FAQ
What is lithium battery thermal management?
Thermal management uses heat dissipation, temperature control, and monitoring to keep batteries within an appropriate
temperature range, preventing overheating or overcooling, and ensuring safety, performance, and lifespan.
Why do lithium batteries need thermal management?
Battery performance, lifespan, and safety are highly temperature-dependent:
·High temperature accelerates aging and may trigger thermal runaway
·Low temperature reduces capacity and power performance
·Stable temperature improves cycle life and safety
How does thermal management affect battery range and lifespan?
·Stable temperature → lower internal resistance, higher efficiency → longer range
·Avoid high temperature → slower material degradation → longer lifespan
·Avoid low temperature → better discharge performance → more stable operation in cold conditions
Effects of temperature on lithium batteries
·Low temperature: capacity decreases, internal resistance increases, discharge performance deteriorates
·High temperature: accelerated degradation, shorter lifespan, higher risk of thermal runaway
·Optimal range: typically 10 – 35 °C for most stable performance
What is thermal runaway in lithium-ion batteries?
Thermal runaway is an uncontrolled process where the battery’s internal temperature rises rapidly and self-heats continuously, potentially causing smoke, fire, or explosion.
What causes thermal runaway in lithium-ion batteries?
Common triggers include:
·Internal short circuits (damaged separator, metal particles)
·Overcharge, over-discharge, or high-rate overcurrent
·High ambient temperature or insufficient heat dissipation
·Mechanical damage (crushing, dropping, puncture)
·BMS protection failure or improper design
How to prevent thermal runaway in lithium-ion batteries?
·Use safe and stable cells and chemistries
·Optimize structural design and heat dissipation paths
·Employ reliable BMS with overcharge, overcurrent, temperature, and short-circuit protection
·Keep battery operating temperature within a safe range
·Conduct safety tests (UN38.3, IEC 62133, etc.)
·Avoid high-temperature, high-load, or mechanically stressful environments
Does low-temperature heating consume a lot of power?
Using low-power heating strategies and intelligent temperature control, heating power consumption is typically ≤5%, with minimal impact on daily range.
Does heat dissipation design increase battery size?
Integrated structural designs embed heat dissipation components or share them with the enclosure, minimizing additional volume.
