Design and Experimental Validation of a Scaled Test Bench for the Emulation of a Hybrid Fuel Cell Powertrain for Agricultural Tractors

Hybrid fuel cell powertrains are a promising strategy to reduce the environmental impact of vehicles and non-road mobile machinery. To preserve state-of-health cells, an energy storage system with sufficient power capacity, such as ultra-capacitors or batteries, should be introduced in help during sudden abrupt changes demands. However, presence two more sources necessitates development management strategy. The properly split request between different sources. In this paper, design experimental validation scaled test bench for emulation cell/battery powertrain vehicular application is presented. emulated through analogically controlled DC source that reproduces its real voltage–current curve. DC-DC used simple based on proportional-integral controller developed. external load reproduced using unit composed programmable electronic supply. Experimental tests performed evaluate behaviour characterize main components. results show successfully emulates accordance proposed
