Design of waiting time Perception System in charging station based on Internet of things

In order to improve the charging service quality of electrical vehicles (shorted as EVs) , it is necessary to provide waiting time information in charging station for EV users, in order to ensure their time schedule better and their time utilization more efficiently. Therefore, based on Internet of things, firstly, from the designated waiting area of the charging station, the information needed to be collected are analyzed, and the appropriate sensing modes are selected; secondly, based on the analysis of waiting time composition, an information perception system is designed to obtain the accurate waiting time in charging stations; finally, according to the charging curves of batteries, capacitor is used as simulated component. The working process of the charging waiting time which is based on MSIC (Medium scale integrated circuit) is simulated by Proteus.The results show that the designed perception system can satisfy the expected requirements.
