Lithium-ion batteries are widely used, so that the lithium-ion battery charging method has received attention. Regarding different lithium-ion batteries, there is usually a different lithium-ion battery charging method. This is why you can't fully master the charging method of lithium-ion battery in a short time.

In order to help you correctly understand the lithium-ion battery charging method, this paper brings the correct introduction of the mobile phone lithium-ion battery charging method, let's take a look. The battery applied by the mobile phone in our market has now completed the transition from the NiMA nickel-cadmium battery, but most people use the method of lithium ion batteries to stay in the old faults of nickel-hydrogen nickel-cadmium batteries. On the way.

This paper specifically clears the correct use of the most widely used battery lithium-ion battery, and the number of people using the misunderstanding is sampled, and the key to the first three-time charging of the front three times of the mobile phone lithium-ion battery. Since the end of 1990, the lithium ion battery has been rapidly carried out due to its outstanding performance and is widely used in civil society. Lithium-ion batteries are sensitive to other batteries, which is much more sensitive to many categories, such as mobile phones, laptops, small cameras, etc.

, lithium-ion batteries are a kind of aspirational small green power. We often say that the lithium-ion battery is a needle related to traditional nickel-cadmium batteries (Ni / CD) and NiMH batteries (Ni / MH). Has a high-speed recurrence and low discharge rate of high-cycle life, high-speed liquidity.

The basic principle recognized by lithium-ion batteries is now the so-called "rocking chair theory". The charge and discharge of the lithium-ion battery is not a conventional method to end the transfer of electrons. When the child passes through a lithium ion in the crystal of the layer, energy changes occurs.

Under normal charge and discharge conditions, the transportation of lithium ions generally only causes changes in the layer interval without causing damage to the crystal structure, and thus, the lithium-ion battery is a kind of ambitable invertable battery. When charging and discharging, the lithium ion is reciprocated in the battery. It is like a rocking chair to sway in the positive negative pole, so someone is called a lithium-ion battery image as a rocker battery.

Misunderstanding in the daily application of lithium ion batteries. A lot of "activation" issues related to lithium-ion batteries is: Charging time must span 12 hours, repeat three times in order to activate the battery. This "first three charge charges charge 12 hours more", it is obviously the statement from the nickel battery (such as nickel-cadmium and nickel hydrogen).

ਇਸ ਤਰ੍ਹਾਂ ਦੀ ਕਹਾਵਤ, ਤੁਸੀਂ ਕਹਿ ਸਕਦੇ ਹੋ ਕਿ ਸ਼ੁਰੂਆਤ ਦੁਰਵਰਤੋਂ ਹੈ। After sampling investigation, it can be seen that some people confuse the charging method of two batteries. The charging and discharging characteristics of the lithium-ion battery and nickel battery have a large difference, all of which are all severe formal technical information emphasizes overcharge and over-discharge to lithium-ion batteries, especially liquid lithium-ion batteries constitute huge damage.

Therefore, charging is preferably charged in accordance with the specification time and specification method, especially if you don't perform long-term charging across 12 hours. Generally, the charging method introduced in the mobile phone manual is to suit the standard charging method for the mobile phone. In addition, the mobile phone or charger of the lithium-ion battery will actively stop after the battery is full, and there is no "trickle" charging of the nickel electric charger for 10 hours.

That is, it is assumed that your lithium-ion battery is on the full charger is also white charge. And we can't make sure that the battery's charge and discharge protection circuit related features will never be changed and quality, so your battery will be in dangerous edges. This is also another reason for our charging.

Test tables for lithium-ion battery charging cycles, data about the number of cyclic life is listed below: Circulation Shou (10% DOD): 1000 times Circulation Shou (100% DOD): 200 times, DOD is the depth of discharge abbreviation. As can be seen from the table, the number of times the number of times and the discharge depth, the number of cyclic life during 10% DOD is much longer than 100% DOD. Of course, it is assumed to be equivalent to the relative total capacity of practice: 10% * 1000 = 100, 100% * 200 = 200, the complete charge and discharge of the latter is still better.

However, the number of lithium-ion batteries is primarily reflected in the charge and discharge cycle. This cycle is a must-see, 30% electricity, full of electricity, and 70% of electricity, which is full of electricity, this Just is a charging cycle. Therefore, the method of using a lithium ion battery in accordance with the slogan of the inventors of the lithium ion battery.

