Description

Technical Field

[0001] The present application relates to the technical field of charging pile control, and particularly to a charging pile control method, system, medium and product with load control. Background Art

[0002] With the rapid development and popularization of the electric vehicle industry, charging piles, as an important infrastructure for electric vehicle charging, are also expanding in scale. At the same time, the large-scale application of charging piles has brought huge load pressure and energy management problems to the power system. The use of charging piles is also often affected by various factors such as users' work and living habits. Therefore, the charging demand of electric vehicles is uncertain and unpredictable. In addition, the load characteristics of charging piles are different from those of traditional electrical equipment. The load during the use of charging piles has large power fluctuations and peak-valley differences. When a large number of charging piles are in the working state at the same time, it will pose a severe test to the stability and power supply capacity of the power system.

[0003] In related technologies, the load of charging piles is generally adjusted based on manual experience or fixed rules. However, the load management of charging piles usually needs to comprehensively consider factors such as the real-time state of the power system, users' charging demands, and the availability of charging facilities. When using manual experience to regulate the load of charging piles, the regulation accuracy may be relatively low, which may pose a threat to the safety of equipment such as the power grid system and charging piles. Summary of the Invention

[0004] In order to improve the accuracy of regulating the load of charging piles, the present application provides a charging pile control method, system, medium and product with load control.

[0005] In a first aspect, the present application provides a charging pile control method with load control, adopting the following technical solutions:

[0006] A charging pile control method with load control includes:

[0007] Obtaining the screen limit power value of the charging pile to be regulated based on the current moment, where the screen limit power value is determined according to historical power consumption data, and the historical power consumption data includes the historical power values of each charging pile within a historical time period;

[0009] Identify the regulation network port number corresponding to the charging pile to be regulated, obtain the operation data of the regulation network port corresponding to the charging pile to be regulated based on the regulation network port number, and determine the operation limit power value of the charging pile to be regulated based on the operation data of the regulation network port;

[0010] Compare the screen limit power value, the EMS limit power value, and the operation limit power value to determine the target limit power value, and regulate the charging pile to be regulated based on the target limit power value.

[0011] By adopting the above technical solution, by analyzing the historical power values of each charging pile in the historical time period, it is convenient to more accurately predict and set the screen limit power value of the current charging pile to be regulated. In addition, by analyzing the regulation serial port communication data corresponding to the charging pile to be regulated and the operation data of the regulation network port corresponding to the charging pile to be regulated, the EMS limit power value corresponding to the regulation serial port and the operation limit power value corresponding to the regulation network port are respectively determined. The multi-dimensional consideration method is convenient for more comprehensively predicting the appropriate power limit value of the charging pile to be regulated, that is, the multi-dimensional consideration method is convenient for improving the accuracy when determining the power regulation of the charging pile to be regulated, and thus is also convenient for improving the stability and safety of devices such as the charging pile to be regulated and the power grid system.

[0012] In a possible implementation manner, the comparing the screen limit power value, the EMS limit power value, and the operation limit power value to determine the target limit power value includes:

[0013] Obtain the actual working power, and determine the timing duration corresponding to the charging pile to be regulated based on the timing mapping relationship and the actual working power. The timing mapping relationship is the corresponding relationship between the actual working power and the timing duration corresponding to the charging pile to be regulated;

[0014] Obtain the current time, and judge whether the timing ends based on the current time and the timing duration. If so, judge whether the screen limit power value is less than the operation limit power value;

[0015] If the screen limit power value is less than the operation limit power value, judge whether the screen limit power value is less than the EMS limit power value. If so, determine the screen limit power value as the target limit power value. If not, determine the EMS limit power value as the target limit power value;

[0016] If the screen limit power value is not less than the operation limit power value, judge whether the operation limit power value is less than the EMS limit power value. If so, determine the operation limit power value as the target limit power value. If not, determine the EMS limit power value as the target limit power value.

[0017] By adopting the above technical solutions, the embodiments of the present application provide a method for determining a target power limit value from the screen power limit value, the EMS power limit value, and the operation power limit value, and determining the minimum power limit value as the target power limit value to facilitate reducing the pressure on the power grid caused by the actual charging power, and also facilitating ensuring the safety and compliance of the entire charging process while meeting the charging needs of users.

