The design and simulation of a battery charger is presented, for medical applications using three-state mode charge, containing Buck converter lead-acid battery. Implementing Proportional Integral (PI) controllers, to modify the duty cycle converter, in such way that subjected 3 states during charging process, PI controller reference changes each states. In this with single controller. order pr...

Stand alone renewable energy based on photovoltaic systems accompanied with battery storage system are beginning to play an important role over the world to supply power to remote areas. The objective of the study reported in this paper is to elaborate and design a bond graphs model for sizing standalone domestic solar photovoltaic electricity systems and simulating the performance of the syste...

Abstract Because the electricity storage of renewable energy is irregular, battery in this system will be impacted by current. This also have a negative impact on life, increase project cost and lead to pollute environment. study proposes method improve life: hybrid super-capacitor lead-acid key solve these problems.

Uninterruptible power supplies (UPS), represented by lead-acid batteries, play an important role in various kinds of industries. They protect industrial technologies from being damaged by dangerous interruptions of an electric power supply. Advanced UPS monitoring performed by a complex battery management system (BMS) prevents the UPS from sustaining more serious damage due to its timely and ac...

Proper electric and thermal management of an HEV battery pack, consisting of many modules of cells, is imperative. During operation, voltage and temperature differences in the modules/cells can lead to electrical imbalances from module to module and decrease pack performance by as much as 25%. An active battery management system (BMS) is a must to monitor, control, and balance the pack. The Uni...

Battery storage (BS) systems are static energy conversion units that convert the chemical energy directly into electrical energy. They exist in our cars, laptops, electronic appliances, micro electricity generation systems and in many other mobile to stationary power supply systems. The economic advantages, partial sustainability and the portability of these units pose promising substitutes for...
