The wireless charger is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By placing a coil at the transmitting and receiving ends, the transmitting end coil sends an electromagnetic signal to the outside under the action of power, and the receiving end coil receives the electromagnetic signal. Signal and convert electromagnetic signal into electric current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special power supply method that does not require a power cord and relies on electromagnetic wave propagation, and then converts the electromagnetic wave energy into electrical energy, and finally realizes wireless charging. However, the export of wireless chargers to Europe requires CE certification before they can be sold.

Importance of CE-EMC testing

EMC is a very important quality index. It is not only related to the working reliability and safety of the product itself, but also may affect the normal operation of other equipment and systems, and is related to the protection of the electromagnetic environment. The European Community government stipulates that since January 1, 1996, all electrical and electronic products must pass EMC certification and be affixed with the CE mark before they can be sold on the European Community market.
