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 |
20120274286 | METHOD AND DEVICE FOR IMPROVING THE PERFORMANCE OF ELECTRICALLY POWERED VEHICLES - A method for improving the performance of a traction battery during a driving start phase of an electric vehicle. A driving start point in time at which the driving start phase begins is provided. A temperature of the traction battery is detected. This temperature is compared with a minimum operating temperature, and the traction battery is heated if the comparison reveals that the temperature of the traction battery is below the minimum operating temperature. The heating takes place with a temperature increase which provides a temperature of the traction battery at the driving start point in time, which is no lower than the minimum operating temperature. | 11-01-2012 |
20140023923 | STRUCTURED ARRESTER FOR BATTERY CELLS - An arrester for a battery cell is described, the arrester essentially being formed from a conductive foil, wherein the conductive foil has structural components which enlarge the effective contact area between the foil and an active mass covering the foil when compared with the basic area of the foil. In addition, a method is described for producing a corresponding arrester and a battery cell having such an arrester. | 01-23-2014 |
