A power supply control system includes at least two power supply devices. Each of the at least two power supply devices includes a battery, a monitoring unit configured to generate availability information of the battery, and a charging and discharging controller configured to control charging and discharging of the battery. A first monitoring unit of a first power supply device acquires a state of a second battery of a second power supply device from a second monitoring unit of the second power supply device. When a failure occurs in the second monitoring unit, the first monitoring unit estimates a present state of the second battery, and generates estimation availability information of the second battery based on an estimation result. A second charging and discharging controller of the second power supply device acquires the estimation availability information, and controls charging and discharging of the second battery.
