Design and Analysis of a DC-DC fast EV charger for a Renewable energy-based EV Charging Station

With the recent developments in the Electric Vehicle (EV) sector, fast charging has emerged as a viable option to reduce charging times significantly. This paper addresses the critical challenges posed by the increasing number of EVs on the power grid, focusing on the necessity for reliable and efficient Level 3 charging solutions. To ensure rapid and sustainable charging, we propose a reliable and fast DC-DC charger that can be effectively integrated into solar-powered EV charging systems. This system charges LTO and NMC based battery up to $\mathbf{6 0 - 8 0} \mathrm{kWh}$ within $\mathbf{4 5 - 6 0}$ minutes. The proposed solution leverages advanced power electronics and optimization algorithms to enhance charging efficiency and grid stability. By incorporating solar energy, the system promotes renewable energy usage while mitigating the impact of EV charging on the grid. This paper also explores various strategies to manage the additional load, including the development of new charging infrastructure, energy storage systems, consumption limitations, and optimal power distribution.
