EV Charge Station System Reliability Modeling and Analysis 2017-01-0198

Component failures in electrical vehicle (EV) charge stations may lead to a complete loss or reduction of charging power available to the vehicles. The multistate coherent structure is employed to model the system reliability and availability of the charging cabinet and station. The number of vehicles and the customer behavior in choosing charge port is considered in the analysis. The methodology is illustrated with a simplified charging cabinet example. The usefulness of the methodology presented in this paper to EV charge station design and service is further discussed. In summary, the framework of a multistate system reliability modeling is developed for EV charge station, which can be used for further studies. The authors believe it can find many engineering applications in EV charge station and beyond.
