The battery car is also called an "electric car". It is a pure electric vehicle powered by a battery (battery) and driven by an electric motor (DC, AC, series excitation, and separate excitation). In recent years, it has been widely popularized in our country.
At present, domestic battery cars are mainly used for sightseeing and carrying passengers, public security patrols, and transporting goods. The main purpose of electric sightseeing cars is to carry passengers in parks, scenic spots, leisure resorts, universities, hospitals, golf courses, real estate companies and other places. The main purpose of electric patrol vehicles is to conduct public security patrols in station squares and crowded places. The main use of electric patrol vehicles is in factories, ports, and logistics warehouses. The main purpose of the electric sanitation vehicle is to clean up the site, clean the road surface, and transfer garbage. The service life of the battery car is generally 8 to 12 years, and the service life of the battery is generally 1-4 years (depending on the use and maintenance)
A brief history
The development history of battery cars: Originated in the 1880s, used as private cars, trucks and urban public transportation vehicles. The low speed and limited charging range of the battery car are not disadvantages, and its advantages such as no noise and low maintenance cost make it popular. Before 1920, battery cars had been competing with gasoline cars. Later, the number of battery cars began to decrease, because electric starters made gasoline-powered cars more attractive, and mass production reduced the cost of gasoline cars. In Europe, electric vehicles have been used as short-haul freight vehicles. Beginning in the 1970s, countries have renewed interest in electric vehicles, especially because they should not rely on foreign oil and environmental issues, which have led to repeated improvements in the speed and driving distance of battery vehicles. As automobile energy and pollution issues continue to attract people's attention, the continuous improvement of battery car technology and the continuous expansion of use, the future development of battery cars has a bright future.
Development status
The development of the 21st century can be described as an era of "calling for green and environmental protection". It not only requires people to focus on energy conservation, but more importantly, requires people to pay more attention to the living environment and green environmental protection in order to achieve sustainable social development. Electric vehicles are the only vehicles in the world that can achieve zero emissions. Due to the requirements of environmental protection, coupled with the development of new materials and new technologies, electric vehicles have entered a period of rapid development.
China's oil resources are relatively poor, and fuel and exhaust emissions will be the main sources of air pollution in large and medium-sized cities in the future. For this reason, the development of electric vehicles in China is undoubtedly the inevitable trend of future development, and it is also in line with the needs of the green revolution. Because electric vehicles are environmentally friendly and have low energy consumption, they are the best transportation product for green environmental protection and air pollution. Provide a good ecological environment, make it healthy physically and mentally, and have a good living environment. The development of the electric vehicle industry is adapted to this trend, and it is a tool for sustainable social development.
As a green vehicle, electric vehicles will bring tremendous changes to human society in the 21st century. Conforming to the current general trend of international scientific and technological development, taking electric vehicles as China's entry point into the 21st century automobile industry is not only a strategic choice to realize the technological leapfrog development of China's automobile industry, but also an important choice to realize the sustainable development of China's automobile industry.
In 2013, the Twelfth National Games was held. The National Games Village Organizing Committee chose the battery car provided by Yuejin Zijin (Tianjin) Electric Vehicle Co., Ltd. to provide transportation services for the National Games Village. In response to the National Games' environmental protection concept of "green environmental protection, energy saving and emission reduction". It can be seen that while the battery car contributes to environmental protection in China, it also conforms to the current development trend.
