[0032] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments may be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0033] In an electric vehicle shared battery system, a battery detection module is equipped for each shared battery. The charge and discharge detection unit, power detection unit, temperature detection unit, and position information unit in this module are respectively connected to corresponding sensors, such as a voltmeter, ammeter, temperature sensor, and GPS module. Photovoltaic power generation equipment and a communication module are installed in a photovoltaic charging station to ensure that it can stably collect power generation power data and upload it in real time. A cloud service platform is built, and a charging source analysis module, a battery health assessment module, and a user data management module are deployed, and a corresponding database is configured to store data. A user terminal APP is developed to implement the functions of an interface display unit, an interactive operation unit, and a message receiving unit.

[0034] Working process of the battery detection module: The charge and discharge detection unit monitors the voltage direction at both ends of the positive and negative electrodes of the battery in real time to determine whether the battery is in a charging or discharging state. The coulomb meter of the power detection unit starts to record the charging and discharging time. At the same time, the voltmeter and ammeter continuously collect voltage and current data, and calculate the charging amount and power consumption according to the integral operation rules. The temperature detection unit monitors the temperature of each part of the battery in real time through multiple temperature sensors and summarizes the data. The GPS module of the position information unit continuously obtains the real-time position information of the battery, and these data are uploaded to the cloud service platform at regular intervals.

[0035] Data upload of the photovoltaic charging station: During the operation of the photovoltaic power generation equipment in the photovoltaic charging station, the communication module collects the power generation power data in real time and uploads it to the charging source analysis module of the cloud service platform at a set time interval (such as every minute).

[0036] Data processing of the cloud service platform:

[0037] Analysis of the charging source: The charging source analysis module receives the power generation power data uploaded by the photovoltaic charging station, as well as the power data and position information when the battery is charging transmitted by the battery detection module. Using the position of the charging station obtained by GPS positioning, it compares with the known position information of the photovoltaic equipment to verify whether the charging station is connected to the photovoltaic equipment. At the same time, it analyzes the matching degree between the charging power curve and the typical local photovoltaic power generation curve, and comprehensively judges whether the charging source of the battery is photovoltaic power generation.

[0038] Battery Health Assessment: The battery health assessment module receives the battery voltage, current, temperature data uploaded by the battery detection module and the historical usage data of the battery. It obtains the real-time voltage, current, charging time of the battery and the usage time since the last charge, performs triple integral operations to obtain the charging amount and power consumption, and then performs a difference operation between the power consumption and the current state of charge of the battery to obtain the power loss. When the power loss exceeds 20% but is less than 30%, it sends a warning message to the operator; when it exceeds 30%, it issues a warning message.

[0039] User Data Management: The user data management module classifies and stores the data generated by users during the use of the system, such as registration information, battery usage records, payment records, feedback evaluations, etc., for convenient subsequent analysis and query.

[0040] User Terminal APP Interaction:

[0041] Interface Display: When the user opens the APP, the interface display unit presents the battery query results, including information such as the real-time power of the battery, health status, distance, and whether it is photovoltaic charging. During the use of the battery, the charging and discharging status, remaining power, and temperature data of the battery are displayed in real time. After the payment is completed, the payment result and expense details are displayed.

[0042] Interactive Operations: The interactive operation unit receives the user's barcode scanning operation instruction to achieve quick binding with the battery. When the user initiates a navigation request, it sends an instruction to the cloud service platform and receives the navigation route data. After the user selects a payment method, it calls the corresponding payment interface to complete the payment process. After the user enters the feedback evaluation content, it uploads it to the cloud service platform.

[0043] Message Reception: The message reception unit receives messages such as battery status anomaly reminders and system notifications pushed by the cloud service platform in real time and displays them to the user in a timely manner to ensure that the user can understand the relevant information in a timely manner.

[0044] Embodiment 1

[0045] As Figure 1 shown, an electric vehicle shared battery detection and usage system based on photovoltaic power generation provided by the present invention includes a battery, a battery detection module, a cloud service platform, an operator, and a user terminal.

[0046] First, before integrating the shared battery into the system, the operator needs to enter the health status of the battery into the system according to the information provided by the manufacturer, such as standard voltage, standard capacity, health data, etc. At the same time, a unique QR code is printed on the battery shell.

[0047] A real-time detection module is set in the battery to detect the current, voltage, temperature, and charge and discharge time of the battery. Among them, the current and voltage are measured by corresponding ammeters; the temperature data is measured by multiple temperature sensors TP1-4 inside the battery; the charge time and discharge time of the battery are measured by an internal coulomb meter IC. In addition, a GPS module is set inside the battery to send the location of the battery in real time.

[0048] The platform analyzes and processes each battery information under system control obtained, and summarizes it into intuitive data to send to the user.

[0049] The user uses the mobile phone APP to view the battery information and shares the location information through the mobile phone, and the cloud service platform gives a reasonable addressing path.

[0050] After the user finds the battery, scan the QR code drawn by the manufacturer on the battery to bind the selected battery. During use, this battery cannot be searched by other users, which can reduce the computing amount of the server. During use, the temperature sensors TP1-4 detect the battery temperature data in real time, and the voltmeter V and ammeter A detect the electric energy output data, and upload these data to the cloud. The cloud server detects whether the battery is operating normally. If dangerous operations occur such as too high temperature or unstable voltage, the user and the operator should be informed in time.

[0051] During the operation of the battery, the voltage, current, and temperature data inside the battery are read by the cloud, and the Kalman filter algorithm is used to detect the state of charge of the battery, calculate the cost generated by the user using the battery, and display the energy consumption information and cost information on the user APP in real time.

[0052] On the cloud service platform, obtain the real-time voltage U, current I, charge time t, and the usage time Δt since the last charge of the battery; the platform performs triple integral operations on the voltage, current, and time to obtain the power consumption, and then performs a difference operation with the state of charge of the battery to obtain the power loss of the battery.

[0053]

[0054] When this value exceeds 20% and is less than 30%, the platform alerts the operator, indicating that the battery life is about to expire; if this value exceeds 30%, then the platform will issue a warning to the operator, indicating that the battery life has expired and it is no longer suitable for use.

[0055] Finally, after use, the user pays the fee through the mobile phone APP. After the payment is completed, the user can give an evaluation and can also give feedback. The operator can learn about the user's usage experience in time through the platform, which is convenient for further modification.

[0056] Figure 2It is a schematic diagram of an internal detection device for shared batteries of electric vehicles. Multiple temperature sensors TP1 - TP4 are distributed inside the battery to measure the temperature, which can reflect the temperature conditions of various parts of the battery and is conducive to monitoring the thermal state of the battery. The built-in coulomb meter IC measures the charging and discharging time of the battery, and calculates the power in cooperation with the measurement of current and voltage. The GPS module sends the location of the battery in real time, facilitating the tracking of the battery location and the management and allocation of shared batteries. These components jointly provide data support for the monitoring and management of the battery state.

[0057] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
