Abstract: The present disclosure provides a switched reconfigurable multi-converter multi-source energy storage system configuration for electrified vehicles comprising of multiple dc/dc power converters, multiple energy sources, a mode selector switching module further comprising a plurality of controllable switches and a controller. A method of switching to reconfigure the multi-converter multi-source energy storage system during the dynamic events of variable power demand or regeneration in an electrified vehicle is disclosed. Furthermore, a power flow control scheme for executing the dynamic switching methods of reconfiguration to maneuver the flow of power within the system during different scenarios of forward power delivery or reverse power accumulation is disclosed. The controllable switches are methodically activated or deactivated to couple or decouple the energy sources to or from the input side of the dc/dc power converters by means of necessary activation or deactivation signals from the controller.

Abstract: The technology described herein discloses a non-isolated multiport dc-dc converter with three input dc ports to integrate three different energy sources namely fuel cell, battery and ultracapacitor, and two dedicated output ports for traction load and auxiliary loads, respectively. The invented system is capable of providing high flexibility in power flow management among the three energy sources, corresponding to diverse dynamic load power events encountered in an EV. Besides, the system exhibits prominent features like simultaneous and bidirectional power transferring capability between the multiple dc ports and single stage power processing in every possible power flow scenarios. Furthermore, the technology embodies distinct operating modes depending upon the dynamic load power variations and state of voltage levels of the energy sources.
