Provided an area-specific environment management system, which manages an environment in an individual one of a plurality of areas, the system including: a biological information sensor that acquires biological information about at least one of an individual and a group who belongs to an individual one of the areas; an environmental information sensor that acquires environmental information about an individual one of the areas; an arousal level estimation section that estimates an arousal level with respect to the biological information by using an arousal level estimation model; and an environment provision section that provides an environment to an individual one of the areas based on the arousal level and the environmental information, wherein the arousal level includes, as a state to which the arousal level belongs, a state from sleepy until awakened; a wakeful state; and an excessively wakeful state, and wherein the environment provision section includes an individual control mode corresponding to a state to which the arousal level belongs and manages an environment to be provided to an individual one of the areas based on the control mode.

Area-specific environment management system for providing environment in which arousal level is adjusted, method, and recording medium therefor

A control device of the present invention includes: an OCV estimating unit that estimates, based on a voltage value and a current value of a controlled device, an OCV of the controlled device; a capacity calculating unit that calculates an integrated capacity of the controlled device based on the current value of the controlled device; and a control unit that controls discharging and charging of the controlled device, and calculates a full capacity of the controlled device based on: a first SOC and a second SOC at a predetermined first OCV and a predetermined second OCV during the discharging or the charging of the controlled device; a first integrated capacity and a second integrated capacity at the first OCV and the second OCV during the discharging; and a third integrated capacity and a fourth integrated capacity at the second OCV and the first OCV during the charging.

Control device, control method, and recording medium

A storage battery control device includes: a voltage measurement means for measuring terminal voltage of a storage battery; a current measurement means for measuring charge current and discharge current of the storage battery; a capacity calculation means for calculating a cumulative capacity of the storage battery by using the charge current measured by a current measurement unit; a control means for determining an operation of the storage battery, based on at least one of the terminal voltage, the charge current, the discharge current, and the cumulative capacity; and a charging/discharging control means for causing the storage battery to operate in accordance with an instruction from the control means, and the charging/discharging control means causes the storage battery to charge by a first charging method from a discharge end voltage to a first charge voltage, to charge by a second charging method at the first charge voltage, to charge by the first charging method from the first charge voltage to a second charge voltage, and to charge by the second charging method at the second charge voltage.
