    Abstract: A machining system for electromachining a workpiece that in one embodiment includes a machine tool, a cutting tool for performing the eletromachining, and a tool holding apparatus for conductively holding the cutting tool and coupled to the machine tool. The tool holding apparatus includes a holding element for holding the cutting tool and at least one solution releasing element. The solution releasing element is used to receive machining solution and release the machining solution onto a predetermined area of the cutting tool through at least one group of channels. Each group of channels includes at least two channels configured to respectively release the machining solution onto at least two adjacent sections in the predetermined area of the cutting tool.

    Abstract: An electric drive system includes an energy storage system (ESS), a power conversion system, and an alternating current (AC) traction system. The ESS provides or receives electric power. The ESS includes a first energy storage unit and a second energy storage unit. The power conversion system is electrically coupled to the ESS for converting an input power to an output power. The AC traction system is electrically coupled to the power conversion system for converting the output power of the power conversion system to mechanical torques. The AC traction system includes a first AC drive device and a second AC drive device. An energy management system (EMS) is in electrical communication with the ESS, the AC traction system, and the power conversion system for providing control signals.
