Study for developing the energy recovering circuit for modern e-bike controller

The aim of this paper is to present the implementation of an energy recovery system based on BLDC motor deceleration, in order to be used in e-bike´s propulsion systems. The energy which should be lost during deceleration is now recovered, stored and then used in other applications. The energy recovery and reutilization leads to a considerable decrease in total energy consumption necessary for traction mode. At the same time combining with the super capacitors usage is protecting the life expectancy of the battery, which normally supplies the propulsion system of an electric motor.
