Many netizens expressed hope that other regions could follow suit. Very convenient As netizens said, this new street lamp is very convenient.
In the bustling Wuhan Jianghan Road, you do not need to worry about the problem of mobile phone battery. Surprised to tell you that wireless charging has been in the street lamp steps of Jianghan RoadThe top quietly appeared. Just out of the subway, you can find them in about 60 street lights, each lamp has 2 charging points, support high-power wireless fast charging. Many citizens have tried it and praised its novelty and convenience.
According to the introduction of the staff, there are currently more than 60 rechargeable street lights open to the public, each street light has two places to charge, high-power wireless fast charge. Advantages of rechargeable street lights. The development of science and technology can always bring surprises to life. The emergence of this high-tech street lamp has greatly improved people's understanding of new things, and it is also more conducive to people's acceptance. Many netizens joked toAfter no longer afraid of shopping when unable to pay.
1, however, wireless fast charging does not directly lead to reduced 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 wireless flash charging technology to passSeries double cell and air-cooled cooling technology, taking into account the charging efficiency and safety.
2, factors affecting battery life Although some people worry that wireless fast charging will damage 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.
3, in theory, wireless fast charge and mobile phone fast charge, are specifically designed for mobile phones, mobile phone battery is no harm toThis is something that needs to be understood. 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.
4, This feature will not have any negative impact 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.
5Wireless charging bank has no harm to mobile phone battery. Because the working frequency of wireless charging is now below 1M, it will not affect the signal of the mobile phone. On the contrary, wireless chargers not only reduce the use of data cables, but also make charging methods more free and safer. It is basically the same as wired charging, but the rate is lower, but the wireless charger still has a high energy conversion rate, which saves energy consumption more.
6, electromagnetic induction, magnetic resonance, wireless fast charge will not affect the life of the battery.
Principle of electromagnetic induction, magnetic resonance, electric field coupling wireless charging to charge the mobile phone. Most of the wireless charging on the market now uses electromagnetic induction, which is a widely used technology. The efficiency of charging is very fast. Many of the original accessories of the electronics factory are using this principle, and now we see that most of the Apple mobile phones on the market have this function.
The mobile phone can not be moved, as long as the wireless charger is used to charge, then the location of the mobile phone must be very regular, if it is accidentally touched, then it can not be charged, especially before going to bed at nightCharged, accidentally touched when sleeping, or other reasons lead to the position is not fit, and then get up in the morning to find that the phone is not charged, think about it is really quite a headache.
Wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
There are two coils on the phone that create a magnetic field when the charging pad is turned on. The coils on the phone generate communicationElectricity, and then convert alternating current into direct current, we can charge the phone. Although the charging principle is simple, the manufacturing process is really complex and not as simple as we can currently imagine. First of all, the distance of wireless charging is too short, and the effect of wired charging is no different.
Insert the interface end of the wireless charging receiver as shown in the picture into the charging hole of the phone, just like wired charging. Then place the receiver patch on the back of the phone. Once plugged in, you can proceed to the next step. Now connect the QI wireless charger to the socket so that it is inPower working state.