[0018] In a possible implementation manner, the determining the EMS power limit value of the to-be-regulated charging pile based on the regulated serial port communication data includes:

[0019] Writing the regulated serial port communication data into a first preset circular buffer, and identifying the communication features included in the regulated serial port communication data;

[0020] Based on the communication features and the first preset protocol mapping relationship, determining a first parsing protocol corresponding to the communication features, where the first preset protocol mapping relationship is the corresponding relationship between the communication features and the first parsing protocol;

[0021] Parsing the regulated serial port communication data based on the first parsing protocol to obtain the EMS power limit value of the to-be-regulated charging pile.

[0022] By adopting the above technical solutions, by writing the regulated serial port communication data into the circular buffer, it is convenient to temporarily store and orderly process the regulated serial port communication data. In addition, writing the regulated serial port communication data into the circular buffer can effectively solve the delay problem of the regulated serial port communication data during the transmission process, ensuring that the regulated serial port communication data will not be lost due to untimely processing speed. By determining the corresponding parsing protocol through the communication features and parsing the regulated serial port communication data based on the parsing protocol, it is convenient to improve the flexibility when obtaining communication data. In addition, it also helps to improve the accuracy when determining the EMS power limit value.

[0023] In a possible implementation manner, the determining the operation power limit value of the to-be-regulated charging pile based on the regulated network port operation data includes:

[0024] Writing the regulated network port operation data into a second preset circular buffer, and identifying the operation features included in the regulated network port operation data;

[0025] Based on the operation features and the second preset protocol mapping relationship, determining a second parsing protocol corresponding to the communication features, where the preset protocol mapping relationship is the corresponding relationship between the communication features and the second parsing protocol;

[0026] Parsing the regulated network port operation data based on the second parsing protocol to obtain the operation power limit value of the to-be-regulated charging pile.

[0027] By adopting the above technical solution, writing the regulated network port operation data into the circular buffer facilitates the temporary storage and orderly processing of the regulated network port operation data. In addition, writing the regulated network port operation data into the circular buffer can effectively solve the delay problem of the regulated network port operation data during the transmission process, ensuring that the regulated network port operation data will not be lost due to untimely processing speed. Determine the corresponding parsing protocol based on the operation characteristics, and parse the regulated network port operation data based on the parsing protocol, which facilitates improving the flexibility when obtaining operation data. In addition, it also helps to improve the accuracy when determining the operation limit power value.

[0028] In a possible implementation manner, when the target limit power value is the EMS limit power value or the operation limit power value, it further includes:

[0029] Obtain the usage device parameters and charging records, where the usage device parameters are the standard power range corresponding to the device using the to-be-regulated charging pile for charging;

[0030] When the target limit power value exceeds the standard power range, determine the duration required for charging completion according to the charging records;

[0031] Obtain the operation parameters of the to-be-regulated charging pile, and simulate the operation situation of the to-be-regulated charging pile within a first preset time period based on the operation parameters and the device parameters to obtain simulated operation data. The first preset time period is a predicted duration after the current moment, where the predicted duration is the same as the duration required for charging completion;

[0032] Identify the simulated power value included in the simulated operation data. When the simulated power value is within the preset limit range and the duration required for charging completion is lower than the preset limit duration, regulate the to-be-regulated charging pile based on the target limit power value within a second preset time period.

[0033] By adopting the above technical solution, after determining the appropriate target limit power value of the to-be-regulated charging pile, instead of directly regulating the to-be-regulated charging pile based on the target limit power, it is judged whether the replacement of the target limit power value of the to-be-regulated charging pile will affect the charging device based on the parameters of the charging device in use and the charging records. If the replacement of the power limit value may affect the device being charged, the possible anomalies are evaluated according to the operation simulation results, and then it is determined whether it is necessary to regulate the to-be-regulated charging pile based on the evaluation results. If the risk level corresponding to the evaluation result is low, the to-be-regulated charging pile can be regulated after the charging device finishes charging. In addition, by adding the feature of the preset limit duration, it is possible to ensure the safety of the charging pile during the charging process while facilitating the improvement of the safety and stability of the charging pile.

