Does regular use of Super Fast Charging damage to the battery?

Generally speaking, super fast charging is not harmful to the battery, super fast charging is a new technology, if the new technology will damage the battery life, that is, the technology with obvious defects is impossible to put into the market, but there should be a little damage.

And most of the current batteries are lithium batteries, and lithium batteries are not memory effect problems, if you wait until all the electricity is used up and then charged, it will make the chemicals inside the lithium battery unable to react and reduce the life, the best way is to charge it when there is nothing to do, so that it can be kept in the best full state anytime and anywhere, so that your battery can be used, long and long.

This is information from the manufacturer, so don't worry.

Yes! The damage to the life of the battery is significant. Because charging too fast will damage the battery.

Let's take my family's situation as an example. My family used to have a small tram with two tires, because it was charged with the matching charger, my brother always thought that the charging time was too long, so he used the larger charger to charge the battery, and the result was much faster. However, after half a year of use, the battery was completely goodbye to the tram, and there was no storage capacity at all.

So what is fast charging? To put it bluntly, it is fast charging, and mobile phones that can use the fast charging function are generally lithium batteries. Is it safe to fast charge your phone?

Due to the fact that there have been many mobile phone bursting accidents due to charging before, many people are extremely distrustful of fast charging, but in fact, there is no need to worry about it at all. At present, the fast charging technology of various mobile phone manufacturers is still very mature and has a certain technical guarantee. Because the mobile phone has set the highest protection mechanism for the battery to withstand voltage, current, temperature, etc., when setting up the fast charging function, the current fast charging technology is relatively safe.

But whether it is fast charging or slow charging, as long as it is charging, it will definitely cause permanent irreversible damage to the mobile phone, because when charging, the rapid flow of current will increase the temperature of the battery, resulting in the permanent destruction of the battery cells, but fast charging will be a little more harmful than slow charging, even if fast charging has some protection mechanisms, but the impact of fast charging on the mobile phone still exists, although fast charging can greatly improve the speed of mobile phone charging, it will also have a certain impact on the life of the battery.

The fast charging technology itself has a certain degree of loss on the battery.

However, it is very low, and the loss caused by regular products can be basically ignored, and the aging caused by normal use is not much different.

Whether or not to use fast charging itself depends on the charging head, not the charging cable, so whether or not to use the charging cable of the fast charging standard has no effect on the battery.

That TV has a fast charging function,Now the battery can basically be quickly charged with a charger,People always ask if it's right to do damage to the battery,I can only do this to you。

The number of charging times of the battery is limited, and some notify the battery to charge 10,000 words, who has reported it in this store? Some TVs may charge less. Electronics have a lifespan, and so do batteries.

When the battery is charged to its life, it will naturally end, at this time you either replace a battery and install it, or replace the product. Superfast charging has certainly been damaging lately, as it takes advantage of some of the features that mean charging has become faster.

Hot-swappable power supplies definitely don't have any effect on the screen, and I also hot-swap power supplies a lot, and it doesn't have any effect because we need to experiment.

Like your own computer, you usually take care of it, and there will be no problems.

However, it is also as little as possible, because the impact of switching from power supply to battery power supply on the computer is relatively large, that is, there will be voltage mutations in an instant, especially under the system, when playing games or doing something, it is more obvious, so try not to do this, but it generally does not matter, because the computer has a protection circuit in the power supply, which can withstand a large reverse voltage drop, so you can rest assured when you use it normally.

1. Although major OEMs have battery management systems to control the damage to batteries caused by fast charging, this is only a means and cannot be fundamentally solved. 2. In addition, the current charging pile is not unified, and it is unknown whether there is a special program for matching battery materials and temperature. 3. Combining the above factors, although fast charging does save the charging time of the car.

As follows:

Fast charging is harmful to the battery. If it refers to the fast charge itself, then it does harm to the battery, but this damage is negligible, and the benefits obtained are far greater than the damage itself. If it means that 20W exceeds 18W will not cause additional damage to the battery, as long as you use a regular charger, there is no problem, the charger will dynamically adjust the power according to the situation of the battery, and will not charge at 20W power throughout the process.

