The integration of wireless energy transfer (WET) and advanced energy storage technologies is transforming how electric vehicles (EVs) and portable electronic devices are powered. This paper investigates Wireless Energy Storage Systems (WESS), focusing on the integration of WET technologies (inductive, capacitive, and microwave transfer) with modern energy storage solutions (batteries and supercapacitors). The paper examines how these systems combine to create contactless charging solutions for EVs and portable devices. Through case studies, it evaluates implementations and user feedback, providing real-world insights. Additionally, it identifies challenges (technical, economic, and regulatory) and opportunities, and predicts upcoming trends and potential impacts on industry and consumer behavior, offering a framework for understanding how this integration could revolutionize charging and energy consumption.
