ABSTRACT:
The present invention is a battery pack with BMU mounted in the control circuit for controlling battery voltage, etc. In order to avoid worsening of the battery pack durability due to failure of suspension of charging when full-charge detection or over-charge detection is not executed at all because of trouble in the battery voltage measuring section, the battery pack comprises a self-checking section which integrates the charging capacity during charging and detects whether or not the charging capacity is higher than a set-value and turns OFF the charging FET, thereby executing the trouble checking of charging capacity.
