The present invention relates to a battery diagnostic apparatus of a battery regenerator, and more particularly, to enable the diagnosis of a battery by enabling measurement of a reserved capacity (RC) and a cold cranking amps (CCA) of a battery in the battery regenerator. Therefore, the present invention relates to a battery diagnosis apparatus of a battery regenerator for determining a regeneration degree or regeneration of a battery regenerator and preventing waste of time and time required for regeneration of a non-regenerated battery.

BACKGROUND ART In general, batteries (eg, lead-acid batteries) are used in various industrial machines, ships, and the like, such as automobiles, and the batteries are repeatedly charged and discharged by power generated by a generator. And various industrial machines and apparatuses.

If the battery is repeatedly charged and discharged for many years, the battery's electrolytic function drops sharply due to various causes occurring inside the battery, and thus the battery can no longer function as a battery, and thus finally disposed of as industrial waste. It will be disposed of.

A lead-acid battery as such a battery is composed of a negative electrode (Pb) having a high ionization tendency, a positive electrode (PbO 2 ) having a low ionization tendency, and an electrolyte solution (dilute sulfuric acid) filling between the negative electrode and the positive electrode. Will be generated. The lead-acid battery in the state of charge exists in the state of the electrolyte solution of dilute sulfuric acid and water, and is separated into hydrogen ions and sulfate ions by the ionization action. Therefore, the negative electrode and the positive electrode are discharged while forming lead sulfate (PbSO 4 ) through ionic bonding, and the specific gravity of the electrolyte is gradually lowered.

In addition, the charging process of the discharged lead-acid battery proceeds in the reverse order of the discharge process, thereby changing the electrolyte to the state of dilute sulfuric acid and water, and as a result, the specific gravity of the voltage and the electrolyte increases again. However, in lead-acid batteries of this principle, when charging and discharging lasts for several years, the electrodes of the positive electrode and the negative electrode change to lead sulfate, and in this process, white lactic acid softening occurs on the surface of the lead sulfate. . Therefore, a thin film is formed on the electrode to reduce the conductivity of the electrode, the thin film is reduced lead peroxide, it is difficult to recover the electromotive force due to the low concentration of the electrolyte. As a result, it becomes impossible to charge the lead acid battery.

Thus, it was necessary to develop a device for restoring the function of the lead-acid battery, which has become impossible to use. Due to such a need, a "battery regeneration device" of Korean Patent No. 1003881 has been disclosed. Switching Mode Power Supply (SMPS) for receiving an AC voltage and supplying a DC voltage for driving each component of the battery regeneration device and charging the battery; A high pressure pulse generator configured to receive a DC voltage supplied from the SMPS and to generate a high pressure pulse for removing the sulfate from the battery to be charged and for charging the battery; A voltage / current measuring circuit unit for measuring a current flowing into the battery side by detecting a voltage at both ends of the shunt resistor when the high voltage pulse generated from the high voltage pulse generator is introduced into the battery side; A switching unit for connecting or disconnecting the battery to the high voltage pulse generator by a selective switching operation, or for connecting or disconnecting the battery to the load resistance; A polarity test circuit electrically connected to the switching unit and detecting whether the polarity of the battery connected to the device is forward or reverse; When connected to the battery according to the switching operation of the switching unit, the power supply is directly supplied from the battery and operates for a predetermined time, through which the load resistance for determining whether the battery is abnormal; A current limiting circuit section for adjusting the output current from the SMPS; It controls the operation of the components constituting the device and monitors the status, limits the output current value from the SMPS to within the capacity of the battery for a predetermined time through the current limiting circuit, and switches the battery to the high voltage pulse generator through the switching unit.
