Abstract
Hybrid Vehicles, Battery Electric Vehicles and Fuel Cell electric vehicles usually use asynchronous 3 phase AC electric motors or synchronous 3 phase electric motor with permanent magnets. These drive systems are commonly used and there is plenty of books and articles in this subject. My aim was to collect the possible solutions for a race car and set up a method to evaluate the different components. The high number of solutions was really confusing and even the similar parts have different characteristics, what we had to take into account.
Evaluation of the different traction systems can be hard and needs a lot of time. The effective and fast handling of the many parameters of the components is really an interesting task and that is, why I wanted to make whole system during my work. In this way, we can easily redesign our electric race car, when a supplier changes the properties of the part. We can check the new part functionality as well or we can change the whole system setup. Also the finetuning of the components can be made in this way. Parts of solar cars, fuel cell electric cars and hybrid cars can be selected with this presented method. I used Matlab/Simulink with Simscape and SimPowersystems modules to make appropriate models for each part of different systems. I made several assumptions during the task, in this way I could save a lot of computing time. This was crucial, because within 1 test case I called many times the model.
My aim was during this work to make a whole system of simulink models and make Graphical User Interfaces to make the setup of the model parameters easier. I also programmed different test cases to examine each part. Programming these GUi-s take quite much time but with this method we can save much more. Anybody can perform analysis, not only the person, who made the simulink model. We will be able to work effectively in team, because team members only need to fill out the input parameters GUI and check the results. I also made global test cases, where I tested the whole system. We can check the best setup from the resulting matrix. After validation we can build the car. Hopefully all of this work will be useful for the manufacturing of our new race car.
