Abstract:

The use of light electric bikes is becoming more and more common as people become more concerned about pollution, traffic, and energy use. E-bikes have distinguished themselves among these vehicles as a practical, user-friendly solution with a compact design. These vehicles include electric motors and batteries for propulsion and come in a variety of shapes, from large models that resemble gasoline scooters to smaller ones with bicycle-like designs. With top speeds averaging about 30 km/h and weights ranging from 30 to 80 kg, they all share comparable technology despite their variances in appearance. In order to examine numerous electrical characteristics in the output as graphs, the lightweight and effective drivetrain of e-bikes has been studied using MATLAB Simulink. Electric vehicles (EVs), which are already widely used, are the most significant invention of this decade. The amount of energy in the EB's internal battery determines how far it can travel. The capacity of EBs to recover energy while braking is a crucial characteristic. Braking force is generated by the brushless DC motor under control, and this braking energy is captured and stored in an ultra-capacitor. Reusing this stored energy will boost the system's effectiveness and driving power and range. The development of new, energy-efficient batteries, such Li-ion, is the subject of continuous research in the field of batteries.
