ENERGY ENHANCEMENT OF ELECTRIC VEHICLES THROUGH REGENERATIVE BRAKING SYSTEM

Abstract

Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) have been attracting a lot of attention for environmental issues and energy crisis. One of advantage of using foregoing vehicles is charging energy by regenerative brake. Regenerative braking systems (RBS) are a useful way to capture the energy lost while braking and at the same time lowering exhaust and brake emissions. The idea behind this process is to transform mechanical energy from a motor's kinetic energy into electrical energy. This paper, gives comprehensive information about regenerative energy system. Later, a case study of an electric vehicle conversion's electrical energy use in a real-world setting has been looked at. Such tests assess the energy usage of a vehicle's overall system whether it has regenerative braking or not. The absorbed capacity of regenerative energy is limited because of motor capacity and current limit of battery. This becomes serious issues the heavy weight vehicle such as bus and truck. To increase regenerative energy, large motor and battery are requested, which is difficult because of cost and limit of inverter capacity. With the advancement of energy regeneration technologies, the driving range of electric vehicles can be enhanced. Two boost approach, a unique energy regeneration strategy, is suggested in this paper for electric vehicles powered by brushless DC motors. Additionally, since this approach regenerates more energy than the single boost method, this method's energy regeneration efficiency has been greatly improved.
