Team Profile:

This is Revolve NTNUs fourth car in the teams brief history and the second electric. The car has been designed and built by 50 dedicated students who has put in over 60000 hours over the last year to complete the car in only eight months. The car is almost completely redesigned from last year with new and improved solutions.

Weight reduction has been a focus while still being within the rule changes for the upcoming season. The cars carbon fiber monocoque, rims, driveshaft, steering system and wing package makes it possible to produce such a low weight car.

To keep the weight down while still meeting the energy demands we have chosen to use battery cells with a very high energy density of 192 Wh/kg and total energy of 7.45 kWh.

The team has an all self-developed electronics system, and has taken the leap to design and manufacture our in-house battery management system and inverter for the first time. This gives us the possibility to design it specifically for our needs while also reducing the weight even further.
