1. 研究目的与意义（文献综述）

1.1 background and significanceof selected topics

with the rapid development of science and technology,automobiles have become an indispensable part of human life. the demand and useof automobiles is increasing. at the same time, the population and economic growth havemade humanity’s demand for energy more and more. it is not onlybecause petrochemical energy cannot be regenerated, but also the consumption ofresources is increasing. the world's energy shortage has caused many problems andeven wars. the emission of automobile exhaust gas also leads to many climateproblems. people's quality of life has received many influences fromenvironmental pollution, which has aroused the attention of all countries. new energy vehicleshave emerged as the times require, and pure electric vehicles that have no pollutionto the environment, low noise, high efficiency, simple structure, and easymaintenance have become the focus of research and development in variouscountries.

as a popularchoice for urban public transportation, pure electric passenger cars have theadvantages of large passenger capacity, sufficient space, simple structure, andlow maintenance and maintenance. therefore, all enterprises and governments arefocusing on the development of pure electric passenger cars, and pure electricpassenger cars have become an unstoppable development trend. the rise anddevelopment of tourism have made the demand for tourist buses more and more. energy-saving,environmental protection, and simple structure of pure electric tourist bus hasbecome the primary choice for all companies.
