Abstract: The aim of this paper is to present the implementation of regenerative brake system in electric vehicle operated on battery. Regenerative braking improves the efficiency of vehicle by recovering Kinetic Energy energy feedback to the energy storage system. The energy lost during deceleration period which is now recovered, stored in battery and super capacitor and then used in other applications. Regenerative brakes allow batteries to be operated for longer periods of time without the need of plugging charger. Thus the energy consumption reduces because of recovery and reutilization kinetic energy which leads to the increase in energy stored and improves efficiency with extending the driving range (Km/h). At the same time battery combine with the super capacitors will increasing the life expectancy and fuel economy of the battery and whatever energy stored in deceleration period is first feed to the motor in acceleration period. The system is used to MOSFET operated as buck-boost converter; this MOSFET is connected to super-capacitor. When the electric bike runs of high speed, the controller keeps the super-capacitor discharge. If the bike is not running the SC, remains charged as full voltage. The electrical braking system not only improves the comfort of riders but also increase safety of rider and electric vehicle as well. The proposed hardware model is implanted and simulated in MAT-lab Software.
