Regenerative braking control model and simulation for an electric scooter

Advances in technology have brought about the creation of an electric scooter as a means of transportation and recreation. Also, new advances suggest improvements in the existing electric scooter to make it more efficient by extending the battery life. The battery life of the electric scooter can be extended through regenerative braking. Existing methodologies are examined, and a new scooter design is constructed in Solidworks with the inclusion of a hub motor to be used in driving the scooter and also in the application of regenerative braking. Using the Simulink and Matlab software, a motor control model is created and included in the development of the scooter simulation. The scooter simulation is used to analyze the benefits of the regenerative braking process. An average run was simulated to calculate battery charge flow by assuming average regenerative brake usage of 20% and average throttle (75%) applied for 80% of a full battery cycle. The average run regenerative braking usage indicated an increase in battery charge and battery life by 30%
