Fault diagnosis for cell voltage inconsistency of a battery pack in
The blue solid line is the vehicle speed, the green dotted line is the vehicle state, and the red dotted line is the poor consistency alarm signal. The poor consistency alarm (signal is 1) occurs when the vehicle speed is not 0. As the vehicle state is 1 (vehicle start state), it indicates that it is a poor consistency fault in the driving state.
