In this paper, power management technology in wireless Power transmission system is researched. According to characteristics of quick charging, higher capacity and stable voltage,we adopt a hybrid energy storage system of ultra capacitor and battery. First the diagram of system is presented. Then power management technology of the energy storage system is studied. A S3R shunt regulating method for PCU and wide range dual switch forward DC/DC converter for ultra capacitor method is researched. With our studies, problems are solved of quick discharging, voltage bus power balancing and multiple power supplies managing,which can promote WPT technology development efficiently.
