State of Charge Estimation for Li-Ion Batteries Based on an Unscented H-Infi nity Filter
Yuanyuan Liu,Tiantian Cai,Jingbiao Liu,Mingyu Gao,Zhiwei He 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.6
The state of charge (SOC) of lithium-ion batteries refl ects their remaining capacity. Accurate estimation of SOC helps battery safety and is benefi cial to the effi cient management of batteries. The charging and discharging processes of lithium-Ion batteries are very complicated, and it is diffi cult to obtain accurate SOC estimation results. Therefore, it is important to study improved algorithms for SOC estimation for this nonlinear non-Gaussian battery system. In this paper, we propose an unscented H-infi nity fi lter (UHF) based SOC estimation method, which combines the advantages of both the unscented Kalman fi lter (UKF) and the H-infi nity fi lter (HF). The UKF propagates the sigma points through the nonlinear system and does not need the fi rst-order linear approximation of the system equation, while the HF can suppress the non-Gaussian noise in the system to the greatest extent. The proposed UHF based SOC estimation algorithm is verifi ed and evaluated in the battery management system, and further optimized in practical problems. Experimental results show that the proposed UHF based algorithm can perform accurate SOC estimation for lithium-ion batteries, and is superior to the UKF based SOC estimation.

A series of 5-substituted 1-H-tetrazoles weredesigned and synthesized as potent anticonvulsant agents. Their preliminary anticonvulsant activities were evaluatedusing maximal electroshock and subcutaneouspentylenetetrazole (scPTZ) seizure tests. Neurotoxicity wasdetermined using rotarod test. The results indicated that thecompound 2j in scPTZ model exhibited the ED50 values of83.3 mg/kg, superior to the standard drug ethosuximidewith the maximum activity. In addition, compound 2kshowed the most potent activity in MES model with ED50value of 9.6 mg/kg and TD50 value of 189.5 mg/kg afterintraperitoneal injection in mice, and displayed a highprotective index (TD50/ED50) of 19.7 compared to referenceantiepileptic drugs.
