Abstract

A method is provided for checking the plausibility of insulation monitoring of a high-voltage system (100) of an electric vehicle during the charging of a traction battery of the electric vehicle. The electrical insulation of the high-voltage system (100) is monitored by an insulation monitoring device (101), 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 (100).
