Most industrial enterprises only have extensive production mode and lack of certain economy. Combined with the characteristics of renewable energy power generation system and electric vehicles, a mathematical model of electric vehicles with wind power and photovoltaic power generation station was firstly built, and then an industrial enterprise energy efficiency optimization management model with electric vehicles charging station was built on this model. Improved adaptive genetic optimization algorithm is programmed based on MATLAB 7.0. Then taking a certain system as an object, we optimize the energy efficiency of industrial enterprises in 5 typical scenarios. The results show that the reasonable utilization of renewable energy power generation and electric vehicle charging load can significantly improve the energy efficiency of industrial enterprises.
