Applications of heavy-duty electric vehicles are growing as clean and efficient options in commercial and military fields. Except for the commercial applications, zero exhaust and noise emissions with high powertrain efficiency are aimed for secret operations from military purpose vehicles. In this study, electrification of a heavy military vehicle is simulated by MATLAB/Simulink to achieve these requirements for various powertrain types as wheeled, half-tracked, and tracked. The simulations are performed for the results of electric motor (EM) torque, battery power, and state of charge (SOC) outputs of the vehicle alternatives during the drive cycle time. The results indicate that a higher range can be obtained by the tracked vehicle when it operates at low speeds (HHDDT-creep mode) but the wheeled alternative offers higher ranges in HHDDT-cruise mode for various vehicle weights.
