Recent environmental and climate change issues make it imperative to persistently approach research into the development of technologies designed to ensure the sustainability of global mobility. At the European Union level, the transport sector is responsible for approximately 28% of greenhouse gas emissions, and 84% of them are associated with road transport. One of the most effective ways to enhance the de-carbonization process of the transport sector is through the promotion of electric propulsion, which involves overcoming barriers related to reduced driving autonomy and the long time required to recharge the batteries. This paper develops and implements a method meant to increase the autonomy and reduce the battery charging time of an electric car to comparable levels of an internal combustion engine vehicle. By doing so, the cost of such vehicles is the only remaining significant barrier in the way of a mass spread of electric propulsion. The chosen method is to hybridize the electric powertrain by using an additional source of fuel; hydrogen gas stored in pressurized cylinders is converted, in situ, into electrical energy by means of a proton exchange membrane fuel cell. The power generated on board can then be used, under the command of a dedicated management system, for battery charging, leading to an increase in the vehicle's autonomy. Modeling and simulation results served to easily adjust the size of the fuel cell hybrid electric powertrain. After optimization, an actual fuel cell was built and implemented on a vehicle that used the body of a Jeep Wrangler, from which the thermal engine, associated subassemblies, and gearbox were removed. Once completed, the vehicle was tested in traffic conditions and its functional performance was established.

“…Roberto Álvarez Fernández et al studied mileage and energy consumption of EVs under various energy management strategies. The authors believed that before enough infrastructure was provided, a combination of two power modes (hydrogen and electric energy) could be an effective method to power vehicles with low risk [21]. Z. Mokrani et al studied the fuel cell/accumulator power systems used in PHEVs and verified the effectiveness of the EV energy management and control strategy they came up with via a hybrid system simulation model based on Matlab/Simulink [22].…”

Electric vehicles (EVs) include battery electric vehicles (BEVs), fuel-cell vehicles (FCVs) and fuel-cell hybrid electric vehicles (FCHEVs). The performance of vehicles is usually evaluated using standardized driving cycle tests; however, the results from standardized driving cycle tests deviate from the real-world driving cycle. In order to test the adaptability of EVs to real-world driving cycles, conditions of three typical routes in Tianjin are collected and their characteristics analyzed; then BEV and FCV models are created based on a type of FCHEV to simulate 0–100 km/h acceleration and cruising performance under a real-world driving cycle; finally, a motor bench is used to test the performance of FCHEV under the NEDC (New European Driving Cycle). After the adaptability of the three models to real-world driving cycle is compared based on the simulation and test results, it is found that FCHEV can recycle braking energy and has quick dynamic response, which can be well adapted to the real-world driving cycle.

“…These solutions include, inter alia, the installation of power lines for the vehicle, installed over the road on which it moves [5] or the construction of a road covered with photovoltaic panels with devices for wireless transmission of energy directly to the vehicle [6,7]. Another solution to augment an electric propulsion system is to support it with a combustion engine [8][9][10], micro gas turbine [11][12][13], fuel cells [14][15][16][17][18][19][20], supercapacitors [21], or various types of batteries with the possibility of their charging while driving [22][23][24][25][26]. Hybrid vehicles can be divided according to the type of the drive system, i.e.…”

Streszczenie. W publikacji przedstawiono wyniki analiz dotyczących zastosowania spalinowych zespołów prądotwórczych małej mocy wykorzystywanych do zwiększania zasięgu pojazdów z napędem elektrycznym. Spalinowe zespoły prądotwórcze stanowią rozwiązanie podstawowych wad pojazdów elektrycznych, takich jak ich krótki zasięg, wynikający z ograniczonej pojemności akumulatorów i długiego czasu ich ładowania. Stosuje się je głównie do przejazdów na długich dystansach pomiędzy miastami. W pracy omówiono podstawowe konfiguracje układów napędowych stosowanych w pojazdach elektrycznych i hybrydowych, oraz zaprezentowano podstawowe konfiguracje układów napędowych wykorzystujących spalinowe zespoły prądotwórcze do zwiększania zasięgu pojazdów z napędem elektrycznym. Na podstawie testów trakcyjnych zrealizowanych w rzeczywistych warunkach drogowych dla samochodu elektrycznego wspomaganego pracą spalinowych zespołów prądotwórczych (4 kW benzyna, 5,5 kW diesel) zainstalowanych na lekkiej przyczepie, opracowano model matematyczny układu w środowisku Modelica. Opracowany model matematyczny uwzględnia obciążenia dynamiczne działające na zespół pojazdów w ruchu wraz z elektrycznym układem napędowym wspomaganym przez spalinowy zespół prądotwórczy. Przedstawiono wyniki badań symulacyjnych dla wybranych profili trasy i prędkości jazdy. Przeprowadzono badania dla wybranych wartości współczynników stanu naładowania akumulatorów SOC ON-OFF (ang. State Of Charge), mających kilkuprocentowy wpływ na zmniejszenie zużycia paliwa i emisji szkodliwych gazów do atmosfery przez silniki spalinowe zespołów prądotwórczych.
