Provided is a battery module including an electronic component, in which, by improving a structure of the electronic component, a manufacturing cost of the electronic component may be reduced, and an increase in a volume of the electronic component may be suppressed. The battery module may include a voltage measurement circuit electrically connected to battery cells to measure a voltage of the battery cells, the voltage measurement circuit including a main circuit manufactured using a first method, and a fuse electrically connected to the main circuit and manufactured using a second method that is different from the first method.

A power fuse for protecting an electrical load subject to transient load current cycling events in a direct current electrical power system is provided. The power fuse includes at least one fuse element assembly that includes one or more substrates, one or more sets of weak spots, and a conductor. The weak spots are formed on the substrates, and the substrates are longitudinally spaced apart from one another along the conductor. The conductor is separately provided from the substrate and the weak spots. The conductor includes one or more strips of metal having no stamped weak spot openings therein and therefore avoiding thermal-mechanical fatigue strain in the conductor when subjected to the transient load current cycling events. The conductor includes connector sections that are attached to respective ones of the sets of weak spots, and extending sections coupling the connector sections.

The present invention relates to a pattern fuse including a flame retardant coating layer and an opening, the pattern fuse being configured to prevent fire outbreak due to overcurrent generated when a circuit pattern is operated and to designate a breakage position, a flexible printed circuit board including the same, and a battery module including the same, wherein it is possible to prevent fire outbreak even when the pattern fuse is heated to a high temperature as the result of operation of the pattern fuse, and the pattern fuse is broken by fusing at a specific position thereof.
