  The larger battery capacities and the longer waiting and charging time of
electric vehicles (EVs) results in low utilization of charging stations (CSs).
This paper, proposes fuzzy logic weight based coordination (FLWC) scheme to
enhance the utilization of CSs. Each EV has an associated uncertain information
including stay time and the current state-of-charge (SoC). The fuzzy logic
controller (FLC) analyze these inputs and determines a weight value. The
proposed FLWC scheme then allocates CSs to the EVs according to the weight
values. The proposed scheme is simulated for 100 EVs and 5 CSs using Matlab.
The simulation result shows about 30% improvement in the average utilization of
CSs as compared to first-come-first-serve (FCFS) based scheme.
