Abstract
A power supply system includes: a first power supply circuit for supplying, to a first load device, direct current electric power output from a first power generation device; and a second power supply circuit for supplying, to a second load device, direct current electric power output from a second power generation device. In a case where the electric power output from the second power generation device is supplied to the first load device, a control device connects the first power supply circuit and the second power supply circuit to each other after suppressing the power consumption of the first load device and increasing the power consumption of the second load device.
Claims6
A power supply system comprising:
- a first power supply circuit configured to supply, to a first load device, electric power output from a first power generation device, the electric power being direct current electric power;
- a first power storage device connected to the first power supply circuit in parallel with the first power generation device;
- a second power supply circuit configured to supply, to a second load device, electric power output from a second power generation device, the electric power being direct current electric power;
- a second power storage device connected to the second power supply circuit in parallel with the second power generation device;
- a first connection circuit including a first connection device configured to connect the first power supply circuit and the second power supply circuit to each other;
- and
- a control device including one or more processors that execute computer-executable instructions stored in a memory, wherein the one or more processors execute the computer-executable instructions to cause the control device to execute, on the first connection device, first connection control for connecting the first power supply circuit and the second power supply circuit to each other via the first connection circuit,
- wherein, in a case where the electric power output from the second power generation device is required to be supplied to the first load device and a difference between a voltage of the first power supply circuit and a voltage of the second power supply circuit is equal to or greater than a first voltage threshold determined in advance, the one or more processors cause the control device to execute the first connection control on the first connection device after executing first power consumption suppression control on the first load device and executing first power consumption increase control on the second load device, the first power consumption suppression control being control for suppressing power consumption of the first load device to suppress a decrease in an output voltage of the first power storage device, the first power consumption increase control being control for increasing power consumption of the second load device to promote a decrease in an output voltage of the second power storage device.
