Design And Construction Of A Smart Inverter Battery Charger
ABSTRACT
This project is on a Smart Inverter Battery Charger. The smart inverter battery charger circuit presented in this work will automatically charge a 12V battery, or above. Special features of the charger are as follows. It automatically controls the charging current as per the status of the battery. Battery voltage level as well as charging status are indicated on the LCD display. The charger maintains float voltage, if battery is fully charged. Arduino identifies status of the battery connection and voltage, and indicates the same on the LCD.

CHAPTER ONE
1.0 INTRODUCTION
- Background of the Study
A battery charger generally 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 building a digital battery charger which comprises of an arduino and LCD an the major component.
1.2 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 study solve problems such as not knowing when a battery is charging and when it is fully charged which can cause the battery not to charged or to over-charge.
1.3 OBJECTIVES OF THE PROJECT
The main aim of the project is to build an arduino smart inverter battery charger. The objectives of the work are:
- To build the prototype of the device
- To automatically controls the charging current as per the status of the battery.
- To display the charging status of the charging battery on the LCD
1.4 SIGNIFICANCE OF THE PROJECT
Using this smart inverter battery charger will serve as a means of keeping a battery in good condition in that the charger maintains float voltage, if battery is fully charged. Arduino identifies status of the battery connection and voltage, and indicates the same on the LCD.
Apart from charging batteries, this device can also be used as a battery level monitor due to the battery level and digital display features.
Carrying this work will go along way teaching students how battery charger is been made and 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.
1.5 APPLICATION OF THE PROJECT
Smart inverter 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.
1.6 LIMITATION OF THE PROJECT
The only problem with this device is that it takes longer time to recharge inverter battery because of the low current output, and it is design only for a 12 battery.
1.7 SCOPE OF THE PROJECT
The scope of this work covers building a smart inverter battery charger that is built around Arduino Uno (Board1), adjustable voltage regulator LM338 (IC1), 12V voltage regulator 7812 (IC2), 16×2 LCD (LCD1) and a few other components. The system automatically controls the charging current as per the status of the battery. Battery voltage level as well as charging status are indicated on the LCD display. The charger maintains float voltage, if battery is fully charged. Arduino identifies status of the battery connection and voltage, and indicates the same on the LCD.
