... recurrent unit (GRU) NN and an adaptive unscented Kalman filter (AUKF) method is proposed. A GRU NN is first used to acquire the nonlinear relationship between the battery SOC and battery measurement signals, and then an AUKF is utilized to filter out the output noise of the NN to further improve estimation...

Real-Time State of Charge Estimation of the Extended Kalman Filter and Unscented Kalman Filter Algorithms Under Different Working Conditions

Xiongbin Peng, Yuwu Li, Wei Yang, Akhil Garg
Journal: Journal of Electrochemical Energy Conversion and Storage
Publisher: ASME
Article Type: Research Papers
J. Electrochem. En. Conv. Stor. November 2021, 18(4): 041007.
Paper No: JEECS-20-1159
https://doi.org/10.1115/1.4051254
Published Online: June 4, 2021
... Kalman filter (EKF) algorithm and the unscented Kalman filter (UKF) algorithm were applied to estimate the SOC of the battery based on the proposed model. The SOC experimental results obtained under dynamic stress test (DST), federal urban driving schedule (FUDS), and US06 cycle conditions were analyzed...
