1, w wireless fast charge refers to the wireless fast charge technology power reached 50W. The 50W wireless charger can almost complete the entire charging process of the 4500mAh large-capacity battery in less than 50 minutes. That's about the same speed as most wired fast charges today.
2, Huawei Mate 60 Pro as Huawei's high-end flagship mobile phone, its charging technology is the sameTake the lead. The 50W wireless fast charge power means that users can quickly charge their mobile phones in a short period of time, which is very convenient for modern people, especially in busy lives, time is particularly precious. In addition, wireless fast charging technology also provides users with a more convenient way to charge, no longer need to worry about cable winding and plugging problems.
3, W and 50W refer to the power output of the wireless fast charge, representing the charging speed and efficiency provided by the wireless charger. Here is the difference between them: Charging speed: 50W wireless fast charge has higher power output compared to 40W wireless fast charge,Therefore, it can provide faster charging speed. This means that when charging with 50W wireless fast charge, the charging time of the device will be shorter. Compatibility: 50W wireless fast charges are generally compatible with a wider range of devices.
4, W wireless charger refers to the charger to charge the maximum charging capacity of the mobile phone, if the maximum power of the charging head is less than 50W, the maximum output power is the same as the charging head, if the power of the charging head is greater than 50W, the maximum power of the charger is 50W.
Charger OEM: The main enterprises include Aohai Technology, BYD Electronics, Tianbao, Selkang and so on. In 2020, fast charging technology enters the era of hundreds of watts. In August 2020, OPPO and Millet new machines are equipped with 120W fast charging, and fast charging technology has officially entered the 100-watt era. According to Xiaomi Lab data, the 100W fast charge takes only 17 minutes to fill the 4000 mAh battery. The increase of fast charge power drives the rapid increase of mobile phone charger prices.
Aohai Technology: wireless charging leader, is a focus onIntelligent terminal charging and storage products R & D, production and sales of national high-tech enterprises. Hengdian Dongmagnetics: one of the largest manufacturers of magnetic materials in China, wireless charging magnetic materials have been adopted by a number of industry-leading customers. Haineng Industry: wireless charging leader, wireless charger is the company's mature products.
Antenna design and manufacturing technology is expected to expand to wireless charging, NFC and other fields: although the company has not launched wireless charging coils, but because of the company's experience in metal precision structure has been precipitated, the company's management has proposed to expand the company's antenna design and manufacturing technology to wireless chargingPlanning in the field of electricity, NFC, smart home and other products.

Jingquanhua (002885) (002885) annual report: Net profit of 55 million yuan, net profit growth rate of 1180.62%, operating income of 11.1 billion yuan. Hengdian Dongmagnetic (002056) annual report: Net profit of 9.7 billion yuan, net profit growth rate of 496%, operating income of 96.9 billion yuan. Lianchuang Electronics (002036) Annual Report:Line charging can be seen everywhere, so what is the principle of wireless charging? '> Now that wireless charging is everywhere, what is the principle of wireless charging? 1, electromagnetic induction type: The fundamental principle is the use of electromagnetic induction principle, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.
2, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wavesTransmission and other methods, mobile phone wireless 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.
3, wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. Wireless charging Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
4, electromagnetic induction. This is the most common way wireless chargers work, which uses the principle of electromagnetic induction to generate current through electromagnetic induction between the primary and secondary coils, so as to achieve the transfer of energy in the space. Radio waves.
5, radio wave transmission technology: the technology is to convert electromagnetic waves into current, and then through the circuit to transmit current for charging. The radio wave transmission system mainly consists of microwave transmitter and microwave receiver. The microwave transmitter emits radio waves, and the microwave receiver captures the radio wave energy and adjusts it with the load to get a stable straightIt's running.
