Abstract
본 발명에 의한 전지용량 예측방법에서는 사용전류에 따라 사용가능한 전지용량을 자연대수률 이용하여 예측함으로써 푸케방정식을 비롯한 기존의 방법에 비해 적용이 간편하며 그 정확도가 향상되는 잇점이 있다.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제3도는 본 발명에 의한 자연대수를 이용한 방전전류별 전지용량 예측방법을 설명하기 위한 플로우챠트이다.
Claims (3)
- 잔존용량을 측정하고자 하는 전지의 방전 순간전류를 읽어들여 전지의 총사용량을 계산하는 제1단계 : 다음 제1식과 같은 자연대수를 적용한 방정식C = a × ln (I) + b (1)(여기서 a, b는 실험결과를 통해 얻는 상수이며, I는 순간전류)으로부터 전지의 순간용량을 계산하는 제2단계; 상기 순간용량의 누적용량에 대해 샘플수로 평균을 내어 전지의 사용가능용량을 계산하는 제3단계; 및 상기 전지의 총사용량을 상기 사용가능용량으로 나누어 전지의 잔존용량을 계산하는 제4단계를 포함하는 것을 특징으로 하는 자연대수를 이용한 방전전류별 전지용량 예측방법.
- 제1항에 있어서, 상기 방법은 상기 잔존용량이 0인가를 판단하여 0이면 본 플로우챠트를 종료하고, 0이 아니면 처음 단계로 복귀하여 제1 내지 제4단계를 반복하는 제5단계를 더 포함하는 것을 특징으로 하는 자연대수를 이용한 방전전류별 전지용량 예측방법.
- 제1항에 있어서, 상기 자연대수 방정식을 산출하기 위하여 2개 이상의 기준전류를 사용하는 것을 특징으로 하는 자연대수를 이용한 방전전류별 전지용량 에축방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
