How to solve the problem of electric vehicle battery drumming?

If the battery bulges, it is best to replace it, generally the high pressure inside the battery will deform the battery shell, such a battery is more dangerous, if the pressure inside continues to increase, the shell will crack, the battery liquid will flow out, not only will corrode the body, and even cause a fire, so the battery drum, it is best to replace it immediately.

If the charging time is too long or the quality of the battery is poor, it will cause the problem of the battery being charged, and there is no good way but to replace the battery.

The battery is deformed, and the plates inside are easy to short circuit, and the battery needs to be replaced if it cannot be repaired.

Overcharging causes the battery to swell, which affects the shedding of the active material in the battery, and should be replaced.

In life, many users have encountered the problem of battery charging, but few users know the reasons for battery charging and the solutions. In this regard, I will give you a detailed analysis today. In fact, there are generally 4 reasons for the battery charge of electric vehicles.

Fast charging for long periods of time.

This includes prolonged use of fast charging stations and fast chargers, which causes the battery to lose water faster and then inflate. For this kind of problem, avoid frequent use of fast charging, and try to use the original charger for charging, which can also reduce the probability of battery overcharge to a certain extent.

The charger is of poor quality or the components are falling off.

If the EV charger has a problem with the components falling off, then the parameters of the charger will be deviated, which will directly lead to overcharging, which will cause the battery to charge. In addition, poor quality chargers are also a big problem, and some chargers are not of good quality, which will also make the output power uneven, which can cause battery charging problems. For this kind of problem, choosing a reliable brand charger will minimize the risk of battery charging.

The charger does not match.

To put it simply, it is to take a high-power charger to charge a low-power electric vehicle battery, such as a 72V charger to charge a 60V battery, the charging voltage does not match, which will overcharge the battery and cause a situation of filling. For these two problems, the problem of battery charging can be solved by not mixing chargers and making special chargers for special vehicles.

Charge at high temperatures.

In addition, charging at high temperatures may also inflate the battery. Why? Because electric vehicles will emit a lot of heat during the charging process.

If it is still charged at high temperature at this time, the electric vehicle battery will not have time to dissipate heat, which will lead to the acceleration of the battery water loss and cause the charging situation. For this kind of problem, users should try to choose to charge in a cool place, and the charging time is best controlled within 8 hours, so as to effectively prevent the battery from charging.

In short, the charging of electric vehicle batteries is generally caused by the above four reasons. For users, they should learn to avoid the above four ways and achieve reasonable use and reasonable charging, so as to maximize the service life of electric vehicle batteries and prevent battery charging. Of course, if the EV battery has already been charged, then it needs to be replaced with a new battery in time.

If the battery car battery is bulging, it cannot be used continuously. The battery after the drum is easy to cause reverse pole in the later stage: that is, the positive pole becomes the negative pole, and the negative pole becomes the positive pole, which will cause the charger to burn out, resulting in damage to the controller, and the most serious thing is that if the controller and the charger protection function is not comprehensive enough, it will also lead to a fire, so once the drum starts, replace it as soon as possible to avoid existingSafety hazards

The battery bulges, professionally speaking, it is battery flatulence.

Battery flatulence can still be used, but the performance of the battery will be affected, and there is also a certain danger, and in the most serious cases, it can even lead to the battery **. Therefore, it is recommended that the battery flatulence should not be used, and it can be replaced directly, first of all, the safety performance of the seriously deformed battery decreases, and at the same time, the performance of the seriously deformed battery deteriorates, and the base has no value in continuing to use it at all.

Pay attention to the electric vehicle battery.

Many electric vehicles use Bocha scum households to charge when they go home from work and cut off the power when they go to work the next day, in fact, most chargers cannot 100% guarantee that the battery will automatically turn off when the battery is full. The best way is to buy a smart socket and set the time when charging, so that you can solve the problem of resting at night.

It is strictly forbidden to exercise without electricity. Recharge the electric car until it can't be ridden, which seriously damages the battery performance. Multiple deep discharges can drastically reduce battery life. If the power is not sufficient on the way, it is best to pedal the assist in advance to avoid deep discharge.

Summary. Dear, hello, the battery bulge of electric car this is not a thorough solution. First, you can add some repair solution to the battery for the battery bulge, generally about 8 to 10 ml.

Second, charge the battery after adding the repair solution, and charge it for 8 to 10 hours. Third, measure the relevant performance of the battery, if the performance of the battery measurement is still good, then this can be insisted on, pay attention to charging in the future, and don't take too long. Dear, I wish you a happy life, if you have any questions, you can continue to consult, I will answer for you as soon as possible.

If the battery of an electric car is full, the best solution is to replace it with a new one.

If the battery of the electric vehicle can no longer be charged, there is no way to rescue it, because there will be a lot of gas accumulated inside the battery.

