Hybridization is important to obtain the advantages of both the engine and motor as the sources of propulsion. This paper discusses the effect of hybridization of powertrain on vehicle performance. The Hybrid architectures are differentiated on the basis percentage of power dependency on the engine and motor. Passenger car with hybridization ratios of 20%, 40%, 60%, 80% and 100% are modelled on MATLAB/Simulink using the backward facing approach with the engine and motor specifications remaining constant. The hybridizations ratios and the energy consumption in terms of fuel and battery energy are obtained from the model and compared. Neural network is implemented to determine the fuel consumption. The outputs can be used by a system designer to determine a desirable hybridization factor based on the requirements dictated by the specific application.

This paper deals with the concept design of a mini tractor which is suitable for mild ploughing operations with 5 kW electric motor. The low cost battery driven mini tractor operates on a lead acid batteries. The design principles and calculations of electric tractor powertrain are studied and delineated in details. By using these calculations, parameters of the major powertrain components like drive motor, battery and transmission are obtained. The powertrain model of an electric tractor is modelled with MATLAB/Simulink to estimate the traction and battery performance. The CAD model of tractor is prepared in Solidworks and CAE analysis of chassis is performed using ANSYS Workbench to ensure safety and reliability. Calculations are performed for tractor subsystems such as steering system and braking system. The analysis results confer the design as safe and satisfactory in terms of performance.

Driving cycle predicts the range of an electrical vehicle under controlled conditions and certain driving cycles can significantly affect vehicle performance. during this paper, driving cycle effects on performance parameters and range are studied by considering a proposed small electric vehicle. Simulations are administered in Matlab/Simulink. Vehicle parameters like top speed, acceleration, final drive reduction ratio and battery current are compared with energy economy of small electric vehicle. supported simulation results the driving cycles fitted to urban mobility are ECE R 15 and JP – 10 mode. The proposed small electric vehicle designed considerately to satisfy the need for urban mobility and meet the range of atleast 200 km

With the fossil fuels being depleted very fast, the current energy scenario is very difficult and damaging for current and following generations. To boost some effective contribution towards the awareness in alternate fuels & energy, in this project, an electric All-terrain vehicle (ATV) roll cage is developed with utility factor, analyzed and validated physically with all-round performance of the vehicle. The objective of this project is development of electric All-Terrain Vehicle roll cage according to SAEINDIA rules, finite element analysis (FEA) for design validation, feasibility, safety and physical testing at event site. The roll cage is modified from one seater vehicle to three seater vehicle with luggage allowance, which is a good utility addition for an all-terrain vehicle. Transformation from gasoline vehicle to electric vehicle is also considered while development & analysis. The developed roll cage is tested under static & dynamic loading conditions. From the Finite Element Analysis and testing, the factor of safety obtained is above 2 for all cases and thus it can be inferred that the vehicle roll cage is safe, feasible and can sustain the loading environment for various cases it has been designed for and also it passes AIS Standards. This electric all­terrain vehicle development will have actual utility after the event unlike regular all-terrain vehicles, as well as it will impart awareness about electric vehicles.
