A Charge Controller with Integrated Battery Management System for stand alone Application

Project Title

A Charge Controller with Integrated Battery Management System for stand alone Application

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

Three-stage battery chargers are regularly alluded to as brilliant chargers.They are great chargers and are well known for charging lead-corrosive bat-teries. Preferably, notwithstanding, all battery types should be accused ofthree-stage chargers. For the more costly lead-corrosive battery, this threestage charging measure keeps the battery sound. As the name states, thereare three phases in this charger: mass, assimilation and buoy. About 80per-cent of the battery is charged in the mass stage. A steady current of 25percentof the Ah rating is given. For instance, on account of 100Ah battery, 25Aof consistent current is taken care of and voltage increments with time. Atthe retention stage, the leftover 20percent of the battery is charged. Thecharger takes care of the consistent current same as the ingestion voltage ofthe charger, which relies upon charging choices and this current utilizationdiminishes until the battery is completely energized. In the buoy stage, thecharger attempts to keep up the completely energized battery in a similarstate uncertainly. Voltage is diminished and a current of under 1percent ofthe battery’s ability is applied. You can leave battery charging in this stateperpetually and no mischief happens to the battery

Project Objectives

To charge the battery in three stage.

To extand Battery life.

To make like smart Charger Battery. (9Ah  to 200Ah)

Leave the charger into a battery for long deuration  it can't effect on Battery. 

Project Implementation Method

First of all we Implement on protues software because of having the correct connection and protuction.after checking the result on software we wll Implement on hardware.

we will provide input 220v the charger will conduct the requirment of battery and then the battery will charge in his stage.

This cgharger will works on the basis of battery requirment . 

Benefits of the Project

This charger can be charge from 9Ah to 200Ah battery.

Charge battery in three stage. You don’t ever have to worry about leaving the charger on the battery for too long. and no harm occurs to the battery.

This three-stage charging process keeps the battery healthy.

Technical Details of Final Deliverable

The final deliverable of this project wer been applicable to detect Battery requirment.and tis will work on the basis three stage BULK stage, ABSORBTION  stage and FLOAT stage.

1. Bulk stage

About 80% of the battery is charged in the bulk stage.

Constant current voltage increased with time.

There is no risk of overcharging in this stage because the battery has not even reached full yet.

2. Absorption stage

Smart chargers will detect voltage and resistance from the battery prior to charging.

After reading the battery the charger determines which stage to properly charge at.

Once the battery has reached 80% state of charge, the charger will enter the absorption stage.

The current continuously declines until the battery almost reaches full capacity.

3. Float stage

Either way the float stage brings the battery all the way through and maintains the 100% state of charge

Most smart battery chargers do not turn off at this point. yet it is completely safe to leave a battery in float mode for months to even years at a time.
