Title: SWITCH DEVICE FOR ON-VEHICLE POWER SUPPLY AND ON-VEHICLE POWER SUPPLY SYSTEM
Abstract:
Provided is a switch device which is for an on-vehicle power supply and can quickly perform a switch control. This switch device is provided with a first switch, a second switch, a ground fault information detecting unit, and a single control circuit. The first switch is connected between a first power storage device and a load. The second switch is connected between a second power storage device and the load. The ground fault information detecting unit detects an electrical detection value for determining whether a ground fault occurs on the first power storage device side and the second power storage device side. The control circuit is connected to the ground fault information detecting unit, a first switch control terminal, and a second switch control terminal, and controls the first switch and the second switch on the basis of the detected value from the ground fault information detecting unit.
