Wireless charging technology
- Jan 31, 2018 -

Wireless charging technology is derived from radio energy transmission technology, which can be divided into two ways: small power wireless charging and high-power wireless charging.

Small power wireless charging is often used by electromagnetic induction, such as the Qi mode of charging the mobile phone, but the induction type of the ZTE electric car is used in the wireless charging mode. High power wireless charging often adopts resonant mode (most electric vehicles charge this way), and the power is transmitted to the power supply device by the power supply device (charger), which uses the received energy to charge the battery, and at the same time, it is used for its own operation.

Because the power between the charger and the electric device is transmitted by magnetic field, there is no connection between the two wires, so the charger and the electric device can be exposed without conducting contacts.
