    This paper presents the general requirements for applying wireless charging systems to trams. Additionally, it proposes performance evaluation methods and testing items to ensure system reliability and interoperability. Since wireless charging systems transfer power through magnetic fields, general requirements such as rated power levels, operating frequency, temperature rise limits, and protection against induced voltage in nearby conductive materials are outlined. Testing items are categorized into component tests and integration tests. Component tests include dielectric voltage withstanding tests and environmental tests, while integration tests focus on evaluating system performance, such as wireless power transfer efficiency, load variation performance, and temperature rise under operational conditions. Wireless charging products developed based on the standards proposed in this study are expected to achieve high interoperability and broad applicability in the railway industry.
