Abstract
A battery analysis apparatus includes a site information generating unit for generating information of an energy storage system (ESS) site, a data collecting unit for collecting state data of at least one battery included in the ESS site, and an analyzing unit for analyzing a state of the battery based on the state data of the battery.
Claims15
A battery system comprising:
- a battery management system;
- and
- a battery analysis apparatus comprising:
- a site information generator configured to update information on a new energy storage system (ESS) site in addition to information on existing ESS sites through a batch file each time the new ESS site is added;
- a data collector configured to collect new battery state data of the new ESS site and latest battery state data of the existing ESS sites through the batch file;
- a data processor configured to generate pre-processing data by performing pre-processing on the new battery state data of the new ESS site and the latest battery state data of the existing ESS sites;
- and
- an analyzer configured to:
- analyze states of batteries included in the new ESS site and the existing ESS sites based on the pre-processing data in an order set out by the batch file,
- calculate charging and discharging behaviors of the batteries based on the states of the batteries, and
- extract an abnormal battery having the charging and discharging behaviors falling out of a reference range and classify an abnormality type of the abnormal battery,
- wherein the battery analysis apparatus is configured to transmit abnormality information including information on the abnormal battery and information on the abnormality type to the battery management system, and
- wherein the battery management system controls an on and off of a switch connected to the abnormal battery based on the transmitted abnormality information including the information on the abnormal battery and the information on the abnormality type.
