1. Overview:

With the enhanced awareness of environmental protection, the support of new energy vehicles from all over the world, new energy vehicles will occupy an important position in automotive market in the future , if you are going to say the support for the charging station system is not complete which limits the development of electric vehicles , then this issue is being gradually resolved. State Grid and China Southern Power Grid were invested heavily in building electric car charging station and charging pile associated with the new energy automobile accessory charging facilities, along with two National Grid plans to develop large-scale construction in the electric vehicle charging station and charge pile, electric vehicle charging station construction has entered the fast lane.

Charging pile application:

Electric car charging pile has the following characteristics: with measured points but scattered, wide coverage, far communication distance. And with the development of the city, the network topology is required to have the flexibility and scalability in structure,therefore, the electric car charging pile communication mode selection should consider the following questions:
1) The reliability of communication - communication systems have to withstand the long-term harsh conditions and strong electromagnetic interference or noise interference, and maintain communications.
2)The construction costs -meet the reliability you should consider the construction costs and long-term use and maintenance costs.So wireless is your best choice.
3)The two-way communication - not only can upload information , but also to release controlled amount.
4) The multi-service data transfer rate - With the growing of terminal business, the master station to the sub-stations, sub-stations to the terminal communication increase the demand on multi-service data transfer rate multiple services
5) The flexibility and scalability of communication - the charging pile has many points, wide coverage and dispersed characteristics so it needs a standard communication protocol, with the development of "ALL IP" network technology trends and the grows of electric power operations ,IP bearer needs to consider ,also ask for easy installation , construction, commissioning, operation and maintenance.
