Positioning and correction of current sensing devices

A method of sensing current, comprising:

• measuring a current through a first conductor of a conductor assembly by a current sensor disposed proximate to the first conductor, to generate a first current measurement;
• and
• receiving the first current measurement at a correction module and performing a correction method, the correction method including at least one of:
• determining a frequency of the first current measurement, and applying a gain correction factor to the first current measurement, the gain correction factor based on pre-characterization data relating a gain of a reference current sensor to current frequency, wherein the pre-characterization data is acquired based on at least one of measuring and simulating a reference current through the reference current sensor at a plurality of frequencies, and deriving a reference gain distribution;
• and
• determining a first phase of the first current measurement, acquiring a second current measurement of a second conductor of the conductor assembly, determining a second phase of the second current measurement, and applying a current adjustment to the first current measurement based on a temporal relationship between the first phase and the second phase.

A vehicle system comprising:
