ABSTRACT
A battery charging machine is an electrical device employed for charging batteries. These batteries that are usually charged by battery charger are the storage battery chargers are the storage batteries also known as “accumulator” the battery charger changes. The alternating current forms the power line into d.c suitable for charging.
When the battery is fully changed, is up to it’s maximum set voltage, the charger with automatically stop changing.

1.1 INTRODUCTION
A battery charging machine is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The charging protocol depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle, and some battery types absolutely require, or may use a timer to cut off charging current at some fixed time, approximately when charging is complete. Other battery types cannot withstand over-charging, being damaged (reduced capacity, reduced lifetime) or overheating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge.
A battery charger is an electrical device employed in charging batteries that are usually charged by battery charges are the storage batteries also known as “accumulators”.
The charger is made up of various electrical and electronics component which for the purpose of charging. The basic units of the machine are:
The power supply units
The smoothing circuits
The regulating unit and
Regulated D.C charging units
A Battery charging machine comes in various designs and voltages. The choice of a particular and of charger that depends largely on the size of battery such as 1.5v, 3v, 4.5v, 6v, 9v etc. The battery charging machine 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.
1.2 OBJECTIVES OF THE PROJECT
The objective of the project is to design a device that will recharge batteries of different voltage levels when discharged. The device has the ability to stop charging whenever the battery reaches the set point.
1.3 SIGNIFICANCE OF THE PROJECT
This device charges battery of different voltages, however, if the output voltages are adjusted can be used to charge battery of lower or higher voltages. Apart from charging batteries, this device can also be used as a battery level monitor due to the battery level feature it contains.
1.4 APPLICATION OF THE PROJECT
Battery charger is used in the following devices for the purpose of recharging device batteries:
- It is used in inverter
- It is used in cellphone
- It is used in Solar energy system
- It is used in vehicles
- It is used in an uninterruptible power supply(UPS), etc.
1.5 LIMITATION OF THE PROJECT
The only problem with this device is that it takes longer time to recharge car battery because of the low current output, and it is design only for 1.5v to 9v batteries.
- ADVANTAGES OF THE PROJECT
Features of this automatic battery charger made it more advantageous than other 1. It composes of in-built active components which stop charging process when the battery is fully charged.
- It consumed less current but generate high current to the load.
- It has a manually operated switch that is used to ON and OFF the entire system.
1.6 PROJECT WORK ORGANIZATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
