A power management system is configured to comprise: a plurality of power management units (32, 36, 38, 40, 42) that divide power information about a whole facilities complex into power information about a plurality of management areas, and each of which takes partial charge and manages power information about the area pertaining thereto; and a system controller (30) that is connected to each of the power management units (32, 36, 38, 40, and 42) through a communication element, and that is for conducting power management of the whole facilities complex. When failure information is detected from the power information, an alarm signal is output by the system controller (30), and details about the failure information, which are located at a power management unit (32) for a power apparatus, are transmitted to the other power management units via a server (200).

Provided is a power management system capable of controlling charge and discharge of storage batteries according to power requirement of load even when handling electric power of large scale. A system controller receives load-related information data including the power requirement of load and storage battery-related information data including a state of a storage battery assembly including multiple storage batteries and creates an overall charge-discharge control instruction for the entire power management system based on the load-related information data and the storage battery-related information data. A hierarchical charge-discharge control apparatus receives the overall charge-discharge control instruction from the system controller and performs charge-discharge control of the multiple storage batteries, classified into hierarchical levels, on a hierarchical level basis.

摘要:
An acquisition unit acquires state of health of a storage battery provided to supply electric power, in which the state of health shows a smaller value as the storage battery deteriorates. A display unit performs notification when state of health acquired by the acquisition unit is smaller than a first threshold value. When the acquisition unit has not acquired state of health for a predetermined period, the display unit performs notification if the elapsed period from the manufacture of the storage battery is longer than a second threshold value.

This storage unit includes a storage portion that stores power, a converter that converts power, a first temperature detection portion arranged in the vicinity of the converter, and a housing that houses at least the converter, the first temperature detection portion, and the storage portion.
摘要:
A power storage unit is provided which is able to facilitate recalibration and which is able to supply power even while recalibration is being performed. A method for correcting the capacity values of storage batteries, and a power storage system are also provided.In the power storage unit, a control unit turns ON a portion of the switches to connect a portion of the storage batteries to the charge and discharge path for correction, and corrects the capacity value of the portion of storage batteries by charging and discharging the portion while the other switches are turned OFF to disconnect the other storage batteries from the charge and discharge path.
摘要:
A server installed indoors determines whether or not an abnormality has occurred indoors. If the server determines that the abnormality has occurred, it causes an indoor display device having a display function to display a visually effective warning. A user is thereby promptly informed of the occurrence of the abnormality, and an appropriate countermeasure is swiftly taken. Upon detecting an indoor abnormality, the server decides on a display device for displaying the abnormality on the basis of a condition of a display device for displaying an abnormality and the circumstances of display devices connected to a network. Further, the server forms a screen used to report the abnormality depending on the contents thereof, and causes the display device, which has been decided on for the display of the abnormality, to display the screen.
