“…In this section, the most common thermodynamic processes in HEVs and the mathematical formulations usually considered for modeling them are reviewed. In this sense, thermodynamic processes in an HEV are frequently modeled by thermal cycles, thus allowing a simplification of their conceptualization making their analysis and optimization significantly simpler [46][47][48][49]. In addition, the analysis of the thermodynamic cycles will allow an understanding of the fundamental trends for the design of the engines.…”

“…By the mathematical model above, the performance of an Otto cycle only depends on the values of K and CR, and therefore it is not affected by the amount of heat provided or the degree of explosion [50]. The influence of such parameters on the thermal efficiency of the Otto cycle is shown in Figure 10 [48,49]. For a given value of K, thermal efficiency notably increases with increasing CR at low values of the compression ratio.…”

The 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.
