[0002] With the rapid development of economy and technology, transportation, economic construction, and people's pursuit of quality of life, the development of clean energy has become a key development project. The use of non-renewable energy in the past has posed a huge challenge to the environment. The automotive industry is a pillar industry of the country and plays a key role in the goal of new energy development. Therefore, new energy vehicles have also developed rapidly. However, range anxiety has always plagued consumers' choices. Therefore, developing new energy charging technology has become a technical problem that major OEMs and battery manufacturers need to overcome.

[0003] Therefore, it is necessary to provide a new automotive hybrid energy power generation system and its control method to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this disclosure is to provide an automotive hybrid energy power generation system and its control method in order to solve the above-mentioned problems.

[0005] This disclosure achieves the above objectives through the following technical solutions: A vehicle-mounted hybrid energy power generation system includes a wind power generation module, a solar power generation module, a mechanical energy power generation module, a transformer, a vehicle control unit, and a battery installed on the vehicle. The wind power generation module includes several wind turbines mounted on the front bumper air intake grille, and the wind turbines are connected to the vehicle control unit through the transformer; The solar power generation module includes a solar glass assembly mounted on the roof sunroof glass assembly, and the solar glass assembly is connected to the vehicle control unit via the transformer; The mechanical energy generation module includes a thin-film tapping friction nanostructure glass body installed on the roof glass assembly, and the thin-film tapping friction nanostructure glass body is connected to the vehicle control unit through the transformer; The battery is connected to the vehicle control unit.

[0006] As a further optimization of this disclosure, the number of wind turbines is three.

[0007] As a further optimization of this disclosure, the thin-film tapping friction nanostructured glass body includes an inner glass sheet, a PVB layer, a conductive copper foil, a thin-film tapping friction nanolayer, and an outer glass sheet; the PVB layer is disposed on the top side of the inner glass sheet, the conductive copper foil is disposed on the top side of the PVB layer, the thin-film tapping friction nanolayer is disposed on the top side of the conductive copper foil, and the outer glass sheet is disposed on the top side of the thin-film tapping friction nanolayer.

[0008] As a further optimization of this disclosure, a thin film tapping friction nanolayer is deposited on the inner surface of the outer glass sheet.

[0009] As a further optimization of this disclosure, it also includes an energy storage cell, a bidirectional DC-DC converter, a high-voltage battery, and a high-voltage electrical appliance. The energy storage cell and the bidirectional DC-DC converter are both connected to the vehicle control unit; the high-voltage battery is connected to the bidirectional DC-DC converter, and the bidirectional DC-DC converter is connected to the high-voltage electrical appliance.

[0010] As a further optimization of this disclosure, the energy storage cell is connected to a high-voltage controller, which is connected to the high-voltage battery.

[0011] As a further optimization of this disclosure, the energy storage cell is connected to a low-voltage controller, the vehicle controller is connected to a low-voltage electrical appliance, and the low-voltage controller is connected to the low-voltage electrical appliance.

[0012] As a further optimization of this disclosure, it also includes an inverter, wherein the wind power generation module, the solar power generation module and the mechanical power generation module are all connected to the transformer through the inverter.

[0013] As a further optimization of this disclosure, the maximum power point tracking (MPPT) technology is used to ensure that the wind power generation module, the solar power generation module, and the mechanical power generation module always maintain the maximum power output point, so as to maximize the electrical energy generated by solar energy, wind energy, and mechanical energy.

[0014] A control method for the aforementioned automotive hybrid power generation system includes: The system converts wind energy, solar energy, and mechanical energy into electrical energy through wind power generation modules, solar power generation modules, mechanical energy generation modules, and inverters. The vehicle control unit identifies the low-voltage components that require power and outputs power accordingly. When there is no need to supply power to low-voltage electrical appliances, the vehicle control unit will determine whether there is remaining power to charge the high-voltage battery pack based on the existing power. If the output power can still reach the preset value, it will automatically perform voltage boosting to charge the high-voltage battery. At the same time, it will prioritize starting the bidirectional DC-DC converter to boost the voltage from low voltage to high voltage, and charge the high-voltage battery and supply power to high-voltage electrical appliances through the high-voltage charging bus, while monitoring changes in power generation. Once the power supply to both the low-voltage and high-voltage electrical appliances in the vehicle is complete, the vehicle control unit will determine whether further charging is needed based on the power supply status. When charging is not required, the electricity generated by clean energy will be stored in the energy storage cell. The energy storage cell will then be used to input the stored electricity to the relevant load electrical appliances based on the vehicle's power consumption.

