Abstract: A method including a) running through at least two cycles of a cycling process for measuring parameters within the cycles in the temporally first phase, b) manipulating measurement data formed by the parameters measured over the cycles in a second phase in such a way that at least one part of the measurement data from at least one part of the cycles is changed within the cycles with respect to parameters at least partially correlating with an upper voltage limit and a lower voltage limit, c) forming a generated measurement data set for the part of the cycles in such a way that modified at least partially correlating parameters of the manipulated part of the measurement data and the unmanipulated part of the measurement data from the part of the cycles are merged, d) generating signals representing the values of the generated measurement data, e) determining the aging.

Abstract: A method, a system and a computer program product for changing an electrical state of charge of an electrical energy storage: a) stipulating at least one target value for a target state of charge of the electrical storage device, b) determining at least one actual value of an actual state of charge of the electrical storage device, c) extrapolating the actual value of the actual state of charge of the energy storage device to an extrapolation value of an extrapolation state of charge of the energy storage device, taking into account at least one charging parameter of the charging process, and d) comparing the target value of the target state of charge with the extrapolation value of the extrapolation state of charge and starting or interrupting the charging process if the extrapolation value deviates from the target value by more than 2%.
