Based on a Brushless DC (BLDC) motor, this research provides a novel regenerative braking approach. The recommended approach for braking involves using a variable Stator voltage from a multi-cell battery system DC-DC buck converter. To evaluate the performance of the proposed braking system, a simulation was used. According to simulation results, the proposed regenerative braking technique is practical and efficient. Additionally, this research introduces the most fundamental technology for regenerative braking using a BLDC motor to improve the mileage of lightweight electric vehicles (EVs).
