Dual Solar AC Charging System: A Review of Solar Photovoltaic Integration, Power Conversion and Electric Vehicle Charging Technology

The increasing demand for electric vehicles (EVs) and sustainable transportation has created a need for reliable, economical and environmentally friendly charging infrastructure. Solar photovoltaic (PV) energy provides a promising solution by utilizing renewable solar power for electric vehicle charging. This review paper presents an overview of a Dual Solar AC Charging System, in which two solar photovoltaic sources are integrated to provide electrical power for AC charging applications. The system can be designed with solar panels, solar charge controllers, maximum power point tracking (MPPT), power conditioning circuits, an inverter and suitable protection devices. The paper reviews existing solar-powered EV charging technologies, AC charging configurations, power electronic converters, energy management techniques and the challenges associated with solar energy utilization. It also discusses the possible integration of battery energy storage and grid backup to improve charging reliability during low solar irradiance and nighttime conditions. The dual-solar concept aims to improve solar energy utilization, reduce dependence on conventional grid electricity and support sustainable electric mobility
