The following description relates to a lead storage battery management system.
A lead storage battery is a rechargeable battery that uses lead as an electrode and sulfuric acid as an electrolyte and may be repeatedly used through charging and discharging. A lead storage battery may charge and discharge electrical energy therein through a process of generating and decomposing lead sulfate through reduction-oxidation generated in an electrode. In the course of charging and discharging a lead storage battery, if the battery is left discharged or not fully charged, sulfate is generated on an electrode plate. When there is sulfate on the electrode plate, the electrode plate may not be able to properly function as an electrode plate, and performance of the lead storage battery may deteriorate.
In order to prevent the performance of a lead storage battery from deteriorating due to the generation of sulfate, a strong voltage or current may be applied to an electrode surface of the lead storage battery such that a sulfate film generated on the electrode may be ionized into sulfate ions and lead ions. However, there are disadvantages. The lead storage battery may need to be separated from a product while the sulfate is being removed in the process of applying the strong voltage or current to the electrode surface. Moreover, measuring the lead storage battery and a lead storage battery reconditioning device and managing the lead storage battery may be difficult because an additional measuring instrument is needed to measure the state of the lead storage battery and an operation of a film-removing device. Therefore, there is a need for a system for extending the lifetime of a lead storage battery and effectively managing a lead storage battery.
In this regard, Korean Patent Publication No. 10-0868491 discloses a life continuation system and a method of an accumulator. A life continuation system and a method of an accumulator relate to a technology associated with a device for regenerating a storage battery to prevent crystallized sulfate from accumulating on an electrode plate through a chemical reaction using a pulse wave having a high frequency band.

The lead storage battery reconditioning device 10 may generate a pulse wave current to remove an oxide film generated on an electrode of the lead storage battery. For example, the lead storage battery reconditioning device 10 may remove sulfate generated on the electrode using powerful pulse power. The lead storage battery reconditioning device 10 may remove the sulfate generated on the electrode of the lead storage battery by ionizing the lead sulfate generated on the electrode so that lead ions are stabilized and become lead in an original electrode state and enabling sulfate ions to return to an electrolyte state. The lead storage battery reconditioning device 10 may use pulse power falling within a range of 100 Hertz (Hz) to 990 Hz. The lead storage battery reconditioning device 10 may remove the sulfate by accumulating electrical energy in a condenser and instantaneously supplying a large amount of power to the electrode of the lead storage battery in a short time through switching.
In addition, the lead storage battery reconditioning device 10 may adjust a pulse power frequency, intensity of a pulse wave, and an amount of power to be used. Accordingly, the lead storage battery reconditioning device 10 may receive an operation control signal of the controller 12 to operate in an appropriate operation mode according to a circumstance, thereby increasing power efficiency and efficiently removing the oxide film of the lead storage battery.
The lead storage battery reconditioning device 10 may be coupled to the electrode of the lead storage battery. Therefore, the oxide film generated on the electrode of the lead storage battery may be removed by the lead storage battery reconditioning device 10 without an additional separation operation.
The measuring device 11 may measure information on a state of the lead storage battery. For example, the measuring device 11 may measure an internal voltage and an internal resistance of the lead storage battery. The measuring device 11 may measure electrolyte density in the lead storage battery. The measuring device 11 may measure a degree of formation of the oxide film generated on the electrode of the lead storage battery. The measuring device 11 may measure the degree of formation of the oxide film by measuring the internal voltage, the internal resistance, a temperature, the electrolyte density and a charging level of the lead storage battery.
The controller 12 may receive an operation signal from the lead storage battery reconditioning device 10 and the measuring device 11 to control operations of the lead storage battery reconditioning device 10 and the measuring device 11.
