To provide a power supply controller capable of protecting a storage battery from excessive electric power generation and a power supply system comprising the power supply controller.SOLUTION: An power supply system comprises: a dynamo-electric generator that generates electric power with power of an engine; a storage battery to which generated electric power of the dynamo-electric generator is supplied; a load to which electric power is supplied from the dynamo-electric generator and the storage battery; and a switch which is provided on an electric passage connecting the dynamo-electric generator, the storage battery, and the load to each other, and switches an electric connection state of the dynamo-electric generator, the storage battery, and the load each other. A power supply passage serving as the electric passage connecting the dynamo-electric generator and the storage battery under a power generation state where the dynamo-electric generator is generating electric power, comprises: an abnormality determination unit that determines whether the passage is in an abnormal state in which the power supply passage is an abnormal passage where a predetermined or greater generated electric power is supplied; and a load control unit that controls an operation state of the load so as to increase power consumption in the load when the abnormal state is determined.SELECTED DRAWING: Figure 1
