[0025] The utility model is further described in detail below in conjunction with the full text.
[0026] Combined with Figure 1-Figure 3 A photovoltaic canopy device for an electric vehicle includes a canopy body 1, wherein the canopy body 1 includes an outer glass layer 101, an upper PVB film 102, a solar canopy layer 103, a lower PVB film 104, and an inner glass layer 105 from top to bottom. Specifically, the solar canopy layer 103 is a polycrystalline silicon photovoltaic panel, and the canopy body 1 replaces the traditional sheet metal top cover. When the utility model is implemented, the photovoltaic power generation system also includes a battery and a controller, and the polycrystalline silicon photovoltaic panel is connected to the battery through the controller. The function of the controller is to adjust the voltage and current output by the polycrystalline silicon photovoltaic panel to match the charging requirements of the battery. When there is sufficient sunlight, the current generated by the polycrystalline silicon photovoltaic panel is adjusted by the controller to charge the battery. When the battery is fully charged, the controller will automatically cut off the charging circuit to prevent overcharging from damaging the battery.
[0027] When the utility model is implemented, Figure 1 and Figure 2 As shown, a canopy sealing strip 2 is installed on both sides of the canopy main body 1, a vehicle body side panel 4 is installed on the side of the canopy sealing strip 2 away from the canopy main body 1, a rubber blocking strip 3 is installed on the lower end of the canopy sealing strip 2, and a rear top cover plate 5 is installed on the end of the rubber blocking strip 3 away from the canopy main body 1.
[0028] Specifically, the rubber strip 3 is an EPDM rubber strip. The EPDM rubber strip can withstand the erosion of ultraviolet rays, oxygen, ozone and extreme temperatures, has strong weather resistance, and can maintain its performance for a long time. Even after long-term compression or deformation, the EPDM rubber strip can quickly return to its original state, which makes it very useful in applications that require frequent expansion and contraction. The EPDM rubber strip has good chemical corrosion resistance to many chemical media, and can resist brake fluid, water, coolant, detergent, strong alkali and other chemical media. The EPDM rubber strip has good electrical insulation properties and is suitable for protecting key components such as circuit boards and batteries during the manufacturing process of electronic equipment to prevent the intrusion of moisture and dust. The EPDM rubber strip can remain flexible and elastic in a low temperature environment of -60°C, and work continuously in a high temperature environment above 110°C. The EPDM rubber strip has excellent air tightness and water tightness, and is suitable for sealing needs under various environmental conditions.
[0029] When the utility model is implemented, Figure 2 and Figure 3 As shown, the rear roof panel 5 and the body side panel 4 are welded together, and the outer side of the body side panel 4 is the rear door.
[0030] The thickness of the inner glass layer 105 and the outer glass layer 101 is 1-3 mm.
[0031] The thickness of the inner glass layer 105 and the outer glass layer 101 is 2 mm.
[0032] The thickness of the solar canopy layer 103 is 0.1-0.3 mm.
[0033] The thickness of the solar canopy layer 103 is 0.2 mm.
[0034] The thickness of the upper PVB film 102 and the lower PVB film 104 is 0.5-1.0 mm.
[0035] The thickness of the upper PVB film 102 and the lower PVB film 104 is 0.76 mm.
[0036] Specifically, the thickness of each layer of the outer glass layer 101, the upper PVB film 102, the solar canopy layer 103, the lower PVB film 104 and the inner glass layer 105 can be manufactured within the specified range according to actual conditions. However, when the thickness of the upper PVB film 102 and the lower PVB film 104 is 0.76 mm, the thickness of the solar canopy layer 103 is 0.2 mm, and the thickness of the inner glass layer 105 and the outer glass layer 101 is 2 mm, the efficiency of the canopy body 1 in converting light received into electrical energy is maximized while ensuring the thickness of the canopy body 1 itself.
[0037] The working principle of this utility model:
[0038] When sunlight shines on polycrystalline silicon photovoltaic panels, photons hit the silicon atoms in the battery, causing them to release electrons. These free electrons form an electric current inside the cell, which is called photocurrent. Polycrystalline silicon photovoltaic panels draw out this current through positive and negative electrodes and supply it to external circuits. Batteries are devices that can store electrical energy. They convert electrical energy into chemical energy through internal chemical reactions and store it. When electricity is needed, the battery converts chemical energy into electrical energy through reverse reactions and releases it. The function of the controller is to adjust the voltage and current output by the polycrystalline silicon photovoltaic panel to match the charging requirements of the battery. When there is sufficient sunlight, the current generated by the polycrystalline silicon photovoltaic panel is adjusted by the controller to charge the battery. When the battery is fully charged, the controller will automatically cut off the charging circuit to prevent overcharging from damaging the battery.
[0039] The above describes the utility model and its implementation methods, which is not restrictive. What is shown in the full text is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
