What Does a Smart Battery Do?

If you have been using batteries for a long time, you must be aware of the technological advancements that have taken over this industry. We have so many batteries today that it becomes hard to understand which is best.

But the most impressive advancement that will never confuse anyone is smart batteries. These batteries offer the most advanced features and the best overall performance.

So, what is a smart battery, and how is it different from regular batteries? We will be answering this question today. We hope this information helps you make the best buying and user decisions.

Smart Battery Specification

Overcharging, over-discharging, and overheating have been problems in the battery industry for a long time. Conventional batteries have memory effects and other features that make them extremely hard to maintain. They lose capacity much faster when exposed to extreme temperatures.

Smart batteries come with an internet electronic circuit and sensors that will detect various parameters. They can sense voltage and current levels, among other factors like battery health, and then communicate the same to the device and, hence, to the user.

Such information is crucial when it comes to making those important user decisions. You want to know how much health your battery has so that you can charge or replace it with a more effective one. Also, you can leave your device charging the whole night, and nothing will happen because charging stops at 100%.

When the battery overheats, the communication system will send information to the device to turn it off. This saves the battery from exploding and gives it more life. You can always ensure the best performance from your battery and the device.

Specifications

Here are the features that make a smart battery smart:

Single-wire Bus

We have discussed communication between the battery and the device, which is crucial in delivering the best performance. But you need to understand how this works to get that picture.

Among the most crucial features that make this possible is the Single-wire or 1-Wire bus that communicates via one wire at a low speed. Dallas Semiconductor Corp designed the system. It works by combining data and clocks into a line for easy transmission.

The phase code separates the data at the receiving end, letting you know the exact data you want. This system also stores the battery code and also tracks battery data like the voltage, current, temperature, and state of charge. Thus, it lets you know when to charge the battery or when you should consider a new one.

System Management Bus

There is also the system management bus, commonly called an SMBus, which shows an effort to activate a single communication protocol and a specific data set. With this system, it would be tough to get the right data whenever an action is needed.

The SMBus seeks to remove charge control and let the battery be in charge. Hence, a true SMBus allows the battery to become the master and the charger a slave, obeying every command from the battery. With such batteries, a universal charge can easily serve present and future batteries by delivering the correct algorithm.

Levels 1, 2, 3

Smart batteries come in three levels of SMBus charging, 1, 2, and 3. Level 1 is no longer in existence since it does not give chemistry-independent charging. A level 2 charge receives full control from the smart battery and becomes the slave. It is an in-circuit charging, very common in laptops.

Level 3 charging can easily interpret the smart battery's commands and become the master. This means a level-3 charger can also make its own decisions, aside from the data it gets from the battery, making it more effective.

Smart Battery System

A Smart Battery System (SBS) is all about placing system intelligence inside a battery pack to offer more convenience and create a perfect battery. The system communicates with a charge management chip and other parameters to ensure the battery charges safely and remains in great condition.

Even though most SBSs still rely on an analog signal from the chemistry battery to end a charge, it still offers more flexibility. Also, the system features a redundant temperature-sensing functionality that improves battery safety.

The SBS is a specification for managing the smart battery, especially in portable computers. It all comes down to safe and effective charging, where the SBS allows the operating systems to do power management tasks through the charge. It does this by focusing on the estimated run times and determination of the exact state of charge reading.

This specification was designed by Duracell and Intel companies in 1994 before becoming a part of most battery and semiconductor manufacturers.

The SMS determines the SMBus connection you will make, the data to send over the connection, the smart battery charger, and the device BIOS interface, providing control. That means any battery-operated product can be installed with an SBS and will work well.

Another crucial component of this system is a special integrated circuit in the battery pack, a fuel gauge, or Battery Management System. You may have already heard about this system that monitors the battery and delivers the necessary information to the SMBus. This data could include the battery type, model number, manufacturer, charge/discharge rate, battery health, battery empty alarm, and more. It allows the device to shut down properly while protecting it from temperature and voltage issues for fast charging.

Smart Battery Price

As you may have already guessed, smart battery costs more than normal batteries. This is because it has more advanced features that make it safe and perform better.

The exact price depends on the battery's quality, capacity, size, performance, and application. This can range from a few dollars to thousands. For instance, a smart iPhone battery can cost about $50, while a high-end EV battery will cost you over $10000. It all depends on what you want and how much you want to invest.

When buying a battery today, ensure you check the specifications we have mentioned here. It might be a bit expensive, but investing in smart battery offers more benefits in the long run.
