Toward Holistic Energy Management Strategies for Fuel Cell Hybrid Electric Vehicles in Heavy-Duty Applications

Abstract

The increasing need to slow down climate change for environmental protection demands further advancements toward regenerative energy and sustainable mobility. While individual mobility applications are assumed to be satisfied with improving battery electric vehicles (BEVs), the growing sector of freight transport and heavy-duty applications requires alternative solutions to meet the requirements of long ranges and high payloads. Fuel cell hybrid electric vehicles (FCHEVs) emerge as a capable technology for high-energy applications. This technology comprises a fuel cell system (FCS) for energy supply combined with buffering energy storages, such as batteries or ultracapacitors. In this article, recent successful developments regarding FCHEVs in various heavyduty applications are presented. Subsequently, an overview of the FCHEV drivetrain, its main components, and different topologies with an emphasis on heavy-duty trucks is given. In order to enable system layout optimization and energy management strategy (EMS) design, functionality and modeling

A Propulsion System Design Methodology Based on Overall Efficiency Optimization for Electrically Powered Vessels

“…This PS design methodology is based on a multivariable optimization process to maximize the overall efficiency of the system that propels electric boats. An exhaustive search optimization algorithm with a holistic approach is developed (Rudolf et al, 2021;Miranda et al, 2016), used to provide a solution by exploring all possible values for the design variables, having a fixed hull design, a set of electric motors, a set of available propellers and different cruise speeds established under the interest of developing boats operating in the area of interference of the ENERGETICA 2030 project.…”

Joint Component Sizing and Energy Management for Fuel Cell Hybrid Electric Trucks

“…Among all FC types, polymer electrolyte membrane FC (PEMFC) is proved to be commercially suitable for transportation and automotive applications, especially for passenger cars, buses, logistic vehicles, and trucks [2]. A PEMFC-powered truck, without any GHG emissions if green hydrogen is assumed, can achieve a comparable performance to a conventional internal combustion engine vehicle in terms of driving range and refueling time [3]. For example, the XCIENT Fuel Cell [4], with a travel range of about 400 km, can be charged within 8 to 20 min, depending on the ambient temperature and using a 350 bar tank with a capacity of 31 kg hydrogen.…”

“…In [29], integrated design and control optimization is performed for an FC powered mining truck to minimize lifecycle cost. In [3], powertrain topologies, layout optimization, energy management strategies, and co-design optimization are summarized and reviewed.…”

Optimal Hydrogen Production and High Efficient Output Smoothing in Wind Farm

“…Hydrogen is an essential energy source in many applications, such as fuel cell vehicles, hydrogen-powered heavy-duty trucks, household and industrial fuel cells (FCs) [1]- [3]. Moreover, valuable chemicals such as methane can be generated by blending hydrogen with carbon dioxide [4].…”
