Abstract :Electric motors are more efficient than internal combustion engines. This puts forward electric vehicles more popular than fossil fuel vehicles. However, electric vehicles have limited range because of insufficient batteries. For this reason, studies focus on increasing the range of electric vehicles. Regenerative braking is a solution that helps this problem. It utilizes kinetic energy of rotating wheels during braking and converts kinetic energy into the electric energy via induced voltage on the motor phases. In this study, a new regenerative braking modeling and application was performed under different speeds for a hub type brushless direct current machine (BLDC) used on electric bicycle. The modeling results were compared with the application results and they verified each other. The analyses have showed that gain and efficiency which attain from the regenerative braking increased at higher speeds of hub type BLDC. Ultimately, the energy recovery of 6.37% was saved by means of the regenerative braking of the hub type BLDC used on electric bicycle at 320 RPM.
