Electric Vehicle (EV) is one of the most preferred vehicles in the current era, as it causes less pollution in the environment when compared to conventional vehicles. The depleted batteries can be refueled using battery charging methods which are further classified as slow, fast and battery swapping methods. EVs wait in queues before they get into service due to long duration of its charging. Queuing theory is used to evaluate behavior of EV charging stations. In this paper, the main objective is to study the different queuing models (M/M) with finite system and infinite system capacity at Fast Charging Stations (FCS). Aspiration level model is used to determine the acceptable range for service. Such models alleviate the difficulty in estimating various costs associated with respect to charging stations. And hence plays a key role in designing battery charging stations in EV developing countries like India. The objective is to understand different queuing models associated with the EV charging station by considering the data of Beijing charging station for a particular private EV.
