Optimización de la autonomía de un scooter eléctrico mediante la integración de un sistema de freno regenerativo

Abstract

The objective of this degree project is to implement a regenerative braking system in a scooter to take advantage of the braking cycles to recover battery energy and optimize the vehicle's autonomy. This topic is of great relevance since it adds to the proposals to promote electric mobility using the kinetic energy of the vehicle that is normally wasted during deceleration. The methodology used in the study was quantitative and experimental. Information was collected through a survey among several users to better understand the needs and expectations regarding the regenerative braking system. Subsequently, the technical characteristics of the original scooter engine were analyzed to determine the best option in terms of replacement components to implement a regenerative engine without having to modify the structure or alter other components of the vehicle. The tests carried out focused on routes with short, medium and long routes in which the battery wear was measured when using the scooter with the original motor and with the regenerating motor. Subsequently, a comparative analysis was carried out, in which key parameters were considered such as: distance traveled, duration time, combined load (weight of scooter and driver), battery wear, average speed and speed. maximum. The results obtained allowed us to evaluate the performance of the implemented regenerative braking system, confirming its feasibility as it allowed us to improve the energy efficiency and autonomy of the electric scooter.
