Abstract

Nowadays, mobile devices are used more and more, and their battery lifetime is a key concern. In this paper, we concentrate
on a method called battery scheduling with the aim to optimize the battery lifetime of mobile devices. This technique
has already been largely theoretically studied in other papers. It consists, for systems containing multiple batteries,
in switching the load from one battery to the other. Then, while following a given scheduling sequence, advantage can be
taken from the recovery and rate capacity effects. However, little studies with experimental data of battery scheduling
have been found. In this paper we describe a simple setup for measuring the possible gain of battery scheduling, and give
some exploratory results for two types of real batteries: a smart Li-Ion battery used in the Thales personal communication
system and a more commonly used NiCd battery. The results, so far, show that system lifetime extension is not systematic,
and generally can only reach less then 10%.
