Solar Energy Based Automated Electric Vehicle (EV) Charging Station
Electrical Vehicles (EV) are the future of transportation. The market of EV is growing rapidly worldwide. In Bangladesh, companies like Akiz Group, Niloy-Nitol, and Walton are investing in EV. With the growth of EV in Bangladesh, the charging station for EV will be inevitable in the forthcoming time. To serve this imminent need, we have designed an electrical model of an automated electrical vehicle (EV) charging station which is mainly powered by solar energy. If solar energy is not available (during the night or cloudy sky), it will take energy from the grid. Whenever we have excess generated energy from PV, it will be fed to the grid.
The features of this model are-
(1)In this model, we have kept an energy storage system. The battery(s) of this system will be charged only from solar energy. The battery(s) will never suck energy from the grid.
(2)After serving the EVs, the remaining generated energy will be stored in the storage system i.e. the model supply energy to the EVs as its first priority.
(3)After serving the EVs and storage batteries, the excess energy will be supplied to the grid.
(4)When solar power is not available, the model will first try to take energy from the storage system. If the storage system runs out, only then the model will take energy from the grid.
(5)Every charging port in this model has an inbuilt charge controlling system. The batteries will be charged up to 90% and discharged up to 20%. *In steady state, the THD of the model is around 1%. (Less than 5% is IEEE standard) We hope that our model will be a pioneer to minimize environmental pollution and fossil fuel dependency by spreading EV in Bangladesh.
