Battery Thermal Management: The Crucial Role of Temperature Control

In modern electric vehicles (EVs), the lithium-ion battery module pack takes center stage, influencing an EV's performance, range, and safety. However, these crucial power sources are sensitive to temperature extremes. Like people, batteries have their comfort zone, typically operating optimally between 15°C and 40°C. Yet, the reality of automotive environments exposes batteries to temperatures ranging from a frigid -20°C to a sweltering 55°C. What's the solution? Give the battery an air conditioner, and you get battery thermal management, which accomplishes three essential functions: heat dissipation, heating, and temperature consistency.

Heat Dissipation

When temperatures soar, batteries can experience a dramatic loss of life (resulting in capacity degradation) and an elevated risk of thermal runaway. Thus, effective heat dissipation is vital when the battery becomes excessively hot.

Heating

Conversely, when temperatures plummet, the battery's capacity may be reduced and performance weakened. Charging the battery in this frigid state can even pose a risk of thermal runaway due to potential internal short circuits. So, it's crucial to warm up or insulate the battery when it gets too cold.

Temperature Consistency

Think back to the old air conditioner in your childhood home. It would blast cold air upon startup and then take a break. Most modern air conditioners now use frequency conversion and even airflow distribution to maintain temperature consistency. Similarly, power batteries strive to minimize spatial temperature differences, ensuring minimal variance in cell temperature. Temperature consistency is paramount to battery performance and safety.

Effects of Low Temperatures on EVs and Batteries

As the heart of an EV, the power battery has a profound impact on its performance, affecting aspects such as range, acceleration, and service life. Safety is also a top priority. Battery performance is deeply intertwined with temperature, and cold climates can significantly hinder an EV's operation.

For instance, electric vehicle owners in colder regions often notice a significant drop in mileage during winter. In some cases, the range can plummet to as low as 70% of its usual capacity. Many drivers resist using cabin heaters to conserve mileage.

Low temperatures not only reduce an EV's battery capacity but also inhibit its discharge capabilities. At extremely low temperatures, the electrolyte inside the battery may freeze, leading to a severe reduction in power output.

Lithium-ion batteries are particularly susceptible to temperature extremes. At lower temperatures, the chemical reactions within the battery slow down, resulting in decreased performance and range. Charging in freezing conditions can also lead to the formation of lithium deposits on the battery's negative electrode, potentially puncturing the battery diaphragm and causing a short circuit. The safety implications of charging batteries at low temperatures are significant.

Battery Thermal Management: A Technological Solution

Battery thermal management is the solution to many of these challenges. This technology aims to maintain battery temperature within the ideal range. The approach includes both heating and cooling, to optimize battery performance.

There are several methods used in battery heating:

Battery Natural Heating: The heat generated during battery operation, discharging, or charging can increase the battery's temperature. However, this method can be slow and is rarely used in modern electric vehicles.

Blower Heating: Blowing hot or cold air into the battery pack through an external air conditioner is another method. This approach demands a carefully designed air duct and can result in uneven temperature distribution within the battery pack.

Heating Elements in the Battery Pack: These are composed of heating elements and circuits. Two common heating elements are the Positive Temperature Coefficient (PTC) and Heating Film. PTC offers advantages like safety, high thermal conversion efficiency, and rapid heating.

Circulating Liquid Heating: Liquid-cooled battery packs have become the mainstream option. This method offers uniform heat distribution, safety, and reliability. It usually features a system to facilitate heat dissipation, ensuring even temperature rises throughout the battery pack.

Conclusion

Battery thermal management is not just a luxury; it's a necessity for modern electric vehicles. In a world of varying climates, maintaining optimal battery temperature is a key factor in enhancing performance, ensuring safety, and prolonging battery life. As technology continues to evolve, battery thermal management will continue to play a crucial role in advancing the electric vehicle industry, offering the promise of efficient and reliable clean energy transportation for the future.

You’re right, Mrs, eating batteries is not good for you.

Seriously, though, this is the most obnoxious anti-reality take on medication. People with Bipolar Disorder have reduced GABA neurotransmission, which causes cell death in the brain.

Lithium increases those missing GABA and seratonin levels. Your body already needed those chemicals to function, which is why it doesn’t, hence why you get bipolar disorder in the first place!

