With the growth of electric vehicles across the globe, it is essential to have a corresponding charging infrastructure developed. Several research works highlight the benefits of aggregator-based scheduling, where all aggregators operate in similar conditions with the same amount of purchased energy. However, there are unscheduled EVs left due to unavailability of sufficient energy and/or charging slots. This paper presents a multiaggregator-based charge scheduling scheme that incorporates collaborative charging and realistic situations with variable energy purchase (VEP) and cancelation charges. VEP reflects a practical situation where the aggregator purchases energy based on average scheduling requests per day. Similarly, customers are penalized for not arriving at the scheduled slot. The charge scheduling problem is addressed from the aggregator point of view, wherein the total profit and the number of scheduled EVs are maximized. With VEP, a greater number of EVs were scheduled through collaboration and overall profits were observed to be higher than with equal energy purchased. The implementation of cancelation charges on the customer further resulted in an increase in the profits.
