The invention relates to a method for controlling an energy storage device (10) of a mild hybrid motor vehicle, wherein the energy storage device (10) has an overall capacity, wherein a state-of-charge control device (32) of the energy storage device (10) sets a state of charge of the energy storage device (10) between an upper threshold value (oSW) and a lower threshold value (uSW) for a target state-of-charge range (18) of the energy storage device (10), wherein during at least one journey at least one charging process (34) and one discharging process (36) are monitored with respect to quantities of energy which are exchanged with the energy storage device (10) and quantities of energy which are to be expected with a predefinable probability for future charging processes and discharging processes are determined, and wherein the upper threshold value (oSW) and the lower threshold value (uSW) for the target state-of-charge range (18) of the energy storage device (10) are defined on the basis of the determinations in step b). The invention also relates to a corresponding state-of-charge control device (32) for a mild hybrid motor vehicle.
