Description
ABSTRACT
This project is on precedence of an automatic 12v battery charger with charging indicator. This work is aimed at studying while automatic 12v battery charger with charging indicator is preferred over a conventional battery charger.
This battery level device is important because there are many rechargeable devices that use 12v battery.

CHAPTER ONE
INTRODUCTION
- Background of the Study
A battery charger is described as is a device that provides electricity to convert into stored chemical energy for storage in an electrochemical cell by running an electric current through it. [Zhang et al, 2013].
A battery charger consists of a rectifier circuit, power circuit, ripple monitoring, control circuit, regulator circuit.
A Battery charger comes in various designs and voltage. The choice of a particular charger depends largely on the size of battery. Mini battery charger could be used to charge batteries whose voltage is 12 volts.
The battery charge is built in such a way that it delivers a constant value of d.c current into the battery it is charging in the opposite direction from which current flows on the batteries during discharge one cannot successfully design a battery charge without a fundamental understanding of the accumulator because it also makes up the operation according to [Zhang et al, 2013].
This work is aimed at studying the precedence of an automatic 12v battery charger with charging indicator.
- Problem Statement
There is nothing that is so frustrating and dangerous as when a battery is plugged and at the end it was discovered that the battery did not charge. And nothing is as dangerous as when a battery was fully charged and the owner is not aware of the charging state. This automatic 12v battery charger with charging indicator came to solve this problem by making the user to knowwhen a battery is charging and when it is fully charged which can cause the battery not to charged or to over-charge.
1.3 Aim and Objective of Study
The main aim of this work is to study the precedence of an automatic 12v battery charger with charging indicator. The objectives are:
- To know the advantages of an automatic battery charger with charging level indicator over conventional battery charger
- To know why automatic battery charger with charging level indicator is preferred over conventional battery charger
- To know the status of a battery thereby saving the battery from over-charge
- Significance of Study
Carrying this seminar will go along way teaching students the operation of battery charger. This study will also be of great benefit to all users of charger and rechargeable devices in that it will help them to understand how their battery is been charged and how chargers are operated.
- Scope of Study
The scope of this seminar focuses on the study of precedence of an automatic 12v battery charger with charging indicator.
- Definitions of terms
Below are terms that are frequently used in this work and their definitions:
Battery: a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
Charger:a device for charging a battery or battery-powered equipment.
Circuit – a complete path that allows electrical current from one terminal of a voltage source to the other terminal.
Alternating (AC) Current – currents that have a harmonic time dependence.
Ampere (A) – the unit of measurement for electrical current in coulombs per second.
