How to repair the loss of electric vehicle battery, and how to repair the electric vehicle battery a

Problem 1: The method of repairing the battery of an electric vehicle is as follows:

1) First of all, the "Water Loss – Remediation Method" is specifically detailed here:

Pry open the cover plate above the battery, open the rubber cap, expose the exhaust hole, through the exhaust hole can see the inside of the battery, to see if there is dryness inside the hole, that is, whether the battery has lost water. The plates of the battery are wrapped in white fiberglass wool, which should be moist under normal conditions.

Aspirate distilled water with a dropper.

The battery is injected through the exhaust hole. Cover the vent with a breathable shield to prevent dust from falling into the vent. It is best to use medical secondary distilled water. The principle of hydration is to do less than more. Not enough can be added again, more causes the specific gravity of acid to decrease, battery capacity.

will be insufficient. Easy to use and easy to measure. Hydration tools should not use any metal-containing utensils, and syringes should be used after removing the metal needle and putting a plastic tube over it.

2) Unbalance repair method: find out the capacity, voltage, self-discharge, and internal resistance of the battery.

and so on with the same battery.

3) Sulfation - repair method: the vulcanized battery is repaired with Kedi repair instrument, using fuzzy digital control theory, by measuring the state of the battery, while charging and discharging, it continuously emits positive and negative frequency conversion particle waves, and uses 10 to 20 hours to remove the hard lead sulfate that becomes hard after crystallization in the battery.

4) Plate softening - repair method: After discharging the battery, use a bulb to deeply discharge for 1-5 hours. Then use the activation instrument, activation repair.

5) Short circuit - repair method: water battery, you can punch the hole clearly, and get the lead powder out of the short circuit! Electric vehicle batteries.

It can quickly short-circuit the positive and negative electrodes, and burn off the short-circuited place!

6) Open circuit. - Repair method: 100A detects that the battery voltage 0V is an open circuit, and uses a single measurement method to use a multimeter.

Measure the place where the open circuit is opened and weld well.

Question 2: The battery contains dangerous corrosive sulfuric acid, and it is recommended that people who do not understand it at all do not try it.

Problem 3: When adding the repair solution, the tools are generally injected with a syringe (to remove the needle of the syringe) with a plastic tube or a non-metallic instrument such as a plastic funnel.

Problem 4: The shape of the battery is bulging, give up repair, and be scrapped.

The first thing to do in the repair of the electric vehicle battery is to test the battery, see how the existing capacity of the battery is, and what are the problems? For example, whether there is a single backwardness, the aging degree of the plate, etc., and then you can add pure water (distilled water or purified water), or add a special battery replenishment solution, but when adding, it depends on the specific situation, and then decide how much to add (according to the detection situation, if the battery is used for a long time and the loss of battery water is more serious, then add more appropriately, generally adding 10-30 ml)? After adding, it is best to stand for about 1 hour, so that the supplemented water fully penetrates into the plate of the battery, and then use a professional pulse repair machine to charge and repair for 10-12 hours.

I successfully solved the power deficit of my electric car battery and shared this method with you.

Repair of electric vehicle battery after power loss:1. If there is a shortage of battery fluid, you can add battery replenishment to repair it;

2. Use the full charge and full discharge method to repair, the method is: the battery is fully charged, and then discharged, this repair method causes less damage to the battery, and can also activate the active material in the deep layer of the battery, improve the capacity of the battery, and extend the battery cycle.

3. Go to the repair shop to find a professional to repair it.

Introduction:

The best way to eliminate vulcanization of the battery is to use the pulse repair method, when repairing in this way, the instantaneous voltage taken is between 60V and 300V, it should be noted that in the process of repair, the voltage used can not be too large, if the pulse voltage value is too large, it will cause damage to the battery plate and affect the service life of the battery. If the impulse voltage is high, the repair time will be shorter, and if the impulse voltage is too low, the repair time will be longer.

