The growing concerns regarding climate change and the environmental impact of using fossil fuels as the primary source for propulsion systems have led to a transition toward more sustainable propulsion systems. Technological advancements, customer preference changes, and policies have favored this transition in the past decades. Sustainable sources like batteries and fuel cells have introduced alternative solutions for replacing the ICEs. The Utilization of EVs in the transport sector offers lower GHG emissions and can reduce the dependence on finite fossil fuels. In this thesis, a MATLAB/Simulink-based model of a Fuel Cell Electric Vehicle (FCEV) powertrain for a cargo bike has been developed to simulate the powertrain’s dynamic behavior across various driving cycles.
