Abstract: In recent years, the new energy industry has developed rapidly. People began to understand that new energy has derived a large number of industries, such as the popularity of new energy vehicles everywhere. As the only medium to supply energy, charging pile has a decisive impact on the development of new energy vehicle industry. Nowadays, the charging efficiency of new energy charging piles is low, the charging speed is slow, and there are few charging piles, which can not well meet the needs of new energy vehicle owners. Above all, this article introduced the development of new energy cars, and then illustrated the current situation of charging piles, the existing problems of new energy charging piles are listed and then discusses the feasibility and improvement methods of new energy charging pile, so as to make the new energy industry develop more smoothly. Finally, we imagine the future of new energy charging piles and it provides a reference for the construction of charging pile of new energy vehicles.
