Drive Cycle Simulations of Wheeled and Tracked Heavy-Duty Electric Vehicle Powertrains

Abstract

Heavy-duty electric vehicle applications are becoming more popular in transportation, construction, and military applications because of the emission targets of several countries. Therefore, to obtain an efficient and clean heavy-duty electric vehicle, simulation of the powertrain is performed according to various vehicle weights and drive types for the determination of vehicle performance. In this study, the drive cycle simulation of a heavy-duty electric vehicle is performed by Matlab/Simulink for both wheeled and tracked drive alternatives. Battery power requirements and SOC (State of Charge) history are determined according to the drive cycle of HHDDT (Heavy Heavy-Duty Diesel Truck) Transient Mode and Cruise Mode for constant vehicle weight and battery capacity. On the other hand, the climbing potential of vehicles is calculated during the drive cycle. According to the results, the range of wheeled vehicle is found higher than that of the tracked versions, however, the climbing potential of the tracked vehicle is found more advantageous than that of the wheeled type.
