This article gives you a talk about the price of wireless mobile phone fast charge, as well as the corresponding knowledge points of wireless mobile phone fast charge price, I hope to help you, don't forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Ohai Technology: Fast charge wireless charging isFuture
1, 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.
2, AohaiTechnology: Wireless charging leader, is a focus on intelligent terminal charging and storage products research and development, 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.
3, 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 due to the company's experience in the metal precision structure has been precipitated, the company's management has proposedPlan to expand the company's antenna design and manufacturing technology to wireless charging, NFC, smart home and other product fields.
1, due to the heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging. After all, the cable is almost fullAfter the development to 120W, most mobile phones equipped with fast charge are more than 60W, has exceeded the wireless fast charge, so wireless charging because of the technical requirements of the equipment, has gradually opened the gap with wired fast charge.
2, charging power limited, charging technology is not interoperable between different brands of the current mobile phone power upgrade quickly, a day to increase a power, from the original 18W fast charge into a variety of fast charge power, 30W, 45W, 65W, and now there are 120W super fast charge power, This also leads to a lot of wireless charging boards in the current world, such asIf you choose the wrong one, you can't experience the full charging power.
3, in addition to the trouble of charging, wireless charging also has a serious defect, that is, the charging efficiency is too low (early products). There is also a heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, manufacturers have to control the power. 4, because there is a heating problem in the electromagnetic conversion process, taking into account the safety of electricity and other factors, so in 2021, China's Ministry of Industry and Information Technology issued a technical requirement for wireless charging equipment, which has a clear provision: wireless charging rated power must notMore than 50W. In order to comply with this regulation, manufacturers have to control the power. This is also a reason for the gradual disappearance of wireless charging.
5, that is, the power of the universal charge is particularly large, many people who have used the universal charge know that their mobile phone battery is more and more charged, the more charge is less and less, originally full of 100% can be used for two hours, but to the back, it may only be used for half an hour.
6, the 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 has a structureThe oto Edge (2023) comes standard with a 5100mAh battery and supports up to 68W wired charging, 15W wireless charging and 5W wireless reverse charging.
Support 120Hz refresh rate, the body uses a metal frame (armored aluminum), a total of four colors to choose from, the weight of about 195g. Powered by Qualcomm Snapdragon 8 Gen2 for Galaxy (4nm) processor. In terms of battery and charging, it is equipped with 5000mAh battery, which supports up to 45W wired charging and 10W wireless charging.
The fast charging function needs to be met on the mobile phoneThree elements, all three are indispensable. Charger, Battery, chargeIC. The charger needs to meet sufficient output current and output voltage, because the charger line has a large parasitic resistance, if you want to achieve a large charging current, the on-load output voltage of the charger needs to be higher.
The introduction of wireless mobile phone fast charge price is here, thank you for taking the time to read the content of the site, more about the price of wireless mobile phone fast charge, wireless mobile phone fast charge price information don't forget to find oh in the site.