[0034] In a possible implementation manner, when the simulated power value exceeds the preset limit range, or the duration required for charging completion is not less than the preset limit duration, it further includes:

[0035] Determine at least one associated charging pile of the to-be-regulated charging pile based on the regulation network port number, and each associated charging pile has the same regulation network port number as the to-be-regulated charging pile;

[0036] Obtain the associated usage records of each associated charging pile, and determine the power margin corresponding to each associated charging pile based on each associated usage record, and determine the associated charging pile with the highest power margin as the target associated charging pile;

[0037] Determine the power difference according to the actual usage power value of the to-be-regulated charging pile and the corresponding target limit power value, and determine the associated limit power value of the target associated charging pile based on the power difference.

[0038] By adopting the above technical solution, if the risk level corresponding to the evaluation result is relatively high, the load pressure on the power grid can be alleviated by reducing the power limit value of the associated charging pile of the to-be-regulated charging pile, so as to facilitate ensuring the safety and stability of the to-be-regulated charging pile, the power grid, and the charging equipment during the charging of the charging equipment. In addition, regulating the target associated charging pile based on the power difference is convenient for improving the regulation rate and regulation accuracy.

[0046] In a fourth aspect, the present application provides a computer program product, adopting the following technical solution:

[0047] A computer program product includes a computer program which, when executed by a processor, implements the above-mentioned charging pile control method with load control.

[0048] In summary, the present application includes at least one of the following beneficial technical effects:

[0049] By analyzing the historical power values of each charging pile within a historical time period, it is convenient to more accurately predict and set the screen limit power value of the currently to-be-regulated charging pile. In addition, by analyzing the regulation serial port communication data corresponding to the to-be-regulated charging pile and the operation data of the regulation network port corresponding to the to-be-regulated charging pile, the EMS limit power value corresponding to the regulation serial port and the operation limit power value corresponding to the regulation network port are respectively determined. Through a multi-dimensional consideration method, it is convenient to more comprehensively predict the appropriate power limit value of the to-be-regulated charging pile, that is, through a multi-dimensional consideration method, it is convenient to improve the accuracy when determining the power regulation of the to-be-regulated charging pile, thereby also facilitating the improvement of the stability and safety of devices such as the to-be-regulated charging pile and the power grid system.

[0050] After determining the appropriate target limit power value of the to-be-regulated charging pile, instead of directly regulating the to-be-regulated charging pile based on the target limit power, it is judged whether changing the target limit power value of the to-be-regulated charging pile will affect the charging device based on the parameters of the charging device in use and the charging record. If changing the power limit value may affect the device being charged, the possible anomalies are evaluated according to the operation simulation results, and then it is determined whether it is necessary to regulate the to-be-regulated charging pile based on the evaluation results. If the risk level corresponding to the evaluation result is low, the to-be-regulated charging pile can be regulated after the charging device finishes charging. In addition, by adding the feature of a preset limit duration, it is possible to ensure the safety of the charging pile during the charging process while also facilitating the improvement of the safety and stability of the charging pile.

[0055] The following further describes the present application in detail Figures 1-4 with reference to the attached drawings.

[0056] After reading this specification, those skilled in the art may make modifications to this embodiment that do not contribute creatively as needed, but as long as they are within the scope of the claims of this application, they are protected by the patent law.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this application.

[0058] It should be noted that in the alternative embodiments of this application, for relevant data such as object information, when the embodiments in this application are applied to specific products or technologies, object permission or consent is required, and the collection, use, and processing of relevant data need to comply with the relevant laws, regulations, and standards of relevant countries and regions. That is to say, if the embodiments in this application involve data related to an object, it needs to be obtained with the authorization and consent of the object, the authorization and consent of relevant departments, and compliance with the relevant laws, regulations, and standards of the country and region. In the embodiments, if personal information is involved, the acquisition of all personal information requires the consent of the individual. If sensitive information is involved, the separate consent of the information subject is required, and the embodiments also need to be implemented with the authorization and consent of the object.

[0059] Specifically, the embodiments of this application provide a charging pile control method with load control, which is executed by a control system. The control system can be a server or a terminal device. Among them, the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected through wired or wireless communication methods, and this application does not make any restrictions in this regard.

[0060] Refer to Figure 1 , Figure 1 is a schematic flowchart of a charging pile control method with load control in the embodiments of this application. The method includes steps S110 - S140, where:

[0061] Step S110: Based on the current moment, obtain the screen limit power value of the charging pile to be regulated. The screen limit power value is determined according to historical power consumption data, and the historical power consumption data includes the historical power values of each charging pile within a historical time period.

[0062] Specifically, the charging piles to be regulated generally display their power limits intuitively through a display screen to remind relevant users to select appropriate charging piles for charging. The screen power limits corresponding to different types of charging piles to be regulated are different. For example, when the type of the charging pile to be regulated is the slow charging type, the corresponding screen power limit may be 3.3 kilowatts or 7 kilowatts; when the type of the charging pile to be regulated is the fast charging type, the corresponding screen power limit may be above 60 kilowatts. Among them, the slow charging type of charging pile to be regulated may be suitable for long-term charging scenarios such as homes, while the fast charging type of charging pile to be regulated may be suitable for places that require fast charging such as highway service areas and shopping malls.

[0063] The screen power limit value of the charging pile to be regulated can be determined according to historical power consumption data. Among them, the historical power consumption data contains the charging records of each charging pile to be regulated within a historical time period, including the start time, end time, charging amount, and charging power value of each charge, which can be obtained from the background management system of the charging pile to be regulated. In addition, the compliance data of the power grid in each charging stage needs to be collected to analyze the carrying capacity and fluctuation of the power grid. Finally, the demand for the charging power value by users in different time periods can be analyzed. For example, in the peak charging period, a higher power value may be required to meet the demand for fast charging, while in the low charging period, the power value can be reduced to save power grid resources. Based on the analysis results, the screen power limit value corresponding to the charging pile to be regulated in different time periods is determined. The screen power limit value corresponding to the charging pile to be regulated in any time period needs to meet the charging needs of users and cannot cause too much load pressure on the power grid. For example, according to the historical power consumption data, there are two power values that can meet the charging needs of users in a certain xx time period, namely power value a and power value b. Among them, when the power value a or power value b is used as the power limit value in the historical xx time period and the load pressure on the power grid is lower than the preset pressure threshold, the power value a or power value b can be determined as the screen power limit value corresponding to the charging pile to be regulated in the xx time period; when the power value a is used as the power limit value in the historical xx time period and the load pressure on the power grid is lower than the preset pressure threshold, and when the power value b is used as the power limit value in the historical xx time period and the compliance pressure on the power grid is not lower than the preset pressure threshold, the power value a can be determined as the screen power limit value corresponding to the charging pile to be regulated in the xx time period.

[0064] Step S120: Identify the control serial port number corresponding to the charging pile to be regulated, obtain the control serial port communication data corresponding to the charging pile to be regulated based on the control serial port number, and determine the EMS power limit value of the charging pile to be regulated based on the control serial port communication data.

[0065] Specifically, each charging pile to be regulated corresponds to a regulation serial port number. Through the regulation serial port number corresponding to the charging pile to be regulated, the actual power consumption values of all devices belonging to the same regulation serial port number can be received. Among them, in addition to receiving the actual power consumption value of the corresponding charging pile to be regulated, the same regulation serial port number can also receive the actual power consumption values of other devices. Other devices may include environmental monitoring devices, safety protection devices, and auxiliary devices. The environmental monitoring devices are used to monitor the temperature, humidity, air quality, etc. around the charging pile to be regulated to ensure safety during the charging process. The safety protection devices may include overcurrent protectors, leakage protectors, lightning protection devices, etc., for the safety of the charging equipment. The auxiliary devices may be display screens, card readers, etc., for providing information interaction functions for users.

[0066] The regulation serial port communication data contains the actual power consumption values of the charging piles to be regulated and other devices. Since each regulation serial port corresponds to a regulation power limit value, that is, when the total actual power limit value of all electrical devices corresponding to the regulation serial port during use is not higher than the regulation power limit value, the load pressure on the power grid is relatively low. Therefore, all electrical devices corresponding to the same regulation serial port need to allocate power values based on the regulation power limit value, and the EMS limit power value of the charging pile to be regulated is obtained after the power value allocation. Since the electrical devices corresponding to different regulation serial ports are different, the power value allocation methods displayed by the regulation power limits corresponding to different regulation serial ports are different.

[0067] Furthermore, in order to improve the accuracy when determining the EMS limit power value, the EMS limit power value of the charging pile to be regulated is determined based on the regulation serial port communication data. Specifically, it may include:

[0068] Write the regulation serial port communication data into the first preset circular buffer, and identify the communication characteristics included in the regulation serial port communication data; based on the communication characteristics and the first preset protocol mapping relationship, determine the first parsing protocol corresponding to the communication characteristics. The first preset protocol mapping relationship is the corresponding relationship between the communication characteristics and the first parsing protocol; based on the first parsing protocol, parse the regulation serial port communication data to obtain the EMS limit power value of the charging pile to be regulated.

[0069] Specifically, the first preset circular buffer can be a circular buffer pool for storing regulated serial communication data. Using a circular buffer pool to store regulated serial communication data facilitates the effective management of storage space, thus facilitating data overflow. In addition, writing the regulated serial communication data into the circular buffer can effectively solve the delay problem of the regulated serial communication data during transmission, ensuring that the regulated serial communication data will not be lost due to untimely processing speed. Since different chargers to be regulated or other devices belonging to the same regulated serial port as the charger to be regulated may have different manufacturers, the data forms of the regulated serial communication data corresponding to different chargers to be regulated or other devices belonging to the same regulated serial port as the charger to be regulated may be different. Based on the communication characteristics included in different regulated serial communication data, it is convenient to quickly locate the first parsing protocol corresponding to the regulated serial communication data. Different communication characteristics correspond to different first parsing protocols. According to the first preset protocol mapping relationship, the first parsing protocol corresponding to any communication characteristic can be determined. The first preset protocol mapping relationship can be determined by relevant staff based on historical experimental data and then uploaded to the control system. The specific content is not specifically limited in the embodiments of the present application.

[0070] After determining the first parsing protocol corresponding to the regulated serial communication data, the regulated serial communication data is parsed based on the first parsing protocol to obtain regulated parsing data. Based on the above method, the regulated parsing data corresponding to each of the charger to be regulated and other devices belonging to the same regulated serial port as the charger to be regulated can be determined. The power value allocation method of the regulated power display corresponding to the regulated serial port is stored in the corresponding regulated parsing data. By performing feature recognition on the regulated parsing data of the charger to be regulated, the EMS limit power value corresponding to the charger to be regulated can be determined.

[0071] Step S130: Identify the regulated network port number corresponding to the charger to be regulated, obtain the regulated network port operation data corresponding to the charger to be regulated based on the regulated network port number, and determine the operation limit power value of the charger to be regulated based on the regulated network port operation data.

[0072] Specifically, a regulation network port can receive the regulation network port operation data corresponding to multiple chargers to be regulated. For the convenience of management, generally, a factory area or a parking lot is divided into multiple areas, each area corresponds to a regulation network port, and a regulation operation power limit value is set for each regulation network port. All chargers to be regulated belonging to the same regulation network port need to allocate power values based on the regulation operation power limit value. The operation limit power value of the charger to be regulated is obtained after power value allocation. Since the types and performances of different chargers to be regulated are different, the operation limit power values corresponding to different chargers to be regulated within the same regulation network port are different. The regulation network port numbers corresponding to each charger to be regulated are different. Based on the regulation network port number, the regulation network port operation data corresponding to the charger to be regulated can be accurately determined from multiple regulation network port operation data. By performing feature recognition on the regulation network port operation data, the operation limit power value corresponding to the charger to be regulated can be determined.

[0073] Further, in order to improve the accuracy when determining the operation limit power value, determining the operation limit power value of the charger to be regulated based on the regulation network port operation data may specifically include:

[0074] Write the regulation network port operation data into the second preset circular buffer, and identify the operation features included in the regulation network port operation data; based on the operation features and the second preset protocol mapping relationship, determine the second parsing protocol corresponding to the communication features. The preset protocol mapping relationship is the corresponding relationship between the communication features and the second parsing protocol; parse the regulation network port operation data based on the second parsing protocol to obtain the operation limit power value of the charger to be regulated.

