Ask for help on how to speed up EV battery damage!

The seal can't be removed, and if it is removed, people won't protect you. The simplest thing is to carry two people in the car, start at the fastest speed, brake at the fastest speed, start and brake again until the electricity is used up, rest for more than ten minutes and then ride, repeat the above operation until the battery can not start at all. Fully charge again, and ride like this again.

This will break down quickly, and you won't have to move the battery, and the store won't be able to detect any signs of man-made damage.

Put a battery in the water to drown it all, and then short circuit the positive and negative poles for a short while, go to the after-sales service and say that the battery is not good, he wants to ask what's going on, you say you can't run far, if he asks how the battery got like this, you say you don't know, no one has touched it, anyway, it's a question three I don't know.

Frequent hard braking is possible.

It can be overloaded with people or goods.

It is possible to force the drive when the battery level is insufficient or the power is lost.

It is possible to place the battery without charging it in the event of a battery loss.

It is not recommended to artificially destroy the battery.

So many people want to break the battery, it is normal for the battery capacity to drop, if you think so, then the battery factory is closed. I hope you don't make it self-defeating. Before listening to the words of the following two guys, you'd better understand the shop where you sell cars, and then do it.

That's not easy to say, put the positive and negative poles together!

Or get a few more headlights and use them hard!

Just let him play to the limit!

After a few showers, it won't work!

Hehe! Or just take one of them out and pour out some of the sulfuric acid!

Then this group of batteries will be wasted!

There are two ways: First, the electric vehicle battery is closed, and it is difficult to break the partition. Use a large voltage, current to force charging, and the battery is reversed for a period of time, so that it is okay.

Second, as long as the battery is discharged and then charged for a long time, charge for 4-5 days and then take an electric furnace wire for discharge, so that the battery will be charged after two cycles, and the electric disturbance blind pool collapses is basically useless, but in this way, the battery is equivalent to reaching the scrap period, even if the new battery is tossed like this, it will be recharged and the power is insufficient, and the battery will be consumed very quickly when installed in the car. If you want to replace the new battery, you can only say that you can charge it according to the charging instructions, but the battery problem is deformed by itself, and the power is not enough pure Li Yuan.

Electric vehicle battery simple repair can be done in one trick, the details are as follows:

1. Water replenishment: Replenish water for batteries that have been used for half a year can prolong the life of the battery, and the extension time can reach more than 3 months on average. It should be noted that after each water replenishment, the battery is in an overcharge state to change the battery from a "quasi-lean liquid" to a "lean liquid" state, and this overcharge is very beneficial to enhance the capacitance.

2. Eliminate vulcanization: choose a battery repair facility.

How to repair an electric vehicle battery.

1. Water replenishment: Replenish water for batteries that have been used for half a year can prolong the life of the battery, and the extension time can reach more than 3 months on average. It should be noted that after each replenishment, the battery is in an overcharge state to change the battery from a "quasi-lean liquid" to a "lean liquid" state, and this over-Nazen charging is very beneficial to enhance the electric capacity.

2. Eliminate vulcanization: select battery repair facilities and dissipate and remove vulcanization of the battery.

3. Reassembly: After the entire battery pack is damaged, the battery should be charged and discharged. During the inspection, it is common to find that 50% of the batteries in Group 1 are not damaged.

The reason is that in the series battery pack, a small number of cells lag behind, resulting in the function of the entire battery pack decreasing, so the function of the entire battery pack decreases.

4. Particle generator: Select the particle generator, connect it to the battery, and repair the battery. This method is more suitable for repairing batteries. However, because the repair is very thorough, the possibility of battery vulcanization is usually completely eliminated for batteries that are in continuous use if there is no over-discharge.

5. Comprehensive repair: select regular inspection of the battery, and timely desulfurization and water replenishment. Only one battery is charged, and the battery is newly assembled.

If it is maintenance-free, there is usually no need to add water. If you need to add water, first check the electrolyte density of the electric vehicle battery itself, and choose the corresponding concentration of water supplement according to different situations to increase the capacity or extend the life.

