Hybrid Electric Vehicle Characterization Using Generalized Notion of Power

摘要

This paper presents a novel mathematical model based on the generalized notion of power (GNP) to accurately predict the performance characteristics of hybrid electric vehicles (HEVs). The uniqueness of this technique is the ability to represent both internal combustion engine and electrical propulsion machines in one system of state space equations. Thus, it allows proper characterization and control of the interaction of both systems by taking into account large and small load disturbances and the irreversibility of entropy generation by the internal combustion engine. The superiority of the proposed model is demonstrated by applying it to a prototype HEV configuration and by comparison to readily available benchmark data.
