1, wireless charging base increase coil, or do not modify itYou increase the coil not only does not play a good effect but affects 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, the coil is wound less, there will be damage to the parts, resulting in parts burned spark, because do not be free to modify the wireless charging base.
2, millet multi-coil wireless fast charging board is very careful in design, using silicone, aluminum alloy and PC material, built-in 19 efficient charging coils, can charge three devices at the same time, including mobile phones and wireless Bluetooth headphones. Official data shows that each device can enjoy up to 2Ready to charge at the same time, the maximum wireless charging power 15W X3, to provide users with mobile phones, headphones, smart watches and other integrated wireless charging solutions, no need to align, any position can be easily charged, recently more information about this charger revealed, the price of 799 yuan, open for sale in September.
Huawei new reveal: Beyond Apple's smart charging board, only 799 yuan starting at Huawei's new product launch in July, although Huawei P50 series and MatePad Pro 16 and other products stole the show, but a mysterious new product has not been ignored. This product is Huawei multi-device intelligent wireless chargingBoard, it has been officially listed, the price is only 799 yuan.
Whether it is Huawei, Xiaomi or Apple mobile phones, this charging board can be compatible, helping users reduce their dependence on mobile phones and improve the convenience of scientific and technological life. Overall, this 3-in-1 wireless charging pad with a sense of technology is recommended, adding utility and beauty to your desktop.Huawei Super Fast charge wireless charger (MAX 27W) : Align the coil center of the earphone case (the lower part of the earphone is near the back position of the LED light, not the geometric center) with the center of the wireless charger coil, and the indicator light is charged.
1, can not, excessive increase in voltage or increase the number of turns will burn the battery, because wireless charging coil stack The more turns you have the higher the voltage, wireless charging coil stack I don't know if your self-made charger is Qi program, if it is Qi, it is not possible, This one has to be closeDistance contact. You switch to radio, anything within five meters.
2, no harm to mobile phones. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
3, 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. Electromagnetic induction is generated by energizing the primary coil to make the secondaryThe coil generates an induced voltage, which generates an induced current to charge the phone after carrying a load. So don't worry.
4, although the technical content of the equipment is high, the economic cost of the equipment is higher, and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
5, the harm is relatively small can be ignored, wireless charging technology has appeared in the 19th century, but the popularity of mobile phone applications is not high. It uses the principle of "magnetic resonance" to allow wireless chargingThe device transmits an electrical charge through the air to the phone's battery. Many wireless chargers on the market do not indicate radiation values, and electromagnetic radiation standards for wireless chargers have not yet been introduced.
1. The primary secondary coil uses alternating flux coupling to generate induced electromotive force in the secondary coil. Lc circuit generally uses parallel resonant circuit.
2, wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive the induced current to enterLine charging.
3, magnetic field resonance technology: magnetic field resonance wireless charging requires two coils in the energy sending device and energy receiving device as resonators, composed of large inductors formed by small capacitors in parallel or in series, through the resonance effect for energy transmission, and the two devices need to be adjusted to the same frequency. Compared with electromagnetic induction, magnetic resonance wireless charging has longer transmission distance, higher power supply efficiency, and supports one-to-many power supply.
4, wireless charger coil active crystal output of the square wave, through the second-order low-pass filter to filter out high-order harmonics, get a stable sine waveOutput, through the triode 13003 and its peripheral circuit of Class C expansion circuit output to the coil and capacitor composed of parallel resonant circuit radiation in. Supply power to the receiving department.
5, wireless charger electromagnetic induction principle; Electromagnetic induction is used to charge by sending and receiving induced currents through the corresponding coils at the sending and receiving ends. It works by taking a magnetic field and putting it into a transformer that has a coil at the transmitter and a coil at the receiver. The capacitor is connected in parallel with the coil so that the resonant frequency of the two coils is the same.
6, electromagnetic induction. chargingWhen the two are close, the transmitting coil generates a certain current in the receiving coil of the mobile phone based on the alternating current of a certain frequency through electromagnetic induction, thus transferring the electrical energy from the transmitting end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
1, through the power module after the output of the DC through 2M active crystal inverter into high frequencyCommunication electrical supply lower winding. By coupling the energy of the two inductors, the electrical output of the secondary coil is changed into direct current through the receiving conversion circuit to charge the battery.
2, wireless charging base to increase the coil, or do not modify it, wireless charging coil superposition You increase the coil not only did not play a good effect but affect the speed of charging, increase wireless charging coil superposition the coil is equal to increase the resistance, The current will be slow, the coil is proportionally wound, too much or too little can not, the coil is less, it will be lossyBad parts, resulting in parts burning cause sparks, because some do not arbitrarily modify the wireless charging base.
3, millet 20W vertical wireless charger Jingdong opened for sale, only 99 yuan! Xiaomi's newly launched 20W vertical wireless charger, which hit the shelves on JD.com today, has caught the attention of consumers with its unique double coil design.
