Lithium ion (Li-ion) batteries have been extensively used in consumer electronics because of their characteristics, such as high efficiency, long life, and gravimetric volumetric energy. In addition, Li-ion are becoming the most attractive candidate electrochemical storage systems for stationary applications, well power source sustainable automotive back-up supply applications. This paper gives an overview battery chemistries that available at present market, describes three out four main...
The development of lifetime estimation models for Lithium-ion battery cells, which are working under highly variable mission profiles characteristic wind power plant applications, requires a lot expenditures and time resources. Therefore, batteries have to be tested accelerated aging conditions. This paper presents three-stage methodology used testing batteries. results obtained at the end process were parameterization performance-degradation model, is able predict both capacity fade...
This paper introduces a versatile Y-source boost dc/dc converter intended for distributed power generation, where high gain is often demanded. The proposed uses impedance network realized with tightly coupled three-winding inductor voltage boosting that presently unmatched by existing networks. also has more variables tuning the required and, hence, degrees of freedom meeting design constraints. These capabilities have been demonstrated mathematical derivation and experimental testing. For...
Lithium-ion batteries have developed into a popular energy storage choice for wide range of applications because their superior characteristics in comparison to other technologies. Besides modelling the performance behavior batteries, it has become huge interest accurately diagnose state-of-health (SOH). At present, are diagnosed by performing capacity or resistance (current pulse) measurements; however, majority cases, these measurements time consuming and result changing state battery as...
Developers and manufacturers of battery management systems (BMSs) require extensive testing controller Hardware (HW) Software (SW), such as analog front-end performance generated control code. In comparison with the tests conducted on real batteries, a state-of-the-art hardware-in-the-loop (HIL) simulator can be more cost time effective, easier to reproduce, safer beyond normal range operation, especially at early stages in development process or during fault insertion. this paper, an HIL...
Abstract In designing and controlling fuel cell systems, it is advantageous to have models which predict behaviour in steady‐state as well dynamic operation. This work examines the use of electro‐chemical impedance spectroscopy (EIS) for characterising developing an model a high temperature PEM (HT‐PEM) stack. A Labview virtual instrument has been developed perform signal generation data acquisition needed EIS. The typical output EIS measurement on Nyquist plot, shows imaginary real parts...
The use of electric vehicles (EVs) is advantageous because zero emission, but their market penetration limited by one disadvantage, i.e., energy storage. Battery EVs (BEVs) have a range, and batteries take long time to charge, compared with the it takes refuel tank vehicle an internal combustion engine (ICE). Fuel cells (FCs) can be added EV as additional source. These are faster refill will therefore facilitate transition from running on fossil fuel electricity. Different setups FC...
Uninterruptible power supply (UPS) systems have incorporated in their structure an electrochemical battery which allows for smooth when a failure occurs. In general, UPS are based on lead acid batteries; mainly valve regulated (VRLA) battery. Recently, lithium ion batteries getting more and attention use the back-up UPSs, because of superior characteristics, include increased safety higher gravimetric volumetric energy densities. This fact them to be smaller size weight less than VRLA...
In this work the effects of reformate gas impurities on a H3PO4-doped polybenzimidazole (PBI) membrane-based high temperature proton exchange membrane fuel cell (HT-PEMFC) are studied. A unit assembly with BASF Celtec®-P2100 electrode (MEA) 45 cm2 active surface area is investigated by means impedance spectroscopy. The concentrations in anode feed all impurities, unconverted methanol-water vapor mixture, CO and CO2 were varied along current density according to multilevel factorial design...
