LLife Cycle Assessment of Greenhouse Gas Emissions of Electric and Combustion Vehicles

Over the last decades, electric vehicles (EVs) have emerged as an alternative to combustion engine vehicles. EVs have different propulsion and fuel intake system when compared to combustion engine vehicles. Therefore, cradle-to-gate (CTG) and well-to-wheel (WTW) greenhouse gas emissions (GHGs) would be different. In this study, life cycle GHG emissions of vehicle cycle and fuel cycle are compared between EV and internal combustion engine (ICEV) powered by petrol and diesel as fuel. This study used the average curb weight of all three types of vehicles based on the availability and popularity in the Indian market (as a case study) for life cycle assessment. The Greenhouse Gases, Regulated Emissions, and Energy use in Transport (GREET) model developed by Argonne National Laboratory was adopted to conduct the life cycle assessment.  (M.Tech thesis 2021)

Emulating Real-World EV Charging Profiles with a Real-Time Simulation Environment

Electric vehicle (EV) charging is critical for grid integration and intelligent charging strategy development, but the variability of charging behavior and limited high-resolution data pose major challenges. This study presents a real-time simulation framework to emulate real-world EV charging using a physics-based charger model on the Typhoon HIL platform. The model captures detailed electrical dynamics and control logic, with outputs—active power and SOC evolution—validated against PMU field data. Results show strong alignment across charging phases, including SOC-dependent transitions, with an MAE of 0.14 and RMSE of 0.36. Practical BMS behavior, such as charging termination near 97% SOC, is also reflected. The framework offers a high-fidelity tool for grid impact analysis, smart charging control, and digital twin development for future EV systems.
