By pack external short circuit we mean an electrical short circuit, a very low resistance path between the positive and negative terminals of the pack.
The purpose of this test is to simulate an abuse condition for the pack where it is mishandled or misused.
The maximum current could be limited by a fuse, contactors or pyro fuse. Legislation should be reviewed for the application to understand the short circuit test, in addition the pack design guidance on ensuring the safe operation of the pack should be adhered to.
Needs review: this page has no References section and doesn’t name the specific standards (e.g. UN 38.3, ISO 6469-4, GB 38031) or pass/fail criteria that govern pack-level external short circuit testing. Needs a subject-matter expansion pass rather than an automated rewrite.
