Power supply monitoring apparatus for vehicle

摘要

The state of the power supplied by power supply outlets (A1 - Am) is monitored. When an overcurrent condition is detected and exceeds a preset time a command is sent to the cut-off device to interrupt the current. When an idle-up command circuit detects an increase in a supplied current, an idle-up command is issued. The monitor employs a cut-of device (11), current detectors (B1 -Bm) and overcurrent detectors (C1 - Cm). The cut-off device is a relay in the supply from the battery (1) and is controlled by a drive circuit (17).
