Development of electric vehicle architectures requires complex analysis and innovative
designs in order to produce a highly efficient mode of personal transportation acceptable
to the target demographic. Using computer-aided modeling and simulation has been
proven to decrease the development time of conventional vehicles while increasing overall
success of the product design. Computer-aided automotive development also allows a fast
response to the testing and inclusion of developing technologies in individual systems.
Therefore, it follows to use this technique in the research and development of electric
vehicles for consumer markets.
This paper presents a system level model development and simulation for an electric
vehicle using the Matlab-Simulink platform and its associated process. The current state
of the art technologies for electric and plug-in hybrid electric vehicles are given to provide
an introduction into the subject. Following, the project development is briefly described,
detailing the specific goals for the project and the methods by which results were achieved.
Next the paper discusses the analytical and simulation models for each key component as
divided by the following systems: battery, charging, and traction. Model assembly and the
development of a graphic user interface follows. Finally, the testing procedures for model
validation, along with results, and future project works are provided.
