Advantage

The equipment using wireless magnetoelectric induction charging can be invisible, with low wear rate, wide application range, and relatively reduced public charging area, but the share of reduced floor area will not be too large.

With high technology content and convenient operation, it can implement relatively long-distance radio energy conversion, but the transmission distance of high-power wireless charging is limited within 5 meters, not too far.

Easy to operate.

shortcoming

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

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

The wireless charging technology equipment itself realizes the secondary energy conversion, that is to say, after the network voltage is reduced (or directly) to DC, a higher frequency switch control AC conversion output is carried out. Because the high-power AC-DC-AC current conversion is the reason for the secondary wireless transmission of electric energy, the electromagnetic spatial magnetic loss rate is too large.
