How to divide electric vehicle batteries into wet batteries and dry batteries

Dry batteries are expensive, and liquid batteries usually need to check the battery water.

That's it, if the liquid battery is used well, that is, usually check the battery water, do not let the battery water dry, the use time will generally be longer than the dry type, because the dry battery does not mean that there is no battery water, but the battery water is used less, and there is no need to add it in use!

If you have money, you can consider buying a dry type, but you don't have to think about it before the liquid from the original car is not used! (If you don't want it, give it to me!) Haha) usually check it, (the manual generally has a written check time) on the line.

My LF100-5 liquid battery is not a famous brand, but I checked it in the months after I bought it, and now the battery water will not be less, and I have used it for more than a year.

At present, there are two main types of batteries used in automobiles, one is the lead-acid battery with electrolyte.

wet), one is a maintenance-free battery (dry). Car batteries.

The length of service life not only depends on the structure and quality of the battery, but also is closely related to the operation and maintenance. Generally, the service life of automobile batteries is about 2 years, and if properly maintained, it can reach 3 to 4 years. It is very necessary to maintain the battery once during the change of seasons.

Maintenance-free batteries (dry) do not need to add distilled water.

And adjust the concentration of the electrolyte, it is fully sealed, and generally there will be no electrolyte overflow to the surface of the battery. Its maintenance is very simple, mainly to check whether there is any leakage, clean the surface dirt, treat the oxide of the positive and negative pole piles, fasten the clips of the two pole piles and observe the color of the battery eye. The color of the electric eye is green, which means that the battery is sufficient; Black is insufficient power and needs to be recharged; Gray or light yellow means that the electrolyte is insufficient, because the maintenance-free battery cannot be filled, the battery should be replaced immediately.

In addition to the maintenance items of the maintenance-free battery mentioned above, it is also necessary to pay attention to the following two aspects: one is to check and adjust the height and concentration of the electrolyte, the height of the electrolyte should be between the highest (max) and the smallest (min), too low will reduce the capacity of the battery, so that the plate produces vulcanization, too high will overflow to the surface of the battery to corrode the pole pile, wire and body. The concentration of electrolyte has a great impact on the working condition of the battery, the sulfuric acid concentration of the electrolyte in our Northeast winter should be adjusted to grams, and the concentration measurement and adjustment must be carried out under the condition that the battery is fully charged; The second is to clean and dredge the exhaust pipe, keep the exhaust pipe well ventilated, and discharge the exhaust gas generated during the charging process in time, otherwise it will lead to the overflow of the electrolyte from the liquid filling hole, and even lead to the battery in serious cases.

If you add water, you will be wet, and if you don't add water, you will be dry.

The little bird electric vehicle uses a lead-acid battery, which is composed of electrolyte, grid, plate, AGM separator, etc., and the battery manufacturer of the little bird electric vehicle is Tianneng battery.

Lead-acid batteries.

Summary. Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I'm helping you sort out the answer to your question, please wait a while The appearance of the repentance is different: the appearance of the water bottle can be seen to have liquid inside; The dry battery is a maintenance-free battery, and the battery shell is opaque in appearance, and the liquid cannot be seen on the outside, and there is no liquid filling hole on it. 2. Different volume and weight

The front of the hydropower cylinder body is large, the weight is heavier, and the capacity is large; The core panicle dry battery is small in size, light in weight, and small in capacity

Today's electric cars are all dry batteries, and I haven't seen any ordinary batteries.

In fact, the batteries sold on the market now are dry-charge batteries, and the dry-charge batteries have one more process in manufacturing than ordinary batteries, that is, a formation process is added after the completion of the plate process.

And the general people think that the battery has dry and wet, so it is wrong, the general people think that the dry battery is actually 1Closed maintenance-free, or liquid electrolyte, 2There is no liquid electrolyte, but a solid battery.

The wet battery that most people think can add electrolyte, not sealed, in fact, such batteries also have maintenance-free batteries.

It is done well, there is no need to add electrolyte, and the electricity stored is relatively more.

Most electric vehicles use dry batteries, which do not require maintenance, and the battery life is OK, and some high-power electric tricycles use wet batteries.

Of course, it is a dry battery, such a fuel cell is a cutting-edge technology, and only a few manufacturers in the world can produce dry batteries for power supply. Generally, electric vehicles are used in valve-regulated semi-sealed lead-acid batteries, although water is not visible, but it must be wet batteries, mainly because there is no special maintenance, and the disadvantage is that improper use affects the life. High-power electric drag is generally used in traditional lead-acid batteries, which have the advantages of large capacity and large discharge current, and the disadvantage is that the maintenance is large.

Does a dry battery refer to a maintenance-free lead-acid battery? Most electric vehicles use this type of battery. Although wet-cell batteries require regular maintenance, they are relatively more durable than maintenance-free lead-acid batteries.

Of course, if the LZ budget is enough, it is better to choose a lithium battery, which has a longer cycle life than a lead-acid battery, and has a large output power, smaller weight and volume, but it is also more expensive.

Dry batteries usually refer to maintenance-free batteries.

Correspondingly, the dry battery (maintenance-free type) is easier to use and tightly sealed.

The valve-controlled semi-sealed lead-acid battery for dry battery (maintenance-free type), although there is no water visible, it is definitely a wet battery, mainly because it does not need special maintenance, the sealing is tight, the internal acid is not easy to evaporate and lose, and the acid in the battery will not leak out.

Generally, the high-power electric drag type generally adopts the ordinary water-added lead-acid battery, which has the advantages of large capacity and large discharge current. The disadvantage is that it is easy to soak through the acid that leaks out of the inside of the battery, and the acid loss is large, and the maintenance is large.

Under normal use, the dry battery equipped with the rear is good.

1. The wet battery needs to be maintained, which is its biggest defect, due to the need for ventilation, the vent hole will also lead to the overflow of sulfuric acid, causing danger, the advantage of the wet battery is that it is cheap, and its advantages of large discharge current of the same battery can not be fully performed in the car. Correct and good maintenance can last slightly longer than a dry battery (however, there are usually problems such as untimely maintenance, which affects the life).

2. Dry batteries are just the opposite.

Now the market is basically maintenance-free (dry) batteries, the original batteries on the new car are basically maintenance-free (dry), maintenance-free batteries are also called dry batteries. In the past, the batteries used were liquid batteries (water type), and the battery water was actually the use of sulfuric acid, which had a strong corrosive effect on the body and clothes after the leakage of sulfuric acid and gas, and it was very troublesome to rehydrate and regularly recharge, so now the market likes to use liquid-free (dry) batteries.

The maintenance-free squint battery is a dry battery.

The electrolyte needs to be filled with a wet battery.

Electric bicycles, dry batteries for electric motorcycles, electric three-wheeled batteries, and Kaijian wet batteries.

I'm an electric vehicle engineer at Epson.

Electric vehicle batteries include: lead-acid maintenance-free batteries, gel maintenance-free batteries and batteries.

The electric vehicle battery has never been teased that there is a dry battery, although it is maintenance-free, but it is wet, like a flashlight with the dry battery!

An important feature of this finger crack of a dry battery is whether it can be recycled and whether there is a liquid as a medium!
