The method of detecting battery degradation level detects the change in residual capacity (”SOC) for one charging period or one discharging period of a battery 1 being charged and discharged. Weighting factors that establish degradation level according to the value of ”SOC are pre-stored in memory, and based on the stored data; weighting factors are determined from the detected ”SOC to determine the battery 1 degradation level from the weighting factors. The method detects degradation level from a change in the residual capacity (”SOC) detected over one charging period or one discharging period, rather than simply from the current, to allow more accurate detection of the battery degradation level. |
