Abstract
This thesis focuses on the optimization of a dual-motor powertrain for an electric
vehicle known as the LEVKART, a lightweight four-wheeled vehicle developed
for both indoor and outdoor usage. The study examined the effect of different
battery voltages, specifically 36 V, 39.6 V, and 43.2 V, on the vehicle’s performance. The main focus lies on reducing the energy consumption and increasing
the range while adhering to some specific vehicle constraints.

To simulate the vehicle’s behavior, a dynamic MATLAB/Simulink simulation
model was used. This model was based on an existing one that was modified to
better suit the characteristics of the LEVKART. The model incorporated real-world
data obtained from motor testing to ensure that the... (More)

To simulate the vehicle’s behavior, a dynamic MATLAB/Simulink simulation
model was used. This model was based on an existing one that was modified to
better suit the characteristics of the LEVKART. The model incorporated real-world
data obtained from motor testing to ensure that the simulations were as
realistic as possible. The model was used to simulate various drive cycles and
assess the vehicle’s behavior during different operational scenarios.

The results from this study provided an initial suggestion for optimizing the
powertrain, specifically regarding the most suitable battery voltage for the current electric machine and power electronic components under the specified operating conditions. However, these findings should be interpreted cautiously, as
the simulation model would benefit from further work before being fully reliable. (Less)
