The Regenerative Braking System in Electric Vehicle with Boost Converter is an energy-efficient system designed to recover and reuse the kinetic energy normally lost during braking. In this project, a DC motor coupled with a wheel arrangement acts as both the driving motor and generator. During the braking condition, the rotational energy of the wheel is converted into electrical energy through the 12V 100Watt DC motor operating in generator mode. The generated electrical energy is then processed using a boost converter to increase and stabilize the output voltage before storing it back into the 12V 9AH Li-ion battery. The system uses a PIC microcontroller for controlling and monitoring the complete operation. Voltage sensors are used to measure the battery voltage and generated voltage during regenerative action. A unidirectional current flow circuit is employed to ensure safe charging of the battery and to prevent reverse current flow. The LCD display unit continuously shows the voltages of battery and generated voltage. The proposed model improves overall energy efficiency of electric vehicles by reducing energy wastage during braking and extending battery backup time. The boost converter helps in maximizing the recovered energy even at low rotational speeds. This project demonstrates a simple, low-cost, and efficient regenerative braking mechanism suitable for electric bicycles, electric vehicles, and other renewable energy-based transportation systems.
