There is a thermistor on the wireless charging coil to detect the temperature during charging. Type-C seat with steel plate inside, durable. Disassemble the family photo. Zte wireless charger products work neatly and look very comfortable. The input has electrostatic protection to avoid damage and reasonable design. Using components from well-known manufacturers in the industry,IDT scheme with diodes mos tube, the material used is mainstream level.
ZTE Tianji 10spro supports wireless charging. According to ZTE's official website: ZTE Tianji 10spro it supports Qi standard wireless charging only need to use wireless chargers that support Qi standard, wireless charging can be achieved. At the same time, the ZTE 10spro also supports 18W fast wired charging, and the fast charging function can make the battery fully charged faster and ensure a long time of battery life.
The principle of wireless charging is electromagnetic induction. Wireless charging mainly uses electromagnetic induction,The magnetic field transmits energy between the charger and the electrical device, and no wires are connected between the two, so the charger and the electrical device can be exposed without conducting contacts. With the continuous improvement of power supply quality and special geographical environment requirements of electrical equipment, the contact power transmission mode is increasingly unable to meet the actual needs.
ZTE's Blade 11 Prime offers Android 11 and wireless charging for under $200. The device proves that users can enjoy many of the features of high-end phones without spending a lot of money. Often, budget smartphones will be outfittedOperating system version, and updates are slow. However, the Blade 11 Prime starts with Android 11, giving users a modern starting point.
It also offers wireless charging, which we think should be a standard feature even on cheap phones, but often isn't. But it can also be reverse-charged via its USB-C port, so in a pinch, it's a portable battery for when you need it. It packs a 4,000mAh battery, which will make the prospect of reverse charging even more feasible.
Wireless charging can be divided into small workThe output tube is linked to the self-winding coil, and the connected two coils are close (about 1 cm or so there is sufficient charging current). The power supply can be wireless charged! The efficiency of this circuit is very low, because there is only half a wave peak high frequency so the loss is relatively large, but the principle is quite simple and easy to produce.
The so-called wireless charging technology only uses the electromagnetic wave induction principle and the related AC induction technology, and uses the corresponding coil to send and receive the induced AC signal at the sending and receiving end to charge. Nothing high-tech, just magnetic fields! The charger has a coilThe battery also has a coil on it, which, when placed close, forms something similar to a transformer. But it's very inefficient, and it's very radioactive.
Principle: The DC-DC switching power supply is divided into two parts at the high-frequency transformer, and resonant coupling is adopted; Then use RFID technology for data communication and current feedback. In a single-phase bridge rectifier circuit, if there is a filter capacitor, when the load is open, the output voltage (that is, the voltage at both ends of the capacitor) is the peak of the AC input voltage, that is, U output =414*U input, that is, the input voltage of the root 2 times.
What are the components of wireless chargingParts? The left side is TX, that is, the transmitter, and the corresponding product is the wireless charging transmitter. On the right is Rx, that is, the receiving end, and the corresponding product is a mobile phone with wireless charging function. TX end: MCU, power full bridge, and LC resonant Tank composed of inductors and capacitors, where the inductor is the transmitting end coil.
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 charge.
2, the wireless charger is actually the use of electromagnetic induction principle for charging equipment, similar to a transformer, there is a coil at both ends of the sending and receiving, the sending end of the coil connected to the wired power supply to generate electromagnetic signals, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to the electrical equipment. As shown in the figure below, current flowing through the coil creates a magnetic field. Its wireless charging product drawing His unenergized coil will generate current near the magnetic field.
3, electromagnetic induction: simple and efficient intimate contact electromagnetic induction, onLike a pair of tacit dancers, the sending end and the receiving end transfer power through inductive magnetic flux. It is known for its simple structure, high efficiency and low cost, and is especially suitable for close-range device charging. However, it also has limitations, limited transmission distance and strict location requirements, requiring accurate alignment to charge, as shown in Figure 4-1.
