What is the difference between a smart and a normal battery charger?

There were not a lot of options in the world of battery chargers, but now things have changed a lot. The most effective type of charger we used today is known as the smart charger, and it is packed with technology that makes it better than the normal charger. Multiple differences in these chargers set them apart regarding charging time, safety, and battery life.

What makes a smart battery charger different from a normal charger?

The smart charger comes with technology that makes the charging process smart. At the same time, the normal charger is only made to provide a stable supply of electricity to the battery.

It does not have different charging specifications for different charging phases, which makes it far inferior to smart charging. The technology in smart chargers brings multiple features, including:

Automatic Charging

The first one is automatic charging. It is also the most important feature of a smart charger since these chargers are programmed to charge the battery in a balanced manner. This charger communicates with the battery to see which charging phase is currently going on and provides a charging environment for the best life of the battery.

In this way, the battery is safely charged, and in most cases, the battery is charged quickly since a lot of heat is not produced.

Sparking Protection

The next feature is sparking protection. Sparking occurs when the charger terminals are not connected in a stable way to the battery. The lack of a stable connection is bad since it causes sparking, which can cause damage to the charger and battery, and it can even start a fire depending on the environment. The smart chargers detect if sparking is occurring, and it stops charging for safety.

Polarity Protection

Batteries are made to store direct current, and connecting wires according to the correct polarity is very important in these batteries. Connecting the battery in the wrong way to the charger can start the charging process in the reverse direction, which is bad for the battery.

In the case of a lead acid battery, this mistake can even cause a fire. So, smart chargers come with polarity protection. If you wrongly connect the battery terminals, these chargers don't start charging. Thus, both the battery and charger are safe.

Can you charge the smart battery with a regular charger?

The answer to this question depends on the battery you are trying to charge. There are different types of smart batteries; the main difference is their smart chip. So, depending on the chip permissions, you have the following experiences:

What makes the smart battery prevent you from using a regular charger?

The first experience is when a smart battery restricts you from using a normal charger. The battery managing chip in that battery only supports smart chargers. So, as long as the battery management system does not communicate with the charger, the charging process does not start.

As a normal charger cannot communicate with the BMS, that charger cannot charge your smart battery. It is more of a safety feature than a restriction since the BMS wants to charge the battery cells in a balanced manner.

What type of smart batteries can be charged with a regular charger?

Some smart batteries do not restrict you from using a regular charger. Although you can charge them without a smart charger using a regular charger, it is not recommended to do that for a long time. It is because a normal charger does not come with automatic charging programs.

So, it maintains the same charging specifications no matter how much a battery charges. Meanwhile, the BMS in smart batteries tries to maintain balanced charging. While there is no communication from the charger, that can be a little difficult for the BMS, and the charging safety won’t be the same.

Is it safer to use a regular charger than a smart charger?

No, it is not safe by any means. There are no protection features like reverse polarity, sparking, overcharge, or over-discharge protection. Additionally, it does not charge the battery automatically, so the charging process is unsafe.

Is it necessary to have a smart charger?

A smart charger wasn't necessary some time ago, but it has become very important now. More battery applications are moving towards smart batteries due to their potential benefits over unmanaged normal batteries. Here are the top 3 reasons why having a smart charger necessary for everyone:

You can track charging.

When you use a smart charger, it allows you to track the charging process. It is because these chargers can connect to the internet and communicate all the data from the battery to your smart platform, which is most commonly a smartphone application. So, you don't need to physically monitor the charging process while all the information is always available on your smartphone.

You can control charging.

Smart chargers have multiple charging modes, and you get control over the charging process. Say that you are using a smart charger with your car; you can control to charge it quickly in a short time by consuming more electricity.

Similarly, you can use a slow overnight charge to save electricity costs. Thus, you are the master here, and everything about your battery's charging is controlled.

It offers a better life for your battery.

Smart chargers provide a better life for the batteries. The most commonly used battery type today is the lithium-ion battery, and it charges in 3 phases which are:

Pre-charge that involves the initial charging percentage

Constant current charging that involves mid percentages up to 80 or 85. It is the fastest.

Constant voltage charging involves the top few percent. It is the slowest.

So, a smart charger can charge your battery according to the percentage and voltage/current requirements. Thus, the life of the battery increases.

Conclusion

As the name says, a smart charger is packed with technology that makes it superior to a normal charger in several ways. When using one instead of the other, you can use a normal charger instead of a smart one. However, it is not the most recommended thing to do, and the outcome is not great either, especially in the long run. So, the best you can do is use the right type of charger with the right type of batteries.
