| Abstract | The electrics vehicle (EV) fast charger for smart city application is an evolution era in upcoming days. This paper reviews the current status and implementation of different fast charging topologies, charger power level and infrastructure for EV in smart city application. The charging systems for EV are categorized into off-board and on-board types with unidirectional or bidirectional power flow capability. The unidirectional charger limits hardware requirements and simplifies interconnection issues and bidirectional charging supports battery energy injection back to the grid. An on-board charger limit power level because of weight, size and cost constraints. They can be integrated with the electric drive to avoid these problems and the availability of charging infrastructure. An off-board charger are designed for fast charging and are less forced by size and weight. In this work, various charging typologies and scheme for fast charger is presented and discussed in brief. Also, few power electronics circuit configurations for fast charger are discussed. |
