Investigation of the revision requirement of an existing electrical installation integrated with electric vehicle charging station in Simaris software

Abstract

In recent years, electric vehicles have come to the forefront with decreases in fossil fuel sources, fluctuations in fossil fuel prices, and advances in battery technologies and energy management systems. Today, in many developed countries of the world, both the production of electric vehicles and the production and installation of charging stations to meet the energy needs of these vehicles are being carried out. Along with the installation of electric vehicle charging stations, their impact on the electrical installation in which such systems are integrated has also become important. With the integration of electric vehicle charging stations into the existing electrical installations, on the related installations; The need arises to reconsider voltage drop, current carrying capacity of cables, short-circuit breaking capacity of switchgear equipment, selectivity, and similar electrical phenomenon. In this study, the revision needs of the electrical installation that can be realized in case of the integration of electric vehicle charging station to a sample installation are examined together with the simulation results in Simaris. The review focused on the switchgear equipment and wiring revision needs that may arise in an existing installation with an electric vehicle charging station integrated. In this context; voltage drop, current carrying capacity, switchgear change, short-circuit current, and selectivity concepts are emphasized. Finally; together with the simulation results, the necessity of changing electrical equipment in an installation where the electric vehicle charging station is integrated, in order to ensure healthy and safe operating conditions, is revealed.
