What is the difference between wireless charging and wireless power supply?


Both are essentially derived from wireless transmission. Transmission, as we all know, is the technology of transmitting power from the power generation device to the receiving end without cable. At present, many people will mix wireless transmission, wireless charging and wireless power supply. Although the boundary between the three is not very clear, there are still subtle differences.


From the perspective of our consumers' use, we can simply understand:

Wireless transmission focuses on word transmission and power transmission, which is a process and a technology. Wireless power supply and wireless charging are two different ways to apply wireless transmission technology.

Wireless charging is more about charging the energy storage and charging equipment in the equipment. The key is that it is a charging. The object must bring the energy storage equipment or, generally speaking, the battery. At present, the more significance and application scenario of wireless charging is to charge the small battery equipment in a relatively fixed position.

Wireless power supply means that the wireless transmission equipment transfers the power to the consumers. The consumers do not necessarily need to store the power inside. It is more emphasized that the power can be transmitted and used immediately (of course, the battery can also be charged), and the power can be supplied to the consumers whose positions can be freely adjusted at a long distance. The significance of wireless power supply is more to provide power to household appliances with greater power consumption and meet the requirements of real and wireless power consumption. It can be said that wireless power supply is more difficult and meaningful than wireless charging.
