A Framework for Electric Vehicle Development: From Modelling to Engineering Through Real-World Data Analysis

The Project ASTERICS, an international EU-STREP Project with 10 partners from 7 countries, follows the target to increase the efficiency of fully electric vehicles (FEV) by means of improved virtual models and intelligent testing and verification methods. Better models in the early design- and development phases allow more realistic and improved concept studies and hence detailed optimization at component level as well as global optimization at system level. Through intelligent testing methods it will be possible to enhance the model quality on one hand and reduce the test time on the other hand. These testing methods shall also allow the assessment of durability and ageing effects for electrical components in the FEV-driveline. The combination of virtual simulation with realistic, for FEV relevant driving cycles leads to a very good possibility for optimization of predictable mileage. In this paper the results of the first phase of the ASTERICS project are presented. It describes the modelling approach and gives a good overview on virtual product development by means of model based system engineering (MBSE). Also described is the methodology to identify design goals based on real life data through assessment and definition of a representative driving cycle for FEV.
