Technical Field
[0001] The present application relates to the field of new energy, and in particular to a roof-mounted wind-solar integrated vehicle power generation device. Background Art
[0002] In the past few years, technological innovation and battery efficiency improvements in the field of new energy vehicles, especially electric vehicles (EVs), have significantly changed the automotive industry. The core of electric vehicles, advanced battery technology, especially the development of lithium-ion batteries, has achieved remarkable progress. These advances are reflected in the significant improvement of battery energy density, which enables electric vehicles to travel farther on a single charge. At the same time, the reduction of battery size and weight further improves the overall performance and efficiency of the vehicle. These technological developments not only increase the range of electric vehicles, but also provide electric vehicles with stronger market competitiveness.
[0003] At the same time, new energy vehicles play an important role in reducing environmental pollution and promoting sustainable development. Compared with traditional internal combustion engine vehicles, they use electricity instead of fossil fuels to significantly reduce tail gas emissions, providing an effective solution to combat climate change and air pollution. The growing global focus on reducing greenhouse gas emissions and achieving sustainable development goals has made new energy vehicles a key force in promoting these environmental goals.
[0004] However, despite the advancements in electric vehicles, range anxiety remains a significant challenge. This anxiety is mainly due to the relatively limited driving range of electric vehicles and the lack of charging infrastructure. Although battery technology has made significant progress, in some cases, the range of electric vehicles is still not comparable to that of traditional vehicles. In particular, in remote or suburban areas, the lack or uneven distribution of charging stations further exacerbates the range anxiety problem.
[0005] In summary, new energy vehicles, especially electric vehicles, have made great progress in technological innovation and battery efficiency, which not only enhances their market appeal, but also has a positive impact on environmental protection and sustainable development. However, range anxiety is still a key issue that needs to be addressed, which affects the popularity of electric vehicles and the user experience. Utility Model Content

[0037] Figures 1 to 6 An exemplary structure for implementing the present application is shown, which is a roof-mounted wind-solar integrated vehicle power generation device. In this embodiment, it is mainly composed of a box 1, a wind power generation component 2, an energy storage module 3, a fixed photovoltaic panel 4, a BMS control board 5 and a heat dissipation component (not shown in the figure). Among them, the wind power generation component 2 is installed in a horizontal through-flow channel 6 opened in the box 1 for realizing wind power generation. The fixed photovoltaic panel 4, which is the basis of photovoltaic power generation, is installed on the top surface of the box 1. In order to further improve the efficiency of photovoltaic power generation and fill the sunshade when necessary, the box 1 is installed with at least one horizontally retractable photovoltaic panel 7. The retractable photovoltaic panel 7 is also connected to the BMS control board 5 to supply power to the energy storage module 3. After the retractable photovoltaic panel 7 is pulled out, the photovoltaic area is increased and the vehicle sunshade is realized.
[0038] In terms of structure, according to needs, the fixed photovoltaic panel 4 and the telescopic photovoltaic panel 7 can be a whole piece, or a collective panel body composed of multiple small photovoltaic panels.
[0039] Specifically, the box body 1 serves as the structural basis of the device, load-bearing and fixing various components or parts. It adopts a fluid structure design, which is not only streamlined in appearance and closely matches the top contour of the vehicle to reduce wind resistance during driving, but is also made of flame-retardant and heat-insulating materials to enhance safety and durability.
[0040] In this embodiment, the energy storage module 3 is installed in the housing 1 to store the electric energy generated by wind power and photovoltaics, and discharge it when needed. In the specific description of the energy storage module 3, the energy storage module 3 is responsible for storing the electric energy generated by the wind power generation component 2 and each photovoltaic panel. It is usually composed of a plurality of battery cells, which may be lithium-ion batteries, nickel-metal hydride batteries or other types of rechargeable batteries, selected according to energy density, charge and discharge cycle life and cost. The battery cells are configured in series and parallel according to the required voltage and capacity. Series connection can increase the total voltage, while parallel connection can increase the total current and capacity.
[0041] In the above composition, the BMS control board 5 is one of the cores of the device, connecting the wind power generation component 2, the fixed photovoltaic panel 4, the telescopic photovoltaic panel 8 and the energy storage module 3. It is responsible for monitoring energy generation, storage and distribution. In the specific description of the BMS control board 5, the BMS control board 5 plays a core role in the roof-mounted wind-solar integrated vehicle power generation device, and its circuit composition and working principle are the key to ensuring the efficient and safe operation of the entire system. Specifically, the BMS control board 5 contains multiple key circuits: the voltage and current monitoring circuit uses high-precision sensors and converters to monitor the voltage and current of the energy storage module in real time to ensure that the data is accurate; the charging control circuit is responsible for managing the charging process of the photovoltaic panel and the wind power generation component to the energy storage module, usually including a power converter (such as a DC-DC converter) to adjust the voltage and current to a level suitable for the energy storage module; the temperature monitoring circuit continuously monitors the temperature of the energy storage module and other key components to ensure that the device always operates within a safe temperature range. The control board has at least one microcontroller unit, which processes all sensor data, manages the charging and discharging process of the battery, and performs fault diagnosis.
