402030 polymer battery

　　What impact does fast charging have on the 402030 polymer battery?

　　I believe that mobile phones have become the favorite of most people nowadays, and if the 402030 polymer battery of the mobile phone drops below 20%, everyone will probably have some bad emotions, such as restlessness. After all, it is like going out without taking it. Just like wallets, mobile phones that easily run out of 402030 polymer battery have become an object of anxiety for everyone nowadays. Mobile phone manufacturers naturally understand this, so they respond to the needs of the majority of users. After all, users are the foundation. Without users, who will buy mobile phones? Therefore, the fast charging function came into being. It is not an exaggeration to say that fast charging is the greatest invention in recent years. Many people will never go back to fast charging after using it. Nowadays, thousands of yuan phones have begun to come standard. This technology was developed, but another problem arose at this time.

　　What is in front of people now may not be how fast the charging speed of mobile phones is. After all, Xiaomi has developed 100W fast charging, and 40W fast charging is also available everywhere. Wireless charging has already achieved 20W, and now even a thousand yuan All mobile phones are beginning to use fast charging technology. Under normal circumstances, the use of these once high-end technologies in thousand-yuan machines can only mean that their costs have been reduced, so these technologies can be popularized. As the number of users increases, there will be another problem. The chargers that everyone has used are basically 5V1A specifications, not to mention Apple. 1A chargers have been used for several generations, but in the era of fast charging, charging with various parameters Now that they have all the devices, consumers will inevitably have questions at this time. Will the parameters become larger, will it damage the 402030 polymer battery? After all, the batteries of mobile phones today are not replaceable, unlike in the past. Here we will introduce several major directions of today’s fast charging technology.

　　Nowadays, there are actually two main methods to improve charging speed, which are also the two general directions today:

　　1. Increase the voltage. Increasing the voltage requires higher quality of the charger. The charger will generate a lot of heat during the charging process, so if the charger does not meet the standards, it may be dangerous.

　　2. Increasing the current means lowering the voltage to increase the current. However, large current also has disadvantages. For example, it will accelerate the aging of the 402030 polymer battery and bring certain safety hazards, and large current will also cause damage to the chemical substances inside the lithium 402030 polymer battery. Irreversible loss, but it also has advantages, that is, low heat generation. It depends on the manufacturer how to balance the relationship.

　　But fast charging technology all needs to meet three conditions, that is, the three indispensable links: charger, 402030 polymer battery, and chargeIC. The fast charging technology that increases the current usually requires additional customization of the charging cable. Because the current is large and there are no certain standards, it will cause harm to the human body.

　　For now, mobile phone fast charging technology is mainly divided into the following three categories:

　　1. VOOC technology, its core is low voltage and high current.

　　2. Qualcomm QuickCharge technology, its core is high voltage and low current.

　　3. MediaTek PumpExpressPlus technology allows the charger to determine the voltage based on current and can be dynamically adjusted.

　　Fast charging technology is fully popular! It comes standard with a thousand-yuan phone, but will it damage the 402030 polymer battery?