And after the battery is charged, the pressure in it will continue to surge and there is no way to release it. If it is a lead-acid battery, some liquid that corrodes the car body will flow out, that is, some sulfuric acid. Not only will it cause deep damage, if the sulfuric acid corrodes to the electrical circuit plate, it may cause a short circuit or combustion inside the electric vehicle, so when the battery is charged, the best way is to push the electric vehicle to a special repair shop and let the master help replace it.

You can use, you open the lid in each slot and add about 10 ml of pure water, and then cover the lid, and charge it for 4 hours each time in the future, or charge it for 4 hours each time without adding water, and it can't be charged for too long.

Replace the battery after charging.

The charging time becomes shorter and the discharge time becomes shorter. Serious impact on daily life.

If it's just a drum, you can add some water, open the lid of Xiao Shisheng above, see how much Dan Dan liquid is missing, and then charge the small current to the specific gravity, which can generally be used for half a year.

OK. If the appearance of the battery is not damaged, swollen, and there are no signs of short circuit or open circuit, the following methods can be taken to try to repair the battery:

1. Use positive and negative pulses to depolarize and charge the battery, and then completely discharge, so cycle three times, if the capacity has signs of recovery, you can cycle a few more times to achieve a better repair effect.

2. Add water for repair, add deionized water or purified water when adding water, do not add tap water, it will cause the problem of large battery self-discharge.

1. Discharge the battery completely first, because the acid density inside the battery is basically below after discharge;

2. Take out the cover piece, and then remove the safety valve, pay attention to save the trapping, and do not dirty the safety valve for later use;

3. Add water, generally the water added to a single grid of 12ah battery is 8 10g, and the water added to a single grid of 20ah battery is about 15g;

4. Let stand for about an hour, and install the safety valve and cover;

5. Charge, fully charge and then fully discharge, so cycle three times, and the capacity will be better.

Lead-acid batteries should be done when not in use for a long time:

1. The battery must be fully charged before being put aside, and under the premise of full charge, it is generally recommended that the battery must be replenished in 2 and 3 months, and it is best to charge it once in 1 2 months if possible.

2. When the electric vehicle is not in use, it needs to be stored in a ventilated and cool room, and the load line is disconnected after the battery pack is fully charged, because the self-discharge of the lead-acid battery itself will cause sulfation, if it is not replenished for a long time, it will be difficult to restore the capacity to affect the life, so it is generally recommended that the battery must be replenished in 2 or 3 months to facilitate the battery life.

It is recommended not to use the battery bulge, or go to the electric vehicle professional repair shop for testing to see what causes the bulging, whether there are potential safety hazards, and replace the electric vehicle battery if necessary. There are many reasons for the phenomenon of battery bulging:

1) The ventilation hole is blocked. If the vent on the battery refill cover is blocked or blocked, the gas generated when the charging time is too long or the charging voltage is too high will gradually accumulate, resulting in increasing pressure in the battery case, and finally causing the battery to bulge.

2) Vulcanization occurs in the battery potato plate. During the charging process of high-current battery, the single-cell voltage and electrolyte temperature will rise rapidly, and the bubbles will be generated early and violently, which can easily cause the battery to bulge.

3) The tabs and poles of the inner plate of the battery are not firmly welded with the busbar. When the tabs and poles of the inner plate of the battery are not firmly welded with the busbar, if the high current is discharged, the welding will cause ignition and ablation due to the contact point is too thin or the contact is poor, which will cause sparks and ignite the hydrogen and oxygen mixed gas produced by the battery, resulting in the battery.

4) The amount of electrolyte is too small. As we all know, batteries can lead to a decrease in electrolyte after a period of use, and electrolyte or distilled water needs to be added. After the electrolyte is reduced, the battery will swell and even cause **.

Therefore, if you find that the battery is bulging, you should hurry to the professional maintenance shop of electric vehicles for testing and symptomatic treatment.

The EV battery bulge doesn't work. The battery has been bulging, which proves that the battery has started to deteriorate, and such a battery is difficult to fully charge, no matter how long it takes.

The battery after the drum is easy to cause reverse pole in the later stage: that is, the positive pole becomes the negative pole, and the negative pole becomes the positive pole, which will cause the charger to burn out, resulting in damage to the controller, and the most serious thing is that if the controller and the charger protection function is not comprehensive enough, it will also lead to fire, so once the drum is started, replace it as soon as possible to avoid potential safety hazards.

If the battery of an electric car bulges, it can no longer be used. The bulging battery not only has leakage, but is also harmful to the human body.

How to buy a battery:

1. Buy battery products with the signs of "national inspection-free" and "China famous brand" and local famous brand battery products. The quality of these products is ***.
