METHOD FOR DETERMINING THE ABSENCE OF VOLTAGE IN AN ELECTRICAL HIGH-VOLTAGE SYSTEM, AND ELECTRICAL HIGH-VOLTAGE SYSTEM

摘要

The invention relates to a method for determining the absence of voltage in an electrical high-voltage system (1), in particular in an electric or hybrid vehicle, by means of at least two control units (3-5) in the high-voltage system (1) and at least one display unit (14, 16), wherein the control units (3-5) detect the voltage in the high-voltage system (1) independently of one another, wherein an absence of voltage is displayed on the display unit (14, 16) only if both control units (3-5) detect a voltage below a threshold value. The invention further relates to an electrical high-voltage system (1).
