Recent work on battery-driven power management has demonstrated that sequential discharge is suboptimal in multi-battery systems, and lifetime can be maximized by distributing (steering) the current load on the available batteries, thereby discharging them in a partially concurrent fashion. Based on these observations, we formulate multi-battery lifetime maximization as a continuous, constrained optimization problem, which can be efficiently solved by non-linear optimizers. We show that great lifetime extensions can be obtained with respect to standard sequential discharge, as well to previously proposed battery allocation schemes.

Abstract
Recent work on battery-driven power management has demonstrated that sequential discharge is suboptimal in multi-battery systems, and lifetime can be maximized by distributing (steering) the current load on the available batteries, thereby discharging them in a partially concurrent fashion. Based on these observations, we formulate multi-battery lifetime maximization as a continuous, constrained optimization problem, which can be efficiently solved by non-linear optimizers. We show that great lifetime extensions can be obtained with respect to standard sequential discharge, as well to previously proposed battery allocation schemes.Pubblicazioni consigliate
