Physicists have known for a long time that energy can be effectively transmitted between two objects with the same resonance frequency, while the interaction between objects with different frequencies is weak. This is the reason that a singer can shatter one of the bottles with different amount of water without affecting other bottles. It's just like when we swing, we just need to sit on it and let our drooping legs swing synchronously to bring power to the swing. Wireless charging technology is the use of this principle. Similarly, wireless charging technology also applies the principle of electromagnetic wave induction and related AC induction technology. At the sending and receiving end, the corresponding coil is used to send and receive the AC signal to generate induction for charging. Users only need to put the charging equipment on a "flat" to charge, This kind of charging method used to appear in watches and razors in the past, but it was unable to effectively charge large capacity lithium-ion batteries at that time.
