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;

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

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.

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; 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. 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 an entire CRC of the integrated management package;

a header reading operation of reading header information of one of the individual software;

an ID and version check operation of checking ID and version information of one of the individual software;

a data reading operation of reading data of one of the individual software;

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.

5. The method of claim 4, wherein the header information is configured including an ID, a version, and a length of the software.

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

an energy storage system (ESS) including one or more battery packs;

an ESS control unit including software for controlling a device mounted in the ESS; and

an ESS control server configured to generate a control command and remotely control the ESS control unit,

wherein the ESS comprises a DC-DC converter and a BMS;

the ESS control unit comprises respective software of the DC-DC converter and the BMS; and

the ESS control server comprises a control module for integrating, managing, and updating the respective software.

7. The system of claim 6, wherein the ESS control server generates and manages an integrated management package by integrating each header information of the DC-DC converter and the BMS in header information.

8. The system of claim 6, wherein the ESS control unit receives an update control command from the ESS control server to sequentially update software of the DC-DC converter and the BMS.

9. The system of claim 7, wherein the integrated management package performs an error detection by calculating an entire cyclic redundancy check (CRC) value.

10. The system of claims 7, wherein the header information is configured including an ID, a version, and a length of the software.
