Abstract

The present invention discloses an apparatus and method for detecting a deteriorated battery cell including a measurement unit that measures a state of a battery, an estimation unit that estimates a state of health (SOH) of the battery, a diagnosis setting unit that sets a diagnosis start condition, a diagnosis section, and a determination condition of the deteriorated battery cell according to the SOH of the battery, a diagnosis performance decision unit that determines a detection performance condition of the deteriorated battery cell after an end of charging/discharging of the battery, and a deterioration determination unit that determines the deteriorated battery cell by calculating a voltage difference in the charging and discharging end section and comparing the measurement value with a set value.
