Abstract:

Lithium-ion battery/supercapacitor hybrid energy storage system has become the most widely used hybrid energy storage system because of its good performance, low cost and strong versatility. Energy management method is one of the core technologies of hybrid energy storage systems, and it is also the main research focus at present. In order to systematically review the energy management methods of hybrid energy storage systems, this paper first introduces the topology structure, energy management architecture and power distribution control of lithium-ion battery/supercapacitor hybrid energy storage systems. Then, this paper divides the existing energy management methods of hybrid energy storage system into four categories: experience based, optimization based, working condition pattern recognition based and machine learning based, and the efficiency of each type of energy management methods is discussed respectively for regular and random conditions; the robustness and computational complexity of each method are also analyzed. Finally, the current energy management methods are summarized and the future research directions and development trends in this field are prospected. Comprehensive analysis shows that improving the prediction accuracy of stochastic load in the future, establishing a more accurate hybrid energy storage system model, and further improving the real-time performance of energy management methods through cloud collaboration will be the focus of future energy management research of hybrid energy storage systems.
