20100200190 | METHOD FOR COOLING AN ENERGY ACCUMULATOR - A method is disclosed for cooling an energy accumulator in a rail vehicle, using air. According to at least one embodiment of the invention, the air is fed to the energy accumulator directly from an already cooled or air-conditioned area of the rail vehicle. This occurs in particular when the temperature of the area is lower than the external temperature. | 08-12-2010 |
20100253146 | ELECTRIC DRIVE SYSTEM - An electric drive system, in particular for a rail vehicle, includes an electric energy accumulator and an electrochemical energy accumulator, connected in parallel. According to at least one embodiment of the invention, a component, e.g., a diode with a transmission direction facing away from the electrochemical energy accumulator, is situated in a connecting line between the electric energy accumulator and the electrochemical energy accumulator. | 10-07-2010 |
20100320835 | DEVICE FOR OPERATING A VEHICLE - A device for operating a vehicle, in particular a rail vehicle, is disclosed. In at least one embodiment, an energy feed device is connected to a drive device via a drive rectifier, and to an energy store via an energy storage rectifier. In at least one embodiment, there is provision that the energy storage rectifier can be reconfigured. Its output is connected to the energy store and to the drive device via switches, with the result that the energy storage rectifier can be connected to the drive device instead of to the energy store. | 12-23-2010 |
20110018492 | POWER STORAGE SYSTEM FOR A RAIL-GUIDED VEHICLE - An energy storage system for a track-guided vehicle includes at least one electrical energy storage device and at least one electrochemical energy storage device connected through at least one converter to a supply line and to a drive unit for the vehicle. Individual phases of said at least one converter can be operated as independent direct-current controllers for independent charging and discharging of different energy storage devices. | 01-27-2011 |
20120055659 | DEVICE FOR EXCHANGING HEAT COMPRISING A PLATE STACK AND METHOD FOR PRODUCING SAID DEVICE - 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. | 03-08-2012 |
20120219837 | APPARATUS FOR ELECTRICAL ENERGY STORAGE - 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. | 08-30-2012 |
