Method and arrangement for error detection during charging of an energy storage system
First Claim
1. A method for error detection during charging of an energy storage system in a vehicle, the vehicle comprising an electric machine which is arranged for propulsion of the vehicle, the method comprising:
- requesting a charging pattern from an external power supply, by means of a vehicle control unit, upon connection of the energy storage system to the external power supply;
supplying the charging pattern to the energy storage system by means of an external charging unit forming part of the external power supply;
providing a predetermined modulation of the requested charging pattern;
evaluating whether the charging pattern supplied to the energy storage system comprises the predetermined modulation; and
,indicating that the charging of the energy storage system is erroneous when the charging pattern does not comprise the predetermined modulation.

Abstract
A method for error detection during charging of an energy storage system in a vehicle is provided, the vehicle including an electric machine which is arranged for propulsion of the vehicle. The method includes requesting a charging pattern from an external power supply, by a vehicle control unit, upon connection of the energy storage system to the external power supply; and supplying the charging pattern to the energy storage system by an external charging control unit forming part of the external power supply. 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.
