Battery Management System: Keeping Lithium-Ion Batteries Running Smoothly

A battery management system, also known as a BMS, is an important component used in lithium-ion battery packs. The primary purpose of a BMS is to protect the battery by regulating voltage, current, and temperature. It does this by continuously monitoring individual cells and the overall battery pack performance. Properly functioning BMS are essential for safety and extending the usable life of lithium-ion batteries used in various applications from electric vehicles to consumer electronics. Monitoring Battery Performance One of the key roles of a BMS is to continuously monitor the voltage, current and temperature of each individual battery cell. Lithium-ion batteries cannot be overcharged or over-discharged as it can cause damage or hazards. The BMS monitors cell voltages and balances charging currents to keep all cells within a safe operating window. It prevents any single cell from charging too much compared to others which could cause issues. Temperature is also closely tracked to avoid operation in temperature extremes that can degrade battery performance over time. Cell Balancing for Extended Life Over time small differences in battery cells can occur due to manufacturing variations or uneven aging characteristics. A good BMS performs active cell balancing to keep all cells at an equal state of charge. This prevents any cells from becoming more drained than others which could lead to early failure or unsafe operation.

Cell balancing helps maximize the usable capacity of lithium-ion battery packs and extends their lifecycle. Constant monitoring and active equalization between cells is an important maintenance function performed by Battery Management System. Thermal Management is Critical Heat generated from high charging currents or discharging rates needs to be carefully controlled by a BMS. Lithium-ion batteries can become damaged if the internal temperature exceeds optimum limits, which is why thermal sensors are included. Cooling systems may need to be activated, and charging/discharging can be slowed or halted altogether if temperatures approach unsafe levels. Overheating issues are addressed with precision in electric vehicles where heat dissipation demands are more complex compared to smaller products like smartphones. Advanced BMS precisely control thermal dynamics for longevity and safety. Detect Faults and Warn Users Proactive fault detection is another role of battery management system technology. It analyzes cells for abnormalities during routine monitoring activities. Early warning signs of potential faults like unexpected voltage or impedance changes can be spotted. Users are alerted to battery issues through status indicators so corrective maintenance can be promptly performed. Serious faults are acted upon automatically by the BMS through isolation procedures that prevent further degradation or hazards to the pack. Fault diagnosis capabilities help maintain high health levels in lithium-ion battery deployments. Data Logging and Telemetry Functions Many BMS are equipped with significant data logging functions to help fine-tune performance over the lifetime of the battery. Parameters like charge cycles completed, cumulative energy throughput, and usage history profiles are stored. This information helps determine remaining useful life estimations and identify factors impacting it sooner. Advanced systems include wireless connectivity for remote battery monitoring as well. Real-time telemetry data and log downloads enable predictive servicing by OEMs and optimize battery second-life reuse opportunities in stationary storage applications. Battery Safety Functions Above everything else, battery safety remains the top priority function for BMS. Overcurrent, overpressure, short circuit detection are all critical hazards addressed. Active protections include current limiting circuitry that engages during fast charging/discharging routines. Pre-charge functions slowly condition cells before high power stages. Thermal shutdown switches off battery operation entirely if cells become imperiled. Internal/external isolation relays prevent fired or damaged cells from impacting others. Strict controls applied by BMS safeguard people and property from battery failures leading to fires or explosions. Get more insights on Battery Management System

Analysis of Cell Consistency in Lithium Battery Assembly

The variation in lithium battery parameters, such as capacity, internal resistance, and open circuit voltage, is mainly due to inconsistencies. These inconsistencies occur during production and worsen over time.

Definition of Consistency

Currently, lithium-ion battery consistency means bringing together important characteristic parameters of a group of batteries. It’s a relative concept, with no “most consistent,” only “more consistent.” Ideally, each parameter in multiple cell strings within the same pack should stay within a small range for consistency.

When considering time, consistency involves maintaining all characteristic parameters throughout the entire life cycle of all cells in the lithium-ion battery pack. This helps reduce capacity reduction inconsistency, internal resistance growth inconsistency, and aging rate inconsistency. Ultimately, the focus is on ensuring consistency for the entire pack’s lifespan.

The Concept of Inconsistency

The inconsistency of lithium battery parameters mainly involves capacity, internal resistance, and open circuit voltage. The voltage represents the initial battery voltage during assembly, while internal resistance is the AC internal resistance when fully charged, and capacity is the discharge capacity after full charging.

As the battery undergoes continuous charge and discharge cycles, the state of each cell (SOC, voltage, etc.) becomes increasingly different. Additionally, the varying usage environment within the lithium battery pack affects each cell differently.

