Abstract:
Renewable sources of energy is getting more attention currently for sustainable environment. The
clean energy sources contribute extensively in the mitigation of harmful emission and climate
change. To fulfill this demand, transportation electrification is the need of time. In order to
decarbonize the transport sector Electric vehicles (EVs) demand has increased globally. It is
proposed that by 2040, there will be 35- 47% Electric Vehicles on the roads. However, the EVs‟
growth is contained by one of the main hindrance i.e. the longer charging time. Due to this,
burden on electrical grid will definitely rise. To cope with this obstacle, an alternative source of
energy and an appropriate system of charging is necessary to develop. Photovoltaic in the
parking lots of working places is the most feasible solution to this problem. Because the cars
remain parked in the parking lots for most of the time.
This work proposed the possibility of developing a charging technique for EVs on priority basis
using solar energy. The main problem with solar panels is the variation in output power because
the solar insolation does not remain the same throughout the day. The dynamic charging
technique is proposed that will charge the EVs on priority using the available amount of output
power. This design presents a PV connected charging mechanism for EVs which uses two
control variables, SOC of battery and the duration of stay in charging station, easy to apply
lacking the need of exhaustive modeling. Suggested mechanism is entirely simulated in
MATLAB/Simulink and FIS is used for the design and selection of rules for FLC to analyze the
charging system characteristics and behavior. To ensure the practicability of designed technique
the simulation results are analyzed.
