Abstract
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 monitoris smaller than the defined value, a discharge control switchis turned off. A voltage Vx corresponding to a voltage between terminals Tand Tis input to an A/D port of a controllerand 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 controllerturns off a switch circuitto turn off power to the battery monitor
