This paper proposes a fully automatic replacement power battery technology solutions for a large charging and swapping station currently serving the electric buses. Based on systems, various types of equipment information resource are integrated and video surveillance information is linked to achieve automatic electric buses for swapping electricity. Through the automatic guidance of vehicles, matching of batteries and automatic battery swap, the Internet of Things technology, it makes the electric vehicles, batteries and automatic sensors of chargers interconnected, and then to realize the whole station automatic for swapping electricity. Simultaneously, combined with in-depth analysis of the actual operation of the station, a set of standardized operational procedures and control strategies is developed. The results show that the technical solution can improve the service capacity filling station under the premise of both safety and efficiency.
