The parameter analysis of 80 cells from Panasonic by CiS. (a) discharge/charge curves; (b) The statistics of the voltages at the end of charge (Vc-end), at the end of discharge (Vd-end) and at the point of 30 min rest after discharge (Vd-30min), respectively. Their relative standard deviations (δ) were 0.09%, 0.93% and 2.14%, respectively. The instrument error was 0.5% for 5 V range measurement.
