[0002] With the rapid development of the new energy vehicle industry, the demand for diversified and cleaner on-board energy replenishment is becoming increasingly prominent. Solar energy, as a renewable and clean energy source, is widely used in the field of on-board auxiliary charging.

[0054] Working principle: Based on the sunroof size of the target vehicle model, adjust the relative position of the adjusting rod 4 and the mounting frame 2, and lock and fix them by bolt assembly with the strip groove 5 and positioning hole 201 to complete the frame size adaptation;

[0055] The mounting base 1's bottom groove 9, side groove 10, and the adjusting rod 4's inner groove 401 are used to align with the original sunroof hole to complete the embedded installation. The sealing gasket 11 fills the gap to achieve a seal.

[0056] The light monitoring component 14 is activated, and each sensor collects the light azimuth angle, elevation angle, light intensity, and voltage and current data at the output terminal of the photovoltaic panel 13. The MCU controller performs threshold judgment on the light intensity. When it is lower than the preset threshold, it outputs a sleep command and controls the system to enter a low-power sleep state to reduce energy consumption.

[0057] When the light intensity exceeds a preset threshold, the MCU controller outputs an angle adjustment command based on the light angle data. The drive component 1702 uses a servo motor. When the servo motor starts, it drives the screw 1704 and the slide 1705 to move. Through the support rod 18, it pushes the sealing frame 12 to rotate, adjusting the photovoltaic panel 13 to a tilt angle that matches the light intensity. The photovoltaic panel 13 converts solar energy into electrical energy.

[0059] Example 2:

[0060] This embodiment is basically the same as the previous embodiment, except that the monitoring algorithm of the light monitoring component includes the following steps:

[0061] S1. The solar azimuth sensor collects the azimuth and elevation angle data of the illumination in real time, the illumination intensity sensor collects the illumination intensity data in real time, and the voltage and current sensor collects the voltage and current data of the photovoltaic panel output terminal in real time. The objects collected by the solar azimuth sensor, illumination intensity sensor, voltage and current sensor are clearly defined to ensure the comprehensiveness and real-time nature of core data such as illumination angle, illumination intensity, and circuit parameters, so as to provide accurate data support for subsequent control decisions.

[0062] S2. The MCU controller performs threshold judgment on the collected light intensity data. When the light intensity data is lower than the preset threshold, the MCU controller outputs a sleep command, and the control system enters a low-power sleep state. By filtering the light intensity data through the MCU controller, ineffective power generation under weak light conditions is avoided, reducing system energy consumption and improving energy utilization efficiency.

[0063] S3. When the light intensity data is higher than the preset threshold, the MCU controller calculates the optimal tilt angle of the photovoltaic panel based on the collected azimuth and elevation angle data and the installation angle limit parameters of the photovoltaic panel.

[0064] The algorithm formula for the MCU controller to calculate the optimal tilt angle of the photovoltaic panel is as follows: ;

[0065] in The optimal tilt angle for photovoltaic panels The elevation angle of illumination. This refers to the initial installation angle of the photovoltaic panels. This is the angle correction factor, and the range of values ​​for the angle correction factor is... ;

[0066] By using standardized algorithm formulas and combining real-time light data with initial installation parameters, the optimal tilt angle of the photovoltaic panel 13 is accurately calculated, avoiding blind angle adjustment and improving the accuracy and efficiency of angle adjustment.

[0067] S4. The MCU controller outputs an angle adjustment command to the angle adjustment component based on the calculated optimal tilt angle, driving the photovoltaic panel to adjust to the target tilt angle; the calculated optimal tilt angle is converted into a specific angle adjustment command to ensure that the action of the angle adjustment component 17 accurately corresponds to the optimal light-gathering requirements, and to ensure that the photovoltaic panel 13 is always in an efficient light-gathering posture.

[0068] S5. The MCU controller monitors the output power of the photovoltaic panel in real time based on the data collected by the voltage and current sensors. At the same time, it dynamically adjusts the output frequency of the angle adjustment command in combination with the operating parameters of the energy management module to keep the photovoltaic panel in the maximum power output state. By using the output power data of the photovoltaic panel 13 fed back in real time by the voltage and current sensors and combining it with the operating parameters of the energy management module, the output frequency of the angle adjustment command is dynamically adjusted to achieve closed-loop optimization of angle adjustment and ensure that the photovoltaic panel 13 can always maintain the maximum power output state when the light conditions change dynamically.

[0069] Working principle: After the light monitoring component 14 is started, each sensor collects the light azimuth angle, elevation angle, light intensity and voltage and current data of the output terminal of the photovoltaic panel 13 respectively;

[0070] The MCU controller performs threshold judgment on the light intensity. When the light intensity is lower than the preset threshold, it outputs a sleep command to enter a low-power state. When the light intensity is higher than the preset threshold, it enters the subsequent angle calculation and adjustment stage.

[0071] The MCU controller calls a preset algorithm to adjust the illumination height angle. 13 Initial installation angle of photovoltaic panels Substitute into the formula ( For the optimal tilt angle, for Correction factor), combined with correction factor The optimal tilt angle of photovoltaic panel 13 was calculated. Correction factor The calculation accuracy can be ensured by making minor adjustments based on the sunroof installation characteristics of the vehicle model.

[0072] The MCU controller adjusts the tilt angle accordingly. The output adjustment command drives the angle adjustment component 17 to adjust the photovoltaic panel 13 to the target angle.

[0073] During power generation, voltage and current sensors continuously collect and feed back output power data. The MCU controller, in conjunction with the operating parameters of the energy management module, dynamically adjusts the angle adjustment command output frequency and fine-tunes the tilt angle of the photovoltaic panel 13 to ensure that it always maintains the maximum power output state when the illumination changes dynamically.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
