Abstract

본 발명의 2차 전지의 잔존용량 연산 방법은 (a) 2차 전지의 개방회로전압 기반의 전압값과 전류 적산에 의해 연산된 잔존용량 값의 평균값을 구하여 이퀄라이징을 수행하는 단계; (b) 상기 2차 전지의 온도와 잔존수명을 연산하는 파라미터를 통해 가감 연산을 수행하는 단계; 및 (c) 상기 단계(a)에서 산출된 2차 전지의 잔존용량 값과 상기 단계(b)에서 연산된 값을 합산하여 실제 2차 전지 잔존용량 값을 도출하는 단계를 포함한다. 본 발명에 의하면, 2차 전지의 잔존용량을 정확히 연산 및 도출하는데 있어 기존 방법 대비 전지의 온도 및 잔존수명을 보상함으로써 최소한의 오차를 갖는 완성도 높은 방법으로 SOC를 산출할 수 있다.
