Trend Analysis of Electric Vehicle's Power Consumption Based on EV-TEST

Abstract

In the context of the rapid development of electric vehicles, various new energy vehicle companies are promoting technological upgrading of products. High efficiency of power system, lightweight body and parts are its main development trend. In order to analyze the technical level of electric vehicle power consumption, this paper analyzes the technical level of three batches of vehicles mainly from three aspects: power consumption, temperature adaptability and power performance based on the test results of 21 EV-TEST models. The results show that after one year of technology development, the energy consumption has been reduced by about 9.9%; The temperature adaptability in high temperature environment is increased by 40.9%. The temperature adaptability in low temperature environment has been increased by 25.3%; The power performance has been improved by 11.3%. It shows that with the progress of technology, electric vehicles are developing in the direction of low energy consumption and high performance.
