Team Profile
UoP Racing is the Formula Student team of University of Patras, Greece. The Class 2 team formed within UoP Racing, consists of new team members which design and develop the next UoP racecar, UoP5e. Evolving from this year’s car, UoP5e takes the next step by incorporating twin AC motors which will allow the team to fully exploit the benefits of electric drive by using torque vectoring in order to aid yaw acceleration and transient stability. Torque is transmitted through a self-designed two-stage gearbox to 10″ rear wheels. A simulation-based sensitivity analysis highlighted the areas that would render the biggest laptime improvements, namely aerodynamics and low center of gravity. Thus, the team moved the batteries on both sides of the chassis, significally lowering the CG. A self-developed distributed BMS continuously monitors the accumulator temperature and voltage, which was raised to 600V to reduce resistive losses and increase efficiency. Improved manufacturing techniques and layup, as well as a careful redesign allow for about 20% lower chassis weight, while maintaining the same torsional stiffness. Suspension maintains the same philosophy, with kinematics refined for the lower CG. On aerodynamics, the team aims to further develop the wing concept as well as incorporating undertray to the chassis, to further increase downforce.
Finally, we would like to thank the University of Patras and especially the Laboratory for Manufacturing Systems & Automation, as well as our sponsors and families for their support!
