1. The steps are as follows: First use scissors or knife to cut the wireless charging coil magnet at the end of the USB data cable connected to the mobile phone, and then cut a small section of wireless charging coil magnet at the incision of the long end of the data cable, you will see green, red, white and black four lines. Will the green and black one twoCut off the strips and cut off a small section of insulation between the red and green ones to expose the copper wire.
2, open the back cover of the smartphone, and then take out the wireless charging receiver ready; Or the protective layer of double-sided tape peel; The next task is to connect the receiver's metal shock to the smartphone battery, which is the most difficult part of the process. However, as long as you are careful to ensure that each metal shock is connected together, it can be done.
3, question 1: How to make wireless charger wireless charging coil magnet ? wirelessIron. Some wireless chargers have a magnetic design, such as Apple's MagSafe, which uses magnets to attract the device for positioning and charging.
2. Yes. The changing magnetic field can produce an electric field, and the strong magnet is a static magnetic field, so it will not affect the wireless charging process.
3, according to the theory, this should be affected, because the principle of wireless charging is to generate a magnetic field through the power supply, and then the induction coil in the mobile phone to convert the magnetic into electricity, if there is a magnet sheet, it may complete the magnet sheet heat, may cause problems.
4, wireless charging is the transmission of magnetic field energy, magnetic materials will affect the magnetic field, will block the magnetic field transmission, no magnetic field, there is no energy, so it will affect wireless charging.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone directly (vertically) or horizontally in the center position of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick.

The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output DC is inverted by 2M active crystal oscillatorSwitch to high frequency AC to supply the primary winding.
Wireless charging technology is derived from radio energy transmission technology, 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, high-power wireless charging often uses resonance. The power supply device transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
Now the wireless charging is more common magnetic resonance charging mode. It's based on the principles of magnetic resonance technology, which you can read in a junior logistics textbook, JaneSimply put: electricity generates magnetism, magnetism generates electricity! 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".
