Claims18
A method for driving a battery pack comprising a first rack battery management system (BMS) configured to communicate data with a second rack BMS, the method comprising:
- outputting first data at the first rack BMS of the battery pack;
- determining whether a response to the first data has been received from another rack BMS within the battery pack;
- setting a driving mode of the first rack BMS based on whether the response has been received;
- and
- driving the first rack BMS based on the set driving mode,
- wherein the first and second BMSs comprises first and second communication interfaces,
- wherein the first communication interface of the first rack BMS is configured to output the first data to the second interface of the second rack BMS,
- and wherein the second communication interface of the second rack BMS is configured to transmit the response to the first communication interface of the first rack BMS.
A method of driving a battery pack comprising a plurality of rack battery management systems (BMSs) including first and second rack BMSs, the method comprising:
- transmitting first data from the first rack BMS to the second rack BMS within the battery pack;
- determining whether the first rack BMS has received a response to the first data from the second rack BMS;
- setting driving modes of the first and second rack BMSs based on whether the first rack BMS has received the response from the second rack BMS;
- and
- when the first rack BMS has received the response from the second rack BMS, driving the first rack BMS as a master BMS and the second rack BMS as a slave BMS,
- wherein the first and second BMSs comprises first and second communication interfaces,
- wherein the first communication interface of the first rack BMS is configured to output the first data to the second interface of the second rack BMS,
- and wherein the second communication interface of the second rack BMS is configured to transmit the response to the first communication interface of the first rack BMS.
A battery pack, comprising:
- a first rack battery management system (BMS) and a second rack BMS,
- wherein the first rack BMS configured to i) output first data, ii) determine whether a response to the first data has been received from the second rack BMS within the battery pack, iii) set a driving mode of the first rack BMS based on whether the response has been received, and iv) operate based on the set driving mode,
- wherein the first and second BMSs comprises first and second communication interfaces,
- wherein the first communication interface of the first rack BMS is configured to output the first data to the second interface of the second rack BMS,
- and wherein the second communication interface of the second rack BMS is configured to transmit the response to the first communication interface of the first rack BMS.
