<p>PROBLEM TO BE SOLVED: To provide a power supply control system which can prevent reliably the battery exhaustion when the communication between a control device and a control circuit is disrupted.SOLUTION: In a power supply control system 1, the transmitting unit 61 of a control device 6 transmits control signals which indicate operating or stopping of each of loads 40 and 41 to a control circuit 52. The control circuit 52 controls individually the power supply to the loads 40 and 41 from a battery 3 on the basis of the control signal transmitted from the transmitting unit 61. The control unit 65 of the control device 6 detects disruption of the communication between the transmitting unit 61 and the control circuit 52. An output unit 63 outputs the interception indication which indicates interception of power supply to the loads 40 and 41 to the control circuit 52, when the control part 65 detects the disruption of communication. The control circuits 52 to which the interception indication is inputted intercepts the power supply to the loads 40 and 41 by turning both FET 50 and 51 to off.</p> |
