Abstract
A system includes a processing device and a measurement circuit coupled to the processing device. The system further includes an auxiliary voltage supply. The processing device and the measurement circuit are powered by the auxiliary voltage supply. The measurement circuit is to apply a test voltage to a first resistor and measure a voltage drop over the first resistor. The processing device is to determine, based on at least the voltage drop, an isolation resistance value between a chassis ground node and at least one of a battery pack or a battery link of a power system.
