Feeling confident after creating two combustion cars, Revolve NTNU chose to delve into unchartered territory, by making its first electric vehicle. This was a huge challenge, as it adds a great deal of complexity. In turn, the petrol engine was replaced by a high voltage battery, printed circuit boards and electrical wiring.
Through three static events we must present the engineering design, cost considerations in addition to performing a pitch to judges acting as investors.
In the design event we demonstrate, show simulations and use theory to display the development process and engineering approach and results. The event is judged based on the engineering quality of the car and the processes executed to end at the specific solutions.
In the Cost Event we demonstrate cost trade offs done in the development of the car in addition to present an extensive cost report, which estimates production cost of the car.
The sales pitch motivates us to think of the cars attractiveness and market potential, investment key factors and how to present an investment opportunity to external investors.
Out on the track we must demonstrate in a number of performance tests how well our self-built race cars fare in its true environment.
In the Skid Pad Event the car’s ability to generate lateral acceleration is measured on a figure of 8 track.
In the Acceleration Event the car’s acceleration abilities is put to the test over a distance of 75 meters.
In the Autocross Event the on track performance is put to the test on a course of a kilometer with straights and curves. The lap time indicates the driving dynamics and handling qualities of the car.
The Endurance Event is raced on roughly the same track as in autocross, but over a distance of 22 kilometers. The car has to prove its acceleration, speed, handling, dynamics, fuel economy and reliability. The event is the ultimate test of the overall performance of the car.Energy usage is measured during the Endurance Event and is also a considerable factor in the competition. Energy efficiency is derived from lap times and the actual energy usage measured by a energy meter mounted in the tractive system of the car.
