The hybrid energy storage system composed of lithium battery and super-capacitor exerts the maximized complementary characteristics of energy density and power density from each part separately, therefore attracts great attention in the field of rail transit vehicle on-board energy storage, whereas the efficiency optimization requires immediate amelioration. From the perspectives of energy storage subsystem and hybrid energy storage system, the research progress on power efficiency optimization in hybrid energy storage system is elaborated, the factors affecting the subsystems, the efficiency of systems, and the optimization methods based on these factors are summarized. The influence level of these factors, the merits and demerits of the optimization methods are comparatively analyzed, key problems on energy efficiency improvement in hybrid energy storage system are put forward. Finally, the prospect of efficiency optimization of on-board hybrid energy storage system is presented, providing reference for the design and control of on-board power system in rail transit.
