Fusible Link Design for Lithium-Ion 18650 Cells

摘要

Aspects disclosed herein provide a fusible link system and/or method configured to protect an electrical system/circuit, e.g., a battery comprising a plurality of cells, from a current overload. To that end, the fusible link system comprises a conductive substrate and one or more first terminals that electrically connected to the conductive substrate. Each of the one or more first terminals comprises one or more structural properties configured to maintain an electrical connection with the conductive substrate when a current load on the first terminal is less than a predetermined maximum and sever the electrical connection with the conductive substrate when the current load on the first terminal equals or exceeds the predetermined maximum.
