SEE SAW BASED REGENERATIVE POWER SYSTEM

Research related to electrical vehicles is gaining importance due to the energy crisis. Using regenerative braking when braking, improves the efficiency of an electric vehicle as it recovers energy that could go to waste if mechanical brakes were used. A novel regenerative br aking system for neighborhood electric vehicles was designed, prototyped and tested. The proposed system utilizes a seesaw system to capture energy whereas the conventional systems regenerate to the batteries. The user has direct control over the amount of current regenerated and hence the amount of negative torque applied for braking. The research has shown that the proposed regenerative braking system is significantly better in recovering energy and slowing the vehicle compared to a commercially available regenerative braking system. Regenerative Braking System (RBS) is an efficient system to reduce vehicle emission and fuel consumption. RBS is a system which converts mechanical energy to electrical energy during braking action. It will become an important system for future vehicle such as hybrid and electric car. The important components used in RBS will be determined such as electric motor, motor controller and battery. To produce a RBS model, a seesaw conversion system has been made in college and a dyna mo was selected to be installed in the model. The results and calculations show that device can function properly, that means device can form recovery energy to charge battery during braking. During the recovery energy working, brake effects are formed to decelerate the bike. In addition this RBS model can be used for future study.
