  Abstract In this paper, application of a Battery Management System (BMS) with Battery Energy Storage System (BESS) is realized by using solar power. Proposed system is designed for four different 12V, 60Ah batteries used by general purpose as an uninterruptable power supply unit for electronics devices. Furthermore, in developed application, with respect to state of charge of each battery, either batteries are used as energy supply or batteries are charged by solar power. In addition to BMS, battery charger system in order to regulate battery charge voltage is applied. With the application in this paper, by controlling each batteries charge level, an efficient way to use of batteries are provided in order to have a long life Read More about this Article:  https://crimsonpublishers.com/eme/fulltext/EME.000574.php Read More  Crimson Publishers Google Scholar  Articles:  https://scholar.google.com/citations?view_op=view_citation&hl=en&user=2eS4vdYAA...

 

  Thermal Analysis of a Workpiece Material in an Electric Discharge Process by Debabrata Datta* in Evolutions in Mechanical Engineering_ Crimson Publishers Open Access Journals Abstract Go to EDM is a non-conventional thermo electric process wherein material erodes from the workpiece by a series of discrete sparks between the tool and workpiece immersed in a dielectric medium. This discharge occurs in a voltage gap between the electrode and workpiece. Thermal analysis is essential to quantify the material removal rate and also to know the performance of the material with respect to the defined process. A substantial research has been carried out to qualify the material under process. However, due to complex processes involved an Advanced Analysis is mandatory. Present study explains how one can understand the behavior of a workpiece for participating in EDM process. Thermal analysis model accurately predicts the temperature profile, material removal rate and quality of the pro...
