With the rising adoption of electric vehicles (EVs), safety concerns—particularly thermal runaway in batteries—have garnered significant attention. Thermal runaway can lead to fires or explosions, posing serious risks to lives and property. Understanding its causes and implementing preventive measures is critical for EV safety.
Common Causes of Thermal Runaway
- Collisions
Side or rear impacts can damage battery packs. Using high-strength materials in vehicle design enhances crash resistance. Regular maintenance and timely replacement of damaged components are also essential. - Bottom Impact
Complex road conditions often cause bottom scraping, compression, or punctures, potentially damaging the battery pack. Robust bottom protection designs and durable materials help mitigate these risks. - Foreign Object Penetration
Sharp objects penetrating battery compartments or radiators can trigger thermal runaway. Strengthening protective shields and using resilient materials during manufacturing are key preventive steps. - Short Circuits
Internal or external short circuits, caused by vibrations or technical failures, can lead to thermal runaway. Advanced battery management systems and high-quality components reduce these risks. - External Fire
Exposure to flammable materials or external ignition sources increases fire hazards. Fire-resistant materials and isolation mechanisms in battery design enhance safety. - Immersion
Water exposure from flooding or submerged driving can corrode batteries. Waterproofing measures in design and avoiding water-prone areas during use are crucial. - Vibration and Technical Issues
Inconsistent batteries, relay failures, or fuse malfunctions can cause thermal runaway. Regular inspections and reliable components help maintain system integrity.
