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, device and computer equipment for dynamically adjusting the floating charging current of a lead-acid storage battery. Wherein, the method includes: dynamically adjusting the float charge current of each battery in the lead-acid battery, making the float charge voltage reach a preset threshold, and configuring the lead-acid battery according to the preset threshold that makes the float charge voltage reach. The charging current of the battery is partially or partially lost, and according to the configuration of the charging current of the lead-acid battery partially or partially lost, the charging current of the lead-acid battery is dynamically controlled, so that the float charge voltage of the lead-acid battery is stabilized at the standard float charge pressure within the preset range. Through the above method, it is possible to completely solve the overcharge problem of the batteries in the lead-acid battery pack, and to control the floating charge voltage of each battery in the lead-acid battery pack to a preset threshold.

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] Lead-acid batteries reduce active substances during charging, so that lead sulfate is reduced back to lead dioxide in the positive electrode, lead and sulfuric acid in the negative electrode. However, the charging voltage is the key to determine the reduction ratio of lead sulfate crystals. If the charging voltage is low, new lead sulfate crystals will be formed. If the charging voltage is high, the internal reaction will be violent, resulting in heat loss and water loss, resulting in an increase in acidity, a rise in voltage, and a decrease in capacity. In the backup energy storage lead-acid battery, the normal working state of the lead-acid battery is the floating charging state, that is, a voltage is applied to both en...