Apple's mobile phone with 20w fast charging is actually not very harmful to the battery, it can be said that it is minimal, therefore, you don't have to worry too much about the impact of using the 20w charging head on the mobile phone, it is more common now, and the apple battery itself is very power-hungry, and the battery is generally not durable when the mobile phone is long.

Does fast charging of cars hurt the battery?

In addition to this, the hazards of fast charging for lithium-ion batteries in automobiles include the cost of abandoning the life of the rechargeable battery's recirculating system.

Because the rechargeable battery is actually a device that uses electrochemical corrosion to cause electricity, the battery charging is to produce reverse chemical changes, and at the same time, for the battery, a relatively large amount of current will be typed into the rechargeable battery in an instant, and the frequent application of fast charging will reduce the recovery ability of the rechargeable battery and reduce the frequency of the discharge cycle system of the battery.

Renren rented a machine and said: Some time ago, Samsung S21 was released, with a charging power of 25W, and the iPhone 12 that we know

The charging power is 20W.

And the corresponding domestic mobile phone.

The charging power has gone to 120W, and it is even increasing.

120hz mobile phone manufacturers are happy to claim how many minutes it takes to fully charge the battery, but they never mention whether there is acceleration damage to the battery.

Then the problem comes, fast charging does not hurt the battery ridge to make a shed, I believe this problem has been bothering many users.

Does fast charging hurt the battery.

In fact, this problem is not complicated, because as long as it is charged and discharged, it will cause irreversible damage to the battery, but the degree of damage is not large.

Most fast charging technologies are nothing more than increasing the "high current or high voltage" to achieve super fast charging, so it is inevitable that high temperature, high voltage and other behaviors that are easy to damage the battery. The fast charging protocols of various brands are more to communicate with the charging components and limit the voltage and current, and regulate them according to the temperature to protect the battery.

Fast charging. Perhaps many people have experienced that the temperature of the mobile phone rises significantly during fast charging. Therefore, now the answer to the question is relatively clear, in fact, whether it is fast charging or slow charging, there is a reasonable battery life damage.

However, if the high voltage or high current used in fast charging causes high temperature problems, it will undoubtedly become the key to accelerate the battery damage battery life.

Charge. Knowing the root of the problem is the key to solving the problem. So if your phone supports super fast charging, what can you do to better protect your phone's battery?

In fact, the solution is very simple, which is to avoid the problem of overheating the battery caused by super fast charging as much as possible.

The culprit.

2. Do not use the battery until 0% and then charge it after shutting down, which will reduce the battery life.

3. Don't easily use unmatched chargers, although some chargers can still be used on your mobile phone, but there may be a lack of supporting system control, which is easy to cause overvoltage or overcurrent, abnormal temperature and damage to the battery.

Only with the right charging habits can you experience fast charging safely and effectively, and enjoy the charm of true fast charging.

If you find it helpful, pay attention to the official Zhihu of Renren Rental.

Let's talk about the latest machines and learn the most practical tips

Super fast charging doesn't cause damage to your phone.

The lifespan of a mobile phone battery is generally 300-500 charging cycles. Assuming that the power provided by a complete discharge is 1q, if the reduction of power after each charging cycle is not considered, the lithium battery can be supplied or supplemented with a total of 300q-500q of power during its lifetime. If you charge it with 1 2 each time, you can charge it 600-1000 times; If you charge it every time you use 1 3, you can charge it 900-1500 times.

And so on, if it is charged randomly, the number of times is indefinite.

In short, no matter how it is charged, the total amount of electricity added by Oak Shenhong is 300q-500q, which is constant. Therefore, filial piety can be understood in this way: the battery life of the mobile phone is related to the total charging capacity of the battery, and has nothing to do with the number of charges.

There is little difference between deep and shallow charging and shallow charging on the battery life of mobile phones.

The principle of super-fast charging technology

There are many solutions for super fast charging technology, such as Apple's PD protocol, Qualcomm Quick Charge protocol, etc., from the charger output standard to the control IC and even the power cord, there are corresponding standards, through "tailor-made" to maximize the efficiency of the mobile phone battery. Most fast charging protocols are essentially high-current or high-voltage.

However, most fast charging technologies are nothing more than "high current or high voltage" to achieve super fast charging, and various protocols are more to communicate with charging components and limit voltage and current, and regulate them according to temperature, so as to protect the battery.

