Li-ion Thermal Management

Lithium-ion batteries in EV’s Lithium-ion batteries are widely used in Electric 2, 3 and 4-wheeler vehicles with varied power capacities ranging from 1 kWh – 5 kWh for 2-wheelers and more than 5kWh for 3-wheelers. Since the electrochemistry of Li-Ion batteries are temperature sensitive, an improper control of thermal conditions in battery application can result in a multitude of issues and concerns.

Existing solution offered by PLUSS Flood and Fill (F&F) technology – This is a low to moderate thermally conductive PCM with a liquid form- factor. This form-factor allows the battery back to be immersed inside liquid PCM. This process would require the outer casing of battery pack to be leak proof.

Management of Li-Ion batteries

Especially in a hot country like India where temperatures are known to reach 50 Degrees Celsius, is crucial because:

  • Prolonged exposure of Li-Ion batteries to ambient temperatures higher than 45°C results in loss of performance over time with consistently reduced output.
  • Battery pack, when not thermally well managed to operate within safe temperature limits can lead to thermal runaway of cells damaging the battery pack.
  • Increase in reaction kinetics at higher temperatures (more than 45°C) can sometimes lead to uncontrolled exothermic reactions within the battery, leading to accelerated heat generation and even explosion.
  • Moderate overcharging can lead to high temperatures that cause inhomogeneity in the electrolytic composition, ultimately leading to short circuits.
  • Battery pack life decreases drastically when operated consistently at high temperatures during lifetime.

PCM melting process for EV battery pack

Value proposition for the Electric Vehicle and Battery pack manufacturers

  • Improved range – By increased useable capacity of the batteries by 25%.

FAQs

What is Battery Thermal Management and why does it matter in EVs?

Battery Thermal Management ensures that lithium-ion batteries operate within safe temperature limits. Overheating or thermal runaway can lead to reduced battery life or safety risks. PCM-based systems passively regulate temperature, improving EV efficiency and performance.

How do PCM materials help in Battery Thermal Management Systems?

Phase Change Materials (PCMs) absorb and release heat during battery charge–discharge cycles. This passive thermal management reduces the need for active cooling, minimizes energy consumption, and extends the usable life of batteries in EVs and energy storage systems.

What is the difference between active and passive thermal management?

Active systems use fans or liquid cooling, requiring external power and maintenance. Passive thermal management, enabled by PCMs, controls battery heat naturally—without added energy cost—making it ideal for compact, lightweight battery packs.

How does PCM technology help prevent thermal runaway?

PCM absorbs heat when a cell temperature spikes, delaying or preventing thermal runaway from spreading between cells. This containment enhances battery safety, especially in high-energy-density EV and aerospace applications.

What industries use PCM-based Thermal Management Solutions?

PCM thermal solutions are used in electric vehicles, hybrid buses, telecom backup systems, defense, and renewable energy storage. These applications demand reliable, maintenance-free cooling that withstands varying climates and operating conditions.

How does PCM improve EV battery range and efficiency?

By maintaining optimal cell temperature, PCM reduces internal resistance and ensures consistent discharge performance. This improves energy efficiency and extends EV driving range, even under rapid acceleration or high ambient heat.

Why choose PCM Thermal Management over traditional cooling systems?

PCM cooling is lightweight, energy-efficient, and silent, eliminating pumps, compressors, and refrigerants. It’s ideal for manufacturers seeking sustainable, maintenance-free battery thermal management systems aligned with next-generation EV design goals.

How does PLUSS’s PCM technology improve Battery Thermal Management for EVs and energy storage?

PLUSS’s Battery Thermal Management Solutions use advanced Phase Change Materials (PCMs) to absorb and release heat during charging and discharging cycles, ensuring consistent cell temperature and preventing thermal runaway. This passive thermal management enhances battery safety, efficiency, and lifespan—delivering lightweight, maintenance-free thermal management systems ideal for EVs, hybrid vehicles, telecom, and renewable energy storage applications.