[0042] In addition, the BMS control board 5 also includes a communication interface for data exchange with other vehicle systems, such as a CAN bus. During the charging process, when each photovoltaic panel and wind power generation component 2 generates electricity, the MCU will intelligently adjust the charging process according to the current state of the energy storage module, such as power and temperature, to ensure that the battery is charged in the best way. At the same time, the MCU uses preset algorithms and safety parameters to calculate the best charging strategy and power distribution, and monitors potential safety risks, such as excessive or low voltage, abnormal current, etc., and takes necessary protective measures. The BMS control board 5 ensures that the photovoltaic panels and wind power generation components can efficiently and safely charge the energy storage module 3 while maintaining the stability and safety of the entire system.
[0043] In the above composition, the heat dissipation component is installed in the box 1 and cooperates with the energy storage module 3 to achieve temperature control of the energy storage module 3. In the specific description of the heat dissipation component, in order to achieve heat dissipation of the energy storage module 3, an air duct dedicated to heat dissipation is designed inside the box 1, which is used to effectively dissipate the heat of the energy storage module 3 and keep it working at the optimal operating temperature. The heat dissipation duct is combined with other heat dissipation components in the box to enhance the heat dissipation effect. It is understandable that the design of the heat dissipation duct fully considers the efficiency of air flow to ensure that heat can be effectively taken away. The duct may be straight or curved to maximize the coverage area of air flow.
[0044] The heat dissipation component ensures that all key components, especially the energy storage module 3, operate at the optimal temperature. The heat dissipation component can be either air-cooled or water-cooled.
[0045] Specifically, when using an air-cooled structure, a heat sink made of metal materials (such as aluminum) is used, and multiple fins are designed to increase the surface area and improve the heat transfer efficiency. A fan is used to increase air flow and accelerate the convection transfer of heat, thereby effectively removing heat from the heat sink. The advantages of this system are its simplified design and low maintenance requirements, especially for application scenarios where temperature changes are not extreme.
[0046] When it is a water-cooled structure, it includes a water pump, pipes and a radiator. The coolant absorbs heat when it flows through the heat source (such as the battery module), and is then pushed to the radiator by the water pump, where the heat is released to the outside, and then the cooled liquid is circulated back to the heat source. The efficient heat dissipation characteristics of the water cooling system make it particularly suitable for high load and compact space conditions, ensuring effective heat dissipation even under extreme working conditions.
[0047] Through the heat dissipation components, the roof-mounted wind-solar integrated vehicle power generation device can maintain stable and safe performance in various operating environments, ensuring long-term reliability and efficient energy management. It is an ideal auxiliary system for new energy vehicles.
[0048] As a further description of this embodiment, in order to achieve cooperation with the luggage rack of the vehicle, a mounting position is designed at the bottom of the box body 1 to ensure stability and minimize the impact on the aerodynamic characteristics of the vehicle.
[0049] In order to realize external discharge, at least one waterproof discharge port 9 connected to the BMS control board 5 is embedded on the box 1. The discharge port 9 is waterproofed by an end cover. In most cases, the discharge port has at least one DC output port and one AC output port to meet the needs of different uses. Correspondingly, in order to facilitate understanding of the power of the energy storage module 3 and the overall status of the device, in some embodiments, a waterproof display screen and waterproof buttons will be installed on the box 1.
[0050] In the further description of the box body, the box body 1 is generally injection molded using flame-retardant plastic, and the internal space of the box body 1 is sufficient to accommodate major components such as wind power generation components 2, energy storage modules 3, fixed photovoltaic panels and retractable photovoltaic panels, while allowing a reasonable layout to optimize performance and ease of maintenance.
[0051] In the specific description of the wind power generation component 2, the wind power generation component 2 is installed in the horizontal through-flow channel 6 of the housing 1 through a bracket. The horizontal through-flow channel 6 is designed with an air inlet and an air outlet. The air inlet section of the variable diameter design is trumpet-shaped to increase the air intake volume and wind speed, and improve the efficiency of wind power generation. In terms of specific structure, the wind power generation component includes blades and a generator. The blades are designed according to aerodynamic principles to maximize the efficiency of capturing wind energy, and are connected to the rotating shaft of the generator. When the blades rotate under the action of wind, the rotating shaft of the motor also rotates. This rotational motion drives the generator, which is responsible for converting mechanical energy into electrical energy.
[0052] In this embodiment, in order to reduce driving wind resistance when not in use, an electrically opened door 8 is installed at the air inlet.
[0053] It is important to note that the design and angle of the blades are precisely calculated to optimize efficiency, and the appropriate generator is selected to ensure that electricity can be generated even in low wind conditions. In addition, considering that cars are often exposed to various environmental conditions, the materials and construction of wind power generation components have good weather resistance and can withstand external factors such as rain, sunlight, and temperature changes.
[0054] As for the structure of the blades and the generator, since it is the prior art and is widely used, it will not be described in more detail here.
[0055] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
