Method, device and system for maintaining storage battery

Abstract

The embodiment of the invention discloses a method, a device and a system for maintaining a storage battery. In the embodiment of the invention, frequency points of a sweep frequency phase shift power pulse wave which can generate resonance with lead sulfate crystals are set according to different resonance points of the lead sulfate crystals of different sizes in a storage battery electrolyte; the crystals are subjected to resonant processing, sharp pulse current is generated under the control of the pulse wave to crush the crystals subjected to the resonant processing, and the crushed crystals are dissolved into the electrolyte of the battery, so that the small-granular lead sulfate crystals are converted into lead and lead dioxide during the charging and discharging of the storage battery in the input process of the sharp pulse current; and thus, the aim of maintaining the performance of the storage battery is fulfilled.

Description

technical field [0001] The present invention relates to the technical field of battery maintenance, and more specifically, to a storage battery maintenance method, device and system. Background technique [0002] With the continuous growth of domestic wireless communication and the development of overseas communication in recent years, the usage of mobile base station communication equipment has been increasing, and the usage of base station batteries, as a necessary device to provide electric energy for base stations, has increased accordingly. When the battery of the base station is being discharged, lead sulfate crystals will be produced on the positive and negative plates. Under normal circumstances, the lead sulfate crystals are fine and evenly distributed on the porous active material. When charging, the positive electrode is reduced to lead dioxide by contact with the electrolyte, and the negative plate is reduced to velvet lead. Due to the existence of anodic oxidati...

AI Technical Summary

Problems solved by technology

When charging, the positive electrode is reduced to lead dioxide by contact with the electrolyte, and the negative plate is reduced to velvet lead. Due to the existence of anodic oxidation on the positive electrode, lead sulfate is easily converted to lead dioxide during charging, while the negative electrode will be due to the presence of anodic oxidation. Long-term power loss storage, deep discharge or insufficient charging cause a poorly conductive coarse crystalline lead sulfate layer formed by fine crystalline lead sulfate on the plate. The coarse crystalline lead sulfate layer is insoluble in the electrolyte and adheres to the surface of the negative plate to cause blockage The micropores in the active material of the plate cause the decline of battery storage and discharge capacity. From the current usage of base station batteries, most base station batteries have only about 50% of their nominal capacity after 1 to 4 years of operation. Far short of design life

[0003] The existing maintenance methods for base station batteries mainly include hydrotherapy, high-current charging and adding activators. The hydrotherapy uses adding water to the battery to dilute the electrolyte and repeatedly charging and discharging to achieve battery repair. However, for the deterioration caused by vulcanization The repairing effect of the storage battery is poor; the high-current charging method adopts the method of using high-current charging to generate negative resistance breakdown and dissolve the lead sulfate crystals in the storage battery, and this method brings about aggravating the problems of dehydration and softening of the plates during the elimination of vulcanization ; Add activator method to eliminate lead sulfate crystallization by conventional charging method, but this method will cause internal electrolyte imbalance and the performance of the battery after activation has not been fundamentally improved
