Wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology transfers energy through a magnetic field between the charger and the electrical device,There is no wire connection between the two, so the charger and the device that uses electricity can be exposed without conducting contacts.
Wireless fast charge is actually a function, is the short for wireless charging function, but also represents the wireless charger. This charger can not be connected to the socket, very convenient. With the function of fast charging, directly do not need the data cable to charge the phone, only need the user to put the phone near the wireless charger can be charged directly. The following is a detailed example to introduce this wireless charging method.
Wireless fast charge is the use of electromagnetic induction principle, in the sending and receiving endA coil, the sending end of the coil connected to the wired power supply to generate electromagnetic signals, the receiving end of the coil induction electromagnetic signals to generate current to charge the battery, can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat.
Intelligent wireless fast charging is the use of Qi technology (the world's first to promote wireless fast charging technology standardization organization launched the "wireless fast charging" standard), for the vast majority of mobile phones on the market wireless fast charging, perfect match Apple/Samsung/Huawei and other handsWireless fast charging protocol, wireless fast charging efficiency and some mobile phone wired charging efficiency is the same (10W). I installed the East Arrow LUXURIES, the quality and reputation can be.
And now the wireless fast charging technology is more and more developed, most of the mobile phones support the qi standard, that is, the manufacturers will support qi wireless fast charging in the introduction. You need a wireless charging chassis, plus an 18-watt or 30-watt fast charger. The second is that the phone needs to support the function in order to achieve the so-called wireless fast charge. Manufacturers are also working on a development of this technologyApple: It only means that it can be quickly charged, and the specific speed needs to be measured by using 20W and above chargers. Samsung: 10W is accelerated charging, 25W is accelerated fast charging, super fast charging. OPPO: Around 30W is fast charge, 40W is flash charge, and 60W is super flash charge.2. Huawei's Super fast charge ranges from 25W to 100W. As of March 2024, Huawei has launched seven mobile phones supporting 100W super fast charge, which are nova9Pro, nova10Pro, nova11Pro, nova11Ultra, NovA11Ultra, and NovA10Pro.nova1nova12Pro and nova12Ultra.
3, super fast charge: the icon is double Dalian lightning, and the maximum output parameters of the standard charger are 10V/25A, 5V/5A or 5V/5A, 10V/4A, 5V/8A, 20V/25A, 11V/6A, 20V/5A. If your device supports the Super fast charge mode, but the normal charge icon (or fast charge icon) is displayed during charging (1) It is recommended that you use Huawei's official charger and data cable.
4. Demo model: Huawei P50 System version:HarmonyOS 2 Huawei has a variety of super fast charging technologies, including 66W, 40W, and 25W. To achieve the fast charge function, three elements need to be met: charger, battery and charge IC. 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.
5. Huawei's supercharge adopts a 5V5A scheme, so that there is no need to convert the voltage and the current is within the acceptable range, thus achieving a 25W superchargeStage fast charge, efficiency is much higher than 9V2A. This 40W breakthrough is mainly the use of charge pump buck technology, simply said is an efficient buck way, the conversion efficiency is very high, there is no heating problem.
1. Fast charging refers to a charger with a charging current greater than 3A, while the charging current of a 15-watt wireless charging is 3A, no greater than 3A, so it is not fast charging.
2, ①, about the above car wireless charging 10W and 15W areaSpecifically: 10W wireless charge and the 15W with QC0 fast charge.
3, the charger says 15W does not mean the actual use of 15W charging, but also depends on whether your phone supports such a large power, the phone and the charger will negotiate the charging power before charging, if the phone does not support it, it will also use a relatively small power charging.
4, with wireless charger 15 watts. Samsung's s9 phone supports up to 15 watts of fast charge, it can use two charging specifications, one is 5V/2A but only 10 watts; The other is 9V/67A, which is 15 watts, and using the latter is fast charging. The s9 uses the QC0 fast charge protocol, which is an older one, and the current Samsung's new mobile phone S20 supports QC0 up to 25 watts of fast charge power.
5, iphone13pro fast charge to 20w. iPhone13Pro mobile phone supports 20W wired charging, 15W wireless charging, the original packaging box with a USB-C lightning cable, you can buy the original 20W or 15W wired/wireless charger through Apple's official website or Apple retail stores, if you already have the corresponding charger, you do not need to buy it separately. iPhone1The 3pro is a smartphone released by Apple on September 15, 2021.
6, Apple 13 fast charging head is 20 watts or more power Apple 13 built-in lithium-ion rechargeable battery, MagSafe wireless charging power up to 15 watts, Qi wireless charging power up to 75 watts, through USB connection to the computer or power adapter charging can be fast charging, 30 minutes up to 50% power, It uses 20 watts.
1, wireless fast charge is wirelessThe combination of charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro and so on. Wireless charging technology 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.
2, wireless fast charge is actually a function, is the short for wireless charging function, but also represents the wireless charger. This charger can not be connected to the socket, very convenient. With fast chargingIt does not require a data cable to charge the phone directly, but only requires the user to put the phone near the wireless charger. The following is a detailed example to introduce this wireless charging method.
3, wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending end of the coil connected to the wired power supply to generate electromagnetic signal, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to charge the battery, can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss on the battery, and wireless charging technology is more convenientAnd the charging heat is low advantage.
