MATLAB/Simulink Modeling of Regenerative Recovery Circuit with Bidirectional DC-DC Converter for Scooter

Abstract

Scooter, which is in the class of light electric vehicles, is a very common transportation vehicle, especially in big cities. Brushless direct current motor (BLDCM) is preferred in scooters. These motors are a type of electric motor used in light electric vehicles (LEV) due to their features such as high efficiency, long operating life, high speed and silence operation. Although the BLDCMs used in the propulsion system of the scooter have high efficiency, they do not have a long range due to their limited battery capacity. The biggest problem with scooters is their short range. In order to solve this negativity, manufacturers are working on different solutions. In this study, MATLAB/Simulink modelling of bidirectional DC-DC converter regenerative recovery circuit for scooter was carried out. It is aimed to increase the range with regenerative recovery. The system in the proposed study is implemented for a 300W BLDCM with a rated voltage of 24V. The effect of bidirectional DC-DC converter regenerative recovery is proven by MATLAB/Simulink results.
