EVALUATION METHOD OF SECONDARY BATTERY
A method for evaluating the durability of a secondary battery comprises: a durability step (S4, S5) of applying an alternating current voltage of durable frequencies (fda, fdb, fdc, fdd, fde) to first secondary batteries (Ba, Bb, Bc, Bd, Be) for evaluation in which the temperature and SOC are adjust...

Zusammenfassung: | A method for evaluating the durability of a secondary battery comprises: a durability step (S4, S5) of applying an alternating current voltage of durable frequencies (fda, fdb, fdc, fdd, fde) to first secondary batteries (Ba, Bb, Bc, Bd, Be) for evaluation in which the temperature and SOC are adjusted to the first temperature (Td) and first SOC (SOCd) during durable test periods (Dd1, Dd2); and an evaluating step (S9) of evaluating the durability for battery reaction related to the durable frequencies (fda, fdb, fdc, fdd, fde) during the battery reaction of the first secondary batteries (Ba, Bb, Bc, Bd, Be).
이차 전지의 내구성 평가 방법은, 온도 및 SOC 가 제 1 온도 (Td) 및 제 1 SOC (SOCd) 로 조정된 평가용의 제 1 이차 전지 (Ba, Bb, Bc, Bd, Be) 에, 내구 시험 기간 (Dd1, Dd2) 에 걸쳐, 내구 주파수 (fda, fdb, fdc, fdd, fde) 의 교류 전압을 계속 인가하는 내구 스텝 (S4, S5) 과, 제 1 이차 전지 (Ba, Bb, Bc, Bd, Be) 의 전지 반응 중, 내구 주파수 (fda, fdb, fdc, fdd, fde) 에 관련된 관련 전지 반응에 대한 내구성을 평가하는 평가 스텝 (S9) 을 구비한다. |
