How does a smart battery work? Introduction and Technology

Our lives have been made significantly easier with portable power, and that comes from batteries. In the older times, batteries were not that smart in terms of usage and charging, but batteries today have become many smart thanks to advanced smart battery technology. Today most gadgets and appliances that are a part of our daily life routine are based on smart battery technology.

What makes a battery smart?

The two most common types of batteries are lithium-ion batteries and lead-acid batteries. As the lead acid batteries do not have any smart chips or management boards inside them, they are not smart. On the other hand, lithium batteries have this small circuit board inside them, which makes them smart in different ways.

Smart Charging

The first thing about these batteries is smart charging. Unmonitored charging is unsafe for lithium batteries because they may overcharge and explode at any instant. So, the smart charging technology integrated into these batteries with the circuit board makes these charge safely.

With the help of this controller chip, the battery can communicate its charging requirements, and the controller controls the maximum and minimum power the battery gets for charging. Thus, batteries can be charged safely and efficiently.

Intelligent Usage

Intelligent usage also makes these batteries smart because, with these chips, the device can communicate with the battery. For instance, with different power requirements, a battery may need to provide power at different times. The smart battery system can manage the battery with digital supervision, supplying enough power when needed.

Similarly, it intelligently stops the current supply from the battery when a specific charge limit is reached. Some smart batteries also work in specific temperature ranges to prevent damage.

With such qualities, the battery remains the same, but its usability can be enhanced by adding smart features using the chip technology. Several options are available for smart battery systems, including management boards, safety circuits, etc.

How does a smart battery charger work?

The best thing you can do with your battery is charge it correctly. With the advancements in smart battery technology, some smart battery chargers do not charge the battery as regular chargers do. This way, the battery gets charged adequately, resulting in much better operation. The smart chargers work in 3 different stages, which are as follows:

1.Bulk Charging

The first stage is bulk charging, and, in this stage, the battery gets the highest compatible amperage and voltage possible. The battery can be healthily charged by maintaining the highest compatible voltage and amps rating without causing issues like overheating. This rate at which we can charge the battery is known as the natural absorption rate.

This charging stage only activates when a battery is severely drained, and because the charger is smart, maintaining the highest compatible charging specifications does not cause any risk of damaging the battery. As the charger is smart, the charging specifications automatically drop when the battery charges up to a certain percentage.

2.Absorption Charging

After most of the battery is charged, the absorption charging state starts. During this stage, the charger detects resistance from the battery and the desired voltage. It enables the charger to set voltage and amps to charge the battery after it reaches 80% charging properly yet safely.

During this stage, most chargers use a steady voltage for charging, but to keep it safe, amps are dropped so that a low current goes into the battery. In this way, the battery can be charged without overheating. As the charger drops amps, this stage will take more time.

3.Float Charging

It is the last stage, and it maintains battery charging at a slow rate to maintain a 100% charging state. Different smart chargers work differently, so a charger may enter this stage once the battery reaches somewhere between 85% and 95%.

The charging rate here is so slow that it only manages to keep the battery from idle draining. There are no heating issues, and leaving the battery in float charging mode is safe for months. Thus, whenever you pick the battery, it will be at 100% charging and ready to use.

What is smart battery technology?

The smart battery technology combines a lithium battery and a battery management system. This system holds the technology to maintain the usage of every battery cell. Batteries today mostly use multiple cells; depending on their configurations, there could be different row and column configurations in the cells of your battery.

With the management system, ample battery voltage, current, and power duration can be achieved. Some other features of this technology include:

Battery charge percentage monitoring

Protecting the battery from overcharging and discharging

Continuing optimal performance from a battery with the right optimization

Stopping the system when the battery is not good.

Reporting battery condition to external devices for easier troubleshooting.

Estimating the operational state of a battery.

How does smart battery technology work?

What makes smart battery technology smart is that these systems have no fixed specifications. Instead, any required output can be achieved by correlating different features of the smart system, including:

Battery application

Safety requirements and functional safety measures

Lifespan and warranty concerns

Complexity and design of the battery pack

Battery operational certification requirements

After considering all these features of the smart battery system, battery capacity, and protection can be managed. So, once these are implemented with the battery, the smart technology ensures maximum utilization while maintaining optimum conditions.

Benefits of Smart Battery Technology

Some of the best benefits of smart battery technology include the following:

With smart technology, we can safely use the battery up to its fullest

The technology keeps us aware of the battery's health and charging condition.

Every battery configuration has different needs, and smart technology provides the right usage for that specific battery.

Batteries and their cells can be protected from unsafe usage.

This technology can remember usage and charging patterns and optimizes to provide the best experience.

With all these benefits, a battery can achieve much better performance and lifespan.

Conclusion

Imagining a world without batteries would be impossible because batteries surround us. Everything has a battery in everything from laptops to smartphones, and these are the smart batteries that perform much better in terms of charging, safety, and usability thanks to smart technology.
