Abstract

Extending the lifetime of battery is a very important goal in battery-operated systems. The prior works of lifetime management mainly focused on single battery, multi-battery scheduling as another way of prolonging the battery lifetime is considered here. Battery Aware Tasks Allocating Algorithm (BATA) for multi-battery operated system is proposed in this paper. It extends the battery lifetime through making fully use of the idle time of battery scheduling which can reduce the charge loss since the recovery effect of battery. Experimental results indicate that BATA can achieve 15.67% ~ 25.43% reductions on the charge loss and 30.68%~55.63% gains of battery lifetime while maintains a low level computation complexity.
