Abstract:
PROBLEM TO BE SOLVED: To provide a switch device for an on-vehicle power source capable of quickly controlling a switch.SOLUTION: A switch device 3 comprises switches 31, 32, a ground fault information detection unit 35, and a single control circuit 34. The switch 31 is connected between a power storage device 1 and a load 4. The switch 32 is connected between a power storage device 2 and the load 4. The ground fault information detection unit 35 detects an electric detection value for determining presence or absence of occurrence of a ground fault on the power storage device 1 side and a ground fault on the power storage device 2 side. The control circuit 34 is connected to the ground fault information detection unit 35 and control ends of the switches 31, 32 and controls the switches 31, 32 based on the detection value of the ground fault information detection unit 35.SELECTED DRAWING: Figure 1
