| 1 | A Nonlinear Observer Approach of SOC Estimation Based on Hysteresis Model for Lithium-ion Battery显示文摘In this paper, a state of charge(SOC) estimation approach for lithium-ion battery based on equivalent circuit model and the input-to-state stability(ISS) theory has been proposed. According to the electrochemical performance of lithiumion battery, the equivalent circuit model with two RC networks is established, which includes hysteresis characteristic in inner electrochemical response process. The nonlinear relation between open circuit voltage(OCV) and SOC is obtained from a rapid test. Exponential fitting method is used to identify the parameters of the model. A novel state observer based on ISS theory is designed for lithium-ion battery SOC estimation. The designed observer is tested on AMESim and Simulink co-simulation. The simulation results show that the proposed method has a high SOC estimation accuracy with an error of about 2 percent. | Yan Ma Bingsi Li Guangyuan Li Jixing Zhang Hong Chen | 2017 | IEEE/CAA Journal of Automatica Sinica2017，4，2： | 7 |
| 2 | Fractional Modeling and SOC Estimation of Lithium-ion Battery显示文摘This paper proposes a state of charge(SOC) estimator of Lithium-ion battery based on a fractional order impedance spectra model. Firstly, a battery fractional order impedance model is derived on the grounds of the characteristics of Warburg element and constant phase element(CPE) over a wide range of frequency domain. Secondly, a frequency fitting method and parameter identification algorithm based on output error are presented to identify parameters of the fractional order model of Lithium-ion battery. Finally, the fractional order Kalman filter approach is introduced to estimate the SOC of the lithium-ion battery based on the fractional order model. The simulation results show that the fractional-order model can ensure an acceptable accuracy of the SOC estimation, and the error of estimation reaches maximally up to 0.5 % SOC. | Yan Ma Xiuwen Zhou Bingsi Li Hong Chen | 2016 | IEEE/CAA Journal of Automatica Sinica2016，3，3： | 2 |

| 5 | A review of the theory of Library Science in China: 1956-2016显示文摘Contemporary Library Science in China has gone through 60 years’ tough development since 1956. This paper tries to disclose the journey and achievements of Chinese Library Science in the past 60 years based on the analysis of published journal articles. This paper analyzes contemporary Chinese Library Science in the context of Chinese Library Science history and the international Library Science environment. Examining the historical progress of the Library Science in China, this paper divides the history into 5 phases: late start, wandering phase, tough starting phase, rebuilding phase, breaking phase and shining phase. | FAN Bingsi | 2017 | Journal of Library Science in China2017，，1： | 0 |
| 6 | Reading promotion and library science:Analysis on basic theory显示文摘Reading promotion has become one of the main library services.Basic theory in the field of reading promotion should include the definition of the reading promotion,its relation with library services and core values of librarianship.The target patron of reading promotion is all citizens,but focusing on people with special needs.Its theoretical characteristics include service orientation,patron,features and values of reading promotion.Aims of reading promotion in accordance with the core values of library are to help the non-reader group to love reading,to make people who lack reading ability to learn how to read,to make people with reading difficulty to overcome the barrier. | Bingsi FAN | 2014 | Journal of Library Science in China2014，，1： | 0 |
| 7 | Preparation of activated carbon with high surface area for high-capacity methane storage显示文摘Activated carbon(AC) was fabricated from corncob, which is cheap and abundant. Experimental parameters such as particle size of corncob,KOH/char weight ratio, and activation temperature and time were optimized to generate AC, which shows high methane sorption capacity. AC has high specific surface area(3227 m2/g), with pore volume and pore size distribution equal to 1.829 cm3/g and ca. 1.7-2.2 nm, respectively.Under the condition of 2℃ and less than 7.8 MPa, methane sorption in the presence of water(Rw = 1.4) was as high as 43.7 wt% methane per unit mass of dry AC. The result is significantly higher than those of coconut-derived AC(32 wt%) and ordered mesoporous carbon(41.2 wt%,Rw= 4.07) under the same condition. The physical properties and amorphous chaotic structure of AC were characterized by N2 adsorption isotherms, XRD, SEM and HRTEM. Hence, the corncob-derived AC can be considered as a competitive methane-storage material for vehicles,which are run by natural gas. | Bingsi Liu Wenshuo Wang Na Wang (Peter) Chak Tong Au | 2014 | Journal of Energy Chemistry2014，23，5： | 0 |
