The effectiveness of a battery management system (BMS) in lithium-ion batteries (LIBs) is significantly dependent on the accuracy of battery sensors. However, owing to the highly nonlinear nature of LIBs, detecting small uncertainties in sensor measurements, which can lead to high estimation errors,...
