Research On Security Technology And Key Evaluation Index Of Wireless Charging System

The wireless charging technology frees the device from the "wireline" constraint,making the device more convenient to obtain power;according to the output power,it can be divided into low-power,medium-power,high-power wireless charging devices.This technology is expected to greatly promote the development of various industries and show a good application prospect.In the future,wireless charging products will be frequently used in daily life.Due to the incomplete knowledge of wireless charging technology and concerns about wireless charging security,this paper studies the technical security of wireless charging in order to better use wireless charging product;This article starts with the wireless charging technology standard and combines the security evaluation requirements,classifies the standards,selects the corresponding security evaluation indicators,according to the application scenario analyzes the modeling,builds the simulation platform for simulation verification,and proposes wireless New requirements for charging safety technology and measurement indicators on this basis.The first chapter of this thesis expounds the necessity and significance of researching wireless charging security,including the research and development of electromagnetic exposure at home and abroad.The second section outlines the technical,risk and safety requirements for wireless charging systems.The third chapter analyzes the key safety technical indicators and evaluation methods of wireless charging systems.The fourth chapter is based on the research in the third chapter,and build a key safety technical indicator evaluation model.The fifth chapter is the model construction and simulation verification of the key safety indicators with wireless charging system.The sixth chapter is a summary of the research on this paper.
