Device for lengthening life span of storage battery by adjusting amplitude of pulse current according to storage power status

摘要

The subject innovation relates to a life extension of the battery to control the magnitude of the pulse-current device in accordance with the power level, the operating voltage setting unit for setting an operating voltage for operating a life extension of the battery device; A voltage input from the external operating voltage comparison unit for comparing the operation voltage set by the operation voltage setting section; Battery voltage detector for detecting a terminal voltage of the storage battery; Battery voltage comparator for comparing an output voltage of the battery voltage detector with a reference voltage; And it outputs an operation control signal in response to the output signal of the battery voltage comparison unit pulse control signal for controlling the on time of the operation control signal according to the magnitude of the output signal from the battery voltage detection occurs; And the pulse in response to the pulse control signal outputted from the control signal generator generates a direct current pulse current, applied to the storage battery, the pulse unit generating a direct current pulse in accordance with the on time of the control signal to control the magnitude of the direct current pulse current If the status of the battery may be bad by having to increase the size of the pulse current and, if the good is to suppress the flow of unnecessary current by reducing the size of the pulse current, effectively extending the life of batteries.