Of course you need medication to function, that’s why medication exists. To treat a chemical imbalance in your body. If you can’t handle that, please at least consider not spreading ridiculous misinformation on the internet.

I like the fact that the two most well-known uses for lithium are treating people who are bipolar, and making batteries, which are also bipolar but in a completely different way.

Battery Energy Storage System Manufacturer: Powering the Future of Sustainable Energy

In recent years, the demand for renewable energy has surged as the world shifts towards more sustainable and environmentally-friendly power sources. Central to this transition is the battery energy storage system manufacturer industry, which plays a crucial role in storing and managing renewable energy. These systems are vital in ensuring that energy produced by renewable sources, such as solar and wind, can be stored and utilized when needed, even when the sun isn't shining or the wind isn't blowing. As the world continues to adopt renewable energy, the role of battery energy storage systems will only become more important.

What is a Battery Energy Storage System?

A battery energy storage system (BESS) is a technology that allows energy to be stored in batteries and then released when required. These systems are essential for managing the variability of renewable energy sources. For instance, solar panels only generate electricity during the day, and wind turbines only produce power when the wind is blowing. By using a BESS, energy generated during peak production times can be stored and then used during periods of low generation or high demand.

Battery energy storage systems come in various forms and sizes, from small residential units to large-scale industrial installations. A leading battery energy storage system manufacturer typically offers a range of products designed to meet the needs of different applications, from home energy storage to grid-level energy management. ​ The Role of Battery Energy Storage System Manufacturers

Battery energy storage system manufacturers are at the forefront of the renewable energy revolution. They are responsible for designing, producing, and distributing the batteries that power these systems. These manufacturers invest heavily in research and development to improve the efficiency, capacity, and lifespan of their products, ensuring that they meet the ever-growing demand for reliable energy storage solutions.

One of the key advancements in recent years is the development of the 38.4kWh low-voltage stackable battery, a cutting-edge solution that offers enhanced flexibility and scalability for various energy storage applications. This type of battery allows users to easily expand their storage capacity by stacking additional units, making it an ideal choice for both residential and commercial installations.

Key Components of a Battery Energy Storage System

A typical battery energy storage system comprises several key components, each playing a crucial role in the system's overall functionality:

1. Battery Cells

The battery cells are the heart of any BESS. These cells store the electrical energy that can be later discharged to power homes, businesses, or even entire communities. Manufacturers typically use lithium-ion batteries due to their high energy density, long life, and low maintenance requirements. However, other types of batteries, such as flow batteries or lead-acid batteries, are also used in certain applications.

2. Battery Management System (BMS)

The Battery Management System is an integral part of any BESS. It monitors the health, charge, and discharge cycles of the battery cells, ensuring optimal performance and safety. The BMS protects the battery from overcharging, overheating, and deep discharging, which can significantly reduce the lifespan of the battery.

3. Inverter

The inverter is responsible for converting the DC (direct current) stored in the batteries into AC (alternating current), which is the form of electricity used by most household appliances and industrial machinery. High-quality inverters are essential for maintaining the efficiency and reliability of the energy storage system.

4. Energy Management System (EMS)

The Energy Management System controls the overall operation of the BESS, including when to charge and discharge the batteries. It ensures that the system operates efficiently and effectively, maximizing the use of stored energy and minimizing waste. The EMS can also integrate with other energy systems, such as solar panels or wind turbines, to optimize energy production and storage.

Benefits of Battery Energy Storage Systems

The adoption of battery energy storage systems offers numerous benefits, both for individual users and for the broader energy grid:

1. Energy Independence

By storing energy generated from renewable sources, homeowners and businesses can reduce their reliance on the grid, leading to greater energy independence. This is particularly beneficial in areas prone to power outages or where grid electricity is expensive.

2. Grid Stabilization

Battery energy storage systems play a crucial role in stabilizing the grid. They can absorb excess energy during periods of low demand and release it during peak demand times, helping to balance supply and demand. This not only ensures a more stable and reliable power supply but also reduces the need for costly grid upgrades.

3. Environmental Impact

BESS contributes to a reduction in carbon emissions by enabling the increased use of renewable energy. By storing excess renewable energy for later use, these systems help to reduce the reliance on fossil fuels, which are a major source of greenhouse gas emissions.

