1. A disconnect device configured to operate together with a power storage element including a first electrode and a second electrode, the disconnect device comprising:
a cooling device having a first main surface and a second main surface opposite to the first main surface;
a first insulator having a first surface and a second surface opposite to the first surface, the first surface contacting the first main surface of the cooling device;
a second insulator having a first surface and a second surface opposite to the first surface of the second insulator, the first surface of the second insulator contacting the second main surface of the cooling device;
a first charging relay contacting the second surface of the first insulator, the first charging relay including a first terminal and a second terminal;
a first discharging relay contacting the second surface of the first insulator, and including a first terminal and a second terminal;
a protector contacting the second surface of the second insulator, the protector including a first terminal and a second terminal;
a first power storage terminal configured to be connected to the first electrode of the power storage element;
a second power storage terminal configured to be connected to the second electrode of the power storage element;
a first charging terminal;
a second charging terminal;
a first output terminal;
a second output terminal;
a first conductor connecting the first terminal of the protector to the first power storage terminal;
a second conductor connecting the second terminal of the protector to the first terminal of the first discharging relay;
a third conductor connecting the second terminal of the protector to the first terminal of the first charging relay;
a fourth conductor connecting the second terminal of the first discharging relay to the first output terminal;
a fifth conductor connecting the second terminal of the first charging relay to the first charging terminal;
a sixth conductor connecting the second power storage terminal to the second output terminal; and
a seventh conductor connecting the second power storage terminal to the second charging terminal, wherein
the first charging relay is separated from the first discharging relay via a space between the first charging relay and the first discharging relay, and
at least a part of the protector faces the space across the first insulator, the cooling device, and the second insulator.
