ABSTRACT:
A charging control method and circuit of a rechargable battery, able to achieve full charging of the battery by turning on/off of the battery during a given time control circuit of a recharging battery includes: a battery voltage sensing unit connected to battery inserting unit, for sensing a battery charging voltage connected; an analog/digital converter for digitalizing a voltage value sensed in the battery voltage sensing unit; a central processing unit for sensing whether or not the battery has been inserted from an output value of the analog/digital converter, repeatedly turning on/off during a given time, controlling the current supply, determining whether or not the battery is full charged, and controlling the full charged state to be displayed; a battery charging display unit for displaying the full charge state or state by a value outputted from the central processing unit; a current regulator for supplying the battery with current; a switching regulator for switching an output of the current regulator to be turned during the given time under the control of the central processing unit; and a charging path selecting unit for selecting an output of the switching regulator by the output of the central processing unit and providing the selected output to the battery inserting unit.
