The present invention refers to a device and a method for measuring isolation resistance of a battery powered systems. The device comprises: a first reference resistance (R01) connectable in series between a positive high-voltage bus (1) and a low-voltage ground connection (5), a second reference resistance (R02) connectable in series between the negative high-voltage bus (2) and the a low-voltage ground connection (5), a first measurement resistance (Rbottom) connected with the low-voltage ground connection (5), a second measurement resistance (Rtop1) connectable in series between the positive high-voltage bus (1), and the first measurement resistance (Rbottom), and a third measurement resistance (Rtop2) connectable in series between the negative high-voltage bus (2), and the first measurement resistance (Rbottom). Isolation resistances (Riso_pos, Riso_neg) are calculated based on voltage measurements at the first measurement resistance (Rbottom), and the mean value of the four high-voltage battery voltage measurements.
