1. Wireless electromagnetic induction charging equipment can be invisible, with low equipment wear rate, wide application range and relatively reduced charging area.
2. It has high technical content and convenient operation, and can realize long-distance radio energy conversion.
Disadvantages of wireless charging:
1. Although the equipment has high technical content, its economic cost and maintenance cost are high.
2. Due to the realization of long-distance and high-power wireless magnetoelectric conversion, the equipment consumes high energy. With the increase of the distance and power of wireless charging equipment, the loss of useless work will be greater.
Extended data:
The principle of wireless charging:
1, electromagnetic induction type
Alternating current with a certain frequency in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thus transferring energy from the transmitting end to the receiving end.
2, magnetic field * * * vibration
It consists of an energy transmitter and an energy receiver. When two devices are tuned to the same frequency or vibrate at a specific frequency, they can exchange energy with each other, which is a technology being studied at present.
3. Types of radio waves
It is mainly composed of microwave transmitter and microwave receiver, which can capture the energy of radio waves bouncing back from the wall and maintain a stable DC voltage while adjusting with the load. This method only needs a transmitter installed on a wall plug and a "mosquito" receiver that can be installed on any low-voltage product.
