摘要： An energy storage device for storing energy for a stationary AC voltage grid includes a control device; and at least two switching units. Each switching unit includes multiple storage elements for storing a part of the energy, a converter having an AC voltage connection for connection to the AC voltage grid and a DC voltage connection, and a multiplexer switching device electrically connected with the DC voltage connection of the converter and with one of the storage elements via a respective storage connection. The multiplexer switching device is configured to select one of the storage connections in dependence on a selection signal generated by the control device and to electrically connect only the one storage connection selected by multiplexer switching device with the DC voltage connection of the converter. The control device is configured to control the converter of each of the at least two switching units so as to gradually reduce an energy flow between the AC voltage grid and a first one of the switching units and to correspondingly increase an energy flow between the DC voltage grid and at least one second one of the switching units until the energy flow between the AC voltage grid and the first switching unit is reduced to zero.

摘要： A protective device for shutting down at least one battery cell in a battery system of a motor vehicle in case of an electrical short circuit. The protective device is configured to conduct an electric current, which flows through the at least one battery cell, through a measurement element, in which the current generates an electrical measurement voltage in dependence on its amperage and/or its amperage gradient. The measurement element is coupled to an analog monitoring circuit, in which a comparison unit is configured to trigger a triggering signal for the case that the amperage rises at least by a predetermined delta value within a predetermined duration, and a switching unit is configured to receive the triggering signal and to interrupt the current upon receiving the triggering signal by switching at least one switching element.

摘要： A method for operating a battery of an at least partially electrically operated/driven functional device, a corresponding battery, and a corresponding functional device. A control unit of the battery receives measurement signals relating to a respective parameter of the battery cells from a plurality of switchable battery cells of the battery. The control unit prepares a location-resolved distribution function of the respective cell parameter within the battery on the basis of the measurement signals. By activating the switching elements of the switchable battery cells according to a predetermined switching rule, the control unit produces a pattern of battery cells switched to active and passive. A predetermined location-resolved distribution function of the respective cell parameter is fulfilled and at least one predetermined secondary condition relating to an operation of the functional device and/or the battery is maintained.

摘要： A method for monitoring a state variable of at least one battery cell of a battery. The battery has at least two battery cells that are arranged adjacent to one another. A first electrically conductive surface is provided at a boundary surface of a first battery cell and a second electrically conductive surface is provided at a boundary surface of a second battery cell. The electrically conductive surfaces are arranged electrically insulated from each other. An electrical voltage is applied between the two electrically conductive surfaces. An electrical variable produced due to an effect of the electrical voltage is analyzed. The state variable on the basis of the analysis is determined.
