2, electric vehicle wireless charging technology mainly uses the mutual inductance in the law of electromagnetic induction. It is also similar to a transformer, which inputs from the primary coil and then generates an induced current on the secondary coil. It mainly relies on the energy transmission between electricity and electricity, converts electricity into magnetism, and then induces electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires.
3, wireless charger use method: the mobile phone standard charger and data cable connected to the wireless charger, and then handThe machine is placed in the center of the wireless charger base, wireless charging can be realized, the indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick.
4, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. 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.
1, At present, the wireless charging market is mainly competed by A4WP, PMA and WPC (Qi standard) three camps. However, the decision by A4WP and PMA means that wireless charging devices based on their respective standards will be compatible with each other's phones, greatly broadening the scope of application of devices. Although there are no details on the compatibility of older products to the new standard, this development is certainly a positive sign.
2, also is the electromagnetic induction PThe main difference between LA and Qi is that PLA uses existing accessories to make a difference on the battery, so every mobile phone can achieve wireless charging through PLA, while Qi is directly integrated inside the phone. 3, support wireless charging mobile phones are very many, in addition to the traditional Samsung, Apple, Huawei's three flagship, Xiaomi is the most active in wireless charging, wireless charging technology is also ahead of others a big cut. 4, in the Android camp, Samsung is one of the early adopters of wireless charging technology. Several models of its Galaxy S series and Note seriesAll machines support wireless charging, such as Galaxy SS2S22 series and Note Note 20. In addition, some models of Huawei Mate series, P series, Xiaomi Mi Mix series, Mi 10 series, and some models of OPPO and vivo have also joined the wireless charging function.
5, Huawei P30Pro also supports wireless charging on Huawei P30Pro, and Huawei P30Pro battery capacity also reached 4200mAh, in order to bring more lasting battery life, while the phone also joined a new generation? '> Mi 9 mobile phone inside, wireless charging coil is broken, how much money can be repaired? Hello! Send the general mobile phone repair shop 100 yuan. The phone's insured. It's free.
-120. Generally, the cost of replacing an original wiring (wiring cost) is about 80-100, and the new machine is more expensive plus the manual cost of changing the wiring is generally 10-20 yuan. If you change the assembly line, the cost is 5-10 yuan, and the manual fee is also 10-20 yuan.

Convenience: Wireless charging of mobile phones eliminates the trouble of using charging cables. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging.
However, wireless charging still has some limitations and inconveniences. This article will be about wireless chargingThe advantages and disadvantages are analyzed to help users better understand this charging method. At present, the effective charging distance of wireless charging technology is still limited, and the phone needs to be placed on a device that supports charging. Wireless charging may lead to accelerated battery wear and shorten battery life.
Convenience: non-contact, one-to-many charging compared with the general charger, reduces the trouble of plugging, but also avoids the interface is not applicable, poor contact and other phenomenon, the elderly can also be very convenient to use. (2) Versatility: a charger can charge multiple loads, oneA family can buy a charger for the whole family to use.
First of all, the wireless charging efficiency is slightly low, the early equipment heating problem is serious, resulting in the back of the mobile phone hot, manufacturers have to make compromises on power control. (Balancing safety and efficiency was a challenge in the early days of wireless charging.) Second, wireless charging bases often require additional purchases and are expensive, sacrificing portability. (The trade-off between extra cost and convenience is a big consideration for users.
The efficiency is slightly lower: the general charger also has a transformer, but the wireless charging is composed of a transmitting coil and a receiving coil becauseThere are limitations in the structure, and the efficiency of energy transmission is theoretically lower than that of ordinary chargers. Slow charging speed: Because most of the current receiving products such as mobile phones limit the input power, the charging speed is relatively slow.
Disadvantages of wireless charging: can not charge while playing: the current wireless charger is basically a wireless charger base, there is no fixed position design, mobile phones are difficult to meet the needs of charging while playing. Although there are also vertical wireless chargers that can solve this problem, it will still affect normal use.
2, wireless charging circle to add a vertical because this large circle represents the wireless charging of the magnetic field induction area. After the mobile phone with a protective shell, relying on the built-in magnetic module of the mobile phone is a little powerless, so the built-in magnetic module of the protective shell can make up for the magnetic force.Apple's official transparent case can clearly see the white circle, this is the MagSafe magnetic module.
3, Apple wireless charging interface circle is also called auxiliary touch, small white dot, small circle, virtual home button, the method of opening is as follows: unlock the phone screen, open the phone Settings icon. In the Settings page, swipe down and tap Accessibility. Then scroll down the screen and tap the touch options. Then find and tap the auxiliary touch option.
