Abstract


Electronic Components require direct current (dc) for their effective operation. This direct current can be gotten either by rectifying an alternating current (ac) or Connecting the system to a direct current source which is usually a battery.

It is observed that after some period of operation, the batteries no longer function as expected. This may be as a result of degradation or discharge of the battery. This phenomenon has resulted in economic waste in the past, when only dry cells batteries were used.

In more recent times, engineers taught it wise to device a means of restoring a discharged battery back to life. This advancement brought into existence the invention of rechargeable batteries.

The focus of this work is on intelligent battery charger. This charger may monitor the voltage, temperature and/ or time under charge to give out an output as whether the battery is low or fully charged using seven segment displays.

Introduction

What Is A Battery Charger:

A battery charger is a device used to put energy into a secondary cell or rechargeable battery. By forcing on electric current through it.

The charge current depends upon the technology and capacity of the battery being charged. For example, the current that should be applied to recharge a 12v car battery will be very different from the current for a mobile phone battery.

What Is An Intelligent Battery Charger:

This is a battery charger whose output current depends upon the battery’s state. An intelligent charger may monitor the battery’s voltage, temperature and/ or time under charge to determine the optimum charge current at that instant. Charging is terminated when a combination of the voltage, temperature and/or time indicates that the battery is fully charged.

Other Type Of Battery Chargers

1. Simple Battery Charger:

A simple charger works by connecting a constant dc power source to the battery being charged. A simple charger does not alter its output based on time or the charge on the battery. This simplicity means that a simple charger is inexpensive but there is a trade off in quality.

2. Trickle Battery Charger:

A trickle charger is a kind of simple charger that charges the battery slowly, at the self-discharge rate. A trickle charger is the slowest kind of battery charger.

3. Timer-Based Battery Charger:

The output of timer charger is terminated after a predetermined time. Timer chargers were the most common type for high-capacity Ni-Cd cells in the late 1990s

4. Fast Battery Charger:

Fast chargers make use of control circuitry in the batteries being charged to rapidly charge the batteries without damaging the cells element. Most such chargers have a cooling fan to help keep the temperature of the cells under control.

5. Pulse Battery Charger:

Some charger use pulse technology in which a pulse is fed to the battery. This DC pulse has a strictly controlled rise time, pulse width, pulse repetitive rate (frequency) and amplitude. This technology is used to work with any size, voltage, capacity or chemistry of batteries including automotive and valve-regulated batteries. .

6. Inductive Battery Charger:

Inductive battery chargers use electromagnetic induction to charge batteries. A charging station sends electromagnetic energy through inductive coupling to an electrical device which stores the energy in the batteries

7. USB-Based Battery Charger:

Since the universal serial bus specification provides for a five-volt power supply, it is possible to use a USB cable as a power source for recharging batteries.

Conclusion

The importance of an intelligent battery charger cannot be over-emphasized since there is a high level of inconsistency in other types of battery charger. This is seen in the over charging of battery which is not a good and healthy practices.

This necessitates the need to use an intelligent battery charger as it disengages the battery from the charging circuit once the battery is fully charged.


Recommendations

Due to the economic and technical advantage of a rechargeable battery system over dry cells, we recommend that it should be the pre dominant battery in use for all system.

We recommend that full wave bridge rectifier be used since it requires a smaller transformer without centre tapping. Also the full wave bridge rectifier circuit has less peak reverse voltage (PRV) and it is suitable for high voltage application.

Finally, intelligent charger fast charges a battery up to about 83% of it maximum capacity in less than an hour, then other types of charger. Hence we recommend its wide usage.
