The correct way of using the lithium battery

The lithium battery of electric vehicle usually has at least ten groups of lithium batteries in series or more, and the battery protection board, completely different from the lead-acid battery pack (the number of small, generally no protection board), if there is a failure, non-professional technicians generally cannot solve.

The damage of lithium battery pack in electric vehicle generally includes the following situations:

1, battery protection board is damaged, the electronic density, generally difficult to maintenance;

2, battery protection board in good condition, single individual battery performance becomes poor, find it is not easy;

3, battery protection board in good condition, individual battery short circuit, to screen;

All in all, after electric lithium battery failure, maintenance difficulties, usually find after-sales, technical personnel to solve by manufacturer, or replace the same model electric lithium battery pack.

With electric vehicle battery charger repair battery:

Electric car charger charging voltage, current and electric car battery model, specifications are matched. Therefore, the car with a charger is not able to repair the battery pack, to use a larger power of the electric car charger can. Example: 1. The battery pack of electric vehicle is 48v20AH, which can be charged and repaired with 60V20AH battery charger. 2. 48v12AH battery pack, which can be charged and repaired with 60V20AH battery charger.

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.

For each hole with a syringe filled with distilled water, if add 1.28 standard electrolyte, plate may be because of the high spent acid soluble and burn out. Why, for example, we eat hot pot, the more you have, the more salty, that is to say, at the time of water evaporation, the salt is not by water vapor and evaporation, likewise, will not evaporate, battery acid is the lack of water, so we just join in each hole about 20-30 ml of distilled water.

The battery still half an hour, after full plate around the sponge absorb moisture. Then with discharge resistance, the battery, after all, there is no resistance, can replace with a 12 v bulbs, such as: motorcycle headlights, car lights can, as long as you can have the effect of discharge to 0 v. How to judge whether a battery is nearly close to no electricity, cement resistance discharge resistor body hot at the beginning, slowly gradually is not hot, when the battery is the power went out. Light bulbs, more directly, as long as see light slowly not lit, means the end of the battery discharge, the discharge time depends on the battery discharge capacity, we can put the battery first ride to maintain when no electricity, so that we can shorten the time of discharge.

After the discharge to recharge the battery, conditional can use pulse charging ways, because of the pulse charging method can effectively remove the plate vulcanizing, improve the capacity of the battery. No car can also charge to replace.

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, it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not need special methods and devices during the activation process. Not only in theory, but in my own practice, the "natural activation" of a standard charge from the start 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, a phone or charger with a lithium battery will automatically stop charging when the battery is fully charged, and there is no so-called "trickle" of charging that lasts for more than 10 hours. In other words, if your lithium battery is fully charged, it will go blank on the charger. And none of us can guarantee that the battery charge-discharge protection circuit characteristics will never change and the quality of foolproof, so your battery will be in danger for a long time to wander around. This is another reason we oppose long - term charging. In addition, on some mobile phones, if the charger is not removed after charging for a certain period of time, the system will not only not stop charging, but also start the discharging - charging cycle. There may be a purpose to this, but it is clearly detrimental to battery and phone/charger life. At the same time, long charging takes a long time and often takes place at night. In China's power grid, the voltage at night is high and fluctuates greatly in many places. Having said that lithium batteries are delicate, they are much less resistant to fluctuations in charge and discharge than nickel ones, which poses additional risks. In addition, another aspect that cannot be ignored is that lithium battery is also not suitable for over discharge, over discharge on lithium battery is also very bad. This leads to the following question.
