Simulation and Comparative Analysis of Energy Storage Systems for Light Electric Vehicle

Abstract

Now-a-days it can be seen that most of people are focusing on cycling for exercising and short distance traveling due to unhygienic lifestyles and increase in environmental pollution and its harmful effect on human. Looking at such circumstances this paper is focused on to generate electrical energy produced by the person via paddling and later consume the same energy for automatic running of the cycle. The demand for Electric Bikes is growing throughout the world due its characteristics of zero emission effects and longer life cycle. An electric bicycle uses electric motors for the purpose of moving which run on different types of Batteries. These batteries undergo many charging and recharging cycles in running conditions. By use of various non-conventional energy sources various batteries worked as energy storage units can be charged which will reduce the required amount of external energy for charging the batteries which will also reduce the use of fossil fuels and also will help to reduce the environmental pollution. The theme of paper is comprised in two sections, in first part a paddling mechanism is proposed which will do the energy conversion from mechanical to electrical and in later part the stored electrical energy is converted into mechanical energy to run cycle on charged batteries. A comparative analysis is also proposed for different batteries to find out efficient types in terms of economic aspects such as cost, thermal runaway, etc. in this work an electric generation mechanism by paddling the cycle is proposed for specified amount of time and based on that the generated electricity is calculated to be stored in battery for charging. Further the simulation results using MATLAB/Simulink has been analyzed for the proposed electric bicycle with different types of batteries, to study the various characteristics of the proposed set up with variation of battery parameters and distance covered by the cycle
