CHAPTER ONE
7.0 INTRODUCTION
7.1 Background of the Study
In
the context of renewable energy source, a device which consists of
electrodes and electrolytes for the storage of chemical energy, but
brings about a reaction between it’s electrodes and the electrolyte in a
ways to cause the flow of electrons through an external circuit is
known as a battery the circuitory to recharge the batteries in a
portable product is an important part of any power supply design. The
complexity and cost of the charging system
primarily depends on the type of battery and the recharge time.
7.2 Charging Formation
In the realm of battery charging, charging methods are usually separated into two general categories.
Fast charging: is typically a system that can recharge a battery in about one or two hours.
Slow
charging: This is usually refer to an overnight recharge, i.e it is
usually defined as a charging current that can be applied to the battery
indefinitely without damaging the cell. (This method is sometimes
referred to as a trickle charging).
The maximum rate of trickle
charging which is safe for a given cell type if dependent on both the
battery chemistry and the cell construction when the cell is fully
charged, continued charging causes gas to form within the cell. All of
the gas formed must be able to recombine internally, or pressure will
build up within the cell eventually leading to gas release through
opening of the internal vent (which reduces the life span of the cell).
This
means that the maximum safe trickle charge rate is highly dependent on
battery chemistry, but also on the construction of the internal
electrodes.
7.3 Types of Batteries
7.4 Primary (Dry Cell):
are those whose electrolyte dries up when used to it’s ampere – hour
rating and cannot be recharge. Dry cell batteries are different from wet
cells because their electrolytes are contained in a low-moisture paste.
Regardless of their sizes, they have the same basic components. At the
center of each is a Rod called the cathode which is often made up of
carbon and surrounded by an electrolyte paste. Different chemicals can
be used to create this paste such as ammonium chloride and managanese
dioxide, depending on the type of battery. The cathode and electrolyte
paste are wrapped in paper or cardboard and sealed into a metal cylinder
called an anode which is typically made of zinc.

ABSRACT - [ Total Page(s): 1 ]This project which comprise of many chapters that deals extensively with designs and construction of battery charger with auto-cut off which is capable of charging a 12 volts battery. In this construction research, designs was carried out which historic research was used to break down and evaluate to a low level understating of what an auto-cut of charger system is all and how it can be constructed and the main purpose of the project. The charging current as well as the power to the circuit is o ... Continue reading---
