Mô tả
This is a hands-on course, explaining step-by-step, with real applications, how to size/calculate the parameters of the high voltage battery and electric machine, based on performance requirements.
Starting with performance requirements: top speed, 0-100 kph acceleration time and maximum range, we will calculate the parameters of the battery pack and electric machine required to achieve the performance attributes.
The main components of the powertrain (high voltage battery, electric machine, transmission and DCDC converter) are explained, describing their main parameters and operating mode.
A brief description of the electric vehicle powertrain architectures is provided, explaining the main components, how they operate, and which are the advantages and disadvantages of each type.
Based on the vehicle's longitudinal dynamics, a drive cycle will be run in Scilab, which will provide the average energy consumption of the vehicle.
The parameters of the electric machine and high voltage battery will be calculated to meet the performance requirements of the electric vehicle.
A full electric vehicle dynamic model will be developed in Xcos and run through various cycles: top speed, hill climb and homologation drive cycle, to assess the performance of the powertrain against requirements.
A complete set of Scilab scripts will be developed for components sizing, data processing and data visualization.
A full tutorial will be provided on how to use the on-line (web based) simulation tool for electric vehicle powertrain design
