7. EXISTING SYSTEM Current Electric Vehicle (EV) charging infrastructure predominantly relies on plug-in charging systems, requiring physical connection between the EV and charging station via cables. While effective, this approach presents limitations such as inconvenience, susceptibility to wear and tear, and potential safety hazards. Additionally, plug-in charging systems may not always be compatible with different EV models, hindering interoperability. Despite advancements in fast-charging technologies, the need for manual intervention remains a bottleneck. Addressing these challenges, static wireless charging systems have emerged as an alternative, offering seamless and contactless charging experiences for EVs, thereby mitigating the limitations associated with traditional plug-in charging methods.