Power loss is insufficient power, and the intuitive manifestation is that the voltage is insufficient, which is lower than the normal value. The state of power loss does not necessarily mean that there is no electricity at all, but that there is only a small amount of power. After the power loss, because the voltage is too low, it is not enough to ignite the engine and drive the on-board electrical appliances to work normally.

If there is no power at all, the battery will be scrapped and cannot be recovered. Therefore, if you don't use the car for a long time (more than half a month), you should pay attention to charging it first.

After the electric vehicle battery loses power, it is necessary to use a charger with a larger current to recover, that is, to activate the battery that has suffered a serious loss of power through a large current, and the specific operation steps are as follows:

1. Choose a charger with the same voltage and larger current.

2. Find the charging port of the vehicle.

3. Plug in the charger.

4. Plug in the charger.

5. When the red light is on, it is charged normally.

Precautions for operation:

1. Do not activate the charge for more than 1 hour.

2. To restore the original charger charging, the power should be cut off for 1 hour after 3 hours of charging, and then recharged.

Hello friend First of all, you can add distilled water to replenish it, and you can also use a fast charger to activate it. The fast charger can be charged 24V-72V, then the battery may be recharged and the voltage will rise. Try charging for 10 minutes first, and then use the charger to continue charging slowly

Not all batteries can be repaired, and they can be refurbished if necessary.

Fixes: 1. Rematch. After the whole group of batteries is damaged, we often carry out charge and discharge tests on the batteries, and often find 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.

2. Hydration. A replenishment of water for batteries that have been used for half a year can extend the service 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 overcharged state to change the battery from a "quasi-lean liquid" to a "lean liquid" state, and this overcharging is beneficial to improve the battery capacity.

3. Eliminate vulcanization. The "Keti" battery repair equipment is used to eliminate vulcanization of the battery.

4. The particle generator is connected in parallel to the battery to repair the battery. 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, it is often completely eliminated the possibility of battery vulcanization.

5. Comprehensive repair methods.

Regular inspection of the battery, timely desulfurization and water replenishment, single battery charging, reconfiguration.

First of all, use a multimeter to measure the voltage, and the basic voltage of several groups of batteries is about the same! The group that is too different must be broken and needs to be replaced! No need to change the battery water! **Some are not expensive, and there are also needle tubes and glue! Easy to add!

The electric car battery is out of power, and the maintenance master will teach you how to remedy it, have you learned?

There is an effect. The "water loss" of the battery can be repaired by replenishing water, and the purpose is to dilute the sulfuric acid with increased concentration and carry out the electrolytic reaction normally. The method of replenishing water is relatively simple, just open the upper cover of the battery, you can see that there are six round holes, inject a certain amount of distilled water into each round hole, and then soak for more than 24 hours.

Replenishment can only replenish distilled water, and cannot add water of other components, including purified water, because there are various metal molecules in the water of other components, which are easy to cause self-discharge and damage the battery after being added to the battery.

The battery repair fluid does have a certain effect, but the effect is not good after repair, and it can only be used for a longer period of time.

Introduction:

The repair effect of the closed valve-regulated lead-acid battery within 3 years is very good, because the lead-acid battery will lose water after 1-2 years of use due to charging, and the over-discharge will cause the crystallization of lead sulfate layer by layer, and it is easier to produce sulfation after water loss, resulting in a decrease in capacity.

Battery repair solution, nothing effective. Some batteries are disadvantage after a long period of use. In fact, a little distilled water is fine. The battery can recover some capacity.

Summary. The reasons why the electric vehicle battery deteriorates after adding repair fluid may be because: 1

The repair fluid is of poor quality and has added low-quality chemicals that can cause fouling or other adverse reactions inside the battery, which can reduce the performance of the battery. 2.The added repair fluid is not suitable for your EV battery, and different types and specifications of batteries may require different types of repair fluid.

