Battery Chargers Circuits-Introduction, Working and Making

Battery Chargers Circuits-Introduction, Working and Making

Page view

Although we use batteries a lot in our daily life, one thing that most of us ignore is the charging of these batteries. Most of the time people are using the chargers that they get without knowing what is happening inside the chargers.

If you are interested to know all about the working of the battery chargers and their circuits, you are at the right place. It is because here we will discuss all about the working of the battery charger circuits.

What is the battery charger circuit?

So, what is a battery charger circuit? This circuit is a collection of many small components that are responsible not only for charging the battery but there are a lot of other functions too that are taken care of by this circuit. Here we will discuss all the functionalities of the battery charger circuit.

What are the basic functionalities of a battery charger circuit?

The following are the basic functionalities of the battery charger circuit.

  • Overcharge Protection

Overcharging is one of the worst things that you can do to your battery. It is because overcharging can also kill your battery. So, most of the battery charger circuits made these are capable of cutting the power from the battery once it is fully charged.

  • High-temperature Protection

When the batteries are charged, heat is produced. It is because the charging is the process where electrons are moved across the different terminals of the battery. So, the battery charging circuits also have this functionality where they automatically cut off the power from the battery once they sense excessive heat production.

  • Reverse Polarity Protection

Reverse polarity is good when we deal in AC, but it is not bearable for the DC systems. So, the polarity must not be reversed while charging the batteries because the batteries work in dc. The battery charger circuits also serve the functionality where they do not allow the system to work unless it is used in the correct polarity.

  • Reverse Power Protection

Sometimes the battery cannot be charged because the circuit is malfunctioning. To make sure that the power is not being drawn back from the battery, the battery charger circuits also have a reverse power protection system.

How does the battery charger circuit work?

The battery charger circuits have different parts that collectively work to provide full functionality. As you are here to know more about the working of the battery charging circuits, here we will discuss the different parts of the circuit and their working as well.

Converting the current into the desired form.

The first part of the battery charger circuit is the transformer. This is the part that is connected to the AC power and its job is to reduce the voltage so that it can be used in the battery charger circuit. At this point, the current is also converted from AC to DC because most of the battery charger circuits use DC as the main power source and output as well.

Converting the voltage and current into the desired value.

The next part of the circuit is required to regulate the current according to the needed amount. This part not only works on the current of the charger, but it can also be used for the voltage, but this depends on the type of charger circuit that you get.

Shutting down when the battery gets fully charged.

The last part of the battery charger circuit is the protection part. This is responsible for shutting down the power from the battery because it senses that the battery is fully charged. The importance of this part of the battery charger circuit can be seen from the incidents where the batteries were exploded or damaged because of being overcharged.

How do you make a battery charger circuit?

If you are looking to make a battery charging circuit by yourself, you will be amazed to know how easy it is to make one. All you need to do is to know your requirements from the charger and you will be good to go.

When you select the requirements, you can face no difficulty in finding the components and once you have all the components, you can easily make a battery charging circuit.

Collecting the components.

The following are the components that you will require for making a battery charger circuit.

  • Transformer.
  • Power regulation component.
  • Diodes.
  • Protection circuits.

Make sure that you know what type of circuit you are going to make because you end up selecting the wrong components, you will be causing a lot of damage to your battery.

Making the charger.

Making the charger is nothing but connecting the components. If you are making a battery charger circuit that works with 200 or 120 volts AC, then you will need a transformer otherwise you will not need a transformer.

If you are making a charger for charging small batteries like the lithium-ion batteries, then all you will need is a component that transfers current from a sub port to the charging circuit. Now the power regulation component will be connected to the power source at one end and the battery connection point at the other end.

Setting the voltage or current according to requirements.

If you have selected the power regulation circuit that can provide variable values, then you will need to change the values according to your requirements. One great thing about this component is that you can charge different kinds of batteries with this one circuit if you add this component to the battery charger circuit.

After you have securely connected all the components, there will be nothing left, and your charger circuit will be ready to use.

Conclusion

A battery charger can bring a lot of ease in our daily lives because it can help us to charge the batteries anytime and at any place with required power availability. As there are different kinds of batteries, there are different kinds of chargers as well.

But the working of these chargers is almost the same. So, here we discussed how these charger circuits work and how you can make your battery charger circuit.
