Patent number: 10343534Abstract: An arrangement for inductively transmitting energy for charging an energy storage device of a rail vehicle. A first induction element transfers energy to a second induction element. An inverter with an adjustable AC voltage frequency provides an AC voltage to the first induction element. A controller controls the AC voltage frequency of the inverter. A measuring device ascertains a power output value during the wireless energy transmission and transmits the value to the controller and the controller adjusts AC voltage frequency of the inverter downward from an upper threshold until a pre-specified power output value is set while energy is being transmitted. The first induction element is paired with a track for rail traffic. The system and a method are also described for inductively transmitting energy for charging an energy storage device of a rail vehicle.Type: GrantFiled: May 8, 2015Date of Patent: July 9, 2019Assignee: Siemens Mobility GmbHInventors: Rolf Fischperer, Jens Helfrich, Jochen Mast, Michael Meinert, Jean Schutz

Patent number: 8940426Abstract: A device stores electric energy, in particular for the traction supply of a rail vehicle. The device has a plurality of chargeable storage cells with cell poles, a cooling body that is in thermal contact with the storage cells, and a plurality of bridge members, by way of which two of the plurality of storage cells are in electric contact. Accordingly, at least some of the bridge members contact the storage cells on the sides thereof facing the cooling body. A bridge member contains a connecting web having two recesses and two connecting parts, each being introduced into one of the recesses. Each connecting part is connected to a cell pole of a storage cell to be contacted. The connecting parts are fixed non-rotatably and non-displaceably in a connecting web by a releasable tensioning device. Thus the efficiency and service life of the energy storage device can be increased by reducing the thermal resistance between the storage cells and the cooling body.Type: GrantFiled: June 22, 2010Date of Patent: January 27, 2015Assignee: Siemens AktiengesellschaftInventors: Bruno Gebhard, Alexander Hahn, Norbert Huber, Michael Meinert, Karsten Rechenberg

Publication number: 20120087092Abstract: A uniform temperature of the machines to be cooled is obtained by way of a device for cooling at least one power component. The device has a cooling medium line, a cooling medium pump and a heat exchanger. Furthermore, streams of cooling media are to be kept low. A return runs back in the direction of an inlet along a flow up to an outlet. In this way, a counter stream interconnection for averaging a flow and a return temperature of a cooling medium is achieved.Type: ApplicationFiled: April 27, 2010Publication date: April 12, 2012Applicant: SIEMENS AKTIENGESELLSAFTInventors: Norbert Huber, Michael Meinert, Armin Rastogi, Karsten Rechenberg

Publication number: 20120055659Abstract: A device for exchanging heat has a plate stack of at least a first, a second, and a third plate. The three or more plates are stacked one on top of the other and have recesses which are arranged in a regular pattern on a plane of the respective plates. The first and the second plates as well as the second and the third plates are stacked in such a manner that each adjacent plate forms at least one common cooling channel, which is accessible to a fluid, running in a direction on the plane of plates. The two or more cooling channels are formed by way of recesses, which partially but not entirely overlap, in the adjacent plates. The one or more cooling channels of the first and second plates are entirely spatially separated from at least one cooling channel of the second and third plates.Type: ApplicationFiled: April 15, 2010Publication date: March 8, 2012Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Norbert Hubert, Michael Meinert, Armin Rastogi, Karsten Rechenberg
