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.

Source: Therapeutic Application of Lithium in Bipolar Disorders: A Brief Review

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 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
