Project Abstract

Abstract
This research project focuses on the design and construction of a 12-volts car battery automatic charger with a voltage level indicator and a charging process display. The aim of this project is to provide a user-friendly and efficient solution for charging car batteries, ensuring the battery remains in optimal condition. The automatic charger is designed to monitor the voltage level of the car battery continuously. It is equipped with a voltage level indicator that displays the current voltage of the battery. This feature allows users to easily track the battery's status and know when it requires charging. Additionally, the charger includes a charging process display that provides real-time information on the charging progress. This display shows the charging status, such as charging, trickle charging, or fully charged. It enables users to monitor the charging process and ensures the battery is charged safely and efficiently. The construction of the automatic charger involves the use of quality electronic components and a microcontroller for precise control and monitoring of the charging process. The charger is designed to be compact and portable, making it convenient for use in various settings. The automatic charger operates based on intelligent charging algorithms to ensure the battery is charged optimally without overcharging or undercharging. It is designed with safety features to prevent overheating and short circuits, providing a reliable and secure charging solution for car batteries. Overall, the design and construction of this automatic charger with a voltage level indicator and charging process display offer a practical and innovative solution for car battery charging. It provides users with the convenience of monitoring the battery status and charging process, ensuring the battery remains in good condition and prolonging its lifespan. In conclusion, this project presents a functional and user-friendly automatic charger for 12-volts car batteries. The integration of a voltage level indicator and charging process display enhances the usability and efficiency of the charger, making it an essential tool for maintaining car batteries.

Project Overview

1.1 PREAMBLE

Technological development in the third world nation like Nigeria should incorporate finding solutions to seemly small problems like while trying to plan for the big ones. This statement is necessary given that Nigeria having been able to launch NigeriaSat I and about to launch another code named NigeriaSat 2, would be said to be progressive in their approach to technology acquisition and indeed retrogressive applying same to solving little problems.UPS are designed so that there is one source of power normally used called the primary power source and another source that kicks in if the primary is disrupted called the secondary power source. The power from the wall is always one of those sources and the battery contains within the UPS is the other. A switch is used to control each of these powers and the equipment of any given time. The switch changes from the primary of the secondary when it detects the primary has gone out. It switches back from the secondary power the primary power, source has returned.
Contrary to what you might think, the wall A.C power is not always the primary power source and the battery the secondary source. Which source is primary and which is secondary depends on the type of UPS. Therefore, circuit is provided with this UPS to convert AC power to DC to change the battery. A device called an invert is also provided to change the battery stone DC electricity to AC to run your equipment.
Furthermore, those components of the uninterruptible power supply and other one discussed in details in the section covering the various parts of the UPS. The size of the UPS is primary dictated by the size of the time your equipment can run on battery power switching down, higher units not only can power equipment for more time they can also handle a large total demand for power.
The need for a home used charging device is timely, given that daily avoidable accidents occur on our highways due to SLI (starting, lighting and Ignition) faults in motor vehicles.
In Nigeria today there is a wide use of the 12volts Lead Acid Battery. Yet due to the side spread poverty one commuter or vehicle owner chooses to use the same battery over and over again even when the said battery has out lived its usefulness.
