Abstract: A power supply device for a hybrid or electric motor vehicle, in particular a passenger vehicle or a motorcycle, includes a plurality of electrochemical storage cells and/or double-layer capacitors. The electrochemical storage cells and/or double-layer capacitors have a casing surface and, in an axial direction, a base surface and a cover surface which are connected by the casing surface, and each include electrodes. Adjacent to the casing surface of at least one of the storage cells and/or double-layer capacitors, a heat-conducting cooling apparatus is disposed which, although electrically insulated from the at least one storage cell and/or double-layer capacitor, is in thermal contact with a first circumferential section of the casing surface and dissipates the heat energy introduced by the casing surfaces of the at least one storage cell and/or the double-layer capacitor.

Abstract: For controlling the charge state of a battery in a hybrid vehicle having an internal-combustion engine and an electric machine, the battery is operated in a working state-of-charge range falling within a theoretically possible state-of-charge range. In a first sub-range, the battery is charged by the electric machine, the electric machine working as a generator and being engine driven. In a second sub-range, the battery is neither charged nor discharged, the electric machine working as a generator and being driven by the engine and, in the process, supplying only an on-board power supply system of the hybrid vehicle with current. In a third sub-range, the battery is discharged and, in the process, supplies the on-board power supply system with current, the electric machine running along passively. In a fourth sub-range, the battery is discharged and, in the process, supplies current to the electric machine operating as an electric motor.

Abstract: An emergency locking system and method is provided for power windows and/or power sun roofs in motor vehicles. It incorporates the feature that an obstruction safety interlock continues to be active even during the emergency locking mode in emergency situations and can only be disabled under specific conditions. In this way, injuries caused by a lack of information or improper operation can largely be excluded.
