ABSTRACT:
A vehicular use power feed apparatus comprising a battery and a plurality of power distribution units connected in a loop via power feed lines. Each power distribution unit has a current monitoring circuit, a current amount determination circuit, and a current direction determination circuit, detects the direction of current and magnitude of current flowing through the power feed line, and thereby detects an occurrence of a short-circuit. A control unit exchanges information regarding occurrence of short-circuits with adjoining power distribution units via a multiplex signal transmission unit so as to pinpoint the trouble point. The control unit operates the relay switch circuits on the two sides to break the connection so as to isolate the trouble point in cooperation with the control unit of the adjoining power distribution unit. The other relay switch circuit is operated to establish a connection so as to establish a new power feed line.
