Control for a Supercapacitor Hybrid Energy Storage System Used in Electric Vehicles
This paper proposes the control strategy of a fully active hybrid energy storage system, which uses two bi-directional DC/DC converters to decouple supercapacitors and the battery pack from the DC bus. A Lyapunov-function-based controller regulates DC bus voltage, and a sliding mode controller, controlling the battery and supercapacitor currents, is designed. Their performance is validated by simulation and experimental data.
