Wireless charging base to increase the coil, or do not modify it, you increase the coil not only did not play a good effect but affect the speed of charging, increasing the coil is equal to increasing the resistance, it will make the current slow, the coil is proportionally wound, too much or too little can not, coil woundLess, there will be damage to the parts, resulting in burned parts causing sparks, because do not be free to modify the wireless charging base.
Wireless charging will not accelerate battery aging, will not have radiation to the body. The principle of wireless charging is electromagnetic induction. The charging dock is like an iron core with some primary coils wrapped around it. Cell phones have secondary coils built into them. The primary coil is energized to generate electromagnetic induction, so that the secondary coil generates induction voltage, and generates induction current to charge the mobile phone after loading. So don't worry.
No, increasing the voltage too much or increasing the number of turns will burn the battery, because you have more turns
Wireless charging technology mainly uses the principle of magnetic field transmission of energy to achieve power transmission without physical connection between the power supply and the device. Its basic principle can be summed up in two ways: electromagnetic induction and magnetic resonance. In the electromagnetic induction mode, the transmitting end and the receiving end of the wireless charging device have a coil. When the coil at the transmitting end is energized, a magnetic field is generated.
Electromagnetic induction: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring the energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.
Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. Electromagnetic induction: A certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wavesTransmission and other methods, mobile phone wireless charging mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
Magnetic resonance magnetometry is composed of a large inductor coil with a small capacitor in parallel or in series, and the same resonance 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 be the same at 10MHz frequency vibration, in order to receive this transmitted energy.
