Solar energy, harnessed from the sun, offers an abundant and clean power source, presenting an optimal solution for sustainable EV charging . However, solar intermittencies and photovoltaic (PV) losses are a significant challenge in embracing this technology for DC chargers.
This paper explores the performance dynamics of a solar-integrated charging system. It outlines a simulation study on harnessing solar energy as the primary Direct Current (DC) EV charging source. The approach incorporates an Energy Storage System (ESS) to address solar intermittencies and mitigate photovoltaic (PV) mismatch losses.
This will take great vigilance and strategic discipline as the parallel world of EV charging emerges and erodes their longstanding dominance. Because of the longer wait times EV charging requires, it’s also crucial that oil and gas retailers shift from a vehicle-centric to a customer-centric model.
Not only will demand grow over the next decade; so will the power output of the chargers themselves. Most chargers today are slow—below 22 kilowatts (kW)—but customers’ preference for speed and ease will make fast chargers (22kW to 149kW) and high-power chargers (more than 149kW) increasingly popular.
More energy is generated and stored at higher solar irradiance levels, so more power is available for EV battery charging. As a result, the SOC of the EV battery rises in proportion to the energy conveyed to it.
As a result of the study, it can be concluded that the incorporation of renewable energy sources in EVs, as well as the adoption of a dynamic wireless charging approach can significantly enhance the user experience by providing wireless charging options. This will result in less stress on the power grid.
