1. A method for planning the journey of a battery powered vehicle, the method comprising the steps of:
- obtaining battery characteristics for a battery, said battery characteristics including battery capacity indicating an amount of energy that can be stored in the battery, said battery capacity varying depending on how the battery is charged, said battery characteristics including an initial energy reserve of the battery;
receiving a destination for the vehicle;
determining a travel profile for the vehicle to reach the destination, the profile having a plurality of discharging cycles which supply energy to operate the vehicle as the vehicle travels to its destination, the discharging cycles decreasing the energy reserve of the battery, the travel profile having a plurality of charging cycles for increasing the energy reserve of the battery;
determining how much each of the discharging cycles will reduce the energy reserve of the battery;
determining how much each of the charging cycles will increase the energy reserve of the battery, and how each of the charging cycles will affect the battery capacitydetermining how each change in battery capacity from a previous charging cycle will affect the increasing of the energy reserve of future charging cycles;
predicting a future energy reserve of the battery at the destination of the vehicle based on the plurality of discharging cycles, the plurality of charging cycles and the changes in battery capacity.

Abstract
A method and system for planning the journey of a submarine are provided using at least one electrical drive with a battery for energy supply and a charging device for the battery. For a selected future point in time, the remaining available energy reserve of the battery is predicted on the basis of the travel duration up to this point in time, of at least of one consumption profile selected for the travel duration, and of the type and duration of the charging cycles of the battery being effected up to this point in time.
