Active Hybrid Energy Storage System for Electric Two Wheeler 2020-28-0516

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.
