The Formula Student competition series is a car and engineering competition where students from higher education can scale up their skills with designing and building a hobby race car and managing its financial background. Students from BME university formed a team called BME Formula Racing Team (FRT) to take part in this competition. The team achieved great results ever since its founding in 2008.

Nowadays aside from the combustion engine cars the ones with hybrid or electric drives are becoming more and more popular. In accordance with the latest trends there is also a category for electric cars in the formula student series.

The purpose of my project to design a unit in the electrical system of the BME Formula Racing Team’s electric race car built for the 2017 Formula Student season.

In the first part of the project I introduce the Formula Student series, BME FRT and the concept of the FREC-007 car emphasising the electronic system which I am actively developing with the team.

The second part of my project is about the design of the CAN Node board. In this part I describe the theoretical background of CAN communication that is widely used in the vehicle industry, I go into details why it became important to design a CAN Node. I also describe the design philosophy used in the Electronics group and show the steps during the design of the board. I also performed some measurements checking the functions of the hardware.

I end the project with the conclusions and the description of the further developments.
