A battery charger is an electrical device employed for charging batteries. These batteries that are usually charged by battery charger are 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 charged up to its maximum 13.6 volt, the charger will automatically stop changing with the help of the transistor and the zener diode when bend the current back to the system.

1.0 INTRODUCTION
1.1 BACKGROUND OF THE PROJECTA 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” [Xie, Z.; Liu, Q.; Chang, Z.; Zhang, X. 2013].
A Battery charger comes in various designs and voltage. The choice of a particular and of charger that depends largely int eh size of battery or battery or batteries which on mterds to charge the mini battery changer could be used to charge batteries whose voltage ranges from 6 – 12 volts. The bigger battery changes are for batteries with voltage ranging from 12 – 48 volts. These are the heavy duty batteries (Sequeira, C.A.C, 2011).
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 [Xie, Z.; Liu, Q.; Chang, Z.; Zhang, X. 2013].
The aim of this work is to build a charger that will automatically shut off the charging process when battery attains full charge. This prevents the deep charge of the battery. If the battery voltage is below the 12V, then circuit automatically charges the battery.
1.2 PROBLEM STATEMENT
Sometimes there is nothing worse than losing all the charges on device such as inverter, especially when you are in the middle of something very important. Usually this happens at the most inconvenient time probably when you are using your inverter to surf the web, in the middle of a browsing or when you are desperate to send an important email or text message. A battery charger was introduced which is a portable device that can supply power our device.
1.3 OBJECTIVES OF THE PROJECT
The objective of the project is to design a device that will recharge 12v lead acid battery when discharged. The device has the ability to indicate charging process, low battery and fully charge levels through LED indicators.
1.4 SIGNIFICANCE OF THE PROJECT
This device charges 12v acid battery mainly, 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 [Xie, Z.; Liu, Q.; Chang, Z.; Zhang, X. 2013].
1.5 APPLICATION OF THE PROJECT
Battery charger is used in the following devices for the purpose of recharging device batteries according to (Sequeira, C.A.C, 2011):
- 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.
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 a 12 battery.
1.7 ADVANTAGES OF AUTOMATIC CHARGER
Features of this automatic battery charger made it more advantageous than other types and they are as below (Sequeira, C.A.C, 2011):
- Automatic battery charger has an indicator to indicate when the battery is fully charged
- Built in Indications for showing Full, Empty Levels of any type of battery
- It has a manually operated switch that is used to ON and OFF the entire system.
- 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.
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:
Chapter one of this work is on the introduction to a 12v battery charger. In this chapter, the background, significance, objective limitation and problem of a 12v battery charger were discussed.
Chapter two is on literature review of a 12v battery charger. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed. Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
CHAPTER FIVE
5.1 SUMMARY
Having carefully selected the entire component that are required for the construction of the charger and built according to the circuit diagram we were able to design and construct a workable battery charger.
This charger is not designed for battery whose emf is beyond 12 volts; otherwise the charge output voltage will not be sufficient to carry out any meaniful charging operation.
As with any charger it must be housed in a clean environment and operations should be by well trained individual.
Protective materials should be worn while charging batteries to avoid danger to health as a result of the gassing from the battery as the gas are highly inflammable.
5.2 CONCLUSION/SUGGESTION FOR FURTHER IMPROVEMENT
In the implementation of this project what has proved most difficulties is the selection of the right value of components some were using two diode (the maraine value), in order to have a perfect full wave rectification, we made use of four diodes and a functional portable battery is been designed and constructed.
The charger is very simple to use, over to a Long time all he needs is just a little instruction and it will be accustomed to its method of working.
There is still further improvement demanded from use, mostly in the area of building a work complex and functions charger that could charge cells of higher voltage that might ranges to 48 volts and be able to charge more than two or three battery at the same time having more than one terminal.
