How is the UPS uninterruptible power supply external battery short circuit caused? UPS battery short circuit system refers to the positive and negative poles of the battery. Battery short circuit phenomena Important in the following aspects: (1) low open circuit, closed circuit voltage (discharge) quickly reaches the termination voltage. (2) When the large current is discharged, the end voltage drops rapidly to zero.

(3) When opening the road, the electrolytic solution density is very low, and the electrolyte in the low temperature environment will have ice phenomenon. (4) When charging, the voltage rises very slow, always maintains a low value (sometimes drop to zero). (5) When charging, the electrolyte temperature rises very quickly.

(6) When charging, the electrolyte density increases very slow or almost no change. (7) When charging, it does not take air bubbles or the gas is very late. The reason for the interior of the UPS uninterruptible power supply external battery is important.

The following aspects: (1) The quality of the partition is not good or defect, allowing the plate active material to pass, causes positive, negative plate virtual contact or direct contact. (2) The partition block is connected to the positive and negative plates. (3) The active substance is expanded from the active material due to excessive deposition of the active substance, resulting in positive and negative plates to connect to the deposits in the lower edge or side edges of the positive, negative electrode plates.

(4) The conductive object falls into the battery, which is connected to the battery. (5) The lead stream formed when the welding pole is not exhausted, or the lead beans are present during the positive and negative plate, and the damper is damaged during the charge and discharge process.
