Kind Code:
A1
Abstract:
According to the present invention, power is fed to an electrical load of a vehicle even in the event of failure of one on-board power supply. This power feeding relay circuit relays power fed from a sub-battery to a plurality of loads to which power is fed from a main battery provided in a vehicle. The power feeding relay circuit is provided with: a plurality of switches provided so as to correspond to the respective loads; power receiving lines which connect the switches and the sub-battery; a plurality of power feeding lines which are provided so as to correspond to the respective loads, and which feed power from the respective switches to the corresponding loads; and a control circuit which turns on the switches in the case when the voltage of the main battery is lower than a prescribed first threshold value.
