Conclusions In this study, we investigate the use of an off-grid solar photovoltaic system for the charging of electric vehicles at long-term parking lots. The effectiveness of the off-grid system is studied through analysis of the states of charges at departure of the EVs plugged in at the parking lot over the simulated year.
In off-grid photovoltaic (PV) systems, a battery charge controller is required for energy storage. However, due to unstable weather conditions as well as the frequent variations in load demand, the PV power flow delivered to the load could be fluctuated while the battery charging efficiency will be reduced.
This is particularly important in remote areas where grid electricity is not available, and reliance on diesel generators can be expensive and environmentally damaging . There are several battery charging strategies used in off-grid solar PV systems, and each strategy has a different impact on the system’s performance.
Charge controller - high-quality PV charge controller is the most important component within the PV off-grid systems. Controls the flow of current to and from the battery, to protect it from over charging after reaching the required voltage within the battery (eg protect against boiling the electrolyte).
Here are some steps to follow when designing batteries in off-grid solar PV systems: Determine the energy needs: Calculate the amount of energy needed to power the load (s) in the system, considering factors such as the time of day, weather conditions, and seasonal variations .
