Formula Group T is a project run by Belgian masters students in engineering from GROUP T. They design and build small electric vehicles and compete with other universities worldwide in the Formula Student competitions during the summer.

Design 1: Areion

Areion was their first car and was built in 2011-2012. One of the key technologies Formula Group T implemented in Areion was additive manufacturing techniques, which can be found in the production of the uprights of the suspension system. Stereolithography techniques were used in the production and development of the body enclosure.

Design 2: Eve

In 2013, Formula Group T finished their second car, Eve. Like her predecessor, Eve is a pioneer, a platform for companies to demonstrate existing core technologies or to test new technologies. For instance, Eve’s electrical drivetrain assembly starts with a 360 Lithium-ion cell accumulator at a voltage of 444V. The accumulator has a carbon fibre fire resistant enclosure and is divided into 10 modules. The accumulator empowers the self assembled motor drive. This lightweight drive controls our 2 motors and weighs less than 15 kg

Eve_busbarsWith the help of Rogers Corporation, Formula Group T was able to make the battery pack by connecting the cells and cell stacks through the use of busbars. Also, the circuit to switch the motor between Δ and Y was made with RO-LINX® busbar technology. Finally, to make fireproof barriers between cell stacks and to damp for vibrations, BISCO® silicone was used.

In addition, Group T used power modules from one of the Rogers PES Division’s key customers, which contain curamik® substrates and BISCO® silicones.

A lot of Rogers in a small car! PES presented Eve at the 2013 PCIM Europe and caught the attention of many attendees.

Design 3: June

Formula Group T has finished and raced their 3rd car, June. June features a monocoque design, a sandwich structure made out of carbon fibers and a foam core. The goal of a monocoque is to transmit the forces through the skins, this gives a better force distribution and provides a lighter chassis.

Best of luck in with the 4th generation car, which will launch shortly!
