The comparative study of drivetrain of high-performance electric vehicle

When constructing the electric vehicle for the Shell Eco-marathon competition in Urban Concept category, the Smart Power Team had to face the problem of choosing the perfect drivetrain. For this purpose, two bests concepts were studied. The first concept assumed the use of high-speed BLDC motor along with belt transmission with toothed belt. The second concept assumed the low-speed BLDC hub motor. The research was conducted for the MuSHELLka vehicle on the roller dynamometer. The aim of the research was to compare both concepts. The main selection criterion was the performance of both systems, measured at constant load and speed range of 0-30 km/h. The measurements were carried using the National Instruments hardware and software devices, the analysis of the results was performed in MATLAB software. This article includes the accurate description of the measuring circuit, the course of the research, data analysis and conclusions.
