1, from the technical mobile phone, the greater the power of the mobile phone to use fast charge, the smaller its battery density, the same volume of the battery, its capacity will be smaller, because in order to ensure the safety of the battery, support high-power charging of the battery density can not be too large, which will be very dangerous, so the power of fast charge support greater, can only be reducedLow battery density, which makes the capacity of the battery smaller at the same volume, if you want to increase the large pool capacity can only increase the volume of the battery.
2, of course, the higher the charging efficiency of the mobile phone, the better, but the charging power is not so, because the higher the charging power, the faster the charging speed in theory, but this is not proportional. And the charging power is too large, it will also have some safety problems, it should be controlled in a reasonable range.
3, the specific reasons are as follows: If you look at it from the perspective of experience, it must be a fast mobile phone charge, it charges faster. But if from electricityFrom a pool maintenance point of view, slow charging is better for battery life.
4, w faster than 66w and no harm, in general, the higher the power of the charger, the faster its charging speed, according to this standard, if the charging speed of 100 watts and 66 watts, in the case of the same technical principles and standards, 100 watts of charging speed much faster. The higher the number, the faster the charging speed, the better.
5, the reason why fast charging will affect the battery life of the mobile phone, the main reason is to improve the power, charging will bring more heat than slow chargingWhile high temperatures will accelerate battery aging. However, it is good that manufacturers have optimized and improved the heating problem of fast charge through technical means. And now the mobile phone battery is relatively cheap, if the user wants to have a better charging experience, the basic can ignore the shortcomings of fast charging.
Electromagnetic induction charging, very simple, and the principle of electromagnetic induction in high school is similar, the charging base and terminal used for wireless charging are built-in coils, so that the two are close to the convenienceStart supplying power from the charging seat to the terminal. Many wireless charging mobile phones are this principle, but the location must be relatively uniform in order to charge efficiently. And there is also coupling radiation problem, electromagnetic wave coupling will not exist a large magnetic field leakage.
There are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market mainly Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology five. Let's take a look at the principle of wireless charging.
Electromagnetic induction charging technology: This wireless charging technology realizes energy transmission through electromagnetic induction principle. A certain distance should be maintained between the charging base and the charging device. Usually, the charging device needs to be placed on the charging base for charging. This technology has high charging efficiency and is suitable for small electronic products such as mobile devices.
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 are no contacts and therefore no mechanical wear during connection and separationAnd the loss caused by jumping fire.
The equipment using wireless magnetic induction charging 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.
Wireless charging technology is a new way of charging, it uses a new type of energy transmission technology - wireless power supply technology. The technology allows the charger to get rid of the limitations of the line and achieve electrical and electricalThe source is completely separated. It shows better advantages than traditional chargers in terms of safety and flexibility. At present, there are four main technical ways to achieve wireless charging: magnetic induction technology, magnetic resonance technology, microwave technology and electric field coupling technology.
