Development of charge level monitoring of lead-acid battery bank for PV system using fuzzy logic in LabView

This paper presents a charge level monitoring system for lead acid battery bank in Solar Panel setup. The research implements the approximate linear relationship between the charge level and the current-voltage for lead acid batteries. Prediction method utilizes is the objective fuzzy logic approach. Both the interphase of the instrument and the fuzzy system together with the fuzzy rule system were created using LabView. Dataset used is based on an actual 12-hour data gathering of charging cycle and current-voltage readings. Simulation results show that the developed system generated correctly the charge level of the battery using only the instantaneous voltage and current readings from the sensors

Conducting Polymer Nanomaterials and Their Applications

A paradigm shift takes place in the fabrication of conducting polymers from bulky features with microsize to ultrafine features with nanometer range. Novel conducting polymer nanomaterials require the potential to control synthetic approaches of conducting polymer on molecular and atomic levels. In this article, the synthetic methodology of conducting polymer has been briefly considered with chemical oxidation polymerization and electrochemical polymerization. The recent achievements in the fabrication of conducting polymer nanomaterials have been extensively reviewed with respect to soft template method, hard template method and template-free method. It also details the morphological spectrum of conducting polymer nanomaterials such as nanoparticle, core-shell nanomaterial, hollow nanosphere, nanofiber/nanorod, nanotube, thin film and nanopattern and nanocomposite. In addition, their applications are discussed under nanometer-sized dimension.This work has been financially supported by the Brain Korea 21 program of the Korean Ministry of Education and the Hyperstructured Organic Materials Research Center supported by Korea Science and Engineering Foundation
