Description

A high-power solar intelligent hybrid vehicle

technical field

The utility model relates to the manufacturing field of solar intelligent hybrid vehicles, more specifically, relates to a high-power hybrid vehicle powered by solar power and gasoline.

Background technique

With the rapid growth of the world economy and population, people's demand for oil and other resources is increasing. Traditional fossil fuels are facing the danger of depletion. At the same time, the use of petroleum and other resources will inevitably bring about environmental pollution. In order to create a sustainable development environment for future generations, we urgently need to develop a new "clean" car . As an ideal traditional vehicle to replace all-fuel vehicles, hybrid vehicles have their inherent advantages. The air pollution in large cities in my country can no longer be ignored. Vehicle emissions are one of the main sources of pollution. 16 cities in my country have been included in the global air pollution list. Among the 20 worst cities. my country's current per capita car is 10 cars per 1,000 people, but oil resources are insufficient, and tens of millions of tons of oil have been imported every year. With economic development, if China's per capita car holdings reach the current global level-every 1,000 people have 110 cars, my country's car ownership will increase by 10 times, and oil imports will become a big problem. Therefore, the research and development of solar hybrid vehicles in our country is not a temporary short-term measure, but a significant and long-term strategic consideration. China's automobiles have entered the oil-free era, and there are many development directions for oil-free new energy vehicles, but one of them is hydrogen fuel cell technology, which is immature and expensive, and will be a technology 20 years later. In January 2007, Dr. Menahem Anderman, an expert on automobiles and power batteries, made this conclusion when he testified before the US Senate Energy and Resources Committee. China also does not have the platinum necessary for hydrogen fuel cell reactions. Although there is no public statement, it is rumored that the country's internal decision-makers have made it clear that China is not suitable for the development of hydrogen fuel cell vehicles, and it is only a scientific research follow-up project. In addition, as far as technologies that mainly use low-cost liquid fuels such as methanol and ethanol are used, due to the large-scale use of corn and grains as raw materials, global food prices continue to rise, and this is unlikely to become China's technology choice. There is also a clean diesel fuel technology, that is, diesel with low sulfur content (diesel with a sulfur content lower than 350ppm), using energy that can save power by an average of 30% compared with gasoline engines. However, due to the poor quality of domestic diesel, frequent oil shortages always start with diesel, and diesel is not supported by national policies. From the perspective of technological maturity and China's national conditions, solar hybrid vehicles should be vigorously promoted. The advantage of solar hybrid vehicles is that they retain the lifestyle of traditional gasoline vehicles, and use solar power and vehicle engines to generate electricity for battery packs. Charging, the engine and the electric motor automatically switch the power mode through the intelligent control device, so that the hybrid vehicle can run on the road quickly, efficiently and energy-saving. Depending on the degree of mixing of the gasoline engine and the electric motor, the number of charging times is equivalent to the number of refueling times of a traditional gasoline car, or no charging is required. The high-power and high-efficiency solar panel on the roof of the car generates power for the battery pack, and the driving distance of the car is not limited. Solar hybrid vehicles save gasoline consumption and reduce carbon dioxide emissions. It is of great significance to replace traditional energy vehicles with high-power solar intelligent hybrid vehicles, which have changed the traditional energy power model of automobiles. Under the call for energy conservation and emission reduction under the environmental issues of global concern, as a high-tech enterprise that produces and manufactures new energy products, it is necessary to make due contributions to the country and society, so as to reduce the air pollution caused by traditional energy vehicles and energy consumption. Problems such as shortage will be solved by utilizing new energy sources.

Existing hybrid electric vehicles have the following disadvantages: 1. Existing hybrid electric vehicles all adopt gasoline power and other energy-powered automobiles, but the two energy sources are all independently controlled and manually switched; 2. Existing hybrid electric vehicles Power vehicles use gasoline power and hydrogen fuel cell vehicles, which are immature in technology and high in cost; 3. The battery packs in existing hybrid vehicles use ordinary lithium batteries, which have small energy storage capacity and short service life; 4. Existing The charging of the battery pack in the motor part of the hybrid electric vehicle can only be charged by the mains, and the charging time is long and the cruising distance is short; Poor; 6. Traditional solar electric vehicles use conventional solar modules, which have low conversion efficiency and take a long time to charge the battery pack.
