DESIGN OF AN AUTOMATIC INDICATOR FOR STATE OF CHARGE OF THE BATTERY AND LOAD DISCONNECT.

by kazawadi

Battery is the device that stores electrical energy. Major categories are primary batteries and secondary batteries. Primary batteries become empty cannot be recharged while secondary batteries once used and become empty can be recharged again.

A battery is among one of power sources that has become one of important resources that man can cannot make up life in its absences.

PROBLEM STATEMENT

With experience that there is damage of batteries because of over charging which caused by charging. The system used for particular period of time and hence decrease life span and performance of the batteries.

PROJECT OBJECTIVES.

Main objective.

To reduce damage of the battery due to overcharging of batteries by using charger controller and indicator so as to maintain life span of the battery and its performance.

SIGNIFICANCE OF THE PROJECT.

After the successful completion and implementation of this project following needs ;

  1. Maintaining life span of the battery and its performance and protect them from over charging.
  2. Charger will be able to protect the battery from over charging.
  3. An indicator to determine level of the battery exist before or after charging for a particular period of time.

LIMITATION OF THE EXISTING SYSTEM.

It cannot protect the battery from overcharging, the existing system consists of the transformer, rectification circuit that changes the secondary voltage of the transformer into DC, filter used for smooth DC output and regulator which supply a stable voltage ready to charge the battery.

It does not contain charger controller for switching on/off automatically.

DESGINED SYSTEM.

The system contains major four sections;

Input section

Indication section

Control section

Switching and charging section

ADVANATGES OF DESGINED SYSTEM

It produces regulated charging current to reduce damage and maintain the life span of the battery.

It protect the battery from overcharging

Knowing for stop but in monitoring section

CONCLUSION

The design is successfully to ensure provision of quality battery charger used to charge batteries of 12V.The project is to be beneficial to users since the Analysis and Prototype results were exactly the same for charging that provide constant voltage; monitoring while controlling voltage of the level of battery voltage when full charged hence prevents damage of batteries due to overcharging.
