Description

Technical Field

[0001] The present invention belongs to the field of photovoltaic power generation, and in particular relates to a power generation system and a vehicle. Background Art

[0002] Currently, buses and tourist coaches, a key component of public transportation, are becoming increasingly versatile, featuring a wide range of advanced electronic devices, such as intelligent navigation systems, onboard entertainment systems, and comfortable air conditioning systems, all of which require power. Furthermore, the number of electronic devices carried by passengers continues to increase, from smartphones and tablets to laptops, which often require charging while the vehicle is in motion.

[0003] As a result, the number of electrical devices used by vehicles and their passengers has shown a rapid growth trend, which has led to a sharp increase in electricity demand. In the face of the growing electricity demand, the traditional solution is mainly to increase the power supply or improve the capacity of existing batteries. Increasing the power supply may involve complex modifications to the vehicle's power system, which is not only costly, but may also affect the overall structure and performance of the vehicle and even bring safety hazards. For example, the additionally installed power supply equipment may occupy the limited space in the vehicle, affecting the comfort of the ride; at the same time, there may also be problems with its compatibility with the vehicle's original power system, resulting in unstable power transmission, etc. In terms of increasing the capacity of existing batteries, although it can increase power reserves to a certain extent, it is limited by the battery technology itself. The current increase in battery capacity is limited, and large-capacity batteries are often accompanied by problems such as increased weight and extended charging time. This is not a perfect solution for the pursuit of efficient and convenient modern transportation.

[0004] Therefore, there is an urgent need to design a power generation system that can not only replenish energy for vehicles but also provide additional energy for electronic equipment, thereby solving the problem of electricity anxiety. Summary of the Invention

[0005] One purpose of the present invention is to provide an on-board power generation system and a vehicle, which can output high-voltage electricity and low-voltage electricity. The high-voltage electricity can supply energy to electrical equipment, and the low-voltage electricity can supply energy to electronic equipment, thereby providing electrical energy to power-consuming equipment with different voltage requirements, solving the long-standing and unresolved problem of electricity anxiety.

[0006] To achieve the above objectives, the specific technical solutions of a power generation system and a vehicle of the present invention are as follows: A power generation system comprising: Power generation glass, comprising a light-transmitting layer and a light-absorbing layer, wherein the light-absorbing layer is coated on one side of the light-transmitting layer and is used to provide electrical energy; A transformer module is electrically connected to the power-generating glass. The transformer module includes a low-voltage output unit and a high-voltage output unit. The low-voltage output unit and the high-voltage output unit are arranged in parallel. The low-voltage output module can provide low-voltage electricity for providing electrical energy for electronic equipment, and the high-voltage output module can provide high-voltage electricity for providing electrical energy for the power system.

[0007] Furthermore, the light absorbing layer is coated on the periphery of the light transmitting layer so that the central area of ​​the light transmitting layer can transmit light.

[0008] Furthermore, the light absorbing layer is provided on at least one corner of the light transmitting layer.

[0009] Furthermore, the light absorbing layer is made of cadmium telluride.

[0010] Furthermore, the voltage transformation module and the power generation glass are separately provided, and the voltage transformation module and the power generation glass are connected to each other through a wire.

[0011] Furthermore, the power generation system also includes an energy control module, which is respectively connected to the power generation glass and the voltage transformation module. The energy control module is used to receive the electric energy of the power generation glass and output the electric energy to the voltage transformation module at a first reference voltage.

[0012] Furthermore, the energy control module includes a second reference voltage and a third reference voltage higher than the second reference voltage, and the second reference voltage and the third reference voltage are both lower than the first reference voltage. The energy control module also includes a control unit. When the output voltage of the power-generating glass to the energy control module is greater than the third reference voltage, the control unit can reduce the output voltage of the power-generating glass to the energy control module; when the output voltage of the power-generating glass to the energy control module is less than the second reference voltage, the control unit can increase the output voltage of the power-generating glass to the energy control module.

[0013] Furthermore, the voltage transformation module further includes an energy storage module, which is connected between the energy control module and the voltage transformation module. The energy storage module can store and display the electrical energy from the energy control module.

[0014] Furthermore, the transformer module also includes a power conversion unit, which is arranged at the end of the low-voltage output unit and / or the high-voltage output unit, and is used to output stable low-voltage electricity and high-voltage electricity.

[0015] A vehicle comprises the above-mentioned power generation system.

