Continuous circuit and fuse protection in high voltage applications exposed to chemically harsh environments

A method of providing protection for a voltage-sensing circuit of an automotive propulsion system battery pack, the method comprising:

• disposing the voltage-sensing circuit on a substrate such that the voltage-sensing circuit is cooperative with at least one battery cell, the voltage-sensing circuit comprising a fuse and a voltage trace, the fuse being surface mounted, the voltage trace being electrically coupled to the fuse, the voltage-sensing circuit configured to provide indicia of an electrical condition of the at least one battery cell;
• coating a precursor onto the fuse such that the precursor substantially covers all exposed portions of the fuse, the precursor configured to substantially remain as coated over the exposed portions of the fuse during an entirety of the coating;
• and
• curing the precursor to thereby form an encapsulant, the encapsulant being substantially conformal around the fuse, the encapsulant being environmentally resistant material such that the fuse is isolated from an ambient environment during normal battery pack operation and after the battery pack is compromised.
