Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Embodiment

[0021] As Figure 1 and Figure 2 shown, a shared electric vehicle charging system disclosed by the present invention includes a charging request device 201, a communication base station 203, a cloud intelligent management system 204, an electric vehicle charging station 202, and a battery management system 205.

[0022] The charging request device 201 includes a mobile terminal or a fixed terminal. The charging request device 201 can be a mobile application, an in-vehicle system, or other intelligent devices, and initiates a charging request to the communication base station 203 through an application program or an interactive interface, for generating and sending a charging request signal. The charging request device 201 further includes a GPS positioning module for obtaining data of the user's current location. The charging request device 201 further includes an identity authentication module. The user identity authentication module can be a mobile phone number, biometric information, or other identity authentication methods, for verifying user permissions to restrict illegal operations, ensuring that only legitimate users can use the charging service, and preventing illegal operations and abuse of system resources.

[0023] The communication base station 203 includes a wireless communication base station or a wired data transmission link, for receiving and transmitting the charging request signal, transmitting the charging request sent by the user to the cloud intelligent management system 204 through the network or wireless communication. After receiving the charging request, the cloud intelligent management system 204 transmits the request information to the electric vehicle charging station 202 through the communication platform 2043, realizing data interaction among the charging request device 201, the cloud intelligent management system 204, and the electric vehicle charging station 202.

[0024] The cloud intelligent management system 204 is used to process the charging request signal and generate a charging control signal based on a preset scheduling strategy. The cloud intelligent management system 204 is communicatively connected to the electric vehicle charging station 202 to coordinate the allocation of charging resources, control the charging process, and complete the billing and feedback of charging data. The cloud intelligent management system 204 also includes an intelligent scheduling module, which can intelligently schedule the most suitable charging pile 2022 and charging station according to data such as the idle situation of the charging station, the charging needs of users, and the geographical location of the charging station, so as to optimize the use of charging resources, reduce the waiting time of users, and improve the charging efficiency. It is used to dynamically allocate the optimal charging resources according to the idle state of the charging pile 2022, the user's location and charging needs. The cloud intelligent management system 204 also includes an account management platform 2041, an order management platform 2042 and a communication platform 2043. The account management platform 2041 is responsible for the full life cycle management of user identities, including registration, login, permission verification and account information maintenance. It verifies the legitimacy of users through the user identity authentication module to ensure that only authorized users can use the charging service; stores and manages user personal information, charging history records, payment account binding information, etc.; provides an account security protection mechanism to prevent the account from being stolen or illegally operated. The order management platform 2042 is used to coordinate the order generation, execution monitoring and settlement of the entire charging service process. The communication platform 2043 serves as a data transmission hub inside and outside the system to ensure efficient communication between components.

[0025] The electric vehicle charging station 202 includes an electric energy metering module 2023, a communication module 2021 and at least one charging pile 2022. The communication module 2021 is used for signal transmission between the cloud intelligent management system 204 and the charging pile 2022. The charging pile 2022 is used to receive the charging control signal and perform a charging operation on the electric vehicle, and can receive and execute the charging control signal in real time, and at the same time upload the data of the battery management system 205 to ensure the safety and efficiency of the charging process. The electric energy metering module 2023 is used to record the charging power in real time and generate billing data. The billing data is uploaded to the cloud intelligent management system 204 through the communication module 2021. The electric energy metering module 2023 also includes an intelligent billing function. The intelligent billing function automatically calculates and generates a charging bill according to the actual charging amount, charging duration of the electric vehicle and the selected charging package, and sends the billing data to the cloud intelligent management system 204 through the communication module 2021. The cloud intelligent management system 204 completes the payment operation according to the account information of the user management platform.