Extraordinary time charging and complete empty power constitute excessive charging and excessive discharge, will constitute a permanent damage to the lithium ion battery, from the molecular layer, excessive discharge will result in excessive lithium ions in the negative electrode carbon to make the sheet The layer structure has a depression, and excessive charging will take too much lithium ion hard to the negative electrode carbon structure, and some of the lithium ions can never be released. This is also a lithium ion battery generally matches the control circuit with charge and discharge. s reason.

Lithium-ion batteries generally have a handle chip and a charging control chip. There is a series of registers, capacity, temperature, ID, charging status, and the number of discharges. These values ​​will be gradually modified.

Use instructions The premium effect of "Applying for a full charge and discharging one by a month" should be to correct the value in these registers, so that the battery's charging control and nominal capacity meet the practice of battery. The power accounting chip is recorded Curves (voltage, current, time) can sample the battery's electricity, which is what we read in BatteryInformation in the BatteryInformation, and the lithium-ion battery has been changed after multiple times, and the discharge curve will be changed. If the chip has not been The opportunity reads out a complete discharge curve again, and the amount of electricity calculated is not accurate.

So we demand deep charge to calibrate the battery's chip. Pre-three-three charging correct methods and daily use of lithium ion batteries. The time division of the top three charging is completely unnecessary to perform extra time charging such as 12 hours to activate the battery, the charging circuit is originally protected, and it is useless.

During normal operation, complete discharge should be prevented from complete discharge (using black screen and electricity), the best way is to purchase the second battery in time to replace. It is not used for a long time, and it may be repeatedly charged for a while, the method is a complete charge and discharge, and then the battery can be used as soon as long as it is used for a long time. It is assumed that a battery is not necessary, and the charge is charged to 40% to protect the battery.

After all, the primary number of lithium-ion batteries is primarily reflected in the charge and discharge cycle. This cycle is a must-see, 30% electricity, full of electricity, and uses 70% of electricity in the next time. This is just a charging cycle.

When you start charging during normal use: We can often see this: Since the number of charge and discharge is limited, the electric battery should be charged as light as possible. However, this statement is obviously negligent! Under normal conditions, you should reserve the principle of re-recharge if the battery remains in the battery (but must not use shutdown and recharge), assume your battery on your day 2nd, you can adhere to the whole day. You should start charging in time! And when you demand charging, it will lead to a busy important job that will lead to communication.

The power of the battery is not used to fill it, it is not to go to the extreme. One way to spread the same spread as long as the long charging is "Try to use the battery's battery, it is best to take the initiative". This practice is actually just the practice of nickel battery, the purpose is to prevent "remembering effect", unfortunately, it is also spread on the lithium-ion battery.

In the early years, since the prostaining of the mobile phone battery is too low, it still does not charge the continuous use of the active shutdown. Effects this such as the mobile phone has no response in the later charging and boot, have to send the maintenance. This is actually because the battery causes the voltage to be too low due to excessive discharge, so that there is no normal charging and power-on condition.

Practical related experience proves that the discharge depth reaches a 100% lithium-ion battery as a waste rate of 50% (for many years, it has proved that the discharge depth of more than 99% can activate the rectification power supply can be activated, and other pairs of folded!) For lithium ions The correct approach of the battery phone: Attenuation, the most important tips for the charging and discharging of lithium-ion battery mobile phones are: 1. According to the specification, the procedure is charged, that is, the top three times will be done so, first charge the charger (Line charge) Putting the power and then plug in the output of the charger with the mobile phone charging port, some people want to ask: It is boot and charging, still shut down charge? A: You! A small number of mobile phones cannot be charged for the backup battery (small lithium electricity on the motherboard, which is 32.768 clock crystals), as long as the direct charge is charged with direct charge in the standby situation! 2, when there is a low inexpression of the phone, you should start charging in time; the lithium-ion battery is mostly damaged in the absence of over-discharge! 3.

The activation of lithium-ion batteries does not require special methods, and the lithium ion battery will naturally activate during normal use of mobile phones. Assume that you are stubborn to use the first three 12 hours long charging "activation" method, and there will be no effect on practice. Generally speaking, according to the battery capacity size, the charging time is between 2,000 and the charging time is seeking 12 hours of super long charging and uses the lithium-ion battery mobile phone to actively shut down.

It is faulty!.
