  "textContent": "Discharge is stopped when a voltage of a battery becomes smaller than a defined value or a remaining capacity of the battery reaches 0, and further, when power to a system cannot be maintained, the system is automatically shut down to be put into a shutdown state. When it is determined that the voltage of the battery or an SOC from a battery monitor 11 is smaller than the defined value, a discharge control switch 22 is turned off. A voltage Vx corresponding to a voltage between terminals T1 and T2 is input to an A/D port of a controller 21 and a value thereof is monitored. When it is determined that the voltage Vx input to the A/D port is smaller than a defined value, the controller 21 turns off a switch circuit 12 to turn off power to the battery monitor 11. Together with this, a control switch 25 is turned off by a switch control signal S1. As a result, operation of a DC-DC converter 24 stops and it is shut down.",
