“…Good modeling method not only considers the electrical characteristic of battery, but also needs to be combined with the working status of battery and charging-discharging strategy [35][36][37]. Because the proposed method requires correction parameters in the operation process, selection of high precision battery model for this method is very important.…”

This paper discusses a design of a Battery Management System (BMS) solution for extending the life of Nickel-Metal Hydride (NI-MH) battery. Combined with application of electric boat, a State of Charge (SoC) optimal operation range control method based on high precision energy metering and online SoC correction is proposed. Firstly, a power metering scheme is introduced to reduce the original energy measurement error. Secondly, by establishing a model based parameter identification method and combining with Extended Kalman Filter (EKF) method, the estimation accuracy of SoC is guaranteed. Finally, SoC optimal operation range control method is presented to make battery running in the optimal range. After two years of operation, the battery managed by proposed method has much better status, compared to batteries that use AH integral method and fixed SoC operating range. Considering the SoC estimation of NI-MH battery is more difficult becausing special electrical characteristics, proposed method also would have a very good reference value for other types of battery management.

“…To reduce the experimental time, an extrapolation of the results has been made by considering the final voltage a fixed value in all the experiments except the LED LCD case. To characterize the discharge curve of the battery, the state of charge (SOC) is extracted from the linear mapping of the relation between the open-circuit voltage (VOC) and SOC (1) proposed by H. Rahimi-Eichi et al [20].…”

There has been much interest in replacing traditional information supports with more technological solutions in recent years. New technologies which allow paper-like perception with minimal power needs have emerged as low-power wireless scenarios. A priority for these new supports is to create the architecture for a scalable solution which maintains minimal power requirements. The retail industry demands a new information infrastructure that improves customer and employee satisfaction. In this work, authors propose an information provision architecture based on E-Paper and carry out an experiment where different smart labeling architectures based on Paper, E-Paper, LED liquid crystal display (LCD) and Dot-matrix LCD were tested in order to determine which is best suited for a real labeling environment. Enclosed in a research project called SMARKET, the authors pilot-tested the work in a real supermarket, having the opportunity to survey employees and customers about satisfaction and frustration with the use of the architectures proposed in this research work.

Abstract. The open circuit voltage (OCV) of lithium ion battery is a key parameter for hybrid electric vehicle (HEV) to estimate the state-of-charge (SoC). And its instability will lead to big error of SoC estimation and have difficulty in implementing the dynamic control strategy of HEV, especially when the lithium ion battery rests after regenerative braking. According to the theory of electrochemistry, the lithium iron phosphate battery is studied in order to analyze the influence mechanism of lithium ion diffusion on the OCV when it rests after charge. And an OCV model appropriate for the rest period after charge is built by combining experiment with parameter identification method. The result of experiment shows that the OCV model is consistent with the OCV characteristic.
