Design, Analysis, and Optimization of a Multi-Speed Powertrain for Class-7 Electric Trucks

The development, analysis, and optimization of battery electric class-7 heavy-duty trucks equipped with multi-speed transmissions are discussed in this paper. The designs of five new traction motors-fractional-slot, concentrated winding machines-are proposed for use in heavy-duty electric trucks. The procedure for gear-ratio range selection is outlined and ranges of gear ratios for three-to six-speed transmission powertrains are calculated for each of the proposed electric traction motors. The simulation and gear-ratio optimization tasks for class-7 battery electric trucks are formulated. The energy consumption of the e-truck with the twenty possible powertrain combinations is mini-mized over the four driving cycles and the most efficient powertrain layouts that meet the performance criteria are recommended.

期刊介绍： The SAE International Journal of Alternative Powertrains provides a forum for peer-reviewed scholarly publication of original research and review papers that address challenges and present opportunities in alternative and electric powertrains and propulsion technology. The Journal strives to facilitate discussion between researchers, engineers, academic faculty and students, and industry practitioners working with systems as well as components, and the technological aspects and functions of powertrains and propulsion systems alternative to the traditional combination of internal combustion engine and mechanical transmission. The editorial scope of the Journal includes all technical aspects of alternative propulsion technologies, including, but not limited to, electric drives and electromobility systems, hybrid technology, battery and super-capacitor technology, power electronics, hydraulic drives, energy storage systems for automotive applications, fuel cell technology, and charging and smart grid infrastructures.
