calculation result. For example, the most recent driving distance might be given a higher weight, while earlier driving distances might be given a lower weight. Through weighted averaging, the cloud can obtain an updated distance threshold that better reflects the user's actual travel patterns.

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

[0069]

[0070] Where μ0, ∈0, T is the model fitting parameter. t-i This sets time thresholds for the i time points in the configuration sequence. When user habits change, such as when a user starts charging at different times or changes the charging frequency, the cloud system captures these changes and adjusts these parameters by retraining the model. The adjusted parameters enable the model to more accurately reflect the user's current behavior patterns, thereby updating the preset time thresholds.

[0071] This embodiment obtains the distance between the vehicle and the charging station and the user's usage time. Based on the distance, user usage time and charging station configuration, a judgment is made to obtain the judgment result. 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's usage time is less than the preset time, the charging station status is sent to the cloud. The charging station status is updated and synchronized to the cloud by making judgments, thereby optimizing the user experience.
