Importance of MATLAB/SIMULINK model in improving the efficiency of the overall solar PV system. Nice project. 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]. The electrolyte is sulphur acid initially of density. Inverter is the electrical device that has used to convert the DC source to AC source that allow the electrical appliances to run safely, however the power quality issue cannot be separate from inverter, this is because in the market now there are several type of inverter. Without use, batteries slowly lose their charge. Title Page ii.

CHAPTER ONE INTRODUCTION 1.1 Background of the study A battery is a device consisting of one or more electrochemical cells that converts stored chemical energy into electrical energy for later use. A built-in microprocessor automatically switches the system from charging to maintenance mode to prevent overcharging. The unit is driven by a transformer whose secondary is usually 14-15 Volts having a current of 3 Amperes minimum. This prevents the deep charge of the battery. 4.2 CASING AND PACKAGING
How to Make A 12V Battery Charger At Home - DIY - Circuits DIY When the battery is fully changed, is up to it's maximum, 12 volt, the charger with automatically stop changing with the help of the contact relay, the transistor and the zener diode when bend the current back to the system. The dilute sulphrine acid is approximately three parts water and one parts suphurie acid the chemical formular of this is H2 S04. Incorporating this versatile IC in the present circuit of a battery charger has made its construction very simple, easily understandable, and the settings part hassle free. Method: The device was first built on a breadboard which is later transfer to vero board and soldered. Next, increase the voltage to about 14.5 volts; this will again make the above LEDs to light up sequentially, indicating the accuracy of the above setting. 1.2 Storage Battery/Method Of Charging, Chapter Two
The sealed lead acid batteries find applications in emergency lightning system, inverters, power electric motors in submarines, generators, etc. High frequency current pulse can be used to recondition batteries that are weak, sulfated or deeply drained. For example, The device has a positive negative. Batteries are generally divided into two groups these are the primary cells and secondary cell which are mostly known as a storage batteries or accumulators. 1.
Due to the possibility of this, it has surely put smiles on the face of most people like some motorist who has long been finding it difficult charging their own batteries at their homes and at their convenient time. Automatic battery charger presented here is a Ni-Cd battery charger. If they sit for long periods, they can also lose the ability to be fully charged. Charge, maintain or jumpstart 6 and 12 volt batteries with this automatic battery charger. 2.1 HISTORICAL BACKGROUND OF BATTERY CHARGER Check Level of electrolyte.
Each 2V cell consists of an independent enclosed compartment with positive and negative plates dipped in electrolyte composed of diluted sulphuric acid solution of 33.5% v/v sulphuric acid and water [7]. At the end of the project we were able to produce a pure sine wave 5KVA inverter with an AC output of 220v, 50hz with a tolerance of 5%.