If you want to physically burn your hands and manually break it, just take out the battery and fall it, but if you want to damage it by using acceleration, you can expose the battery to the sun, causing the battery to bulge, or charge frequently, each charge is more than 10 hours, put heavy objects on the electric vehicle when riding, and ride with loads.

<>These are the practices that are more harmful to the mold battery.

The battery capacity drop can be fixed by the following three methods.

1. Water**. For vulcanized batteries, the battery can be discharged first, the original electrolyte can be poured out and injected with a dilute electrolyte with the following density, that is, water is added to the battery to dilute the electrolyte to improve the solubility of lead sulfate. The current below the 20h rate is used, and the liquid temperature does not exceed 20 40 for a long time.

2. Shallow cycle charging method. For the vulcanized battery, the current within the rate of 5h with high current is adopted, and the liquid temperature is not more than 40 degrees when the battery is charged to a slightly overcharged state, and then discharged by 30%, so that the vulcanization phenomenon can be reduced and eliminated several times.

3. Repair instrument repair. For vulcanized batteries, some special pulse repair instruments can be used to charge and discharge the battery several times to eliminate vulcanization.

1. Hydration:A rehydration of a battery that has been used for half a year can extend the service life of the battery, and the extension time can reach an average of more than three months. It should be noted that after each water replenishment, the battery is in an overcharged state to change the battery from a "quasi-lean liquid" to a "lean liquid" state, and this overcharge is good for improving the battery capacity!

2. Eliminate vulcanizationBattery repair equipment is used to eliminate vulcanization of the battery!

3. Rematching:After the whole group of batteries is damaged, we have to carry out charge and discharge testing on the batteries, and it is often found that 50% of the batteries in a group of batteries are not damaged. The reason is that in the series battery pack, the individual batteries lag behind and the function of the whole group of batteries declines, so that the function of the whole group of batteries declines!

4. Particle generator:The particle generator is used to connect the battery in parallel to repair the battery, and this method is better for repairing the battery, but because the repair is more thorough, if there is no over-discharge, for the continuous use of the battery, the possibility of battery vulcanization is often completely eliminated!

5. Comprehensive restorationAdopt regular inspection of the battery, timely sulfur removal and water replenishment. If you need to add water, first check the electrolyte density of the electric vehicle battery itself, and choose the corresponding concentration of water to supplement according to different situations, so as to increase the battery capacity or extend the service life!

Unscrew the unscrewed screws with a screwdriver and remove the battery cover.

2.Use a syringe to fill those six screw holes with water.

3.After waiting for the battery to stand still for half an hour, use a wire to connect the positive and negative terminals of the battery and a 12-volt light bulb in series to let the battery discharge.

4.Use a pulse charger to reverse the positive and negative poles of the battery to charge the battery.

5.Once fully charged, use a syringe to suck out the excess water from the six screw holes, then close the battery cover, screw the screws, and continue to use.

6. For vulcanized batteries, pour out the original electrolyte, add pure water and sodium sulfate, potassium sulfate, tartaric acid and other substances, take normal charging and discharging several times, and then pour out pure water and add slightly high-density acid to adjust the acid in the battery to the concentration of the standard solution, and the capacity can be restored to more than 80% It can be considered that the repair is successful. In this method, these sulfate coordination dopants can form coordination compounds with many metal ions, including sulfide salts. The compounds formed are unstable in acidic media, and the non-conductive sulfide layer will be gradually dissolved back into solution, so that the plate vulcanization desorption dissolves.

The characteristics of this method are higher than those of the first two repair methods, and the disadvantages are too cumbersome.

7. For vulcanization batteries, some special pulse repair instruments can be used to charge and discharge the battery several times to eliminate vulcanization. In this method, from the solid physical point of view, any insulation layer can break down at a sufficiently high voltage. Once the insulation is broken down, it changes from an insulating state to a conductive state.

