The three wheeled vehicles are extremely popular in the Indian subcontinent and are constantly posting a positive growth in sales. Given this trend and their polluting nature they can be noted as sizeable contributors to the air quality issues plaguing the metropolitan cities. With the nation aiming at eradicating the use of internal combustion engines (ICE) in passenger transportation by the year 2030, there have been attempts to convert ICE three-wheelers to battery electric three-wheeler. However, the battery electric three-wheelers, which are quite commonly used for end-mile connectivity, serve to highlight the demerits of the technology pertaining to their range, charge cycle, power to weight ratio, and efficiency. Hydrogen based are fuel cells gaining traction as a potential alternative to batteries due to their efficient and clean power generation. The present paper aims to develop and recommend an optimized power management strategy along with a driveline model for addressing the intra-city connectivity in a typical Indian city. The simulation models considering a parallel hybrid electric three-wheeler with a Proton Exchange Membrane fuel cell as the…

An analysis of the Fuel Cell Pack with different Drive cycles Abstract: In the view of the Environmental friendly future, every automotive manufacturer is making a move towards electric mobility. Zero emission can be achieved with the help of electric vehicles. However, there are some limitations too. Battery electric vehicle (BEV) gives a limited range in the vehicles and even their market penetration is difficult because of their energy storage capability. A fuel cell unit can be added to the system, which increases the range and the energy capacity of the system. Hydrogen fuel cell electric vehicle (FCEV) system is faster to refill compared to plugin charging in the Battery electric vehicle (BEV). This study deals with the behavioural analysis of the Polymer Electrolyte Membrane (PEM) Fuel cell based on the different drive cycles. Fuel cell model has been developed and simulated in the SIMULINK environment. Simulation results were obtained for the different drive cycles. Fuel cell controls were even observed for the city start/stop cycle. The results obtained from the simulation for the different…

A novel approach on range prediction of a hydrogen fuel cell electric truck C.Venkatesh - Manager - Product Development, Sustainable Mobility & Advanced Technologies Abstract: A novel approach on range prediction of a hydrogen fuel cell electric vehicle Abstract: Today's growing commercial vehicle population creates a demand for fossil fuel surplus requirement and develops highly polluted urban cities in the world. Hence addressing both factors are very much essential. Battery electric vehicles are with limited vehicle range and higher charging time. So it is not suitable for the long-haul application. Hence the hydrogen fuel cell based electric vehicles are the future of the commercial electric vehicle to achieve long range, zero emission and alternate for reducing fossil fuels requirement. The hydrogen fuel-cell electric vehicle range, it means the total distance covered by the vehicle in a single filling of hydrogen into the onboard cylinders. And here the prediction of the driving range is essential based on optimal parameters (vehicle acceleration, speed, trip time etc.) before the start of the trip. If the driver starts the…

To be published on 2019-10-30 by SAE International in United States
Hydrogen fuel is rapidly emerging as a clean energy carrier solution that has the potential to decarbonize a variety of industries, including, or predominantly, the transportation industry. Fuel cell electric vehicles (FCEVs), which electrochemically combine stored hydrogen with atmospheric oxygen to efficiently generate electricity while producing only water vapor and small amounts of heat, are heralded to be a game-changing technology. The so-called hydrogen economy has a potential to displace traditional fossil fuel-based economy, with transportation industry being the first mover in the hydrogen space. Technological advances made in the last decade in the areas of hydrogen generation and fuel cell technology have enabled the current uptake of hydrogen-based solutions for vehicle applications. Driven by the technologically-enabled cost reduction, worsening climate changes, and often the presence of policy-mandated carbon tax mechanisms, hydrogen is becoming an automotive solution of choice for many governments, vehicle manufacturers, and customers. The major drawbacks of hydrogen compared to the other competing clean-energy technology like battery is the high cost of hydrogen refueling and FCEVs. However, application of the economy of…

The conventional energy sources are getting depleted while at the same time the energy demand keeps growing. Hence, it is important to consider non-conventional energy sources to meet future energy demands. The renewable energy based microgrid system is one of the promising solutions to meet this increasing energy demand. The major parameters under consideration in a micro-grid system are cost-effectiveness, quality of service and energy management. This work concentrates on the energy management of the Photovoltaic/Wind based microgrid system connected to the fuel cell, microturbine and battery under Islanding (or) Autonomous mode and Grid-Connected Mode. The current model of PV, Wind and Battery systems are employed. The Wind, PV and Battery types are chosen from i-HOGA. The optimal combination of these sources with the aim of minimizing the operating cost, pollutant treatment cost and maximizing reliability using both single and multi-objective particle swarm optimization (PSO) has been considered. This microgrid has also been analyzed under three different strategies for both grids connected and islanded mode and the best energy management strategy is obtained after analysis.…

