Solar Powered Portable Charger for Disaster Recovery

4929 руб.
This book presents the development of solar powered portable charger to charge mobile phone during disaster recovery. It emphasizes on efficient solar energy harvesting circuit for charging mobile phone battery with the utilization of intermediate battery. In this book, Sealed Lead-Acid (SLA) battery was chosen as intermediate battery to protect the Lithium Ion battery which seems very sensitive to overcharging and discharging. Concerning on delivering the most efficient portable charger, polycrystalline silicon solar panel was selected which may supply up to 400mW of average power. In addition, Pulse Width Modulation (PWM) charging method was employed using Arduino microcontroller. During disaster, main power supply will be interrupted. If only the victims can communicate through their mobile phone, there will be high chance that they can be rescued by the rescue team. Note that, the portable cell tower can be set up by the relevant authorities during disaster. This book can benefit government, NGO, or volunteers during disaster, as well as many people in disaster prone area.

Gel polymer electrolytes and effects of swift heavy ion irradiation

5490 руб.
The global energy crisis and environmental pollution have experienced an enormous push for development of alternative energy sources with an efficient energy storage system. Among the different energy storage systems, lithium ion battery is the most attractive one due to high energy density and long cycle life. One of the key components of these lithium or lithium ion batteries is the ion conducting polymer electrolyte. This book provides the scientific approaches to synthesize and characterize different gel and composite gel polymer electrolyte systems for possible application in lithium ion batteries. An attempt has been made in this book to investigate the basic ion conduction mechanism involved in the formation of polymer electrolytes and develop new polymer gel electrolyte systems which have high ionic conductivity and electrochemically stable. Another approach described in the book is the ion beam modification of materials. The effect of swift heavy ions irradiation on ionic conductivity of gel polymer electrolytes is also discussed in this context. This book will be beneficial for the students and researchers working on polymer electrolyte materials for lithium ion battery.

This book presents the development of mechanical powered portable charger to charge mobile phone during disaster recovery. It emphasizes on efficient mechanical energy harvesting circuit for charging mobile phone battery with the utilization of intermediate battery. In this book, Sealed Lead-Acid (SLA) or dry battery was selected as an intermediate battery to protect the Lithium Ion battery which is very sensitive to overcharging and discharging. Three modules are employed in this book, including a DC/DC boost converter circuit, SLA charging circuit and mobile phone charging circuit utilizing Arduino microcontroller. During disaster, main power supply will be interrupted. If only the victims can communicate through their mobile phone, there will be high chance that they can be rescued by the rescue team.

Battery-aware Multiprocessor Task Scheduling

4839 руб.
Battery life determines the duration and the extent of mobility for the battery-powered portable embedded systems and is a key performance metric for scheduling tasks on these multiprocessor systems. The main challenge is to space out the tasks to be executed on the multiprocessor system with the objective of shaping the battery discharge profile so as to enhance battery life, while at the same time, meeting the real-time timing constraints of the tasks. The current monograph addresses battery-aware static scheduling of precedence constrained task graphs with non-negligible intertask communication onto fully connected multiple processors in battery-powered mobile embedded systems. We propose a scheduling scheme comprising of genetic algorithm and simulated annealing techniques, both of which can efficiently explore the search space of all possible legal schedules to find a battery-efficient one. We demonstrate the effectiveness of our scheduling scheme over existing approaches on example task graphs and study the impact on battery life using a battery model. Our experimental results shows considerable improvement in battery life over existing approaches.

Smart Instrument for Battery Monitoring

8890 руб.
The portable devices for battery health and charge monitoring are always a challenge for engineers. This work is coin for development of micro-controller based smart instruments to indicate status of battery. It aims to develop an artificial intelligence based battery monitoring instrument which indicates the charge status of the battery. The instrument uses a Neuro-Fuzzy approach coupled with on line sensing of parameters to map the battery behaviour. The battery behaviour shows non-linear characteristics due to complex physical and chemical process and is hard to predict. This behaviour is understood by modelling the physical parameters. The soft computing techniques (artificial neural network and fuzzy logic) have been used to model the battery behaviour using easily measurable five parameters viz. voltage, current, internal resistance, temperature and consumption time. The developed instrument predicts battery status on line and indicates the battery status in terms of state of charge that results in timely detection of faulty state of the battery which is very essential for reliability and safety of all instruments.
