Claim 13:
14. A method of operating protection system for a battery system arranged to provide power to a load, the method comprising:
selectively opening at least one contactor to isolate the battery system from the load in response to a sensed current being (i) greater than a first threshold and (ii) within a first current range;
selectively blowing at least one fuse connected between a first terminal and a second terminal of the battery system to isolate the battery system from the load in response to the sensed current being (i) greater than a second threshold that is greater than the first threshold and (ii) within a second current range that is greater than and offset from the first current range; and
selectively forming a short circuit between the first terminal and the second terminal in response to the sensed current being (i) greater than the first threshold, (ii) less than the second threshold, and (iii) within a coverage gap region between the first current range and the second current range.
