| 摘要 |
The invention relates to a method for error detection during charging of an energy storage system (7) in a vehicle (1), said vehicle (1) comprising an electric machine (3) which is arranged for propulsion of said vehicle (1), said method comprising: requesting (20) a charging pattern from an external power supply (11), by means of a vehicle control unit (8; 13), upon connection (19) of said energy storage system (7) to said external power supply (11); and supplying (22) said charging pattern to said energy storage system (7) by means of an external charging control unit (17) forming part of said external power supply (11). The method furthermore comprises: providing (21) a predetermined modulation of the requested charging pattern; evaluating (23) whether the charging pattern supplied to said energy storage system (7) comprises said predetermined modulation; and, if this is not the case, indicating (25) that the charging of said energy storage system (7) is erroneous. The invention also relates to an arrangement for error detection during charging of an energy storage system (7), and a vehicle (1) comprising an electric machine (3) and having such an arrangement. |
