This article gives you a talk about wireless fast charging, and wireless fast charging does not charge the corresponding knowledge points, I hope to help you, do not forget to collect the site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Now wireless charging can be seen everywhere, so what is the principle of wireless charging?
2, electromagnetic induction type: The fundamental principle is the use of electromagnetic induction principle, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring the energy from the transmission end to the receiving end. High conversion efficiency, madeThe price is cheap, but the transmission distance is short and easy to be affected by the placement.
3, 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.
4, wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. wirelessIt reduces the complexity of plugging and unplugging data cables and the damage to the charging interface. Mobile phone fast charging is mainly divided into three categories: VOOC flash charge fast charging technology, Qualcomm QuickCharge0 fast charging technology, Mediatek PumpExpressPlus fast charging technology.
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 are properly "used with charge"Which is good for battery health.Unqualified third-party power adapters and data connection cables do not have overvoltage and overcurrent protection, which may cause unstable charging power and battery damage. The official recommendation is 0 ° C ~35 ° C is the ideal working environment for iPhone, too high or too low temperature will have a certain impact on the phone battery.
However, wireless 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, OPPO Ace2 uses 40W noneLine flash charging technology, through series double cell and air cooling cooling technology, taking into account the charging efficiency and safety.
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 does a better job of controlling temperature and power conversion, and the impact on the battery can be controlled as long as the quality of the device is reliable. Wireless fast charge is especially suitable for those who pursue convenience, such as busy office workers.
In theory, wireless fast charging and mobile phone fast charging, are for mobile phonesDoor design, 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 answer, of course, is no. So why would anyone think that wireless fast charging would hurt phones? Mainly due to the concern of frequent charging, the biggest benefit of wireless charging is that it is free from the bondage of the cable, and it is ready to take and put each charge, reducing the cumbersome plugging and unplugging of the data cable more than the damage to the charging interface, but there are many users who frequently charge and power off will reduce their handsService life of the machine.
We need to pay attention to is that most of the mobile phone life is two or three years. Under such a damage curve, within the basic life of the mobile phone, the use of fast charge will not have much impact on the battery life of the mobile phone. So we can think that, in fact, the use of mobile phone fast charge will not cause too much loss to the mobile phone battery, at least within the national standard is enough for us to use.
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. 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. Output through the power management moduleThe direct current is converted into high frequency alternating current by 2M active crystal oscillator inverter to supply the primary winding.
3, the principle of wireless charging 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 device.
4, 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.
5, electromagnetic induction: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring the energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short and easy to bearThe location affects the display.
If it is a simple wireless charging base there is no storage function, it is equivalent to our commonly used mobile phone charger, but it is wireless charging, the phone can start charging on it. Wireless chargers generally have 5W and 10W fast charge.
Millet wireless charger can store electricity, millet wireless charger can not store electricity, because it is not the same as the charging treasure, it just turns the previous wired charging into wirelessCharging, we do not need to find a data cable to plug into the charging interface of the phone to achieve charging, it is necessary to use the charging head to connect to the power supply to use, can not store electricity as a charging treasure.
Wireless charger needs to be connected to the power, if you want to do not connect to the power of wireless charging, you can choose a wireless charging treasure, search YMP wireless charging treasure can find a lot, always have a wireless charging treasure in the bag, no longer need to take the charging line when you go out, as long as the mobile phone and wireless charging treasure together, the mobile phone is automatically in a charging state, Very easy to use.
The mobile power supply is the batteryWireless charging is a charger that can be used with mobile power at any time.
First of all, there is no virtual charge of the wireless charger, you said that this situation should be the wireless charger charging cut-off voltage is inaccurate, lower than the normal 5V standard voltage, so it looks like the battery has been fully charged, the actual is not full, there is another situation is the wireless charger in the entry of small current charging, At this time, looking at the charging indicator light has changed color to show full, actually still charging.
Wireless charger charge a night will not hurt the mobile phone, now the mobile phone is lithium battery, not the previous lead-acid battery. closeThe machine will power off automatically when it is fully charged. 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 chargers need to be connected to a power supply if you want to be wireless without connecting to a power supplyCharging, you can choose a wireless charging treasure, search YMP wireless charging treasure can find a lot, a wireless charging treasure in the bag, no longer need to take the charging line when you go out, as long as the mobile phone and wireless charging treasure together, the mobile phone is automatically in a charging state, very convenient to use.
Wireless charger can be plugged into the power supply, the wireless charger is designed to be easy to use, but if the user does not use the wireless charger when charging, it is best to choose to turn off the power.
Always plugged into the power supply is standby state, ready to charge at any time. It's not recommended to stick it in.
Wireless charging does not require frequent unplugging. The wireless charger can always be plugged into the power supply, the only disadvantage is that it will consume more power, and the life of the charger will be shortened a lot. The wireless charger is a device that uses the principle of electromagnetic induction to charge, and its principle is similar to that of a transformer.
