1. A method for discharging a capacitor,
wherein an active discharge circuit is connected in parallel with the capacitor,
wherein an interface provides a signal connection between a message-based communication system and the active discharge circuit,
wherein the interface comprises at least one input for receiving messages from the message-based communication system,
wherein the interface comprises a wake-up functionality,
wherein the at least one input comprises an input for the wake-up functionality,
wherein 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, enabling a discharge of the capacitor.
