Elektrikli bir araç için yüksek verimli güç aktarma organlarının tasarım ve imalatı

As a result of increasing environmental pollution and inefficient use of resources, global warming is among the most serious problems today. Studies carried out to solve this situation envisage the use of alternative propulsion systems and energy sources in vehicles. In this context, the main goal of this project is the conceptual design, manufacturing and testing of devices called electric motor, charging unit, battery pack and battery management system, which are the four main parts of an electric vehicle. An efficiency target at the IE4 level was determined in the conceptual design of the devices within the system, and the minimum conversion efficiency was determined as 90% according to this standard. While a brushless permanent magnet synchronous motor model was preferred in the motor design, a forward power design with two switches in the charging unit topology was preferred. Battery management system and packaging issues were studied together. In this way, cell voltages, temperatures, cooling method and current protection methods were studied in an integrated manner. The conceptual design and production of the products within the project have been completed and the relevant tests have been carried out. There are generally two methods of engine design in the literature. These are analytical and numerical approaches, and when the necessary processes are followed, the outputs of both methods should be the same. Therefore, both methods were used in this design study. Excel software was used for analytical calculations, and Ansys Rmxprt and 2D Maxwell software was used for numerical calculations.
