A Study on the Regenerative Braking of Electric Scooter Using BLDCM

Recently, interest and demand for electric scooters, which are personal mobility, are increasing. As an electric scooter has limited travel distance and time due to its limited battery capacity, it requires regenerative braking that regenerates kinetic energy during braking operation. However, unlike electric vehicles, the electric scooter has its own operating conditions according its environment of use, so the regenerative braking method suitable for the electric scooter should be applied. In this paper, three braking methods used in electric scooters are selected, the characteristics of each method are compared and analyzed, and a braking method suitable for electric scooters is derived. Each braking method is confirmed through PSIM simulation using a BLDC motor, which is commonly used in an electric scooter.