[0016] The power generation system of the present invention has the following advantages: 1. This power generation system solves the problem of increasing the vehicle's power supply without affecting the vehicle's lighting, allowing various electrical equipment in the vehicle to operate more stably and efficiently.

[0017] 2. This power generation system solves the "battery anxiety" of passengers and drivers, so that people no longer need to worry about the power of electronic devices during travel.

[0018] 3. This power generation system is highly consistent with the concept of green travel. It does not produce any pollutants or greenhouse gases during the power generation process, realizes the clean use of energy, reduces carbon emissions, and contributes to environmental protection.

[0019] The vehicle of the present invention has the following advantages: 1. The vehicle uses power-generating glass to provide electricity, which has the advantage of high power generation efficiency. In addition, during the driving process of the vehicle, it makes full use of the sunlight received by the roof, windows and other parts to convert solar energy into a steady stream of electricity, effectively filling the electricity gap.

[0020] 2. The vehicle sets the light-absorbing layer at the edge of the light-transmitting layer, so that the overall light transmittance of the power-generating glass is relatively high. While generating electricity efficiently, it will not affect the lighting of the vehicle, ensuring a bright and transparent environment inside the vehicle, realizing energy conversion, and isolating indoor and outdoor heat.

[0021] 3. The vehicle can be charged conveniently while passengers are on board, eliminating the need to carry a power bank. This alleviates the inconvenience of being unable to make payments, communicate, or entertain due to a dead mobile phone. It is especially beneficial for long-distance commuters and tourists, enhancing the attractiveness and competitiveness of public transportation.

[0022] 4. Without changing the existing body structure, the vehicle only replaces the glass on both sides of the body with power-generating glass. By making limited adjustments to the line layout, it can achieve the ability to supply power at low voltage. If it is a new energy vehicle, it can also achieve the ability to supply power at high voltage and store electrical energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Those skilled in the art will appreciate that although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0027] Please refer to the attached Figure 1 To the attached Figure 5 A power generation system and a vehicle according to the present invention are described.

[0028] Figure 1 This is a schematic structural diagram of the power generation glass 1 of this embodiment; Figure 2 Schematic diagram of the structure of the light-transmitting layer 12 of this embodiment; Figure 3 Schematic diagram of the structure of the power generation system of this embodiment.

[0029] This embodiment provides a power generation system, such as Figure 1-3 As shown, the power generation system includes a power generation glass 1 and a transformer module, wherein the power generation glass 1 includes a light-transmitting layer 12 and a light-absorbing layer 11, the light-absorbing layer 11 is coated on one side of the light-transmitting layer 12, and the light-absorbing layer 11 is used to provide electrical energy; the transformer module is electrically connected to the power generation glass 1, and the transformer module includes a low-voltage output unit and a high-voltage output unit, and the low-voltage output unit and the high-voltage output unit are arranged in parallel. The low-voltage output module can provide low-voltage electricity for providing electrical energy for electronic equipment, and the high-voltage output module can provide high-voltage electricity for providing electrical energy for the power system.

[0030] It is understandable that electronic devices generally refer to mobile phones, tablets and even laptops held by passengers, and the power system generally refers to the lights, air conditioners and other structures on new energy vehicles.

[0031] It can be understood that the power generation system of this embodiment has the following advantages: 1. This power generation system solves the problem of increasing the vehicle's power supply without affecting the vehicle's lighting, allowing various electrical equipment in the vehicle to operate more stably and efficiently.

[0032] 2. This power generation system solves the "battery anxiety" of passengers and drivers, so that people no longer need to worry about the power of electronic devices during travel.

[0033] 3. This power generation system is highly consistent with the concept of green travel. It does not produce any pollutants or greenhouse gases during the power generation process, realizes the clean use of energy, reduces carbon emissions, and contributes to environmental protection.

[0034] Furthermore, the light-absorbing layer 11 is applied to the periphery of the light-transmitting layer 12, allowing light to pass through the central area of ​​the light-transmitting layer 12. By placing the light-absorbing layer 11 around the periphery of the light-transmitting layer 12, light can be transmitted through the central area of ​​the light-transmitting layer 12, preventing excessive coverage of the light-absorbing layer 11 that would affect vehicle lighting. This ensures a bright and transparent environment inside the vehicle, achieves energy conversion, and isolates heat from both indoors and outdoors.

[0035] In this embodiment, if Figure 2 As shown, the shape of the above-mentioned power generation glass 1 is rectangular. It can be understood that the shape of the above-mentioned power generation glass 1 can also be replaced by diamond, triangle, or even circle, etc., which is not specifically limited here.

