The method furthermore includes providing a predetermined modulation of the requested charging pattern; evaluating whether the charging pattern supplied to the energy storage system includes the predetermined modulation; and, if this is not the case, indicating that the charging of the energy storage system is erroneous. An arrangement for error detection during charging of an energy storage system, and a vehicle including an electric machine and having such an arrangement are also provided.
