This paper presents a Coulomb counting algorithm using the estimating OCV through short rest time, such as traffic signal time. Proposed could enhance SOC accuracy frequent reset greatly even though error occurs. Also is implemented for highly accurate estimation by prediction, an improvement of required time and compensation error. The proposed verified experiment UDDS profile it that improve up to 2.07%.
Wireless charging of electric vehicles based on wireless power transfer (WPT) has become increasingly popular in recent years. However, a leakage electromagnetic field (EMF) that affects other electronic devices or the human body is inevitably generated from coils WPT system, and requirements regarding suppression EMF are increasing. In this paper, we propose novel three-phase line system for reduction EMF. The proposed structure employs six lines to reduce magnetic flux. This compared with...
In this paper, the State of Charge (SOC) estimation algorithm is proposed using Direct Current Internal Resistance (DCIR) repetitive calculation, which reflects renewed Open Circuit Voltage (OCV) in real-time by measured DCIR through constant current injection method. Therefore, it possible to improve error because there no integration and reset interval. Finally, performance method evaluated comparing with estimated SOC result Coulomb-Counting under various C-rates experimental conditions....
TiO2 nanobarbed fiber (NBF) structures consisting of nanorods (NRs) on nanofibers (NFs) were fabricated. The mean length and diameter the NRs grown for 6 h was 1.38 microm 71 nm, respectively. One NR connected to other junction points between increased with increasing length. crystal structure NFs rutile anatase, After post-annealing, only intensity NBF peaks without any significant structural changes. Raman spectroscopy showed that consisted anatase (TiO2 NFs) NRs). bandgap prepared during...
【Cu(In,Ga) $Se_2$ (CIGS) thin films were annealed on molybdenium/sodalime glass substrates of $300{\times}300mm^2$ by rapid thermal processing (RTP) with 2-step rising-temperature times in $N_2$ ambient. Morphological property, structural characteristics and chemical composition the precursor CIGS influenced directly a change $1^{st}$ -step time RTP whereas there is no significant difference different $2^{nd}$ (final crystallization temperature). The shorter obtained higher photovoltaic cell...
