Final Report TUfast Racing Team

We, the TUfast Racing Team, are a student association that develops, designs, and manufactures a new racing car every year for the electric and autonomous disciplines as part of the Formula Student project. In the past season, within eight months, we successfully completed our racing car named ‘xb023’ with a team of a total of 80 students from the Technical University of Munich and competed against other teams in competitions across Europe.

In summary, the past season was one with several highs and lows. We started in the Netherlands with a good 6th place, considering we had several minor issues. We then moved on to Austria, where we could demonstrate what our racing car is capable of and ended up in 2nd place, with a minimal distance to the first place. Four days later, we were already in Hungary, this time operating purely autonomously. The test days just before went very promisingly, but unfortunately, various problems occurred during the competition, resulting in us finishing in 8th place. A week later, the most important competition for us took place at the Hockenheimring. Unfortunately, luck was not always on our side during the competition, and due to several technical issues, we ended up in 14th place.

To ensure a high reliability of the vehicle, high-quality and high-precision printed circuit boards are required. Our partner EuroCircuits has been supporting us for several seasons now with printed circuit boards of outstanding quality, enabling us to continuously improve our electronic components. In the past season, EuroCircuits supported us by manufacturing our Battery Management System (BMS) for both the High-Voltage (HV) and Low-Voltage (LV) accumulators. Additionally, EuroCircuits provided the Power Distribution Unit (PDU) for our LV supply.

Our HV accumulator’s BMS consists of one master and a total of 16 slaves. The slaves are directly attached to the cell stacks and monitor the voltage and temperature of the battery cells. These are essential for the safety of the accumulator and thus the entire vehicle. Each slave communicates with the master, which processes the information and then sends it via CAN to other electronic components in the vehicle.

Without the support of EuroCircuits, the realization of such a complex project would not be possible! For this, we would like to sincerely thank EuroCircuits!
