An electric vehicle is a complex system where multipleconverters are connected to a common DC-bus. In order todetermine the current and voltage harmonics on the DC-bus, allingoing components and subsystems needs to be modeled on adetailed level. In this paper, the focus lies on cable modelingwhere a high frequency cable model is incorporated in a drivesystem model. The resulting current and voltage ripple in thesystem is then compared to measurements in an experimentalsetup. Due to the improved cable model and an extensive systemparameter identification procedure, the usage of the systemmodel was found valid for harmonic frequencies up to 1 MHz.The main harmonic component at 20 kHz was simulated with~1.7 % accuracy and the components in the range 35 kHz to200 kHz with <6 % accuracy compared to measurements.
