Energy storage system and temperature control method for the same

Abstract

Disclosed is an energy storage system and a temperature control method for the same. The energy storage system includes a first battery group having a plurality of sections, which respectively have at least one battery module and at least one cooling fan; at least one first slave battery management system (BMS) coupled to the first battery group to monitor a temperature value of battery modules included in the first battery group for each section and generate first temperature information having the monitored temperature value for each section; a master BMS configured to transmit the first temperature information according to a predetermined rule; and a control unit configured to output a first control signal for adjusting a rotation speed of at least one cooling fan provided in at least one of the plurality of sections, based on the first temperature information transmitted from the master BMS.

Dependencies are inferred from the claim text.
