Modeling, analysis and feasibility study of new drivetrain architectures for off-highway vehicles

摘要

Electrified powertrains/propulsion systems have gained a significant interest in transport industry to develop energy-efficient vehicular systems. In these powertrains, rechargeable energy storage systems (such as High Energy Batteries, Electrochemical Double-Layer Capacitors or High Power Batteries), electric motors, energy management strategies and advanced power electronics converters play an important role in the development of new generations of clean vehicles. Therefore, this paper proposes new drivetrain architectures for Straddle Truck Carriers, as one of off-highway vehicles, which are used in harbors to move containers, in order to improve the Straddle Truck Carriers drivetrain efficiency and to reduce the greenhouse emissions as well as the energy bills. The proposed drivetrains are: (1) series hybrid Straddle Truck Carrier based on a small rechargeable energy storage system (option A), (2) series hybrid based on a reduced internal combustion engine (option B), (3) full electric drivetrain, and (4) new full electric drivetrain based on dynamic wireless-power transfer system.
