Abstract:
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 (R 01 ) connectable in series between a positive high-voltage bus ( 1 ) and a low-voltage ground connection ( 5 ), a second reference resistance (R 02 ) 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 (Rtop 1 ) connectable in series between the positive high-voltage bus ( 1 ), and the first measurement resistance (Rbottom), and a third measurement resistance (Rtop 2 ) 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.

Claim (Index 13):
The device according to  claim 12 , wherein the control module is additionally adapted to set the device in a first measurement position where the first switch is open, the second switch is open, the third switch is closed, and the fourth switch is open, and wherein the calculating module is adapted to measure voltage at the first measuring resistance and voltage at the battery when in the first measurement position.