[0036] Furthermore, the light absorbing layer 11 is provided on at least one corner of the light transmitting layer 12 .

[0037] Those skilled in the art will understand that the control structure of the power generation system is generally not set on the glass, but is connected from the corners of the glass to facilitate the routing of the power generation system and avoid safety problems caused by excessive pulling of the wires. Therefore, in this embodiment, the light-absorbing layer 11 is set on at least one corner of the light-transmitting layer 12. When it is necessary to control the lead-in of the power generation glass 1 to control the system, the corner position of the power generation glass 1 with the light-absorbing layer 11 can be selected as the starting point. On the other hand, since the power generation glass 1 needs to have at least one corner, from the perspective of routing, the circular glass is usually set on the frame, and its routing method is still around the frame. That is to say, in actual application, the staff can select the appropriate shape of the power generation glass 1 and the appropriate coating method of the light-absorbing layer 11 according to actual needs, and no specific limitation is made here.

[0038] Those skilled in the art will appreciate that cadmium telluride generally has higher conversion efficiency than traditional silicon-based photovoltaic panels, especially under low-light conditions. Cadmium telluride can be manufactured in thin film form, making it lightweight and easy to install and transport. Cadmium telluride thin films can be coated on various substrates, including glass, metal sheets, and plastics, enabling applications in areas such as building integration. Cadmium telluride also has a good temperature coefficient, meaning its performance degrades less at high temperatures. Therefore, in this embodiment, the light-absorbing layer 11 is made of cadmium telluride.

[0039] As a preferred embodiment, the power-generating glass 1 adopts a stacked design of P-type single crystal silicon and cadmium telluride thin film. The light-transmitting layer 12 is set to a PERC single crystal silicon wafer with a specification of 156×156mm², and a 2μm cadmium telluride thin film is deposited on the surface as the light-absorbing layer 11. When photons hit the light-absorbing layer 11, electrons jump to the conduction band to form free electron-hole pairs. An electric field will be established inside the light-absorbing layer 11, causing the two to separate and move in a directional manner, thereby forming a photocurrent, with electrons moving to the negative electrode and holes moving to the positive electrode, accumulating to generate voltage.

[0040] Specifically, the voltage transformation module and the power generation glass 1 are separately provided, and the voltage transformation module and the power generation glass 1 are connected to each other through a wire.

[0041] Figure 4 Schematic diagram of the structure of the first embodiment of the power generation system.

[0042] Further, if Figure 3 and 4 As shown, the power generation system also includes an energy control module, which is respectively connected to the power generation glass 1 and the transformer module. The energy control module is used to receive electrical energy from the power generation glass 1 and output electrical energy to the transformer module at a first reference voltage.

[0043] It can be understood that the energy control module is used to monitor the voltage formed by the power-generating glass 1 in real time to prevent overcharging and over-discharging and protect the safety of the system. In addition, the energy control module of this embodiment can also directly display the power generation power of the solar glass, the voltage of the energy storage battery, the charging current and the working status of the load.

[0044] Specifically, the energy control module includes a second reference voltage and a third reference voltage higher than the second reference voltage. The second reference voltage and the third reference voltage are both lower than the first reference voltage. The energy control module also includes a control unit. When the output voltage of the power-generating glass 1 to the energy control module is greater than the third reference voltage, the control unit can reduce the output voltage of the power-generating glass 1 to the energy control module; when the output voltage of the power-generating glass 1 to the energy control module is lower than the second reference voltage, the control unit can increase the output voltage of the power-generating glass 1 to the energy control module.

[0045] It is understood that the energy control module can also be implemented using technical means available to those skilled in the art. For example, Publication No. CN108028533A discloses a hybrid solar power control system, which includes an energy control module and an energy controller. The energy control module unit is connected to a photovoltaic power source and another power source, and includes circuits for connecting input photovoltaic power source and other power sources, combining energy from one or more power sources for direct current (DC) output, and switching between the power sources based on the available input energy from each power source. For another example, publication number CN119154348A discloses a new energy power generation and energy storage control system, which includes an energy storage unit for storing electrical energy; an energy control unit for monitoring the status of the energy storage unit and providing battery balancing, overcharging and over-discharging prevention functions; an energy conversion unit converts the direct current output by the energy control unit into alternating current through a PWM pulse width modulation method; and an energy management unit for predicting energy production and consumption, and optimizing energy storage and energy release strategies through a linear programming optimization algorithm.

