Abstract

The present disclosure relates to a method of managing and updating two different versions of software, and more particularly, to an integrated management and update method of software including integrating software of a DC-DC converter and a battery management system (BMS) installed in residential Energy Storage System (ESS) to generate and manage one integrated management package, and sequentially executing a software update procedure of the DC-DC converter and the BMS in the integrated management package.

Claims

1. A method of integrating and managing software of a DC-DC converter and a battery management system (BMS), the method comprising:

an individual software header information confirmation operation of confirming header information of each control software of the DC-DC converter and the BMS, each control software having respective version information;

an individual software data storage operation of storing data related to the individual software;

an integrated management package generation operation of generating an integrated management package that integrates and manages individual software for controlling the DC-DC converter and the BMS, wherein the management package includes the respective version information from the control software of the DC-DC converter and the BMS; and

a control command transmission operation of transmitting a control command to a remote control unit that includes software for controlling each of the DC-DC converter and the BMS, whereby transmitting the control command causes the remote control unit to update software of each of the DC-DC converter and the BMS based on the integrated management package.

2. The method of claim 1, wherein the integrated management package generation operation comprises

an integrated management package header information generation operation of integrating individual header information of the DC-DC converter and the BMS into header information to generate integrated header information, wherein the integrated header information includes integrated version information generated from the respective version information of the control software of the DC-DC converter and the BMS;

and

a cyclic redundancy check (CRC) calculation operation of calculating an entire CRC value of the integrated management package.

3. The method of claim 2, wherein the header information is configured including an ID, a version, and a length of the software.

4. The method of claim 2, wherein the integrated version information is equal in size to the version information of the control software of the DC-DC converter and equal in size to the version information of the control software of the BMS.

5. The method of claim 4, wherein in the control command transmission operation, transmitting the control command is based on an indication from the integrated version information that an update is necessary.

6. The method of claim 1, wherein the remote control unit that includes software for controlling each of the DC-DC converter and the BMS is further configured to control operations of the DC-DC converter and the BMS.

7. The method of claim 1, wherein transmitting the control command causes the remote control unit to perform:

a first execution operation for updating software of one of the DC-DC converter or the BMS based on the integrated management package using an update tool;

a termination operation for terminating of the first execution operation; and

after the termination operation, a second execution operation for updating software of the other of the DC-DC converter or the BMS based on the integrated management package using the same update tool as the first execution operation.

8. A method of integrating and updating two or more individual software, the method comprising:

an integrated management package execution operation of reading an integrated management package file integrating the individual software;

a CRC check operation of checking a CRC of the entire integrated management package;

a header reading operation of reading header information of one of the individual software, the header information stored in the integrated management package file;

an ID and version check operation of checking ID and version information of one of the individual software, the ID and version information included in the header information stored in the integrated management package file;

a data reading operation of reading data of one of the individual software stored in the integrated management package file;

an execution and termination operation of executing and terminating an update of one of the individual software; and

sequentially performing the header reading, ID/version checking, data reading and updating for the remaining software of the individual software.

9. The method of claim 8, wherein the header information is configured including an ID, a version, and a length of the software.

10. The method of claim 8, wherein the individual software control operations of respective hardware in one-to-one correspondence.

11. The method of claim 10, wherein one individual software controls operation of a first hardware configured to perform DC voltage transformation from an input DC into AC, and wherein another individual software controls operation of a second hardware configured to monitor at least one of voltage, current, or temperature of a plurality of battery cells.

12. A system for integrating, managing, and updating software of a DC-DC converter and a battery management system (BMS), the system comprising:
