Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle energy supply, and particularly to a charging pile operation management system and device. Background Art

[0002] With the booming development of the electric vehicle industry, as a key infrastructure for electric vehicle energy supply, the number and scale of charging piles are growing rapidly. However, the charging piles face many problems that need to be solved urgently in terms of operation management, which poses an urgent need for the innovation and improvement of the charging pile operation management system and device.

[0003] From the perspective of the operation status monitoring of charging piles, the traditional monitoring methods have obvious deficiencies. The early monitoring means can often only obtain limited information, such as simple charging status indication, and it is difficult to collect the key parameters of charging piles in real time and accurately. For example, the subtle changes in parameters such as charging power, current, and voltage may indicate potential faults of the charging pile, but the traditional monitoring methods cannot capture these information in time, resulting in the difficulty of timely discovery and handling of faults, affecting the normal use and lifespan of the charging pile. Moreover, the lack of effective monitoring of the temperature of the charging pile may cause safety accidents, such as fires, when the charging pile is overheated due to long-term high-load operation or internal faults, seriously threatening the safety of users and equipment.

[0004] In terms of user management, the traditional operation mode cannot meet the diverse needs of users. The user registration and login processes are cumbersome, and the security of account information cannot be effectively guaranteed, easily leading to the leakage of user information. The management of charging records is also relatively chaotic, and it is difficult for users to conveniently query their charging history and expense details, reducing the user experience.

[0005] In addition, the charging standards of charging piles in different regions and different operators are not unified, and the payment methods are single, bringing great inconvenience to users. The charging scheduling problem is also an important factor restricting the operation efficiency of charging piles. During peak hours, when multiple users request charging at the same time, the traditional scheduling methods often cannot make reasonable allocations according to the real-time status of the charging piles and the actual needs of users, resulting in some charging piles being idle while some users need to wait for a long time, causing waste of resources and dissatisfaction among users. Moreover, the lack of accurate prediction of the remaining power and estimated charging time of the charging piles makes the scheduling decision lack scientificity, further reducing the charging efficiency.

[0006] In terms of fault diagnosis and maintenance management, traditional methods mainly rely on manual inspections and after-the-fact repairs, resulting in low efficiency. When a charging pile fails, it is difficult to accurately determine the type and location of the fault in a timely manner, leading to long repair times and affecting the normal operation of the charging pile. At the same time, due to the lack of effective analysis and management of fault data, it is difficult to summarize fault patterns and take preventive measures in advance, increasing operating costs and risks. Data analysis plays an important role in the operation and management of charging piles, but this is often overlooked in traditional operation models. The lack of in-depth analysis of data such as user charging habits, charging pile usage frequency, and charging demands at different times cannot provide strong support for optimizing the layout of charging piles, adjusting scheduling strategies, and improving operation services. This makes the operation of charging piles lack pertinence and scientific nature and difficult to meet the dynamic needs of the market.

[0007] In addition, the imperfect remote control function is also a major shortcoming of traditional charging pile operation management. Operations such as remotely starting, stopping, and adjusting the power of charging piles cannot be achieved. When encountering special situations such as emergency repairs or temporary scheduling, it is impossible to control the charging piles in a timely manner, reducing the flexibility and efficiency of operation management.

[0008] In summary, developing an advanced charging pile operation management system and device to solve the problems existing in the above traditional operation management, improve the operation efficiency, safety, and user satisfaction of charging piles, has important practical significance. Summary of the Invention

[0009] The charging pile operation management system and device proposed by the present invention are to solve the problems mentioned in the above prior art.

[0010] To achieve the above object, the present invention adopts the following technical solutions: A charging pile operation management system, including:

[0011] Charging pile information collection module: Real-time collection of the operating status information of the charging pile through sensors, such as charging power P, charging current I, charging voltage U, charging pile temperature T, etc. The sensors have high precision and high reliability. The charging power measurement accuracy reaches ±0.5%, the current measurement accuracy reaches ±0.2%, the voltage measurement accuracy reaches ±0.1%, and the temperature measurement accuracy reaches ±0.5°C. The collection frequency can be set according to actual needs, generally collecting data once every 5 seconds. At the same time, record the usage duration t and charging times n of the charging pile.

[0012] Charging pile status monitoring module: Based on the collected information, the working status of the charging pile is monitored in real time. The power balance formula P = U × I is used to determine whether the power of the charging pile is normal. If the deviation between the actual measured power and the power calculated by the formula exceeds ±5%, the power is determined to be abnormal. Monitor the temperature change of the charging pile. When the temperature exceeds the set safety threshold T safe At the same time, the connection status of the charging pile is monitored to determine whether the charging gun is normally connected to the vehicle. If the connection is abnormal, a corresponding prompt message is issued.

The system uses encryption technology to protect the user's account information. Record the user's charging time charge , charging power Q and charging fee C. The charging fee calculation formula is C = k × Q (where k is the charging unit price, which can be adjusted according to different time periods and regions). At the same time, it provides users with functions such as recharging and querying charging records, which facilitates users to manage their charging accounts.

[0014] Charging scheduling module: Perform charging scheduling based on the real-time status of the charging pile and the user's charging needs. Adopt an optimized scheduling algorithm, taking into account the remaining power of the charging pile and the estimated charging time t predict and user priority. The estimated charging time is calculated as follows: (where Q need The amount of electricity that the user needs to charge, P available is the available charging power of the charging pile). Emergency charging needs and charging requests of high-priority users are given priority to improve the efficiency of charging pile usage.

[0015] Furthermore, it also includes:

[0016] Fault diagnosis module: Use machine learning algorithms (such as decision tree algorithms) to analyze the collected charging pile operation data to diagnose whether the charging pile has a fault. Establish a fault feature library, compare the collected data with the fault feature library, and determine the fault type. For example, when the charging current suddenly drops and the power is abnormal, it may be a charging line fault. (Where D is the fault diagnosis accuracy, N correct-diagnose is the number of faults correctly diagnosed, N total-diagnose The accuracy of fault diagnosis is evaluated by the total number of faults diagnosed. When a fault is diagnosed, the maintenance personnel are notified in time to carry out maintenance.

[0017] Data analysis module: Deeply analyze the operation data of charging piles, including users' charging habits, the usage frequency of charging piles, charging demands at different times, etc. Discover potential rules and correlation relationships in the data through data mining algorithms (such as association rule mining). For example, it is found that the charging demand in certain areas is relatively high during specific time periods. Optimize the layout and scheduling strategies of charging piles using the data analysis results to improve operation efficiency. At the same time, through the user satisfaction formula (where S is the user satisfaction, R i is the satisfaction score of the i-th user, and n is the total number of users) to evaluate the user satisfaction with the operation service of charging piles.

[0018] Furthermore, it also includes:

Set up operation permission management, and only authorized personnel can perform remote control operations. During the remote control process, real-time monitor the response status of the charging piles to ensure the effectiveness of control operations.

[0020] Charging management module: Conduct charging management based on the charging power and charging duration of users. Adopt multiple charging methods, such as charging by power, charging by time, or a combination of both. The charging standard can be adjusted according to different operation strategies and market conditions. At the same time, support multiple payment methods, such as WeChat payment, Alipay payment, bank card payment, etc. Ensure the accuracy of charging through the charging accuracy formula (where F is the charging accuracy, N correct-charge is the number of orders with accurate charging, and N total-charge is the total number of charging orders).

[0021] Furthermore, when the fault diagnosis module conducts fault diagnosis, it combines the historical fault data of the charging piles and real-time environmental factors (such as temperature, humidity). Use the environmental impact coefficient E to correct the fault diagnosis results. The calculation formula of the environmental impact coefficient is E = α × T × β × H (where T is the environmental temperature, H is the environmental humidity, and α and β are preset coefficients). By considering environmental factors, improve the accuracy and reliability of fault diagnosis.

[0022] Furthermore, when the data analysis module analyzes users' charging habits, it uses clustering analysis algorithms (such as the K-Means algorithm) to classify users.

At the same time, combine the geographical location information of users to optimize the layout of charging piles and improve the utilization rate of charging piles.

[0023] Furthermore, when the remote control module performs remote control, it adopts a dual authentication mechanism, including user identity authentication and device authentication. Users need to enter the correct username, password, and dynamic verification code for identity authentication, and the device needs to be authenticated through the device unique identifier and digital certificate. Through the dual authentication mechanism, the security of remote control is improved, and illegal operations are prevented.

[0024] Furthermore, when the charging management module processes payments, it adopts a combination of real-time settlement and regular settlement. For small charging fees, the real-time settlement method is adopted, and users complete the payment immediately after charging. For large charging fees or enterprise users, the regular settlement method is adopted, and settlements are made monthly or quarterly.

[0030] Furthermore, the information collection device also includes a fault detection sensor for detecting the fault information of the charging pile. The fault detection sensor can real-time monitor the working status of the key components of the charging pile (such as the charging module, battery management system). When a fault is detected, the fault information is transmitted to the management system in a timely manner.

[0031] Furthermore, the communication device has the function of automatically switching communication modes. When one communication method fails, it can automatically switch to another communication method to ensure the continuity of communication. For example, when the 4G signal is unstable, it automatically switches to Ethernet communication.

[0032] Furthermore, the control device has a fault protection function. When abnormal situations (such as overcurrent, overvoltage, overheating) occur in the charging pile, it can automatically stop charging and take corresponding protection measures to ensure the safety of the charging pile and the vehicle.

[0033] Furthermore, the display device has a touch operation function. Users can perform charging operations, query charging records, and set charging parameters by touching the screen.
