1, wireless charging coil above the thermistor wireless charging coil factory , detectionTemperature Wireless charging coil factory when charging. Type-C seat with steel plate inside, durable. Disassemble the family photo. Zte wireless charger Wireless charging coil factory products work neatly, look very comfortable. The input has electrostatic protection to avoid damage and reasonable design. Using well-known manufacturers in the industry components, IDT solution with diodes mos tube, the material is the mainstream level.
2, ZTE Tianji 10spro supports wireless charging. According to ZTE's official websiteThe coil conducts electromagnetic induction, but directly through the high frequency electric field in the capacitor formed between the charging base and the electrical device to be charged, that is, the induction electric field generated by coupling two sets of asymmetric dipoles in the vertical direction is used to transmit power. This charging method has the advantages of low cost and low alignment requirements. But there are not many actual products.
2, electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger transmission coil) will generate a magnetic field, other unenergized coil (mobile phone end of the coil) close to the magnetic field will generate current, charging for the mobile phone. Advantages of wireless charging Security: no power contact setThe risk of electric shock can be avoided.
3, because the charger and the electrical device transmit energy by magnetic field, the two do not use wires to connect, so the charger and the electrical device can be no conductive contact exposed. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
4, the main features from the theory, wireless charging technology, safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, only in the same frequency resonance coilBetween transmission, and other devices cannot accept the band, in addition, wireless charging technology uses the magnetic field itself is harmless to the human body.
5, skin "pathway. By comparison, it can also be seen that the heat output of a high-frequency transformer with the same power and volume is much larger than that of a multi-strand enamelled hoff winding. Wireless charging frequency 100KHZ-200KHZ The receiving end often has a single strand, 2 strands, 4 strands, there are also 8 strands, 13 strands of hot air lines, considering the thickness, the receiving end is side-by-side, unlike the transmitting end twisted together, 13 strands side-by-side winding is very difficult.
The material cost of the core electronic part is about ten yuan. The wireless charging system first selects the electromagnetic induction principle, and ends the energy transmission through the intermittent energy coupling of the coil. When the system is working, the input end converts the AC mains power into DC power through the full-bridge rectifier circuit, or directly supplies the system with 24VDC power. After the output direct current passes through the power processing module, it is converted into high frequency alternating current through the 2M active crystal oscillator inverter to supply the primary side winding.
Wireless charging mode is composed of this wireless charging adapterBen. According to the query of the digital home website, wireless charging module composition: wireless charging module accounts for about 15% of the total price of smart phones, and the cost of each link is expected to decline rapidly. Wireless charging adapter cost: Wireless charging adapter is an important part of wireless charging, the cost also affects the cost of the entire wireless charging system.
meta. Homemade air-cooled wireless charging, fan cost 10 pieces, wireless charger cost 15, total cost 25. Xiaomi official website directly sells all products under the Xiaomi company.
High cost of wireless charging equipment: Wireless charging equipment needs to use high powerWireless charging coils and batteries, but also need to cooperate with related technology and equipment, the cost is high. Large power consumption of wireless charging equipment: The greater the power of wireless charging equipment, the more electricity it needs to consume, which will cause greater pressure on the environment and energy.
Disadvantages of wireless charging efficiency is slightly lower: the general charger also has a transformer, but the wireless charging transformer composed of the transmitting coil and the receiving coil is limited in structure, and the energy transmission efficiency is theoretically slightly lower than that of the general charger. Slow charging speed: Due to the current mobile phone and other receiving devices, most limit the input power, so the charging speed is slow.
On the back of the machine, right in the middle. The irregular round part in the middle of the picture is the part that charges (or discharges) wirelessly.
After the wireless charger is powered, directly place the phone screen facing up in the center of the charger or the position suggested by the manufacturer to charge.
How to set Huawei p40pro wireless charging? Connect the charging head to the charging base using a data cable, and then plug the charging head into the power supply. Will be chargedPlace the base on the table and place the phone screen facing up in the center of the charging base. After the phone is placed on the charging base for a few seconds, there is a "drip" sound, indicating the start of charging. I tip: The wireless charger is composed of a charging head, a data cable and a charging base.
Huawei P40Pro supports wireless charging, the mobile phone has a built-in 4200mAh large-capacity battery, the use of mobile phones to play games, watch movies, listen to music has a long battery life, and the mobile phone supports 40W wired flash charge 27W wireless fast charge reverse charging.
Mobile phones that support wireless charging are: Huawei Mate40E Pro, Huawei P50 Pro, Huawei Mate 40E, Huawei Mate 40 Pro, Huawei Mate 30 Pro, Huawei Mate 20 Pro, Huawei P40 Pro, etc.
As a high-end smartphone owned by Huawei, Huawei p40pro is equipped with advanced wireless charging function. The use of this feature is very convenient, users simply place the Huawei p40pro on a compatible wireless charger to start charging, without the need to plug in a traditional charging cable. Wireless charging not only improves chargingThe convenience also reduces the interface wear problem caused by frequent plugging and unplugging of the charging cable.
