PROBLEM TO BE SOLVED: To provide a power supply management device capable of identifying abnormalities of each module with a simple configuration.SOLUTION: When a voltage of DC 12 volts is supplied to a numbering voltage input terminal 501 of a CMU 301 to set resistance values of resistance elements 511 and 512 of a numbering circuit of each CMU to the same resistance value, a numbering voltage at a connection point P between the resistance element 511 and the resistance element 512 becomes 6 volts. The voltage of 6 volts is supplied from the CMU 301 to the numbering voltage input terminal 501 of a CMU 302, and the numbering voltage of the CMU 302 becomes 3 volts. In this way, the numbering voltage of the CMU on a connection downstream side is set sequentially in stages. In addition, a range of a voltage level of the numbering voltage and an identification number are prescribed by a numbering table 552, and the identification number corresponding to a voltage level of the numbering voltage of the CMU is given to the CMU, and the identification number is sequentially numbered from the CMU on the connection most upstream side to the CMU on the connection downstream side with a simple configuration. Thereby, abnormalities in each module of a motor power supply part can be identified for each module. |
