The working principle and performance index were analyzes for the high-power wireless power trans-mission （ WPT） system via magnetic coupling resonance （ MCR） . MCR-WPT system has longer transmission dis-tance and higher transmission efficiency compared with inductively coupled power transfer （ ICPT） to achieve high-power, long-distance, and high efficiency wireless charging of electric vehicle （ EV） . So, MCR-WPT has good ap-plication prospect and research value for EV field and can fully show the advantages of EV, such as wide distribu-tion, clean and green for environment and so on. Moreover, detailed experimental tests for the transmission per-formance of the self-built MCR-WPT system experimental setup are done and its correctness and effective is veri-fied.
