Quick battery disconnect system for high current circuits

Abstract:

A circuit protection system is provided herein that minimizes the disconnection time of a circuit while protecting other electrical components. Some configurations comprise a set of parallel circuit interruption devices, each connected in series with respective fuses. A control device sets a state of the circuit interruption device based on a current of the circuit. Under certain current loads, the circuit is interrupted without causing a fuse to blow. Under other current loads, the circuit is interrupted by having one or more fuses blow.
