Optimization of busbar systems at electric vehicle charging stations

In this study, the busbar system and plug-in tap off box of electric vehicle charging stations, which are modular, easy to install and operate, can be maintained without cutting off the energy of other lines and will cause much less energy loss compared to existing wired solutions, are discussed. The advantages of a system designed with a busbar plug-in tap off box are used to evaluate its performance in terms of energy efficiency. While installing this system, the equipment that should be used for user, vehicle and system safety is included. The standards that should be followed when installing an electric vehicle charging system are examined in detail. In the light of this information, a new tap off box design was made for the busbar system. UL and IEC standards were taken into consideration in the design of the box. The box interior design was made and its prototype was produced. Then, the first priority was to plan and perform tests under IEC laboratory conditions for commercialization in Turkey and Europe. Experimental verification of the equipment used was carried out with the tests performed. The designed box is a box that is protected against stray currents, will not be affected by lightning strikes, will not pass excessive current, can communicate with the vehicle and with each other if desired, can be opened only by the user with the recognition equipment placed and how much power is used can be calculated with the reading devices on it. The plug-in outlet box busbar system proposed in this study and the electric vehicle charging station designed for twelve vehicles as a model offer a highly energy efficient, safe and sustainable alternative for infrastructures. It is evaluated that it can work in harmony with integrated applications to city networks and modular energy management systems.
