Does fast-charge technology affect battery life?

This is probably the majority of users are most concerned about, no matter how developers hype, the user is still most concerned about the impact of their mobile phones, especially battery life.

First put the conclusion that the current fast-charging technology is an impact on battery life, but do not have to worry too much, because you may not use the battery life end and will replace for the phone.

And then to analyze why, now the vast majority of mobile phone batteries on the market is still a lithium battery. Today's fast charge technology, whether it is QC2.0, PEP or VOOC, the phenomenon of heating in the charge can not be completely avoided, the difference lies only slightly or serious.

For lithium batteries, high temperature work in addition to the normal charge and discharge, Inevitably accompanied by some side reactions, such as electrolyte decomposition, the electrode generated deposits and so on. These have a battery life on both the impact of large and small. The maximum capacity of the battery, battery power display will be the result of these side effects are affected. As for the size of the impact naturally with the degree of heat and different.

However, the safety of fast charge technology can be guaranteed, first, as mentioned at the beginning of the 

current size relative to the technology is not very high, the second is the developer in the development of fast 

charge technology will also charge the internal, mobile phone internal even within the battery to adjust accordingly to adapt to a larger current, but also set different protection measures to ensure safety, so this can be assured. Of course, the premise is the user's normal use of the original charger and battery. 

Several functions of Battery BMS

(1) Accurate estimation of SOC:

Accurate estimation of the state of charge (SOC) of the power battery, that is the remaining battery power, to ensure that the SOC is maintained within a reasonable range to prevent over-charging or over-discharging damage to the battery and display the remaining power of energy storage battery. The state of charge of an energy storage battery.

(2) dynamic monitoring:

In the battery charge and discharge process, real-time collection of batteries in each battery terminal voltage and temperature, charge and discharge current and the total voltage of the battery pack, to prevent the battery overcharge or over discharge phenomenon. At the same time can give the battery condition in time, pick out the question battery , to maintain the reliability and efficiency of the entire battery operation, so that the realization of residual power estimation model possible. In addition, the use of historical records of each battery, but also for the further optimization and development of new electric, charger, motor and other information to provide a basis for offline analysis of system failure.

The battery charge and discharge process will usually use more accurate and more stable current sensor for real-time detection, the general current according to the BMS front-end current of different sizes, to select the appropriate sensor range for close to 400A, Open-loop principle, domestic and foreign manufacturers are able to bear low temperature, high temperature, strong earthquake JCE400-ASS current sensor, select the sensor need to meet the high precision, fast response time.

(3) the balance between the battery:

That is single battery balanced charge, so that the battery pack in all the batteries have reached a state of equilibrium. Equilibrium technology is currently the world is committed to research and development of a battery energy management system of key technologies.
