What water should electric car battery add?

Car battery due to serious water loss will cause serious battery vulcanization without electricity. If the battery is severely vulcanized or dehydrated, and the appearance is not damaged, bulging, no short circuit, open circuit signs, you can try to add water to the battery to repair:

Add water to repair, add deionized water or pure water to add water, do not add tap water, it will cause the problem of large self-discharge of the battery. The specific method is as follows:

1) First discharge the battery completely, because the internal acid density of the battery after discharge is basically 1.1g/mL or less;

2) Take out the cover sheet and clean it for later use;

3) Add water, generally 1g/Ah;

4) After standing for about one hour, install the safety valve and the cover sheet;

5) Charge, fully charge after full charge, and cycle three times.

It is very professional to add water to repair the battery. It is necessary to master the internal structure of the battery and the principle of the battery. Not all batteries are worthy of water repair, no voltage, no current, there is no need to repair.

If your battery is a maintenance-free battery, you can't add water. If there are six water holes on the battery, you can add water and water.

If you add water to the battery, you can add water. But not all water can be added, you can only add distilled water or battery replenishment, do not add pure water, add pure water will shorten the battery life.

If your car is a car, it is recommended that you install a maintenance-free one, so that you can save your effort and use the battery.

1, according to the length of the battery to add, more than one year plus "distilled water", the reason is that the battery is used for a long time, the acid concentration is too high, need to add distilled water to dilute.

2, the battery is less than 8 to 10 months a year plus standard battery liquid. (It is necessary to select the battery liquid of appropriate specific gravity according to the temperature of the area).

3. Do not add too much distilled water or battery liquid. Add 10 ml to each small hole of 10 to 12 AH. Add 17 ml per well to the 17 to 20 AH battery.

Precautions:

Adding more battery fluid will affect the mileage of the battery's contacts, prematurely damaging the battery.

According to the length of the battery, add more than one year of "distilled water", because the battery is used for a long time, the acid concentration is too high, you need to add distilled water to dilute! The battery is less than 8 to 10 months a year plus standard battery fluid. {Need to choose the appropriate proportion of battery liquid according to the temperature of the area! } Do not add too much distilled water or battery liquid. Add 10 ml to each small hole of 10 to 12 AH. Add 17 ml of each hole in the 17 to 20AH battery! The battery liquid is added more. Will affect the mileage of the corrosion of the battery contacts, premature damage to the battery!

The battery of the battery is a sealed maintenance-free battery. When the battery needs to be filled, the corresponding cover and rubber cap can be opened. The cover is easy to open with pull-out type, and some are glued with glue. Knock it on. In the case of hydrating the battery of the battery, the liquid of the corresponding density or distilled water is added depending on the density of the electrolyte of the battery itself. Because the electric vehicle battery is a poor liquid battery, the electrolyte is not visible inside, and the electrolyte is adsorbed into the separator. It is difficult to completely replace the electrolyte. The main reason is that the electrolyte needs to be replaced. The purity of the electrolyte used in the lean battery is very high, which is higher than the purity of the outside or the self-purchasing. The electric vehicle electrolyte is generally a dilute sulfuric acid capacity with a specific gravity of 1.30 to 1.34. If you want to match it yourself, you can measure the specific gravity while diluting the sulfuric acid. After the addition, the full-scale specific gravity is generally around 1.37. Is it feasible to repair the battery according to the battery itself? And set.

If the battery is not sure whether it is liquid or vulcanized, it is best not to add it by yourself. If the battery is short of half the capacity, it can be added slightly. (Remember that the amount of addition is very small). The tram seal valve is maintenance-free. Under normal circumstances, it is not necessary to add liquid. The scrapping of the battery is mostly caused by serious vulcanization. If the battery is added during vulcanization, it can only accelerate the vulcanization of the battery. After adding the liquid, a substance like white alkali (this is a sulfide) will emerge from the ear. Therefore, not only shortening the battery life will increase the corrosion of the ear, but also accelerate the vulcanization of the inner plate. The battery was completely scrapped. The raw materials added to the repaired batteries are mostly combined with a pulse repair machine and a desulfurization activator synthesized from various chemical raw materials. The addition of such a repairing agent without a repairing machine may also cause the internal resistance of the battery to be excessively decomposed and the desulfurization effect may not be achieved, and the self-discharging capacity of the battery may be lowered. Your battery can't be repaired if it is added with liquid. Even if it is repaired, it can't completely remove the sulfide. The capacity will be greatly reduced, and the repair effect will not be achieved. It can be used for 1 year after repairing to a professional repair shop without adding nights. If you add liquid, you can only use it for 1-2 months. The battery is scrapped as long as it is added to the liquid, even if you add liquid, it has no great effect. (Because 90% of the cause of the decline in battery capacity is not due to the loss of liquid, but because the active material falls off, the plate is severely vulcanized, and the internal resistance is too large,)

Hello friends, the battery that used to add water is a general lead-acid battery; the electrolyte inside is dilute sulfuric acid, the concentration is very high, it will corrode clothes; now the surface you see is black is actually a lead-acid battery, but it is Maintenance-free lead-acid battery, maintenance-free, you do not need to add water often, try to reduce maintenance, does not mean that there is no sulfuric acid inside it; it is recommended to use maintenance-free battery, maintenance-free battery is better, the price is higher, also save The trouble of adding water; the time of use will be longer;

The batteries used in the past are generally not sealed lead-acid batteries. Since the water in the electrolyte will volatilize, it is necessary to add water regularly. This type of battery is now rarely used. The sealed maintenance-free lead-acid battery is now used. Since it is sealed, no water is needed.

First of all, before adding water, you need to prepare the following tools, flashlight: lighting can help to clearly see the water level in the battery water hole when adding water, tweezers: absorbent paper cotton for gripping rubber cap, disposable syringe: use To add water to the battery of the electric car, with the scale on it, so that you can clearly know how much water is added. The straw: used to suck out the excess electrolyte, from the beginning: to open the battery cover, the hammer: the same function.

Prepare: Ionized water - rainwater in the rainy day with a clean container,

The plastic outer shell that is washed after the 20mL open stopper is used up,

Repair: Remove the battery case, loosen the screw, open the top cover, open the four battery plastic cover, and then pull out the 4X6=24 round leather caps. From the hole, you can see that the battery core has dried up. Add water, use the open dew shell to absorb, 20mL per hole (specifically just to see the water surface as the standard, less can be added, more than nothing) to charge it after 4-6 hours, until the charging indicator is discolored . Install 4X6=24 round leather caps, close the four battery plastic covers, tighten the screws, and install the battery case.

Note: Although the charger is not fully insured, as long as there is something wrong with the connection with the electric car, the damage to the battery is huge, so it is almost necessary to unplug the plug. (The mileage of riding is proportional to the charging time of the charger)

Primary maintenance like this is 8-12 months, and it is meaningless after 3-4 times. It is time to change the battery.

Open the battery cover---add distilled water or replenishing liquid from the lead plate 1CM---charge for about 10 hours---extract excess water when filling----clean and dip the cover, preferably in Zhuangtou Butter on the butter to prevent clogging