This gradual amplification of inconsistency during use can accelerate the performance degradation of some cells and eventually lead to premature failure of lithium battery packs.

Note: SOC refers to the remaining power of the battery and is an important parameter for battery use. It is used to estimate the overcharge and over-discharge of the battery.

Causes of Inconsistency

The inconsistency of lithium battery packs is a gradual process. Over time, the differences between individual batteries within the pack increase. Additionally, the battery pack is influenced by its usage environment. As time goes on, the inconsistencies among individual batteries are amplified, leading to accelerated performance degradation of some batteries and eventual failure of the entire pack.

The inconsistency of lithium battery packs is primarily influenced by two factors:

1. Technical issues and uneven materials during manufacturing result in small differences between battery materials. After the pack is put into use, variations in electrolyte density, temperature, ventilation conditions, self-discharge rate, and charging/discharging processes may lead to differences in capacity and internal resistance among batteries from the same batch.

2. When used in a vehicle, factors such as electrolyte density, temperature, ventilation conditions, self-discharge rate, and charging/discharging processes of each battery within the pack can also impact consistency.

Scope of Evaluation of Consistency

My understanding is that the consistency of all cells is crucial, whether they are in series or parallel. Here’s a simple example:

In a parallel setup, if cells with low discharge capacity (let’s call them B) are connected in parallel with other normal cells to form a module D, they can become a bottleneck in the entire battery pack’s discharge capacity over time due to faster aging.

In a series setup, if a module D in the whole battery pack has aged more than other modules, it can affect the entire pack’s charging process and lead to imbalances in capacity and internal resistance.

Therefore, ensuring consistency across all power batteries is essential, not just within individual modules.

Hazards and Problems Caused by the Inconsistency of Lithium Battery Packs:

Poor consistency can lead to uneven real-time voltage distribution during charging and discharging, potentially causing overvoltage charging or under-voltage discharge, which poses safety risks. Here are the details:

Capacity Loss: The capacity of the weakest cell determines the capacity of the entire battery pack, following the “barrel principle.”

Life Loss: Cells with lower capacity may reach the end of their lifespan sooner due to excessive output during each cycle, affecting the entire group of cells they are connected to.

Increased Internal Resistance: Cells with higher internal resistance generate more heat, leading to accelerated deterioration and further increase in internal resistance.

Lithium batteries use a protective circuit system to ensure safety. Voltage consistency is crucial, as the protection system relies on voltage monitoring. If one cell reaches protection conditions, the battery circuit is cut off, regardless of the status of other cells. Over time, differences in voltage consistency can lead to loss of battery value and potential safety issues, especially if there are individual protection system failures.

Essential Features to Look for in a Lithium Battery BMS

1. Over-Voltage and Under-Voltage Protection

The lithium battery BMS monitors the voltage in the battery and provides the protection required against being over-voltage and under-voltage. Overcharge happens when the voltage is high above the maximum safe limit, but the charge is also low compared to the minimum safe voltage.

Both issues can affect the battery cells’ capacity and lifespan in the short term and in the long term by deteriorating their capacity and lifespan. The BMS will be reliable when it continuously monitors each cell’s voltage on the battery pack and takes the right action, such as switching charging or discharging when needed.

2. Temperature Monitoring and Protection

Lithium-ion batteries are sensitive to temperature extremes that may reduce performance and safety. The excessive heat initiates thermal runaway, an extremely undesirable condition in which the battery temperature increases out of control, leading to a fire or explosion.

Moreover, cold weather can dramatically decrease the battery’s performance and charging performance. A good lithium battery BMS should consider the battery pack’s temperature sensors to control the system and use measures like lowering the amperage of current exchange or shutting down the system when the temperature becomes unsafe.

3. Balancing and Equalization

For the multi-cell lithium-ion battery pack, equality of cell voltage and charge level is the most significant parameter for cell balancing. The cells within a pack are exposed to the environment for a long duration, and they tend to develop slight differences in their capabilities, resulting in an imbalance in the pack.

This causes less capacity and an imbalance of stress on the cells with the passing of time, which shortens the battery. A lithium battery BMS has the capability of cell balancing and recharging inbuilt. 

4. SOC & SOH Monitoring

Conclusion

Making the proper lithium battery BMS, is vital to ensure that you have the safety, performance, and longevity of the lithium-ion battery. BatteryInc, a well-known Lithium Battery Manufacturers in Bangalore, has to offer the BMS with the above characteristic functions.
