Abstract

An apparatus for reporting fault information of a battery of a power storage system includes a receiving portion configured to receive state information of the battery from a battery management system of the power storage system, a controller configured to produce fault information of the battery from the state information of the battery received by the receiving portion by comparing the state information of the battery with a prestored reference value; and a display configured to display the fault information produced by the controller, wherein the receiving portion and the controller are positioned inside a storage space with the power storage system, and the display is outside of the storage space.

Claims

1. An apparatus for reporting fault information of a battery of a power storage system, the apparatus comprising:

a receiving portion configured to receive state information of the battery from a battery management system of the power storage system;

a controller configured to produce fault information of the battery from the state information of the battery received by the receiving portion by comparing the state information of the battery with a prestored reference value; and

a display configured to display the fault information produced by the controller, wherein the receiving portion and the controller are positioned inside a storage space with the power storage system, and the display is outside of the storage space.

2. The apparatus as claimed in claim 1, wherein the storage space is a container.

3. The apparatus as claimed in claim 1, wherein the controller transmits the fault information to an integrated power management system.

4. The apparatus as claimed in claim 1, wherein:

the fault information of the battery produced by the controller is classified into a plurality of fault codes, and

the controller determines whether an error condition exists with respect to each of the fault codes by comparing the state information of the battery according to the plurality of fault codes with a prestored reference value for each fault code.

5. The apparatus as claimed in claim 4, wherein the display includes a first LED that displays the fault information with respect to each fault code for which an error condition exists, and a second LED that displays lighting intervals of the first LED.

6. The apparatus as claimed in claim 1, wherein the battery includes a plurality of battery packs that are separately charged and discharged.

7. The apparatus as claimed in claim 6, wherein:

the plurality of battery packs are grouped in trays, each tray including a predetermined number of the battery packs, and

the trays are grouped in one or more racks.

8. The apparatus as claimed in claim 7, wherein:

each of the battery packs and/or each of the trays and/or each of the racks includes a battery management module, and

each battery management module intercommunicates with the battery management system of the power storage system.

9. An energy storage system, comprising;

a power generation system configured to generate electrical power;

a battery connected to a battery management system, the battery being configured to selectively store power from the power generation system or from a power grid and provide power to a load or to a power grid;

a power converter connected to the power generation system and a first node, the power converter being configured to convert the power generated from the power generation system to a voltage of the first node;

a bidirectional converter connected to the battery management system and the first node, the bidirectional converter being configured to provide a DC-DC conversion of power from the power grid and power from the power generation system to transfer to the battery, and to provide a DC-DC conversion of power from the battery to transfer to the load or the power grid;

an inverter connected to the first node and a second node, the inverter being configured to provide a DC-AC inversion of a voltage input through the first node to transfer to the load or to the power grid and to provide a AC-DC inversion of the power from the power grid to output to the first node;

a grid connector connecting the power grid and the inverter;

an integrated controller configured to block a connection between the power grid and the power storage system in an abnormal condition by controlling the grid connector, and controlling the power converter, the bidirectional converter, the inverter, the grid connector and the battery; and

an apparatus for reporting fault information of the battery, the apparatus including a receiving portion configured to receive state information of the battery from the battery management system;

a controller configured to produce fault information of the battery from the state information of the battery received by the receiving portion by comparing the state information of the battery with a prestored reference value; and

a display that displays the fault information produced by the controller.

10. The energy storage system as claimed in claim 9, wherein the controller transmits the fault information to an integrated power management system.

11. The energy storage system as claimed in claim 9, wherein the fault information of the battery produced by the controller is classified into a plurality of fault codes, and the controller determines whether an error condition exists with respect to each fault code by comparing the state information of the battery according to the plurality of fault codes with a prestored reference value for each fault code.

12. The energy storage system as claimed in claim 9, wherein the battery includes a plurality of battery packs that are separately charged and discharged.

13. The energy storage system as claimed in claim 12, wherein:

the plurality of battery packs grouped in trays, each tray including a predetermined number of battery packs, and

the trays are grouped in one or more racks.

14. The energy storage system as claimed in claim 9, wherein, the receiving portion and the controller are positioned inside an enclosed storage space with the power storage system, and the display is outside of the enclosed storage space.
