Energy Management for Hybrid Electric Tractors Combining Load Point Shifting, Regeneration and Boost

Abstract

Political regulations to increase the fuel efficiency of vehicles are leading to hybrid electric vehicles offering more flexibility for operating the internal combustion engine and increasing the performance. In this paper an energy management for hybrid electric vehicles combining load point shifting based on optimization with regeneration and boost based on heuristics is introduced and the real-time implementation on a hybrid electric tractor is discussed. Simulation results indicate an increased fuel efficiency for transportation tasks.
