1. Driven by technological innovation, Nanxin Technology constantly breaks through the boundaries of wireless charging technology. The birth of SC9610&SC8701 marks the arrival of a new era of high-power wireless charging. These two products not only represent the outstanding technical strength of Nanxin Technology, but also promote the development of the entire industry to higher power and higher efficiency.
2, accompanied by Liu Min and Liang Yingzhen, Director Wang Yong and his delegation first visited the Shanghai office of Nanxin Technology. They browsedSome representative schemes and terminal product cases of Nancore Technology, and in-depth understanding of several representative fast charge schemes and in-depth cooperation terminal projects, including charge pump scheme SC8571 series, high-power wireless charging scheme SC9610 series, 65W gallium nitride scheme and pre-loaded car charging scheme.
1, mobile phone space charging technology is to install the transmitter coil on the wireless charging base, install the receiver coil on the back of the mobile phone,When the mobile phone is charged near the charging base, the transmitting coil will generate an alternating magnetic field due to the access to alternating current. The change in the magnetic field generates an induced current in the receiving coil, which transfers energy from the transmitting end to the receiving end, and finally completes the charging process. (2) The principle of electromagnetic resonance wireless charging technology is the same as the resonance principle of sound: an energy sending device and an energy receiving device are adjusted to the same frequency, and each other's energy can be exchanged when resonating, so that the coil in one device can transfer electrical energy to the coil in another device at a distance to complete the charging.
3. NoneWire space charging technology is a wireless charging technology that enables electronic devices to achieve wireless charging through electromagnetic induction, magnetic resonance and other principles without plugging wires. The principle is that the electromagnetic wave signal is emitted through the transmitter (charger), and then the electromagnetic wave is received by the receiving end (electronic device), and the received energy is converted to achieve charging.
4, in short, the wireless charger is actually a charging mode that relies on the energy of electromagnetic waves to convert electromagnetic waves into electrical energy.
5, space charging technology is actually a wireless charging technology. Wireless charging technology is a non-usePhysical contact to achieve the transfer of electrical energy technology. At present, there are three common wireless power transmission technologies, respectively: electromagnetic induction: the working principle is: install the transmitter coil on the wireless charging base, install the receiving coil on the back of the mobile phone, when the mobile phone is near the charging seat to charge, the transmitter coil will generate alternating magnetic field due to access to alternating current.
1, the Ministry of Industry and Information Technology regulations wireless fast charging superRange wireless charging power must be less than 50 watts, there is such a over-the-range wireless charging requirements in the end why they are not clear, but they know the limit, the power of this charge is not because of radiation, because radiation is everywhere, all the time. Not all radiation affects the human body.
2, to be precise, split sales, standard changes separate retail, this is illegal, because this makes the commodity can not achieve its normal use, only with accessories to normal use, in order to be the commodity itselfFunctional, so these accessories are necessary, must.
3, several requirements of the subject, over-the-range wireless charging We can sum up, large battery, do not have hot phenomenon during use, the appearance level is higher. Then we carefully subdivide the demand, the large battery means that the subject needs better battery life, that is, the battery capacity is large and suitable for strong fast charging. The use of the process do not have a hot phenomenon is actually its own processor performance and manufacturer optimization. At a higher level of appearance we try to satisfy what most people find attractive.
What are the electric distances? 1, generally about 0.9-2 meters high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.2, the distance is greater than 10 cm, the conversion efficiency is only about 60%, that is, the sent power is 1000W, the received only 600W.
3, if according to the charging efficiency phaseIn terms of normal and harmless standards to the human body, the farthest distance that can be done now should be 5-10cm, and domestic micro goose technology and Qualcomm should be able to do it. And this is not the public familiar with Qi wireless charging, is magnetic resonance wireless charging, based on the principle of magnetic resonance. Although there are also 1 meter or even farther wireless charging technology, but the current charging power of these are too small, charging speed is too slow, difficult to put into daily use.
