1. A method for controlling a lock state of a charging cable connected to a power inlet of an electrical vehicle, the vehicle comprising an energy storage device electrically connected to the power inlet, a lock unit for locking the charging cable to the power inlet, and a control unit for controlling a lock state of the lock unit, the method comprising:
- in the control unit, receiving an unlock request for unlocking a charging cable locked to the power inlet by the lock unit;
breaking an electrical connection between the charging cable and the energy storage device such that charging is aborted;
unlocking the cable from the power inlet within a first predetermined time after receiving the unlock request; and
,if the cable is not removed from the power inlet within a second predetermined time after receiving the unlock request, locking the cable to the power inlet and forming an electrical connection between the charging cable and the energy storage device to restart charging.
