The customer, end minimization process of charging cost for electric vehicles (EVs), and the increased electric vehicle fleet caused by uncertainties are the main factors to the degradation of the reliability of the distribution system. Moreover, the Vehicle-to-grid feature consideration is the major asset for discharging the EV at peak demand leading to customer satisfaction towards the economic savings of expenses (charging bills). In this paper, the reliability probability method and the failure rate evaluation have been implemented for the charging ports involved in the charging station of the 50-350 kW power distribution system. The failure rate of the 24 and 12 charging ports involved parking lot has been considered for the reliability analysis. The failure rate evaluation of the system has been estimated with an expected failure rate of 2%. The maintenance cost of the charging port has been evaluated on the basis of the regular failure rates in the charging system. The maintenance cost of the fuel system and EV charging system has been compared with consideration of efficiency. The Binomial distribution probability method is applied in this paper. It is inferred that the applied method is suitable for the estimation of failure rates of charging stations that are installed with the strategy of the batched porting system. [ABSTRACT FROM AUTHOR]
