Abstract
A solar control system includes a solar unit configured to output electric power generated by a solar panel, a battery configured to be supplied with electric power from the solar unit, a first DDC and a second DDC inserted in parallel between the solar unit and the battery and each configured to control electric power, supplied from the solar unit to the battery, based on a command value, a first sensor configured to detect an output current from the first DDC, and a second sensor configured to detect an output current from the second DDC.
Claims12
A solar control system comprising:
- a solar unit configured to output electric power generated by a solar panel;
- a battery configured to be supplied with electric power from the solar unit;
- a first DC-DC converter and a second DC-DC converter inserted in parallel between the solar unit and the battery and each configured to control electric power, supplied from the solar unit to the battery, based on a command value;
- a first sensor configured to detect a first output current output from the first DC-DC converter;
- and
- a second sensor configured to detect a second output current output from the second DC-DC converter.
A method that is executed by a solar control system that includes a solar unit configured to output electric power generated by a solar panel, a battery configured to be supplied with electric power from the solar unit, a first DC-DC converter and a second DC-DC converter inserted in parallel between the solar unit and the battery and each configured to control electric power, supplied from the solar unit to the battery, based on a command value, a first sensor configured to detect a first output current output from the first DC-DC converter, and a second sensor configured to detect a second output current output from the second DC-DC converter, the method comprising:
- determining whether there is an abnormality in at least one of the first sensor and the second sensor based on a differential value between the first output current and the second output current, when there is an abnormality in the system;
- and
- determining whether there is an abnormality in at least one of the first DC-DC converter and the second DC-DC converter based on a total value of the first output current and the second output current in a state where the command value for setting an output current to zero is issued, when there is an abnormality in the system.
A non-transitory storage medium storing functions that are executed by a computer of a solar control system that includes a solar unit configured to output electric power generated by a solar panel, a battery configured to be supplied with electric power from the solar unit, a first DC-DC converter and a second DC-DC converter inserted in parallel between the solar unit and the battery and each configured to control electric power, supplied from the solar unit to the battery, based on a command value, a first sensor configured to detect a first output current output from the first DC-DC converter, and a second sensor configured to detect a second output current output from the second DC-DC converter, the functions comprising:
- determining whether there is an abnormality in at least one of the first sensor and the second sensor based on a differential value between the first output current and the second output current, when there is an abnormality in the system;
- and
- determining whether there is an abnormality in at least one of the first DC-DC converter and the second DC-DC converter based on a total value of the first output current and the second output current in a state where the command value for setting an output current to zero is issued, when there is an abnormality in the system.