[0015] The beneficial effects of this disclosure are as follows: This disclosure combines solar energy, wind energy, and thin-film triboelectric nanogenerators and applies them to automobiles to supplement the insufficient power output of existing single devices, thereby meeting the vehicle's power needs and increasing driving range.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] like Figure 1 As shown, an automotive composite energy power generation system includes a wind power generation module, a solar power generation module, a mechanical energy power generation module, a transformer, a vehicle control unit, and a battery installed on the vehicle. The wind power generation module includes several wind turbines 2 mounted on the front bumper air intake grille 1, and the wind turbines 2 are connected to the vehicle control unit via the transformer; in this embodiment, as Figure 2 As shown, three fans 2 of different sizes are installed on the front bumper air intake grille 1. The selection of these fans 2 can be uniform in size according to the grille layout. During vehicle movement, the front will be subject to strong airflow resistance, which drives the fans 2 to generate electricity. The three motors 2 can also generate electricity using wind energy when the vehicle is parked in a place with a large airflow. The position of the fan 2 in the direction of the resistance generated during vehicle movement can meet the maximum wind force requirements during vehicle movement without affecting the overall vehicle shape, thus maintaining the overall aesthetics while meeting the requirements for wind power generation. The solar power generation module includes a solar glass assembly 3 mounted on the roof sunroof glass assembly, and the solar glass assembly 3 is connected to the vehicle control unit via the transformer; The mechanical energy generation module includes a thin-film tapping friction nanostructured glass body 4 mounted on the roof glass assembly. This glass body 4 is connected to the vehicle control unit via a transformer. The glass body 4 comprises an inner glass sheet 5, a PVB layer 6, a conductive copper foil 7, a thin-film tapping friction nanostructured layer 8, and an outer glass sheet 9. The PVB layer 6 is disposed on the top side of the inner glass sheet 5, the conductive copper foil 7 is disposed on the top side of the PVB layer 6, the thin-film tapping friction nanostructured layer 8 is disposed on the top side of the conductive copper foil 7, and the outer glass sheet 9 is disposed on the top side of the thin-film tapping friction nanostructured layer 8. A layer of the thin-film tapping friction nanostructured layer 8 is deposited on the inner surface of the outer glass sheet 9. This converts the mechanical energy generated by wind and rain into electrical energy.

[0020] By optimizing wind power generation modules, solar power generation modules, and mechanical power generation modules through MPPT (Maximum power point tracking), the solar, wind, and mechanical power generation equipment are always kept at the maximum power output point, thereby improving their conversion efficiency and maximizing the electrical energy generated by vehicle-mounted solar, wind, and mechanical energy. Electrical energy is converted through an inverter (not shown in the diagram); The vehicle control unit will automatically allocate power according to the output of the inverter. First, it will determine which low-voltage components need power, and then output power; see the power supply status below. (i) When the interior temperature reaches 38°C, the temperature sensor of the vehicle control unit will sense the change in interior temperature, the blower will start working, and the battery charging will stop. (ii) Detect the low-voltage battery status. If the voltage is below 13V, perform battery charging; if the voltage is ≥13V, the controller stops the charging function. (iii) Other low-voltage electrical appliances can be charged by the battery, and the vehicle control unit is responsible for monitoring the battery status. When there is no need for low-voltage electrical appliances to provide power, the vehicle control unit will determine whether there is enough power to charge the high-voltage battery based on the existing power. If the output power can still reach more than 380W, it will automatically perform voltage boosting and charge the high-voltage battery through the inverter. Simultaneously, the bidirectional DC-DC converter is activated first to boost the voltage from low to high, charging the high-voltage battery and supplying power to high-voltage electrical appliances through the high-voltage charging bus, while monitoring changes in power generation.

[0021] When the low-voltage and high-voltage electrical power supply of the whole vehicle is completed, the vehicle control unit will determine whether it is necessary to continue charging based on the power supply status. When it is not necessary to charge the electrical appliances, the electricity generated by the clean energy will be stored in the energy storage cell.

[0022] The energy storage cells can then input the stored energy back to the relevant load electrical appliances based on the vehicle's overall power consumption, thereby realizing the recycling of electrical energy. This disclosure offers a novel method for charging new energy vehicles from a different perspective. The discovery of this structural design provides a possibility for the future integration of clean energy into vehicles. From a cost perspective, combining wind, solar, and thin-film tapping friction nanotechnology with mechanical energy in automobiles will increase costs. However, from a performance and benefit perspective, it will provide the vehicle with a considerable supply of external clean energy, continuously replenishing its power regardless of weather conditions and increasing its driving range.

[0023] The embodiments described above are merely examples of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent disclosure. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
