Magnetic resonance: A new breakthrough in long-distance transmission Magnetic resonance technology takes a different path, which realizes remote transmission through resonator and magnetic field resonance. Especially in the field of electric vehicle charging, efficiency improvement is the focus of research. As shown in Figure 4-2, through the resonance principle, the energy is efficiently coupled between the transmitter and the receiver in the form of a magnetic field, which realizes the wireless transfer of energy, even inPool charging.
MRI. A magneto consists of a large inductor coil with a small capacitor in parallel or in series, and the same resonant frequency is a necessary condition for energy transfer. For example, two coils are used as resonators, the transmitting end vibrates at 10MHz to radiate an electromagnetic field around, and the receiving end needs to vibrate at 10MHz to receive this transmitted energy. Radio waves. The principle is to convert environmental electromagnetic waves into current and transmit current through a circuit.
The core principle of wireless charging is actually electromagnetic induction, and the principle is not complicated. So far, the industry has been dominated by twoAirplane.
Mobile phones that support wireless charging are: Nut R1 Nut R1 is a flagship mobile phone released by Hammer technology in May 2018, and it is also the first hammer mobile phone that supports wireless charging. In terms of appearance, the Nut R1 uses a three-narrow border shaped full-screen design, the beauty pointed front camera fringe design, and the jaw is relatively narrow, and the screen proportion is high.
