1, electric field coupling wireless charging, does not use the coil for electromagnetic induction, but directly through the charging base and the electrical device to be charged between the capacitor in the high-frequency electric field, that is, by coupling two groups of asymmetric along the vertical directionThe induction electric field generated by the dipole transmits power, which has the advantages of low cost and low alignment requirements. But there are not many actual products.
2, the number of wireless charging coils is based on the number and size of the charging device to be charged. In theory, the more coils there are, the more efficiently the device can be charged, because the device can receive the charge at any location. However, if the number of coils is too large, it will increase the cost and volume, which is not practical or economical. Therefore, the appropriate number of coils should be selected according to different charging needs.
3. No. Every wireless charging coil will have itWith a certain amount of energy loss, increasing the number of coils will lead to a decrease in the overall charging efficiency, and more coils will increase the energy loss and mutual interference, thus reducing the efficiency of wireless charging. And increasing the number of coils requires more coils and associated circuits to be installed in the device, which increases design complexity and cost.
4, the car charger uses the car cigarette lighter as a power socket to charge the mobile phone directly. Since the voltage provided by the car is low, only overload protection circuits are needed inside the car charger. The front end of the car charger socket is designed with a safety tube to withstand when the current exceeds the overload protection circuit/h2>
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, increase the coil is equal to increase the resistance, it will make the current slow, the coil is proportionally wound, too much or too little can not, coil wound less, there will be damage to the parts, resulting in parts burned spark, For some do not arbitrarily 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. Mobile phone internal selfWith secondary coil. 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.
Can not, too much increase the voltage or increase the number of turns will burn the battery, because the more you turn the higher the voltage, I do not know whether your self-made charger is Qi program, if it is Qi, it is not possible, this must be close contact, you have to change to radio wave type, within five meters.
does no harm to mobile phones. The wireless charger uses the latest wireless charging technology by enablingUsing alternating magnetic fields generated between coils to transmit electrical energy, inductive coupling technology will become a bridge connecting charging base stations and devices.
I recommend Shenzhen Jinhade Inductance Company, their company specializes in mobile phone wireless charging coils, receiving coils, transmitting coils are done, and is free to do samples, customized various models, inductive value of wireless charging coils, also has ISO quality certification, in line with QI standard. All mechanical automatic production, fast delivery. I hope this helps. Please hit "Like". thank you.
