Patent Images
1. A method for determining the residual travel duration of a submarine, the method comprising:
- providing a submarine with a pressure hull and an electric battery inside the pressure hull;
firstly, for at least one certain travel situation of the submarine, carrying out a reference journey through water, with which the power consumption of the submarine is detected, and stored as a situation-dependent consumption profile; and
later, for the same travel situation of the submarine, predicting the residual travel duration or a residual capacity of a battery after a predefined travel duration on the basis of the stored consumption profile and the current battery data.

Abstract
A method as well as a device are provided for determining the residual travel duration of a submarine, with which firstly for at least one certain travel situation a reference journey is carried out with which the power consumption of the submarine is detected as stored as a dependent-dependent consumption profile. Later, for the same travel situation, the residual travel duration or a residual capacity of a battery given a predefined travel duration is determined on the basis of the stored consumption profile and the current battery data.
