Abstract

Fast charging station caters to the need for high power requirement for electric vehicles (EVs) charging in a short duration. Integration of local distributed generation resources can reduce the impact of the fast charging station on the grid. However, the intermittency of the distributed generation calls in for energy management system. This paper envisages the development of a rule based-modal control design for the energy management system (EMS) of a multi charger level 3 (50 kW) DC fast charging station (FCS). The paper presents the offline and controller hardware in the loop (CHIL) validation of the implemented design. Finally, three scenarios with respect to available grid energy are explored including the study of power sizing of ESU in order to provide a system level optimization for the performance of the EMS.
