Introduction of new notebook battery charging error

How long does it take to charge a new laptop? Perhaps most businesses will warn you to "three charge three", that is, the first three times to be full of 12 hours, and battery power to continue to recharge. This is not a scientific statement, it turns out that such a practice is not scientific, then how to charge a new notebook, what is the difference in time? The author of the work of the notebook battery to give you a detailed answer.

1. To facilitate the understanding of everyone, first look at the operating principle of the 2-cell battery. As shown in the picture: intact batteries, capacity and design capacity are basically consistent, did not do the state of ruler correction. The red line represents the ruler line, assuming that each battery has 100w/h capacity, now the total capacity of 2 power-saving core is 200w/h.

2, the use of a period of time, assuming that only a small number of energy-saving core aging, then did not do the state of the ruler correction at this time the actual capacity of 180w/h.

3.2 battery correction, theoretically should be corrected results ~ In accordance with the correction set, the protection of electricity will be in accordance with the worst battery state balance, when the corrected capacity will become 160w/h, than the 20w/h before the correction.

4. Assuming that in the process of correcting 2 batteries, due to a large discharge, resulting in a further reduction in the number of 1th battery. The main is to revise the time also carries on the heavy load use and so on. In accordance with the "barrel principle", the battery protection chip in accordance with the worst of the 1th number of batteries to balance, when the total capacity is 100w/h. At this time in fact, the capacity of No. 2nd Battery has no obvious loss, but because of the status of the 1th electric Core, 2nd is actually in the state will never be full, unless the 1th electric core return to normal, otherwise, the power of the No. 2nd battery will never be restored.

5. Why some corrections can increase the power of the problem. Look at the picture, the green is the internal parameters of the battery, red is the actual loss of your battery parameters (the head of the curve should be straight, but office Kung fu is not good, curved line), so, under specific conditions, the implementation of rigorous ruler correction will show the increase in electricity.

6, the so-called "three full charge discharge" is how to come. In fact, from selling batteries for batteries, of course, the early nickel cadmium and other battery needs, but now are lithium batteries. Look at the picture to speak, this is after the core, did not carry out a thorough charge discharge of the battery, if there are 4 batteries, do not carry out the so-called "three charge three", the core will be in a number of rotary contact suddenly off.

7. After "Three charge three", the status of the battery in accordance with the worst of the batteries to balance ~ ~ ~

8. Battery power off interpretation, generally in the last 15% suddenly fell to 5% can be considered normal, because each household appliance core manufacturer's process is different, because the final electricity consumption is big, the residual electricity quantity is small, the lithium ion movement is obstructed, appears the surface battery off electricity phenomenon, this phenomenon will be carried out the normal ruler correction to solve. Of course, this phenomenon is also related to the batch of batteries.
