Problems solved by technology

[0003] Existing lead-acid batteries, in the state of floating charging, often suffer from dehydration, which increases the concentration of dilute sulfuric acid inside the battery, resulting in an increase in the voltage of the battery itself. In UPS (Uninterruptible Power Supply, uninterruptible power supply) or switch Under the stable floating charge voltage of the power supply, the lead-acid battery with high voltage response will seize the voltage of the lead-acid battery with normal response, so that the lead-acid battery with normal response is insufficiently charged due to the low charging voltage and insufficient reduction of the active material lead sulfate. Crystallization, leading to premature failure of lead-acid batteries
It is precisely because of the overcharge phenomenon of some lead-acid batteries that the service life of the whole set of lead-acid batteries is greatly reduced, and the overcharge phenomenon of lead-acid batteries is very common

Abstract

The invention discloses a method and device for dynamically adjusting floating charge current of a lead-acid storage battery and computer equipment. The method comprises the following steps: dynamically adjusting the floating charge current of each storage battery in the lead-acid storage battery, enabling the floating charge voltage to reach a preset threshold value, and configuring the lead-acidstorage battery to lose the charge current locally or partially according to the preset threshold value which enables the floating charge voltage to reach, and dynamically controlling the charging current of the lead-acid storage battery according to the configured charging current of the lead-acid storage battery which is partially or partially lost, so that the floating charge voltage of the lead-acid storage battery is stabilized within the preset range of the standard floating charge voltage. By means of the mode, the overcharge problem of the storage batteries in the lead-acid storage battery pack can be thoroughly solved, and the floating charge voltage of each storage battery in the lead-acid storage battery pack is controlled to be a preset threshold value.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a method, device and computer equipment for dynamically adjusting the floating charge current of lead-acid batteries. Background technique [0002] When the lead-acid battery is charged, the active material is reduced, and the lead sulfate is reduced back to lead dioxide at the positive electrode, lead and sulfuric acid at the negative electrode. However, the charging voltage is the key to determine the reduction ratio of lead sulfate crystals. Low charging voltage will form new lead sulfate crystals, and high charging voltage will cause violent internal reaction and heat loss, resulting in increased acidity, resulting in increased voltage and decreased capacity. In the backup energy storage lead-acid battery, the normal working state of the lead-acid battery is the floating charge state, that is, a voltage is applied to both ends of the lead-acid battery for a long ...
