CHAPTER ONE 1.1 INTRODUCTION While most modern electrical appliances receive their power directly from the utility grid, a growing number of everyday devices require electrical power from batteries in order to achieve greater mobility and convenience. Rechargeable batteries store electricity from the grid for later use and can be conveniently recharged when their energy has been drained. Appliances that use rechargeable batteries include everything from low-power cell phones to high-power ...

ABSTRACT  This project presents the design and construction of a battery charger. A battery charger is an electrical/electronic device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The system consists of a step down transformer, an AC to DC converter and a DC voltage regulator. The circuits are designed using copper wire, rectifier diodes, electrolytic capacitors, resistors with other passive ...

ABSTRACT This project which consists of four chapters deals extensively with the design and construction of a battery charger which is capable charging a 12 volts, battery. The first chapter which is the introductory chapter goes a long way in defining the battery charger and explaining of the mode of operation. The second chapter went further to explain each component part of the battery charger. This ranges from:- 1. The ...

CHAPTER ONE   INTRODUCTION   WHAT IS A BATTERY CHARGER: A battery charger is a device used to put energy into a secondary cell or rechargeable battery. By forcing on electric current through it. The charge current depends upon the technology and capacity of the battery being charged. For example, the current that should be applied to recharge a 12v car battery will be very different from the current for a ...
