Beschreibung
Zusammenfassung:	The present invention relates to a battery data preprocessing method and system for diagnosing the condition of a battery and a battery condition prediction system, wherein the battery data preprocessing system comprises: a data analysis unit for performing, with respect to battery data including at least one of voltage, current, and temperature, at least one preprocessing among outlier preprocessing for removing an outlier or replacing the outlier with a preset first value, missing value preprocessing for removing a missing value or replacing the missing value with a preset second value, correlation coefficient reporting processing for calculating a correlation between data, and noise reduction processing for recovering data with mixed noise; and a data size conversion unit for normalizing and standardizing the battery data preprocessed by the data analysis unit and inputting the battery data into a pre-trained artificial intelligence model for predicting the condition of a battery. According to the present invention, the accuracy of battery condition diagnosis can be increased. 본 발명은 배터리 상태 진단을 위한 배터리 데이터 전처리 방법 및 시스템, 그리고 배터리 상태 예측 시스템에 관한 것으로서, 전압, 전류 및 온도 중 적어도 하나를 포함하는 배터리 데이터에 대하여, 이상치를 제거하거나 상기 이상치를 기설정된 제1 값으로 대체하는 이상치 전처리, 결측치를 제거하거나 상기 결측치를 기설정된 제2 값으로 대체하는 결측치 전처리, 데이터 간의 상관관계를 산출하는 상관계수 보고 처리 및 잡음이 섞인 데이터를 복구하는 잡음 저감 처리 중 적어도 하나의 전처리를 수행하는 데이터 분석부; 및 상기 데이터 분석부에 의해 전처리된 배터리 데이터를 정규화 및 표준화하여, 배터리의 상태를 예측하는 기학습된 인공지능 모델에 입력하는 데이터 크기 변환부를 포함한다.
