Experimental Verification of a Regenerative Braking System with an SOC Based Energy Management System for an E-Rickshaw Motor

India’s public road transportation system . These vehicles have grown in popularity as a convenient and
cost-effective means of transportation for fellow commuters. But e-rickshaws are not provided with regenerative braking system.To address this issue, this paper proposes a simple and cost-effective regenerative
braking system for e-rickshaw motors, which incorporates an energy management system based on state of charge of the battery. The proposed system is capable of functioning even when the battery is fully or close to being fully charged state.Additionally, it eliminates the need for any supplementary current or voltage sensors, which significantly reduces the complexity and cost of the circuit.To evaluate the system’s performance under various traction conditions, simulations and tests were conducted using the MATLAB/Simulink model. The results confirmed the high capabilities of the proposed system.The functionality and effectiveness of the proposed regenerative braking system were validated through laboratory experiments conducted under various conditions, including different speeds and levels of braking force, on a prototype equipped with an e-rickshaw motor.The results of the experiments demonstrated that the proposed regenerative braking system was successful in achieving its intended purpose, even with the fully charged battery, and without the need for any additional current sensors or voltage sensors thus making it a simple and cost-effective solution for e-rickshaws.
