Component-based modelling of EV battery chargers

This paper reviews typical circuit topologies and control algorithms for on-board unidirectional single-phase electric vehicle battery chargers (EVBCs) and provides simple yet reasonably accurate component-based models for their representation for power system analysis. The accuracy of the developed models is validated against measurements of actual EVBCs, for both ideal voltage supply conditions and typically distorted voltage supply waveforms. The paper also provides exponential and polynomial EVBC model interpretations, as well as some discussion of the further use of the presented models for the analysis of existing networks and future smart grids with high penetration levels of EVBCs.
