Chapter 12: Electric Vehicle Safety, Standards, and Regulations

Prof.(Dr.) D G Mahto, Founder & CEO -

Abstract:

Electric Vehicle (EV) safety standards and regulations ensure protection from electrical hazards, crashes, and fire, covering battery safety, charging systems, and powertrain components through international (ISO, IEC, UNECE) and national bodies (BIS in India) setting mandatory rules and voluntary guidelines like ISO 26262, AIS-156, IS 18590/18606, and UN R100 for vehicles, batteries, and chargers, certified by agencies like ARAI/ICAT to build consumer trust. 
Key Areas of Standards & Regulations:
  • Battery Safety: Focuses on preventing thermal runaway, fires, and explosions through tests for short circuits, overcharging, and thermal propagation (e.g., ARAI's AIS-156 amendment and ISO 6469 ).
  • Electrical Safety: Protects users from electric shock through insulation, isolation monitoring, and safe charging interfaces (e.g., UNECE R100 and BIS IS 17017 ).
  • Powertrain & Components: Standards like India's IS 18590 & 18606 (2024) address the motor, transmission, and energy storage systems for different vehicle types (L, M, N categories).
  • Charging Infrastructure: Covers chargers (AC/DC), connectors, and communication protocols (e.g., BIS IS 17017 and IEC 61851 ).
  • Functional Safety: Addresses failures in vehicle systems, ensuring safety even with component malfunctions (e.g., ISO 26262 ). 
Key Organizations & Standards:
  • ISO (International Organization for Standardization): ISO 26262 (functional safety), ISO 6469 (electrical safety), ISO 17409 (shock hazards).
  • IEC (International Electrotechnical Commission): IEC 62660 (battery), IEC 61851 (charging).
  • UNECE (UN Economic Commission for Europe): UN R100 (unified EV safety regulation).
  • BIS (Bureau of Indian Standards): IS 17017 (charging), IS 18590/18606 (powertrain).
  • SAE International: SAE J2929 (lithium-ion battery safety). 
Certification in India:
  • ARAI (Automotive Research Association of India): Conducts testing and certifies vehicles/components.
  • ICAT (International Centre for Automotive Technology): Also involved in testing and certification.
  • MoRTH (Ministry of Road Transport & Highways): Mandates safety norms like AIS-038 Rev 2 / AIS-156 for batteries. 

So let's deep dive into the Electric Vehicle Safety, Standards, and Regulations
