[0002] Wind power generation, as an important green energy technology, has been widely adopted and promoted in my country. However, traditional wind power generation methods have certain shortcomings in terms of energy storage. When the current generated by wind power exceeds the voltage limit of the energy storage battery, continued charging will damage the battery, thus defeating the purpose of wind power generation. Traditional wind power charge controllers mainly use thyristors to short-circuit and lock the wind blades. Although this method can achieve control of the wind blades, it has certain limitations, such as easy overheating, damage, and poor stability. Utility Model Content

The single-chip microcomputer automatically controls the conduction and cutoff of the MOS tube according to the upper voltage limit of the energy storage battery.

[0006] A further technical solution is: the rectifier includes at least one diode for converting the alternating current generated by the fan blades into direct current.

[0017] The embodiment of the present application solves the problem that the wind energy charging controller in the existing technical solution mainly uses thyristors to short-circuit and lock the wind blades by providing a wind energy charging control device. Although this approach can achieve control of the wind blades, it has certain limitations, such as the equipment is prone to heat and damage, and has poor stability.

[0018] The technical solution in the embodiments of the present application is to solve the above problems, and the overall idea is as follows:

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] A wind energy charging control device, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the system includes fan blades, a rectifier, an energy storage battery, a MOSFET, and a microcontroller. The rotating fan blades cut magnetic flux lines, generating alternating current (AC). This DC current is rectified by the rectifier and then passes through the MOSFET to charge the energy storage battery. The microcontroller automatically controls the conduction and cutoff of the MOSFET based on the upper voltage limit of the energy storage battery. The MOSFET is a domestically produced Houyi HY3208 N-channel MOSFET with an 80V drain-source voltage and a continuous drain current of 120A. The microcontroller is a domestically produced Huimang FT61F021A microcontroller.

[0021] The rectifier includes at least one diode and is used to convert the alternating current generated by the wind blades into direct current.

[0022] The energy storage battery includes an overcharge protection module, which automatically stops charging when the energy storage battery voltage reaches the preset upper limit value Vmax.

[0023] The single chip microcomputer includes a charging indicator light control circuit. When charging is in progress, the indicator light is on. When charging is completed, the indicator light is off.

[0024] The single chip microcomputer also includes a brake control circuit, which automatically starts the brake to stop the fan blades from rotating when the voltage of the energy storage battery reaches the upper limit value Vmax.

[0025] By replacing traditional thyristors with MOS transistors, which feature lower on-resistance and faster switching speeds, the device reduces overall energy consumption and improves energy conversion efficiency. Compared to traditional thyristors, MOS transistors generate less heat, which helps reduce system temperature rise, improves product reliability and stability, and extends the device's service life. Furthermore, during battery charging, the microcontroller automatically controls the MOS transistor's conduction and cutoff states based on the battery voltage limit, effectively preventing overcharging, extending the battery's service life, and improving battery efficiency. The battery's overcharge protection not only prevents performance degradation or even damage from overcharging, but also reduces potential safety hazards. The rectifier, which includes at least one diode to convert the AC power generated by the wind blades into DC power, achieves high conversion efficiency and a simple structure, reducing manufacturing costs. Because the device also includes a charging indicator control circuit and a brake control circuit, an indicator illuminates when charging is in progress, visually indicating the charging status. When charging is complete, the indicator turns off, providing a superior user experience. At the same time, when the voltage of the energy storage battery reaches the upper limit value Vmax, the brakes are automatically activated to stop the fan blades from rotating, preventing the battery from overcharging and further ensuring the safe operation of the system.

[0026] In summary, the wind energy charging control device of the present invention demonstrates significant benefits in improving energy conversion efficiency, reducing energy consumption, enhancing product reliability, protecting battery life, improving operational safety, and providing a positive user experience. These advantages fully demonstrate the advantages of the present invention in terms of technological innovation and practical value, and it has broad application prospects.
