A vehicular power supply system includes a sensor unit that detects a battery state of a storage battery and a control unit that performs instruction to perform energization and interruption thereof between the storage battery and the electrical load based on the battery state. The sensor unit includes a detection unit that detects the battery state of the storage battery, a switch drive unit that performs drive control of a switch unit provided between the storage battery and the electrical load, and a control unit that controls the switch drive unit. The control unit switches between the energization and interruption thereof between the storage battery and the electrical load. If determining an abnormality, the control unit determines whether to maintain the energization between the storage battery and the electrical load based on the battery state and switches between the energization and interruption thereof based on the determination.
