摘要： In a method for producing a product in a technical plant, after receipt of an order for producing the product, components necessary for producing the product are identified, and work steps necessary for producing the product are identified. Identified components and work steps are entered in a product file stored on a transport system. The components entered in the product file are acquired by the transport system, which is documented in the product file, and the work steps entered in the product file are executed, which is documented in the product file. The product file remains on the transport system until the acquisition of each component and the execution of each work step are documented in the product file. A technical plant for producing a product, is adapted to execute the method and includes a transport system having a digital data memory for storing the product file.

摘要： In a transport system and method for operating a transport system the transport system includes a first mobile component and a second mobile component as well as a transport rack. Bearing rollers for moving the transport rack on a driving surface are disposed on the transport rack, in particular, the mobile component is drivable on the driving surface. Each mobile component has a linear axle and a control as well as wheels driven by an electric motor. The first mobile component is able to drive underneath the transport rack in a first region of the transport rack, and the second mobile component is able to drive underneath the transport rack in another, i.e. second, region of the transport rack. The transport rack is able to be raised by extending the linear axles of the mobile components, in particular is able to be raised in such a way that the bearing rollers of the transport rack lose physical contact with the driving surface. A communications channel is provided between the first and the second mobile components, the communications channel serving as a transmission channel for data of at least one master-slave control, the first mobile component acting as a master and the second mobile component acting as a slave.

摘要： In a method for operating an electric vehicle, including a first energy storage device (e.g., a rechargeable battery storage device), a second energy storage device (e.g., a double-layer capacitor device), an energy supply unit which provides energy, for charging the first and/or second energy storage device, and a first electrical consumer connected to the second energy storage device via an intermediate circuit, the first energy storage device is connected to the energy supply unit via a bidirectional converter unit, the second energy storage device is connected to the energy supply unit, a first power flows from the first energy storage device to the second energy storage device if an intermediate circuit voltage falls below a definable voltage, and a second power flow from the second to the first energy storage device is prevented.
