Battery Charging Systems – Introduction, Meaning And Work

Nov 25, 2020   Pageview:431

A battery cannot work without enough charge stored in the battery. We can increase the amount of charge available in the battery by charging the battery. However, there are different methods of charging batteries that are recommended by the manufacturers.

Every battery manufacturer comes up with a good way of charging a battery that will not harm the battery. Therefore, it is good to capture the charging information correctly to extend the life of your battery.

Different charging systems are designed for different types of batteries. The system used to charge a phone battery could never be useful in charging a car battery. However, the phone battery charging system is much simpler than the car battery charging system.

Therefore, this writing will be dealing with the charging systems that are used in vehicles. I have to give you the best information concerning charging systems. Thus, follow me through a get the best out of it.

What is the battery charging system?

In any vehicle, the battery charging system ensures that the battery has charge and provides electrical energy used by the radio, lights, and other vehicle components while the car is running. For most modern cars, the charging systems consist of the alternator, battery, wiring, and electronic control unit.

In the early years, the vehicles' charging system was made up of a regulator, but the older cars now have an advanced battery charging method.

The work of the alternator is to create electrical power used to run accessories and recharging the battery. The alternator turns mechanical energy produced by the car’s crankshaft into electrical energy needed by the system.

The computer, also known as the regulator, is a traffic controller by regulating the alternator's current amount. The regulator has a sensing mechanism that helps decide when the battery needs charging or the demand for electricity changes.

On the other hand, that battery acts as a storage device. The primary function of the battery is to crank the engine when starting a car. The battery also supplies the stored energy to other parts of the car that needs electricity.

What does the charging system light indicate?

The charging light plays a considerable role in the battery charging system. If you do not have a charging system light, you are at a greater risk of being stuck. The warning light helps in showing us when something is wrong with the charging system.

The warning light is labeled differently in different car models. The most common labels include 'Gen,' 'Bat,' or 'Alt.' If the warning light shows up while the engine is running, it means an issue in the charging system.

The problem is usually associated with a dead battery or a faulty alternator; thus, it is good to act when you notice that the light has popped up.

Also, the battery charging system light indicates that there is a bad electrical connection. Thus, it will be fair for you to check all the electrical connectors for corrosion and sitting and ensure that the terminals are screwed tightly.

Another cause of warning light is slipping or faulty serpentine belt. The serpentine belt is the reinforced rubber that operates the alternator's pulley and starts the alternator. When the belt is not working properly, the alternator will not run, meaning there will be charging issues.

When a battery terminal is disconnected, the battery charging system light will light. Once you notice the light, it is recommended that you check the battery's terminals to ensure they are correctly connected. If they are connected well, clean the terminals, reattach the cable to the battery, and tighten it.

Sometimes, a dead battery might trigger the battery warning light; therefore, you should test the battery to ensure that it is working normally. You should use a multimeter to test the battery for the correct voltage.

Apart from the issues mentioned above, another thing might turn on the battery charging light. The computer system or regulator is responsible for controlling these lights and ensuring that every component works well. Thus, if the alternator and the battery are in good condition, you should take the vehicle for a mechanical test on the vehicle's computer system issues.

How does a battery charging system work?

The electric current required by a car and its components can be quite large. If the car was designed to get power from a battery, the battery would run down after a few hours. Thus, it was made to have a battery then topped up with a charging system.

The battery consist of a pair of lead plates dipped in a mixture of water and sulfuric acid. The plates are connected to each terminal, and the current injected into the battery causes a chemical reaction that deposits extra lead to one set of plates.

A car battery is charged by an alternator that is driven by a belt from the engine. The alternator has a stator and stationary wire coil windings that allow the rotor to revolve. The rotor is an electromagnet that receives a small supply of electricity through carbon brushes.

The rotation for the electromagnet generates electricity inside the coils. The electricity generated is high, and it is alternating current, meaning the direction of current flow changes back and forth each time the rotor makes a turn.

The electricity produced is then turned to direct current by a set of diodes that ensure that the current flow through them in only a single direction. The battery will only be charged when the amount of current supplied is not too low or too high.

The alternator is designed with a transistor-operated control device that controls the voltage by injecting more or less current into the electromagnet. In some cars, the regulator and the rectifier are housed inside the alternator. They are mounted on the alternator's body in others.

Conclusion

Having an understanding of the battery charging system is essential. The car battery might not be charging, and you fail to know. You now know what the battery warning light might be indicating. Get the best out of your battery charging system and always ensure it is working correctly.
