Today to share with you why wireless charging is three-dimensional knowledge, which will also explain why to use wireless charger, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Wireless flash charging technology has gradually become popular and has become a common charging method in smart phones. The technology makes charging easier, allowing users to automatically charge their phones by simply placing them on a wireless charging pad. However, wireless flash charging works originalNot everyone understands how this works.
W Wireless flash charging vertical charger is plug and play, in the use of wireless charging, with the mobile phone standard charger connected to the device, and then the mobile phone left and right center vertical/horizontal screen on the base to achieve wireless charging, after charging the mobile phone removed, disconnect the power can be.

XFold, XNote, iQOO9Pro, X70Pro, iQOOThe device is composed of a charging head, a charging cable and a charging base. You need to purchase the charging base by yourself. To ensure charging quality and safety, you are advised to purchase the base from Huawei.
Unlike wired chargers, wireless chargers transmit energy through magnetic fields rather than wires or cables. The key to this working principle is the establishment of magnetic fields. In a wireless charger, a magnetic coil (commonly referred to as a coil) creates a magnetic field. When we place the phone in the inductive area of the charger, there is also a magnetic coil inside the phone, which can sense the magnetic field generated by the charger. The current generated by this induction can be used to charge a mobile phoneElectricity.
If the vivo mobile phone is used, 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.
Not all mobile phones can use wireless chargers. Some mobile phone model manufacturers in order to save costs or the main low-end models generally do not have wireless charging function. At present, the wireless charging of mobile phones on the market is almost Qi standard, because magnetic resonance and magnetic induction are not compatible, so the built-in Qi wireless charging receiver mobile phones, naturally can not use magnetic resonance technologyThe emitter is charged wirelessly.
ActuallyWireless charging technology still has a certain technical bottleneck, because in the process of electric energy → magnetic field → magnetic field → electric energy, there will be a large part of energy loss, so wireless charging still has a lot of room for progress.
S6 wireless charger, must be placed accurately, because the use of QI technology, the transmitter coil and the receiving coil are relatively small, not almost only 1/3 of the size of the mobile phone, so a slight mismatch, it can not be charged. It is also for this reason that Samsung's wireless charging mobile phones, or other similar QI wireless chargers, have not been promoted.
cityField application development bottleneck core wireless charging technology is not perfect; The radiation region is difficult to achieve long-distance transmission; Long distance positioning requires too much hardware. Magnetic resonance height matching can be controlled small; The application scope is limited and has not been extended; Market factors and consumer psychology make developers reluctant to vigorously develop technology.
This issue involves several key points of wireless charging. First of all, why do mobile phones choose wireless charging? In fact, this stems from the bottleneck of the long-term development of battery technology, the lithium battery technology used by mobile phones has been decades, and the contradiction between battery capacity and high energy consumption of smart phones is becoming more and more prominent. So as toTo solve this problem, mobile phone manufacturers have introduced fast charging and wireless charging technology.
It is also for this reason that Samsung's wireless charging mobile phones, or other similar QI wireless chargers, have not been promoted. Because of the technical bottleneck of QI, the current mainstream wireless charging technology is the technology of A4WP, which increases the charging area and charging distance by more than ten times, and does not need to be accurately placed when charging, and can be separated by 5-10cm.1, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
2, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. Currently on mobile phone,Electric vehicles, smart furniture and other fields have appeared to support wireless charging products. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
3, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
5, wireless charging principle: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
The advantage of using wireless charging is that it is convenient to carry, that is, put and charge, and there is no need to look for data cables and plugs everywhere. However, the charging speed of wireless charging can not be compared with the speed of current charging, and wireless charging is not really popular, so wireless charging can not directly replace current charging at this stage, but can be used as a replacement for current charging at the same time.
At present, no material can completely replace wires and switches, but there are some new materials can be used in certainTo some extent replace their function. The following are a few examples: Flexible circuit board: This material can be bent, folded, with good plasticity and durability, so it is widely used in mobile phones, tablets and other devices.
Efficient and convenient! But wireless charging is not a complete replacement for wired charging. Owners can still choose to use a wall plug for charging, which will depend on personal preference. Currently, the S500e plug-in hybrid model is only available in the California market.
This is not a problem for Apple fans, as long as the iPhone 13 is goodUse is enough. The iPhone 13 May also be equipped with a new A15 Bionic processor that supports Wi-Fi6E technology, which can bring a faster Wi-Fi experience.
Because wireless charging is less efficient than wired charging, it may take longer for two iphones to charge back to back than from a charger. In addition, if the power difference between the two iphones is large, the charging effect will also be affected. Back-to-back charging of two Apple mobile phones is an innovative technology that can bring convenience and security to users.Wireless charge why are standingThe introduction of the body talk here, thank you for taking the time to read the content of the site, more about why the wireless charger, wireless charging why are three-dimensional information don't forget to find on the site.
