EV safety

EVs are as safe as — or safer than — ICE vehicles

Modern EVs score 5 stars in crash tests (Tata Nexon EV, Hyundai Ioniq 5). The heavy battery pack lowers the center of gravity, reducing rollover risk. No fuel tank means no fire risk from spilled petrol.

AIS-156 — India's EV safety standard

All EVs sold in India must comply with AIS-156 (Automotive Industry Standard 156), which mandates:

Battery pack must withstand thermal shock, overcharge, short circuit, crush, and immersion

BMS must prevent overcharging and deep discharge

Pack must pass nail penetration test (individual cell level)

Fire propagation must allow 5+ minutes for passenger evacuation

Thermal runaway — what it is and how to handle it

Thermal runaway occurs when a lithium-ion cell overheats uncontrollably. It is extremely rare in certified vehicles. If you smell burning plastic or see smoke:

Stop immediately and turn off the vehicle

Move away at least 30 metres

Call emergency services (112) and inform them it is an EV

Do NOT open the battery compartment

Do NOT use water unless directed by fire services (they use specialised foam)