3.You are not using the repair fluid properly, for example, adding too much liquid or mixing it in a different brand or type of liquid, which can cause problems with the battery. 4.

Problems with the charger can also cause the battery to deteriorate. A fast charger can provide a higher voltage, but if the charger is set up incorrectly or malfunctioning, it can damage the battery. It is recommended to go to a professional repair shop to check the status of the battery.

The electric vehicle battery has become worse after adding the repair fluid, and it will be full after charging for a while, and it is not durable at all, what should I do?

The reasons why the electric vehicle battery deteriorates after adding repair fluid may be because: 1The repair fluid is of poor quality and contains low-quality chemicals that can lead to fouling or other adverse reactions inside the battery, which can reduce the performance of the battery.

2.The added repair fluid is not suitable for your EV battery, and different types and specifications of batteries may require different types of repair fluid. 3.

You don't use the repair fluid properly, for example, over-adding the liquid or mixing it in a different brand or type of liquid, which can cause problems with the battery. 4.Problems with the charger can also cause the battery to deteriorate.

A fast charger can provide a higher voltage hood liquid buoy, but if the charger is set up incorrectly or malfunctioning, it can damage the battery. It is recommended to go to a professional repair shop to check the status of the battery.

1.Remove the battery from the electric vehicle. 2.

Clean battery terminals and internal connectors to ensure they are clean and corrosion-free. 3.Open the battery with an appropriate hail shelter tool and inspect the interior for any significant damage or corrosion.

4.If there is significant corrosion on the surface of the battery, use sandpaper to gently grind away the corrosion. 5.

Fully charge the battery and test it with an electric vehicle to see if it lasts. If the above steps don't resolve the issue, you may want to consider replacing the battery with a new one. <>

The battery loss of electric vehicle can be repaired with battery replenishment solution.

Electric vehicle battery loss can be repaired with battery replenishment liquid, the use of a bottle can probably restore the battery, in the usual use of the car in the process of paying attention to the protection of the battery, to avoid excessive use. The battery of the electric vehicle has a certain service life, and after the service life is up, the working efficiency of the battery will decrease, and the battery will store less and less electricity.

In the process of normal use of electric vehicles, if they are used every day, it is best to charge them once a day, the charging time of electric vehicles should be basically controlled within 10 hours, and the charging time should not be too long, if the charging time is too long, it will affect the normal use of the battery, and each charge should be charged before the battery is used up, so that the damage to the battery is small, and the battery life cycle can be prolonged.

If the battery of the tram is lost and cannot be charged, you can try to activate the battery first, or replace the battery directly.

If the battery of the battery car is out of power and cannot be charged, you can try to activate the battery first. If you can't activate it yourself, you must find a professional battery maintenance personnel to activate it at this time. Do not make repairs at will yourself to avoid greater losses.

Secondly, the battery can also be activated by charging it with a fast charger.

Under normal circumstances, the fast charger can fully charge the battery within 2 hours, and check the voltage of the battery after charging, if the voltage is relatively high, it means that the battery can be used normally. The other most straightforward way is to replace the battery directly. Even if the battery has been activated, it will not last too long because it has been in a state of power loss for a certain period of time.

It is safer to replace the battery with a new one.

The cause of the power loss

There are many reasons why the battery of the battery car cannot be charged, the battery ages over time, resulting in the battery not being charged, or it may be due to the fact that the driver of the electric car often charges the electric vehicle under the scorching sun, because the weather temperature is high, and the temperature of the battery is also high when charging. In addition, due to the hot weather, the battery will be filled, which will not only lead to the battery capacity.

loss, which may also directly damage the battery, may even trigger**.

Battery car batteries are consumables.

When a battery is unusable or has reached the end of its useful life, it should be replaced. It is best to use lithium batteries for electric vehicles, although the highest is high, but the safety performance is good and the service life is long. The battery will have its own protection system every time it is charged, which is not possible with a normal battery.
