Abstract
Electrification of commercial heavy vehicles has led to the offer of different electric drive-based powertrain architectures, most of them with the adaptation of the diesel engine based architecture. Due to the limited driving range possible, optimal configuration of the powertrain becomes a vital task with the battery as the energy source, which also takes a significant portion of payload capacity. A modular and distributed powertrain architecture using separate cruise and startability axles is introduced in this paper with the aim to maximise driving range. The concept is developed and evaluated using a joint hardware and control design framework for a target vehicle combination of 36 tonnes over a typical regional long haul drive cycle using simulations. Sensitivity study of gear ratios and motor sizes with vehicle target requirements is performed to identify the optimal configuration for the powertrain concept. The simulation results show that by configuring around 50% of the total electric machine power to the cruise axle and choosing a gear ratio between 12-13, the range capability is maximised, while satisfying startability and cruise mode operations.
