Wireless charging technology

Wireless charging technology(English: Wireless charging technology; Wireless technology is derived from wireless power transmission technology and can be divided into low-power wireless charging and high-power wireless charging.

Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. High-power wireless charging often uses a resonant type(most electric car charging in this way) to transfer energy from a power supply device(charger) to a device that uses the received energy to charge the battery and at the same time for its own operation.

Since the charger and the electric device transmit energy with a magnetic field, there is no wire connection between the two, so the charger and the electric device can be exposed without conductive contacts.
