Abstract

A power storage pack having a charge/discharge curve with a step passing through the range of (12.5×n) V to (12.8×n) V, where n is a natural number of 1 to 125. The average discharge voltage on the lower SOC side of the start point of the step of the charge/discharge curve for the power storage pack fails within the range of (9.0×n) V to (12.5×n) V. The average charge voltage on the higher SOC side of the end point of the step of the charge/discharge curve for the power storage pack falls within the range of (12.8×n) V to (14.8×n) V.
