Abstract: A computer-implemented method and a control device for triggering a high level communication between an electric vehicle and a charging station is provides. The electric vehicle includes a control unit with a first microcontroller and a second microcontroller. The method includes operating only the second microcontroller of the control unit for detecting a wake-up signal coming from a possible connection of the electric vehicle to a charging station and keeping the first microcontroller deactivated. The method also includes connecting the electric vehicle to the charging station, whereby at least one wake-up signal is sent to the control unit. Additionally, the method includes detecting the wake-up signal coming from the connection of the electric vehicle to the charging station with the second microcontroller. The method also includes activating the first microcontroller using the second microcontroller when the wake-up signal is detected.
