A method for ascertaining an inner resistance of a supply network for supplying energy to an occupant protection system of a vehicle. The occupant protection system includes a charging unit connected to the supply network using a primary interface and to an energy buffer store using a secondary interface for the temporary storage of energy for activating occupant protection devices system and for supplying the system after being separated from the supply network. The method includes impressing a first charge current value at the secondary interface, and a first current/voltage at the primary interface during the impression. Further, a second, different, charge current value is impressed at the secondary interface. The method also includes determining a second current/voltage at the primary interface during the impression, and ascertaining the inner resistance of the supply network, using the detected first current and second current and/or the first voltage and the second voltage.
