Abstract

A power supplying system that includes a power supplying mechanism, an electric load, a power line, and a storage pack. The power supplying mechanism supplies a DC power. The electric load is connected to the power supplying mechanism by the power line. The storage pack is connected to the power line. The charging/discharging curve of the storage pack has a step difference that passes through the rated voltage of the power supplying mechanism. An average discharging voltage on a lower-SOC side of the start point of the step difference is −20% or more of the rated voltage. An average charging voltage on a higher-SOC side of the end point of the step difference is +20% or less of the rated voltage.
