| Zusammenfassung: | A protection system includes: a first positive terminal; a second positive terminal; a first relay configured to be opened and closed by contact and separation of a first contact portion and a second contact portion; and a fuse. The first relay and the fuse are connected in series between the first positive terminal and the second positive terminal, and when an electric current exceeding a threshold current flows to the first relay, the first contact portion and the second contact portion are separated in the first relay at a first time, and when the first contact portion and the second contact portion are separated, an arc discharge occurs between the first contact portion and the second contact portion, an arc discharge occurs between the first electrode and the second electrode of the fuse at a second time, the arc discharge occurs at both of the first relay and the fuse and a difference in potential between the first electrode and the second electrode of the fuse increases during a period between the second time and a third time, and the first positive terminal and the second positive terminal are disconnected at a fourth time. |