[0026] Refer to Figure 3, the battery management system 205, is connected to the electric vehicle charging station 202 and is used to monitor the battery state parameters in real time and trigger the charging interruption mechanism when an abnormality is detected. The battery management system 205 includes: a battery monitoring module 301, which is used to collect the voltage, current and temperature parameters of the battery in real time; a fault diagnosis module 302, which is used to monitor the working state of the battery and the parameters such as current, voltage and temperature during the charging process in real time. When an abnormality is detected during the battery charging process, it automatically triggers a fault protection program and sends an alarm notification to the user and the operator through the cloud intelligent management system 204 so as to take measures in time; an equalization management module 303, which is used to ensure the voltage balance between the individual battery cells in the battery pack. When it is found that the voltage of a certain unit battery is too different from that of other units, the equalization management module 303 will perform an energy equalization operation to avoid performance mismatch between the battery cells and extend the overall life of the battery; a battery protection module 304. When an abnormality occurs in the battery, the battery protection module 304 automatically takes protection measures, such as cutting off the connection between the battery and the electric vehicle, to ensure the safety of the battery and the user. The battery management system 205 can also interact with the power system of the electric vehicle to feedback information such as the battery charging state and health status in real time, helping the user to understand the usage situation of the battery in time and extending the service life of the battery.

[0027] As Figure 4 shown, a charging method for a shared electric vehicle charging system disclosed by the present invention includes the following steps: S1. Receive a charging request initiated by the user through the charging request device 201; S2. Analyze the request data through the cloud intelligent management system 204 to generate a charging control signal and allocate a target charging pile 2022. The system uses big data and intelligent scheduling algorithms to quickly screen out the nearby idle charging piles 2022 and judge whether they meet the user's charging requirements (such as the charging power, type, and whether it is idle supported by the charging pile 2022, etc.). If the system successfully finds a charging station that meets the conditions, it will provide options to the user; S3. The user connects to the target charging pile 2022 and starts the charging process. The user inserts the charging gun into the charging port of the electric vehicle, and the electric vehicle establishes a communication connection with the charging pile 2022 to confirm information such as the battery type and power demand. After the connection is successful, the charging pile 2022 will display the charging status and start to prepare to provide power to the electric vehicle; S4. The charging parameters are adjusted in real time through the battery management system 205, and charging is interrupted in case of anomalies. The electric vehicle charging station 202 charges according to the charging request. After successful connection, the charging pile 2022 will display the charging status and start preparing to supply power to the electric vehicle. Through the intelligent battery management system 205, the charging pile 2022 will adjust parameters such as voltage and current in real time to ensure that the battery is charged within a safe range. Users can view the charging progress in real time through the application or the interface of the charging pile 2022, such as battery power, charging duration, charging power, etc. The system will record data such as charging time and power in real time and automatically calculate the cost according to the preset charging standard. The adjustment of the charging parameters includes dynamically matching the voltage, current and charging power to optimize the safety performance of charging, charging efficiency and extend the battery life; S5. After charging is completed, the cost is automatically settled based on the power metering data and the system status is updated. Once the charging termination signal is sent, the cloud platform will update the status of the charging pile 2022 and record the charging data (such as total charging duration, power, cost, etc.). At the same time, the user will receive a charging end notification through the application or the display screen. When the battery reaches the set charging threshold (usually 90%-100%), the charging pile 2022 will automatically stop charging and send a charging termination signal to the cloud intelligent management system 204. If the user chooses to abort charging in advance (such as through the application, the interface of the charging pile 2022, etc.), the charging pile 2022 will also send a charging termination signal to the cloud platform. After charging is completed, payment is made in the user's account. After the payment is completed, the user can remove the charging gun from the charging port of the electric vehicle.

[0028] In summary, through the cloud intelligent management system 204, the present invention significantly improves the charging efficiency and overall resource utilization rate. Through the battery monitoring module 301, potential safety hazards are effectively prevented, ensuring the safety of users, vehicles and charging facilities. The cloud intelligent management system 204 integrates an intelligent charging function, reducing manual operations and management costs. The battery management system 205 is built-in with an equalization management module 303, extending the overall battery life and reducing the maintenance investment of operators. Real-time data monitoring and intelligent scheduling strategies reduce energy waste, and the fault warning mechanism ensures quick response. Combining cloud data management optimizes long-term operation strategies, enhancing system stability and environmental friendliness.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
