PROTECTION ELEMENT, AND BATTERY PACK

摘要

PROBLEM TO BE SOLVED: To provide a protection element capable of stopping heat generation of a heating resistor with certainty after all fuse elements are melted even when energized only from a specific energization path.SOLUTION: A protection element is configured to control melting times of a plurality of fuse elements 12a and 12b so that a specific fuse element among the plurality of fuse elements 12a and 12b is melted after other fuse element is melted when energized from a specific energization path to which the specific fuse element is connected.
