<p dir="ltr">The automotive industry has witnessed a significant transformation in recent years, largely
driven by the emergence of electric powertrains. These systems offer a cleaner and more efficient
alternative to traditional internal combustion engines, marking a pivotal shift towards
sustainability in the transportation sector. At the heart of electric vehicles (EVs) lies the powertrain,
a complex assembly of components tasked with converting electrical energy into mechanical
power to propel the vehicle. In the context of electric race cars, the design and optimization of the
powertrain are of utmost importance to achieve high performance on the track. The powertrain
typically consists of four major components: the motor, inverter, battery, and gearbox. Each of
these components plays a critical role in ensuring the efficient conversion and utilization of
electrical energy to drive the vehicle forward. The process of designing an electric race car
powertrain begins with a thorough understanding and explanation of each component's function
and contribution to overall performance. This foundational understanding serves as the basis for
subsequent analysis and optimization efforts. Central to the design process is the selection and
configuration of the motor and battery, two key components that heavily influence the vehicle's
performance characteristics. To facilitate this decision-making process, engineers leverage
specialized software tools such as OptimumLap, MATLAB, and Simulink. OptimumLap allows
engineers to input relevant parameters of the race car, such as its drag coefficient and frontal area,
to gain insights into its aerodynamic performance. By conducting simulations on specific race
tracks, such as the Adelaide circuit, engineers can generate valuable data representing the vehicle's
performance in terms of lap times and speed. MATLAB's Grabit tool is then utilized to extract
velocity data from the simulation results, providing crucial input for further analysis. This data is
used to create a comprehensive table of values representing the vehicle's velocity profile under
different conditions.
Finally, engineers develop a Simulink model to simulate the operation of the electric
powertrain under various scenarios. This model allows for the extraction of critical performance
metrics and parameters, enabling engineers to optimize the motor and battery configuration to meet
the specific requirements and constraints of the race car.</p>
