Foreign Objects and Living Organism Detection System for the Wireless Power Transfer Active Zone in E-Mobility

Abstract

Presented paper describes foreign object detection system for wireless power transmission in electro mobility applications. System monitors energy transmission active zone to avoid material damage, deterioration and life organism injury caused by strong and high frequency electromagnetic field. Specific application in electro mobility area places great demands not only on detection reliability but also on the sensors and detection system design and lifespan. Specific working environment is characteristic by, pollution, dust, humidity, salt solutions act. So, magneto-electric induction, ultrasound and electric values monitoring are used in proposed system to ensure resistance to environmental influences. Detection algorithm description is also part of this article. Proposed system accordance to SAE TIR J2954 is sure thing as well as system testing on laboratory prototype.
