Power supply system and moving object
A power supply system includes a power storage device, a power supply circuit for supplying DC power from the power storage device to a load device, and a containment member for accommodating the power storage device. The power supply circuit includes a positive wire and a negative wire, a first switch provided on the positive wire, and a second switch provided on the negative wire. One of the first switch or the second switch is disposed in the interior of the containment member, and another one of the first switch or the second switch is disposed on the exterior of the containment member.
1 . A power supply system comprising:
a power storage device;
a power supply circuit configured to supply direct current power from the power storage device to a load device; and
a containment member configured to accommodate the power storage device,
wherein the power supply circuit includes:
a positive wire and a negative wire;
a first switch provided on the positive wire; and
a second switch provided on the negative wire, and
one of the first switch or the second switch is disposed in an interior of the containment member, and another one of the first switch or the second switch is disposed on an exterior of the containment member,
further comprising
a control unit configured to control an operation of each of the first switch and the second switch, wherein
the control unit turns off the another one of the first switch or the second switch disposed on the exterior of the containment member in a case where an abnormality in the interior of the containment member is detected.
2 . The power supply system according to claim 1 , wherein
the power supply circuit includes a precharge circuit configured to precharge a smoothing capacitor provided in the load device, and
the precharge circuit is disposed on the exterior of the containment member.
3 . The power supply system according to claim 1 , further comprising
a power generation device connected to the power supply circuit in parallel with the power storage device.
4 . The power supply system according to claim 1 , wherein
the control unit is disposed on the exterior of the containment member.
5 . A moving object comprising the power supply system according to claim 1 .
6 . The power supply system according to claim 1 , wherein
in the interior of the containment member, the one switch is provided only on one of the positive wire or the negative wire, and
on the exterior of the containment member, the another switch is provided only on the other of the positive wire or the negative wire.
7 . The power supply system according to claim 1 , wherein
the containment member is made from material that has heat resistance.
8 . The power supply system according to claim 1 , wherein
the power supply circuit includes a precharge circuit configured to precharge a smoothing capacitor provided in the load device, and
the precharge circuit is disposed in the interior of the containment member.
