电动汽车的电气驱动技术及其发展研究

Research on Electric Drive Technology and Its Development of Electric Vehicle

近年来,我国交通业的飞速发展,导致我国能源消耗危机和环境污染问题的加剧,但这也为电动汽车的诞生和汽车产业,以及能源安全和低碳经济的长足发展带来新的增长动力。为此,本文围绕电动汽车的电气驱动系统构成以及电动汽车发展的趋势进行分析,并围绕汽车行业中采用的电驱动技术进行研究,解读电动驱动系统对于新能源汽车动力总成的作用,并分析和比较几种商业化的电驱动系统。

In recent years,the rapid development of China's transportation industry has led to the aggravation of the Chinese energy consumption crisis and environmental pollution problems,but this also brings new growth impetus for the birth of electric vehicles and the automobile industry,as well as the rapid development of energy security and low-carbon economy.To this end,this paper analyzes the composition of the electric drive system of electric vehicles and the development trend of electric vehicles,and studies the electric drive technology adopted in the automobile industry,interprets the role of the electric drive system for the powertrain of new energy vehicles,and analyzes and compares several commercial electric drive systems.
