Apparatuses and methods for electrochemical impedance spectroscopy measurements

A battery measurement system, comprising:

• a plurality of capacitors;
• a plurality of probes each electrically coupled with:
• a corresponding capacitor of the plurality of capacitors;
• and
• a corresponding battery of a plurality of batteries;
• a controller configured to:
• provide an interrogatory current;
• and
• measure, via the plurality of probes and the plurality of capacitors, a plurality of voltages associated with the plurality of batteries in response to the interrogatory current;
• and
• a plurality of sense cables each associated with the corresponding battery of the plurality of batteries, wherein:
• each sense cable of the plurality of sense cables is disposed across the corresponding battery such that the interrogatory current flows in a conduction channel in the corresponding battery in a first direction and in the corresponding cable in a second direction substantially opposite of the first direction, and
• each of the sense cable is disposed substantially parallel to the conduction channel in the corresponding battery such that at least a portion of a first magnetic field generated by the interrogatory current flowing in the conduction channel is cancelled by a second magnetic field generated by the interrogatory current flowing in the sense cable.
