Vehicle electrification in the form of hybrid electric vehicles (HEVs), plug-in HEVs (PHEVs), extended-range electric vehicles (ER-EVs), and battery electric vehicles (BEVs) is the future for road transportation. Knowledge about drive cycles, which represents in part a vehicle's trip speed and acceleration profile, is essential to, and pervasive throughout, vehicle research. HEV drive cycles present unique challenges, for example, to fuel consumption certification. PHEVs and ER-EVs simply complicate certification even further. Specific objectives of this proposal are to determine the sensitivity of hybrid electric vehicles (HEVs), plug-in HEVs (PHEVs), extended range electric vehicles (ER-EVs), and battery electric vehicles (BEVs) to drive cycle variations with a particular focus on (a) battery management with considerations for battery degradation, end-of-vehicle-life state-of-health (SOH), and second-use, (b) adaptive control strategies for energy efficiency and emissions improvements, and (c) better communicating electrified vehicle energy consumption and emissions to consumers. Underlying the theory, modelling, and experiments is the University of Waterloo five-step holistic cycle model-based design process consisting of model-in-the-loop, software-in-the-loop, hardware-in-the-loop, component-in-the-loop simulations followed by integration realizations and validation within a prototype vehicle. A long term goal of this work is to develop strategies to achieve emission reduction and a sustainable development and sustainable livelihoods future, by meeting Canadian automotive industry and government needs with research that contributes to the Canadian economy. In the short term, the drive cycle void filled by this proposed research will be of global interest, but will also contain Canadian relevant considerations that the worldwide automotive industry might otherwise overlook.
