How to repair lithium battery of electric car

Use electric vehicles charger to repair battery:

Electric car charger (voltage, current and electric vehicle battery type, specification is match. Therefore, car charger cannot repair the battery pack, but using a bigger size electric power charger is OK. Example: 1, the electric car battery specification is 48 v20ah. It can use 60 v20ah battery charger to repair;2, 48 v12ah battery pack can use 48 v20ah battery charger to repair.

Principle of repair: battery is the main reason for decline in performance sulfide, battery manufacturers after-sales maintenance, in the market for all kinds of battery repair, repair kits are made of high power charging equipment, using the large current, high voltage sulfide, repair the battery. So a bigger size ordinary charger to recharge the battery power has the function of sulfur in addition to repair.

Other methods:

Repair the battery with dry cleaners hot gas water

Not far from the broad masses of users are aware of electric bike journey to run, you need to add distilled water to maintenance repair battery. But is sold on the market of pure water and all kinds of supplements, repair, the action of the battery has a short and then accelerate the battery performance decline, scrap in advance. Because, these metal ions and impurities in the liquid will be corroded battery plate, cause the battery self-discharge and active substances from falling out, causing permanent battery scrap.

With electric vehicles in the requirement of increasing the performance and energy conservation, environmental protection, the lithium battery gradually replace

The lead and acid battery, but not always can use batteries, even the high performance lithium battery is not case

In use on the dynamic performance and battery life after a certain period of time can't meet demand and the only choice to replace

Waste.

But there are a lot of people will want to the lithium battery can't technically to repair? Who can and after years of exploration and research to be sure to tell everyone, lithium battery repair is completely can be done, can come out and in a professional of lithium battery repair technology for large introduce secondary lithium battery, see the electric lithium battery can be repaired?

Electric lithium battery can be repaired? Who can and lithium battery repair method:

Lead-acid battery can repair on market at present is more than I want to have a lot of friends know, but the lithium battery can repair for you temporarily haven't heard and seen, this is because the application of lithium batteries is the rapid development of only a few years, there are a lot of companies are developing design, but so far no results.

Who can and is a focus on lithium battery research and development, design, production and sales of more than 10 years of senior power enterprises, after years of research and development and technology research and development of breakthrough finally design a set of lithium batteries can be repaired more than 90% of the dynamic performance and life of equipment.

In order to, the correct use of lithium-ion batteries

Although lithium batteries, widely used in automobile, electric cars, mobile phones, tablet, notebook, and so on are useful to the equipment, in the near future, maybe have more equipment to use it, but for now, equipment, such as cell phones and tablet, is still the nearest lithium battery power supply equipment. Therefore, it is necessary to make special instructions to cell phone lithium battery.

1, the charging

That should be paid attention to in using lithium battery, battery placed after a period of time to enter a dormant state, capacity is lower than normal at this time, use time is shortened. But the lithium battery is easy to activate, if after 3-5 times the normal charge and discharge cycle can activate cells, back to normal capacity. Due to the characteristics of lithium battery itself, determines its almost no memory effect. New lithium-ion batteries in the user's phone in the process of activation, is don't need special method and the device. Is so in theory, not only from my own practice, from the start with a standard method to charge this way of "natural activation" is the best. For the "activation" of lithium-ion batteries, many say: charging time must be more than 12 hours, if you do this three times, in order to activate the battery. This "the first three time charge to charge more than 12 hours", apparently from nickel battery, such as nickel cadmium and nickel metal hydride) continue down. So that, the outset misinformation, so to speak. Lithium-ion and nickel batteries charging and discharging characteristics have very big difference, and can be very clear tell you, I have looked at all serious formal technical data will emphasize overcharge and over discharge of lithium batteries, especially in the liquid lithium ion batteries caused great damage. And charging in accordance with the best charging standard time and standard methods, especially don't charging for more than 12 hours long. Usually, the introduction of charging method, on the phone's manual standard charging method is suitable for the mobile phone.

In addition, the lithium battery cell phone or the charger will automatically stop after the battery, there is no nickel electric charger of the so-called "trickle charging for 10 hours. That is to say, if your lithium battery, after full on the charger is Bai Chong. And none of us there is no guarantee that the battery charge and discharge protection circuit will never change and quality according to the features of foolproof, so your battery will be on the brink of danger for a long time. This is another reason we object to a longer charge. Charging in addition on the phone for some, after more than a certain amount of time, if you don't go to remove the charger, the system does not stop charging, will also begin to discharge - charging cycles. Perhaps this vendor has its purpose, but apparently for life of battery and mobile phone/charger is unfavorable. At the same time, the charging takes a long time long, often need to be done in the night, and to power grid in China, many places are relatively high voltage in the night, and volatile. Have already said, in front of the lithium battery is very delicate, it is better than nickel electric resistance to fluctuation in charging and discharging ability worse, so it brings the risk of additional. In addition, another aspect can not be ignored is the lithium battery is also not suitable for discharge, over discharge to the lithium battery is bad also. This leads to the following questions.

