Systems and methods for redundant circuit disconnection in electric vehicles are disclosed. Systems can include a resistive metallic fuse connected within an electrical circuit for a battery or otherwise, an inductor comprising a coil of at least one turn of wire about a longitudinal axis, and an AC power source configured to provide an alternating current across the inductor. The resistive metallic fuse may be disposed within the inductor along the longitudinal axis, and the AC power source may be configured to cause the inductor to induce within the resistive metallic fuse eddy currents of sufficient magnitude to melt or vaporize at least a portion of the resistive metallic fuse disposed therein.
