Application of wireless charging technology in consumer electronic products

The principle of wireless induction power transmission is to transmit electromagnetic fields through the transmitter coil and receiver coil at a close distance. The current radio energy transmission technology cannot independently and stably supply power to the device. The device also needs to rely on batteries to store electric energy, so it is usually called wireless charging technology The technology is favored by users in the field of portable devices for its incomparable portability. Wireless charging module DSCF0351.jpg Wireless induction charging in laptop phone headphones /AirPods Watches and other consumer electronic devices are widely used. At present, almost all portable devices need to consider adding wireless charging ports to provide convenience for users Wireless charging technology does not require wire transmission, breaking through the limitations of physical interface. In contrast to wired charging technology, wireless transmission technology can minimize the specific requirements of different devices for chargers. Wireless charging technology provides a friendly interface to reduce electronic waste by improving versatility At present, the disadvantage of wireless charging is that its structure is more complex than that of wired charging, which brings about the increase of cost. Wireless charging requires additional wireless charging coils at the charging end and device end, and it is less efficient than wired charger, which will generate more heat. These disadvantages limit its application in the pursuit of cost-effective middle and low-end equipment However, as this technology continues to develop and spread, I believe that these problems will soon have a good solution.
