Hybrid Electric Vehicles: a Review of Existing Configurations and Thermodynamic Cycles
Review Hybrid Electric Vehicles: A Review of Existing Configurations and Thermodynamic Cycles Rogelio León , Christian Montaleza , José Luis Maldonado , Marcos Tostado-Véliz * and Francisco Jurado Department of Electrical Engineering, University of Jaén, EPS Linares, 23700 Jaén, Spain; [email protected] (R.L.); [email protected] (C.M.); [email protected] (J.L.M.); [email protected] (F.J.) * Correspondence: [email protected]; Tel.: +34-953-648580 Abstract: 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.

Hydrogen Fuel Cell Vehicles in Tunnels
SAND2020-4507 R Hydrogen Fuel Cell Vehicles in Tunnels Austin M. Glover, Austin R. Baird, Chris B. LaFleur April 2020 Sandia National Laboratories is a multimission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525. 2 ABSTRACT There are numerous vehicles which utilize alternative fuels, or fuels that differ from typical hydrocarbons such as gasoline and diesel, throughout the world. Alternative vehicles include those running on the combustion of natural gas and propane as well as electrical drive vehicles utilizing batteries or hydrogen as energy storage. Because the number of alternative fuels vehicles is expected to increase significantly, it is important to analyze the hazards and risks involved with these new technologies with respect to the regulations related to specific transport infrastructure, such as bridges and tunnels. This report focuses on hazards presented by hydrogen fuel cell electric vehicles that are different from traditional fuels. There are numerous scientific research and analysis publications on hydrogen hazards in tunnel scenarios; however, compiling the data to make conclusions can be a difficult process for tunnel owners and authorities having jurisdiction over tunnels. This report provides a summary of the available literature characterizing hazards presented by hydrogen fuel cell electric vehicles, including light-duty, medium and heavy-duty, as well as buses. Research characterizing both worst-case and credible scenarios, as well as risk-based analysis, is summarized. Gaps in the research are identified to guide future research efforts to provide a complete analysis of the hazards and recommendations for the safe use of hydrogen fuel cell electric vehicles in tunnels. -

Comparison of Hydrogen Powertrains with the Battery Powered Electric Vehicle and Investigation of Small-Scale Local Hydrogen Production Using Renewable Energy
Review Comparison of Hydrogen Powertrains with the Battery Powered Electric Vehicle and Investigation of Small-Scale Local Hydrogen Production Using Renewable Energy Michael Handwerker 1,2,*, Jörg Wellnitz 1,2 and Hormoz Marzbani 2 1 Faculty of Mechanical Engineering, University of Applied Sciences Ingolstadt, Esplanade 10, 85049 Ingolstadt, Germany; [email protected] 2 Royal Melbourne Institute of Technology, School of Engineering, Plenty Road, Bundoora, VIC 3083, Australia; [email protected] * Correspondence: [email protected] Abstract: Climate change is one of the major problems that people face in this century, with fossil fuel combustion engines being huge contributors. Currently, the battery powered electric vehicle is considered the predecessor, while hydrogen vehicles only have an insignificant market share. To evaluate if this is justified, different hydrogen power train technologies are analyzed and compared to the battery powered electric vehicle. Even though most research focuses on the hydrogen fuel cells, it is shown that, despite the lower efficiency, the often-neglected hydrogen combustion engine could be the right solution for transitioning away from fossil fuels. This is mainly due to the lower costs and possibility of the use of existing manufacturing infrastructure. To achieve a similar level of refueling comfort as with the battery powered electric vehicle, the economic and technological aspects of the local small-scale hydrogen production are being investigated. Due to the low efficiency Citation: Handwerker, M.; Wellnitz, and high prices for the required components, this domestically produced hydrogen cannot compete J.; Marzbani, H.

How Practical Are Alternative Fuel Vehicles?
How Practical Are Alternative Fuel Vehicles? Many of us have likely considered an alternative fuel vehicle at some point in our lives. Balancing the positives and negatives is a tricky process and varies greatly based on our personal situations. However, many of the negatives that previously created hesitancy have changed in recent years. Below, we have outlined a few of the most commonly mentioned negatives regarding the two leading alternative fuel vehicle types: Flex Fuel vehicles and Electric/Hybrid vehicles. Then, you can decide for yourself whether one of these vehicle types are practical for you! Cost – How much does the vehicle cost to purchase and operate? Flex Fuel: Flex Fuel vehicles typically cost about the same as a gasoline vehicle.1 For fuel cost, E85 typically costs slightly less than gasoline, however, due to decreased efficiency has a slightly higher cost per mile than gasoline.2 Overall, a Flex Fuel vehicle is likely to be slightly more expensive than a gasoline counterpart. Electric/Hybrid: This situation varies quite a bit depending on where you live. Electric vehicles and hybrid vehicles often cost considerably more than a conventional gasoline vehicle. For example, a plug-in hybrid will cost around $4000-$8000 more than a conventional model.3 However, there are federal rebates and local rebates that can refund thousands of dollars from the purchase price. Electric/Hybrid vehicles also tend to save money on fuel, with the possibility of saving thousands of dollars over the lifetime of the vehicle.4 Whether these rebates and fuel cost savings will eventually account for the higher purchase price can be estimated with comparison tools. -

Countries in the world are attempting to transition away from gasoline vehicles and to electric vehicles (EVs), in order to reduce emissions. However, there are several practical limitations with EVs, one of which is the “range anxiety” issue, due to the lack of charging infrastructure, the high cost of long-ranged EVs, and the limited range of affordable EVs. One potential solution to the range anxiety problem is the use of range extenders, to extend the driving range of EVs while optimizing the costs and performance of the vehicles. This paper provides a comprehensive review of different types of EV range extending technologies, including internal combustion engines, free-piston linear generators, fuel cells, micro Citation: Tran, M.-K.; Bhatti, A.; gas turbines, and zinc-air batteries, outlining their definitions, working mechanisms, and some recent Vrolyk, R.; Wong, D.; Panchal, S.; Fowler, M.; Fraser, R. -
