Analysis of Influencing Factors of Wireless Charging Safety in Underground Coal Mine and Countermeasures

In view of the lack of relevant safety technical requirements and detection methods for wireless charging in underground coal mines, this paper proposes that electromagnetic induction wireless charging should be preferred to inductance coupling, electromagnetic radiation resonance energy coupling and magnetic coupling. The safety measures of wireless charging in safety distance, thermal energy, charging protection and safety control strategy are studied. At the same time, the explosion-proof of RF electromagnetic wave is analyzed and explored.
