| 20080233471 | Battery State Detection - A battery state detection arrangement is provided for use in conjunction with a series connection of multiple battery cells, e.g., a series connection of at least two lead batteries in a vehicle electric system having a voltage which is higher than conventional system voltages. The battery state detection arrangement detects both a defect in a battery and a defect in the overall system and transmits signals to a higher-level energy management system as well as, if necessary, a display. Additional components provide a charge equalization in the batteries by selectively recharging or selectively discharging unevenly charged batteries. | 09-25-2008 |
| 20090326748 | Method for Controlling a Hybrid Vehicle and Hybrid Vehicle - A method for controlling a hybrid vehicle having at least two propulsion engines. According to the specification of an operating controller, propulsion is provided via the first propulsion engine, in particular an internal combustion engine, and/or the second propulsion engine, in particular an electric motor. The percentage contribution of the propulsion of the second propulsion engine is controlled as a function of the data pertaining to the travel route communicated to the operating controller, taking into account a charge state of an energy accumulator. An optimized operating strategy is determined by specifying a geographic destination and/or a destination parameter of the operating strategy, the travel route being selected by taking into account the optimized operating strategy when alternate travel routes are available. | 12-31-2009 |
| 20110151335 | Lithium-sulfur cell and method for manufacturing - A lithium-sulfur cell comprising an anode structure, a cathode structure and an electrolyte section abutting to the cathode structure. The cathode structure comprises a continuous layer of nanotubes or nanowires and sulfur particles. The sulfur particles are attached to the nanotubes or nanowires. The continuous layer of nanotubes or nanowires abuts to at least a part of the electrolyte section. The invention further relates to a corresponding method for manufacturing the inventive cell. | 06-23-2011 |
