Title: Lead storage battery management system

Description:
TECHNICAL FIELD 
     The following description relates to a lead storage battery management system. 
     BACKGROUND ART 
     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 above description is information the inventor(s) acquired during the course of conceiving the present disclosure, or already possessed at the time, and is not necessarily art publicly known before the present application was filed.

     The same name may be used to describe an element included in the example embodiments described above and an element having a common function. Unless otherwise mentioned, the descriptions of the examples may be applicable to the following examples and thus, duplicated descriptions will be omitted for conciseness. 
     According to an example embodiment,  FIG.  1    is a schematic view of a lead storage battery management system, and  FIG.  2    is a block diagram illustrating a lead storage battery management system. 
     Referring to  FIGS.  1  and  2   , a lead storage battery management system  1  may extend a lifetime of a lead storage battery and provide a service for lifetime extension management to a user. The lead storage battery management system  1  may reduce lead usage and environmental damage caused by lead by extending the lifetime of the lead storage battery. The lead storage battery management system  1  may include a lead storage battery reconditioning device  10 , a measuring device  11 , a controller  12 , and an adjusting device  13 . 
     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 . For example, the controller  12  may perform a machine learning process of repeatedly analyzing operational efficiency of the lead storage battery reconditioning device  10  according to the state of the lead storage battery by storing operation information of the lead storage battery reconditioning device  10  and information measured by the measuring device  11 . The controller  12  may determine matters related to the operations of the lead storage battery reconditioning device  10  and the measuring device  11  based on information on the analysis obtained through the machine learning process to control the operations of the lead storage battery reconditioning device  10  and the measuring device  11 . The controller  12  may include a database  120 , a machine learning module  121 , a determiner  122 , and an adjuster  123 . 
     The database  120  may accumulate the information measured by the measuring device  11 , the operation information of the lead storage battery reconditioning device  10 , and information on the lead storage battery. For example, the database  120  may store the information on the lead storage battery such as serial number, a model name, capacitance, and performance efficiency of the lead storage battery. The database  120  may store information on the state of the lead storage battery such as a voltage, an output amount, an oxide film thickness, and high reconditioning efficiency of the lead storage battery. The database  120  may store information on the operation of the lead storage battery reconditioning device  10  such as a pulse power frequency, a reconditioning time, and an amount of oxide film removed from the lead storage battery. The database  120  may store information received by the adjusting device  13  from the user. 
     The machine learning module  121  may derive an effective operation value of the lead storage battery reconditioning device  10  by repeatedly comparing the operation information of the lead storage battery reconditioning device  10  according to the information measured by the measuring device  11  and the state information of the lead storage battery based on the information stored in the database  120 . For example, the machine learning module  121  may repeatedly learn a reconditioning scheme of the lead storage battery reconditioning device  10 , such as an appropriate pulse power frequency and the output amount, according to the model name of the lead storage battery, the thickness of the oxide film generated in the lead storage battery, and the internal voltage and internal resistance of the lead storage battery stored in the database  120 . Therefore, a more efficient and appropriate reconditioning scheme of the lead storage battery reconditioning device  10  may be determined through repeated learning performed by the machine learning module  121 . 
     The determiner  122  may determine matters related to the operations of the measuring device  11  and the lead storage battery reconditioning device  10  based on the information accumulated in the database  120 . In addition, the determiner  122  may determine matters related to the operations of the measuring device  11  and the lead storage battery reconditioning device  10  based on the information analyzed by the machine learning module  121 . For example, the determiner  122  may determine a measurement frequency of the measuring device  11 , a measurement mode of the measuring device  11 , the appropriate pulse power frequency of the lead storage battery reconditioning device  10 , the intensity of the pulse wave, and power consumption, and the like, based on the information accumulated in the database  120  and the information analyzed by the machine learning module  121 . 
     The adjuster  123  may adjust the operations of the measuring device  11  and the lead storage battery reconditioning device  10  based on a determination by the determiner  122 . For example, the adjuster  123  may adjust the measurement frequency, measurement mode, and the like, of the measuring device  11 . The adjuster  123  may adjust the pulse power frequency, the intensity of the pulse wave, the power consumption, and the like, of the lead storage battery reconditioning device  10 . The adjuster  123  may adjust an electrical energy charging level and a charging or discharging state of the lead storage battery. 
     A series of operations to store the operation information of the lead storage battery reconditioning device  10  operated by the adjuster  123  in the database  120  may be repeated. For example, the database  120  may store the operation information of the lead storage battery reconditioning device  10  according to the state information and the performance information of the lead storage battery. The database  120  may provide information to be referenced and used during reconditioning operations that sequentially occur by building a shared server that stores the operation information of the lead storage battery reconditioning device  10  according to the information of the lead storage battery. 
     The measuring device  11  may measure the thickness of the oxide film generated on the electrode of the lead storage battery, and the controller  12  may determine the output amount of the lead storage battery reconditioning device  10  based on a value of the thickness of the oxide film measured by the measuring device  11 . 
     The adjusting device  13  may be interlocked with the controller  12  and receive operation values of the lead storage battery reconditioning device  10  and the measuring device  11  from the user. The adjusting device  13  may include an input and a display. 
     The input may receive information on the operation values and operation modes of the lead storage battery reconditioning device  10  and the measuring device  11  from the user. For example, the input may include a charging mode of the lead storage battery, the measurement mode of the measuring device  11 , and a reconditioning mode of the lead storage battery reconditioning device  10 . In addition, the input may also receive basic information such as serial number of the lead storage battery, serial number of the lead storage battery reconditioning device  10 , serial number of the measuring device  11 , and the like. 
     The display may visually display input information of the input, the operation information of the lead storage battery reconditioning device  10 , and information stored in the controller  12 . For example, the display may 
     The adjusting device  13  may receive the information on operation modes and operation values of the lead storage battery reconditioning device  10  and the measuring device  11  and visually display the operation information of the lead storage battery reconditioning device  10  and the measuring device  11  through at least one of an application and a wearable device interlocked with the controller  12  through an Internet signal.