If a momentary high voltage is applied to the sulfate layer with a large conductivity differential resistance, large lead sulfate crystals can be broken down. If this high voltage is short enough and the current is limited, the charging current is properly controlled in the case of penetrating the sulfide layer, and the battery gassing will not be caused. The amount of gas evolution of the battery depends on the terminal voltage of the battery and the size of the charging current, if the pulse width is short enough, the duty cycle is large enough, it can be under the condition of ensuring the breakdown of coarse lead sulfate crystals, and the micro-charging that occurs at the same time is too late to form gas evolution, if it contains negative pulse depolarization, it can better ensure that the gas precipitation of the plate is more guaranteed when the sulfate layer is broken, so that the pulse eliminates sulfidation.

The above methods play a certain role in the repair of the battery, you can try it at home.

2. There are 6 small holes inside, cover it with a rubber cap, and take it away together with the white adsorption cotton around it.

3. Use the injection syringe to add about 25 ml of replenishment solution to each small hole (depending on the lack of liquid in the personal battery, pay attention not to exceed the above plate, otherwise the liquid in the charging will be full, because the liquid will boil during charging, and it will be withdrawn if you add more).

4. Wipe off the leakage around the periphery, restore the cap, adsorb the cotton, and wrap the battery with tape.

If you have to put the battery car for more than half a year, it can not be solved by adding battery replenishment liquid, put more than a year of battery, we have to remove the battery one by one, through the 12V battery charger, charge it one by one, each battery charging time is 2 hours, after the charging is completed, we will install the battery, charge it through the charging pile, most of it can be repaired, if you have the battery 12V charger can not be charged, then you have to replace the battery.

There is no repair for battery capacity and life, and only when used correctly can the service life and time be extended.

The so-called repair, such as lead-acid batteries, only uses pulsed electrical signals to make the polarized material of the plate fall off, so as to achieve the purpose of temporary continuous use for a short time.

The end-use time is not as good as it should be. It is not possible to fix as new.

It is important to remember that the battery capacity is under the correct use to ensure that the battery lasts for a long time.

Such as lead-acid batteries. There is no such thing as fast charging, and in terms of principle and structure, fast charging is not supported. Once it is believed that the market can charge quickly, it will quickly cause the battery plates to polarize, evaporate with the electrolyte, and the battery will be scrapped.

At the same time, I am afraid of overcharging, and the market advertises that it should be fully charged at any time, which is wrong, the lead-acid battery will heat up when it is fully charged, which will cause the battery electrolyte to evaporate, so that the battery capacity will be gone after one year of use. That's why it's only a year to pay money to manufacturers and the market.

How to use it correctly: Decide whether you need to charge it based on the mileage you will be traveling. If the battery level can support the round-trip range, it is best to wait for the battery to be about the same before fully charging.

That is, reducing the number of battery recharges can increase the battery life.

Electric vehicle battery repair method, absolutely dry goods please collect.

！In fact, the repair of electric vehicles has only started in recent years, in fact, I recommend not to repair the repair after the completion of the repair is actually a lot of money, but I hope the effect is not very obvious, I suggest that it is better to replace it with a new one, it will not be very expensive.

Electric vehicle battery repair, I feel that it is better to trade in the old for the new battery directly, because the repair also needs to spend some money, but also troublesome, the repair can be renewed for a short time, spend a little more money to replace the new battery can be used for about two and a half years.

Battery repair is mainly for the old battery that has been used or is in use to complete a series of repair, repair, refurbishment and other processes, now all vehicles are inseparable from the battery, including cars, electric vehicles, motorcycles, electric vehicles three-wheeled, trucks, ships, agricultural vehicles, etc.

Battery repair is mainly for battery vulcanization, active material shedding, plate softening, hardening and a series of problems for direct repair (more than 90% of the battery is due to the above problems), such as broken poles, broken grids, plate string holes, shell leakage and other hardware damage can be repaired first and then repaired can reach a perfect value. Battery repair technology can use relatively old methods, such as acid method, high current charging method, water, activation, scanning, broadband, high frequency, resonance, pulse and other repair methods, the latest methods are: microcomputer positive and negative ion battery repair technology, composite ion repair technology, etc., are relatively perfect.

If you just want to repair your own battery, it is recommended to find a manufacturer who specializes in repairing the battery.
