emobilitytec magazine puts the SRe15 electric racing car under the magnifying glass

Since taking part in the Formula Student (2012) the Schanzer Racing Electric (SRE) team of the Technical University of Ingolstadt (THI) has been putting everything into electric power with their self-developed racing cars. With the SRe15 too, their current car, they are taking advantage of its energy recovery capacity and excellent torque curve. BFFT, since 2011 the main sponsor of the SRE-teams, is supporting the students both through a financial subsidy and by providing expertise, particularly in energy storage development and electrification.
In the current 4th 2015 issue of the journal emobilitytec, the battery design and construction of the SRe15 racing car now been examined and presented in more detail. Since at the THI there was neither the technical equipment, nor the students with the necessary qualifications to work with more than 60V, the battery assembly and approval inspections were carried out at the high-voltage workshop in BFFT’s headquarters in Ingolstadt/Gaimersheim in May 2015. Here the students were also able to customize the wiring harness of the battery and use a battery management system (BMS) that monitors the temperature and the individual cell voltages, as well as shutting off the battery in an emergency. This BMS monitors the whole battery and communicates via a bus system with the central control unit in the vehicle.
You can find further details about the construction of the battery and the other challenges the students had to overcome in designing of SRe15 in the emobilitytec article.