[0046] It can be seen that the above energy control module can be implemented and applied by those skilled in the art based on the existing technology, and can achieve the function of controlling the input voltage and the output voltage.

[0047] Preferably, the control unit adopts a DSP28335 main control chip and integrates an MPPT algorithm, wherein the MPPT algorithm is a perturbation observation method superimposed on an incremental conductance hybrid algorithm, ensuring that the overall conversion efficiency is higher than 98%.

[0048] In this embodiment, the first reference voltage is 48V, the second reference voltage is 28V, and the third reference voltage is 36V. That is, the energy control unit is used to control the voltage from the power generation glass 1 between 28V-36V and output it at a voltage of 48V.

[0049] Furthermore, the voltage transformation module also includes an energy storage module, which is connected between the energy control module and the voltage transformation module. The energy storage module can store and display the electrical energy from the energy control module.

[0050] The energy storage module of this embodiment includes an LTC2945 coulomb meter to monitor the charge and discharge current in real time. The coulomb meter has a range of ±30A and an accuracy of ±0.5%. The voltage measurement range is 0-36V with a resolution of 1mV. The temperature compensation crystal oscillator is ±2ppm, thereby ensuring the accuracy of the time base.

[0051] In addition, the power calculation model of this application adopts an exponential decay model, that is, ,in, is the initial current, For leakage current, the above exponential decay model is adjusted to: By real-time monitoring of the amount of electricity passing through the battery during charging and discharging, that is, by integrating the amount of electricity flowing into (charging) and out of (discharging) the battery, we can accurately know how much power is left in the battery, avoiding the inaccuracy of traditional voltage detection methods (voltage will be affected by factors such as temperature and battery aging) and causing errors in the power display.

[0052] Furthermore, the transformer module further includes a power conversion unit, which is provided at the end of the low-voltage output unit and / or the high-voltage output unit, and is used to convert direct current into alternating current.

[0053] Figure 5 Schematic diagram of the structure of the second embodiment of the power generation system.

[0054] Specifically, if Figure 5 As shown in the figure, the power conversion unit includes a rectifier and an inverter. The rectifier adopts synchronous rectification technology, that is, it uses IRF3205 MOSFET, the filtering parameters are 10mH / 35A, and the ripple voltage is less than 100mVpp; the inverter adopts a full-bridge topology, SPWM modulation, and a carrier frequency of 20kHz, which is used to output 220V / 50Hz AC power.

[0055] This embodiment also provides a vehicle, comprising the above-mentioned power generation system.

[0056] It can be understood that the vehicle of this embodiment has the following advantages: 1. The vehicle utilizes power-generating glass 1 to provide electricity, which has the advantage of high power generation efficiency. In addition, during the driving process of the vehicle, it fully utilizes the sunlight received by the roof, windows and other parts to convert solar energy into a continuous supply of electricity, effectively filling the electricity gap.

[0057] 2. By arranging the light-absorbing layer 11 at the edge of the light-transmitting layer 12, the overall light transmittance of the power-generating glass 1 is relatively high. While generating electricity efficiently, it does not affect the lighting of the vehicle, thus ensuring a bright and transparent environment inside the vehicle, realizing energy conversion, and isolating indoor and outdoor heat.

[0058] 3. The vehicle can be charged conveniently while passengers are on board, eliminating the need to carry a power bank. This alleviates the inconvenience of being unable to make payments, communicate, or entertain due to a dead mobile phone. It is especially beneficial for long-distance commuters and tourists, enhancing the attractiveness and competitiveness of public transportation.

[0059] 4. This vehicle does not change the existing body structure, but only replaces the glass on both sides of the body with power-generating glass 1. By adjusting the circuit layout in a limited way, it can achieve the ability of low-voltage power supply. If it is a new energy vehicle, it can also achieve the ability of high-voltage power supply and energy storage.

[0060] Furthermore, the vehicle uses whole-vehicle system integration and monitoring. The distributed control system adopts a CAN bus network architecture with a baud rate of 500kbps. The monitoring node configuration includes photovoltaic arrays and energy storage batteries. Among them, the photovoltaic array adopts one monitoring point for every 2m² to collect voltage, current and temperature, etc. The energy storage battery adopts one BMS slave control module for every four cells; the human-machine interface adopts a 7-inch TFT touch screen, and the display parameters include: the refresh rate is set to 60Hz, and the instantaneous power generation power is 0.1W, so as to monitor the situation inside the vehicle in a timely manner.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
