Meizu double battery fast charging patent

I believe that most people get into the habit of charging their mobile phones all night when they fall asleep at night. After all, the experience of slow charging of mobile phones in the past made most people form such a habit. Recently, about "Isn't it good to charge the mobile phone overnight?" It was flooded with hot searches in Weibo, and netizens also launched related discussions. According to authoritative professors at home and abroad, "When the mobile phone is charged to 100%, the battery does have some reactions, but it will not cause substantial damage to the battery. If you want to better protect the battery, it is recommended to recycle 30-80%, and unplug it when it is charged to 90% at most. This is the best way to extend battery life. "

It can be seen that users can rest assured to charge their mobile phones overnight, but it is best to avoid the experience of playing while charging. As mentioned above, most of this habit still stems from the fact that the charging power of mobile phones is small in the past, and it takes a long time for mobile phones to be fully charged. Nowadays, a number of domestic mobile phones have successfully brought all kinds of high-power fast charging to consumers, and the charging safety has also been guaranteed. For example, the domestic brand OPPO has quite good performance in this field.

Take the popular OPPO Reno6 series as an example. All models come standard with 65W high-power super flash charging, which is safe in speed. It takes less than 40 minutes for a mobile phone with 4500mAh battery to charge from 0% to 100%. Basically, a meal and a bath will make you full of blood, so that your mobile phone can be fully charged before going to bed. In addition, for example, OPPO uses a new semiconductor material in the industry-GaN. As the third generation semiconductor, this material can not only improve the charging efficiency, but also reduce the heat, further reduce the size of the adapter and bring a lighter charging experience.

Of course, with such a fast charging speed, manufacturers have also made great efforts in safety. Like OPPO's 65W SuperVOOC 2.0 super flash charging, thanks to the advantages of low voltage and high current, it will not lead to overheating of the fuselage while charging and playing, ensuring the charging efficiency and putting safety first. Moreover, because the OPPO Reno6 series and other models all adopt the design of double batteries in series, it can provide the best charging efficiency from the beginning; When discharging, the charge pump can be used to halve the voltage of two batteries; This design can make OPPO customized charge pump get the best working mode and the highest charging efficiency.

At the same time, OPPO's 65W super flash charging also uses power adapters, wires and mobile phones to set up five-fold security protection. The charging and discharging of battery circuits are separated by the structure of double batteries in series, which shortens the charging path, further reduces the internal resistance and has higher charging efficiency. In the process of battery discharge, the 65W super flash adopts the charge pump voltage reduction technology, which makes the voltage of the double batteries halved and reaches the voltage that can supply power to the mobile phone. These technologies ensure the charging speed and safety of mobile phones.
