摘要： The present invention teaches methods and systems for detecting internal battery abnormalities during charging and discharging states. The embodiments of the invention includes a circuit for determining charging and/or discharging state of the battery, a circuit for sampling the battery voltage at sequential time points, a circuit for measuring the decline of the voltage, a counter for counting Tdec the time while the voltage is in decline, a circuit for measuring the rate of the decrease of the voltage, a circuit for producing an indicator for internal abnormality if one or more of the following conditions is met: (a) the battery is in the charging state and Tdec exceeds a predetermined time; (b) the battery is in the charging state and the decrease of the voltage exceeds a predetermined voltage; and (c) the battery is in the discharging state and the rate of the decrease of the voltage exceeds a predetermined decline rate.
