A test bench for hybrid propulsion train research and development

This paper presents a versatile laboratory test bench built up for carrying out researches and experimental tests about hybrid propulsion trains, without the availability of a real vehicle and an automotive test track. The test bench is realized by using a relatively low-power engine that can be combined with one or more electrical machines for emulating different hybrid architectures. In addition to the test bench structure, some examples of usage are also described in the paper.
