Power supply system and moving object

An electrical power supply system, comprising:

• a first electrical power transmission bus configured to supply, to a first load device, a direct current electrical power output from an electrical power generating device and a direct current electrical power output from a first electrical power storage device configured to be disposed in parallel with the electrical power generating device;
• a first electrical current sensor and a second electrical current sensor each configured to detect an electrical current flowing through a first connection circuit configured to connect the first electrical power storage device and the first electrical power transmission bus;
• a third electrical current sensor configured to detect an electrical current flowing through the first electrical power transmission bus, at a location closer to the electrical power generating device than is a connected location between the first electrical power transmission bus and the first connection circuit;
• a fourth electrical current sensor configured to detect an electrical current flowing through the first electrical power transmission bus, at a location closer to the first load device than is the connected location between the first electrical power transmission bus and the first connection circuit;
• a first electrical power storage control device including one or more processors that execute computer-executable instructions stored in a memory;
• and
• a management control device including one or more processors that execute computer-executable instructions stored in a memory, and configured to manage the first electrical power storage control device,
• wherein the one or more processors execute the computer-executable instructions to cause the first electrical power storage control device to acquire first electrical current information indicating the electrical current detected by the first electrical current sensor, and second electrical current information indicating the electrical current detected by the second electrical current sensor, and
• the one or more processors execute the computer-executable instructions to cause the management control device to:
• acquire the first electrical current information and the second electrical current information from the first electrical power storage control device, and acquire third electrical current information indicating the electrical current detected by the third electrical current sensor, and fourth electrical current information indicating the electrical current detected by the fourth electrical current sensor;
• and
• determine whether or not the first electrical current sensor has malfunctioned based on a comparison between the first electrical current information, the second electrical current information, the third electrical current information, and the fourth electrical current information.
