Wireless chargingThe principle of electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
Wireless charging, also known as inductive charging, non-contact inductive charging, 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 timeFor its own operational purposes.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, there is support in mobile phones, electric vehicles, smart furniture and other fieldsLine charging products. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
Wireless charging principle is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end will create eddy currents in the magnetic field, and the receiving coil at the mobile device end will sense this eddy currents. In this way, power is transferred from the charger to the mobile deviceCharging 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 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.
In general, wireless fast charging is a wireless charging method based on magnetic resonance, electromagnetic induction and other technologies, which eliminates the tedious operation of wired charging and brings more convenient and efficient charging to usersThe electric experience. Its wide application and continuous technological development indicate that wireless fast charging will become the mainstream way of charging electronic devices in the future.
wmax wireless fast charge is the abbreviation of wireless charging function, but also represents the wireless charger. This charger can not be connected to the socket, very convenient. It has the function of fast charging. 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.
Factors affecting battery life Although some people worry that wireless fast charging will harm battery life, in fact, wireless fast charging itself will not. Battery life is affected by a variety of factors, such as faulty charging habits (excessive discharge and frequent charging), high temperatures, and non-compliant charging devices. Lithium batteries have no memory effect, and appropriate "use with charge" is beneficial to battery health.
However, wireless fast charging does not directly lead to shorter battery life. Battery life variesFactors, lithium batteries have no memory effect, frequent charging, power off does not affect. What can really damage a battery are wrong charging habits, high temperatures, and substandard charging equipment. For example, the 40W wireless flash charging technology used by OPPO Ace2 takes into account charging efficiency and safety through series dual cell and air-cooled heat dissipation technology.
This feature does not have any negative effects on the phone. In response to this problem, some people said that they often use fast charge, but the mobile phone battery is very normal, there is no problem. Wireless charging is to reduce people's trouble that the data line is too cumbersome.Now wireless charging without the data line people charging becomes very convenient and simple, so the frequency of people charging will also increase.
In theory, wireless fast charge and mobile phone fast charge, are specifically designed for mobile phones, there is no harm to the mobile phone battery, for this point still need to understand. However, when the user chooses a wireless charger, it is best to choose a charger that is compatible with the mobile phone, or choose a charger produced by a regular manufacturer.
The reasons for fast battery loss are more due to improper use, such as excessive use of mobile phones, the use of unstable chargers, wrong charging habits, and power-consuming operations while charging. Wireless fast charge in control of temperature andPower conversion is done well, as long as the choice of reliable quality equipment, the impact on the battery can be controlled. Wireless fast charge is especially suitable for those who pursue convenience, such as busy office workers.
Long-term use of radio charging will not affect the phone. Wireless charging is characterized by no charging line restrictions, affected by the nickel-metal hydride battery, this battery has memory, the best way to use is to reach the best state of the battery after charging. The wireless charging method does not have the bondage of the line, and takes it with each charge, reducing the complexity of plugging and unplugging the data cable.
NonethelessWireless fast charging does not directly lead to shorter battery life. Battery life is affected by a variety of factors, lithium batteries have no memory effect, frequent charging, power off does not affect. What can really damage a battery are wrong charging habits, high temperatures, and substandard charging equipment. For example, the 40W wireless flash charging technology used by OPPO Ace2 takes into account charging efficiency and safety through series dual cell and air-cooled heat dissipation technology.
First of all, we can tell you that this idea is very incorrect, because the current mobile phone is used, there is no memory effect of lithium batteries, with the use of charge but the activity of lithium batteries can be guaranteedIt's better to be durable.
