Abstract
The present disclosure relates to a fuse device, a battery management system, and a battery pack. A diagnostic current supply circuit is connected to a first fuse element and a second fuse element to allow a diagnostic current to flow in the first and second fuse elements, an ignition circuit is connected to the first fuse element and the second fuse element to allow an ignition current to flow in the first and second fuse elements. The diagnosing by controlling the diagnostic current supply circuit and the igniting by controlling the ignition circuit are independently performed.

A fuse device for diagnosing and igniting a fuse, the fuse device comprising:
- a first fuse element and a second fuse element, each configured to block a current path connected to a battery;
- a diagnostic current supply circuit connected to the first fuse element and the second fuse element through a first node and a second node, respectively, the diagnostic current supply circuit configured to allow a diagnostic current to flow in each of the first fuse element and the second fuse element;
- and
- an ignition circuit connected to the first fuse element and the second fuse element through a first branch path and a second branch path, respectively, each branching off from the first node and the second node, respectively, the ignition circuit configured to allow an ignition current to flow in each of the first fuse element and the second fuse element.
A battery management system comprising:
- a first fuse element and a second fuse element, each configured to block a current path connected to a battery;
- a diagnostic current supply circuit connected to each of the first fuse element and the second fuse element, the diagnostic current supply circuit configured to allow a diagnostic current to flow in each of the first fuse element and the second fuse element;
- an ignition circuit connected to each of the first fuse element and the second fuse element, the ignition circuit configured to allow an ignition current to flow in each of the first fuse element and the second fuse element;
- and
- a processor configured to control the diagnostic current supply circuit and the ignition circuit to independently perform diagnosing of the first fuse element and the second fuse element or perform igniting of the first fuse element and the second fuse element.
