Abstract: Described and shown is a process for preparing an emergency energy storage device, with at least one energy storage element for operation, whereby the emergency energy store is designed to provide emergency electrical energy for at least one energy consumer, whereby the energy (EL) which can be drawn from the emergency energy storage and/or the peak output (Pmax) which can be drawn from the emergency energy storage is determined and the operational readiness is established as soon as the energy (EL) which can be drawn from the emergency energy storage and/or the peak output (Pmax) which can be drawn from the emergency energy storage has reached a definable minimum energy value. A process for preparing an emergency energy storage device for operation in which the emergency energy storage is discharged via a discharging device and the heat occurring at the internal resistance (Ri) is used to heat the emergency energy storage device.

Abstract: A method for charging an electric emergency energy storage device (1) comprising the following steps: predicting the energy demand EB of the energy consumer (2), determining the capacitance C of the emergency energy storage device (1) and the internal resistance Ri of the emergency energy storage device (1), calculating a charging voltage UL, whereby the charging voltage UL is calculated in such a way that the energy EC stored in the emergency energy storage device (1) at this charging voltage UL is just enough to meet the predicted energy demand EB, taking into account losses that occur, especially at the internal resistor Ri, and charging or discharging the emergency energy storage device (1) until the calculated charging voltage UL has been reached.
