Because many modern applications are powered by a collection of batteries, new methods reported in the recent literature aim to extend the lifetime of a collection of batteries by using redundant batteries and scheduling a subset of the batteries for discharge. To compare the effectiveness of different strategies for scheduling batteries, we defined a new metric called discharge efficiency. We show that both the lifetime and the discharge efficiency can be improved by using redundant batteries and scheduling strategies. To cope with the uncertainties that come to pass during the discharge process, we formulated the problem of coordinating the discharge of a collection of batteries in the goal-seeking paradigm. This formulation allowed us to design an effective decision-maker to coordinate the discharge. The results in this thesis show that the decision-makers based on the goal-seeking paradigm improve lifetime of a collection of batteries between 12.7% (when the collection supplies constant power to a load) and 21.6% (when the collection supplies constant current to the load). Similarly depending on the discharge scenario, the discharge efficiency is improved by 11.7% to 13.4%. In addition, the new decision-maker utilizes a small number of redundant batteries more effectively than the scheduling methods reported in the literature. 2005 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1133371583 http://rave.ohiolink.edu/etdc/view?acc_num=akron1133371583 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
