Document Type and Number:
Japanese Patent JP2020167882
Kind Code:
A
Abstract:
To provide a power distribution device capable of supplying power to a load depending on a peripheral environment.SOLUTION: A power distribution device 50 for distributing power of a power supply 1 to a plurality of loads 21 to 23 comprises: a fuse unit 20 including a semiconductor switch 2a connectable with the power supply 1; a distribution unit 10 including a plurality of semiconductor switches 11a, 12a, 13a corresponding to the plurality of loads 21, 22, 23; a wire harness 3 connecting the fuse unit 20 with the distribution unit 10; a control unit 40 for controlling ON/OFF of the semiconductor switches 11a, 12a, 13a; a current sensor 2c for detecting current flowing through the wire harness 3; and voltage sensors 2d, 11d for detecting voltage at both ends of the wire harness. The control unit 40 determines a state of the wire harness 3 on the basis of detection results of the current sensor and the voltage sensors and, depending on the state of the wire harness 3, controls the semiconductor switches 11a, 12a, 13a.SELECTED DRAWING: Figure 1
