Abstract
The present invention relates to an apparatus for protecting a secondary battery by preventing overcharge of the secondary battery.The apparatus for protecting a secondary battery includes: a secondary battery; a power supply, connected with both electrode terminals of the secondary battery, for providing a charging voltage and a charging current to the secondary battery to charge the secondary battery; and a secondary battery protection unit for shorting the power supply thereby to stop charging the secondary battery if a charging voltage of the secondary battery is above a predetermined voltage.