4, that needs to be placed next to the transmitter), at the same time, they are also studying long-distance wireless charging, which will be an emerging market. In fact, the current technology can reach 3 feetEffective power transmission within a range of ~ 4 feet, but this needs to be verified by the relevant organization. I believe that in the next 5 to 10 years, or even sooner, long-distance wireless charging will enter everyone's life.
5, the core magnetic resonance long distance wireless charging developed by Spuroting can successfully achieve wireless charging within one meter.
6, System: iOS 16, iphone14pro wireless charging power is maximum 15W, using MagSafe wireless charging technology, can achieve fast wireless charging and alignment between the product and the charger morePlus convenience and precision. At the same time, the technology has a built-in security chip to ensure charging security and data privacy.
Several factors that affect the wireless charging speed: power plug power over-the-range wireless charging , power cord over-the-range wireless charging , wireless charger power, mobile phone wireless charging receiving power, mobile phone case, mobile phone stand. nowIn the wireless charger technology has been very mature over-the-range wireless charging , product quality stability is also very high, so when there is a problem, over-the-range wireless charging we should first check to eliminate the above problems, will save more time and trouble.
To use the Mi 11's wireless charging feature, first make sure you have a compatible wireless charger. Place the Mi 11 phone on the wireless charger, making sure there is good alignment and contact between the phone and the charger. Once the phone is properly connected to the charger,The Mi 11 will automatically start charging. Instructions for Wireless charging When the Mi 11 is wireless charging, you will see a charging instruction on the phone.
Step 1: Confirm that the device supports wireless charging First, we need to confirm whether our millet 11 supports wireless charging function. You can view this information in your phone's Settings. Enter "Settings" - "Battery and Performance" - "Wireless charging", if the "wireless charging" option appears, it indicates that the device supports wireless charging. Step 2: Prepare a wireless charger After confirming that the device supports wireless charging, we need to prepare a wireless chargerAppliances.
This is caused by the use of high-energy applications, too many applications running in the background of the phone, too many mobile phone functions, or hardware problems of the phone. Temporarily use applications with high energy consumption. Close the application running in the background of the phone. Turn off functions you don't need on your phone. Mi 11 charging speed: from 1% to 55% in 15 minutes.
First, confirm device compatibility Before enabling wireless charging, it is key to confirm whether the Mi 11 has this function. The standard configuration of the Mi 11 includes support for Qi wireless charging, so as long as you are a Mi 11 user, there is no need to worry. For its over-the-range wireless charging other models, it is recommended to consult Xiaomi's official website or other official information to determine whether the phone supports wireless charging.
Mi 11 wireless charging only needs to connect the wireless charger to the power supply, and then put the phone on the charging base, and wireless reverse charging needs to be opened in the phone. Here's how to do it: In the phone's Settings menu, tap on "Save Power and Battery". Open [Wireless reverse charging] in the "Battery" page, and then put the phone back to back with the device that needs to be charged.
1, wireless charging technology is relatively new technology at present. The principle is somewhat similar to the propagation of electromagnetic waves in the air, but the transmission distance is not far, generally only ten centimeters to be 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.
2, wireless charging principle: electromagnetic induction. The charging dock and the phone terminal have built-in coils,When the two are close, the alternating current of a certain frequency based on the generator coil generates a certain current in the receiving coil of the mobile phone through electromagnetic induction, so as to transfer the point energy from the source to the receiving end, and then start to supply power from the charging seat to the mobile phone. Magnetic resonance.
3, if the use is vivo mobile phone, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
4, generally about 0.9-2 meters high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into small workRate wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
5, a lot of energy waste magnetic resonance wireless charging technology needs to establish a magnetic field between the transmitter and the receiver for energy transmission, but the formation and maintenance of the magnetic field requires the consumption of a lot of electrical energy, and in the transmission process will also produce a certain amount of electromagnetic radiation.
6, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, mobile phoneWireless 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.
