Zusammenfassung:	A method for discharging a capacitor. An active discharge circuit is connected in parallel with the capacitor. An interface provides a signal connection between a message-based communication system and the active discharge circuit. The interface comprises at least one input for receiving messages from the message-based communication system. The interface comprises a wake-up functionality. The at least one input comprises an input for the wake-up functionality. The method comprises: receiving at the input for the wake-up functionality a disable discharge command message of said messages for the disabling of the discharge of the capacitor, wherein upon cessation of the disable discharge command message the discharge of the capacitor is enabled. An apparatus for the discharge of a capacitor, wherein the apparatus comprises the interface and the active discharge circuit connectable in parallel with the capacitor.
