QT-BGCS-2118
QT-BGCS act as the master of the battery management system, it connects the battery pack and other ECUs. The BGCS should collecting battery information from the reports by the slaves.
BGCS is responsible for the current sampling, insulation detection and also communication with OBC, MCU and ect.
