ISO versus IEC •Cultural differences –Automotive sector –Electrotechnical sector •Division of labour ISO TC22 SC21 IEC TC69 Aspects related to the Aspects related to electric vehicle as a whole electrical components and electric supply infrastructure EGVIA 2014 4 Van den Bossche P.
Vehicle performance standards •ISO 8714:2002 Energy consumption and range for battery-electric vehicles –Based on regional test cycles USA EU Japan EGVIA 2014 5 Van den Bossche P.
Vehicle performance standards •ISO 23274 Hybrid-electric road vehicles - Exhaust emissions and fuel consumption measurements –Part 1 Non externally chargeable vehicles (2013 Ed.2) –Part 2 External chargeable vehicles (2012 Ed.1) EGVIA 2014 6 Van den Bossche P.
Drivetrain Component Standards •Extensive standardization for industrial traction motors (IEC 60349) •No demand from automotive industry ! •No tradition in automotor standardization •IEC TC69 WG2 disbanded EGVIA 2014 7 Van den Bossche P.
RESS standards •ISO: Vehicle-centric –Battery system –ISO 12405 family •IEC: Battery-centric –Battery cells –IEC 62660 family –IEC 61982 EGVIA 2014 8 Van den Bossche P.