[0075] Specifically, the second preset circular buffer is the same as the first preset circular buffer and is a circular buffer pool. By writing the regulation network port operation data into the second preset circular buffer, not only can the regulation network port operation data be stored orderly, but also the situation of packet overflow during the transmission of the regulation network port operation data can be reduced, thereby facilitating the improvement of the integrity of the regulation network port operation data. Since the manufacturers corresponding to different chargers to be regulated are different, the data forms of the regulation network port operation data corresponding to different chargers to be regulated may be different. Based on the operation features included in different regulation network port operation data, it is convenient to quickly locate the second parsing protocol corresponding to the regulation network port operation data. Different operation features correspond to different second parsing protocols. According to the second preset protocol mapping relationship, the second parsing protocol corresponding to any operation feature can be determined. The second preset protocol mapping relationship can be determined by relevant staff based on historical experimental data and then uploaded to the control system. The specific content is not specifically limited in the embodiments of the present application.

[0076] Step S140: Compare the screen power limit value, the EMS power limit value, and the operation power limit value to determine the target power limit value, and regulate the charging pile to be regulated based on the target power limit value.

[0077] Specifically, after determining the screen power limit value, the EMS power limit value, and the operation power limit value of the charging pile to be regulated, the corresponding power limit values of the three can be directly compared to determine the target power limit value. The target power limit value can be the minimum value. The embodiments of the present application provide a method for determining the target power limit value from the screen power limit value, the EMS power limit value, and the operation power limit value of the charging pile to be regulated, which may specifically include:

[0078] Obtain the actual working power, and determine the timing duration corresponding to the charging pile to be regulated based on the timing mapping relationship and the actual working power. The timing mapping relationship is the corresponding relationship between the actual working power and the timing duration corresponding to the charging pile to be regulated.

[0079] Specifically, the actual working power is the working power corresponding to the charging pile to be regulated at the current moment. Different actual working powers correspond to different timing durations. The greater the actual working power, the shorter the corresponding timing duration. The timing mapping relationship includes the timing durations corresponding to different actual working powers. A period of timing duration represents a judgment cycle. After the judgment cycle ends, it is necessary to re-determine the target power limit value from the screen power limit value, the EMS power limit value, and the operation power limit value. For example, according to the actual working power corresponding to charging pile a, the timing duration corresponding to charging pile a is determined to be 500 milliseconds.

[0080] Obtain the current moment, and judge whether the timing has ended based on the current moment and the timing duration. If so, judge whether the screen power limit value is less than the operation power limit value; if the screen power limit value is less than the operation power limit value, then judge whether the screen power limit value is less than the EMS power limit value. If so, determine the screen power limit value as the target power limit value. If not, determine the EMS power limit value as the target power limit value; if the screen power limit value is not less than the operation power limit value, then judge whether the operation power limit value is less than the EMS power limit value. If so, determine the operation power limit value as the target power limit value. If not, determine the EMS power limit value as the target power limit value.

[0081] Before each judgment, it is necessary to first judge whether the current moment has ended the timing. Only after the timing ends will the power limit value comparison link be started. As Figure 2 shown, Figure 2This is a judgment process flow chart provided by an embodiment of the present application. The judgment process flow chart includes multiple judgment execution process lines. If the timing corresponding to the current moment has not ended, it can be directly executed to the end node. If the timing corresponding to the current moment has ended, the screen power limit value can be compared with the EMS power limit value first, or the screen power limit value can be compared with the operation power limit value first. The sequence of comparison among the three is not specifically limited in the embodiment of the present application. As Figure 2 shown Figure 2 in the figure, first compare the screen power limit value with the operation power limit value. When the screen power limit value is less than the operation power limit value, then compare the smaller screen power limit value of the two with the EMS power limit value. If the screen power limit value is still less than the EMS power limit value, directly determine the screen power limit value as the target power limit value. And so on, for the specific execution process of other judgment execution process lines in the judgment process flow chart, reference can be made to the execution method of the judgment execution process line for determining the screen power limit value as the target power limit value, which will not be elaborated here.

