Abstract
The method of detecting battery degradation level detects the change in residual capacity (ΔSOC) 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 ΔSOC are pre-stored in memory, and based on the stored data; weighting factors are determined from the detected ΔSOC to determine the battery 1 degradation level from the weighting factors.
