POWER STORAGE PACK

The present invention is intended to achieve an increase in the life-span of a power storage system, a reduction in the price thereof, and a reduction in size thereof. The charge/discharge curve for a power storage pack 12 has a step passing through the range of (12.5 × n) V or higher and (12.8 × n)...

Beschreibung
Zusammenfassung:	The present invention is intended to achieve an increase in the life-span of a power storage system, a reduction in the price thereof, and a reduction in size thereof. The charge/discharge curve for a power storage pack 12 has a step passing through the range of (12.5 × n) V or higher and (12.8 × n) V or lower (n is a natural number of 1 or more and 125 or less). The average discharge voltage on the lower SOC side than the start point of the step of the charge/discharge curve for the power storage pack 12 falls within the range of (9.0 × n) V or higher and (12.5 × n) V or lower. The average charge voltage on the higher SOC side than the end point of the step of the charge/discharge curve for the power storage pack 12 falls within the range of (12.8 × n) V or higher and (14.8 × n) V or lower.
