<p>PROBLEM TO BE SOLVED: To provide a power supply monitoring device for an automobile where a user can confirm performing of power managing operation of a feeding socket or an idle-up or the like and properly correspond to it. SOLUTION: This power supply monitoring device for an automobile is provided with a circuit breaker 11 cutting off the feeding sockets A1 to Am, an engine stoppage detecting circuit 16 detecting an engine stoppage on the basis of an L signal of a regulator IC 21 and having the circuit breaker 1 perform a cut off via a driving circuit 17, overcurrent detecting circuits C1 to Cm detecting an overcurrent on the basis of detected values of current detecting circuits B1 to Bm and having the circuit breaker 11 perform a cut off, an idle-up command circuit 13 detecting an increase of feeding current for instructing an idle-up, a low voltage detecting circuit 15 detecting a decline of output voltage of a battery 1 for having the circuit breaker 11 perform a cut off, and a display control part individually switching lighting states of light emitting elements of each color of a display part on the basis of an existence of a cut off of the circuit breaker 11, an existence of an idle-up, or the like.</p> |
