Claim 0:
1. A protection system for a battery system arranged to provide power to a load, the protection system comprising:
a battery control module configured to selectively open 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;
at least one fuse connected between a first terminal and a second terminal of the battery system, wherein the at least one fuse is configured to open 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
an auxiliary protection module configured to selectively form 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.
