Abstract: Electric drive has become one of the important trends in the future transformation and development of the automobile industry, and the sales volume of pure electric new energy vehicles in China is growing rapidly. This paper takes the sales volume of pure electric vehicles in China from 2016 to 2020 as the original data, and forecasts the sales volume of pure electric vehicles in China from 2021 to 2025 by constructing the grey prediction model GM(1,1). It is found that the sales of pure electric vehicles in China will continue to rise from 2021 to 2015, and the sales of pure electric vehicles in 2025 will reach 2.308 million. The gray prediction model can accurately predict the development trend of pure electric vehicles in China, and can provide a certain reference for the government to formulate subsidy policies, promote pure electric vehicles, and enterprises' research and development, production and sales.
