Main points and precautions to extend the life of automotive battery life

First, the basic structure of the battery is not difficult to see by the above figure, and our usual battery is composed of some boards. These boards are called polar plates, and their plates are divided into positive plates, positive, and negative plates are made with some active materials. Mud Similarly, the paste is in a special net (grid), the positive electrode plate and the positive plate are connected together, the negative plate and the negative plate are connected together, and then the positive and negative plates are stacked together, respectively, with a terminal lead.

In order not to let the positive, negative plate contact, in each of the positive and negative plates, it is put into the separator, which constitutes the battery core, and then placed in a special box, then incubation (sulfuric acid and pure water) The mixture), so the battery is made. Second, the active substance of the basic working principle of the battery is the active substance of the primary plate, the active substance of the negative electrode plate is a sponge-shaped pure lead, which is relatively loose. When placing them in the electrolyte, the negative plate will be With electricity, we have the power we need.

When you use the electricity (such as start, lighting, etc.), the battery will discharge, while discharging, the neutralization of the neutral plate and the sponge-shaped pure-shaped pure lead will part into the lead in sulfate, and the electrolyte consumes simultaneous consumption. A certain sulfuric acid, the more sulfuric acid consumed by the discharge, the more positive and negative electrode plates.

Lead of the cellululfate is relatively large, and the structure is relatively close. When the battery is insufficient, the battery is charged, and the charging is under the use of external electrical energy, so that the discharge after the discharge is restored to the start of the positive and negative electrode plates, and the sponge-shaped pure lead, which is consumed. Sulfuric acid is returned to the electrolyte, so charging, the discharge battery can be recycled.

Third, the battery is common, and there are many types of fault battery, and I only introduce two of our best. 1, the active material is falling off. What is the active material falling off: the so-called active material is detached, which is the positive and negative lead of the front, negative plates mentioned above, from which they are removed from their webs to the lower surface of the housing, and reduce the active substance on the plate.

2, polar plate vulcanization. What is a polar vulcanization: the so-called plate vulcanization is a lead-cured state of the sulfate on the electrode plate. The active material of the positive and negative plate mentioned above was discharged, and the sulfate was reduced for a long time, and the pure lead, the time was long, and it turned into a structurally tightly, white crystals whose crystal grain was large.

Fourth, the reason for the frequent failure of the battery 1, the cause of the active material falls off, one is the frequent high current discharge (such as frequent starting), so that the surface of the plate is sharply generated in uniform sulfate, due to the lead of sulfate Big size, causing polar bending. The more frequently discharged the large current, the more serious the polar bending. In this way, the polar is more frequent, the active substance above is folded down, and the bottom of the housing is falling.

The second is that the vehicle is overwhelming (such as a deceleration belt) or high-speed walking in an uneven road, the active material falls off, etc. The third is overcharge, discharge, over charge and discharge, easy to make polar panels and have a large amount of bubbles to damage to the active material active substance. 2, the reason for the cause of polar plate vulcanization is important because the battery is in a long-term loss of the loss or a half loss (such as a short drive or long-term parking), so that the cells generated after the plate is discharged for a long time.

The longer the time, the longer the lead, the tight sulfate is very tight, resulting in a long time, causing even if it is recharged, it cannot be reduced to the original neutral lead and sponge pure lead (just like a person in the hands of people. Time washing is not thorough, and the same thing on the hand is the same, and then I want to remove it.).

V. V. Active material falls off and polar vulcanization on the battery of the battery.

1. The active substance falls off, which makes the effective substance of the participating and discharge reactions, and the total storage capacity of the battery is insufficient, that is, the battery is also charged and dissatisfied with the battery, resulting in battery Shorten the service life, premature news fees. 2, after the plate is vulcanized, it is difficult to restore it to the original active substance when charging, so that the storage capacity of the battery is insufficient, that is, how to charge it, it is not charged, the service life is shortened, and the morning newspaper fee.

That is, some people often say that my battery is not used, how can I not do it? This is right, the more you don't have to have your life, not damaged but vulcanization, that is, the restore is not previously state. Sixth, the main points and precautions to extend the service life of automobile batteries pass the above analysis, I think everyone should understand, want to extend the life of the car battery, one is that when the speed of speed is taken and driving in a non-flat road, it should try to slow down as much as possible. , Try to prevent the impact of electrolyte caused by an emergency plus, deceleration.

The second is to prevent over charge, discharge. Third, the battery is supplemented in time, and often keeps the battery in the fully electrical state, even if the battery is not used for a long time, it is necessary to charge once in a period of time (because the battery has self-discharge characteristics, even if it does not need to reduce itself, no Timely charging, phenomena in the lead in the forestead of long-term sulfate). .
