The current research on electric vehicle

In 21st century, Electric vehicle(EV) as a green transportation tool, EV has won great attention from researchers, leading to a series of intensive and extensive studies. With the development of high-storage battery and EV, the number of the EV will rise dramatically, so that the random charging and discharging behavior will bring new challenges to safe and stable operation of power grids. The paper introduces briefly some aspect of EV, including studies on the government policies, charging methods, key techniques, impacts of charging, and solutions to the related issues. Based on the current development status and problems, discuss the trend of EV.
