Solid-State Battery Modeling Case Studies for the Analysis of a Micro-Robot Power System

Recent works by the authors have presented modeling and simulation techniques for analyzing repeated fast dynamic loading of thin-film solid-state batteries. These techniques were developed to address timescale issues in modeling battery discharge under these types of loads. In this paper, we explore various consequences of battery usage in potential micro-robotic applications based on use of these modeling techniques in a series of case studies. Impact of electrochemical versus simple lumped parameter battery modeling is first examined. This is followed by projection of battery performance in basic series versus boost converter arrangements to supply thin-film piezoelectric robotic actuators. Potentially advantageous battery and conversion circuit configurations are identified.
