Modeling of fast dc charger for electric vehicles and integration to grid

Energy consumption is increasing gradually with worldwide industrialization. The increase in consumption of energy creates a big amount of demand for production which is supplied by fossil fuels. The consumption of fossil fuels leads to environmental pollution. Additionally, limited petroleum reserves are remained. There is an enormous amount of fossil fuel consumption by internal combustion vehicles that are the most widely used vehicles worldwide. In addition to this, electric vehicles are clean, silent and simple to operate. Because of these reasons, the demand for electric vehicles is increasing. In this thesis, charger circuit for electric vehicles and its integration to grid are studied. In the study, significant charger modeling topologies in the literature are investigated. Advantages and disadvantages of these topologies are discussed. Among these topologies, one of the most common (constant current-constant voltage) topology is used. The best advantage of the studied topology is recharging the battery in the most appropriate manner. Data of Çukurova University's infrastructure is used for the system. Additionally, in the study we will examine the current drawn by the system, whether the infrastructure is adequate or not. If the results of the examination are found to be inadequate, then we should determine where new infrastructure systems will be needed. Also, the performance of charging station and grid for different cases are analyzed; response of multiple synchronous charging is also investigated.
