Hybrid Operating Strategy and Energy Management for a Hybrid Electric Vehicle

Abstract

This paper describes the development of the Low Storage Requirement (LSR) Hybrid Electric Vehicle (HEV) Vehicle System Controller (VSC). It defines the LSR configuration and discusses the advantages of this particular configuration. The main focus of this paper is the hybrid operating strategy for this vehicle and the details of the hybrid operating modes. This hybrid vehicle was developed as a part of the U. S. Department of Energy (DOE) Hybrid Propulsion Systems Development Program that was conducted under a cost-shared subcontract funded equally by Ford and DOE through the Midwest Research Institute which manages and operates DOE’s National Renewable Energy Laboratory in Golden, CO.
