DEVICE AND METHOD FOR LENGTHENING LIFE SPAN OF STORAGE BATTERY BY ADJUSTING AMPLITUDE OF PULSE CURRENT ACCORDING TO STORAGE POWER STATUS

摘要

The present invention relates to an apparatus and a method for extending the life of a battery for adjusting the magnitude of a pulse current according to an electrical storage state. The present invention relates to an apparatus for extending the life of a battery connected to a battery. An operating voltage setting unit for setting a voltage; An operating voltage comparing unit which compares an externally input voltage with an operating voltage set by the operating voltage setting unit; A battery voltage detector detecting a charge voltage of the battery; A battery voltage comparing unit comparing the output voltage of the battery voltage detecting unit with a reference voltage; A pulse control signal generator for outputting an operation control signal in response to an output signal of the battery voltage comparator, and adjusting an on time of the operation control signal according to the magnitude of the output signal of the battery voltage detector; And a DC pulse generator configured to generate a DC pulse current in response to the pulse control signal output from the pulse control signal generator and apply the DC pulse current to the storage battery, and to adjust the magnitude of the DC pulse current according to an on time of the pulse control signal. In this case, when the state of the battery is bad, the magnitude of the pulse current is increased, and in the case of good condition, the magnitude of the pulse current is reduced to suppress the flow of unnecessary current, thereby effectively extending the life of the battery.
