The battery can not be powered up. 1, first check if the loop connection is connected to the contact, carefully check the socket and plugs have a fire arc phenomenon, there is a wireless damage line, etc. 2, the battery is charged, but also to see if the charger is damaged, whether the charging parameters meet the requirements: Different brands, different models of battery requirements for the charger parameters are different, so there are millions to regular channels.
Go to purchase qualified charger products, and there are many electric cars in the home, multiple chargers, don't mix the charger. 3. Also check, whether there is a dry phenomenon inside the battery, and it is a serious lack of projection.
4, finally, check if the polar is vulcanized. The non-reversible sulfate of the plate is referred to that the battery polar plate has a white sulfate in the surface of the discharge process, and its particles are hard, it is difficult to dissolve, and the electrochemical reaction when the battery charge and discharge cannot be carried out. We can pass capacity Detector test, the discharge time does not reach 50% of the specified capacity, is generally irreversible sulfate.
In addition, when charging, the voltage rises especially fast, some single-handed voltage is particularly high, exceeding the normal value; the voltage drop is particularly fast, the battery is not stored, and there is very small. In the above case, it can be determined that the battery has irreversible sulfate. Inspection and processing of faults 1, the charging circuit can be firmly connected to the charger should be replaced immediately.
And the dry battery should be added to the pure water or 1.050 sulfuric acid to maintain charging, and the discharge recovery battery capacity is. If it is found that there is no inverse sulfate, the capacity should be restored in a balanced charging.
2, maintenance charges for dry battery after drying battery: should control the maximum current 1.8a, charge at 10-15 hours, each group (3, 4) The charging voltage of the battery is controlled in 14.7V / or more Be.
The deformation of the battery is due to the continuous increase in the battery charging, and the moisture is less, and the battery appears: 1. The heat capacity is reduced. After the heat storage is the largest, the water is lost, the battery heat capacity is greatly reduced, and there is The heat is so fast that the battery temperature is raised; 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. Inspection and processing of faults 1. Check and identification of faults: A group of batteries are deformable, they should consider 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 causes 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 increases, and the charging heat is deformation.
3. Battery When connecting, it is connected to heat-conducting deformation. 4, the battery does not replenish the addition of the electrolytic solution to cause the lack of procedure, ultimately not to the green light due to charging, causing deformation.
Second, the processing and solution of the fault: 1. 2, prevent internal short circuit or micro short circuit, and with micro short road tendency. 3.
During use, try to prevent excessive discharge generation, often keep foot electricity storage when making batteries. 4, often check the charger, do not have any incident. If it is charged at high temperatures, it is important to ensure that the battery is dissolute.
To this end, a method of cooling measures or shortening the charging time can be taken, otherwise it must stop charging. The battery pack is unbalanced to solve the balance of the battery pack is a world-oriented problem, and now there is basically no one-life solution. The reason is a variety of.
Inspection and processing of faults 1, first perform a general maintenance charge, then discharge with 2 hour rate current. During the discharge process, the voltage of the battery is constantly measured, and the backward battery of the discharge capacity is selected to be processed. 2, first complement 1.
050 dilute sulfuric acid to just see the flow electrolyte, continue to charge 12-15 hours. Pay attention to the temperature of the battery not more than 50 ¡ã C when 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 significant increase in low voltage, and this battery is generally short-circuited or the active substance is severely detached, severe irreversible sulfate, etc., cannot be repaired, should be scrapped.
For batteries that meet the requirements, it should continue to be used under the constant voltage 15V / only charge conditions, the flowing electrolyte, clean the battery surface, the hood valve, adhesive the panel with PVC or chloroform binder Fit.
