| description | A method for predicting capacity of a battery cell according to the present invention includes: a discharging step of measuring discharge capacity by discharging the battery cell in multiple stages; and a prediction step of estimating the capacity of the battery cell from the measured discharge capacity, wherein the discharging step comprises n number of discharge sections (n is an integer of 3 or more), and the discharge rate of each section of the discharge sections is sequentially decreased.
본 발명에 따른 전지셀의 용량 예측 방법은, 전지셀을 다단계로 방전하여 방전 용량을 측정하는 방전 단계; 및 상기 측정된 방전 용량으로부터 전지셀의 용량을 추산하는 예측 단계를 포함하고, 상기 방전 단계는, n개(여기서 n은 3 이상의 정수임)의 방전 구간들로 구성되고, 상기 방전 구간들의 구간별 방전 속도가 순차적으로 감소하는 것을 특징으로 한다. |
