Control of hybrid energy storage system for an electric vehicle

This paper presents the control of a hybrid energy storage system performance for electric vehicle application. The hybrid energy storage system helps to enhance the life of battery by reducing the peak power demand using an auxiliary energy storage system (AES) based on super capacitor and a bidirectional buck-boost converter. Further, the performance of an electric vehicle in various environments like acceleration, regenerative braking and normal speed of operation are simulated using the Saber RD software. The LabVIEW interfaced with Arduino controller is used to analyze the prototype hybrid energy storage system. The simulation results showed that the proposed hybrid energy storage system helps to decrease the peak power demand up to 54% from the battery system. The experimental results are presented, validating the simulation results.
