1, wireless charging refers to the device with a battery through wireless induction to obtain power and charge, its convenienceCan make consumers willing to pay an additional fee to buy wireless charging related products Wireless charging new code ; Because there are business opportunities, there will be manufacturers willing to invest in related product development, it can be known that many well-known brand manufacturers have included wireless charging this function in the new generation of product specifications.
2, distinguish between standard and non-standard PoE can measure the voltage through a multimeter, standard PoE will supply power after detection, and non-standard PoE is directly supplied. The stability of PoE power supply mainly depends on the quality of equipment and program design, rather than the technology itself, which is unstableThe power supply may be due to equipment quality problems or improper design. The larger the power, the better. Select switches based on actual requirements to ensure a balance between device power and the number of ports.
3, wireless power supply technology wireless power supply technology once it is commercialized, it will be particularly convenient, just like wireless charging code we use WIFI every day. With WiFi, we no longer have to worry about the loss of traffic, anytime and anywhere to use the wireless network to watch video. And this technology, led by the United States, they're using non-radioactive wireless energyTo charge, is a very applicable cutting-edge technology.
4, so the wireless power supply technology is still relatively far away from us. But wireless charging technology is really widespread. At present, automobile manufacturers such as Audi, BMW, Mercedes-Benz, Volvo, Toyota, etc., and communication companies such as Qualcomm have begun to study wireless charging technology for electric vehicles. 5, the concept of wireless power supply technology is not a new thing, as early as many years ago caused the attention and exploration of experts. Electromagnetic coupling is one of the common methods, and the transformer is the embodiment of its basic principle. Through twoThe separation of the windings enables wireless energy transfer, such as the charging of an electric toothbrush. However, due to the lack of a magnetic core with high permeability, the efficiency of energy transmission will decrease significantly when the distance increases, and it is not suitable for high-power and remote power supply.
