Abstract
A voltage sensor includes a drive-sense circuit (DSC) and a reference load. The DSC is operably coupled to a point along a wire that is proximate to a battery terminal. The wire connects the battery terminal to a load. The DSC is configured to generate a signal based on a reference signal that is reference signal is based on an estimate of a voltage at the point along the wire. The DSC is also configured to generate an output signal that corresponds to a difference between the signal and the reference signal and to tune the reference signal until the signal compares favorably to the voltage at the point along the wire. The DSC also is configured to determine the voltage at the point along the wire based on the tuned reference signal. The reference load is operably coupled to the DSC and the point along a wire.
