碩士 === 國立臺灣大學 === 電子工程學研究所 === 106 === The broad applications of lithium-ion batteries in cyber-physical systems attract intensive research on building energy-efficient battery systems. Reconfigurable battery packs have been proposed to improve reliability and energy efficiency. Despite recent efforts, how to simultaneously maximize battery usage time and minimize switching count during reconfiguration is rarely addressed. In this work, we devise a control algorithm that, under a simplified battery model, achieves the longest usage time under a given constant power-load while the switching count is at most twice above the minimum. It is further generalized for arbitrary power-loads. Simulation experiments show promising benefits of the proposed algorithm.
