2, high-power wireless charging is often resonant (most electric vehicle charging in this way) by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation;
3, because the charger and the electrical device between the magnetic field to transmit energy, the two do not use wire connection, so the charger and the electrical device can be no conductive contact exposed.
