Abstract

The invention provides a cooperative control system and a cooperative control method of IT devices and storage batteries. The characteristics (time, frequency, and spacing) of coming shutdown is judged in advance, the presumed shutdown can be controlled through the cooperation of the IT devices and an uninterrupted power device having the storage batteries, thereby realizing the high efficiency of the charging and discharging of the storage batteries. The cooperative control system includes a commercial power supply (10), a voltage recorder (20) for measuring the voltage of the commercial power supply, an uninterrupted power device (30) connecting with a plurality of storage batteries (32), a power supply connector (40) equipped with a power determining mechanism, and a plurality of IT devices (50) including servers (51) connecting with the power supply connector. Controlling parts (55) inside the servers predict the continuous time of the future shutdown, the power limit value of the IT devices is figured out based on the remain of the storage batteries and the predicted shutdown time, and the power of the IT devices is controlled to satisfy the power limit value.

Description

technical field

[0001] The present invention relates to a system including IT equipment and a large-capacity storage battery, and more particularly to a cooperative control system of IT equipment and storage battery suitable for efficiently using the storage battery and stably operating the IT equipment for a long time. Background technique

[0002] In areas where the basic equipment of the power grid is insufficient, power outages occur frequently. Therefore, a method is adopted in which a generator is installed in a building, and the generator is operated during a power outage to supply electric power in the building. In the server room, an array of lead storage batteries required for several hours of repair of the generator is further installed in case of failure of the generator, and power is supplied to the server and client PCs. Generally, the storage battery array employs a system in which the capacity of the lead storage battery of an uninterruptible power supply (U...
