Impact of 48V E/E systems in Hybrid Racing Cars

In this work, the possible benefits and drawbacks of 48 Volt E/E systems in MotorSport will be analyzed. MotorSport has always been a lauchpad for new technologies, and in recent years the necessity to increase the electrical power on cars has become a key study topic. Increasing the voltage level is one possible solution to mitigate the downsides of increased power. In this dissertation the technologies currently available on the market will be analyzed, with a focus on 48 Volt systems that are already deployed on hybrid vehicles. Subsequently, a real racing car E/E architecture will be analyzed and the impact of an installation of a 48 Volt system will be evaluated. There follows a discussion on vehicle power supply technologies that are already available and the challenges of the supply systems for the future, ending with a set of simulations and considerations about the power supply system of the car under evaluation.
