Abstract
A system for making high voltage measurements to measure a voltage of a battery pack and detect of an isolation fault. The system includes a first resistive divider comprising at least a first resistive element and a second resistive element. The system also includes a second resistive divider comprising the second resistive element and a third resistive element. The system also includes a plurality of switches comprising a first switch and a second switch coupled between the second resistive element and the battery pack. The system further includes a controller configured to control the plurality of switches to operate in first mode to measure the voltage of the battery pack based on a voltage produced by the first resistive divider, and to control the plurality of switches to operate in at least a second mode to detect an isolation fault based on a voltage produced by the second resistive divider.
