1, the wireless charging of NFC is not to charge the mobile phone, which has little impact on mobile phone charging. In my opinion, the more likely impact of NFC support for wireless fast charging on mobile phones is that mobile phones integrate NFC modules, and there are more supporting devices that can achieve charging life through mobile phones in the future, greatly enriching mobile phone application scenarios.
2, some mobile phones now support wireless reverse charging, which is based on wireless chargingThe mobile phone does not support wireless charging, and it cannot carry out reverse wireless charging. With NFC wireless charging, even if the mobile phone does not support wireless charging, it can also use NFC to charge other devices.
3, but the use of NFC wireless charging, power and today's maximum 40W or even higher technology is not comparable. According to the NFC Forum, WLC (Wireless Charging via NFC Solution) can use an antenna in NFC-enabled devices to manage communication and charging, so currently only 1W charging speed can be achieved through this solution.
< p > 4, called WirelessChargingSpecification WLC is all in the last year has been included in the NFC wireless charging standard candidate, was formally adopted this year to become the official standard, its characteristic is the output power of 1 w, compared with the 15 w Qi state is still small, However, it is quite enough for some devices that use small batteries, such as smart wear, real wireless headphones, and stylus.5, power is king of domestic wireless charging Whether it is a stable Samsung, or pay attention to the experience of Apple, over the years, the power of mobile phone wireless charging is notThere are more than 15W, Apple is clinging to the 5W subsistence line, high power means difficult to control heat problems and higher patent pool costs.
6, it does not matter, NFC is high frequency, used to transmit signals; Wireless charging frequency is particularly low, the power is also large. Wireless charging and reverse wireless charging have become a common feature on high-end mobile phones, which use dedicated coils for radio energy transmission. Now the NFC Forum has announced the approval of a wireless charging specification that will allow users to wirelessly charge devices via NFC chips.
The reasons why Huawei mobile phone can not enable Mercedes-Benz wireless charging are as follows: Wireless charging requires the use of Qi charging technology, and Qi charging technology requires the use of NFC certification, and Huawei mobile phone NFC function is only to support NFC technology, but cannot support Qi charging technology, so Huawei mobile phone NFC function can not enable Mercedes-Benz wireless charging.
The reason why Mercedes wireless charging does not respond is: the battery is out of power; Starter failure; Driving computer failure; Battery pileThe head is loose. Mercedes wireless charging is turned on by default, you only need to put the phone in the wireless charging place, the phone can automatically charge. Mercedes belongs to the high-end car, wireless charging does not charge, it is best to 4s shop repair.
Mercedes wireless charging no response may have the following reasons: insufficient battery power, starter failure, driving computer failure and battery pile head loose. The wireless charging function of Mercedes is turned on by default, and you only need to place the phone in the charging area to charge it automatically. Taking the Mercedes-Benz E-Class as an example, the size of the car is 5078mm long, 1860mm wide, 1484mm high, and the wheelbase is 307>nfc connected wireless charging , there is no need to redesign the charging unit separately.
Such a low charging power to charge the mobile phone must be wait until the monkey horse, after all, NFC is not designed for charging, so this wireless charging scheme is more for low-power IoT devices, such as smart watches, fitness trackers, wireless headphones, digital pens and other consumer devices. It doesn't make much sense for high-consumption electronic devices like phones or pads.
WLC is intended to take advantage of the increasing popularity of NFC as a result of mobile paymentsThe carrier enables some small power devices to use simple wireless charging standards, allowing them to simplify electronic contacts and design simpler, more sealed iot devices.
I think that NFC support wireless fast charge on the mobile phone is more likely to affect the mobile phone integration NFC module, in the future, there are more supporting devices can achieve charging life through the mobile phone, greatly enrich the application scenario of the mobile phone.
/ And in today's Internet of everything, for low-power Internet of Things devices, NFC wireless charging solution is to solve the pain points of low power, such as smart watches, wireless headphones and other wearable devices charging needsWe get the optimization. The NFC wireless charging solution provided by ST is not only complete and compliant with the specifications of the NFC Forum, but also provides an ideal choice for the power supply of ultra-miniaturized devices.
Does not matter, NFC is high frequency, used to transmit signals; Wireless charging frequency is particularly low, the power is also large. Wireless charging and reverse wireless charging have become a common feature on high-end mobile phones, which use dedicated coils for radio energy transmission. Now the NFC Forum has announced the approval of a wireless charging specification that allows users to wirelessly charge devices via NFC chipsElectricity.
1, not through NFC Wireless charging technology; Wireless charge technology is derived from radio energy transmission technology nfc connection wireless charging , which can be divided into two ways of low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such asThe Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
2. Yes. According to Sohu, since 2020, smartphones can be charged wirelessly directly through nfc. nfc is near field communication, which supports short distance communication between compatible devices. You need at least one transmitting device and one receiving signal.
3, who told you that nfc is bullshit wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply equipment (charger) to transmit energyTo an electric device that uses the received energy to charge a battery and at the same time for its own operation.
4, the future use of mobile phone NFC module, you can directly carry out wireless backflush nfc connection wireless charging , but NFC is not designed for power supply after all, but borrow an antenna of NFC equipment for communication and charging at the same time, so the power is only 1W. Of course, the goal of the WLC specification is not to charge mobile phones, but for small products such as smart watches, smart bands, wireless headphones, stylus, and IoTEquipment.
