Abstract: A current fuse device and a battery assembly comprising the same. The current fuse device (100, 200) comprises an insulating box(1) having a cavity(10), a first conductor(21) with a first inner end(211), a second conductor(22) with a second inner end(221) and at least one elastic member(31,32) provided on at least one of the first conductor(21) and the second conductor(22) inside the cavity(10). The elastic member(31,32) forms electrical connection with the first and second inner ends(211, 221) simultaneously. The elastic member(31,32) may have elastic potential energy to break the electrical connection during short-circuiting.
