A practical battery charge/discharge simulator for future embedded systems including smart grids

Accompanying with the rapid popularization of portable embedded systems, the battery technology continues remarkable improvement to achieve low-cost and long battery life. This paper proposes a practical battery simulator which enables simulation of the battery charge/discharge behavior considering characteristics of the battery such as electro chemical diffusion and voltage decline due to inner resistances, and the experimental result in realistic condition is also discussed. Additionally, application for future smart grid system is described.
