What are the causes of UPS battery short circuit?
A UPS battery short circuit may be due to poor quality or defective plates, the active material on the plates has expanded and fallen off, or the "lead flow" formed when welding the pole groups has not been removed; common faults include uneven float voltage, battery bulging and deformation, and leakage. fluid or water loss, the following is a detailed introduction to the "Causes and Common Failures of Internal Short Circuits in UPS Batteries".
1. Causes of UPS battery short circuit
1. The separator is of poor quality or defective, allowing the active material of the plate to pass through, causing virtual or direct contact between the positive and negative plates.
2. The active material on the plate expands and falls off. Due to excessive deposition of the fallen active material, the lower edge or side edge of the positive and negative plates come into contact with the sediment, causing the positive and negative plates to be connected.
3. Conductive objects fall into the UPS power battery causing the positive and negative plates to be connected.
4. The "lead flow" formed when welding the pole group has not been removed, or there are "lead beans" between the positive and negative plates during assembly, which will damage the separator during the charging and discharging process and cause the positive and negative plates to be connected.
2. Common faults of UPS batteries
1. Unbalanced floating charge voltage
Valve-regulated lead-acid batteries commonly have problems with uneven float voltage and open circuit voltage deviation. The uniformity of a valve-regulated lead-acid battery refers to the difference between the open circuit voltage measured after the battery is completed and the float voltage of the battery pack in the float state.
2. Battery bulging and deformation
This is a very destructive phenomenon that occurs when valve-regulated lead-acid batteries are used improperly, that is, thermal runaway, which can cause the battery tank to bulge and deform, accelerate water loss, and even damage the battery.
3. Battery leakage
Valve-regulated lead-acid batteries will have leakage problems to varying degrees, mainly in battery tank cover leakage, safety valve leakage, and pole terminal leakage.
4. Battery loses water
Valve-regulated lead-acid batteries work in a "liquid-lean" state, and their electrolyte is completely stored in the porous AGM diaphragm. Once the battery loses water, it will cause the positive and negative electrodes of the battery to come out of contact with the electrolyte in the separator, causing the battery to be unable to discharge electricity.
