Optimized Design and Analysis of a Series-Parallel Hybrid Electric Vehicle Powertrain for a Heavy Duty Truck

Hybrid electric vehicles are considered as an eco-friendly alternative solution to conventional internal combustion engine driven vehicles. This paper investigates the development of a Series-Parallel hybrid electric vehicle powertrain for a heavy-duty truck based on vehicle performance requirements, and compares its performance with a Series hybrid electric configuration for the same base vehicle. The parameter matching of the vehicle powertrains was followed by optimization in terms of maximizing fuel economy for an Indian highway drive cycle using the software ADVISOR. The simulation results quantified the potential benefits of the optimized series-parallel hybrid electric configuration for a highway drive cycle with respect to the series hybrid electric configuration.