4. Cost Savings

For consumers, battery energy storage systems can lead to significant cost savings. By storing energy during off-peak times when electricity is cheaper, and using it during peak periods, users can reduce their energy bills. Additionally, many governments offer incentives and rebates for installing BESS, further reducing the cost of adoption.

Challenges Facing Battery Energy Storage System Manufacturers

Despite the numerous benefits, there are several challenges that battery energy storage system manufacturers must address:

1. Cost of Production

One of the biggest challenges facing manufacturers is the high cost of producing battery energy storage systems. While the cost of batteries has fallen significantly in recent years, it remains a significant barrier to widespread adoption, particularly for residential users. Manufacturers are continuously working to reduce costs through economies of scale, improved manufacturing processes, and advancements in battery technology.

2. Battery Lifespan and Degradation

Another challenge is the lifespan and degradation of batteries. Over time, all batteries degrade, leading to a reduction in capacity and efficiency. Manufacturers must invest in research and development to improve the lifespan of their batteries and develop systems that can manage and mitigate degradation.

3. Recycling and Disposal

As the adoption of battery energy storage systems increases, so does the need for effective recycling and disposal solutions. The environmental impact of disposing of old batteries is a growing concern, and manufacturers must develop sustainable solutions for recycling and disposing of used batteries.

4. Regulatory and Policy Issues

The regulatory environment surrounding battery energy storage systems is complex and varies by region. Manufacturers must navigate a range of regulations and policies related to safety, installation, and grid integration. Ensuring compliance with these regulations can be a significant challenge, particularly for manufacturers operating in multiple regions.

The Future of Battery Energy Storage Systems

The future of battery energy storage systems is bright, with significant advancements expected in the coming years. As technology continues to evolve, we can expect to see improvements in battery efficiency, capacity, and lifespan. Additionally, the cost of battery energy storage systems is expected to continue to fall, making them more accessible to a wider range of consumers.

One of the most exciting developments on the horizon is the integration of BESS with other emerging technologies, such as electric vehicles and smart grids. This integration will enable more efficient energy management and create new opportunities for consumers to participate in the energy market.

Conclusion: The Role of Battery Energy Storage System Manufacturers in a Sustainable Future

As the world moves towards a more sustainable future, the role of battery energy storage system manufacturers will be crucial. These manufacturers are at the forefront of the renewable energy revolution, providing the technology needed to store and manage energy from renewable sources. By overcoming the challenges and continuing to innovate, they will play a key role in ensuring that the world can transition to a cleaner, more sustainable energy future.

The development of advanced solutions like the 38.4kWh low-voltage stackable battery is just one example of how manufacturers are pushing the boundaries of what is possible.

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

A Bilevel Equalizer for Lithium-Ion Batteries

Electric-powered vehicles such as drones (UAVs), Electric cars, electric scooters, Bus trucks, etc. are now in widespread use, and recent reports indicate their development is going to accelerate.

Virtually all these types of EVs now use lithium-ion batteries (LIB), but LIBs require electronic equalizer circuits (EQU) to balance the cell voltages. All present versions have cost and/or performance problems. However, a new type of SEMCO’s hybrid EQU called the Bilevel Equalizer (BEQ) has been proposed that avoids these problems.

Electric-powered aerospace and military vehicles such as drones (UAVs) are also undergoing intense development, and these use lithium-ion batteries (LIB) almost exclusively. However, all large LIBs require equalizer circuits (EQU) to balance the voltages of the series of connected cells (perhaps 200 or more), and all EQUs currently in use have certain cost and/or performance problems.

However, previous references have described a new type of hybrid EQU called the Bilevel Equalizer (BEQ) that mitigates these problems. This present study provides further insight into the BEQ design and proposes possible criteria that can be used for designing both the active and passive parts of the system.

Most large LIBs presently use passive equalizers (PEQ), which simply use a transistor to connect a resistor in parallel with each cell until it discharges to the same level as the lowest cell voltage in the pack. A typical circuit is shown in Fig. 1.

Fig. 1. Basic PEQ Circuit

PEQs are popular because they are simple and cheap, but heating and energy loss are obvious disadvantages. PEQs also are of no use during discharge since they cannot transfer charge to lower voltage, and thus the Ah discharge capacity of the battery is equal to that of the worst cell in a pack of perhaps 200-300 cells.

This problem is usually not important when the cells are new and well-balanced, but as they age, large variations develop, and the loss in discharge capacity due to even 1 or 2 weak cells can become serious.

