Check and solution for battery failure

First, you can connect the charging loop to the rechargeable loop, and the charger should be replaced immediately. The dry battery should be added to the pure water or 1.050 sulfuric acid to maintain charging, and the battery capacity is recovered.

If it is found that there is no inverse sulfate, the capacity should be restored. Second, the maintenance charges for dry battery after the addition of liquid charging should be controlled: the maximum current 1.8a is controlled, charged at 10-15 hours, each group (3, 4) The charging voltage of the battery is controlled in 14.

7V / only or more Be. The variation of the battery deformation battery is due to the continuous number of batteries, and the water is less, and the battery appears: 1. The heat capacity is reduced, the maximum heat storage is the largest water, the water loss, the battery heat capacity is greatly reduced, and there is an emergence The heat is so fast that the battery temperature is rapid; 2.

The oxygen channel becomes smooth, the oxygen that appears in the positive electrode is easy to reach the negative electrode through the channel; 3. The battery adhesion to the positive and negative plate is deteriorated, the internal resistance is increased, and the heat is increased during the charge and discharge process. The temperature is extremely rapid, forming a vicious circle, that is, the so-called thermal out of control, the final temperature reaches 80 degrees, resulting in deformation of the outer casing.

A fault check and identification: a set of batteries If they simultaneously deformed, consider the problem of replacing the charger. There is only one or 2 modifications in a set of batteries, there is a possibility of these faults: 1. The battery charge is inconsistent, and some battery overcharge causing deformation when charging.

It may also be a short circuit single-handed, or some self-discharge conditions. 2. Battery When the polar plate is irreversible sulfate, the internal resistance is increased, and the charging heat is deformation.

3. Battery When connecting, the reaction is caused to heat generation deformation. 4.

The battery does not replenish the addition of the electrolyte to cause the lack of procedure, and finally the green light is not turned on due to charging, causing deformation. Solition and processing of secondary faults: 1. On the basis of ensuring unlilled liquid, add more liquid as much as possible to extend or guard the occurrence of heat loss.

2. Alert has an internal short circuit or a micro short circuit, and it has a tendency to tend to. 3.

During use, try to excessively discharge the occurrence of excessive discharge, and keep your battery storage. 4. Talkually check the charger, there must be no more rechargeable things.

If charging at high temperatures, be sure to ensure that the battery is dissolutely dissipated. To this end, it is necessary to take a method of cooling measures or shorten the charging time. Otherwise, stop charging.

The battery pack is unbalanced to handle the balance of battery packs is a world-oriented problem. Its protocol is a variety of. Inspection and solution for faults 1.

First use the battery to fully charge, then discharge with 2 hour rate. During the discharge process, the voltage of the battery is constantly measured, and the backward battery of the discharge capacity is selected to be solved. 2.

First pose a 1.050 dilute sulfate to just see that there is a flow electrolyte, and then continuously charge 12-15 hours. Pay attention to the temperature of the battery should not exceed 50 ¡ã C during charging.

After the charging is over, stand for 0.5-4 hours, re-use 2 hour rate discharge. During the discharge process, the value of the single voltage is measured.

If the discharge time does not reach the standard, or there is a maximum difference between the longest discharge time in the entire battery, the charge and discharge program operation is also required to meet the requirements. until. If it is repeated charge and discharge cycle, the battery capacity has no declaration or is still 0V left and right low pressure.

This battery is generally short-circuited or active material is severely detached, severe irreversible sulfate, etc., cannot be repaired, should be scrapped. For batteries that meet the requirements, it should be exhausted under a constant voltage 15V / only charge conditions, and the flowing electrolyte, wipe the surface of the battery, the hoodle valve, adhesive with PVC or chloroform adhesive Fit.

One factor in battery life is chemical composition. Everyone has heard of lithium-ion batteries, or lithium polymer batteries, but these vocabulary is too spread - just like the same accuracy of the internal combustion engine. Are you talking about gasoline engines or diesel engines, or a natural gas engine? Lithium ions (en.

wikipedia.org/wiki/lithium-ion_battery) refers to a battery that uses lithium ions to transmit charges. This includes actual battery chemistry composition very a wide range.

Lithium polymer (en.wikipedia.org/wiki/lithium_polymer_battery) or LIPO, only means a battery pack unit with lithium ion chemical ingredients.

The most important thing is the actual chemical component that reacted in the battery. It is generally involved in these: lithium cobaltate (LiCoO2, ICR) lithium manganate (LiMn2O4, IMR) Nickel-cobalt aluminum (liniMNCO2, NCA) Nickel manganese cobalt (liFePO4, LFP) lithium titanate (LTO) ) Or have a variant of this. Then, a given battery chemical composition, there are other things that have great impact on power, energy, and life expectancy.

Details of the anode and cathode construction / structure, specific mixtures, and additives (significantly affecting the performance of the battery) differ in different manufacturers, even between different battery products of the same manufacturer. Unfortunately, most of these details are not casually found on the Internet. Ideally, we hope that the battery has a high energy density of ultraever x (more energy per unit weight or volume storage), the power density of ultraruff X (energy can be released in unit time), and unlimited cycle life (can be used They didn't have any capacity loss until the end of the universe.

Of course, in that universe, the unicorn will also pull out the rainbow ice cream (www.youtube.com/watch?v =ybywhdlo43q) is very unfortunate, we don't live in the Utopian universe.

We do not follow physics, chemical law, in our universe, usually: you can have more this, but on the other hand, less. If you want the fish and bear's own, then the cost will die. So, we are not in time, there is a huge factor in choosing electric vehicles.

No one will spend a million US dollars to buy an electric car in the Nissan Listening to the wind, even if the battery is chemical. Therefore, we continue to choose the actual, affordable chemical composition.
