The V2G technology can not only alleviate the power grid voltage and frequency fluctuation caused by renewable energy and improve power grid’s efficiency, but also create benefits for the electric vehicle users. Consequently, the technology of Vehicle to Grid (V2G) is attracting people’s extensive attentions. The significance and the structure of the V2G system have been introduced in this paper. Two new interaction charging strategies of the electric automobile integrated with smart grid have also been introduced briefly, which are the distributed interactive strategy and the centralized interactive strategy. The designing of the bi-directional power detection system in the EVs integrated with smarter grid is mainly discussed. The detection system adopts Logic’s production of the dedicated electric energy metering chip CS5460A, which will provide a high accuracy in data collection, flexibility in control performance and a high cost performance, and is quite suitable for measuring bidirectional power in V2G system. It will make up for the deficiency of DC electric energy measurement system.
