Construction Of A Battery Changer Using Silicon Controlled Regulator SCR
The practical importance of a battery charger in today world cannot be over emphasized. This is so as those batteries accumulators are immensely needed by out auto mobile and in science laboratories.
This thesis describes the methodical approach to the design and construction of any battery charger. However the procedure fro developed cover the construction of battery charger for battery sizes ranging from 6 voltage to 24volatge (heavy duty) batteries.
The prototype of a battery charger for these ranges of batteries has been implemented following the methodical approach as outlined in this thesis and its operational test results are quite satisfactory. adequate care has been taken in the design and construction to ensure that the resultant battery charger are both reliable and easy to use.
1.0 INTRODUCTION
In our society today writing a project is all about applying the theories learnt over the year to produce design and construct and operating system which will be capable of performing a known task.
It is from this point of view that I decoded to write, design and construct this particular project which has the titles construction of a battery charger using SCR (Silicon controlled regulator).
A battery charger is an electric device employed in charging batteries the batteries. The batteries that are usually charged by battery charges are the storage batteries also known as accumulators.
1.1 BACKGROUND OF THE PROBLEMS
The charger is made up of various electrical and electronics components which for purpose of clarity are grouped into four basic units. They are the power supply unit the smoothening circuit the regulatory unit and the regulated direct current (d.c) charging unit.
1.2 AIM AND OBJECTIVE OF THE PROJECT
The aim and objective of this project is to highlight and design how to use SCR to charger batteries. Battery charger been constructed in many different ways but the silicon control regulated type is more sensitive than the ordinary battery charger. This is because it has the ability to indicate or detect full charging of a cell the detector or indicator light will automatically lights up when the battery attains a fully charged cell.
1.3 SCOPE OF THE PROJECT
Battery charger comes in various design voltages and wattages the choice of a particular kind of charger then depends largely on the size of battery or batteries which one intends to charge the miniature battery charger could be needed to charge one battery whose voltage ranges form 6-12voltage the bigger charger are for batteries with voltages ranging from 12-48 voltage. These are the heavy duty batteries. The battery charger that I am about to construct will successfully charge a battery of 250MA or an equivalent 6-12 volts batteries.
1.4 ORGANIZATION OF THE PROJECT
The proceeding chapter of this project is all about the literature review of this project and the indications of a fully charged cell. Chapter three explains the functional block diagram types of charging system. The construction of this project is all stated in detail in chapter four of this report chapter five outlines the summary conclusion component sourcing and references.
