THE APPARATUS AND METHOD OF SMART POWER BANK WITH HYBRID CHARGING

摘要

The present invention relates to a hybrid charging method type portable smart power bank apparatus and a charging and discharging method through the same. According to the present invention, the hybrid charging method type portable smart power bank apparatus includes: a step (S200) of turning on a power switch; a step (S210) of checking a state of a charging battery unit; a step (S220) of examining the existence of an external provision power source of the charging battery unit and a suppliable power source of an external power source; a step (S230) of supplying the power source to a variable power source unit or to a fixed power source unit; a step (S240) of selecting the charging battery unit with the lowest number as the charging state of the examined charging battery unit when the variable power source unit is supplied with the power source; a step (S250) of determining the existence of a replaceable charging battery unit; a step (S260) of selecting the charging battery unit with the lowest number as the charging state of the examined charging battery unit when the power is supplied to the fixed power source unit; a step (S270) of determining the existence of the replaceable charging battery unit; and a step (S280) of driving an emergency power source mode in the microprocessor unit, thereby improving a lifespan of a battery.
