Abstract
At present, the analyzes of wireless charging system is mostly based on ideal state. When metal obstacle appears in the system, the system parameters will change. This paper takes the electric vehicle wireless charging system as the research objects, and analyzes the variation rules of the system resonance frequency and transmission efficiency when metal foreign matter appears at different positions within the fixed distance plane near the transmitter coil. When the metal objects on the transmitter coil, the transmission frequency of the system increased by 0.5kHz, and the transmission efficiency decreased by 5%.
