METHOD FOR CHECKING THE PLAUSIBILITY OF INSULATION MONITORING OF A HIGH-VOLTAGE SYSTEM OF AN ELECTRIC VEHICLE DURING THE CHARGING OF A TRACTION BATTERY OF THE ELECTRIC VEHICLE

A method is provided for checking the plausibility of insulation monitoring of a high-voltage system () of an electric vehicle during the charging of a traction battery of the electric vehicle. The electrical insulation of the high-voltage system () is monitored by an insulation monitoring device (), and a check is carried out cyclically to determine whether a further insulation monitoring device is active on a high-voltage bus of the high-voltage system ().
