Energy and the environment have become the most current concerns in the world, and many countries have considered developing electric vehicles as an important means to solve the problem of energy and the environment. So, it is very necessary to research the effect on grid by electric vehicle charge and discharge but it must build a suitable model of batteries of electric vehicle. This paper built a PNGL and Thevenin simulation model, and compared the simulation curve with the actual measure curve. The results prove that the two methods on two occasions applications are more appropriate.
