Cell Assembly having a Plurality of Electrochemical Cells and Method for Operating said Cell Assembly

摘要

A method includes activating electrochemical cells of a cell assembly to output electrical energy in accordance with a superordinate clock signal in order to have an activation and/or switch-off time points of the respective cells on the basis of the superordinate clock signal not all occur at the same time. To reduce the complexity of smoothing the total battery voltage, the switching time points according to the disclosure are shifted on the basis of the superordinate clock signal for the first cell in accordance with a first switching specification by a cell-specific first clock shift signal.

1. A method for operating a plurality of electrochemical cells of a cell assembly, said method comprising:
defining a first switching command for a first electrochemical cell of the cell assembly; generating a master clock signal so as to connect the first electrochemical cell and an electrochemical second cell to the cell assembly and/or so as to disconnect the first electrochemical cell and the second electrochemical cell from the cell assembly; and postponing a point in time at which the first electrochemical cell is connected and/or disconnected in accordance with the first switching command with a cell-specific first clock shift signal.
