The study of distributed EV charging station based on network

In order to reduce carbon emission, the world wide is developing novel electrical vehicle (EV) application. The battery and charging technology development is the most difficult breakthrough for EV promotion, wherein the design of convenient and reasonable charging station is critical to implement a sound charging system. This paper firstly introduces the development of Hongkong local charging station, and then proposes the distributed charging station network based on communication hierarchy. Finally, the state of charging (SoC) evaluation based on hybrid mode is presented. The deployment of charging station network testified distributed charging station network can effectively provide electricity to EV and centralized monitor the charging state. In the future, the proposed charging station network will has a broad application in Hong Kong market.
