Modeling, simulation and experimental verification of an electric bicycle with regenerative braking

Electric bicycles are widely available in user markets. However their use as a dailycommuting vehicle is limited due to the need for frequent recharging. This thesis focuseson the mathematical modeling of electrical bicycle with regenerative breaking. Basic bondgraphs methods are discussed here to develop state space models for mechatronic systems. Abond graph based mathematical model of an electric bicycle with regeneration is developed inthis thesis. Mathematical models are tested in simulation, generating different road scenarios.Parameters required for the simulation are calculated using an experimental setup. Thethesis shows the capability of bond graphs to assist in calculations for regenerative charging.The main focus of this thesis is to evaluate simulation models against a prototype. Simulationresults and road testing of the prototype indicate the regenerative braking is not only feasible,but an advantage to implement in an electric bicycle. It is shown that the distance betweenbattery recharge is improved by as much as 10% depending on riding conditions.
