A system for decoupling a HV source from an electric vehicle's electrical system is provided that includes (i) at least one electrical contactor, where the HV source is electrically connected to the vehicle's electrical system when the electrical contactor is in a closed state and not electrically connected to the vehicle's electrical system when the electrical contactor is in an open state; (ii) a supplemental restraint system (SRS) that monitors collision data from a plurality of impact sensors and outputs an activation signal in response to monitored collision data; and (iii) a pyrotechnic switch, where the pyrotechnic switch has a pre-activated first state that provides a conductive path that allows the HV source to be electrically connected to the vehicle's electrical system and an activated second state that severs the conductive path and prevents the HV source from being electrically connected to the vehicle's electrical system.
