Title:
APPARATUS AND METHOD FOR DIAGNOSING BATTERY STATE
Document Type and Number:
WIPO Patent Application WO/2024/063575
Kind Code:
A1
Abstract:
An apparatus for diagnosing a battery state according to one embodiment of the present invention comprises: a voltage measurement unit configured to measure a voltage of a battery and, when the measured voltage reaches a first reference voltage set in advance , measure a target voltage for the battery; a resistance measurement unit configured to measure a target resistance of the battery when the measured voltage reaches a second reference voltage set in advance ; and a control unit configured to determine a voltage increase/decrease pattern for the target voltage on the basis of a voltage profile in which the target voltage is stored, determine a resistance increase/decrease pattern for the target resistance on the basis of a resistance profile in which the target resistance is stored, and diagnose the state of the battery from the voltage increase/decrease pattern and the resistance increase/decrease pattern according to a preset diagnostic rule.
