Electromagnetic induction technology is a representative of the first generation of mobile phone wireless charging, transmitting a certain frequency of alternating current through the primary coil, using electromagnetic induction in the secondary coilGenerate current and realize wireless transmission of energy. However, this technology can only achieve single-to-single, short-distance (within 1cm) charging, the power is limited to 5 watts, and can not achieve single-to-multiple charging like WiFi.
Electric vehicle wireless charging technology is what, detailed introduction of electric vehicle wireless charging technology - electromagnetic induction type electromagnetic induction - the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil clock to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
Electric vehicle wireless charging technology mainly uses the law of electromagnetic inductionMutual inductance. 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.
iNPOFi technology, iNPOFi (" invisible power field ", that is, "invisible energy field") Wireless charging is a new wireless charging technology. Its wireless charging series products use intelligent electrical transmissionWireless charging technology, with no radiation, high energy conversion efficiency, weak thermal effect and other characteristics.
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.
Radio wave type: The principle is to convert environmental electromagnetic waves into current and transmit current through the circuit. The transmission distance of this wireless charging method is greater than 10Devices need to support Qi or other wireless charging standards, and devices that do not support wireless charging technology cannot enjoy its convenience.
2, Apple cable charge well. The advantage of the magnetic magnet is that it can be adsorbated near, and the adsorption can be charged. The charger is automatically aligned with 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.
3, the second noneWire charging, its working principle is the use of electromagnetic induction, wireless charging less line bondage, each charge with the release, compared with wired charging, it does not plug and unplug the data cable cumbersome, so charging is safer, more fast, its disadvantage is that the charge is relatively slow.
Convenience: Wireless charging of mobile phones eliminates the trouble of using charging cables. Users simply place the phone in the charging dockOn, you can start charging without inserting or removing the charging cable. 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.
Advantages of wireless charging safety: no power contact design, you can avoid the danger of electric shock. Durable: the power transmission element is not exposed, 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.
Convenience, especially when charging multiple devices the biggest benefit of wireless charging is convenience. Wireless charging has little impact on mobile phones, but when all electronic products support wireless charging, the convenience brought to users is more interesting. appleFuture models of AirPods wireless headphones will come with AirPower-enabled charging cases, so users can charge them simply by placing them on the charging pad.
Advantages of wireless charging: The use of wireless 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 of wireless charging: Although the technical content of the equipment is high, the economic cost of the equipment is high and the maintenance cost is large.

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.
Wireless charging may cause battery loss to accelerate and shortenBattery life. Slow charging speed Wireless charging speed is relatively slow, temporarily can not be compared with wired charging. Wireless charging requires users to hold a charging board or use a special wireless charging seat, for frequent mobile phone users, charging while using the situation is very common, which may bring some inconvenience to use.
Advantages: non-contact, no wire, movable. Disadvantages: short distance, small power, poor efficiency. Low efficiency: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power.
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 chargerCan be used by the whole family.
Mobile phone wireless charging Because there is no need to plug and unplug the charging cable frequently, the data interface wear of the mobile phone will be reduced a lot. At the same time, the coil of wireless charging of the mobile phone is not exposed to the air, which can also reduce the oxidative corrosion of the charging unit. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed, which is easy to oxidation corrosion. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process.
Flexible charging: Although the wireless charging treasure is a wireless wireless charging advantage , in fact, it is often a wireless charging advantage that will support wired charging, and it is very convenient to choose which one. And it can be used with multiple devices. Disadvantages: slightly slower charging speed: compared with wired charging banks, even with fast charging, the charging speed of wireless charging banks will be slightly slower, especially for devices with large-capacity batteries, and the charging time is longer.
Low charging efficiency: Compared with wired charging, wireless charging is less efficient.That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmit and receive, it may lead to reduced battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge.
Magnetic resonance wireless charging technology is a new type of charging method, which transmits energy through a magnetic field without the use of traditional wired charging equipment. Although this technique has certain advantages, it also has some disadvantages. Conversion of low efficiency magnetic resonance wireless charging technologyThe efficiency is generally only about 70%, which is low compared with wired charging.
