Can charge a DC fan
Vehicle auxiliary energy
The power of a traditional car is generally about tens of kilowatts, while the solar radiation power is at most 1kW/m2, and the current photoelectric conversion efficiency is less than 30%. Therefore, all traditional cars are driven by solar energy, which requires a receiving area of ??tens of square meters, which is obviously difficult to achieve. However, in traditional automobiles, solar energy can be used as auxiliary power to reduce the consumption of conventional fuels. Moreover, the degree of electricalization of modern automobiles has increased, and the power consumption of various auxiliary equipment has also increased sharply. The application in this area mainly has the following forms:
Solar energy is used as an auxiliary charging energy for car batteries
[3]
After installing the solar battery on the car, it can continue to charge the battery when the vehicle is not in use, so as to avoid over-discharge of the battery and save energy.
Japan''''''''''''''''''''''''''''''''s Okei University has designed a model called Luciole(firefly)The color of the concept car is like a firefly. This car has been exhibited in Beijing. There is a photovoltaic panel with a high conversion efficiency of nearly one square meter on the roof, which is used to assist in charging the 12-volt battery. When the 12-volt battery is fully charged, the 12-volt battery will charge Charge the main battery. When the battery is fully charged, this concept car can travel 800 kilometers.[2]
Used to drive fans and automotive air-conditioning systems
When a car is parked in the sun, the lack of air circulation in the car makes the car body a greenhouse for collecting solar energy, which causes the temperature inside the car to rise, releases a large amount of harmful substances in the car, and deteriorates the air quality inside the car. If the installation of solar energy devices, such as solar fans, etc., can provide fresh air and cool down the vehicle without energy consumption during parking, and ensure good air quality when the vehicle is on the road again.
A solar cell is arranged under the glass of the car sunroof. The solar cell is connected to the input end of the control unit, and the input end is connected to the temperature sensor of the vehicle air conditioning system. At the same time, the input end is also connected to the battery and the igniter. The solar cell under the glass absorbs solar energy, and the battery can be charged through the car sunroof control unit to ensure sufficient power for the battery and prolong the service life of the battery. The most direct benefit of solar sunroofs to consumers is that in the hot summer weather, when the car is stopped under the scorching sun, it can automatically adjust the temperature inside the car when there is no energy supply. The solar collector panel built into the sunroof relies on the electricity generated by the sun to drive the blower through the control system to introduce the cold air outside the car into the car, drive out the hot air in the car, and achieve the purpose of cooling down. When the driver and occupants open the door and sit on the seat, they will not feel the heat, sultry and unbearable. The air-conditioning system of the car can reduce the temperature in the car to a comfortable level in the shortest time. At the same time, the air condition in the car can be improved, and the frost on the front windshield in the car can also be reduced in winter. According to the data, the temperature in the cab of a car with solar sunroof is reduced by up to 20°C compared with a model without ventilation. Solar energy is used for power supply, energy saving and cooling, which effectively reduces the heat generated in the car“Island” Effect.[3]
