More Information
Summary:Provided is a battery device which comprises: a plurality of battery packs; and a first processor connected to the plurality of battery packs through a first communication bus and managing the plurality of battery packs. A second processor is connected to the plurality of battery packs through a second communication bus. A third processor of each battery pack calculates a deviation between cell data sensed by each battery cell and a representative value of the cell data sensed in the plurality of battery cells, and sends a message including the deviation to the second processor through the second communication bus. Therefore, a load on the communication bus can be reduced. 배터리 장치는 복수의 배터리 팩 및 복수의 배터리 팩과 제1 통신 버스를 통해 연결되어 있으며 복수의 배터리 팩을 관리하는 제1 프로세서를 포함하며, 제2 프로세서는 복수의 배터리 팩과 제2 통신 버스를 통해 연결되어 있다. 각 배터리 팩의 제3 프로세서는 각 배터리 셀에서 감지한 셀 데이터와 복수의 배터리 셀에 감지한 셀 데이터의 대푯값 사이의 편차를 계산하고, 편차를 포함하는 메시지를 제2 통신 버스를 통해 제2 프로세서로 전달한다.
