Abstract
The present invention provides a power storage device including a rack BMS that outputs measurement data and a failure flag of a battery rack including a plurality of battery cells, a communication conversion device that receives the measurement data and the failure flag from the rack BMS, subjects the measurement data to communication conversion, and outputs the measurement data, and a server that receives the measurement data from the communication conversion device, in which the communication conversion device stores the measurement data according to activation of the failure flag, and a method of operating the same.
Claims12
An energy storage system comprising:
- a rack battery management system (BMS) that outputs measurement data and a failure flag of a battery rack including a plurality of battery cells;
- a communication conversion device that receives the measurement data and the failure flag from the rack BMS, subjects the measurement data to communication conversion, and outputs the measurement data;
- and
- a server that receives the measurement data from the communication conversion device, wherein
- the communication conversion device stores the measurement data according to activation of the failure flag.
A method of operating an energy storage system, the method comprising:
- a process of receiving measurement data and a failure flag of a battery rack;
- a process of determining whether the failure flag is activated;
- a process of storing the measurement data in a memory when the failure flag is activated;
- a process of storing the measurement data in the memory by incrementing an index value whenever the failure flag is activated;
- and
- a process of overwriting the measurement data into the memory by resetting the index value when a failure flag exceeding a predetermined index is activated.
