1, in response to the huge demand brought by the continuous hot TWS headset market, Fuhengtai released a 5W receiving power TWS wireless charging box dedicated PCBA module, the board does not change to support wireless charging, the maximum processReduce customer development costs.
2, the problem is mainly in the wireless reverse charging function. Logically, turn on the function, the phone turns over, uses the backplane as a "wireless charging board", puts the TWS headphones, smart watches and other devices that support wireless charging on it (roughly aligned with the center of the coil), you can enjoy the "reverse blood" from the flagship machine.
3, BeoplayE8 0 true wireless Bluetooth headset appearance and the previous generation has changed little, but on charging, the use of wireless charging technology - just put the charging box on the wireless charging board, you can be BeoplGenerally only ten centimeters is more effective. Because the transmission distance is very close, in order to achieve charging, the device to be charged must be close to the charger in order to charge. After that, it doesn't work. 3, now Bosch a set of wireless charging equipment is about less than 20,000 yuan, and the traditional charging pile plus car charger domestic average price of about six or seven thousand yuan, it should be said that there is a certain gap, the future wireless charging technology should focus on improving the reliability of the system and the adaptability of the environment.
4, wireless charging technology is transmitted by magnetic field between the charger and the electrical deviceTo send energy, no wires are connected between the two, so the charger and the device that uses electricity can be exposed without conducting contacts. The principle of fast charging of mobile phones is to increase the input value of the charging voltage or current. However, in order to truly realize fast charging of mobile phones, it also needs supporting circuits and hardware. The fast punch technology mainly includes Qualcomm's Quick Charge and Mediatek's Pump Express.
5, wireless charging charging speed is very slow, which is hard. Now is the world of high-power fast charge, although each fast charge solution is not the same, but the power is fundamentally maintained at about 18w, high even to 24w, used to being filled within an hour and a half, but now it has to go back to the past, 5w 8w Max 10w charging speed, it is not acceptable, and it can not move, the position is biased, and the speed is lower.
6, wireless fast charge is not very fast, nor very slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Actually inputThe wireless fast charging efficiency of 18W is 60% after 2 and a half hours of charging.
