Many cities in developing countries are facing serious air pollution problems. The pollutants emitted by traditional fuel vehicles, such as sulfur dioxide, nitrogen oxides, particulate matter, etc., pose great harm to human health and the ecological environment. Electric vehicles have almost zero exhaust emissions, which can effectively reduce air pollution and improve the living environment and health status of urban residents. The energy consumption cost of electric vehicles is much lower than that of fuel vehicles, and their components have less wear and maintenance, making them easier to maintain. For operating vehicles such as taxis and ride hailing services, it can save a lot of operating costs and improve economic efficiency. Providing more economical and convenient travel options for low-income groups is conducive to promoting social equity and improving the accessibility and convenience of public transportation.
