Model predictive control for the power-split between supercapacitor and battery for automotive applications

Research and development of energy storage systems are almost entirely dominated by the need for continuously increasing their performance, reducing weight, cost, and increasing efficiency. The combination of battery and supercapacitor within the hybrid energy storage system (HESS) involves the management of the power between the two devices. The objective of this study is to develop a novel model predictive controller for the HESS of a through-the- road-parallel hybrid electric vehicle, which aims to extend the battery life. Results in terms of battery life expectancy and HESS energy efficiency are presented and discussed.
