Abstract:

The core of this thesis concerns modelling, simulation and the study of the energy management system of an electric vehicle powertrain. More specifically this vehicle is a quadricycle L7e, whose name is Microlino 2.0. Thesis work is made in collaboration with Bylogix srl, a company near Turin operating as a tier 1 in automotive field. In Microlino 2.0 project, it has a development key role: design E/E (electric/electronic) architecture, supply the vehicle ECU (Electronic Control Unit) which operates both as BCM (Body Control Module) and VCU (Vehicle Control Unit) and HMIs (Human Machine Interface) cluster like screen and touchpad. The aim of this work is to create the powertrain model in order to evaluate the State Of Charge (SOC) of the battery. Model implementation and computations have been made in MATLAB/Simulink framework. Two models are going to be analysed and studied: one for Mule Prototype and one for Prototype 4. The two models receive some inputs like accelerator and brake pedals positions, together with wheels speed and battery maximum discharge/charge current. The output is the computed value of the SOC. Between inputs and the output main powertrain components like Electric Motor, Inverter and Battery are modelled by using an energy point of view. Model validation is obtained using CAN data acquisition on track, made during some testing in prototyping phase. When the SOC, outputted by Simulink, corresponds with SOC caught on CAN the validation of the two model is confirmed
