SYSTEMS AND METHODS FOR DISTRIBUTED BATTERY CIRCUIT ISOLATION VIA PYROTECHNIC DISCONNECT

Abstract

A battery system includes a plurality of battery packs and a battery management system (BMS). The BMS is operably coupled to the plurality of battery packs. The plurality of battery packs includes a first battery pack and a second battery pack. The first battery pack includes a first plurality of battery cells, a first fuse, and first terminals. The second battery pack includes a second plurality of battery cells, a second fuse, second terminals, and a supplementary fuse. The second terminals are electrically connected in parallel with the first terminals. The BMS is configured to monitor operational parameters of the plurality of battery packs; detect a fault condition in at least one of the plurality of battery packs; and initiate actuation of the supplementary fuse in response to the detected fault condition. The supplementary fuse is configured to blow to isolate the second battery pack from the first battery pack.