Environmental and Health Impact of Electric and Hydrogen Light Vehicles: The Case of an Italian Small City

University of Roma Tor Vergata-Luca Andreassi, Giacomo Falcucci
University of Tuscia-Andrea Luigi Facci, Stefano Ubertini
Published 2019-10-07 by SAE International in United States
As the emission regulations get more and more stringent in the different fields of energy and environmental systems, the electric and fuel cell electric vehicles have attracted growing attention by automakers, governments, and customers. Research and development efforts have been focused on devising novel concepts, low-cost systems, and reliable electric/fuel cell powertrain. In fact, electric and fuel cell vehicles coupled with low-carbon electricity sources offer the potential for reducing greenhouse gas emissions and exposure to tailpipe emissions from personal transportation.In particular, Pedal Assisted Bicycles popularity is rising in urban areas due to their low energy consumption and environmental impact. In fact, when electrically moved, they are zero emission vehicles with very low noise emissions, as well. These positive characteristics could be even improved by coupling a PAB with a fuel cell based power generation system, thus increasing the vehicle autonomy without influencing their emissions and consumption performances.In this paper, four types of vehicles are compared from an environmental and accessibility point of view: conventional car, bus, electric PAB and hydrogen fuel cell PAB; for such…

Fuel Cell-Based Powertrain Analysis for Tramway Systems

Università della Calabria-Petronilla Fragiacomo, Francesco Piraino
Published 2019-10-07 by SAE International in United States
In this paper, a comparison of three different hybrid powertrains is analysed. The numerical model is used to simulate powertrain behaviour in rail application, on a pre-set drive cycle, composed of many acceleration and decelerations, in order to test the components features.The numerical model is dynamic and it is implemented in Matlab-Simulink environmental.A proton exchange membrane fuel cell (FC) is used; it is the most used in transport applications, thanks to its lower temperature compared to the other fuel cell types, which allows fast start up operation and rapid demand changes. A standard supercapacitor (SC), given by higher power density, is utilized as the energy storage system (ESS), Regarding the battery (B), two types are considered, because the battery is used both as prime mover and main component of the ESS; Li-ion batteries are chosen, owing to their good trade-off between specific power and energy.Therefore, three configurations, FC-SC, FC-B and B-SC, are analysed.The vehicle model takes into account other components. The regenerative brake system is used to recover energy during the deceleration phases, and the…

Simultaneous Optimization of Real-Time Control Strategies and Powertrain Design for Fuel Cell Hybrid Vehicles

University of Salerno, Italy-Marco Sorrentino, Dario Capaldo
Published 2019-09-09 by SAE International in United States
The successful introduction of low-carbon footprint and highly efficient fuel cell vehicles represents nowadays a key action to achieve sustainable mobility worldwide. The main technological barriers (i.e., market price, lifetime and performance) to be overcome justifies an increasing attention towards the development of mathematical tools featuring co-optimization capabilities, so as to adequately account for the strong interactions and mutual influence between design criteria and selected control strategies. This paper thus presents and discusses the integration of a comprehensive model of a generic FCHV architecture with a specifications independent control strategy within a modular constrained optimization algorithm, the latter conceived in such a way to simultaneously find the optimal FCHV powertrain design and real-time applicable control strategies. Suitable design and energy management criteria, accounting for also the impact of driving mission on proper management of available power sources, were selected. The proposed co-optimization procedure aims at determining the main powertrain design parameters (i.e., nominal fuel cell system power and battery pack energy density), as well as some key driving cycle-related information (i.e., power prediction time horizon),…

A Practical Recuperated Split Cycle Engine for Low Emissions and High Efficiency

Dolphin N2 Ltd-Nicholas Owen, Fabrizio Treccarichi
Hiflux Limited-David Barnes, Tanzi Besant
Published 2019-09-09 by SAE International in United States
The Recuperated Split Cycle Engine is a new type of ICE, offering a step change in efficiency and tailpipe emissions. It targets the heavy duty, long-haul sector (trucks, off-highway, rail, shipping), where electrification is most challenging, and distributed generation, where capacity is required to support rising electrification. The engine separates cold (induction, compression) and hot (combustion, expansion) parts of the cycle; waste exhaust heat is recovered between them via a recuperator, as in a recuperated gas turbine. Recent research presented at this conference [1] shows that the sonic airflows seen in the induction event give rise to extraordinary fuel mixing and clean, cool combustion, with potential for after-treated emission levels between SULEV and zero-impact (either unmeasurable or below ambient). Recuperation and thermal insulation of the hot cylinder (both feasible within the capability of common materials) also enable high thermal efficiency, with a flatter efficiency map than a conventional ICE. Combining the two attributes, and introducing sustainable fuels, places this readily manufactured, affordable technology on a par with battery-electric and fuel cell propulsion. Results from simulation…
