Abstract

PURPOSE: To prevent malfunction such as the stop of charging of a secondary battery due to noise by judging the output of a comparing means to be a proper output and stopping charging of the secondary battery with electricity, when the duration of the output more than the reference value of the comparing means exceeds a specified period.
CONSTITUTION: An apparatus is provided with a comparing means 13 for obtaining the rate of temperature rise of a secondary battery 8 for each specified period of time and comparing the rate of temperature rise when a reference value to detect that the rate of temperature rise is more than the reference value. Further, a judging means 16 judges the output of the comparing means 13 to be a proper output and stops charging of the secondary battery 8 with electricity, when the duration of the output more than the reference value of the comparing means 13 exceeds a specified period.
