An electric vehicle is a complex system where multiple converters are connected to a common DC-bus. In order to determine the current and voltage harmonics on the DC-bus, all ingoing components and subsystems needs to be modeled on a detailed level. In this paper, the focus lies on cable modeling where a high frequency cable model is incorporated in a drive system model. The resulting current and voltage ripple in the system is then compared to measurements in an experimental setup. Due to the improved cable model and an extensive system parameter identification procedure, the usage of the system model was found valid for harmonic frequencies up to 1MHz. The main harmonic component at 20kHz was simulated with~1.7% accuracy and the components in the range 35kHz to 200kHz with $<6$% accuracy compared to measurements.
