Wireless charging. How far can we go?

1, generally about 0.9-2 meters high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.

2, currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. Existing wireless charging technologies use magnetic fields, electromagnetic waves, lasers,Unified power supply. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.

2, the principle is to convert the environmental electromagnetic wave into current through the circuit to transmit current. This way the transmission distance is greater than 10 meters, which is suitable for long-distance low-power charging, and can also realize automatic charging anytime and anywhere. WiFi wireless charging. It mainly consists of two components, one is a Wi-Fi access point (router), and the other is a customized charging sensor.

3, wireless charging system mainly uses the principle of electromagnetic induction. wirelessThe charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magical transmission of electric energy, inductive coupling technology will become the bridge connecting the charging base station and the device.

What is wireless charging? What are the misunderstandings of wireless charging?

1, the first is the distance limitation, because the conduction distance of electromagnetic induction is limited, generally speaking, wireless charging equipment needs to be with a chargerKeep it a few centimeters to tens of centimeters away to charge. The second is the difference in performance, because different phones and chargers have different power, so there may be slower charging speed.

2, advantage one: reduce the loss. As we all know, when using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large amount of loss and waste of data lines, which is relatively an environmentally friendly charging method. Benefit 2: high adaptation rate.
