Abstract

A system was developed for a series hybrid electric vehicle that is characterized by mechanically separating the engine and axle to thereby enable operation in the optimum electric generation range. This system was developed to vastly improve fuel economy without sacrificing vehicle dynamic performance.The study focused on real-time generating without surplus or deficit in accordance with motor power to improve energy transfer efficiency and decrease the size and weight of the energy storage unit. At the same time, generating efficiency was improved by operating the engine with a minimum Brake Specific Fuel Consumption (BSFC). The system was tested on a 1 500 kg equivalent inertia weight class vehicle whereby it was verified that a 94% fuel economy was achieved in comparison to gasoline-powered vehicles in the same class, while no sacrifices were made to dynamic performance.
