Electric and Hybrid Electric Vehicles

Sizing and analysis of the powertrain and battery of a heavy electric vehicle

The main focus of this project is to size the powertrain of a heavy electric vehicle. A methodology was developed to theoretically calculate motor and battery ratings that satisfy standard performance requirements. These were used for detailed evaluation of vehicle performance in AVL CRUISE using standard test procedures. Various motor drive configurations were considered for this work. Additionally, a study was conducted on the impact of the variation in test conditions allowed by various standards on motor ratings.

Current work includes optimization of dual motor all-wheel drive and dual motor torque and speed coupled configurations while considering the effects of regenerative braking, and the impact of hub motor configuration and battery placement on energy consumption, ride comfort, traction stability and rollover.

Design and Analysis of Hybrid Electric Powertrain for Military Tracked Vehicles

The objective of this research work is to design and analyze the hybrid electric powertrain with hybrid energy storage and multi-speed transmission for military tracked vehicle to satisfy the performance requirements on different types of terrains.

The scope of the research work includes

1. Design of suitable hybrid electric vehicle configuration and component sizing of the hybrid electric powertrain to meet these performance requirements.

2. Simulation and evaluation of the designed configuration and control strategy in AVL CRUISE, a commercial simulation tool for vehicle powertrain analysis.

3. Parametric analysis of control strategy to achieve better fuel economy and reduced weight with the same performance constraints and performance analysis of designed hybrid electric powertrain.
