advantage

The device that uses wireless magnetic induction charging can be invisible, the equipment wear rate is low, the application range is wide, and the area of public charging area is relatively reduced, but the share of the reduced area is not too large.

The technology content is high and the operation is convenient. Relatively long-distance wireless power conversion can be implemented, but the transmission distance of high-power wireless charging is limited to 5 meters and it will not be too far.

Easy to operate.

disadvantage

Although the technical content of equipment is high, the economic cost of equipment is relatively high and maintenance costs are large.

Due to the realization of long-distance high-power wireless magnetic conversion, the energy consumption of the equipment is higher. With the increase of the distance and power of the wireless charging device, the loss of effort will be greater.

The wireless charging technology device itself implements a secondary energy conversion, that is, the voltage reduction(or direct) of the network is converted into direct current, and a higher frequency switching control AC transformation output is performed. Because the high power alternating current conversion is the secondary wireless transmission of electric energy, the electromagnetic space magnetic loss rate is too large.
