Problems solved by technology
[0002] In most DC power supply systems, batteries connected in series are used as an important emergency backup power supply. When the main power supply is cut off, the battery pack will change from the backup power supply to the main power supply to supply power for the load. After the battery has been used for a long time, the capacity will drop seriously and cannot meet The backup time is required to become a waste battery; the waste battery must be scrapped and returned to the factory as early as possible, which will cause environmental pollution and increase the cost of battery use; the waste battery can also be repaired and empowered to meet the backup power requirements; a good battery can be transformed into There are many reasons for waste batteries. Severe crystallization of sulfuric acid on battery plates is an important reason for capacity decline. The conventional repair method of adding sulfuric acid solution cannot solve this problem.
