However, compared with the conventional fuel vehicle, the largest pain point of the new energy vehicle is that the energy supplementing efficiency is too low, and the reasons are two: firstly, most new energy vehicles on the market currently have energy compensation schemes that charging is carried out through charging piles, the charging process is long in time consumption and low in efficiency, and the new energy vehicles are far less convenient to use than fuel oil vehicles; secondly, the quantity of the charging piles on the current market is too small, so that the huge charging demand of the new energy vehicle is difficult to meet, and the current charging piles have no unified standard due to the fact that the new energy market is a new market and the technology and development routes are immature.