2, when in normal use should start charging

On the BBS, can often see this statement, because the number of charge and discharge is limited, so should be mobile phone battery electric light recharging as much as possible. But find a lithium ion battery charge and discharge cycle experiment table, data of cycle life are listed as follows:

Cycle lifetime (10% DOD) : > 1000 times

Cycle lifetime (100% DOD) : > 200 times

The DOD is the abbreviation of the depth of discharge. From the table, but the depth of the number of charging and discharging, 10% DOD cycle life than 100% DOD much longer., of course, if the conversion to the actual charge relative to the total capacity: * 1000 * 200 = 200 = 100100%, 10% of the latter to fully charge and discharge is still relatively better. Under normal circumstances, you should have a reservation, according to the principle of battery remaining power run out to refill charging, but if the battery in expected to 2 days can't insist on the whole during the day, should be timely start charging, of course, if willing to carry the charger to the office when BieLun again. And need to charge for the upcoming is expected to lead to the communication of the most important events in the busy, even when there are a lot more than battery, so you can just charge in advance, because you don't have a "1" real loss time charge cycle life, namely "0. X", and often the x will be small. The principle of battery remaining power run out to refill is not want you to extremes. As widespread and long charging a saying that is "as far as possible put the cell phone battery power run out, had better use automatic shutdown". The practice of this kind of practice is just nickel batteries, and purpose is to avoid the memory effect, unfortunately it also in lithium battery of circulating on today. Once someone because the cell phone battery low warning, without a charge to continue using has been used examples of automatic shutdown. The result from this example phone no response in the later charging and boot, had to send to the maintenance of the service. This is because the battery voltage is too low, caused by the excessive discharge that do not have normal charging and boot conditions.

3, important for the proper use of lithium battery cell phone

Boil down to, I on the problem of lithium battery cell phones in use is the most important tip:

1, according to the standard time and procedure charging, even so will three times before;

2, when there is a hint when battery power is too low, should try to start charging in a timely manner;

3, the activation of the lithium battery does not need special method, in the normal use of mobile phone lithium batteries will naturally activation. If you are determined to use of "three times before 12 hours long charging activation" approach, in fact there will be no effect. Therefore, all the pursuit of 12 hours long use the lithium battery cell phone charging and automatic shutdown are wrong. If you've made according to the error, please correct in time, maybe it is not too late. Of course, in the mobile phone and charger itself under the condition of good quality, protection and control circuit for lithium battery protection still has quite a guarantee. So the understanding of charging rules is the key, in some cases, also can make some concessions. Such as found that mobile phone must be charge before you sleep at night, also can start charging before going to bed. The crux of the problem is that, should know what is the right thing to do, and do not deliberately accord to error.

Second, the battery maintenance

Actually the battery without too much consideration on the use of attention, in other words is also not too helpful. How many times a cell can use, difference between individual differences in more from the battery itself, instead of using the method. In addition to the quality of battery, the service life of the battery itself is limited. Once the battery is off the production line, its life starts to pass. Whether or not you use it, the service life of lithium-ion batteries are only in two to three years. Battery capacity decline in one of the important reasons is caused by the oxidation of internal resistance increases, and the cell resistance can reach a certain point, although a full battery at this moment, but the battery can't release already stored power. Many friends think first use lithium battery should be charged more than 16 hours, so that we can fully activate cells, actually do not according to, this is just the popular Ni-Mh or nickel cadmium battery charging method, is not suitable for lithium ion batteries. Because of this with a core of lithium polymer batteries, in theory, no memory effect, even if have, also is completely negligible. So just rushing around 3 hours is ok, if charging status has been completed, and the power converter is temporarily do not need to use, you can unplug the power and don't have to wait so long.

Myth: PSP buy requires repeated three times in order to activate the battery charging and discharging. Unless you buy the PSP is the inventory of products more than one year, otherwise there is no need to do this, because now the batteries have been activated in the factory, the batteries when encapsulated into a PSP batteries after an equivalent to activate test again, so you get its hands on the battery, already had been activated, only three times of charging and discharging process cost anymore to increase the wastage of the battery.

Erroneous zone 2: for the first time charge must be sufficient enough for 12 hours. For the those without early control circuit of Ni-Mh battery equipment is applicable, but for now has a smart charging and discharging control module of the PSP is a joke, when the PSP batteries, the charging current can be automatically cut off, and when the system is shown as "external power supply. Even if you continue to 120 hours, filling state also won't have any change, in general, is completely filled with 3 hours, the rest of the "charging" is just wasting your time. Is the time to get a new machine instead should put power rechargeable light.

Myth 3: cells need once a month completely charged. For Ni-Mh battery memory effect is very strong, this is must work, but for lithium-ion batteries, the cycle is too frequent, lithium battery, in theory, is to eliminate the memory effect, even if there were, also has been greatly weakened the negligible degree, if you use the battery is very frequent, then you should discharge the battery to the low (about 10 ~ 15%) recharging, but if the discharge to even open machine (0 ~ 1%), belong to the lithium battery has great damage depth of discharge, usually once every 2 months to do this operation. If you rarely use the battery, as long as once every 3 months take this operation.

Myth 4: charging while working, or continue to use after the completion of the power converter can damage the host and the battery. This is one of the most ridiculous arguments. So-called cavity electronics, time filling the theoretical arguments on the level of mechanism. How much you can learn in the actual reaction? Battery industry academic view is not unified at the first. Theory still has differences. How do you guide consumers to use the actual? Battery consumption is divided into normal loss and damage loss. The power converter using and the degree of loss of charge while using are completely within the normal consumption. No matter how theoretical maintenance measures system, battery is aging. It's like how the magic of cosmetics and maintenance also cannot stop the beauty become old woman. It can make aging be slower, but the surface change is not real. This is by no means theory can explain the actual use experience is correct - respect and understanding of the scientific concept. Maybe someone says, the only way to avoid the battery aging is no usage, so a lot of people will choose to take down the battery.  But it would make PSP portability loss of meaning, and secondly the battery is even in the condition of storage, and over time and natural aging. Battery is actually a half consumption product, as long as the battery has brought convenient enough for you and happiness, I think the sacrifice is valuable.
