A method for determining an overall loss of capacitance of a secondary cell, for example of an accumulator, which is brought about by ageing processes is provided. The overall loss of capacitance is determined additively from partial losses of capacitance which are determined by means of various parameters from various functions. A partial loss of capacitance is determined under constant peripheral conditions. If the peripheral conditions change, the partial losses of capacitance follow one another directly, i.e. with respect to the same loss of capacitance. The interval of the respective charge throughput rate is shifted here. The overall loss of capacitance of a secondary cell can be extended to the overall loss of capacitance of a package composed of a plurality of secondary cells.

Electric fields control an electric combustion. Plasmas are created by a dielectrically impeded discharge. At least one part of the fuel is mixed with water vapor in the supply line and is subjected to a plasma discharge in a compact reactor that is in close contact with the burner in terms of reaction kinetics. In the associated device, a plasma reactor for creating a reactive plasma gas with at least one supply line for the fuel gas-water vapor mixture and an electric energy supply is integrated into the burner. The device provides suitable flow guidance of the fuel gas-air mixture, of the fuel gas-water vapor mixture, and of the reactive plasma gas.
