<p>PROBLEM TO BE SOLVED: To provide a power monitor for vehicle capable of making a feed socket unavailable in stopping an engine, thereby preventing battery consumption in stopping the engine. SOLUTION: This power monitor for vehicle monitors a power supply condition when power from the battery 1 is supplied to an electrical apparatus through feed sockets A1-Am provided on a vehicle, and is provided with a breaker 11 disposed on a current-carrying path D, an engine stop detecting circuit 16 detecting the stop of the engine based on the L-signal of a regulator IC19 and cutting off the breaker 11 through a driving circuit 17, overcurrent detecting circuits C1-Cm detecting the overcurrent based on the detected values of current detecting circuits B1-Bm and cutting off the breaker 11, an idle-up command circuit 13 for detecting an increase in supply current and indicating idle-up, and a low voltage detecting circuit 15 for detecting reduction in the output voltage of the battery 1 and cutting off the breaker 11.</p> |
