Currently renewable energy sources are adopted and embraced in completely all field. Nowadays electric vehicle also coming to concerns of each and every company. All countries are trying to increase its efficiency and completely keep it connected to renewable energy. Due to this the option of solar energy is selected as it is easy to install on each and every geographical condition. The work in this research displace the photovoltaic based charging station for electric vehicles so that the voltage fluctuations and voltage sag can be minimized as possible. After this all the work is tried to optimize by different technique namely Whale and PSO. Fuzzy controller is used for optimization. All the results are calculated by MATLAB simulations and a discussed thoroughly.