This reduces the useful life of the battery, which of course increases the lifetime cost. PEQ heating problems also must be considered. This severely limits the size of the equalization currents, typically to less than 200-300 mA, and this limits the ability of the PEQ to equalize the pack when large imbalances are present.

There are several types of active equalizers (AEQ) that transfer charge between cells and thus avoid the problems with PEQs, but they are rarely used due to their complexity and much higher cost. All of these prove to be expensive even for modest AEQ currents, and the cost becomes prohibitive for the higher AEQ currents that are required for large cell imbalances and load currents.

The limitations of PEQs are widely recognized, but since presently available AEQs bring new cost and complexity problems, designers of battery management systems (BMS) have avoided them. Another problem is system inertia. Once a company has an operational BMS with a PEQ, they are reluctant to change, especially if the advantages of an AEQ do not become important until after a few years of service. Thus, these problems persist, and if left uncorrected they will degrade the lifetime performance of these large LIB applications.

BILEVEL EQUALIZER

This quandary has motivated the design of a new EQU that provides performance close to an AEQ but with only a modest cost increase above a PEQ. This circuit is a hybrid AEQ/PEQ called the Bilevel Equalizer (BEQ) because it provides equalization at two different voltage levels. In this system, the battery is organized into sections of a series of connected cells. The AEQ portion balances the section voltages, and there is a PEQ for each section which balances the section cells. This is especially advantageous for large applications such as those for electric aerospace vehicles because the BEQ can be implemented by adding an AEQ to an existing PEQ system with only minor changes to the original hardware. Fig. 2 (a) shows the AEQ circuit that constitutes the active part of the BEQ.

(a) Schematic

(b) Current in L1

In this system B1 – B3 represent sections of a series of connected cells. The number of cells/sections is usually 4 to 14, and for sections of 12 -14 cells, the efficiency is typically in the range of 85 to 90%. Components Q1, Q2, and L1 constitute one AEQ unit, so this circuit has 2 units. To transfer charge from B1 to B2, Q1 is turned on for 0 < t < t1, and i1 flows into L1. At t1, Q1 turns off and i1 flows from L1 into B2 via the body diode of Q2. The period t2 – t1 is less than t1 because of a slight gap in the FET gate drive signal and parasitic losses.

Since the B’s can consist of any number of cells, a 196-cell battery might be organized into 14 sections of 14 cells each. This would only require 13 AEQ units (number of sections – 1), whereas an AEQ with a bidirectional DC-DC converter for each cell would require 196 AEQ units. Therefore, if both types are operated at the same value of equalization current, the cost of the AEQ in the BEQ will be much lower than using an AEQ for each cell.

Another important cost advantage is the absence of the transformers that are present in virtually all other AEQs. AEQs with a DC-DC converter for each cell are presently limited to EQU currents less than 1 Adc, and they are still quite expensive even at these low current levels. Currents in this range also are inadequate for larger batteries that might require EQU currents in the range of 5 Adc or more. Because of its relative simplicity and the low number of AEQ units, the circuit in Fig. 1 can easily be designed to economically provide equalization currents in these higher current ranges.

The block diagram of a BEQ where the cells are divided into 5 sections is shown in Fig. 3. This might represent a 60-cell LIB with 12 cells/section and a maximum voltage of about 240 Vdc. This system uses a PEQ for each section to provide equalization at the cell level for the cells in that section. AEQ units identical to those in Fig. 2 (a) are used to equalize the section voltages. The AEQ boxes shown in blue in Fig. 3 are the only new hardware items needed to convert a PEQ to a BEQ.

Fig. 3. BEQ for a Battery with 5 Sections of Cells

Although the conversion of a PEQ to a BEQ does not require any significant hardware changes, it does require new software since the equalization strategy is different, e.g., the PEQs now drain the cells to the lowest cell voltage in each 12-cell section instead of the entire pack.

Conclusion

Despite their power losses and lack of equalization during discharge, PEQs remain the most common type of EQU due to their lower cost. AEQs provide much better performance, but they are rarely used because of high cost and complexity. This present study, alone, shows that SEMCO’s BEQ hybrid provides an attractive solution since its performance for large imbalances is much better than a PEQ, and its much lower component count and absence of transformers indicate a much lower cost than an AEQ of equivalent size.
