PROBLEM TO BE SOLVED: To simply determine a severity of a failure when a failure occurs in a power supply unit.SOLUTION: A power supply management device 10 includes: a plurality of module state detection means 102 for detecting respective working state information of a plurality of modules 20; and a failure detection means 104 for detecting each failure in the respective modules 20. A failure detection means 202 and a module state detection means 204 are connected through a first communication line L1 that is a communication line for CAN communication, and a second communication line L2 that is a numbered communication line. The failure detection means 202, on detecting a communication failure in the first communication line L1, transmits a signal to the second communication line L2, to determine a severity of the failure on the basis of a response to the transmitted signal. |
