Electric hybridization kit for modification of a manual transmission motorcycle

Abstract

Design and implementation processes of a functional model of an electric hybridization kit for modification of a manual transmission motorcycle are presented in this paper. Considering the complexity of the development and the need to integrate different disciplines of engineering and design, the design process follows the VDI Guideline 2206 and proposes the use of the V-model. Requirements stated by a multidisciplinary group of engineers and potential users are presented as the starting point of the design methodology, followed by a conceptual design phase, and a detail design process according to three specific domains: mechanical engineering, electronic engineering and information technology. In order to achieve fuel economy and fewer emissions, a control with three different driving modes [Internal Combustion Engine (ICE) mode, Hybrid Mode and Regenerative Mode] is proposed including an intelligent switch between a 125 c.c ICE system and a 1000 W BLDC electric motor. Finally, a functional model of the modification kit is assembled on the motorcycle and its functionality is verified. The results show a considerable decrease in the use of the ICE, identifying the electric modification kit as a viable solution for the environmental problem generated by the motorcycles segment.
