Battery Diagnostics on Path-Dependent Aging Overview

Under this project, the Hawai‘i Natural Energy Institute (HNEI) is being funded together with the Idaho National Laboratory by the US Department of Energy (DOE). The principal objective is to gain a better understanding of battery life for batteries utilized in operation of electric vehicles. Emphasis is on analysis of existing lithium-ion battery systems and the aging of such batteries under a variety of conditions.

The primary HNEI contact for this project is Bor Yann Liaw. An important benefit of project activities would be a revolution in battery diagnosis and prognosis to provide improved battery management. For project details, see the Battery Diagnostics on Path-Dependent Aging pdf document.

Another project of interest involves operation of specialized GM electric vehicles.  See the Hydrogen for GM Equinox Electric Vehicles project section of our website for details. For information regarding other related HNEI research efforts, see the Electrochemical Power SourcesEnergy Storage, Hydrogen, and Transportation research sections of our website.
