Modeling of Electric Vehicle Chargers by its Characterization in Charging Stages

Assessing the impact on power quality due to electric vehicle charging implies to make of it a reliable process, including in the process the modeling of some basic elements involved in the process, such as the power grid, the charger and the battery. Each developed model must approach as close as possible to reality, including characteristic dynamics of those models. As such, this paper proposes a methodology for modeling electric vehicle chargers, where is also stated that the charger and the battery should be modeled always together, so that trough some simplifications, battery dynamism can be included, through its discretization over charging stages.
