Embodiment Construction
[0052] It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0053] In the following description, use of a suffix such as 'module', 'part' or 'unit' provided to represent an element is only to facilitate description of the present invention and has no specific meaning by itself. Therefore, "module" and "component" may be used mixedly.
[0054] Such as figure 1 As shown, the first embodiment of the present invention provides a method for activating a lead-acid battery, comprising steps:
[0055] S11, start;
[0056] S12. The deviation between the internal resistance value of the cells in the battery pack and the average internal resistance reference value of the battery pack is greater than the first preset value, or the deviation between the internal resistance value of the single cell and its initial internal resistance value is greater than the second prese...

Disclosed is a method and system for activating a lead-acid battery. The method comprises: marking a battery cell as a first battery cell when a deviation between an internal resistance value of the cell in a battery pack and an average internal resistance reference value of the battery pack is greater than a first preset value, or a deviation between the internal resistance value of the cell and an initial internal resistance value of the cell is greater than a second preset value; determining whether the first battery cell exists in the battery pack; if yes, determining whether the battery pack is in a floating charge state; and if yes, performing an activation operation on the first battery cell, the activation operation comprising at least one activation treatment, and the activation treatment comprising circularly recharging and discharging the first battery cell multiple times by using a current of a preset frequency and a preset time sequence within a preset time period. The present invention does not need to de-energize a load of a battery pack during an activation operation, and does not affect other normal cells, thereby effectively improving the power supply reliability of an overall machine room base station.
Description
technical field [0001] The invention relates to the technical field of improving lead-acid batteries, in particular to a method and system for activating lead-acid batteries. Background technique [0002] At present, the common practice of battery management and maintenance is to monitor the voltage of the battery cells in real time, and periodically charge and discharge the battery pack with high current to ensure the service life of the battery. However, this high-current activation method needs to first cut off the battery pack load and then discharge and charge the battery pack, which takes a long time and requires another set of backup battery packs to ensure the continuous power supply of the UPS, and it needs to be controlled manually. and monitoring. Contents of the invention [0003] The main purpose of the present invention is to propose a method and system for activating lead-acid batteries, aiming at automatic real-time monitoring of the battery status and act...
