Wireless Charger is a charging device based on the principle of electromagnetic induction. Its principle is similar to that of transformer. By installing a coil at the sending end and receiving end respectively, the sending end coil sends electromagnetic signal to the outside world under the action of power, and the receiving end coil receives the electromagnetic signal and converts the electromagnetic signal into current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special way of power supply, it does not need power line, relies on electromagnetic wave propagation, and then converts electromagnetic wave energy into electric energy, and finally realizes wireless charging.

With the continuous improvement of power supply quality, safety, reliability, convenience, instantaneity, special occasions, special geographical environment and other requirements of electrical equipment, the contact power transmission mode can not meet the actual needs.
