An exemplary electric drive system includes an energy storage system (ESS) 11, a power conversion system 13, and an alternating current (AC) traction system 15. The ESS 11 provides or receives electric power. The ESS includes a first energy storage unit and a second energy storage unit 14. The power conversion system 13 is electrically coupled to the ESS 11 for converting an input power to an output power. The AC traction system 15 is electrically coupled to the power conversion system 13 for converting the output power of the power conversion system to mechanical torques. The AC traction system 15 includes a first AC drive device 20 and a second AC drive device 22. An energy management system (EMS) 17 is in electrical communication with the ESS 11, the AC traction system 15, and the power conversion system 13 for providing control signals. An energy management method is also described.