[0082] For the embodiment of the present application, by analyzing the historical power values of each charging pile in the historical time period, it is convenient to more accurately predict and set the screen power limit value of the currently to-be-regulated charging pile. In addition, by analyzing the regulation serial port communication data corresponding to the to-be-regulated charging pile and the regulation network port operation data corresponding to the to-be-regulated charging pile, the EMS power limit value corresponding to the regulation serial port and the operation power limit value corresponding to the regulation network port are respectively determined. The multi-dimensional consideration method is convenient for more comprehensively predicting the appropriate power limit value of the to-be-regulated charging pile, that is, the multi-dimensional consideration method is convenient for improving the accuracy when determining the power regulation of the to-be-regulated charging pile, thereby also facilitating the improvement of the stability and safety of equipment such as the to-be-regulated charging pile and the power grid system.

[0083] Furthermore, in order to facilitate the improvement of the safety and stability of the charging pile, the method provided by the embodiment of the present application further includes steps S1 - S4, as Figure 3 shown, where:

[0084] Step S1: Obtain the device usage parameters and charging records. The device usage parameters are the standard power range of the device corresponding to charging with the to-be-regulated charging pile.

[0085] Specifically, the device parameters are for the devices that are using the charging pile to be regulated for charging, including but not limited to electric vehicles, electric motorcycles, and electric bicycles, etc. The standard power ranges corresponding to different charging devices are different. For example, the standard power range corresponding to electric vehicle a is from 120 kilowatts to 350 kilowatts; the standard power range corresponding to electric vehicle b is from 50 kilowatts to 100 kilowatts, etc. By obtaining the parameters of each device in use, the standard power range corresponding to each charging device can be determined. The charging record contains the charging start time and the charging end time of the charging pile to be regulated.

[0086] Step S2: When the target power limit value exceeds the standard power range, determine the duration required for charging completion according to the charging record.

[0087] Specifically, the target power limit value of the charging pile to be regulated may change. In the initial stage of charging when the charging device starts charging, the target power limit value of the charging pile to be regulated may be within the standard power range. At this time, using this charging pile to be regulated can make the actual charging power of the charging device within the standard power range. If it is determined after a certain adjustment that the target power limit value of this charging pile to be regulated is outside the standard power range of the charging device, at this time, the charging device may not be able to make the actual charging power within the standard power range. If charging is carried out in this situation for a long time, it is very likely to damage the battery performance of the charging device.

[0088] When it is detected that the target power limit value of the charging pile to be regulated exceeds the standard power range, the duration required for charging completion can be determined according to the charging record of the charging device when the charging device needs to charge at the current actual charging power.

[0089] Step S3: Obtain the operating parameters of the charging pile to be regulated, and simulate the operating conditions of the charging pile to be regulated within the first preset time period based on the operating parameters and the device parameters to obtain simulated operating data. The first preset time period is a predicted duration after the current moment, where the predicted duration is the same as the duration required for charging completion.

[0090] Specifically, the operating parameters of the charging pile to be regulated may include the charging power, input voltage, output voltage, and the type of the charging pile. Among them, the charging power is the actual power value corresponding to the current moment. Based on the operating parameters of the charging pile to be regulated, a simulated charging pile model of the charging pile to be regulated can be constructed. Based on this simulated charging pile model, the operating conditions of the charging pile to be regulated in a preset time period can be simulated. The specific content of the operating parameters of the charging pile to be regulated is not specifically limited in the embodiments of the present application. The duration of the preset time period is the same as the duration required to complete charging. For example, it is detected that it still takes 30 minutes from the current moment until charging is completed, and the current moment is 10 o'clock. Then, the preset time period is between 10 o'clock and 10:30. When the target power limit value exceeds the standard power range, simulation prediction facilitates the assessment of the risks that may be generated by not timely switching the target power limit value of the charging pile to be regulated. The simulated operation data is the risk assessment result.

[0091] Step S4: Identify the simulated power value included in the simulated operation data. When the simulated power value is within the preset limit range and the duration required to complete charging is less than the preset limit duration, regulate the charging pile to be regulated based on the target power limit value in the second preset time period.

