Wireless charging technology

       Wireless charging technology comes from wireless power transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
       Electromagnetic induction is often used for low-power wireless charging, such as Qi mode for mobile phone charging, but ZTE's electric vehicle wireless charging mode adopts induction mode .
       High power wireless charging usually adopts resonant mode (most electric vehicles charge in this way). The power supply equipment (charger) transmits the energy to the power device, which uses the received energy to charge the battery and at the same time for its own operation.
       Because the energy is transmitted by magnetic field between the charger and the electric device, and there is no wire connection between them, the charger and the electric device can achieve no conductive contact exposure.
