    • A device and a method for automatic monitoring of the insulation resistance of a battery of a power supply, wherein the battery comprises a plurality of battery cells, a metal enclosure and an electrical insulation between the enclosure and the battery cells. The monitoring device comprises means for measuring 1) a first voltage between the enclosure and one of the battery poles, by means of a first load circuit connected to said battery pole and to the enclosure, 2) a second voltage between the enclosure and one of the battery poles, by means of a second load circuit connected to both poles and to the enclosure, and 3) the voltage between the battery poles. The device further comprises means for switching between the two load circuits. The insulation resistance, calculated- from the measured voltages, may be compared to a preset value representing an insulation failure decision limit.
