solar electric car

technical field

The utility model relates to the technical field of solar power generation, in particular to a solar electric vehicle.

Background technique

With the improvement of consumption level, automobiles have almost become a necessary means of transportation for every family, and some families even own several cars at the same time. Since the current automobiles generally use gasoline, diesel or natural gas to provide power, with the substantial increase in the number of automobiles, the energy consumed is very huge, and automobiles burning gasoline and diesel are an important source of pollution in cities. Exhaust gas including sulfur dioxide and nitrogen oxides will pollute the air and affect people's health. From the perspective of protecting the environment, on the basis of traditional vehicles, electric vehicles have been introduced, such as electric cars, electric tricycles, electric bicycles, etc. Electric vehicles are powered by vehicle-mounted power supplies. Electric vehicles themselves do not emit harmful gases that pollute the atmosphere, and can make full use of the surplus electricity at night when the electricity consumption is low. Therefore, electric vehicles, especially electric vehicles, are already environmentally friendly widely promoted and used.

However, electric vehicles require a large amount of power supply, and currently the main electricity in major cities comes from the combustion of fossil fuels. Although electric vehicles use electricity as power, it is equivalent to indirectly increasing the waste emitted by power plants, so it will also It consumes a lot of energy, and because the electric vehicle is powered by a battery, when the electric energy stored in the battery is exhausted, the electric vehicle cannot continue to drive. At this time, it must go to a dedicated charging station for charging, but if there is no dedicated charging station nearby If there is no station, the electric vehicle cannot be charged in time, causing the electric vehicle to be unable to continue to be used.

Based on the above reasons, people have developed electric vehicles using solar energy as energy. A solar power generation device is installed on the electric vehicle to convert solar energy into electric energy, and the electric energy converted by solar energy is used to charge the battery, so that the electric vehicle can continue to run. Since solar energy is an inexhaustible clean energy and renewable energy, using solar energy to power electric vehicles can greatly reduce the consumption of non-renewable energy (such as coal) and reduce or even eliminate environmental pollution .

However, the solar modules in the solar power generation devices of most electric vehicles are usually ordinary solar panels, which are relatively simply installed on the body surface of the electric vehicle. The sunlight utilization rate of the battery panel is low, therefore, the electricity generated by the solar energy is less, which makes the battery life of the electric vehicle insufficient.
