2, the steps are as follows wireless charging receiving chip material : First the USB data cable connected to the phone with scissors or knife cut off the end, and then the long end of the data cable extendedCut a small section at the incision, you will see the green, red, white, black four wires, cut the green and black two, in the red and green two, respectively, cut a small section of insulation to reveal the copper wire.
3, the use of magnetic resonance technology principle, junior high school logistics textbooks have some knowledge, simply put: electric magnetic generation, magnetic generation wireless charge receiving film material ! The magnetic field generated by the coil is then converted into electricity by the receiving coil, which is why this wireless charging device often carries a thick base and a "phone case".
Magnetic absorption of the magnetic shell. The middle of the mobile phone case is embedded with a small ring holding wireless charging magnetic ring, which can improve the wireless charging effect of the mobile phone, and the magnetic force is as high as 10N, which perfectly matches the wireless charging ring of the charging device.
Wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer. There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate an electromagnetic signal, and the receiving end coil senses the electromagnetic signal of the sending end to generate a current to charge the battery.
The wireless charger uses the electromagnetic wave induction principle to charge, similar to the working principle of a transformer. There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate an electromagnetic signalThe signal generates an electric current to charge the battery. Electromagnetic induction charging This is currently the most widely used scheme, the circuit structure is relatively simple, the cost is low, but the transmission distance is short, affected by the location.
Electromagnetic induction is the most common working principle of wireless chargers. The transmitter generates a high frequency current through an AC power supply and an alternating magnetic field through an inductor. The inductor at the receiving end senses this magnetic field and converts it into electrical energy to charge the device. The advantage of this method is that the transmission efficiency is high and it is suitable for close charging. Electromagnetic radiation mode Electromagnetic radiation mode is a type of transmission through electromagnetic wavesThe way of energy.
