1, wide impedance range, to meet a variety of needs the inductance of the wireless charging coil is usually at the micro hen level, the test frequency is in the kHz range, which requires a wide and accurate measurement range. The E4980A/AL has a wide impedance range from 4 milliohm to 100 milliohm, and can cover this band with 10% accuracy, making it particularly suitable for the precise evaluation of wireless charging coils.
2, the secondary winding is broken, the wireless charging coil has two windings, one is the main winding, one is the secondary winding, after the secondary winding is damaged, it will lead to the main winding hotWhile the output has no voltage.
3, wireless charging coil test coil capacitance to the ground because the capacitor is the electric field energy and magnetic field energy conversion material, in the process of wireless charging, electric field energy and magnetic field energy need to be converted. The process of wireless charging is the transmission of electric energy from the charging device to the receiving device.
4, Wireless charging is also known as wireless Power supply WPT (Wireless Power Transmission), is a coupled electromagnetic field as the medium to achieve electrical energy transmission. For electric vehicles, wireless charging is mostly through a power supply coil arranged on the groundAnd the electric coil at the bottom of the vehicle, through the magnetic resonance generated between the coils to replace the traditional power lines to charge the vehicle. This charging method requires higher spacing between the supply and receiving coils.
1, Samsung s6edge wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone. The S6 Edge features are as follows: Fast photos with large aperture: A 5-megapixel front-facing camera and 1600The rear megapixel camera, all equipped with an F9 aperture and high-resolution sensor, allows you to take sharper photos no matter where you are. 2, about the price, the official price of Samsung wireless charger is 499 US dollars (about 310 yuan), some buyers may get a free. For the charging speed, the Samsung S6 uses high-efficiency wireless charging technology, which can be filled in 3 hours, which is comparable to the traditional wired charging speed. Fast charging is more practical, providing four hours of battery life in just 10 minutes.
3, Samsung Galaxy S6 powerful configuration, equipped with ExynoCharging time is long and charging is slow, and wireless charging can be done at night when the phone is not used. This wired charging will be better, some, because you wired charging, it will charge more efficiently, wireless charging, it will be slower. There is nothing good or bad.
Apple mobile phone general we are better with direct charging, its charging effect is also a direct point, wireless charging is now a relatively novel way, but I still accept wired charging is better. I always feel that the money will charge the efficiency of the battery will be higher. The iPhone12 can be charged wirelessly or via wired.
Apple straight. Direct charge can be charged fast, but also can play at the same time, wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. However, the conversion efficiency is best at about 80%, and the remaining electrical energy can only be converted into heat, so the heat of wireless charging has been a big problem. High-power wireless chargers also need to be paired with active cooling fans.
Apple straight. Direct charge can be charged fast, but also can play at the same time, wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. The iPhone uses lithium-ion batteries, which have a chargeIt is fast, durable, and has advantages such as higher power density and the ability to provide longer battery life in a lighter volume.
I think Apple mobile phone or wired charge is better, or more convenient, if you use wireless charging, in fact, in the wireless charging device to the back of the plug a wired charge power line, it can be energized, so I think wireless charging is still a chicken fin a product, It's just that you don't have to plug your phone into a charging port every time.
Apple cable charge well. The advantage of magnetic absorption is that it can be adsorbed near, and adsorption can be chargedThe charger automatically aligns the position of the charging coil, which solves the problem of manual alignment for traditional wireless charging; But it is still a wired form, and the power is not as good as wired charging, so the key moment or wired charging is more realistic. If the MagSafe magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.

Reason 1 Wireless charging quality : charger problem First Wireless charging quality , if you noneThe Apple 8plus can not be charged wirelessly, you need to check whether the charger is working properly. Sometimes, the charger may malfunction or be damaged, resulting in normal charging. If this happens to your charger, you will need to replace it with a new charger.
One: Test with a wireless charger This is the most simple and direct method, put the phone on the wireless charger, if the charging is displayed, it means that the wireless charging function is not supported. This test is because the current market wireless charging mobile phones and chargers are compatible with the QI protocol, canLet go and charge.
You can check whether your phone supports wireless charging in the following ways: Test with a wireless charger This is the simplest and most direct way, put the phone on the wireless charger, if the charging is displayed, it means that it has wireless charging function, and vice versa.
Apple mobile phone can not charge may be the reason for the charging interface, you need to check whether the charging interface is abnormal, it may also be the charging source or the data line is damaged, you can use its wireless charging quality his charging equipment to try, the temperature is too lowIf the charging fails, the phone can be charged in a warm place, or the phone can be sent to Apple's authorized service for detection and repair.
The iphone8plus wireless charger needs to be purchased separately. Wireless charging uses magnetic induction to charge the iPhone 8 Plus. The iPhone does not charge wirelessly when connected to USB. If your iPhone8 Plus uses USB to connect to your computer, or connects to a USB power adapter, the iPhone8 Plus will use USB Connect and charge.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the AC mains at the input end is converted by the full bridge rectifier circuitDirect current, or use 24V DC terminal directly to supply power to the system. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Wireless charging is also called inductive charging, non-connectionTouch inductive charging, derived from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
