This paper conducts an investigation on the operating cycle of Bus No. 306, which is equipped with wireless charging system, in Changsha, Hunan Province, China. The wireless charging system and electric buses are produced by ZTE Corporation (Zhongxing Telecommunication Equipment Corporation) and BYD Company Limited, respectively. In this paper, the operating cycle is divided into two parts, operation process and charging process. The real-time bus route and SOC (state of charge) during daytime operation are recorded with the help of GPS (global position system) and BMS (battery management system). The wireless charging process is tested with a power analyzer and compared with that of a plug-in electric bus. Besides, the radiation level while charging is also taken into consideration. Currently, the buses are designed to operate in daytime and get charged at night. In order to lower battery cost and enhance the full-cycle efficiency, a new operating strategy is proposed and validated based on experimental studies. As a result, extra charge time is introduced to daily operation so that the rated battery capacity can be reduced benefit from additional charging processes.
