Abstract: A continuing global demand for lower emissions and improved power train efficiencies is likely to increase the production rate of electric vehicles in the near future. Modelling, simulating and optimising components used in electric vehicles affect and improve important parameters, such as efficiency, drivability and safety of vehicles. This paper presents a co-simulation platform for an electric vehicle. Upon this platform, high-resolution, complex thermal and dynamic mathematical models for each component are introduced. Attention was paid to the auxiliary loads, which have a large impact on the drive range, but had been widely neglected in earlier electric vehicle modelling works. The models are connected via a co-simulation software tool. Validating the models using previous vehicle measurements is followed by an assessment of thermal management techniques. In addition, an approach of how to analyse and evaluate vehicle thermal and energy management techniques and their combination with different driving conditions in a co-simulation environment is suggested.

Keywords: thermal management; energy management; electric vehicles; electric components; co-simulation; simulation; vehicle modelling; mathematical modelling; auxiliary loads; driving conditions.
