The operability of a portable embedded system is severely constrained by its supply's duration. The authors propose a novel energy management strategy for a combined (hybrid) supply consisting of a battery and a set of super-capacitors to extend the system's lifetime. Batteries are not sufficient for handling high load fluctuations and demands in modern complex systems. Super-capacitors hold promise for complementing battery supplies because they possess higher power density, a larger number of charge/recharge cycles, and less sensitivity to operational conditions. However, super-capacitors are not efficient as a standalone supply because of their comparatively higher leakage and lower energy density.
