Vehicle Evaluation, Battery Modeling, and Fleet-testing Experiences in Hawaii

Abstract

Hawaii is an attractive proving ground for electric and hybrid vehicles (EHV) evaluation. Envisioning and embracing the needs for environmental-friendly advanced transportation technology developments, the Hawaii Center for Advanced Transportation Technologies (HCATT) and the Electrochemical Power Systems Laboratory (EPSL) at the Hawaii Natural Energy Institute (HNEI) of the University of Hawaii, are working together to promote and facilitate EHV development in Hawaii. This paper reports some of the recent activities in EHV evaluation, battery modeling, and fleet testing in the HCATT program. The fleet of EHV in this program includes battery-powered EV (BEV) and battery-fuel cell hybrid electric vehicles (HEV). We will present vehicle test results, battery modeling and simulation tool developments, and data analysis approaches that we developed and used in the program.
