⚡ VoltSens Verified Automotive Research & Analysis
Thermal runaway occurs when an internal short circuit or external heat source causes a lithium-ion cell to release flammable gases and oxygen simultaneously, creating a self-sustaining chemical reaction. Following stringent AIS-156 regulations, modern Indian EVs have built-in multi-layered safety barriers.
4 Warning Signs Before a Battery Malfunctions
1. Sweet, pungent chemical smell resembling nail polish remover or burning acetone.
2. Hissing, whistling, or popping noises coming from the underbody battery pack.
3. Excessive heat radiating from the floorboard seat when parked.
4. Sudden rapid drop in dashboard battery percentage (e.g. dropping from 80% to 10% in 1 minute).
