Abstract
A power supply circuit includes a first power transmission bus that supplies direct current power from a power generation device to a first load device, a first disconnection device including a first disconnection unit disposed in a positive wire of the first power transmission bus, a first reverse flow prevention device having a first reverse flow prevention element disposed in the positive wire of the first power transmission bus, a charging circuit that is connected to the first power transmission bus between the first disconnection device and the first reverse flow prevention device and to which an external charging device can be connected, and a second disconnection device having a second disconnection unit provided in a negative wire of the charging circuit.
Claims4
A power supply circuit comprising:
- a first power transmission bus configured to supply, to a first load device, direct current power output from a power generation device and direct current power output from a first power storage device provided in parallel with the power generation device;
- a first disconnection device configured to disconnect the power generation device from the first power transmission bus by a first disconnection unit disposed in only one of a pair of wires composed of a positive wire and a negative wire of the first power transmission bus;
- a first reverse flow prevention device configured to prevent power from being supplied from the first power storage device to the first power generation device by a first reverse flow prevention element disposed in only the one of the pair of wires of the first power transmission bus;
- a charging circuit having one end connected to the first power transmission bus at a position between the first disconnection device and the first reverse flow prevention device and another end connected to a charging port connectable to an external charging device;
- and
- a second disconnection device configured to disconnect the charging port from the first power transmission bus by a second disconnection unit disposed in only one of a pair of wires composed of a positive wire and a negative wire of the charging circuit, wherein
- the one of the pair of wires of the charging circuit in which the second disconnection unit is disposed is connected to another of the pair of wires of the first power transmission bus that is different from the one of the pair of wires of the first power transmission bus in which the first disconnection unit and the first reverse flow prevention element are disposed.
