Abstract: The application of motor and converter in a hybrid vehicle can lead to a significant increase in electromagnetic compatibility. The influence of traction batteries as part of the electromagnetic interference path was not well considered. In this paper, high-frequency circuit models of single cell, cells connected in series and cells connected in parallel were proposed and developed based on their impedance characteristics and their structure features. Finally, values calculated based on the models and data measured actually were compared and analysed. The results allow the prediction of high frequency losses and the simulation of batteries as interference path.

Keywords: hybrid electric vehicles; high-frequency modelling; hybrid vehicles; vehicle batteries; electromagnetic compatibility; EMC; impedance; traction batteries; simulation; interference path.
