Abstract

An insulation verification system (10) for a motor vehicle (1) provided with a high-voltage battery (5) connected to a high-voltage bus (12) is described, involving: a first insulation monitoring device (20), arranged inside the high-voltage battery (5), and managed and controlled by a corresponding BMS management module (9) of the high-voltage battery (5); a second insulation monitoring device (21), arranged outside the high-voltage battery (5); an insulation control unit (24), external to the high-voltage battery (5) and operatively coupled to the second insulation monitoring device (21) to manage its operation. The insulation control unit (24) implements a control logic of the insulation verification system (10) for verification of the electrical insulation of the high-voltage bus (12) involving an interaction, with cooperation without mutual interference, between the first and second insulation monitoring devices (20, 21).
