Hybrid lead-acid/lithium-ion energy storage system with power-mix control for light electric vehicles

Abstract

This work presents a hybrid energy storage system (HESS), using lithium-ion (LI) and lead-acid (PbA) batteries, for light electric vehicles (LEV) that is both cost and performance competitive with single energy storage system (SESS) configurations. A modular I want to express my gratitude to Professor Olivier Trescases for his mentorship, support and guidance. His intellect, attention to detail, and commitment to excellence has been an inspiration over the past two years, and will continue to guide me in future endeavors in my career and life. My work would not have been possible without the efforts of Roger Gerson, Larry Hilligoss, Jennifer Rafiner-Jarboe and everyone else at Brammo, Inc. as well as John Adams of Polaris Industries. Thank you all for your contributions, big or small, to the project.
