Abstract “
A chip for inductive battery charging is presented, which needs no external components except an antenna to capture the energy from an electromagnetic field. The integrated system blocks are a front-end to limit and rectify the induced alternating voltage and a charge regulator with three control loops for the current, the vol ....etc

Abstract:
This paper explores the recovery and rate capacity effect for batteries used in embedded systems. It describes the prominent battery models with their advantages and drawbacks. It then throws new light on the battery recov ery behavior, which can help determine optimum discharge profiles and hence result in significant improvement in battery lifetime. Finally it proposes a fast and accurate stochastic model which draws the positives from the earlier models and minimizes the drawbacks. The parameters for this model ....etc

Introduction:
Now the technology is far beyond a leap but still The most limiting factor for all our current and future developments is The availability of power. Starting with simple mobile systems followed by complex networked environments with flexible nodes there is always the need for energy that comes not from the power socket. And since the applications get more complex, should last longer and work more robust the demand for mobile energy increases day by day. The most common solution to have mobile power is of course ....etc

microcontroller based power monitoring for 600KVA BATTERY BACK UP
1.INTRODUCTION
The microcontroller-based power monitoring system is an electronic device used to continuously monitor the parameters of power such as voltage, current, frequency, etc at the various points of an electric or electronics devices. The entire system is controlled by the microcontroller (80C31) and it is the real time monitoring of various parameters. Thus the name REAL TIME MONITORING OF HIGH CAPACITY (400KVA-600KVA) BATTERY BACK UP SYSTEM. This system is an 8-chan ....etc

paper battery
A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nanotube s with a conventional sheet of cellulose-based paper. A paper battery acts as both a high-energy battery and supercapacitor , combining two components that are separate in traditional electronics . This combination allows the battery to provide both long-term, steady power production and bursts of energy. Non-toxic, flexible paper batteries have the potential to power the next generation of elect ....etc

Abstract

Since battery life directly impacts the extent and duration of mobility, one of the key considerations in the design of a mobile embedded system should be to maximize the energy delivered by the battery, and hence the battery lifetime. To facilitate exploration of alternative implementations for a mobile embedded system, in this paper we address the issue of developing a fast and accurate battery model, and providing a framework for battery life estimation of Hardware/Software (HW/SW) embedded systems. We introduce a stochastic mo ....etc

BATTERY CHARGERS & BATTERY BANKS
INTRODUCTION
NEED OF BATTERY CHARGERS & BATTERY BANKS
Station battery charger is used to supply the control power to the electrical switchgear like breakers etc which need the DC supply for it’s operation and in case of failure of electrical power the control power is continued to be fed by the battery.
Battery Charger consists of
1) Float Charger
2) Boost Charger
Schemes for Battery Chargers
1) FC & FCBC scheme
2) FCBC & FCBC scheme
SINGLE LINE ....etc
