1, novelty, good user experience. (5) Safety, with a variety of protection functions, such as: overcharge and overdischarge, metal foreign body detection and other functions, always protect the user's personal property insurance safety. (1) Wireless charger charging transmission distance is short, the effective transmission distance is usually within 10mm.
2, the use of wireless charging function must first determine whether the mobile phone supports wireless charging, followed by the need to buy a wireless charger compatible with the mobile phone. Using a wireless charger first requires connecting it to a power source. Then place the phone in the center of the chargerNo exposure, so it will not be eroded by moisture and oxygen in the air; There is no contact, so there is no loss caused by mechanical wear and flaring during connection and separation.
2, the biggest advantage of wireless charging is convenient. Wireless charging has little impact on mobile phones, but when all electronic products support wireless charging, the convenience brought to users is more interesting. Apple says future models of AirPods wireless headphones will come with AirPower-enabled charging cases, so users can charge them simply by placing them on a charging pad.
3, advantages: use noLine magnetic induction charging equipment can be invisible, the equipment wear rate is low, the application range is wide, and the public charging area is relatively reduced; High technical content, easy to operate, can implement relatively long distance radio energy conversion. Disadvantages: Although the equipment has high technical content, the economic cost of the equipment is higher and the maintenance cost is large; Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high.
Convenience: Wireless charging of mobile phones eliminates the trouble of using a charging cable. 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 analyze the advantages and disadvantages of wireless charging to help users better understand this charging method. Effective charging distance is limitedThe effective charging distance of the former 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, and a family can buy a charger to meet the needs of the whole family.
1, the wireless charging system mainly uses 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.
2, 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. System workStronger and more concentrated, this is called the "current magnetic effect".
4, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones 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. As shown below.