[0092] Specifically, the feature recognition method can be used to identify the simulated power value included in the simulated operation data, that is, the simulated power value of the charging pile to be regulated during the simulated operation process. When the simulated power value is within the preset limit range, it indicates that the risk level generated by not timely regulating the charging pile to be regulated according to the target power limit value is relatively low. The preset limit range can be determined by relevant staff based on historical experimental data and then uploaded to the control system. The specific content is not specifically limited in the embodiments of the present application.

[0093] Since the target power limit value is determined based on multi-dimensional considerations and is the most suitable power limit value for the current operating conditions of the charging pile to be regulated, that is, after regulating the charging pile to be regulated according to the target power limit value, the charging pile to be regulated and the power grid system are more stable and safe. If the charging pile to be regulated is not timely adjusted according to the target power limit value, the probability of abnormal conditions in the subsequent use process will increase. Through prediction simulation, the risks generated by not timely regulating the charging pile to be regulated according to the target power limit value can be evaluated. In addition, it is also necessary to analyze the duration required to complete charging. Only when the simulated power value is within the preset limit range and the duration required to complete charging is less than the preset limit duration, can the charging pile to be regulated be regulated based on the target power limit value after charging is completed. The second preset time period is a period of time after charging is completed. The specific duration is not specifically limited in the embodiments of the present application and can be set by relevant technical personnel.

[0094] When the simulated power value exceeds the preset limit range, or the duration required to complete charging is not less than the preset limit duration, the method provided by the embodiments of the present application further includes:

[0095] Based on the regulation network port number, at least one associated charging pile of the to-be-regulated charging pile is determined, and each associated charging pile has the same regulation network port number as the to-be-regulated charging pile; the associated usage records of each associated charging pile are obtained, and based on each associated usage record, the power margin corresponding to each associated charging pile is determined, and the associated charging pile with the highest power margin is determined as the target associated charging pile; according to the actual usage power value of the to-be-regulated charging pile and the corresponding target limit power value, the power difference is determined, and based on the power difference, the associated limit power value of the target associated charging pile is determined.

[0096] Specifically, when the simulated power value exceeds the preset limit range, or the duration required to complete charging is not less than the preset limit duration, it indicates that if the to-be-regulated charging pile is not adjusted according to the target limit power value in a timely manner, the probability of the to-be-regulated charging pile having an abnormality during subsequent use is relatively high. If the to-be-regulated charging pile is adjusted according to the target limit power value at this time, it may affect the safety of the charging equipment. At this time, at least one associated charging pile corresponding to the to-be-regulated charging pile can be identified and determined through the regulation network port number, and the associated limit power values of at least one associated charging pile of the to-be-regulated charging pile are further adjusted to relieve the grid load pressure, so as to facilitate maintaining the safety of the to-be-regulated charging pile and the charging equipment within the first preset time period.

[0097] There is an association relationship between the to-be-regulated charging piles belonging to the same regulation network port. Therefore, based on the regulation network port number, it is convenient to accurately identify at least one associated charging pile corresponding to the to-be-regulated charging pile. After determining at least one associated charging pile of the to-be-regulated charging pile, it is not directly adjusted randomly. Instead, first, the power margins of each associated charging pile are determined according to the associated usage records of each associated charging pile. The power margin is the difference between the limit power value and the actual usage power value, and the sum of the power margin and the actual usage power value is the limit power value. The target associated charging pile is determined from all the associated charging piles based on the power margin of each associated charging pile, where the number of target associated charging piles is not specifically limited in the embodiments of the present application. According to the actual usage power value of the to-be-regulated charging pile and the corresponding target limit power value, the power difference is determined, and finally, the associated limit power value of the target associated charging pile is adjusted based on the power difference to facilitate improving the accuracy and rate during the power value adjustment process.

[0098] By reducing the power limit of the associated charging piles of the charging pile to be regulated, the load pressure on the power grid is alleviated, thereby facilitating the guarantee of the safety and stability of the charging pile to be regulated, the power grid, and the charging equipment during the charging process of the charging equipment. In addition, regulating the target associated charging pile based on the power difference facilitates improving the regulation rate and regulation accuracy.
