Abstract
A battery diagnosing apparatus includes a battery sensing unit configured to generate a voltage detection signal indicating voltage of a target battery and a current detection signal indicating current of the target battery. The battery diagnosing apparatus also includes a battery diagnosing unit configured to generate a measurement voltage profile representing the correspondence between an accumulated capacity and the voltage of the target battery in a period of interest by monitoring the voltage and current of the target battery while the target battery is being charged or discharged and diagnose abnormality of the target battery by comparing the measurement voltage profile with a criterion voltage profile.
