Ítem Hybrid Electric Vehicles: A Review of Existing Configurations and Thermodynamic Cycles(MDPI, 2021-07) León, Rogelio; Montaleza, Christian; Maldonado, José Luis; Tostado-Véliz, Marcos; Jurado-Melguizo, FranciscoThe mobility industry has experienced a fast evolution towards electric-based transport in recent years. Recently, hybrid electric vehicles, which combine electric and conventional combustion systems, have become the most popular alternative by far. This is due to longer autonomy and more extended refueling networks in comparison with the recharging points system, which is still quite limited in some countries. This paper aims to conduct a literature review on thermodynamic models of heat engines used in hybrid electric vehicles and their respective configurations for series, parallel and mixed powertrain. It will discuss the most important models of thermal energy in combustion engines such as the Otto, Atkinson and Miller cycles which are widely used in commercial hybrid electric vehicle models. In short, this work aims at serving as an illustrative but descriptive document, which may be valuable for multiple research and academic purposes.Ítem Intrinsic Characteristics of Forward Simulation Modeling Electric Vehicle for Energy Analysis(MDPI, 2022-05-24) Montaleza, Christian; Arévalo, Paul; Tostado-Véliz, Marcos; Jurado-Melguizo, FranciscoThe forward method for modeling electric vehicles is one of the most suitable for estimating energy consumption in different imposed driving cycles. However, a detailed description of the methodology used for the development of electric vehicle models is necessary and is scarce in the current literature. To fill this gap, this study focuses on highlighting the intrinsic characteristics through a theoretical study with a mathematical model, complemented by demonstrative simulations in Matlab/Simulink. The results show that the forward method can be estimated more accurately based on the energy consumption of the electric vehicle. Moreover, this paper aims to be explicitly descriptive for the development of more complex electric vehicle models to incorporate real driving cycles, being able to size the drivetrain of the vehicle itself or develop ecological routes.