Take Huawei Mate40 as an example, its operating system is EMUI11, and frequent charging with super fast charging is partially harmful to the phone. When the mobile phone is charged in Luhe, the rapid flow of current will increase the temperature of the battery, thereby destroying the electrolytic substances of the battery, causing the battery capacity to slowly change and decrease. Frequent charging will also damage the battery, and after a long time, you will find that the battery standby is delayed, the shorter the grip, and the service life of the battery will become shorter.

Whether it is fast charging or slow charging, as long as it is charged, it will definitely cause permanent irreversible damage to the battery of the mobile phone. In order to realize the fast charging function on the mobile phone, three elements need to be met, and all three are indispensable. Chargers, batteries, chargeics.

The charger needs to meet the output current and output voltage of the Azahaya State School, because the trace of the charger has a large parasitic resistance, and if you want to achieve a large charging current, the on-load output voltage of the charger needs to be higher.

I'm a fat scholar from the big fool and the second family, and I've personally experienced such a problem, **There is a detailed explanation of the situation, thank you**. First of all, because the charging voltage and current of fast charging are larger than those of slow charging, so to the extent of hurting the battery, it must be that fast charging hurts more electricity and defeats Tongchi. However, in actual use, this kind of damage is actually negligible, so there is actually no big difference between the two.

Everyone may be deceived by the gimmick of fast charging, thinking that this fast charging means ultra-high current and ultra-high voltage. However, in fact, this is a kind of voltage or current improvement within the safety range of the mobile phone. This means that this series of improvements is within the normal acceptable range of Hetan.

Considering it according to the national standard theory, I also admitted that slow charging is definitely less harmful to the battery than fast charging. After all, the current and voltage are small, and the impact on the battery will be relatively small. However, according to the current national standard theory of mobile phone batteries, as long as today's mobile phone batteries are charged and discharged 800 times, the mobile phone battery can ensure 80% of the performance is qualified.

This means that today's mobile phone batteries have to meet the standard of maintaining 80% performance for two and a half years, even if they have to be charged every day.

Fast charging doesn't hurt the battery, but frequent fast charging does hurt the battery compared to slow charging.

Dangers of Frequent Fast Charging:

1. Accelerate the polarization of battery cells.

Generally, during the charging process of lithium-ion batteries, the Li+ migration rate of the internal diffusion of the electrode is smaller than that of the electrolyte, and the internal diffusion of the electrode is the control step of the Li+ diffusion rate.

Since the migration rate of Li+ inside the electrode particles is much smaller than the electrochemical reaction rate on its surface, it causes the concentration polarization of the electrode, which will further aggravate the potential difference between the positive and negative electrodes and deviate from the equilibrium potential.

When the continuous charging current is large, the ion concentration at the electrode increases, the polarization intensifies, and the battery terminal voltage cannot directly and linearly proportional to the charged energy.

At the same time, the increase of internal resistance will lead to the Joule heating effect, which will aggravate the side reactions. For example, a series of problems such as reaction decomposition and gas production of electrolyte will increase the risk factor suddenly, which will affect the safety of the battery, and the life of non-power batteries will inevitably be greatly shortened. Hidden filial piety.

2. It may lead to cell crystallization.

During charging, our control over the lithium ions is actually very weak. We can only guarantee that lithium ions will migrate to the surface of the anode, but we cannot guarantee that the lithium ions will be evenly distributed on the surface of the anode.

In the lithium stove, the fast charging of the battery means that the lithium ions quickly come out and "swim" to the anode, which requires the anode material to have a fast lithium intercalation ability.

The anode materials used for fast charging of lithium batteries include carbon materials, lithium titanate and some other new materials. For carbon materials, because the potential of lithium intercalation is similar to that of lithium precipitation, lithium ions are generally preferentially embedded in graphite under conventional charging, but under fast charging or low temperature conditions, lithium ions may precipitate on the surface to form dendrites (also known as crystallization).

Dendrite lithium can puncture the separator (SEI), causing Li+ secondary loss and reducing battery capacity. When the lithium crystal reaches a certain amount, it will grow from the negative electrode to the separator, causing the danger of a short circuit in the battery. <>
