Use of Supercapacitor with Li-ion Battery as an Energy Storage System (ESS) for a two wheeler can be implemented in a variety of configurations with the aim to improve the cycle life of Li-ion batteries by decreasing the current transients they are subjected to, and to increase the peak power capability of the Power pack. MATLAB/SIMULINK tool is used as simulation software to model the Road Profile, Vehicle, Electric Powertrain and the Hybrid ESS (HESS). In this paper, the effect of different topologies of HESS and effect of degree of hybridization is analyzed w.r.t. current profile, voltage profile and State of Charge (SOC). Results show that use of HESS for Electric two wheeler in place of battery decreases the Peak/RMS Current experienced by the battery with corresponding improvement in battery life.

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.
