So, it is adopted for the present work. The objective of this work is to propose a Photo Voltaic (PV) based OFF-grid charging station for electric vehicles that uses PWM and a Phase Shift Controlled Interleaved Three Port Converter. Also, the proposed system is equipped with fuzzy based MPPT since the system is connected to PV system.
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 .
This paper concludes that the choice of charging strategy depends on the specific requirements and limitations of the off-grid solar PV system and that a careful analysis of the factors that affect performance is necessary to identify the most appropriate approach.
The battery storage system plays a critical role in the performance and reliability of off-grid solar PV systems, ensuring a consistent and reliable supply of electricity . Effective battery charging strategies are essential to ensure optimal battery performance and longevity in off-grid solar PV systems.
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.
Figure 11 depicts the PV system's output voltage and current. The DC output voltage and DC output current of the three port converter are shown to be 31 V and 17 A, respectively. In addition, the X-axis indicates a time in seconds in which the DC input is continuous and the source is pure DC. PV output voltage and current waveform

Because the voltage drop on the internal resistance is removed and the current is zero in the off-charging mode, the voltage of the vehicle battery and the station battery lowers. As depicted in Figure 35, a significant current is initially needed to charge the batteries, and thus the PV operates at MPP.
