eSleek from DHBW Engineering optimized with HV Breakout Modules

CSM and Vector Informatik support Formula Student with E-Mobility Measurement System.

The team DHBW Engineering from the Baden-Wuerttemberg Cooperative State University (DHBW) Stuttgart has been participating in the international engineering competition "Formula Student" for years with an electric racing car and for the first time also with an autonomously driving racing car.

Of course, this is not the first season that an eSleek (electric racing car) from DHBW Engineering has been at the front of the pack in Formula Student. But this year offers special challenges: On the one hand, the special circumstances of the last 12 months, which made the development work more difficult. On the other hand, the team set itself the task of developing its own power electronics and testing them on a new test bench.

CSM and Vector Informatik were able to support the team in this development: A complete E-Mobility Measurement System was installed to analyse inverters, electric motors and other powertrain components.

HV Breakout Modules were used on the test bench to measure current and voltage at the input (DC) and in the three (AC) phases at the output of the inverter.

The Vector eMobilityAnalyzer was then used to perform the required efficiency and power calculations with the acquired measured values.

As the first race event of the 2021 season showed, the efforts are paying off: The DHBW Stuttgart team won a second place in the "Efficiency" discipline and ended up in third place overall.

We wish them success for the remaining races of the season and look forward to continuing to support the DHBW team.
