Abstract: An electronic component module according to the present disclosure includes a fuse, a relay, a first conductor, a first connecting conductor, a second conductor, a second connecting conductor, and a third conductor. The first conductor, the second conductor, and the third conductor are arranged in the order of the third conductor, the second conductor, and the first conductor in a first direction. A first fuse terminal is connected to a plate-shaped portion of the first connecting conductor. A second fuse terminal is connected to a plate-shaped portion of the second connecting conductor. A first relay terminal is connected to an end of the second conductor that is located in a direction opposite to the first direction. A second relay terminal is connected to an end of the third conductor that is located in the first direction.

Abstract: A fuse is at least partially located between a first load relay and a first charging relay, and an electric current detector is at least partially located between a second load relay and a second charging relay. The electric current detector is in contact with an insulating layer. As viewed from the side, the fuse is located below the electric current detector. The fuse is not in contact with the electric current detector.

Abstract: 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.
