What is the smart battery standard?

For years we have been using simple batteries which were unable to communicate anything with the device they were powering. Although we were getting things done, that was not the most efficient way of utilizing and charging batteries since there was a huge performance gap.

That's where the smart battery standard makes a revolutionary improvement in the battery industry. This standard makes batteries smarter, so now a battery can communicate with the device and the charger for efficient utilization, performance, and charging.

Smart Battery Data Specification

Traditionally, batteries have been using only 2 connection wires to flow electrons, which gave power to the device. However, things are much different with smart batteries. The smart batteries are designed with a battery management system inside the batteries that transmit operational data about the battery. This data includes:

Battery voltage

Battery current

Temperature

Battery code

State of charge

These things are critical for telling the performance and health of a battery. For instance, if the temperature of a battery rises, it is not good for the battery. The SBMS will automatically detect the rising temperature, and it may cut off the connection to the battery to lower its temperature until it reaches the safe temperature range.

Battery Transmitting Data

Battery detecting its charging and health parameters is not enough for smart devices. So, the SBMS is designed to communicate that data with the operating system running on the device it is connected to. In this way, the battery transmits all the relevant information to the device using it, and from there, users can track their battery's data specifications.

Better and Safer Informed Decisions

One of the biggest applications of battery data specifications communicated with users is that they can make informed decisions. For example, if a battery has served its life and is starting the degrade, the SBMS will tell the user about the health of that battery.

That way, they can upgrade to a new battery before the current one dies, leaving the device unusable. Similarly, it provides lots of predictability benefits. In older days, batteries were degrading unexpectedly, and some were exploding. When all the required data is communicated with users, the chances of such things happening significantly decrease.

Smart Battery Technology

Smart battery technology is the latest revolution that uses efficient battery technologies like lithium-ion and combines them with smart technology. That technology comes with a unit known as the smart battery management system, the SBMS, or a BMS.

Efficient Performance

Smart battery technology is designed to bring enhanced and efficient performance of batteries. Previously there was no method of controlling the output a battery gives, and the power reduction methods were simply wasting power by converting it into heat, etc. with smart battery technology, we improve the life, range, and charging time of batteries with sensors and monitoring.

Battery packs can output different power variations in different charging states and vice versa when charging the battery. By collecting battery data and utilizing it accordingly, better performance can be yielded from the same battery.

Safety

Safety is another major benefit of smart technology since batteries are prone to catching fire and exploding mainly due to high temperatures. With temperature and performance monitoring in real-time, the batteries are only utilized within their safe operating range, which ensures that there are no safety issues, and it may decrease the on-spot performance. Still, it is extremely beneficial for the health and safety of the battery.

Easy Integration

Getting a new batter and setting it up with your device is as easy as it gets. It is because there are highly capable ICs in both the battery management system and the host device. As a result, these devices and batteries can communicate with one another, and most of the integration work on the software side is done automatically. Users only need to integrate the hardware, which is no more than wired connections.

Environmentally Friendly

When we utilize batteries correctly, they can last longer, making an environmentally friendly benefit. It is because when you are not frequently replacing the battery, lesser batteries will end up in landfills since most are not recycled. So, smart battery technology brings benefits to the environment.

Smart Battery Charger Specification

The basic specifications of the smart battery charger are the same, including current and voltage ranges. The real magic about these chargers comes from the microprocessor that brings all the smart charging features. This microprocessor chip communicates with the BMS and sets the required charging conditions per the battery situation.

Such chargers are only designed to work with smart batteries since these batteries can transmit data, while the basic batteries cannot. The best specifications and features of smart battery chargers include the following:

Automatic Phase Charging

The first specification of these battery chargers is automatic charging. These chargers charge batteries according to their state of charge and state of health. Usually, lithium-ion batteries are charged in three phases: precharge, then there is constant current charging, and lastly, constant voltage charging.

The smart chargers detect the right voltage and current your battery needs for the most efficient charging considering the least time-consuming, best battery safety, etc. It is not something you find in other chargers.

Cut off protection.

A cut-off voltage or current is the amount of voltage or current when the battery does not need more. It also means that the battery is fully charged, and you must stop charging it. The smart chargers have cut-off protection built-in, which automatically disconnects charging from the battery.

As a result, your battery is never overcharged. Even if you keep it connected, it will stay in a constant voltage charging phase, keeping the battery topped up.

Spark and Reverse Polarity Protection

These chargers also have reverse polarity and spark protection. The charger will not start if any of these problems happen. Thus, you get amazing security measures with the charger.

Conclusion

With the smart battery standard, a battery becomes smart, and with the help of a management system, it can communicate with the charger or the device it powers. The benefit of that is smart power management, depending on our conditions. Common examples include remaining charging time, remaining usage time, heat, etc. smart battery systems also ensure to charge batteries by balancing individual cell charging for the best efficiency.
