Abstract
With the emerging development of electrical vehicles (EVs) in transportation, the utilization manufacturing companies are concentrating on the development of charging facilities for customers. Maintaining the reliability of charging ports is a difficult task for the intermediate charging conditions of EVs, even though the charging station industries are installing the charging stations as per the specifications of the distribution system. To improve the reliability of the charging station for the distribution system, the 12 and 24-ported configurations have been proposed and systems have been designed with the individual batch structure. The performance analysis of the proposed non-uniform configurations has been estimated in terms of reliability as per the failure rate of the individual port in batch. The proposed 12 and 24-ported configuration’s failure rate has been evaluated with the standards of MILHBK-217 F. According to the failure rate of the port, the evaluation process has been introduced to find the success rate of the charging station. The maintenance cost has been estimated based on the failure and success rate of the proposed 12 and 24 systems. Finally, the performance analysis of the proposed 12 and 24-port configurations comparison has been estimated in terms of failure rate, success rate and maintenance cost. In this work, the binomial distribution probability technique has been implemented for the appropriate failure rate estimation of the charging station. The proposed 12 and 24-port non-uniform configurations are capable of providing reliable operation and are implementable for the low area of the plinth for EV charging stations.
