摘要：Metal detection technology is required for the diffusion of electric vehicle wireless charging technology because the wireless charging system mixed with the metal will bring a very serious security risks. This problem is getting more and more attention. This paper introduces the principle of the balanced coil technology first, and then the design of an improved balanced coil probe is presented. Finally, the metal detection system based on MCU is designed. Experiments show that the detection technology has high sensitivity and excellent anti-interference.
