Abstract
A power supply system for moving body includes a first power source, a first current path, a second power source, a second current path. The first power source supplies electric power to a redundant load. The first current path connects the first power source and the redundant load. The second power source supplies electric power to the redundant load. The second current path connects the second power source and the redundant load.
Claims8
A power supply system for moving body comprising:
- a first power source configured to supply electric power to a redundant load;
- a first current path configured to connect the first power source and the redundant load;
- a signal generation unit connected to the first current path and configured to generate a test signal;
- a second power source configured to supply electric power to the redundant load;
- a second current path configured to connect the second power source and the redundant load;
- a signal detection unit connected to the second current path and configured to detect presence or absence of the test signal;
- and
- a control unit configured to execute a continuity test in a state where the redundant load is connected to the first current path and the second current path, wherein,
- in the continuity test, the control unit determines whether the first current path and the second current path are conducted with each other based on a detection result of the test signal in the signal detection unit.
