摘要：电动汽车，一直被看做是下一代汽车的发展趋势。作为电动汽车的“加油站”，充电桩建设的全方面开展，无疑会提供巨大的市场。同时，成品油价格上涨速度高于下降速度，终车主承受的是越来越高的油价，电动车可以代替部分汽油柴油的消耗，降低了这部分成本。毋庸置疑充电桩是新能源战略推进的终端市场，如能在现在抢占先机，对资本的盈利有较大好处。

Abstract: Electric Vehicles have been regarded as the development trend of the next generation of vehicles. As the "station" of electric vehicles, the comprehensive development of charging pile construction will provide a huge market. At the same time, the price of refined oil rises faster than it falls, so the car owners will bear higher and higher oil prices. Electric vehicles can replace part of the consumption of gasoline and diesel, reducing this part of the cost. There is no doubt that the charging pile is the terminal market promoted by the new energy strategy. If we can seize the opportunity now, it will be of great benefit.

1.市场概述 Market Overview

由于电动汽车每天需要补充大量电能，经营充电站就可以获得巨大的充电服务收益。相对于加油站，电能比较安全和方便，可在各地大量安装设置充电站。根据投资规模，小到社区慢速充电桩，大到公路快速充电站，单站经营，组网经营均可。

As electric vehicles need to supplement a large amount of power every day, the operation of charging station can obtain huge charging service revenue. Compared with the gas station, the power is more safe and convenient, and a large number of charging stations can be installed in various places. According to the scale of investment, from small to community slow charging pile, to highway fast charging station, single station operation, network operation also can be.
