More Information
Summary:A battery pack, an integrated device for sensing individual battery voltages in a battery pack and protecting the battery pack in the event of a circuit-breaking event, and a method of forming an integrated voltage-sensing circuit for use in a battery-powered automobile propulsion system. The battery pack includes numerous voltage sensing circuits with patterned sense line trace fuses and an encapsulant formed around each of the fuses. The encapsulant is robust enough to provide environmental isolation of the patterned fuse such that the tendency of the fuse to form short-circuit connections to adjacent circuits is avoided under both normal battery pack operation and after a circuit-breaking episode where the fuse blows.
