AI based BMS in Lithium-ion Explained

TECHNOLOGY BLOGS

A Battery Management System (BMS) is a crucial component in modern battery-powered devices, especially those using Lithium-Ion and LiFePO4 batteries.

AI based BMS installation with Lithium ion battery

It monitors and controls various parameters to ensure optimal performance, safety, and longevity. The importance of BMS in Electric vehicles and inverters/UPS or storage solutions is a very different need comparatively. The Inverter/UPS has a built-in charger and discharger, so the limits of charging and discharging are already known. https://en.wikipedia.org/wiki/Battery-management-System-In-Lithium-And-Lifepo4-Battery. The major function of the Battery Management System is to control the charging voltage and charging current limits and the discharging current and low voltage battery cutoff. Fast charging may not be an important parameter in inverter/UPS and storage solutions. In solar storage solutions, the charging can be done in 3 to 4 hours, which is much faster than the Tubular lead Acid battery, which takes a minimum of 12 hours to charge. Lithium Cell balancing is a major challenge in most Battery Management Systems as it’s either done with Active or passive equalisation. https://suvastika.com/installation-of-ai-based-bms-with-lithium-ion-battery/

“Battery Management System”

Key Functions of a BMS:

Monitoring of Battery Management Systems (BMS)

Battery Protection: The BMS plays a key role in protecting the battery from conditions that could lead to damage or failure:
- Overcharging: Both Li-ion and LiFePO4 batteries have specific voltage limits. Overcharging can lead to thermal runaway (for Li-ion) or overheating and cell degradation. The BMS monitors the voltage of each individual cell and disconnects charging when the maximum voltage is reached.
- Over discharging: Discharging a battery below a certain voltage can damage the cells or reduce their capacity. The BMS ensures that the battery doesn’t go below the safe voltage threshold by cutting off discharge if necessary.
- Overcurrent Protection: Both high charge and discharge currents can be damaging. The BMS protects the battery from excessive currents, which could cause overheating, swelling, or even fire.
Cell Balancing:

Lithium-based batteries typically consist of multiple cells connected in series or parallel. In a battery pack, these cells can have slightly different voltages due to manufacturing variances or usage over time. The BMS ensures cell balancing, where it actively manages the charging of individual cells to ensure they are charged to the same voltage level. This helps:

Improve overall performance and capacity.
Extend the battery lifespan by preventing overcharging or over discharging of individual cells.
Avoid safety risks, as imbalanced cells can lead to overheating or failure of the battery.
State of Charge (SOC) & State of Health (SOH) Monitoring:

The BMS continuously monitors the State of Charge (SOC) to estimate how much energy is remaining in the battery, which is crucial for determining remaining runtime and ensuring efficient operation.
SOC: The BMS uses voltage, current, and temperature data to calculate the SOC of the battery. This allows for accurate readings on how much energy is available in the pack.
SOH: The BMS tracks the State of Health, which reflects the battery’s ability to hold charge over time. As a battery ages, its capacity decreases. The BMS provides insight into the remaining useful life of the battery, helping to prevent unexpected failures.
Voltage Monitoring: Continuously monitors the voltage of each cell to avoid over voltages or under-voltage conditions which is recorded in to in built memory card which has the 16GB memory to keep the data for 25 years of functioning of AI based Battery Management System.
Prevents cell damage and potential fires.
Current Monitoring: Monitor the current flowing into and out of the battery to prevent excessive current, which can lead to overheating and reduced lifespan.
Temperature Monitoring:

Lithium-based batteries are temperature-sensitive, and their performance and safety can degrade significantly if they operate outside of their recommended temperature range (typically 0°C to 60 degree C for charging and -20°C to 60°C for discharging).
Monitors the temperature of the battery cells and provides protection against overheating or undercooling.
Prevents thermal runaway (especially in Li-ion batteries), which can lead to fire or explosion, by disconnecting the battery when dangerous temperature thresholds are reached.
Communication With External System:

The BMS often includes communication interfaces (such as CAN bus, SMBus, or UART) to provide information to external systems, such as:
Charging devices: It can inform the charger of the battery’s state (e.g., SOC, temperature, and voltage) to optimize the charging process and avoid damage.
Inverter or load management systems: For applications like electric vehicles (EVs) or renewable energy systems, the BMS can communicate data to optimize power delivery and energy use.
Safety and Failure Detection:

A BMS ensures that any abnormal behavior is detected early:
Short-circuit protection: It detects if a short circuit occurs and disconnects the battery from the load to prevent damage.
Fault diagnosis: The BMS can log and report issues with individual cells or components, such as a failing cell or faulty temperature sensor, allowing for maintenance or early replacement before catastrophic failure occurs. In Su-vastika AI based BMS there is a reader card built in in to the BMS which records all the data and that data can be retrieved through any method of IOT or GSM or OBD.

Key Differences Between Li-ion and LiFePO4 Batteries and BMS Role:

Effective Monitoring of BMS Cells: Ensuring Safety, Balance, and Performance

https://suvastika.com/battery-management-system-bms-in-lithium-and-lifepo4-battery/

Lithium-Ion Batteries:

Voltage Range: Typically, Li-ion cells have a nominal voltage of around 3.7V, with a fully charged voltage of 4.2V and a discharge cutoff at 3.0V.
Safety Considerations: Li-ion batteries are more prone to thermal runaway if overcharged, over discharged, or exposed to extreme conditions. The BMS is particularly critical in these applications to ensure the battery stays within a safe operating range.
Energy Density: Li-ion batteries generally have higher energy density than LiFePO4, making them suitable for applications where space and weight are important (e.g., smartphones, laptops, electric vehicles).

Performance:

Optimizes battery performance by balancing cells and maintaining optimal temperature.
Extends battery life by preventing excessive stress on individual cells.

Reliability:

Ensures consistent and reliable operation of battery-powered devices.
Minimizes downtime and maintenance costs.

Lithium Iron Phosphate (LiFePO4) Batteries:

Voltage Range: LiFePO4 has a lower nominal voltage (around 3.2V) and a fully charged voltage of 3.6V, with a discharge cutoff at 2.5V.
Safety: LiFePO4 batteries are inherently safer than Li-ion batteries due to their stable chemical composition, which reduces the risk of thermal runaway. However, the BMS is still needed to protect against overcharging and undercharging.
Lifespan: LiFePO4 batteries typically have a longer cycle life (up to 5,000 cycles or more), making them well-suited for applications that require long-term durability (e.g., solar energy storage, electric buses).

The Price of a Battery Management System (BMS) can vary significantly depending on factors such as the number of cells it manages, its features (like active balancing and communication protocols), and the intended application, with more advanced systems typically costing more

Conclusion:

The BMS is a cornerstone in maximizing the performance, safety, and longevity of both lithium-ion and Lifepo4 batteries. It ensures that the batteries operate within their safe parameters by monitoring voltage, current, temperature, and state of charge, while also providing protection against potential failures and hazards. Without a BMS, these batteries would be prone to significant safety issues, reduced lifespan, and inefficient performance.
