In the internship, Interns delve into various topics, including understanding the EV powertrain system and its dynamic behavior, exploring parameters that influence performance, studying driving cycles and their significance (such as NEDC, Artemis Rural/Urban/Highway, FTP-75, WLTP, RDC, acceleration and gradient test cases), comparing drive cycles, generating real-time drive cycles with test vehicles, modelling resistive forces that affect vehicle performance (rolling resistance, grade resistance, aerodynamic resistance, acceleration, and inertial forces), and analyzing the impact of each force on performance. This module also includes tasks like creating traction battery models, performing hand calculations for pack parameter estimations, understanding cell datasheets, and modelling packs to evaluate battery power, current, operational C-rates, energy consumption per kilometer, total energy consumption for drive cycles or required range, and configuring cell connections in series and parallel. Additionally, interns undertake vehicle projects involving the Ather 450X, Nissan Leaf, and Student Formula vehicles. By the end of week 4, interns will gain the ability to analyze the effects of each parameter, make analytical decisions based on simulation results, and select components such as transmission gear ratios, electric motors (torque, RPM, power), battery packs (capacity, current, C-rate, energy per kilometer), conductors (wires, busbars), and contractors/fuses (maximum current).
